Hey there, I'm looking to create a custom Easter egg design using OpenSCAD, and I was hoping you could help me out! I've seen a design that uses a displacement map on a egg shape, and it's pretty much exactly what I want. It uses an image to push the surface of the egg out or in, creating a cool embossed effect.

I'd like the design to be parametric so I can easily change things. Here are the key things I want to be able to control:

*   **Egg Shape:** The overall egg shape is adjustable from spherical to elongated. I'd like to control the "egg-ness" using a shape parameter, similar to how it is described in the attached file where a value of 0 is a sphere, 7 is a hen's egg, and 100 is a long blimp-like shape.
*   **Egg Length:** I need to be able to specify the length of the egg in millimeters.
*   **Displacement Image:** I want to be able to import a grayscale image to use as a displacement map, where lighter pixels push the surface of the egg outward and darker pixels push the surface inward or not at all.
*   **Displacement Depth:** I need a parameter to control the magnitude of the displacement effect, also in millimeters. I’d like to be able to make this negative for indentations.
*   **Image Scaling and Tiling:** I want to be able to specify how the image is scaled around the egg's circumference and length. I also want the option to repeat the image multiple times around the egg if it's too small.
*   **Resolution:** A control for how many points make up the mesh; it should have an option for draft preview and final render. It should also use an oversampling parameter to adjust number of points/pixel to achieve anti aliasing.
*   **Base:** The option to have a simple cylindrical base added to the egg for easier 3D printing. It should also allow you to control the clearance between the egg and base.
*   **Hollowing:** The option to hollow the egg for less material and faster printing.

It would be great if the design could use trigons to avoid non-planar face issues that can sometimes occur with quads, but also have an option to use quads when there is no boolean modification.

I'd like a module that creates the embossed egg with all the adjustable parameters, and the option to create a full object, with the base, for printing.

Also, if you could echo the parameter values to the console for my convenience, that would be great! And I’d prefer you not use any third party libraries or code. I also have a feeling I may want to create more objects from the parametric model, so maybe make sure the module itself is easy to use.

Hey, I'm looking to generate some parametric wingnuts in OpenSCAD, and I need a bit of help getting started.

I'd like the wingnut to have a few adjustable parameters: the major diameter (the outer diameter of the nut's body), which will also determine the minor diameter (the diameter of the hole) as a function of the major diameter, the height of the nut, the overall size of the wings and their wall thickness, and a boolean flag to turn the wings on or off.

Specifically, the minor diameter should be 75% of the major diameter. The default nut height should be twice the major diameter. I'd like the wings to extend out to a distance of 1.3 times the major diameter, and have a wall thickness equal to half of the major diameter. The wings themselves are just cylinders with rounded ends, sort of teardrop-shaped.

I'd also like the option to set a small tolerance value; to be used in the difference operation to ensure we get the right internal diameter for threads. I have included a simple example .scad file for you to examine below. It does everything I need but lacks parametric settings for the wing shape, and the tolerances are not parametric.

```
//
//  parametric wing nut
//

major = 4.0; // [ 2.0, 2.5, 3.0, 4.0, 5.0, 6.0, 8.0, 10.0, 12.0 ]
minor = major*0.75; // 2.25 for M3, 3.0 for M4, 3.9 for M5, 4.6 for M6, 6.25 for

have_wings = true; // [ true, false ]

d = 1*0.01;

nutheight = 2*major;
wingmaxr = major*1.3;
wingwall = major*0.5;

module wing() {
	if (have_wings) hull () {
		translate([nutheight/2,0,major]) rotate([90,0,0])
			translate([0,0,-wingwall/2]) cylinder(r = nutheight/2, h = wingwall, $fn=30);
		translate([wingmaxr*2.0,0,wingmaxr*1.4]) rotate([90,0,0])
			translate([0,0,-wingwall/2]) cylinder(r = wingmaxr, h = wingwall, $fn=30);
	}
}

difference () {
	union () {
		cylinder(r = major, h = nutheight, $fn=6);
		wing();
		rotate([0, 0, 180]) wing();
	}
	translate([0, 0, -d]) cylinder(r = minor/2, h = nutheight+2*d, $fn=30);
}
```

I'm not using any special libraries for this, just basic OpenSCAD primitives. I'd really appreciate it if you could write the OpenSCAD code from scratch. Thanks!

Hey, I'm looking to create a customizable, Minecraft-style creeper model for 3D printing, and I want to be able to adjust some key features. I need the model to be designed in OpenSCAD.

Here's what I have in mind:

*   **Basic Shape:** The creeper should consist of a rectangular body, four rectangular legs, and a cube-shaped head. The whole model should be built from stacked and combined cubes. I don't want any rounded edges or fancy features. The body should be stacked above the legs and the head should be stacked on top of the body.
*   **Pixelated Style:** I want the individual cubes ("pixels") that make up the creeper to be configurable in size, which will affect the overall scale. The cube size should be a parameter.
*   **Head Rotation:**  The head should be able to rotate around its vertical axis, and this rotation angle should be adjustable.
*   **Body-Leg Overlap:** I need some extra overlap between the body and legs for mold-making purposes. I would like this overlap to be an adjustable parameter. The overlap is in the z-direction, such that the legs extend a configurable distance into the body.
*   **Mold Making Considerations:** The model will be used to create a mold. So I may need a slight offset for head rotations. I would need to make an adjustment to the head angle when `mold_making` is set to true.
*   **Single Extrusion:** The design should be a single solid object and can be printed on a single-extrusion 3D printer. I want the legs, body, and head to be connected (no separate parts).
*   **Modular Code:** The code should be organized into modules for legs, body, and head. It's easier to read and modify when each section is in its own module.
*   **Eyes and Mouth:** The head should include the creeper's distinctive mouth and eyes. Use simple cubes for these. The mouth should be made up of 3 parts - two 'vertical' cubes on the edges, and one horizontal cube. The eyes should be made of up 3 parts, two 'vertical' cubes and one 'horizontal' cube on top of those two.

I am not looking to use any existing libraries, other than the built-in OpenSCAD functionality. Could you generate the OpenSCAD code for me? I think I have all the parameters covered, but let me know if you have any questions.

Hey, I'm looking to generate some hyperbolic saddle shapes in OpenSCAD, and I need a little help. I want to be able to control the size, thickness, resolution, and the scaling along the x and y axes of the saddle. I also want to be able to create these saddles, mirror them across the x, y, and both x and y axes, and have all of that output as a single object. Essentially, I'm looking to make a symmetrical four-lobed shape that's based on a saddle.

I'm thinking of setting a `Resolution`, `Size`, and `Thickness` variable for all of the saddles. There will also be variables that control the scaling of the saddle along the x axis `Scaler1` and the scaling along the y axis `Scaler2`. The saddle function itself should take in all these variables. This function will use a nested for loop structure to iterate through all of the x and y points with the specified resolution. For each of these points I want to create a quadrilateral using the next set of x and y points as well. This quadrilateral is how the saddle will be constructed. This means that the `z` position of the saddle will need to be calculated based on the input x and y positions and scaled by the scale factors `Scaler1` and `Scaler2` to create a hyperbolic shape. Additionally, each quadrilateral should have a mirrored version shifted down by the thickness variable to give it volume. These two quadrilaterals should then be connected by their corresponding vertices. Finally, I want the saddle function to be called four times, once without any mirroring, once mirrored along the x axis, once along the y axis, and once along both.

Could you write an OpenSCAD file that does all of this?

Hey there, I'm looking for a customizable design for a multi-drawer storage box, something I can 3D print. I've been playing around with some designs but I'm hoping you can help me create something a bit more polished. I'd like the design to be fully parametric, so I can adjust things like the number of drawers, their dimensions, and the overall box size easily.

Here’s what I'm envisioning:

**General Box Features:**

*   **Modular Drawers:** The box should house multiple drawers, and I'd like to be able to specify the number of drawers.
*   **Parametric Dimensions:** Everything needs to be adjustable: overall box width, depth, and height, along with the individual drawer widths, depths, and heights.
*   **Wall and Floor Thickness:** I want to control the thickness of the box walls and drawer floors independently.
*   **Clearance:** It should be possible to set a clearance value between the drawers and the box frame to ensure smooth movement.
*   **Rounded Corners/Fillets:** I’d prefer to have the option to include rounded fillets on the corners of the drawers and the main box.
*    **Slotted Sides:** I'd like to have the box's sides have a pattern of slotted holes. I'm looking to specify their size, and spacing.
*   **Mouse Ears:** The box will also need the small discs (mouse ears) on the corners of the box to help with print adhesion. I'd like to control their radius and height.

**Drawer-Specific Features:**

*   **Variable Sections:** I'd like to make drawers with one, two, three, or four sections within each drawer. I'd like to be able to specify the sections when choosing the part to print.
*   **Handle:** A simple, integrated handle should be included, which can be adjustable in size. I'd like the option to make this as a cutout or a protruding handle.
*   **Text Labels:** I want to add a text label to each drawer. This needs to be customizable: text content, font, text height, spacing, and shifting. I’d like to select whether it's embossed or not.
*   **Bumpers:** There should be small spheres on the sides of the drawers to help with smooth motion.

**Libraries:**

I'd like the code to use the `roundedBox` function from the `boxes.scad` library (or equivalent if you need another library to handle rounded boxes). I'm assuming we can make that library separate from the rest of the code.

I think that's all. Let me know if you need any more information. I'm really looking forward to seeing what you come up with! Thanks!

Hey, I'm looking to create a customizable 3D printable plaque-type thing, and I'd like your help with the OpenSCAD code.

Essentially, it'll be a base with some geometric cutouts and then have raised text on top. I want to be able to specify the text, font, font size, font thickness, and base thickness. The text should be centered on the base. I'd like to use the `write` library for the text generation part, specifically the functionality of the `writecube` module. I'm intending to use the `orbitron.dxf` font provided within the `write` library, but I'd like to make that font customizable by including a parameter.

For the base, I envision a square with some overlapping triangle cutouts. Specifically, there should be:
1.  A triangle cut out from the top left corner, with the tip pointing up and towards the center of the square.
2.  A triangle cut out from the top right corner, with the tip pointing up and towards the center of the square.
3.  A triangle cut out from the bottom left corner, with the tip pointing down and towards the center of the square.
4. A triangle cut out from the bottom right corner, with the tip pointing down and towards the center of the square.

The cutouts should be achieved using difference operations on the square, and will be mirrored diagonally across the square from each other.

I'd like to have the following parameters:
*   `message`: The text string to be printed
*   `font`: The font .dxf file to use from the `write` library (default should be `orbitron.dxf`).
*   `font_size`: The height of the text.
*   `font_thickness`: The thickness of the text.
*   `base_thickness`: The thickness of the base.
*   `base_size`: The width and height (as the square base)

Could you generate the OpenSCAD file(s) for this? I’d like to have all code, including code relating to the write library, bundled together into a single file. It's important to me that it's easy to use and customize using the parameters I defined, so it'd be great to have comments describing the function of each of those parameters and parts of the code.

//Font Size
font_size = 10;
//Font Thickness
font_thickness = 5;
//Base Thickness
base_thickness = 10;

linear_extrude(height=base_thickness,center=true){

Okay, I'm looking to create a customizable card box, and I'd like to use OpenSCAD to design it. I've got a rough idea of the features I need. I'd like the design to be parametric, so I can easily adjust dimensions and features for different uses, kind of like the file I've provided, but I'd like you to start from scratch.

Here are the core parameters I'd like to control:

*   **Overall Box Dimensions:**
    *   `box_length`: The length of the box.
    *   `box_width`: The width of the box.
    *   `box_height`: The height of the box.
*   **Wall Thickness:**
    *   `box_thickness`: The thickness of the box walls. I typically prefer 3mm.
*   **Corner Rounding:**
    *   `box_rounded_corner`: The radius of the rounded corners.
*   **Divider Slots:**
    *  `number_of_slots`: The number of sections created by the dividers (not the number of dividers).
    *   `tolerance`: Extra space on each side of the divider slots for ease of fitting.
    *  `div_height_tolerance`: Amount to shorten the divider height.
*  **Divider Dimensions:**
    * `div_thickness`: The thickness of the dividers.
*   **Stacking Rim:**
    *   `stacking`: A boolean to enable or disable a stacking rim.
    *   `rim_tolerance`: Extra space for the stacking rim.
*   **Cut Ends:**
    *   `cut_ends`: A boolean to cut circles on the ends of the box.
	*	`div_cut_ends`: Controls if and where circles are cut on the ends of the dividers (top, bottom, or both).
*  **Rim Heights:**
	* `upper_rim_height`: The height of the upper rim.
	* `lower_rim_height`: The height of the lower rim. The lower rim should be 0.4mm deeper than the upper.
 *  **Stack Rim Thickness:**
 	* `stack_rim_thickness`: The thickness of the stack rim itself.

I'd like the code to be modularized with separate modules for building the box, the dividers, the stacking rims, and the rounded rectangle, similar to my example code. I would like two separate parts to be created - the box and the divider. There should be a global variable `part` that can be set to "box" or "divider" so that a single print module only prints out one part at a time.

The stacking feature is just to prevent boxes from sliding off each other, not for a secure snap fit.

Could you generate the OpenSCAD file(s) for this, and ensure they use the `hull()` and `linear_extrude()` functions for the rounded rectangle? No external libraries are necessary.

[Assistant]
card_caddy_v3_rc2_customizer.scad:
```
// Which one would you like to see?
part = "first"; // [first:Box Only,second:Divider Only]

box_length = 96; //box length
box_width = 73; //box width
box_height = 47; //box height

//wall thickness in mm
box_thickness = 3; //box wall thickness

//corner rounded radius in mm
box_rounded_corner = 1; //rounded corner radius

//extra space on each side for divider slots
tolerance = 0.2; //extra space on divider slots

//extra space on the stacking rim (bottom)
rim_tolerance = 0.4; //extra space on the rim

Hi, I'm looking to create a parametric OpenSCAD design for embossed Easter eggs, but I want more control and flexibility than the existing script I've been using. I'd like to be able to specify the egg shape, image embossing, and base all as parameters.

Here's what I need:

*   **Egg Shape:**
    *   I want to be able to control the overall egg shape, from spherical to elongated, using a single "shape" parameter (similar to the existing `egg_shape`).
    *   The egg should be able to have different lengths and sizes.
    *   I want to control the egg length independently.
    *   I want the egg to be centered on z=0.

*   **Image Embossing:**
    *   The embossing should use an image map (like the existing one) with pixel values that control the embossing depth.
    *   I need parameters for image width and height, to define the resolution of the pattern.
    *   I should be able to repeat the image seamlessly, or not repeat it and just put it inside a specified range of latitudes and longitudes.
    *   I should be able to specify how many image cycles per image "flip". This should allow for seamless repetition.
    *    I need the ability to define the embossing depth using a depth parameter that can be negative.
    *   The pattern should be applied smoothly to the curved surface.
    *   I need to specify image boundaries using start/end longitude and latitude angles in degrees (like the `ud0`, `ud1`, `vd0`, `vd1` parameters in the existing code).
    *   The image map should be a simple list of integers.

*   **Base:**
    *   I need an optional base for 3D printing, with a clearance setting to make separating the egg easy.
    *   The base should have a hollowed-out section for saving on printing material, and a bottom hole to remove the hollow section from the print job.
    *   The base should be centered at z=0.
    *   I need to be able to control base size and shape using parameters for base diameter and base height.

*   **Mesh Resolution:**
    *   I need to be able to control the mesh density without having to calculate the number of divisions manually.
    *   I'd like to specify an "overSampling" parameter that controls how many grid vertices to create per image pixel.
    *   The resolution should automatically adjust based on image size and angles.
    *   Anti-aliasing should be applied when the oversampling is greater than 1.
    *   I want to choose between only triangles or triangles and quads depending on the whether I'm using a base, or another boolean parameter.

*   **Parameters and Modules:**
    *   All of these should be controlled by parameters (like in the existing code)
    *   I need a module for the egg itself and a module for the simple base.
    *   I should be able to toggle a "moduleMode" parameter to disable the display of a default egg shape and allow module-only use.

*   **Output:**
    *   The final output should be an egg with the image embossed on it, with an optional base.
    *   The program should use trigons or quads for faces to avoid non-planar surfaces.
    *   The parameters should be echo'd to the console.

I know this is a lot, but I really need a flexible and customizable Easter Egg generator for 3D printing. I don't mind if you break it down into multiple .scad files. I don't need any existing OpenSCAD libraries to be used. Let me know if you have questions. Thanks!

Hey, I'm looking to get a custom shelf hook designed. I've been playing around with some existing designs, but I want something fully parametric and robust. Basically, I want a hook that slides over the edge of a shelf, kind of like a modified wall hook, but specifically for shelf edges.

Here are the core parameters I'd like to control:

*   **`thickness`**: The thickness of the material of the hook itself. This dictates the visible line thickness when viewed from above or the front.
*   **`width`**: How far the hook sticks out horizontally from the shelf edge along the wall.
*   **`length`**: The length of the part of the hook that rests on top of the shelf and under the shelf.
*   **`shelf`**: The thickness of the shelf the hook will mount to.
*   **`hang`**: How far the hook hangs down below the bottom of the shelf.
*   **`gap`**: The diameter of the bends in the hook -- specifically, the tight curvature, before it flares out.
*   **`tip`**: The height of the small vertical part on the end of the hook that stops things from slipping off.
*   **`trough`**: The width of the trough of the hook - this affects the shape of the hook.  A large trough will be a wide "U" shape, and a small trough will lead to more of a semicircle.

The hook will have a flat section that sits on top of the shelf and a similar flat section that sits below the shelf. These two sections are connected by a vertical part that goes down the side of the shelf. Then, there's a curved hook section that's made up of two rounded parts that have a gap between them. At the end of the hook, I want a little vertical tip to prevent items from slipping off and a rounded end to make it smooth and safe. I'm hoping to avoid super complex curves, using basic cylinders and cubes to create a nice shape with the `difference()` function.

Could you design a parametric OpenSCAD file that lets me control all of those parameters and produces the hook design described? Also, I think it would be good to use `rotate()` to display the hook as shown, but it should be possible to remove that for ease of editing.

Hey, I've got this OpenSCAD code for a Baymax model, and I want to make an animation of him moving. I've got a bunch of variables in there for the angles and positions of different parts, but it's all static right now.

I need some help making it move! I'd like to see him do a little dance, maybe waving his arms and stepping from side to side. I'd like to specify the steps of the animation and the duration each step takes, or the timing between different movements, if you could make that parametric, that'd be great.

Can you generate the OpenSCAD files to achieve this? I'd like to control the movement via some new variables, like how far each limb moves and when these movements occur. So like, variables for start and stop times, and the position (or angle) at those times. And also, is there a way to make the movements smooth, instead of just jumping from one position to another?  I don't think I'm using any libraries currently, so you don't need to worry about including any.

Hey there, I'm looking for some help designing a replacement part for my tripod. It's a clamp that holds two leg sections together, and I'd like to create a parametric OpenSCAD file so I can easily adjust it for different tripod leg sizes and screw types.

Basically, the clamp has a cylindrical body that surrounds the larger leg. Then, it has a tab that extends out to the side, with two screw holes to tighten the clamp around the smaller leg. I've attached a basic OpenSCAD file that has worked for me but I'd like to see it designed from scratch by an AI. I would prefer a design that uses the BOSL2 library if that works, specifically for the bolts/screws aspect.

Here's a breakdown of the parameters I need to be adjustable:

*   **`diameter1`**: The diameter of the larger tripod leg (in mm).
*   **`diameter2`**: The diameter of the smaller tripod leg (in mm).
*   **`hole`**: The diameter of the screw holes (in mm).
*  **`nut`**: The size of the nut or hex head for the screws (in mm).
*   **`height`**: The overall height of the clamp (in mm).
*   **`thick`**: The thickness of the clamp body material (in mm).
*   **`gap`**: The space between the two halves of the clamp (in mm).
*   **`tab`**: The length of the tab section (in mm).

The clamp should consist of:
* A cylindrical body with a cut-out matching `diameter1` for the larger leg, using `thick` as the material thickness
* A cylindrical bore through the cylindrical body for the smaller leg matching `diameter2`.
* A tab that extends perpendicular from the main body, with a thickness of `thick`. The tab needs to be wide enough for the screw holes and the space for the nuts to be embedded within the material.
* Two screw holes, placed symmetrically on the tab using a variable `gap` as the space between them. The screw holes should accommodate a `hole` diameter.
* Spaces for the nuts to sit. The nut space needs to be a hexagonal cut-out using the nut parameter. These cutouts should also be symmetrically located with the screw holes.
* A cutout or slot to create two halves on the cylinder allowing it to clamp and compress. This slot needs to extend from the edge of the tab to the cylindrical bore for the smaller leg. There should be a similar slot on the opposing side as well.

I also need to be able to adjust parameters like the `height`, `thick`, `gap`, and `tab` as these will be important for testing. I'd like for everything to be designed parametrically.

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

Hi, I'm looking for an OpenSCAD design for a pen holder that's shaped like an hourglass. I'd like to be able to customize the number of pen holes, their diameter, and optionally add a center hole or a center bowl.

Here are the specifics:

1.  **Hourglass Shape:** The main body should have an hourglass silhouette. I like the design in `Penholder.scad`. It's got a good "pinched" waist and flared top and bottom.
2.  **Pen Holes:**
    *   I need to be able to specify the number of pen holes. The user should be able to choose from at least 6, 7, 8, 9, 10, 11, and 12 holes.
    *   The diameter of the holes should be customizable too, with options like 8.5mm (small), 10mm (medium), and 11.5mm (large).
    *   The holes should be arranged evenly around the circumference, near the top of the hourglass portion.
3.  **Center Hole:** It should be an optional feature to add a single hole in the very center of the top, for pens/pencils.
4.  **Center Bowl:** I'd like to have the option of adding a bowl in the center of the top.
    *   The bowl's depth should be customizable, with a user setting for bowl depth between 5 and 15 mm.
5.  **Dimensions:** I like the overall dimensions from the example `Penholder.scad`. The total height is roughly 70, the top/bottom radius is about 26.4, and the pen holes are located with a radius of 28.
6.  **No Overhang Support:** I'm using a 3D printer, so the design needs to be printable without any support material, like in the example `Penholder.scad`.

Could you generate a parametric OpenSCAD file for this? I don't need any special libraries, just regular OpenSCAD primitives. Thanks!

Hey, I'd like to design a customizable spinning top, and I'd like to be able to generate all the parts for printing separately, or combined for a single print. I want to be able to vary the diameter of the disc part, the overall height of the top, and the thickness of the stick or handle, and to have it lock securely so it doesn't come apart.

Here's the basic concept:

*   **Two Main Parts:** A disc-shaped top and a handle/stick that fits into it.
*   **Locking Mechanism:** The handle should have a wider section that locks into a cutout inside the disc when assembled. I'd like to be able to add some wiggle room for the fit using a parameter.
*   **Disc:** The disc will have a rounded shape, where the top is a smaller diameter than the bottom, giving it a slight conical profile, sort of like a spinning top with a rounded disc.
*   **Handle/Stick:** The handle will be cylindrical with a lock near the top that's a simple rectangular cross-section piece that fits inside the disc. I want to specify the width of this locking area relative to the handle itself.
*   **Numbers:**  If the disc has a number of sides less than or equal to 20, I'd like to have the option to imprint numbers around its circumference (like on a dice) using the "write" library. If you can do that I'd like to adjust the size and offset of the numbers.
*   **Output Options:** I want to be able to output different versions of the design: just the disc, just the stick, the assembled top, and also separate versions optimized for printing: the stick oriented horizontally and the disc with the flat part down.
*   **Font:** For the numbers, use the "Orbitron.dxf" font which is also in the "write" library.

Here are the specific parameters I'd like to control:

*   `part`: A string, choose from "disc", "stick", "all", "printstick", "printdisc", "printall".
*   `print_numbers`: Boolean to turn the numbers on or off.
*   `numbers`: Integer - number of sides (and therefore numbers) if `print_numbers` is enabled.
*   `wiggle`:  Amount of clearance between the stick and the disc's hole.
*   `totalheight`: Total height of the assembled top.
*   `disc_diameter`: Maximum diameter of the disc.
*  `disc_percent_smaller`: Percentage to reduce the top disc radius relative to the bottom.
*   `stickw`: Thickness of the handle/stick.
*   `stick_stop_width`: How much wider the lock part of the stick is than the stick itself.

I guess that's it? Let me know if you need more info. I don't have a preference of units; using mm is fine.

[Assistant]
top_v8.scad:
```
//Select an STL part to generate.
part = "printall"; // [disc,stick,all,printstick,printdisc,printall]

//Should numbers be printed on top to use it like a dice? It works only until 20...
print_numbers=1; //[0,1]

//disc with numbers to replace a dice, set it to maximum 20. If set to e.g. 32, it will be rather round.
numbers=32;

//The space around the middle stick to make it fit snugly into the disc
wiggle=.25;

//Height of the top in mm
totalheight=25;

//width of the top's round mass
disc_diameter=30;

//shrinking percentage for the top's round mass
disc_percent_smaller=0.75;

//stick thickness in mm
stickw=2.6;

//stick stop lock width adder in mm
stick_stop_width=1.5;

I'd like a parametric OpenSCAD design for a customizable key chain or tag, similar to the provided example but with a more flexible and robust parameter set.

Here's what I need:

**Core Functionality:**

*   **Text Input:** The design should be able to handle multiple lines of text, ideally up to 4, but a variable number might be useful. Each line should be individually customizable.
*   **Text Alignment:**  I'd like to control the horizontal alignment of the text (left, center, right) within the bounding box of the label.
*   **Font Selection:**  It should use an external font file (like the dxf fonts in the provided example), and I should be able to specify the font file to be used. I'm hoping the design can handle any dxf fonts. The design should handle scaling to the user-defined text height and handle spacing, as in the given example.
*   **Base Plate:** A rectangular base plate with customizable rounded corners and an adjustable outline border/frame.
*   **Attachment Lug:** An optional key chain lug that's a cylinder, with a hole through the center, and a tab or reinforcement. The diameter and position of the lug should be adjustable.
*   **"Cross Out" Stroke:**  An optional diagonal line or "X" across the label.  The style (line, X) and thickness of this stroke should be adjustable.

**Parameters:**

*   **Text:** Individual strings for each text line
*   **Alignment:** Integer selection for text alignment (left=0, center=1, right=2)
*   **Build Lug:** Boolean to include/exclude the key chain lug
*   **Hole Diameter:** Diameter of the hole in the key chain lug
*   **Stroke Style:** Selection for no line/cross, a single forward slash, a back slash, or a full X
*   **Stroke Width:** Width/thickness of the "cross out" stroke
*   **Base Plate Rounding:** Radius of the rounded corners of the base plate
*   **Base Plate Outline:** Thickness of the border around the base plate.
*   **Text Font:** File name of the font to use (e.g., "knewave.dxf")
*   **Text Height:** Height of the text
*   **Text Space Factor:** Kerning factor to be used by Write.scad
*   **Line Space Factor:** Factor to be used by Write.scad
*    **Base Plate Level**: Z height of the main plate
*    **Base Plate Outline Level**: Z height of the base plate outline
*   **Stroke Level**: Z height of the stroke
*   **Text Level**: Z height of the text
*    **Lug Level:** Z height of the lug

**Additional Considerations:**

*   The design should be suitable for multi-color printing by layering different heights (e.g., text is raised above the base plate).
*   It should use the `Write.scad` library for handling the text.
*  The dimensions of the base plate should automatically adjust based on the size of the text and the rounding radius.
*   I'd like good parametric control to allow me to easily adjust sizes and features.

I'm looking for the design to be flexible and not locked into the exact sizes as in the example. I'm also not looking for an exact copy of the provided design; it's just a good starting point for the type of thing I want.

[User]
Okay, I'm looking to design a customizable flange for mounting a wheel or similar component onto an axle, and I'd like it to be parametric and generated as OpenSCAD files. Here are the details:

**Core Functionality**

The main goal is to create a flange with a central hole for an axle, a series of mounting holes on the flange itself, and a "finger" or hub that will fit into the bore of a wheel or other component. The design needs to be configurable, with all dimensions easily adjustable via parameters.

**Parameters:**

I want to control the following dimensions, and I'd appreciate it if you could make them named parameters in the code:

*   **Axle:**
    *   `axle_diameter`:  The diameter of the axle the flange will mount on. This can be a value like 6mm, but should be adjustable.
    *   `axle_thickness`: The thickness of the axle. It's a kind of 'flattening' parameter for a D-shaped axle, and if this value is less than the diameter the axle will have a D shape.
    *   `axle_length`: Length of the axle mounting portion.
*   **Hub/Center Bore:**
    *   `hub_diameter`: The outer diameter of the hub that surrounds the axle mounting portion.
*   **Flange:**
    *   `flange_height`:  The thickness of the flange.
    *   `flange_holes_number`:  The number of radial mounting holes in the flange.
    *   `radial_holes_r_vector`:  The radius at which the mounting holes are positioned on the flange.
*   **Finger:**
    *   `finger_diameter`: The outer diameter of the finger that goes into the wheel bore.
    *   `finger_height`: The height/length of the finger.
*    **Screws and Nuts:**
    *   `screw_diameter`: Diameter of the screws to be used in the flange holes.
    *    `nuts_external_diameter`: The external diameter of the nuts to be used.
    *    `nuts_across_flats`: The distance across flats of the nuts to be used.
    *    `nut_height`: The height of the nuts to be used.
*   **Printing/Material:**
    *   `layer_thickness`: To help with print accuracy, dimensions should be calculated based on the layer thickness. I'd like this to be an adjustable parameter.
    *   `shell_thickness`: Thickness of the solid outer shell of the printed object, so it can have structural integrity.
    *   `build_plate_selector`: For visualization, this will choose a specific common build plate size, but it should not effect the final object, the size of which should be determined exclusively from the parameters above.
    *   `build_plate_manual_x`: The x dimension of a manual build plate.
    *   `build_plate_manual_y`: The y dimension of a manual build plate.
*   **Smoothing**:
    *   `$fa`, `$fs`, `$fn` : For smoothing the model

**Key Design Aspects:**

1.  **D-Shaped Axle Option:** The flange should accommodate both round and D-shaped axles. The `axle_thickness` parameter will determine if it has a flat side, and how large.
2.  **Layer Alignment:** Dimensions should be calculated such that vertical dimensions are multiples of the `layer_thickness`, ensuring clean printing.
3.  **Automatic Tolerance:** I’d like a small tolerance to be built into certain parts, specifically the axle hole and the "finger" that fits into the wheel bore.
4.  **Automatic Flange Diameter:** The flange diameter should be automatically calculated, based on the radial_holes_r_vector and the shell thickness.
5. **Nuts and Screws:** The nut and screw cavities should automatically be calculated based on their parameter dimensions, and positioned appropriately.
6.  **Build Plate Visualization:** I need to include the standard `build_plate.scad` and `utils/build_plate.scad` libraries. If `build_plate_selector` is set to "manual" the `build_plate` module will use the `build_plate_manual_x` and `build_plate_manual_y` parameters.

**Output:**

I am looking for a set of `scad` files that I can import into OpenSCAD. The primary file will define the module for the flange.

**Libraries:**
*   `build_plate.scad` (and its corresponding subdirectory)
I'd like to request the files be built from scratch, rather than modifying the code I've included.
