Hey, I'm looking to get a customizable caliper designed in OpenSCAD. I've got some specific ideas and features I'd like included.

First, the basic design should consist of two main parts: a main body (or ruler portion) and a sliding piece. The main body should have a trapezoidal profile, making it wider at the base. I want to be able to specify the length, width, and thickness of the main measuring section. I'd also like to be able to set the distance between major tick marks (like centimeters or inches), a multiplier for those major tick marks for labeling, and the number of minor tick marks between the major ones. The edge thickness of the sliding portion, above and below the ruler piece, needs to be adjustable. And of course, I need a way to control the clearance between the sliding piece and the ruler piece.

I need a few optional features too. First, I’d like to have an option for bold letters for the tick mark labels. I want to control the boldness of these letters. Also, I'd like an optional hole that I can enable/disable and specify the size of (to hang the caliper), and finally the ability to add a brim around the parts for better bed adhesion on my 3D printer, with the brim height as a setting. The caliper should have tick marks on the main body and the sliding piece. For the main body tick marks, I want to control the thickness of those marks, and I want to control the length of the marks. The length of the minor tick marks should be different from the major tick marks, as is standard, and I'd like the mark length to vary depending on it's position. I think that would require a function, though I'm not sure. On the sliding portion, the marks need to correspond to the main scale, but only a short portion of the scale needs to be represented. I'd like to control how many major scales the sliding piece encompasses.

Finally, I'd like an offset parameter so that I can compensate for filament width, because some printers have a tendency to print thicker than specified. I'm thinking that should be applied to the main body and the sliding portion.

I think that's everything. I'd like the design to use the `write/Write.scad` library to generate the text for the scale. Let me know if you have any questions.

Hey, I'm trying to design some hooks that will slide onto a metal wine rack to hold tea cups. I have some ideas, but I'm not very good at OpenSCAD so I'd like some help.

Basically, the hook should have a top bar that slides onto the wine rack, a middle hook part, and a kind of hoop at the end for hanging the cups. I'd like to make it parametric so I can adjust it later.

The top bar should have a rectangular shape, with a small "lip" at the sides that fit over the edges of the rack. Let's call these: `latchWidth` for the thickness of the top bar, `latchLength` for its length, and `latchHeight` for its height.  The "lip" part should be generated from cubes and should be set as `tabsLength` and `tabsThickness`.

The middle hook should just be a rectangular bar, with parameters `hookLength` and `hookWidth`. This bar should extend from the side of the top bar. The `hookHeight` should be equal to `latchHeight`.

Finally, the end of the hook should have a hoop shape. The inner diameter of the hoop should be driven by a multiple of `hookWidth`, so let's call that multiple `openingMul`. The actual opening would be derived as `opening=hookWidth*openingMul`. The "hoop" should actually be a circle with the aforementioned opening cut from it, with a small rectangle below the opening that helps the cups rest. The actual outer diameter of the hoop will need to be calculated from the `opening`.

Could you generate an OpenSCAD file with these parameters? It'd be great if I could adjust all those values at the beginning of the file. I think I can manage putting multiple hooks together in the same file later, just need to start with one good one for now. Also, please do not use libraries, I prefer the code as primitive as possible.

[Assistant]
kitchenhook.scad:

latchLength=114;
latchHeight=10;

hookLength=67;
hookWidth=6;

//Hoop

//Tabs
tabsLength=15;
tabsThickness=5;

opening=hookWidth*openingMul;
hookHeight=latchHeight;

union(){
    cube([latchWidth,latchLength,latchHeight],center=true);
    translate([latchWidth+((tabsLength-latchWidth)/2),0,0]){
    difference(){
        cube([tabsLength,latchLength,latchHeight],center=true);
        cube([tabsLength,latchLength-tabsThickness,latchHeight],center=true);
    }}
    translate([(hookLength/2)+(latchWidth/2),0,0]){
        cube([hookLength,hookWidth,hookHeight],center=true);
    }
}
translate([(hookLength+(latchWidth/2)),hookWidth*(openingMul-1)+(hookWidth/2),-(hookHeight/2)]){
    linear_extrude(height=latchHeight){
    union(){
    difference(){
        circle(opening);

Hey, I'm looking to get a custom Cloudshell top for my Odroid XU4 designed, with some specific cuts for easier 3D printing. I've got some ideas on how I want it broken up but need it to be parametric so I can tweak things later. I'm also planning on using puzzle cut joints, which I've seen a few libraries for, to connect the pieces together, and I need to be able to adjust the kerf of those joints too, so hopefully the library you use supports that. I plan on printing it, so having the ability to tune the tightness of the fit is important.

Here's the basic idea:

The top is based on the Cloudshell top for the Odroid XU4, you can find the basic shape on the official Hardkernel site (http://odroid.com/dokuwiki/doku.php?id=en:xu4_cloudshell). I plan on importing this shape from a DXF.

I need the design to include the following features:
- The base shape should be loaded from a "Cloudshell.top.dxf" file.
- It should be cut into four pieces using puzzle cuts, so it can fit on smaller printers and be assembled later.
- The cut locations on the X-axis should be adjustable via a parameter, initially I'd like to try three cuts at x=[-26,26 , -95] relative to the center of the part on the X axis.
- The cut locations on the Y-axis should also be adjustable via a parameter; initially try four cuts y=[-62,-7, 20, 40] relative to the center on the Y axis.
- The size of the puzzle cuts should be a parameter, start at 4 mm.
- The kerf (gap between pieces) should be a parameter to adjust the fit of the puzzle pieces, and should support a negative value for a tighter fit; I plan to test with a -0.1mm kerf.
- Each of the four parts should have puzzle cuts on its edges, male cuts on two sides and female on the other two, so it can be interlocked with the other pieces when assembled.

So, basically, I need an OpenSCAD file or set of files that imports this DXF, does the puzzle cuts as specified, and parameterizes the cut locations, size, and kerf of the puzzle joints. For the puzzle cut library, I know there are libraries on Thingiverse, but I don't have a particular preference, I'll leave it up to you to pick one that works well with my needs. I don't really have any other specific libraries I want to use, just whatever is necessary to get this working. I'd really prefer if it was modular and I could just import it to do the cutting parts and then pass in the correct parameters to create the various parts of the cut up top for the 3d printer. I'd like to be able to just call a module that does the cutting of one of the four pieces for example. I'm looking forward to seeing what you come up with!

[Assistant]
Cloudshell.top.scad:
```
// Cloudshell top cover mod
include <puzzlecutlib.scad>

stampSize = [500,500,100];//size of cutting stamp (should cover 1/2 of object)

cutSize = 4;	//size of the puzzle cuts

xCut1 = [-26,26 , -95];   //locations of puzzle cuts relative to X axis center
yCut1 = [-62,-7, 20, 40];	   //for Y axis

kerf = -0.1;	//supports +/- numbers (greater value = tighter fit)
				//using a small negative number may be useful to assure easy fit for 3d printing
				//using positive values useful for lasercutting
				//negative values can also help visualize cuts without seperating pieces

//cutInTwo();	//cuts in two along y axis

module drawCover()
{
    translate([60, 80, 0])

Hey, I'm looking to create a fully parametric piano hinge in OpenSCAD. I've seen a design that does something similar, but I want to make sure my version is solid and flexible, and uses a more modern library structure. I’d like to be able to control a bunch of things.

Specifically, I need to be able to define:

*   **Number of Tabs:** The total number of hinge segments.
*   **Tab Spacing (Tolerance):** The space between each tab, which also acts as the tolerance between hinge parts.
*   **Tab Length:** The length of each individual tab.
*   **Outer Radius:** The radius of the outer cylinder of the hinge.
*   **Outer Thickness:** The thickness of the outer cylinder wall.
*   **Inner Radius:** The radius of the inner cylinder of the hinge.
*  **Tassel Thickness:** The thickness of the tab that extends out from the main hinge cylinder.
*   **Tassel Length:** The length of the tab extending out of the hinge cylinder.
*   **United Tabs Option:** A boolean or flag (0 or 1) to make it so all the tabs are either linked together into one long piece or are separate, independent tabs.

The hinge should consist of alternating mirrored hinge segments, and each tab should be centered vertically on its hinge part. The first and last hinge segments should be slightly different, they need to have a connecting "cap".

I want the code to be well-organized, and if it's reasonable, can you please organize it using the BOSL2 library? I'm particularly interested in having the core hinge part be a modular component, and use BOSL2's `linear_extrude` rather than its `rotate_extrude`. I would also like to include good comments and descriptive variable names to make it easy to understand. Finally, I'd prefer the "unite tabs" option to be handled through a different module, rather than an if statement in the main hinge module if it makes sense. If we use this unite module, the united tabs should go across the full length of the hinge and have the same thickness as the individual tabs.

Can you help me generate this?

Hey there, I'm looking for a way to design a parametric camera lens cap holder that attaches to a camera strap. I've seen a few designs, but I want something I can really customize.

Specifically, I'd like the design to have the following features:

*   A cylindrical base that will hold the lens cap. This should have a customizable height, and the hole for the lens cap should also be customizable, both in width and height. I also want to be able to add a small angle to the bottom of the hole to help hold the cap in place. The outer wall thickness should be configurable. And, of course, the base needs a hole in the bottom to minimize material use.

*   A strap mount that uses two offset cylinders to hold the camera strap. The gap between the two cylinders should be customizable, as should the width of the cylinders and their thickness. The mount should be robust enough to hold the cap securely without wobbling, and should be able to fit around the camera's neck strap. I don't want it to slide around.

*   I need to be able to define the number of facets for all cylinders.

*   I want to be able to configure the tolerance for the lens cap hole; I'll need a little extra space for printing tolerances.

I think it would also be helpful to define some parameters for the design:

*   `definition`:  The number of facets to use for cylinders.
*   `baseheight`: The height of the base of the holder.
*   `basewidth`: The amount of plastic around the lens cap (the thickness of the cylinder wall).
*   `basehole`: The width of the hole at the bottom of the base.
*  `capwidth`: The width of the lens cap.
*  `captilt`: The width to add to the bottom of the lens cap hole to make an angle.
*  `capheight`: The height of the cutout for the lens cap.
*  `captolerance`: The tolerance for the lens cap hole.
*  `beltlength`: The gap between the strap holder and the base of the cap holder.
*  `beltwidth`: The width of the camera strap.
*  `beltheight`: The height of the strap holder.
*  `beltthickness`: The thickness of the strap holder.

I'd like the OpenSCAD file(s) to use these variables so that I can change them easily. I don't have a preference for how the project is structured, as long as it's easy to understand and customize. I would also like the code to not rely on any external libraries or modules (no MCAD, BOSL, etc).

I'm looking to create a customizable hanger for my sleep apnea mask that will attach to the top of my bed's headboard. I'd like to be able to adjust the dimensions to fit different headboard thicknesses and mask hose diameters.

The basic design should consist of a rectangular base that sits on top of the headboard, a vertical section that extends down from the back of the base, and a curved hanger that projects out from the vertical section to hold the hose.

Specifically, I'm thinking the design should have these parameters:

*   `BackLength`: The depth of the base that sits on the headboard.
*   `HBWidth`: The width of the horizontal part of the base that rests on the headboard. This will need to be adjustable to fit various thicknesses of headboards.
*   `HoseDiameter`: The diameter of the mask hose, which will determine the size of the curved portion of the hanger.
*   `FrontLength`: The vertical length of the support from the top of the headboard to the bottom where the hanger starts.
*  `Width`: The width of the hanger, and all the support parts.
*   `HangerThickenss`: The thickness of all the parts, including the base, the vertical support, and the hanger.

The hanger itself should be a cylinder with a cutout to allow the hose to slip in, but should not be a complete ring. The design should include a small lip at the opening of the cylinder to hold the hose securely. I think it's important to include a short support cube to ensure the curved part of the hanger doesn't rotate, and a small supporting piece to provide more strength to the cylinder hanger.

Could you generate an OpenSCAD file (or set of files) that allows me to customize all of these parameters? I'm not familiar with any specific libraries, so if there are any that would be useful, please feel free to incorporate them.

[User] I'd like a customizable heart design for OpenSCAD. I need to be able to specify the text that's cut out from the heart shape. I need to be able to put up to three lines of text, but the user should be able to specify if they want to show just one, two, or all three lines. I also need to be able to control the size of the heart and the vertical position of the text relative to the heart. I'd also like for it to be in red, by default. I'd prefer that the text use the "Liberation Sans:style=Bold" font and be centered. I'd like to control the line height of the text, the size of the font, and the extrusion height of the text as well as the extrusion height of the heart. I don't need to adjust the position of the heart. Can you help with that?

I'd like to design a customizable box with a lid in OpenSCAD. It should be a rectangular box with rounded corners. I want to be able to specify the overall height, length, and width of the box, as well as the radius of the rounded corners.

The box should have walls of a certain thickness, and a floor of a specified thickness. Additionally, I want to be able to add internal dividers to create sections within the box. I'd like to control the number of sections in both the length and width directions, and also specify the height of these sections. The internal walls should have their own thickness, which might be different from the outer wall thickness.

The lid should fit on top of the box, with a small tolerance so it's not too tight. I need to be able to specify the thickness of the lid's top, and the overall height of the lid.

I want the code to generate both the box and the lid. It would also be nice if you could generate a warning if the corner radius is less than 2.

Here's a breakdown of the parameters I'd like to control:

*   **Overall Box Dimensions:**
    *   `height`: Overall height of the box.
    *   `length`: Overall length of the box.
    *   `width`: Overall width of the box.
*   **Corner Details:**
    *   `cornerrad`: Radius of the rounded corners (minimum 2).
*   **Wall and Floor Thickness:**
    *   `outwalls`: Thickness of the outer walls.
    *   `thickness`: Thickness of the box floor.
*   **Section Details:**
    *   `sectionsl`: Number of sections along the length.
    *   `sectionsw`: Number of sections along the width.
    *  `sectionsh`: Height of internal divider sections.
    *   `inwalls`: Thickness of the internal walls.
*   **Lid Details:**
    *   `tol`: Tolerance for the lid fit.
    *   `lidthickness`: Thickness of the top of the lid.
    *  `lidheight`: Overall height of the lid.

I'm not using any libraries at this point, so it would be good to keep it simple.

I'd like a customizable slide box generator in OpenSCAD. I need to be able to control the size of the objects that go in the box, how many of those objects there are in each dimension, the spacing between those objects, and the wall thickness of the box itself. I also need to control the gap between the top and bottom pieces to make it a good fit for 3D printing. It needs to generate two separate parts (top and bottom) and both parts combined, with the ability to select which part(s) get rendered.

Specifically, I'd like the following parameters exposed in a customizer interface:

*   **Object size:**  `object_size_x`, `object_size_y`, `object_size_z` (all with range from 0.2 to 60, step 0.2)
*   **Object count:** `object_slots_x`, `object_slots_y`, `object_slots_z` (all with range from 1 to 50, step 1)
*   **Margin between objects:** `object_air_x`, `object_air_y`, `object_air_z` (all with range from 0 to 2, step 0.1)
*   **Wall thickness:** `wall_x`, `wall_y`, `wall_z` (all with range from 0.05 to 3, step 0.05)
*   **Gap between pieces:** `print_space_x`, `print_space_y`, `print_space_z` (all with range from 0.05 to 0.5, step 0.05)
*   **Part selection:** `part` (dropdown with options "top", "bottom", "both")

The top and bottom should have a mating lip/groove, with the groove on the bottom, that will allow them to slide together.

The code should use `$fn=100` for smooth curves. Can you also make sure to use the `minkowski` operation and `truncate_to_z` for the shape and ensure that the inside of the box is hollow? I'd like to be able to use this for relatively large prints, so optimization is important. I expect the design to generate the top and bottom as two distinct pieces, and to render just one or the other based on the part parameter.

Okay, I'm looking to create a custom tile holder for some hex-shaped game tiles, and I'd like it to be parametric. I have some existing code that does the trick for a single container, but I'd like something more flexible and reusable. I think it'd be great if we could generate both the containers and the lids.

Essentially, I need a way to specify the diameter of the hexagon tiles (measured point-to-point across the center), the length of the container (how tall the container should be), and the wall thickness for the container. I'll also need to specify a wall thickness for the lid and potentially a fudge factor to control the lid fit (make it a little looser or tighter).

Specifically, I need:

1.  **Parametric Hexagonal Container:**
    *   Inputs: Tile Diameter, Container Length, Wall Thickness.
    *   Output: An OpenSCAD model of a hexagonal container that will fit the given tiles. There should be some extra room for the tiles, so the internal diameter and length should be slightly larger than the tile's dimensions.

2.  **Parametric Hexagonal Lid:**
    *   Inputs: Wall Thickness of Lid, and Lid Fit Fudge Factor. These parameters, along with the parameters used for container, should result in a lid that fits the previously defined container.
    *   Output: An OpenSCAD model of a hexagonal lid that fits the defined container.

I think it should use the same base parameters as the hex_holder module in the example file I included earlier.

Essentially, I want it to behave like this:
1.  I define container parameters (tile diameter, length, wall thickness).
2.  I can generate a container based on these parameters.
3. I can generate a lid based on parameters and using container's parameters, such that it will fit that particular container.
4. Both lid and container are designed with six sides, like a hexagon, and are cylindrical along the z-axis.

I'm hoping this could be created using pure OpenSCAD (i.e., without any reliance on additional libraries like BOSL).

Could you generate the OpenSCAD code for this?

I need an OpenSCAD design for a customizable tube end cap, like a foot for a stool or chair. I've already got a basic design but want to make it more robust and parametric.

Here's what I need:

The end cap should have a cylindrical body with a hole through the center. It needs to be able to adjust the following parameters:

*   **`inner_diameter`**: This sets the diameter of the central hole that would fit over a tube or leg.
*   **`total_height`**: The overall height of the end cap.
*   **`upper_wall_thickness`**: The thickness of the wall at the top of the cap.
*   **`lower_wall_thickness`**: The thickness of the wall at the base of the cap. This will generally be thicker than the top wall.
*   **`bottom_thickness`**: The thickness of the bottom face of the cap.
*   **`bottom_radius`**: A radius for rounding the bottom outer edge. This creates a nice rounded foot.
*   **`smooth`**: This parameter will allow control of the faceting on the rounded shapes; it will be the number of facets.

I want to make sure it uses a difference function for the inner hole, so that it's a clean subtraction and doesn't cause printing issues. Also, make sure the bottom rounding is done using `rotate_extrude` of a square then subtraction of another rotate_extrude of a circle, as this is a very effective way of achieving the desired rounded base.

Could you please generate the OpenSCAD code for me? I'd prefer just the single .scad file, instead of multiple ones, as I'm not using any libraries.

TubeEndCap.scad:
```
// Hole diameter
inner_diameter = 25;

// Total height
total_height = 10;

// Wall thickness at top
upper_wall_thickness = 1;

// Wall thickness at bottom
lower_wall_thickness = 5;

// Bottom thickness
bottom_thickness = 1;
// Outer rounding radius
bottom_radius = 6;

/* [Hidden] */
smooth = 180;	// Number of facets of rounding cylinder
pad = 0.1;	// Padding to maintain manifold

hole_radius = inner_diameter/2;

difference() {
	union() {
		// Tube cap
		difference() {
			// Outer
            cylinder(total_height,hole_radius+lower_wall_thickness,hole_radius+upper_wall_thickness, center=false,$fn=smooth);
			// Inner (hole)
            translate([0,0,bottom_thickness])
				cylinder(total_height-bottom_thickness+pad,hole_radius,hole_radius,center=false,$fn=smooth);
		}
	}

	// Bottom outer rounding
	difference() {
		rotate_extrude(convexity=10,  $fn = smooth)
			translate([hole_radius+lower_wall_thickness-bottom_radius+pad,-pad,0])
				square(bottom_radius+pad,bottom_radius+pad);
		rotate_extrude(convexity=10,  $fn = smooth)
			translate([hole_radius+lower_wall_thickness-bottom_radius,bottom_radius,0])
				circle(r=bottom_radius,$fn=smooth);
	}
}

Hi! I'm looking to create a custom tray using OpenSCAD, and I have a specific design in mind using a kind of text-based layout approach. I'd like the design to be parametric so I can easily tweak things later.

Here's what I'm thinking:

**Tray Structure:**

*   I need to be able to define the widths of the columns (bins) individually.  For example, I might have a first column that's 50mm wide, a second 25mm, and a third at 25mm. This should be easily adjustable by providing an array of numbers.
*   The row height should be a consistent value that I can specify – let's call it `y_bin_length`.
*   I need to set the depth of the bins, `z_depth`, which will be the same for the entire tray.
*   I also need to define the thickness of the walls separating the bins, `wall_width`.
*   The bottom of the tray should have a thickness as well, which I'll call `bottom_thickness`.

**Tray Layout:**

*   This is where the "text-based" part comes in. I'd like to define the layout of the tray using strings, where:
    *   `|` represents a vertical wall/separation between bins.
    *   `_` represents the bottom edge of a cell/bin within a row.
    *   ` ` (space) represents where a wall should *not* be. So this space merges cells within a row, and merges cells from row to row.
*   Each row should be represented by a string, starting and ending with `|`.
*   The actual tray layout will be a collection of these strings, and the number of strings defines the number of rows.
*   For example, a 3x2 grid where each cell is separated would be something like:
    ```
    |_|_|_|
    |_|_|_|
    ```
*   And if I wanted the last row to be merged, it might look like:
    ```
    |_|_|_|
    |_ _ _|_|
    ```
*   I'd like to be able to specify how many rows I have, and then provide strings for each row that makes up the tray layout.

**Lid Generation:**

*   I also want the option to generate a lid that fits the tray. This should be a separate module or a separate output, since I might not need the lid.
*   For the lid, I'll need parameters like:
    *   `lid_thickness` for the top surface thickness.
    *   `lid_wall_thickness` for the lid's sides.
    *  `lid_depth` for the depth of the lid.
    *   `lid_fudge` which would allow for slight adjustment of the fit (positive to make it looser, negative to make it tighter)
*   The lid should, of course, match the overall dimensions of the tray, including the walls, but will not include the inner dividing walls.
*   It is crucial that the lid parameter matches the tray in the same file, and this should be specified for the lid's dimensions, that is: `_tray_layout` ,  `_x_bin_widths`, `_y_bin_length` , `_z_depth` , `_wall_width` , `_bottom_thickness`.

**Additional Considerations:**

*   I'm aiming for a parametric design, so all of these parameters should be easily adjustable.
*   I'd like to see some examples of how to use the layout strings, as well as output of what the array looks like.
*   Ideally the code would not depend on any external libraries (like MCAD, BOSL, etc).

Could you generate the OpenSCAD code for this?  Let me know if you have any questions.

Hey, I'm looking to create a parametric mount for a Raspberry Pi camera case, specifically to attach it to something else from the bottom. I've been tinkering around with some STLs and some basic SCAD but I think a parametric version would be much more useful for me.

Here's what I'm thinking:

I have a base case for the Raspberry Pi camera already, which I'll just import as an STL. This is the "raspberri_pi_camera_case_front_v0.4.2.STL" from my file system. I need to add a mounting block to the bottom of this case. The mounting block should:

1.  Be a rectangular prism. I want to be able to set its `height`, `width` and `depth`.
2.  Be positioned so it extends below the bottom of the camera case. I will need to adjust how far out it projects from the case (I would like to control with a `mount_offset` parameter).
3.  Include two cylindrical connectors, essentially pegs, located on the bottom face of the block, which match up with a linked piece. These connectors should have a diameter (`connector_diameter`) and a height (`connector_height`). The connectors should be a set distance from each other (`connector_spacing`).
4.  The entire assembly should be configurable via parameters, including parameters like `mount_height`, `mount_width`, `mount_depth`, `mount_offset`, `connector_diameter`, `connector_height` and `connector_spacing`.

I also have a linked part, a simple 30mm long, 2mm wide piece, which can be easily modeled in OpenSCAD. I’m not worried about generating a STL for that part; it's just a small rectangle and I just need the spacing of the connectors on the base to match so the two parts fit together. I imagine you'll handle the peg placement in the `connectors()` function, which will be parameterized.

I'm not concerned about using the "front.stl" or "hinge.stl" files in the mount-bottom.scad example as part of the design, just the camera case STL and the connector idea.

I’d also like the code to be easy to adjust, so parameters should have clearly defined comments. Can you generate the necessary OpenSCAD files to create this parametric mount?

[Assistant]
mount-bottom.scad:
```
import("front.stl");
use <connector.scad>;

$fn=60;

I'm trying to design a cyclone separator cap, and I need help creating the OpenSCAD files. I've got some basic parameters in mind and a general structure, but I need it to be fully parametric.

Here's what I envision:

The cap will have a cylindrical main body, with an intake pipe coming in from the side near the base, and an outlet pipe exiting from the top.  I'd also like to control the thickness of the shell of the main cylinder.

Here are the parameters I want to be able to control:

*   **`res`**:  Resolution for curves.
*   **`intake_d_ext`**: External diameter of the intake pipe at its base.
*  **`intake_sh`**: Thickness of the wall of the intake pipe.
*   **`intake_d_int`**: Internal diameter of the intake pipe at its entrance (where it meets the main body).
*  **`intake_d_int_diff`**: A value that is subtracted from `intake_d_int`  to calculate the inner diameter of the intake pipe at the beginning of the pipe, giving it a slight taper.
*   **`intake_l`**: Length of the intake pipe.
*   **`outlet_d_ext`**: External diameter of the outlet pipe at its base.
*   **`outlet_sh`**: Thickness of the wall of the outlet pipe.
*   **`outlet_d_int`**: Internal diameter of the outlet pipe at its base.
*  **`outlet_d_int_diff`**: A value that is subtracted from `outlet_d_int`  to calculate the inner diameter of the outlet pipe at the end of the pipe, giving it a slight taper.
*   **`outlet_l`**: Length of the outlet pipe.
*   **`top_d`**: Diameter of the main cylindrical body of the cap.
*   **`top_t`**: Thickness of the top face of the main cylindrical body.
*   **`top_h`**: Height of the main cylindrical body.
*  **`shell`**: Thickness of the wall of the main body.

Specifically, I need the following:

1.  **Main Body:** A cylinder with the specified diameter (`top_d`) and height (`top_h`). It should have a shell thickness (`shell`) and a top thickness (`top_t`).
2.  **Intake Pipe:** This pipe should enter the main body from the side. It should have a tapered internal diameter, transitioning from `intake_d_int - intake_d_int_diff` at the beginning of the pipe to `intake_d_int` at its entrance into the main body. The external diameter should remain constant. The placement should be centered on the cylinder, and it should have length `intake_l`. I would like the intake pipe opening on the outer surface to be covered by a scaled sphere for aesthetic reasons.
3.  **Outlet Pipe:** The outlet pipe should exit the main body from the top and be centered at the top. It should also have a tapered internal diameter, transitioning from `outlet_d_int - outlet_d_int_diff` at the beginning of the pipe to `outlet_d_int` at its entrance into the main body. The external diameter should remain constant. The length should be `outlet_l`.

Could you generate the necessary OpenSCAD code for this? Please include comments to explain each part. I don't need to use any libraries.

Hi, I'm looking to get some custom boxes designed for my home automation setup. I've been playing around with a design, but I'd really appreciate it if you could create a parametric OpenSCAD model that's a bit more robust.

Basically, I need a box with a separate lid/cover. I'd like to control several things:

*   **Box/Cover Selection:** I need the option to generate just the box, just the cover, or both.
*   **External Wall Thickness:** I need to specify the thickness of the external walls.
*   **Internal Dimensions:** I need to set the internal length, width, and height.

Then, for the closing mechanism, I'd like to have two options:

*   **Screw Closing:**
    *   Specify the screw hole width and length, screw length and screw width
    *   Optionally include a countersink for the screw head, with the countersink height and width configurable.
*   **Mechanical Closing:**
    *   Specify the width and length of the mechanical tabs that will hold the cover to the box.

And then also:

*  **Ventilation:**
    *  Include an option to add ventilation holes.
    *  Specify the hole diameter, number of holes, and spacing between them.

Finally:
*   I need a way to control the internal wall thickness and height of the internal walls of the box, for any internal partitions I might want to add later. I need to be able to set this independently of external walls.
*   It would be great to have a small variable to offset the pieces so that it can be printed in place.
*   And please also include a small variable to avoid artefacts during printing.
*   I would also like the box to be rounded.

I don't need any special libraries, just the standard OpenSCAD features.

I want the code to be well-organized, easy to customize, and generate good quality output for 3D printing.

Could you help me with this?

I'd like to create a parametric corner bracket in OpenSCAD, something similar to the design I've seen, but I need to have it more flexible. The bracket needs to be robust, easy to 3D print, and include features to prevent rotation when it's mounted. I'm thinking of something that would work with t-slot aluminum extrusion, but I want the bracket to be easily adjustable to fit a variety of different dimensions.

Here's what I'm imagining:

**General Structure:**

*   The basic design should consist of two perpendicular walls, forming the corner.
*   There should be a gusset to reinforce the corner joint.
*   I'd like to have a "lip" or flange along the top edge of the bracket for added stiffness.
*   There should be some type of index protrusions or registration features built into the design to prevent rotation of the bracket once mounted. These should ideally protrude from the surfaces that will be in contact with the mounting surface.
*   The whole thing needs to be parametric so I can easily change things like size, thickness, hole diameters, and position of the index features.

**Specific Parameters I need:**

*   `Length`: The overall length of the bracket's sides (should be equal).
*   `Thickness`: The thickness of the material used for the bracket walls.
*   `Height`: The height of the bracket (how much it extends outward from the corner)
*   `holeDiameter`: The diameter for mounting holes.
*   `lipHeight`: Height of the lip feature above the main body of the bracket.
*   `lipThickness`: Thickness of the lip itself
*  `gussetThickness`: The thickness of the gusset
*   `indexProtrusionLength`: How far the index protrusions stick out
*   `indexProtrusionWidth`: Width of the index protrusions
*   `indexProtrusionOffset`: How far in from the corner the index protrusions should be located
* `mountingSlotOffset`: The offset for the two slot holes relative to center
* `mountingSlotWidth`: Width of the two slot holes in the mounting slot feature

**Specific Features:**

*   I'd like to have a mounting slot as opposed to circular holes that allows for a degree of adjustment when mounting the bracket. This should be centered on the corner of the bracket.
*   There should be a number of mounting holes along each edge, as well as along the central section of the gusset.
*   The index protrusions should be incorporated in such a way that they align with the mounting holes where appropriate.
*   The lip feature should wrap around the top edge of the two main walls.
*   The gusset should be a triangular brace along the inner corner to provide additional strength and should extend from near the base of the two walls up to some height just below the lip.

**OpenSCAD Library Usage:**

*   I'm planning to use the `BOSL2` library to construct the design, as it has a lot of built in primitives, functions and modules for more complex shapes.

Could you please generate the OpenSCAD file or files for me? Thanks.

Hi! I'm looking to design a modular box insert system, and I need a parametric OpenSCAD design to do it. I've been playing around with a few different versions I found online, but I really need something more flexible and customizable.

The core idea is a set of rectangular box inserts that can fit into a larger container (which I'm not designing right now). I want the inserts to have the following features:

*   **Modular Grid:** The inserts should be based on a grid system. I need to be able to specify how many modules wide and deep the overall insert is. Each module should be about 39.5mm by 39.5mm, and modules should be spaced 13mm apart within the container. This includes the area the peg fits into. So a 2x1 insert, the outside of the pegs would be ~92mm wide x 39.5mm deep, a 2x2 insert would be 92mm x 92mm.
*   **Height Options:** I need to be able to choose between a full-height insert (about 60.7mm tall) or a half-height insert (about 28.7mm tall).
*   **Internal Divisions:** I want to be able to divide the insert into smaller compartments using internal walls. I need to specify how many compartments wide and deep I want.
*   **Wall Thickness:** The walls should have a configurable thickness, which will probably be around 1.7mm.
*   **Peg System:** The inserts should have pegs on the bottom that slot into the base of the container. The pegs will be at each corner, with a diameter of around 7.4mm. I need these pegs to be positioned properly based on the grid of modules.
*   **Rounded Corners:** The corners should be rounded, both at the base and top, using a hull(). The bottom corners should be a little smaller than the top corners. The top corners of the main box should be larger than the interior corners.

The dimensions for the base and the top corners are a bit more detailed. The base corners should have a diameter of about 5mm. The top corner cylinders should use a diameter of 10mm for the outer corners, and an inner diameter of about 48.5mm, with slightly different values used to create the hull. The main dimensions to get the correct internal size of the box are important.

Here's an overview of the critical dimensions based on my existing, but not ideal, code:

*   `pegDistance = 39.5;`
*   `baseCornerDiameter = 5;`
*   `topCornerDiameter = 10;`
*   `topWidth = 52.5;`
*   `topLowerWidth = 51.5;`
*   `topInnerDiameter = 48.5;`
*   `bottomWidth = 49.5;`
*   `height = (h == "fullSize")? 60.7:28.7;`

I also need the code to be parametric, so I can easily change:

*   `modulesH`: Number of modules wide
*   `modulesV`: Number of modules deep
*   `numberOfHorizontalDivisions`: How many compartments wide
*   `numberOfVerticalDivisions`: How many compartments deep
*   `wallThickness`: Thickness of the walls
*   `pegDiameter`: Diameter of the pegs
*   `h`: height selection, "fullSize" or "halfSize".

I'd like to be able to render either just the box, just the pegs, or both together, controlled by a variable.

I think that's everything. Let me know if you have any questions!
