Okay, I'd like to design a flexible tube with bellows, similar to the design I found on Thingiverse but with some more flexibility in the parameters. I'm looking for a parametric OpenSCAD file that I can use to generate different sizes and shapes.

Here's a breakdown of the features I need, based on that original design:

*   **Bellows:** The tube should have a series of bellows, or folding sections, which give it its flexibility. I need to be able to control how many bellows there are.
*   **Tube Diameter:** I need to be able to set the outer diameter of the tube.
*   **Bellows Profile:**
    *   **Width:** The bellows should have a specific width.
    *   **Edge Radius:** The bellows edges should have a radius (fillet)
    *   **Slope:** I need to be able to control the slope angle of the bellows walls.
*   **Faceting/Resolution:**
    *   **Tube Resolution:** I need to be able to control the resolution of the circular tube, to avoid overly faceted geometry.
    *   **Bellows Edge Resolution:** I would like control over the layer height (faceting) of the curved parts of the bellows.
*   **Center Hollow:** I want the tube to be hollow throughout its length.

Essentially, I would like parameters for:

*   `Bellows_No`: The number of bellows sections.
*   `Tube_Diameter`: The outer diameter of the tube.
*   `Profile_Width`: The width of the bellows section.
*   `Profile_Edge_Radius`: The radius of the bellows edge fillets.
*   `Slope_Degrees`: The slope angle in degrees of the bellows walls.
*   `Tube_Circle_Resolution`: Control the fineness of the circle's tessellation.
*   `Edges_Layer_Height`: How finely to define the bellows' curved edge.

I'd like to ensure the bellows are evenly spaced along the tube. Also, it'd be good if the code were well-commented and easy to understand.

I’m not sure if it's needed for this design, but I'm also familiar with using the `BOSL` library if that helps.  Specifically, I've used `BOSL/transforms.scad`, `BOSL/shapes.scad`, and `BOSL/metric.scad`.

Could you generate this parametric OpenSCAD file for me?

Okay, I'd like to create a customizable 3D surface plotter in OpenSCAD, similar to the one I found online, but with some key changes to make it more flexible for my needs. I'm looking for a parametric design that can generate a variety of surfaces.

Here's what I'd like the design to be able to do:

**Core Functionality:**

*   **3D Plotting:**  The main function should generate a 3D surface plot from a mathematical function `z = f(x, y)`.
*   **Function Input:** Instead of hardcoding the function in `3dplot`, I need a way to easily specify the mathematical function  `f(x, y)` as a parameter.  This should allow me to define whatever surface I want within the OpenSCAD code. I don't want the function just to be a string; I need to be able to define a proper OpenSCAD `function` with a name I choose.
*   **Adjustable Plot Domain:** The plot should have adjustable x and y ranges using `x_min`, `x_max`, `y_min`, and `y_max` parameters.
*   **Grid Density:**  I'd need to control the grid resolution with parameters such as `grid_x` and `grid_y`, similar to the provided code.
*   **Bounding Box:** I want to set the minimum z-value as `z_min` to act as the bottom of the plot.
*   **Physical Dimensions:** I want to specify `x_size`, `y_size`, and `z_size` in mm as parameters, which will scale the surface. I'd like to specify this as a scaling and not just as an overall multiplier on the object. The scaling should be such that the generated shape is within the specified dimensions (e.g. `x_size` = 100mm means the model will take up a maximum of 100mm in the x direction).

**Additional Features:**

*   **Surface Thickness:**  It would be very useful if the surface could be given some thickness to create a solid object. I would like a parameter `thickness` to control how thick the object is.  It would be great if the thickness is perpendicular to the surface.
*   **Base Option:**  Optionally, I'd like a base that extends beneath the plot from `z_min`. I'd like to turn this on with a boolean `has_base` and set the base thickness using the `base_thickness` parameter, perpendicular to the `z_min` plane.
*   **Coloring:**  The model should be colorable with a parameter `color` that accepts a standard OpenSCAD color, or could be defaulted if no color is specified.
*   **Smooth Shading:** I'd like an option to provide smoother shading that isn't just flat faces. The code that I provided already uses triangles, but is there a way to provide smooth shading without excessively subdividing the polygons?
*   **Parameter Validation:** It would be helpful to add some parameter validation to the code to ensure the input parameters make sense to prevent issues and to allow the code to gracefully fail.

**Library Requirements:**

I don't need any special libraries for this, although if you have suggestions based on the features, feel free to use some of the standard libraries like `MCAD` or `BOSL`. I do not need any .scad files included, just a general description of libraries that are used.

**Output:**

I need a single OpenSCAD file, that includes all the functions and parameters. I'd like a function called `plotSurface()` or something similar, that takes all these parameters as arguments.

**In summary**, I'm looking for a powerful and flexible 3D surface plotter that I can easily customize and that is relatively straightforward to work with.  Could you provide a full .scad file for this?

Okay, I'm looking to create a parametric OpenSCAD design for an oloid, and I need a bit of flexibility. I've seen existing designs, and I like the idea of having different versions, especially a half oloid for easier printing and assembly.

Here's what I'd like the OpenSCAD file to do:

1.  **Oloid Core:** The design should include a core module for a standard oloid, created by hulling two perpendicular cylinders. This should be controlled by a radius parameter.

2.  **Full Oloid Option:** I want the option to render the full oloid using the core module, controlled by a type parameter.

3.  **Half Oloid Option:** I also need a module for a half oloid. This should be created by cutting the full oloid in half along its longest axis. This module should also be controlled by the type parameter.

4.  **Peg & Hole System:** The half oloid module should have an option to include pegs and corresponding holes for easier assembly when printing two halves.

    *   **Peg Size:** The pegs should be a fraction of the oloid radius (ideally, radius/8).
    *   **Peg Depth:** The depth of the pegs and holes should be configurable. I'd like to control peg depth using a `pegHeight` parameter.
    *   **Peg Gap:** There should also be a `pegGap` parameter to control the clearance between the pegs and holes. I want to make sure they fit together snugly after printing, but without being too tight.

5.  **Parametric Design:** All the relevant measurements should be controlled by parameters so I can adjust the size and fit, like:

    *   `_radius`: The radius of the cylinders that make up the oloid. This will roughly determine the final size.
    *   `_type`: An integer parameter to switch between full oloid (e.g., 1) and half oloid (e.g., 2).
    *   `_pegGap`: The gap between the pegs and the holes.
    *   `_pegHeight`: The depth of the pegs and holes.

6.  **Clear Comments:** The code should be well-commented to explain how the different parts work and what each parameter does.

I don't need any specific libraries (like MCAD or BOSL) for this simple design, so the base OpenSCAD language should be sufficient. I'd like the code to be relatively straightforward, so it's easy to understand and modify.

Could you create a parametric OpenSCAD file that fulfills these requirements?

Okay, I'm looking to create a parametric lampshade in OpenSCAD. I have an existing design I've been tinkering with, but I want to make it more easily adjustable.

The lampshade should be a rotationally extruded shape, primarily defined by a few key circles/points, which get hulled together.

Here's the basic structure:
1.  **Base:** The bottom should be a flat circular opening (represented by a square in the 2D profile). It will have a diameter of `FLOOR`, and a wall thickness, `WANDDICKE`.
2.  **Waist:** At a given height (`WEIGHT_CENTER`) there should be a bulge that's generated by another circle. This circle's radius is specified by `WEIGHT_RADIUS`.
3.  **Top:** The very top of the lampshade has a circular opening (again, represented by a square in the 2D profile). Its radius is given by `TOP_RADIUS`. The center of the top circle can be offset horizontally using `TOP_EXCENTER`, but for the time being, we can assume it's `0`.
4.  **Overall Height:** The lampshade should have a total height of `HEIGHT`.
5.  **Kabelöffnung:** There's a rectangular cable opening at the top, which should be sized according to parameter `KABELOEFFNUNG`.

The lampshade will have a thickness, defined by `WANDDICKE`.

I'd also like to add some decorative holes around the upper part of the lampshade. These holes should be created using `cylinder` primitives, rotated outwards a bit. They should be located near the top of the lampshade, at the height `HEIGHT-10`. Their number should be configurable via the `LOECHER_ANZAHL` parameter, currently 8. They should be rotated 20 degrees on the x-axis and be of radius 3 and height 20.

I would like the final design to be based on the difference of two solids, the first defined by the hull of the three defining points (base, waist, top) and the second defined by the same geometry of the first, but scaled inwards to represent the wall thickness. The cable opening will also be cut from the solid.

I need all these parameters to be easily adjusted to quickly change the lampshade's dimensions. Please generate a parametric OpenSCAD file based on the described design. I don't need any special libraries for this.

Okay, I'm looking to create a little tool to help with cutting cable ties. I've got an initial design in mind, but I'd like to make it more flexible using parameters and ensure it works as intended.

The basic idea is a cylindrical body with a slot through it, a bit like a clamp. The cable tie would be threaded through the slot before being used, and after it’s been tightened, you’d be able to cut it by slipping a blade into the slot.

Here are the key elements and parameters I have in mind:

*   **Cylinder Body:**
    *   `innerradius`: The radius of the hole through the cylinder. This needs to be adjustable for different size cable ties.
    *   `wallthickness`: The thickness of the cylinder wall.
    *   `height`: The height of the cylinder.

*   **Cable Tie Slot:**
    *   `cable_binder_width_plus_margin`: The width of the slot, allowing some space for the cable tie.
    *   `cable_binder_height_plus_margin`: The height of the slot.
    *   `cable_binder_position_in_percent`:  The vertical position of the slot as a percentage of the total cylinder radius. This is to allow different placements.

*   **Top Opening (for Inserting the blade):**
    *   `open_top`: A toggle ("yes" or "no") to enable or disable the top opening.
    *  `opening_angle`: The angle of the opening if it exists.

My current implementation uses the `slice` module adapted from code I found online (from http://rocklinux.net/pipermail/openscad/2012-August/003170.html) - that code should be included in the file.

I'd like a parametric OpenSCAD file that allows me to tweak all of these parameters easily. The current code uses `difference` and `cylinder` and `cube` and `linear_extrude`, which is great. I also need the `slice` function in the code.

I'm not using any specific libraries, but please use a well-formatted and commented code.

Can you help me with this?

			cube(size = [radius*2, cable_binder_height_plus_margin, cable_binder_width_plus_margin], center = true);

if (open_top == "yes"){
	rotate(90 + opening_angle/2)
	linear_extrude(height = height+2, center = true)
		slice(radius*2, opening_angle);
}

Okay, so I'm trying to design a little attachment for my faucet that turns it into a drinking fountain. I've got this starting point in OpenSCAD, but it's pretty rough and I think it could be way better.

Here's the basic idea, and the existing code:

The goal is to create something that fits onto a standard faucet and directs the water upwards, so you can drink directly from the stream. I want it to be printable, so it shouldn't have any crazy overhangs. I'm envisioning two main parts: a base that attaches to the faucet, and a ramp/tube that directs the water.

Here's the code I have so far, but it could use a serious upgrade!

```openscad
 /* ----------------------------------------------------------------------------
	Public Variables
---------------------------------------------------------------------------- */
//Less is more powerful:
Fountain_Diameter = 10; // [5:60]

//Your tap diameter:
Tube_Diameter = 30; // [5:60]

// Want elegance?
Fountain_Size = 40;	 // [30:100]

//It's a pure design opinion:
Tube_Size = 30; // [20:70]

//More, it'll be easier to print:
Wall = 4;//	// [1:10]

/* ----------------------------------------------------------------------------
	Piece Creation
---------------------------------------------------------------------------- */
difference() {
union() { cylinder(Tube_Size,(Tube_Diameter/2)+Wall,(Tube_Diameter/2)+Wall); rotate([45,0,0]) cylinder(Fountain_Size,(Fountain_Diameter/2)+Wall,(Fountain_Diameter/2)+Wall);}
union() {  translate([0,0,-WheightTube/2])cylinder(Tube_Size*2,Tube_Diameter/2,Tube_Diameter/2); rotate([45,0,0]) cylinder(Fountain_Size+(Tube_Size/2),Fountain_Diameter/2,Fountain_Diameter/2);}
translate([-Tube_Size,-Tube_Size,-(Tube_Size*2)]) cube([Tube_Size*2,Tube_Size*2,Tube_Size*2]);
}
```

**Key features I'm looking for:**

*   **Parametric Design:** It needs to be fully parametric. I want to be able to adjust things like the diameter of the faucet attachment (`Tube_Diameter`), the diameter of the water stream at the top (`Fountain_Diameter`), the length of the faucet tube (`Tube_Size`), the length of the fountain ramp (`Fountain_Size`), and the wall thickness (`Wall`). I've got some of those as parameters already, but it could be done better.
*   **Smooth Transition:** The transition between the faucet tube and the ramp should be smooth, not just a sharp angle. Think a nice curve, maybe part of a torus or a spline.
*   **Secure Faucet Fit:** I need a way to make sure it stays attached to the faucet.  Maybe a threaded section, or some sort of friction fit design - I'm open to suggestions. I'm assuming standard threads are going to be a pain to print cleanly, so maybe a simpler friction fit would be preferable.
*   **Printability:**  It needs to be easy to print without supports, or with minimal support. This is why the existing code is problematic with the sharp angle and all those cylindrical sections colliding.
*   **Robust:** I would also like the water stream ramp to not easily break, so maybe some kind of solid design, rather than just a thin tube.

**Additional Considerations:**

*   I'd like to avoid just directly using the code as it is. It’s a start, but its overly complicated and it doesn’t work the way I want. If it's helpful to reference, that's fine, but I'm thinking there's probably a simpler way to do it.
*   I don't have any specific OpenSCAD libraries I need to use right now, but if there are any particularly useful ones you'd suggest to accomplish some of this more easily, feel free! I'm open to trying them out.

Let me know what you come up with! I'm excited to see what you can do to improve this design.

Okay, I'm trying to design a custom gauntlet for a costume, and I'd like to do it in OpenSCAD so I can adjust it easily. I've seen some examples, and I want something similar to the gauntlet in the example I'm providing.

Here's what I need it to do:

**Core Functionality:**

*   **Parametric Design:** The design needs to be fully parametric, meaning I can easily adjust all key dimensions using variables. I want to be able to customize things like finger thickness, finger length, hand width, palm length, overall thickness, etc.
*   **Finger Segments:** The gauntlet should have multiple articulated finger segments, like the example. Ideally, this would be 3 or 4 segments per finger, plus a fingertip.
*   **Wrist/Palm Segment:** It also needs a wrist/palm section connecting the fingers. This segment should also be parametrically adjustable in length and width, and it should connect to the finger segments using a solid and robust join.
*   **Finger Curl Animation/Adjustment:** I'd like a variable that lets me adjust the angle at which the fingers are curled, or "make a fist". This isn't just for rendering in OpenSCAD; I'd like to be able to print it in different fist positions.

**Specific Parameters I want control over:**

*   `FingerThick`: Thickness of a finger (like a diameter), I plan to need values between 15 and 30mm
*   `FingerHeight`: Length of a finger from tip to knuckle, I'll need to be able to go from 50 to 140mm
*   `FingerWidth`: Width of the hand at the knuckles, I'll need this from 50 to 100mm
*   `PalmLength`: Length of the back of the hand, from knuckles to wrist, I want 50 to 140mm range
*   `HandThick`: Thickness of the hand below the pinky finger, I want a range of 15 to 45mm
*   `WT`: Wall thickness of the armor, likely 1 to 5mm
*   `Hand`: Select Right or Left hand
*   `RivetSize`: Size of decorative rivet-looking connections, range 1 to 8mm
*   `FCA`: Finger Curl Angle, from 0 (open) to 40 (tightly curled), maybe more later.
*  `CR`: Circle Resolution, or fineness of curved edges

**Key Design Features and Logic:**

*   **"Assembled" vs "Print" Layout:** I want a variable that lets me choose between two layout modes, one where the pieces are arranged as they would be when worn and another where they are laid out flat for printing. It seems like I need to lay them out with some offset to account for wall thickness
*   **Rounded Corners:** I want all the segments to have rounded corners and edges.
*   **Solid Connections:**  I need reliable connections between the finger segments. Snap locks and rivet-like connections seem good. I'd like a solid guard section that is also solid in the final version.
*  **Thumb Cutout:** The design needs to be such that it can allow for the thumb, which is why I need the Right/Left selector. I'm not worried about an articulated thumb in this design.

**Libraries:**

*   I'd like this to be done in "vanilla" OpenSCAD if possible, but if necessary I think I'd prefer to use the BOSL2 library for any advanced functions. It doesn't look like any other libraries are needed. I will not be using the MCAD library.

Can you provide me with an OpenSCAD file that meets these requirements? I'd like to be able to fully adjust and print this gauntlet.

Okay, I'm looking to create a finger grip for screws, specifically designed for use with standard hex head screws, like those used in tripod mounts (1/4"-20 UNC) but also with potential for different sizes. I've got an existing OpenSCAD file that gets pretty close, but I'd like to make it a bit more flexible and robust.

Here's a breakdown of what I need, taking inspiration from the original file:

**Core Functionality:**

*   **Screw Head Accommodation:** The design should create a finger grip that fits snugly around a hex head screw.  It should be able to accommodate different screw head sizes.
*   **Grip:** The grip needs to be comfortable for hand tightening and include finger indentations, or "dents" for better grip. The original had these as somewhat of a fluted design, and I'd like to have control over that as a parameter.
*   **Screw Thread Clearance:**  It should have a hole in the base for the screw threads to pass through, with a small amount of clearance.

**Specific Parameters and Customization:**

I need to be able to adjust these things through parameters:

*   **`dscrew`**: The outer diameter of the screw threads. I need to be able to adjust this to fit different threads, maybe even metric.
*   **`sscrewhead`**: The width across the flats of the hex screw head. Important to get the fit right.
*   **`hscrewhead`**: The height of the screw head.  This is used for the thinnest design, if the grip goes all the way to the bottom.
*   **`hgrip`**: The overall height of the main grip portion (excluding the protrusion).
*   **`dgrip`**: The outer diameter of the grip.
*   **`bevel`**: The amount of edge bevel on the grip.
*   **`hprotrus`**: The height of any protrusion or "lip" at the base of the grip, designed to provide extra purchase.
*   **`shift`**: This parameter is interesting. It currently controls how far the finger "dents" shift outward. I think it'd be good to retain this, but ideally also have the option to control the _depth_ of the dent, not just the shift. And perhaps the number of indentations around the circumference.
*   **`eps`**:  A small epsilon value for minor adjustments/tolerances. Perhaps an option for clearance generally as well.
*   **`$fa` and `$fs`**: Standard OpenSCAD values for circle and curve quality, so these should be exposed.

**Additional Features and Considerations:**

*   **Parametric Design:** I really want all of this to be adjustable via parameters, so I can easily modify it for different screws, and grip sizes.
*   **Library Dependencies:** I don't expect you to be working with other libraries, but If this could be made using one of the OpenSCAD libraries like MCAD, BOSL, BOSL2, dotSCAD, NopSCADlib, or BOLTS, that would be a very useful result for my own use.
*   **Clearance:** I need a bit of clearance around the screw head so that the grip doesn't bind, so those parameters in the existing code should be exposed to allow for adjustment.

Basically, I want a more robust and customizable version of this finger grip, with parameters for most if not all aspects. Please let me know if you need more information, but I think I've provided most of the details here.

Okay, so I'm trying to design a mouthpiece for my trumpet, and I found this really cool OpenSCAD file online that gets pretty close, but it's a little clunky and I think it could be better. I want to be able to customize it for different instruments too.

The current code uses a bunch of parameters to control the shape. I'll paste it below but here are the main things I want to be able to change:

*   **Cup Diameter:** This affects the tone and how easy it is to play high or low notes, a bigger diameter makes low notes easier and a smaller diameter makes high notes easier.
*   **Cup Depth:** This also affects tone, deeper cups for low notes and shallower cups for high notes.
*   **Cup Shape (Spherical/Conical):** A value between 0 and 1 to control how spherical or conical the cup is.
*   **Rim Width:** Wider rims help with stamina but reduce flexibility.
*   **Rim Shape (Flat/Round):** This is a parameter controlling the shape of the rim, a value between 0 and 1. Sharper rims for control and rounder rims for stamina.
*   **Throat Radius:** This affects the harshness of the tone, a sharper radius for a harsher sound.
*   **Throat Diameter:** A bigger throat gives more volume, but reduces control.
*   **Back Pipe Diameter:** The part that fits into the instrument.
*   **Bore Diameter:** The inner diameter of the bore.
*   **Mouthpiece Length:** Total length of the mouthpiece
*   **Printing Foot Height:** A small base for printing, but I also want to be able to turn it off.

Here's the code I'm starting with:

```openscad
// (c) 2012 Wouter Robers

// [Trumpet:16, Trombone:21] Larger Cup Diameters are optimized for lower ranges, giving a richer tone. Smaller diameters assist high range playing.

}
}
```

I would really like to:

1.  Make the code more readable and modular if possible.
2.  Potentially use libraries like BOSL or similar if they can make things easier for calculating curves and such.
3.  Have some preset values for different instruments, like trumpet and trombone, that I can easily switch between.
4.  Make the code easier to extend for further customization (like adding a custom "backbore" section).
5.   Make sure the code is still compatible with the Makerbot Customizer.

Can you help me write a better version of this? I'm excited to see what you can come up with!

Okay, so I'm trying to design a lamp shade adapter ring, and I've got a basic version working but it's not very flexible. I need something I can easily adjust for different lamp shades.

Here's the gist: The adapter ring is basically a cylinder with a smaller cylinder inside of it, and then a couple of cylinders that cut out sections from it. I made one in OpenSCAD, but it's pretty hardcoded. Here's the current SCAD code. I'd really like a version where I can specify the important dimensions as parameters.

```openscad
difference() {

union() {

	cylinder(3,29,29);
	cylinder(9,21.7,21.7);

}

	#cylinder(20,15,15);
	translate([0,0,3])
	#cylinder(20,19,19);
}
```

So, what I'm imagining is this:

*   **Outer Diameter:** I need to be able to set the outer diameter of the ring. My current one is 58mm (29mm radius * 2), which should fit a fairly common lamp shade opening.
*   **Inner Diameter:**  I also need to set the inner diameter, which is 43.4mm(21.7mm radius * 2) in my current code, where the lamp will actually sit on.
*   **Height:** I need to be able to set the overall height of the ring, which is 12mm in my current version (3mm + 9mm). I will need some flexibility for this height, as some shades are very thick.
*   **Top Cutout Diameter:** I need to set the diameter of the top cutout, it's 30mm in this example, but I'd prefer it's parametric. Also, it would be nice to set the height of the cutout so that I don't remove too much material. My cutouts also start at z=3, which should be a parameter as well.
*   **Bottom Cutout Diameter:**  Same as the top cutout but for the bottom. In this example, it's 38mm. The height and starting z are the same as the top cutout (z=3).

Ideally, I'd like these to all be parameters at the top of the file. I'd really appreciate it if you could generate a parametric OpenSCAD file for me. I'm not using any libraries right now, but I'm open to them if it makes the design easier to generate.

Thanks!

Okay, I'm looking to design a set of round containers with lids using OpenSCAD, and I need a bit of flexibility in the design. I've already experimented with something similar and have a working example that I'm happy with, but I'd like to rebuild it with more flexible and parametric controls.

Here's what I need:

**Core Shape:** The containers will be cylindrical, with rounded corners (filleted edges) on both the base and the lid. I want to control the radius of these rounded corners.

**Container Type:** I need to be able to easily toggle between generating the *base* or the *lid* part of the container using a simple variable.

**Dimensions:**
*   **Outside Diameter:** The main outside diameter of the container should be adjustable. This includes the side walls.
*   **Base Height:** For the base, I need to be able to set the total height of the base (including the bottom, but *not* any lid elements).
*   **Wall Thickness:** The thickness of the walls, the bottom of the base, and the lid should all be the same and adjustable.
*   **Lid Gap:** There should be a small, adjustable gap between the lid and the base for a proper fit.
*   **Lip Height:** The lid has a lip that inserts into the base; I need to be able to control the height of this lip.

**Rendering:** I'd like to control the resolution of the curved surfaces. It would be great if that could be defined through a variable too.

**Specific Features:**
*   The base will have a flat bottom.
*   The lip on the lid should fit inside the base with the specified gap.
*   The lid should also have rounded edges that match the base.

Essentially, I want to recreate the attached design, but in a single parametric file instead of having some hardcoded values. Can you help me design an OpenSCAD file that can achieve this? I don't want to use any libraries except the standard ones that come with OpenSCAD. I'd prefer a solution without any external libraries if possible. The attached file is just an example of the general design I'm trying to achieve, not a set of requirements.

Okay, so I need an OpenSCAD design for making customizable Braille nameplates and keychains. I'd like it to be parametric, so I can easily change things like the text, size, and whether it's a keychain or just a nameplate.

Basically, I want to be able to input some text, and have it rendered in Braille, with raised dots. I'd like to control the size of the Braille characters themselves, and the overall size of the nameplate/keychain. I'd also like to be able to specify whether it should include a hole for a keyring.

Here's a breakdown of what I'm thinking:

*   **Text Input:** A variable for the text to be displayed in Braille.
*   **Size Control:** A variable for the overall height of the Braille characters. This should affect the size of the dots and the spacing.
*   **Keychain Option:** A boolean or string variable to toggle between a nameplate and a keychain. If it's a keychain, it needs a hole for the keyring, ideally near the left edge.
*   **Braille Encoding:** I'll need a method for converting the text into Braille. Each letter has a specific pattern of 6 dots, and I'll need to define these patterns. I don't know how to do that so will need the AI to figure that out.
*   **Build Platform Indicator:** Optionally (but helpful), have a way to show the printer build area as a semi-transparent cube, so I can ensure it fits my printer's bed. I'd want to be able to turn this on/off.
*   **Letter Spacing:** There should be a bit of horizontal space between each braille character, based on the font size (the one from the size control variable). This makes them easier to read/feel.
*   **Base Plate:** There should be a base plate behind the braille characters, to keep them rigid and make them more printable. The height of this base plate should be adjustable as well.
*  **Unit:** We should be working in mm.

I think that covers it! This is similar to something I saw online but I want a custom design from the ground up. I'm new to OpenSCAD, so the more detailed the code, the better. I am not using any special libraries so any modules must be created from scratch. Can you create the OpenSCAD files for me?

Okay, I'd like to design a tri-glide buckle for webbing, similar to the one I have a SCAD file for (broken-edge-tri-glide_v1.1.scad), but I need it to be more flexible and have some additional parameters.

Here's what I'm looking for:

**Core Functionality:**

*   It should be a tri-glide, with a central bar and two side openings for webbing to pass through.
*   The overall shape should be a rounded rectangle, with the option to control the roundness of the corners.
*   The tri-glide needs to have the ability to break or remove material on its outer edges, creating a chamfer or bevel on the top and bottom of the outer edges. I'm not looking to round the edges, but create a sharp chamfer or bevel on the top and bottom outer edges.
*   I need to be able to control the thickness of the overall tri-glide piece as well as the center bar and side edges independently.

**Parameters I Need:**

*   **`webbingOpeningWidth`:** The width of the opening for the webbing (the internal width of the central area) - in mm.
*   **`webbingGapWidth`:**  The space or gap between the webbing opening and the edge of the tri-glide (the internal gap) - in mm.
*   **`sideEdgeWidth`:** The width/thickness of the side edges of the tri-glide (the outer edges) - in mm.
*   **`mainEdgeWidth`:** The width/thickness of the main edges along the side opening (where the webbing bends around) - in mm.
*   **`centerWidth`:** The width of the central bar - in mm.
*   **`overallHeight`:** The overall thickness or height of the tri-glide piece - in mm.
*   **`cornerRoundingPercent`:**  A percentage value controlling how much the corners are rounded. It should act as a percentage of the max possible radius value based on the minimum of edgeWidth. It needs to be adjustable from 1 to 100.
*    **`cornerBreakage`:**  This parameter specifies how much material to remove from the outer edges to form the chamfer/bevel, in mm. This should remove material from the top and bottom, leaving the center thickness intact.

**OpenSCAD Specific Requirements:**

*   I'd like the design to be entirely parametric, allowing me to easily modify the dimensions using the parameters listed above.
*   The design needs to use a `minkowski()` operation with a rounded cylinder to form the rounded rectangle with the correct corner radius as a base. This will help make sure the corners work smoothly. The chamfer should be applied to the main body.
*   I'm looking to avoid using any external libraries if possible, I want this to be a clean, standalone SCAD file.

So, could you generate the OpenSCAD code for this? I'd really appreciate it.

Okay, I'm looking to create a customized version of a 3D-printable heart-shaped box with a locking mechanism, similar to the one described here. It seems like a complex design, but I'd like to be able to control its dimensions and add custom text.

Specifically, I want a parametric OpenSCAD design that allows me to:

1.  **Set the Words:**  I need to be able to specify two different text strings that will be printed on the top faces of the heart halves.
2.  **Font Choice:** The code should allow me to choose a font from a DXF file. The existing design uses "write/Letters.dxf", "write/orbitron.dxf", and "write/BlackRose.dxf" as examples, so I'd like to use the same approach.
3.  **Word Height:** I need a parameter to control the height of the letters in the words.
4.  **Midsection Length:** I want to specify the length of the straight, parallel section in the middle of the heart (parameter "L").
5.  **Flat Face Width:** I want to set the width of the flat faces of the heart (parameter "W").
6.  **Box Height:** I need to control the overall height of the box (parameter "H").
7.  **Hinge Spacing:** I want to control the distance between the hinges (parameter "x_hinge").
8.  **Wall Thickness:** I need a parameter to set the wall thickness of the box (parameter "T").
9.  **Nub Depth:** I want to set the depth of the sliding nubs used in the locking mechanism (parameter "nub").
10. **Tolerance:** I need a tolerance parameter for moving parts, to avoid binding and ensure a smooth opening (parameter "tol").
11. **Render Quality:** I'd like to be able to control the rendering quality, potentially with some speed-vs-quality parameter (parameter "quality", with 1 being Draft, 2 being Medium, and 4 being Fine, as mentioned).
12. **Animation (Optional):** If possible, it would be nice to have a built-in animation option that could show the box opening and closing.

The design makes use of the `build_plate.scad` and `write/Write.scad` library files, so please keep that in mind when creating the new code. I want to be able to specify different build plates (Replicator 2, Replicator, Thingomatic, or Manual) as well as the manual dimensions if the manual build plate is selected. The base code seems to have variables `build_plate_selector`, `build_plate_manual_x` and `build_plate_manual_y` to control this, so please include that functionality.

Basically, I'd like a fully parametric version of this heart box that I can easily customize with my own words and dimensions. I want to be able to print it fully assembled.

Okay, I'm looking for an OpenSCAD design for a bar clamp rod adapter. I want to be able to clamp a rod to a surface using a regular bar clamp, and this adapter will create a secure, non-damaging way to do it.

Here's what I envision:

The adapter should have a rectangular base with a groove in the middle to hold the rod. The base should be wide enough to fit the jaws of a standard bar clamp.  The groove should be deep enough to securely hold the rod, but not so deep that it weakens the adapter too much. There should also be a lip surrounding the clamping area, to raise it up a bit from the surrounding surface.

I need the design to be parametric, so I can adjust these dimensions:

*   **`jawLength`**: The length of the area where the bar clamp will grip.
*   **`jawWidth`**: The width of the area where the bar clamp will grip.
*   **`lipThickness`**: The thickness of the raised lip around the clamping area.
*   **`lipHeight`**: The height of the raised lip around the clamping area.
*   **`grooveDepth`**: The depth of the groove that holds the rod.
*   **`minimumThickness`**: The minimum thickness of the adapter material at the thinnest point (between the rod groove and the underside).

So, in short, I need an OpenSCAD file with these parameters that creates a solid, printable adapter that can clamp rods securely using a bar clamp without damaging the rod or the surface it's clamped to. I don't want any threads on the base that could mar the surface that it rests on.

Could you generate that for me? I do not have any particular libraries in mind, but if you need to use any specific ones, please let me know which ones, but I do not need you to include them in the response.

Okay, I'd like to design a parametric desk hook that I can 3D print. I need it to be adjustable so it can fit different desks and hold my headphones.

Here are the features I need:

1.  **Overall Shape:** The hook will have a flat, vertical section that clamps onto the desk, a horizontal section that extends under the desk, and a final vertical section that acts as the hook itself. Think of it like a 'C' shape that's been bent 90 degrees.
2.  **Parametric Width:** I need to be able to specify the overall width of the hook, which will mostly be the width of the vertical section that clamps to the desk. I'll call this `width`.
3.  **Parametric Desk Height:** I need a parameter for the thickness of the desk that the hook will be clamped to. This value will be the height of the middle, horizontal section of the hook. I'll call this `desk_height`.
4.  **Parametric Hook Height:** The height of the actual hook part that holds my headphones needs to be adjustable as well. Let's call this `hook_height`.
5.  **Parametric Thickness:** All of the parts of the hook should be a consistent thickness. Let's call this `thickness`.
6.  **Parametric Depth:** The horizontal extension of the hook should be adjustable for different desk overhangs. Let's call this `depth`.
7.  **Optional Headphone Cable Hole:** I would like to include an optional hole through the hook to feed my headphone cable through. This parameter will be the diameter of that hole and I'll call this `jack`. If the `jack` diameter is 0, no hole should be generated.
8.  **Filleted Edges:** I would like for the edges of the hook to be rounded using fillets to make it look smoother. I would like for these to be controllable as parameters, and I would like to be able to control both vertical and horizontal fillets. I would also like to be able to specify a single fillet radius for all corners, if needed.

I'd like this to be written in OpenSCAD and be entirely parametric, so I can tweak the design later without having to completely redesign it. I would like to be able to call the main module of the design using `desk_hook(width, desk_height, hook_height, thickness, depth, jack);`. I've looked into the source and I would like to use the helper module `fillet()` and `cube_negative_fillet()`, and `cube_fillet_inside()`, and `cube_fillet()` from the attached code. The module `fillet()` is a module that subtracts a cylinder from a cube to generate a fillet. The other modules modify a cube by applying fillets and subtracting them from the cube. Please do not include any specific libraries like MCAD or BOSL.

Okay, I'd like to design a loaded die, similar to the one I have attached, but I'd like it to be more parametric and easier to customize.

Here's what I'm looking for:

**Core Functionality:**

*   **Loaded Number Selection:** The user should be able to specify which face of the die is weighted (i.e. the number that is more likely to be rolled). This should be a parameter ranging from 1 to 6.
*   **Hollow Cavity:** Instead of a fixed cube, I'd like to be able to control the size and depth of the hollow spot below the loaded number. Specifically, I want to be able to define these parameters:
    *   `cavity_width`: The width and depth (since it will be a cube) of the cavity.
    *   `cavity_depth_ratio`: This should be a ratio relative to the radius of the sphere. For example, a ratio of 0 would mean no depth, while a ratio of 1 would go to the center of the die.
    *   `cavity_offset_ratio`: This should be a ratio that allows for offset of the cube within the sphere, as a ratio relative to the sphere's radius.

*   **Sphere Radius:** The radius of the sphere used to make the rounded die should be a customizable parameter.
*   **Dice Size:** The overall size of the dice, which is currently fixed at 20mm on each side, should be parameterized. I'd prefer to specify the *edge length* of the die.
*   **Dot Size:** The dots on each side of the dice should be parameterized by the dot sphere radius.
*   **Dot Depth:** The depth that the dots indent should be parameterized.
*   **Number Placement:** The dots on each face should be placed automatically based on the face value (1-6) and parameters.
*  **Number Rotations:** The loaded number should be rotated to the top face.

**Specific OpenSCAD Requirements:**

*   The design should use the `minkowski()` function for creating the rounded die shape, like the existing file.
*   It should use the `difference()` function to subtract the hollow cavity from the dice body.
*   It should use the `translate()` and `rotate()` functions to position the dot on the various faces, and correctly rotate the cavity.
*   The dots should be made from spheres and translated/rotated accordingly
*   It would be helpful if the dot creation modules could be made more modular.

**User Interface/Parameters:**

The OpenSCAD file should clearly define the following parameters at the top:

*   `loaded_number` (integer, 1-6): The face that will be more likely to be rolled.
*   `dice_edge_length` (float): The length of one edge of the die cube before the minkowski.
*   `sphere_radius` (float): The radius of the sphere used in the `minkowski()`.
*   `cavity_width` (float): The width/depth of the hollow cavity cube.
*   `cavity_depth_ratio` (float): The depth of the cavity as a ratio of the sphere's radius.
*   `cavity_offset_ratio` (float): The offset of the cavity as a ratio of the sphere's radius.
*   `dot_sphere_radius` (float): The radius of the spheres used to create the dots.
*   `dot_depth` (float): The depth that the dots indent.
*   `fn` (integer): The $fn value for spheres

**Output:**

The output should be a single 3D model of the loaded die, ready for STL export.

**Libraries:**

* I will not be including any code. Please do not assume I am attaching any OpenSCAD libraries, but if you use libraries in your response, please name them explicitly in the response.

Essentially, I want to take the existing concept and make it more customizable and parameter driven. I'm hoping this will make it easier to play around with the loading and the overall shape of the die.
