Okay, I'm looking to create a parametric enclosure in OpenSCAD, and I'd like the design to be fairly flexible so I can reuse it for different projects. I've got a basic design in mind, and I'm hoping you can help me make a robust, reusable OpenSCAD file.

Here's what I need:

*   **Basic Box:** The enclosure should be a simple rectangular box with a separate lid.
*   **Parameters:** I need to be able to control the following dimensions using parameters:
    *   `enclosure_inner_length`: The inside length of the enclosure.
    *   `enclosure_inner_width`: The inside width of the enclosure.
    *   `enclosure_inner_depth`: The inside depth of the enclosure.
    *   `enclosure_thickness`: The thickness of the enclosure walls.
    *   `cover_thickness`: The thickness of the cover/lid.
*   **Lid Fit:** The lid needs to fit snugly onto the enclosure, and the fit should be adjustable. I'd like to have a parameter that controls a small offset between the lid's inner dimensions and the enclosure's outer dimensions so it can fit nicely. Something like an overlap on the outer wall of the enclosure to guide the lid into position.
*   **Screw Mounts:** The lid should be attached with M3 screws and captured nuts. I'd like there to be a way to adjust the placement of the screw mounts and the nut traps in the corners of the lid. I need clearance for the screw head and nut. I am planning on using standard M3 hex nuts.

*   **Part Selection:** I need the ability to choose which part to render. This will let me print just the enclosure, just the lid or both at the same time. This could be done with a string parameter with options: `"enclosure"`, `"cover"`, and `"both"`.

*   **Library:** I am not using any libraries but I am not opposed to using established libraries if there is a clear advantage.

I'd like the code to be well-structured and easy to understand, so I can easily modify it later. It would be fantastic if you could include comments in the code.

I think this pretty much sums up what I am after. Please let me know if you have any questions. I'm looking forward to seeing what you come up with.

Okay, I'm looking to create a set of school supplies using OpenSCAD, and I'd like an AI assistant to help me design a single, parametric file that combines all three of my existing designs. I have three separate .scad files for a ruler, a pencil topper, and a pencil case, and they're designed with certain goals in mind. I want to be able to adjust parameters to change each of these individual components within the same file.

**Overall Goals:**

*   **Good Functionality:** Each item needs to work well for its intended purpose.
*   **No Sharp Edges:** All items should have rounded or smooth edges for safety.
*   **Sturdiness:** They should be reasonably durable.
*   **Moderate Material Use:** They shouldn't be overly wasteful of plastic.
*   **Acceptable Aesthetics:** They should look reasonably nice.

**Specific Designs:**

Here’s a summary of the components and their key parameters I want to be able to control:

1.  **Ruler:**
    *   **Length:** I need a parameter for the total length of the ruler (`l`). I currently have it at 160mm.
    *   **Glue Plane Width:** The width of the area designed for applying the scale,  `w1` , currently set at 16mm.
    *   **Scaffold Plane Width:** The width of the main body of the ruler, `w2`, currently at 16mm.
    *   **Blade Thickness:** The thickness of the base of the ruler, `h1`, currently set at 1.5mm
    *   **Ruler Thickness:** The total thickness of the main body, `h2` currently at 4mm.
    *  **Stopper Thickness:** The thickness of a small "stopper" around the oval, `dt`, currently at 0.75mm
    *   **Truss Rim Thickness**: The width of the supports for the ruler `a` is currently at 2mm.
    *   I need the ruler to have rounded ends that protrude slightly above the main thickness of the center, and an area to glue a paper scale onto it. I don't want sharp edges anywhere and would like to maintain the truss structure for rigidity.

2.  **Pencil Topper:**
    *   **Pencil Diameter:** Parameter to specify the diameter of the pencil it's meant to fit on, `dpencil`. I currently have this at 7mm.
    *   **Outer Diameter:** The maximum diameter of the topper, `d1` currently at 18mm.
    *   **Initial Height:** The height of the first section, `h1`, defined by `dpencil+2`.
    *   **Second Diameter:** The diameter of the second part, `d2`, set at `d1/22*19`
    *  **Second Height:** The height of the second part, `h2`, set at `h1*1.33`.
    *   The topper should have the general shape with the outer section and have a hole for the pencil. I'd also like to keep the smiley faces for indication.

3.  **Pencil Case:**
    *   **Main Diameter:** Roughly the main diameter of the case, `d0`, set at 50mm.
    *   **Height of Half:** The height of one half of the case, `h0`, currently set to 125mm.
    *   **Wall Thickness:** The thickness of the walls, `t`, currently set to 1mm.
    *   **Amplitude:** The amplitude of the wave pattern, `a`, currently set to 0.2mm.
    *   **Period:** The period of the wave pattern, `p`, set to 6mm.
    *   **Overlap Factor:** This controls how much the two halves overlap, `overlapfactor`, currently at 0.33.
   *   I'd like to maintain the wavy vase-like design for the case, with two interlocking pieces (extending and shrinking).

**Parametric Design Requirements:**

*   I want to be able to use a single OpenSCAD file that uses parameters to control all the dimensions and features of all three objects in that file, so I need an option to create only some of the parts and also to adjust their positions. For example I'd like to be able to set a variable that if set to true it will include the ruler in the build and also adjust the position of the pencil case and the topper.
*   It's important that I can change the sizes and some other key parameters without having to edit the core code, for example changing the smileys, or if I need to add a new stopper.
*   I'd like to keep the ability to change some tolerances on the parts. For example to make it more or less tight to get the parts of the pencil case together.

**Libraries:**

I am not using any external libraries.

Could you please generate a single, parametric OpenSCAD file that encapsulates these three designs?

Okay, I need help designing a parametric pencil clip that attaches to a binder. I've been using a basic one I made, but I think it could be better and more easily customized. I've attached the OpenSCAD code of my current design which you can review.

Here are the key features I need:

1.  **Binder Clip Structure:** The design needs a clip that securely attaches to a standard binder. The binder's thickness should be a parameter that I can adjust. The clip should have a rounded top, no sharp edges or bridging.
2.  **Pencil Clips:** It should have multiple clips to hold pencils, spaced evenly along the length of the binder clip structure. The number of pencil clips should be a parameter, as well as the diameter of the pencils. The pencil clips need to securely hold pencils, and should not have any bridging either.
3.  **Parametric Design:** I need all the key dimensions to be parameters:
    *   `height`: Overall height of the clip.
    *   `width`: Overall width of the clip (length along the binder).
    *   `thickness`: The thickness of the material of the clip.
    *   `binder_thickness`: The thickness of the binder the clip will attach to.
    *   `pencil_diameter`: The diameter of the pencils that will be held in the clip.
    *   `clip_number`: The number of pencil clips.
    *   `inset`: The offset of the pencil cylinders from the side of the main clip.
    *   `clip_gap`: The amount of space between the support structure for the pencil and the pencil itself.
4.  **Supportless Printing:** The entire model should be designed to print without the need for supports. I think that's mostly accomplished by using cylinders, but I'm open to suggestions.
5.  **Ease of Use:** The parameters should be straightforward to understand and modify, preferably with comments to explain what each one does.

Essentially, I want a robust, customizable pencil clip that's easy to print and use. I would prefer that the design only use the base OpenSCAD functionality, rather than relying on specific libraries. However, if you feel that a library makes the task simpler and more effective, I am open to that as well. If so, please do not assume I have the libraries, and if possible provide the specific commands to use when installing it.

Please let me know if you have any questions or need additional information. I'm really looking forward to seeing what you come up with!

Okay, so I need a custom power bus designed in OpenSCAD, and I want it to be parametric so I can adjust it later. I've got a few specific requirements that I'll detail below.

Basically, I need a way to connect multiple devices to a power source using standard M3 screws and wires. This design should allow for the "rails" to be stacked, where a two rail bus is simply a duplicate of a single rail bus.

**Core Features:**

*   **Multiple Slots:** The design needs to support a variable number of connection slots. I want to specify how many individual connection points there are.
*   **Dual Bus Option:** I need the ability to have two identical buses stacked on top of each other, for more positive and negative connections. This should be an option that can be toggled.
*   **Quad Bus Option:** Similarly, I need an option to have two of the double buses next to each other (as a mirror), resulting in a quad bus.
*   **Threaded Rod:** The whole thing needs to be held together with a threaded rod that passes through the entire assembly. I will need to be able to specify the diameter of this rod.
*   **Cable Accommodation:** Each connection point needs space to accommodate a wire. I should be able to specify the maximum diameter of the wire I'll be using.
*   **M3 Screw Terminals:** Each connection point will have an M3 screw and nut for securing the wires.
*   **Cosmetic Option:** It would be nice to have a cosmetic toggle that switches between "normal" mode, "show insides" mode, and "all solid" mode. "Show insides" mode would render just the outer frame of the bus. "All solid" mode would render just the complete bus.

**Specific Parameters I Want To Control:**

*   `slots`: The number of connection slots along the bus.
*   `double`: A boolean (0/1) to enable or disable the dual bus option.
*   `quad`: A boolean (0/1) to enable or disable the quad bus option.
*   `bus_rod_dia`: The diameter of the threaded rod used to connect the bus assembly.
*   `cable_dia`: The maximum diameter of the wire used in the connections.
*   `invert`: An integer (0, 1, or 2) to control the cosmetic display mode, `0` for normal, `1` for show insides, and `2` for all solid.
*  `mm_per_slot`: the spacing between slots, in mm.

**Additional Notes:**

*   I am assuming that I am using a standard M3 screw and nut, so you can use those predefined sizes for the model.
*   The dimensions for the bus overall are not as important as the ability to specify the number of slots and the threaded rod diameter.
*   I'd like the design to be reasonably robust for 3D printing, so a little bit of extra material around the threaded rod and screw holes for strength would be appreciated.
*   No external libraries are needed.

Could you please generate an OpenSCAD file based on these specifications? I've already got an existing design, which is included above. If you could just build from this as a start, that'd be great.

Okay, I've got this OpenSCAD file that's a pencil box with a hinged lid and a latch, and it also embosses some initials on the top. It's kind of a mashup of a few things I found online, but I want to make it more customizable and a little easier to tweak. I'm hoping you can help me create a parametric version of it.

Here’s what I'm working with:

**Basic Box Structure:**
*   The pencil box has a bottom and a top that fit together with a hinge.
*   It has a latch mechanism that hooks onto the bottom.
*   There's space for embossing initials on the top and bottom.
*   The box is generally rectangular.

**Key Parameters:**

*   **`width`**: The width of the pencil box.
*   **`depth`**: The length (depth) of the pencil box.
*  **`height`**: The height of the pencil box.
*   **`wallThickness`**: The thickness of the walls.
*   **`hingeOuter`**: The outer diameter of the hinge.
*   **`hingeInner`**: The inner diameter of the hinge.
*   **`hingeInnerSlop`**: The slop between the hinge pin and the barrel.
*   **`hingeFingerSlop`**: Slop around the hinge fingers (the bits that interlock).
*   **`fingerLength`**:  Length of the hinge fingers - currently calculated off hingeOuter, but would be nice to adjust independently.
*   **`fingerSize`**: Size of hinge fingers (also currently calculated off hingeOuter)
*	**`topFingerSize`**: Allows for independent sizing of the hinge fingers in top half.
*   **`latchWidth`**: Width of the latch.
*   **`message`**: The text to emboss on the box - this should be configurable in the UI (or a list of strings for multiple locations)
*   **`Font`**: Which font to use for the embossed text (should select from a list of common fonts)

**Hinge Details:**
*   The hinge is a series of interleaved fingers (the interlock pattern) along the back side.
*   The hinge has a central pin.
*   The hinge includes a locking feature to ensure parts can't twist around the center pin, like a small tab along the rotation on each section of the box.

**Latch Details:**
*   The latch is a semi-circular bar that hooks into a receiver on the bottom piece.
*   It has a hinge at the latch end which also has a small hook.

**Embossing Details:**
*   The initials should be embossed (raised) on both the lid and base
*  I'd like to select from a list of fonts, or even be able to import my own DXF fonts.

**Libraries:**

*   The existing file uses custom libraries for writing text (`Write.scad`) and creating wedges (`wedge.scad`). I think `Write.scad` relies on the elmom-MCAD-8930770 library, so it should be noted that it's a dependency. It also includes another, custom `configuration.scad` file but we probably don't need that to start with as it seems to just define some paths to the libraries.

**What I'm Looking For:**
*   I'd like a single, parametric OpenSCAD file that has all these parameters easy to adjust.
*   I'd love for it to have good comments so I understand how it's all put together
*   It would be fantastic if the font selection was a drop-down or easily configurable with file name or enum values.

Essentially, I want to be able to easily customize the box size, hinge details, latch size, and the embossed initials. It would be ideal if it were clean, well-structured and very easy to understand.

Let me know if you need any more details. Thanks!

Okay, I'm looking to design a customizable stackable box in OpenSCAD and I'm hoping you can help me. I've already got a good basic structure, but it has some limitations, and I want it to be more robust.

Here's what I'm aiming for:

**Core Functionality:**

*   **Stackable Box Design:** The primary function is to create a box with a lid that's designed to stack securely with other identical boxes. This stacking should be achieved through a recessed frame on the bottom of the box that mates with a corresponding frame on the lid.
*   **Parametric Dimensions:** Everything should be driven by parameters, allowing me to easily adjust the box's size and features. Key dimensions are:
    *   `inner_x`: The internal length of the box along the X-axis.
    *   `inner_y`: The internal width of the box along the Y-axis.
    *   `inner_z`: The internal height of the box, up to where the stacking frame begins.
    *   `stack_z`: The height of the stacking frame itself.
    *   `stack_gap`: The gap between the box's bottom and the stacking frame, effectively controlling the size of the stacking recess.
    *   `wall`: The thickness of the box's walls.
    *   `bottom`: The thickness of the box's bottom.
    *   `cover_height`: The overall height of the lid, including the stacking frame.
    *   `ear_radius`: The radius of the corner "ears" (anti-warp supports)
    *   `ear_height`: The height of the corner "ears" (anti-warp supports)
*   **Cover/Lid:** There should be a separate module to generate the lid/cover. The cover should have the stacking frame feature on top, to allow stacking a box on it.
*   **Anti-warp "Ears":** The box (both box and cover) should include optional anti-warping ears at the corners. These should be cylindrical pads placed at the bottom of the object. I'd like to easily toggle them on or off.
*   **Support Prevention:** There is a known issue with the current design that may need an improved solution. The support-prevention part that is currently implemented by using `hull()` to connect a slightly bigger part at the bottom of the stacking recess is not ideal, so an improved version or a parameter to disable support-prevention would be appreciated.
*   **Support prevention start-height:** The support-prevention part starts a certain height above the ground to prevent printing unnecessary support. This start-height should be configurable.

**Additional Considerations & Improvements I'd like:**

*   **Improved Support Prevention:** Instead of the somewhat hacky hull method, I would like something more robust to prevent support inside the box while still maintaining the correct fit for stacking. Maybe a simple "support_prevention_method" variable with options `none, simple, advanced`
*   **Tolerances:** Right now the fit is really tight. I need to be able to configure the tolerances between box and lid. Perhaps an extra parameter like `tolerance`.
*   **Rounded edges:** I would like an optional parameter to add a radius to the top of the box walls (where the cover rests). This would make it more pleasant to handle and also possibly help with the printing.
*  **Stacking Direction:** Currently, the stacking direction is implied by the position of the box and the lid, but it should be made explicit by the design. Maybe a parameter like `stacking_direction = "up", "down"` or a similar value to modify the code appropriately. If the direction is down, the stacking frame on the lid should be on the bottom and vice versa. This would allow to create trays.
*   **Customizable Corners:** It would be great if I could choose between different types of corners. Perhaps parameters like `corner_type = "sharp", "rounded", "chamfered"`, and if rounded or chamfered, a `corner_radius` parameter.
*   **Clear Parameter Definitions:** I need the code to be well commented, with clear explanations of each parameter.

**Specific Library Requirements:**

*   I'm not using any external libraries right now, and I'm hoping not to add too many. However, if you think there is a particular library that would significantly simplify the code, feel free to suggest it (but please justify why it is necessary and preferred over a built-in solution). I'd prefer not to depend on external libraries if possible.

**In summary, I want a highly customizable parametric box and lid for stacking, with robust anti-warp features, improved support prevention, adjustable tolerances, and flexible corner styles.**

Could you please provide me with the OpenSCAD code that addresses all these points? Thanks!

display_cover = "yes"; // [yes,no]
// Display the box
display_box = "yes"; // [yes,no]
// Create ears at the corner

// the x length inside the box (the resulting x of the box is inner_x + 2*wall)
inner_x = 45;
// the y length inside the box
inner_y = 80;
// the z height inside the box, until the stacking frame begins
inner_z = 13;

// the z height of the stacking frame
stack_z = 5;
// per side gap between the box-bottom and the stacking frame (box bttom = inner_x + 2*wall; inner stackingframe x = inner_x + 2*wall + 2*stack_gap)
stack_gap = 1;

// wall thickness
wall = 2.5;
// bottom thickness
bottom = 1;

Okay, I'm trying to design a piece of chainmail, specifically a Spiral 4-in-1 weave, and I'd like to be able to customize it easily. I've already got a basic SCAD file that gets me part of the way there, but it's not quite what I need. I need a design that's more robust and flexible.

Here’s what I’m looking for:

**Core Requirements:**

*   **Spiral 4-in-1 Weave:** The design should create a chainmail-like structure that follows the Spiral 4-in-1 weave pattern.  I’ve included a link in the prompt for reference: http://www.mailleartisans.org/weaves/weavedisplay.php?key=21.
*   **Parametric Design:** I need to control the number of rings, the wire diameter, the aspect ratio of the rings (inner diameter / wire diameter), and the spiral angle of each ring as it progresses down the chain.
*   **Ring Geometry:** Each ring should be a simple torus shape, made using `rotate_extrude` on a circle. The design should use the `smoothness` parameter to control the number of facets in the circle.
*   **Consistent Spacing:** The rings need to be spaced logically to form the spiral. The existing code provides the basic translation formula, but it might need refining.
*   **Locking Mechanism:** A crucial feature is that the ends of the chain need to be "locked" to prevent the chain from unwinding.  I'm not entirely sure how to do this, maybe by welding two adjacent rings at the end or some other mechanism to ensure the end rings can't spin.

**Specific Parameters:**

*   `numRings`: Integer, the total number of rings in the chain.
*   `wireDiameter`: Float, the diameter of the wire used to form the rings.
*   `ringAR`: Float, the aspect ratio of the rings (inner diameter divided by wire diameter). I believe for a 4-in-1 weave this should be above 3.4, with good results starting around 4.0.
*  `angle`: Float, the angle of rotation for each ring relative to the previous one.
*   `smoothness`: Integer, the smoothness factor, dictating the number of facets in circles.

**Desired Improvements/Changes from the Provided SCAD:**

*   **Locking:**  The most important change is incorporating some kind of locking mechanism on the end rings to prevent the chain from unwinding, possibly a small weld or a bent hook on the wire ends. I am open to creative solutions here. I think a weld on the ends is best.
*   **Modularity:** I want the design to be flexible enough that I could easily chain together sections of this weave in the future if desired (perhaps using the locking mechanism).
*  **End Ring Design:** Instead of simply closing the chain on the last ring, I would like the last ring to be of a different design, namely a hook which can hook to a separate single ring (i.e. a jump ring). I can then use this last ring to attach to other objects. The first ring should have a simple weld of wire ends.
*   **Potential for Variation:** I'm open to suggestions for variations on this, e.g., changing the cross section of the wire used, or slightly altering the spacing between the rings. If I find a variation particularly useful, I will request it be made a parameter.
*   **Code Quality:** Please make the code clean and easy to understand, with comments to explain the logic.

**Libraries:**

I am not asking for any libraries at this time. I assume any required math will be included in the generated file itself.

Could you generate a parametric OpenSCAD file that fulfills these requirements? I would like the core requirements and parameters to be included.

Spiral4in1_Customizer.scad:
```
// preview[view:south, tilt:top]

numRings = 8;
// Diameter of ring in mm
wireDiameter = 2;
// Aspect ratio of the ring (Inner diameter/Wire diameter)
// Spiral 4:1 has a minimum of 3.4. However, ring placement is illogical below 4.0 (due to the actual weave bunching up, yet still being possible). Choose something slightly above 4.0 to ensure no fusing errors.
ringAR = 4.05;
angle = 25; // [25:60]

// Smoothness factor (larger = smoother, but longer to generate stl)
smoothness = 20;

union()
{
	for (i = [1:numRings])
	{
		rotate([angle*i,0,0])
		translate([i*(wireDiameter*ringAR+wireDiameter*2+wireDiameter/100)/3,0,0])
		ring(wireDiameter, ringAR);
	}
}

module ring(wd, ar)
{
	rotate_extrude(convexity = 10, $fn=smoothness)
	translate([ar*wd/2+wd/2, 0, 0])

Okay, I'm looking to create a customizable chainmaille weave design in OpenSCAD, specifically the Jens Pind's Linkage (JPL) weave. I've already got a basic version working, but it's not as flexible as I'd like and could probably use some optimization.

Here's what I need:

*   **Variable Length:** The number of links should be easily adjustable. I want a parameter, something like `numRings`, to control the length of the chain.
*   **Ring Diameter Control:** I need to be able to specify the wire diameter of the rings, perhaps with a parameter called `wireDiameter`. This should directly affect the size of the rings.
*   **Ring Aspect Ratio (AR) Control:** The aspect ratio of the rings (inner diameter / wire diameter) needs to be adjustable using a parameter, maybe `ringAR`. The working range for JPL is usually between 2.7 and 3.1; outside of that the weave will fail to form correctly or fuse. I need to make sure the design correctly changes the angle of each ring as the `ringAR` changes.
*   **Smoothness Parameter:**  The circles for the rings should be generated with a smoothness variable, such as `$fn`, but controlled through a top-level parameter I can change. I'd like this to be an integer, maybe called `smoothness`.
*   **Correct JPL Weave Geometry:** The core geometry needs to generate the JPL weave as described in the description. The chain should not connect unless in the JPL pattern. As mentioned before, this includes accounting for the angle change of the links as the AR changes.
*   **Single `.scad` file:** I would prefer to get all of the code in a single file, so that it can be easily copied and used.
*   **No external libraries** Unless absolutely necessary, please do not use any external libraries for this design. I would prefer pure openscad code, to keep the file portable.

I want all of these parameters to be easily adjustable at the top of the file.

Essentially, I need a parametric OpenSCAD module that generates a JPL chainmaille section, where I can easily control the length, ring size, aspect ratio, and smoothness of the rings. The rings should be correctly angled to create the JPL chain, which is dependent on the ringAR.

Can you help me with this?

JPL_Customizer.scad:
```
// preview[view:south, tilt:top]

numRings = 8;
// Diameter of ring in mm
wireDiameter = 2;
// Aspect ratio of the ring (Inner diameter/Wire diameter)
// Ring AR range for JPL is 2.7-3.1 Outside this range, the rings will either be fused together or the weave will not stay correctly formed.
ringAR = 2.8;

// Smoothness factor (larger = smoother, but longer to generate stl)
smoothness = 40;

union()
{
	for (i = [1:numRings])
	{
		rotate([120*(i%3),0,0])
		translate([i*(wireDiameter*ringAR+wireDiameter)/3,0,0])
		rotate([0,-asin(1/(ringAR+1)),0])
		ring(wireDiameter, ringAR);
	}

Okay, I'm looking for an OpenSCAD design for a customizable organizer, similar to what I've been experimenting with.

Here's what I need:

I want to be able to specify the number of rows and columns of the organizer. Each cell in the organizer should be a rectangular prism with rounded corners. I need to control:

*   **`numberOfColumns`**: The number of columns in the organizer.
*   **`numberOfRows`**: The number of rows in the organizer.
*   **`singleBoxWidth`**: The width of a single cell, *excluding* any wall thickness.
*   **`singleBoxHeight`**: The height of a single cell, *excluding* any wall thickness.
*   **`baseHeight`**: The height of the base of the entire organizer, basically how thick the bottom is.
*  **`boxHeight`**: The height of the cell walls. The overall height of a cell will be `baseHeight + boxHeight`.
*   **`internalWallThickness`**: The thickness of the walls separating individual cells.
*   **`externalWallThickness`**: The thickness of the outer walls of the entire organizer.
*   **`internalRadius`**: The radius of the rounded corners of each cell.
*   **`quality`**: A setting for the level of detail in rendering the round corners (using `$fn`).

I'd like a single module, probably called `organizer()`, which generates the entire structure.  The core should be a solid box and the interior cells should be hollowed out. Each cell should be identical in size and shape.

Essentially, it's a grid of rounded rectangular boxes within a larger rounded rectangular container.

I need an OpenSCAD file with all of this implemented. I would prefer no explicit use of `hull()`, since it can be computationally expensive, but the same geometry is fine. I'm fine with the use of the `translate()` module.

[Assistant]
round_organizer.scad:
```
numberOfColumns = 5;
numberOfRows = 3;

singleBoxWidth = 30;
singleBoxHeight = 30;

baseHeight = 3;
boxHeight = 30;

internalWallThickness = 3;
externalWallThickness = 3;

internalRadius = 5;
quality=30; // [10:60]

// ignore
$fn=quality;

module roundbox(r,wi,he,dz) {
	hull()
	{
		cube([wi, he, dz]);
		translate([0,0,0])
			cylinder(r=r, h=dz);
		translate([wi, 0, 0])
			cylinder(r=r, h=dz);
		translate([wi, he, 0])
			cylinder(r=r, h=dz);
		translate([0, he, 0])
			cylinder(r=r, h=dz);
	}

}

module organizer() {
	difference() {
	   roundbox(externalWallThickness, numberOfColumns*singleBoxWidth+(numberOfColumns-1)*internalWallThickness, numberOfRows*singleBoxHeight+(numberOfRows-1)*internalWallThickness, baseHeight+boxHeight);
	   for (y=[0:numberOfRows-1])
			for (x=[0:numberOfColumns-1]) {
				translate([(internalWallThickness+singleBoxWidth)*x, (internalWallThickness+singleBoxHeight)*y, baseHeight]) {
				translate([internalRadius,internalRadius,0])
					roundbox(internalRadius,singleBoxWidth-2*internalRadius,singleBoxHeight-2*internalRadius, boxHeight+1);
			}
		}
	}
}

organizer();

Okay, I'm looking for help designing a customizable finger socket and fingertip for a prosthetic device. I've seen the design from e-NABLE (I think the file was called "Socket_tip_update.scad"), and I'd like to create something similar, but I want to make it parametric and easier to tweak. I need to be able to adjust all of the critical dimensions. I’d like to be able to select if I am viewing the socket or the tip from a variable.

Here are the key features I need:

**Finger Socket:**

*   **Interior Diameter (A):**  This is the diameter of the hole that fits over the finger stump.  I need to be able to set this value.
*   **Socket Depth (B):** The depth of the socket. This value must be less than the socket's exterior length.
*   **Exterior Length (C):** The total length of the socket piece.
*   **General shape:** A mostly cylindrical shape, with some rounding on the exterior edge at the open end to make it more comfortable.
*   **Linkage:** I need a mechanism to attach the socket to the rest of the finger. There should be a central area with a cylinder for an axel. It should also have blocks for stop-motion and ways to tie off a bungee cord and cable.
*   **Cable and Bungee Channels:**  There needs to be pathways for both a cable and a bungee cord to pass through the socket.  These channels need to be wide enough to accommodate the cords.
*   **Supporting Beams:** There should be some reinforcing bars around the exterior of the base of the socket, at 0, 45, and -45 degrees of rotation, to increase stability.
*   **Screw/Pin Recesses:** At the base of the exterior I will need to include some cylinderical cutouts for alignment pins or screws.

**Finger Tip:**

*   **Length (D):** The overall length of the artificial fingertip.
*   **Female End:** The end that will attach to the socket needs to have a specific profile with a cylindrical recess and a place to mount and hold an axel. It should also have the same "stopping" blocks as the socket to prevent unwanted rotation.
*   **Finger Pad:** The fingertip should have a rounded finger pad at the end. This pad should have a fairly complex shape that uses some angled cylinders that extend from the main body and are smoothed by a hull.
*  **Bungee and Cable Channels:** Similar to the socket, the finger tip needs channels for a cable and a bungee cord. There should also be small cubical blocks at the end of the channels to tie the cords off to.
*   **Axel Hole:**  There needs to be a through-hole for an axel to allow rotation in the female end.
*   **Flat Top:** A flat section at the top of the tip to add more stability to the form.
*   **Angled Edges:** Some angled edges to add a more ergonomic form.
*    **Snap-Pin Recesses:** Small recesses at the base to allow a pin or screw to mount the tip to the socket.

**General Requirements:**

*   **Parametric Design:** I need to be able to change all of the above measurements as variables in the OpenSCAD file.
*   **View Selection:** I need a variable to select if I am viewing the first part (socket) or the second part (tip)
*   **Units:** All measurements should be in millimeters.
*   **Libraries:** I would prefer not to use external libraries, but if it's required to simplify a complex shape, I'm okay with using the BOSL library.
*   **$fn:** It would be good to set a low default $fn and a comment to remind the user to increase it for final printing.

Could you please generate an OpenSCAD file that does this?

Okay, I need a new OpenSCAD file designed, based on an existing design I have. I've got a file called `back_of_hand_guide.scad` that's meant to be part of a partial finger prosthetic. It's a cable guide that sits on the back of the hand.

Here's what the current design does:

*   **Base Shape:** It starts with a flat, roughly trapezoidal shape that's extruded to a thickness of 2mm. The shape is defined by a polygon with points dependent on a `kw` parameter, which stands for knuckle width. This polygon essentially has a wider top section and then tapers down to a narrower base.
*   **Webbing Spaces:** It cuts out three cylindrical voids near the top edge to allow for webbing. These cylinders are scaled to be long along one axis, effectively making them more like slots, and are positioned at specific offsets relative to the center.
*   **Strap Mount Holes:** There are three small cylinder cutouts for mounting straps; one at the center and two others mirrored on the X axis.
*   **Knuckle Guides:** There are sets of small cylinders that protrude out, representing guides, for the knuckles. They are placed in pairs and have a larger diameter cylinder that is cut to a lesser depth than the smaller diameter cylinder, which creates a lip around each guide post. These pairs of cylinders are repeated at several different X coordinates near the top edge, all with the same height and diameters.
*   **Wrist Guides:** Identical to the knuckle guides, but mirrored across the X-axis, offset in the Y axis and using a smaller set of X coordinates.

I want the new design to be parametric so that I can easily adjust it for different hand sizes. Here's a list of parameters I'd like to control, in addition to the existing `kw`:

1.  **`kw` (Knuckle Width):** (Existing) This is the main width of the piece and it impacts the base polygon. I want to keep it as the primary sizing variable.
2.  **`base_thickness`:** The extrusion height of the base shape. Currently it's 2mm, I would like to be able to change this.
3.  **`webbing_offset_x`:** A parameter that controls the horizontal offset from the center for the webbing slots, currently `kw/3.5`.
4.  **`webbing_offset_y`:** A parameter that controls the vertical offset from the center for the webbing slots, currently 40.
5.   **`webbing_slot_radius`:** The radius of the cylinder used to make the webbing slots, currently `kw/16`.
6. **`webbing_slot_length_mult`**: A multiplier value that increases/decreases the long side of the webbing slots, currently 4
7.  **`strap_hole_radius`:** The radius of the holes for the strap mounts, currently 2mm.
8.  **`knuckle_guide_offset_x`:**  An array of X offsets for the knuckle guide pairs, currently `[kw/2.4, kw/7, -kw/7, -kw/2.4]`.
9. **`wrist_guide_offset_x`**: An array of X offsets for the wrist guide pairs, currently `[(kw/2.4)/2, (kw/7)/2, (-kw/7)/2, (-kw/2.4)/2]`.
10. **`guide_offset_y`**: A shared Y offset for both the knuckle guides and the wrist guides, currently `kw/2-2` for the knuckle guides and `-kw/2+2` for the wrist guides.
11. **`guide_offset_z`**: A shared Z offset for both the knuckle guides and the wrist guides, currently 1.75.
12. **`guide_outer_radius`:** The radius of the outer, larger cylinder in the guide pairs, currently 2.5mm.
13. **`guide_inner_radius`:** The radius of the inner, smaller cylinder in the guide pairs, currently 1.25mm.
14. **`guide_outer_height`:** The height of the outer, larger cylinder in the guide pairs, currently 3mm.
15. **`guide_inner_height`:** The height of the inner, smaller cylinder in the guide pairs, currently 5mm.

Also, make sure the code is well-commented and easy to understand. I think that's everything. Can you generate the OpenSCAD file for me? I do not need any library files.

Okay, I need a little help designing a phone/tablet holder that attaches to a PlayStation Sixaxis controller. I've been trying to make one based on a design I found, but I'd like it to be more parametric and robust. Here's what I'm thinking:

**Core Functionality:**

The basic idea is a clip that securely grips a Sixaxis controller, and then a second clip (or set of clips) extending from that which holds a phone or tablet. The phone/tablet clip should be adjustable in angle and distance from the controller. I want to be able to easily change the dimensions to fit different phones or tablets, even ones with cases on them.

**Sixaxis Clip:**

*   The Sixaxis clip should essentially be a 'U' shaped bracket that wraps around the controller.
*   I'd need parameters for:
    *   `six_clip_thick`: The overall thickness of the bracket material.
    *   `six_clip_w`: The width of the bracket that runs along the controller's length.
    *   `six_clip_d`: The thickness (depth) of the Sixaxis controller itself.
    *   `six_clip_db`: How much of the controller the clip covers on the 'front' side, extending down the side.
    *   `six_clip_l`: The length of the controller.
    *   `six_t_overlap`: How much the top of the clip overlaps the top of the controller (for secure hold).

**Phone/Tablet Clip:**

*   The phone/tablet clip should attach to the side of the sixaxis clip, and extend outwards.
*   Ideally, it would have two arms with a small overlap at the end that the phone/tablet fits into.
*  I'd need parameters for:
    *   `phone_clip_overlap`: The extra length of the clip at the ends that hold the phone on.
    *   `phone_clip_d`: The overall thickness/depth of the phone/tablet.
    *   `phone_clip_l`: The length or width of the phone/tablet (depending on orientation).
    *   `phone_clip_ang`: The angle of the phone clip relative to the sixaxis clip.
    *   `phone_clip_extra`: The distance the phone clip extends out away from the sixaxis clip.
    *   `phone_clip_attach`: The location (height) of the attachment point on the side of the Sixaxis clip.

**Improvements over Existing Design:**

*   I'd like the phone clips to be a little more robust. The arms in the existing model are a bit thin and could potentially snap.
*  It would be nice if there was some way to have more parameters to control the curvature of the corners in a more user friendly way than just messing with the width and thickness of the arms.
*  The phone attachment should be a little more secure, maybe a lip or some sort of flexible catch.
*   I think having a library of functions for adding fillets and chamfers to the edges would be really helpful.

**Libraries:**

I think it would be helpful to use the BOSL2 library to help with the fillets, chamfers, and general construction.

**Output:**

I need a single OpenSCAD file that includes all the above functionality, using parameters and BOSL2 to make the model more robust. I'd also like to see a fully rendered model to make sure it's coming together correctly.

Okay, I'm trying to design a chainmaille weave called "Box Chain" and I'd like to create a parametric OpenSCAD file that I can use to generate different lengths and ring sizes. I have a basic SCAD file that gets me close, but it's not very flexible, and I'd like to have more control over the design.

Here's what I'm looking for:

*   **Variable Length:** I want to be able to specify the number of segments (the linked pairs of rings), allowing me to easily create chains of different lengths.
*   **Ring Parameters:** The design uses rings that are characterized by the following:
    *   `wireDiameter`: The thickness of the wire used to form the rings.
    *   `ringAR`: The aspect ratio of the ring (inner diameter / wire diameter). I know this ratio needs to be above 3.8, but ideally above 4.8 if I want the rings to maintain a square cross section. Fusing can begin around 4.0, so the script needs to handle that scenario too.
*   **Angled Ring Pairs:** The fundamental element of the Box Chain is two pairs of rings, angled to interlock at a certain degree, and arranged in a vertical stack, with one pair rotated 180 degrees around the Y-axis. The angle between the linked pairs, initially at 32.5 degrees, should be parametric. When the AR falls below 4.8, the rings within each pair should be angled at 32.5 - 10 degrees and 32.5 + 10 degrees, respectively, and translated to prevent fusion.
*   **Smoothness Control:** I'd like to be able to control the smoothness of the generated rings using a variable. This is particularly important when generating an STL model.
*  **No Fusing:** I'd like a non-fusing design. My current script begins to fuse the rings at around AR values of 4.0.

I'm attaching my current attempt, `Box_Customizer.scad`, so you can see what I've been working with, although I know it has some limitations.

Ideally, the final SCAD file should define modules like:

*   `angledPair(angle)`: To generate a pair of angled rings.
*   `ring(wd, ar)`: To generate an individual ring given the wire diameter and aspect ratio.
*   A top-level module or section that assembles the chain based on the `numSegments` parameter.

I'm hoping you can help me build a more robust, parametric OpenSCAD file, using the parameters specified above, that allows me to easily adjust the chain's length, ring size and smoothness. Additionally, it should handle fusing scenarios, so that the chain is non-fusing. Also, I'm not sure which OpenSCAD library you'd recommend, but feel free to use any library that simplifies this design.

// Ring AR range for Box is greater than 3.8. However, it does not maintain a square cross section below an AR of 4.8. Fusing from script begins around an AR of 4.0.
ringAR = 4.8;

// Smoothness factor (larger = smoother, but longer to generate stl)
smoothness = 40;

Okay, I need help designing a system for using standard 2-liter bottles with my Filastruder pellet extruder. I've got a design already in OpenSCAD, but it's a bit clunky and I want it to be more parametric so it's easier to adapt to other bottle sizes or extruder setups.

Here's the basic idea:

I need a system that has these parts:

1.  **Bottle Neck Adapter:** This part screws onto a standard 2-liter bottle (or similar bottles using the same cap thread). It needs to fit snugly but also screw on easily. It needs to account for thread pitch and the difference between the inner and outer diameter of the bottle neck.

2.  **Funnel:** This part screws onto the bottle and has a wide mouth for pouring pellets in. It should transition from the bottle thread to the larger opening of the funnel smoothly.

3.  **Filastruder Hopper Adapter:** This part screws onto the bottle and fits into the Filastruder's hopper. It needs to have a hole to let pellets through. I want both a straight version and an angled version to work with Filastruders in different orientations. The angled version should have about a 45-degree bend.

4.  **Comb/Blocker:** A small piece that inserts into the hopper adapter to stop the pellets from flowing while the bottle is being mounted or unmounted. This should have holes to make sure it doesn't block airflow.

5.  **Cap:** A simple cap to seal the bottle so it can be stored with plastic pellets in it.

I'd like these parameters to be adjustable:

*   **Bottle Parameters:**
    *   `bottleID`: Inside diameter of the bottle neck.
    *   `bottleIR`: Inside radius of the bottle neck.
    *   `bottleOD`: Outside diameter of the bottle neck.
    *   `bottlePitch`: Pitch of the bottle thread.
    *   `bottleHeight`: Height of the bottle neck threading.
    *   `bottleAngle`: Angle of the bottle thread (usually just a slight slope)
    *   `threadLen`: length of threads in neck.
    *  `bottleNeckID`: diameter of the inside of the bottle neck before the threads.

*   **Holder Parameters:**
    *   `holderOD`:  Outside diameter of the 'holder' part of the adapter
    *   `holderOR`: Outside radius of the holder

*   **Funnel Parameters:**
    *   `funnelOD`: Outside diameter of the funnel opening.
    *   `funnelOR`: Outside radius of the funnel opening.
    *   `funnelWall`: Thickness of the funnel walls.
    *   `funnelIR`: Inside radius of the funnel where it meets the bottle neck.
     *   `funnelRim`: Rim thickness.

*   **Filastruder Hopper Parameters:**
    *   `filaX`: Width of the Filastruder hopper opening.
    *   `filaY`: Depth of the Filastruder hopper opening.
    *   `filaDepth`: Height of the Filastruder hopper adapter section.
    *   `filaHoleD`: Diameter of the hole that allows pellets to flow.
    *   `filaHoleR`: Radius of the hole.
    *   `filaGap`: Spacing between where the bottle threads and the hopper section of the part begin.

*   **Comb Parameters:**
    *   `otherD`: Diameter of the pins in the comb.
    *   `otherR`: Radius of the pins in the comb.

*   **Clearance Parameter:**
    *   `clearance`: A small value to add to dimensions to account for printing tolerances.

*   **General Parameters:**
    *   `$fn`: For curvature smoothness.

I'm thinking it would be useful to define helper modules like:

*   `bottleNeck()`: creates the bottle neck threads and shape.
*   `bottleHolder()`: creates a simple cylinder that fits over the bottle neck threads.
*  `funnel()`: creates the entire funnel part.
*   `FilaBottle()`:  creates the straight adapter for the filastruder.
*  `FilaAngledBottle()`: creates the angled version of the filastruder adapter.
*  `filaComb()`: creates the comb piece
*  `filaCombHole()`: creates the holes for the comb.
*  `filaCap()`: creates a simple cap for the bottle.

I'd also like the system to be flexible enough to be able to show just one part, or all of the parts, based on a 'part' parameter.

Also, can we use the `linear_extrude()` for the threads to make them more accurate to the pitch?

Could you create a parametric OpenSCAD file with these parts, parameters, and modules? Please use a library if possible, but I don't want to have to install anything beyond the default libraries in OpenSCAD.

Okay, I need a parametric OpenSCAD design for a linear actuator enclosure. It should hold a linear actuator slider and a motor, with a connecting rib between them.

Here are the specific requirements:

*   **Core Components:**
    *   **Linear Actuator Slider Housing:** The slider housing needs to have a cylindrical outer part with a fixed diameter and a smaller inner diameter, with recessed areas for bearings at the top and bottom. The inner diameter should be sized for the actual slider to move within, the outer shell around it will support the bearings and mounting. The outer shell should be sized to have a wall of roughly 2mm.
    *  **Motor Housing:** The motor housing needs to be a cylinder with a through hole and a cutout on one side.  It'll be mounted on a flat surface and have two fastening walls on the left and right and a single bolt hole for mounting to this surface.
    *   **Joining Rib:**  A connecting rib should join the slider housing and the motor housing.

*   **Parameters:** I need to be able to easily adjust these parameters:
    *   `dist`: The distance between the center axes of the linear actuator slider and the motor housing (default 15mm).
    *   `rib_thickness`: The thickness of the joining rib (default 5mm).
    *   `slider_outer_diam`: Outer diameter of the linear actuator slider housing (default 16mm).
    *   `slider_inner_diam`: Inner diameter of the linear actuator slider (default 6mm).
    * `slider_bearing_diam`: diameter of the bearing housings for the linear actuator slider (default 12mm)
    *   `motor_outer_diam`: Outer diameter of the motor housing (default 13mm).
    *   `motor_inner_diam`: Inner diameter of the motor housing (default 10mm).
    *   `bearing_housing_height`: Height of the bearing housings on both ends of the slider (default 4mm)
    *    `fastening_wall_width`: The width of the walls that will attach the motor to the surface (default 2mm)
    *    `fastening_wall_length`: The length of the walls that will attach the motor to the surface (default 5mm)

*   **Fixed Values:**
    *   The height of the bearing housing recess is fixed (4mm).
    *   The bolt hole diameter is fixed (2.2mm).
    *   The bolt hole spacing is fixed in relation to the motor housing walls.
    *   The linear slider should have an exterior support shell which is roughly 2mm thick

*   **Additional Notes:**
    *   The motor housing needs a cutout on one side to accommodate wiring.
    *   There needs to be a hinge point that is perpendicular to the other two axes. This can simply be a cylinder with a hole through it
    * The motor is held in place with the flat mounting surface, the two walls to the left and right of the motor and by a single bolt passing through the flat surface.

*   **Output:** I'd like a single `.scad` file that I can use directly. It would be great if it is well-commented so that I can understand what everything does. I don't need any special libraries like MCAD, BOSL, or BOSL2 for this.

Essentially, I want a configurable enclosure that can be adapted to different sized linear actuators and motor combinations, while also maintaining the mounting points.

Can you generate the code for this?

LINEAR_ACTUATOR_ENCLOSURE_v2.scad:
```
$fn = (100 * 1);

//distance between axis in mm
dist = 15;

//joint rib thickness in mm =
rib_thickness = 5; //[2:10]

difference() {
	union() {
		difference() {
			cylinder(h = 25, r = 8); //linear actuator slider outer diam
			translate([0, 0, -2]) cylinder(h = 7, r = 6); //bottom bearing housing
			cylinder(h = 40, r = 3); //linear actuator slider inner diam
			translate([0, 0, 21]) cylinder(h = 6, r = 6); //top bearing housing
		}
		translate([dist, 0, 0]) {
			difference() {
				cylinder(h = 25, r = 6.5); //motor housing outer diam
				translate([0, 0, -2]) cylinder(h = 50, r = 5); //motor housing inner diam
				translate([0, -1, -2]) cube(size = [25, 2, 40], center = false);  //motor housing cut out
			}
			difference() {
				translate([-(dist / 2), 0, 12.5]) cube(size = [((dist / 2) + 15),rib_thickness,25], center = true); //join rib
				translate([-dist, 0, -2]) cylinder(h = 50, r = 6); //join rib substraction from linear act slider
				translate([0, 0, -2])cylinder(h = 60, r = 5); //join rib substraction from motor
			}

			difference() {
				union() {
					translate([5, 1, 0]) cube(size = [5, 2, 25], center = false);  //right wall to fasten the motor
					translate([5, -3, 0]) cube(size = [5, 2, 25], center = false); //left wall to fasten the motor
				}
				rotate([90, 0, 0]) translate([7.5, 12.5, 0]) cylinder(h = 17, r = 1.1, center = true); // hole for the bolt

			}
		}

	rotate([90, 0, 0]) translate([6, 12.5, 0]) cylinder(h = 17, r = 2.5, center = true); //rotation hinge
	}
	rotate([90, 0, 0]) translate([6, 12.5, 0]) cylinder(h = 30, r = 1.5, center = true); //hole of the rotation hinge
}
