Okay, I'm looking for an OpenSCAD design for a customizable guitar pick. I need it to be parametric so I can easily adjust the thickness and add or remove grip features.

Here's what I'm thinking:

**Core Shape:** The basic pick shape should be created using a minkowski sum of a cylinder with another shape that looks like two cylinders intersecting with a third cylinder running perpendicular to the first two. This creates the basic pick outline with a smooth, rounded edge.

**Thickness:** I need to be able to specify the pick thickness via a parameter, probably called `z_thick`.  I want to have specific options for the following thicknesses that correspond with traditional guitar pick thicknesses, and each thickness needs a small text label on the pick:
    *   1mm (Extra Lite, labeled "XL")
    *   1.5mm (Lite, labeled "Lite")
    *   1.875mm (Medium, labeled "M")
    *   2.5mm (Heavy, labeled "H")
    *   3.75mm (Extra Heavy, labeled "XH")
    *   4.375mm (Extreme, labeled "X")

**Grip:** I want an optional grip feature.  I want a boolean parameter called `Grip`. If `Grip` is set to true (1), then two sets of grips should be added to the pick. The grips should be created by intersecting a few cylinders with a subtracted smaller cylinder to make a small grip notch on the top and bottom of the pick.

**Build Plate:** While I don't need a complex build plate for the main design, it would be good to optionally include a display build plate using the `build_plate.scad` library. I want to be able to select different printer options or a manual option which uses x and y parameters. The `build_plate.scad` library should be included.

**Text:** I want the design to utilize the `write.scad` library to add the "XL", "Lite", "M", "H", "XH", or "X" text labels on the face of the pick corresponding to the selected thickness. The `write.scad` library should also be included.

Can you provide an OpenSCAD file that incorporates all of these parameters and features?

Okay, I've been playing around with OpenSCAD and made a hat band clip, but I think I could make it a lot better with some help. I'm looking for a parametric OpenSCAD file for a hat band clip that can be customized in several ways.

Here's what I have in mind:

**Core Shape and Function:**
*   The clip should be a rectangular block that wraps around a hat band, like in the design of hatBandClip.scad. It should have a specific width and height, plus a thickness that determines how strong it will be.
*   The clip should have two main cutouts on each side to help it grip the hat band. They should be rounded, forming a kind of "C" shape on each side, and positioned symmetrically on the sides.
*   It should also have two raised parts that meet the cutouts, so it grips the hat band firmly.

**Customization Parameters:**
*   `hat_band_width`: The width of the hat band the clip is designed for.
*   `clip_width`: The overall width of the clip.
*   `clip_strengths`: The thickness of the clip.
*  `clip_border`: Space between the edge of the clip and the C cutouts
*   `number_of_feathers`: An integer value controlling the number of holes for decorative filaments (or "feathers"). This should be able to be from 0 to 5. The holes need to be slightly angled.
*   `text`: The text to be displayed on the clip.
*   `text_size`: The height of the displayed text.
*   `feather_diameter`: The diameter of the "feather" holes.
*  `negative_cylinder_diameter`: The diameter of the cutouts.
*  `positive_cylinder_diameter`: The diameter of the raised parts that grip the hatband.

**Text and Feather Holes:**
*   The text should be centered horizontally on the clip and placed vertically towards the front of the clip.
*   The feather holes should be centered horizontally on the clip, just above the text. The number and spacing should change when the `number_of_feathers` is changed. These holes should be angled slightly backwards, like in the previous design.
*   If `number_of_feathers` is 0, there shouldn't be any holes.

**Libraries:**
*   I'd like to use the `Write.scad` library for handling the text.

**Overall Goal:**
I want a design that is easily customizable and that I can 3D print. It should have a functional design and look good with "filament feathers" inserted into the holes and with different text. I want to be able to make different clips for different hats, teams, events, etc.

Could you generate an OpenSCAD file for me with these specifications?

Okay, I'm looking to design a customizable zoetrope that I can 3D print. I've got a rough idea of what I want, and I've even got some existing OpenSCAD code that kind of gets me there, but it's not quite as flexible as I'd like, and I'm hoping you can help me create a better, parametric version.

Here's what I'm thinking:

**Core Features & Parameters:**

1.  **Parts Selection:** I need to be able to choose whether I want to generate just the wheel, just the stand, or both. The existing code uses a `parts` variable with options like "both", "first", and "second" - maybe you could use similar strings for this.
2.  **Animation Frames:** I need a parameter to specify how many frames will be in the animation. The current code uses a variable `frames` for this, which works.
3.  **Frame Dimensions:** The animation frames will be rectangular. I want parameters for the width and height of each frame. I think the existing code uses `width` and `height`, which are fine.
4.  **Slit Depth:** There needs to be a parameter for how far the frames are pushed out from the center, this creates the slits. This is currently `slit` in the existing code.
5.  **Wheel Diameter:** I need a way to set the overall diameter of the wheel, while keeping the slit depth correct. The current code has an approach where you can scale the wheel, and it uses a `set_diameter` parameter (0 for no scale and 1 for scale) and a `diameter` parameter, but it's clunky. It would be better if I could just specify a `wheel_diameter` and have the code calculate the correct overall size including slits.
6.  **Stand Height:** A parameter is needed for the height of the stand (distance from the ground to the axle) for the overall stand height. The current code uses `stand_height`.
7. **Axel Diameter:** The diameter of the axle needs to be specifiable, this is not currently exposed in the provided code.

**Structural Details (Considerations):**

*   **Wheel Construction:** The wheel needs to have a solid backing and clips to hold the animation frames in place. I like how the current code uses a combination of cubes to accomplish this. Also there needs to be a central hub with mounting holes.
*   **Stand Design:** The stand should be stable with a base, upright supports, and a location for the axle. It also needs to include the knob and the arm for spinning the zoetrope.
*   **Parametric Calculations:** I'd like the wheel's radius to be calculated correctly based on the frame height, slit depth, and number of frames. The current code is able to do this, but I want it tied to a simple `wheel_diameter` parameter.
*   **Material Thickness:** I'm going to print this on a 3D printer so I should be able to specify a general parameter for material thickness so it can be varied.

**Desired Improvements over Current Code:**

*   **Direct Diameter Control:**  I want to set the wheel diameter directly and have the code calculate the rest, rather than the scale method in the current code.
*   **Clearer Parameter Usage:** I'd like the parameter names to be very clear and easy to understand.
*   **Better Comments:** I'd love it if the code could be well-commented to explain what each section does.
*   **More Precise Hub and Axle:** The hub should fit the axle more precisely. The axle diameter should also be an input, and the hole needs to be slightly bigger for a friction fit.

**OpenSCAD Libraries:**

I don't think I need to use any additional libraries for this, just the built-in OpenSCAD functionality should suffice, but if you feel there's a specific library that would make this design easier, let me know.

Essentially, I'm looking for a parametric OpenSCAD model that will allow me to fully customize the zoetrope to my needs. Let me know if you have any questions.

Okay, I'm looking to create a customizable wax seal stamp generator in OpenSCAD, and I'd like it to be parametric so I can easily adjust various aspects. I've been playing around with a similar design but I'm looking for a cleaner implementation and some improvements.

Here's what I need:

**Core Functionality:**

1.  **Stencil Input:** The design should accept an array of 2D points (like the `points_array` in my example), which define the outline of the seal design. This array will be the output from a stencil generator, similar to Benjamin's Stencil-o-Matic tool. I need to be able to easily paste this array into a variable. I'm expecting that the first element in the array is the width and height, then the remaining elements are paths to extrude.
    *   A "default" test case should be included in the code if no stencil data is provided, similar to the `input = "default_TNH"` conditional.
2.  **Seal Resizing:**  I need a parameter to control the overall size of the seal design. Ideally, this would scale the stencil proportionally without affecting its shape, with a variable, `seal_size` controlling this scaling, similar to my example.
3.  **Seal Movement:** Parameters to move the seal design left/right (`Move_X`) and up/down (`Move_Y`).
4.  **Handle Choice:** I want two handle options: "large" and "small". The "large" handle should have a tiered, decorative look, similar to the current example, with a cylindrical base, and then some concentric cylinders to form the handle. The "small" handle should be more basic, using a simple cylinder with a cube for a handle grip.

5.  **Orientation Indicator:** An orientation marker, like a small triangle, on the stamp face, so the user knows the orientation of the stamp design when pressing it into wax. This needs to be part of the handle, not the seal itself.
6.  **Quality Control:** A variable to control the `$fn` of all the circles, using the same `quality` variable as my example.
7. **Extrusion Thickness:** A variable, `stencil_thickness`, to control how thick the extruded stencil design is.

**Libraries:**

I'll need the `Write.scad` library for the text on the handle, and the `triangles.scad` library from `MCAD` for the triangle orientation indicator.

**Output:**

The output should be an STL file when I render the project with the "print quality" setting selected. The user shouldn't need to explicitly specify output parameters.

**Structure:**

I'd prefer the code to be structured with clear module definitions for each part:

*   A `stamp()` module for the "large" handle.
*   A `stamp_small()` module for the "small" handle.
*   A `pattern()` module that extrudes the pasted in paths.
*   A top-level conditional that selects the correct module based on `handle_size`.

**Initial Settings (for testing):**

*   `quality` = 25 (for draft quality, then change to 200 for print quality)
*   `handle_size` = "large" (as the default)
*   `input = "default_TNH"` (as the default).
*   `seal_size` = 10 (as the default)
*   `Move_X` = 0 (as the default)
*   `Move_Y` = 0 (as the default)
*   `stencil_thickness` = 1.5 (as the default)
*   `margin` = 10 (as the default)

**Additional Notes:**

*   Please make sure the text on the handle is centered. I'd also like it rotated 90 degrees when the small handle is selected.
*   The orientation triangle on the handle should point towards the top of the design when printed.
*  I need to make sure that the top-level conditional applies the `pattern()` module, to the handle selected based on the `handle_size` parameter, so it is cut out of the end of the handle.

I think that's everything. Let me know if you have any questions, and I'm excited to see what you come up with.

Okay, I need a customizable golf ball marker. I want to be able to change a few things like the size, the height of the little spike that goes into the green, and what letters are on it.

Here's the breakdown:

*   **Overall Shape:** It should be a flat, circular disc with a small spike coming out of the bottom, kind of like a tiny mushroom.

*   **Diameter:** I need to be able to set the main diameter of the disc, say from 10 to 20 mm. I’d like to call the variable `marker_diameter`.

*   **Spike Height:** I also need to adjust how long the spike is, maybe between 5 and 8 mm. This variable should be `spike_height`.

*   **Initials:** I want to put my initials on the marker, and the letters should be engraved *into* the top of the disc. I should be able to type whatever letters I want; let's call this variable `initials`.

*   **Letter Height:** I need to specify the height of the letters as well. Let's start with a range of 9 to 13 mm, with the variable name `letter_height`.

*   **Letter Style:** It’d be great if I could choose between two letter styles: "fancy" and "plain", the variable should be called `letter_type`.

*   **View/Print:** I need to flip the model so I can view and customize the text on the top surface, and flip back for printing. I think a value of 180 degrees on the X or Y axis will work. The variable should be named `flip_model_to`, and use 180 for viewing and 0 for printing.

*   **Libraries:** It should use the `Write.scad` library for generating the text. That file has an included folder called `write`, so it should refer to `write/BlackRose.dxf` and `write/Letters.dxf` for the fonts.

Could you generate the OpenSCAD code for this?

Okay, I'm looking to design a more flexible gasket generator in OpenSCAD, but I need some help making it more powerful and easier to use. I really like the existing "gasket.scad" example, and it gets me most of the way there, but it's missing some features and flexibility.

Here's what I want the new gasket generator to be able to do:

1.  **Variable Thickness:** Like the existing file, I need to be able to set the gasket thickness as a variable, say `gasket_thickness`.

2.  **Inner and Outer Diameters:** I also need to specify the inner and outer diameters, `gasket_inner_diameter` and `gasket_outer_diameter` respectively, just like the original.

3.  **Variable Bolt Holes:** I want to add the ability to generate bolt holes around the perimeter of the gasket.
    *   The number of bolt holes should be variable, say `num_bolt_holes`.
    *   The bolt hole diameter should also be variable, `bolt_hole_diameter`.
    *   The distance of the bolt holes from the center should be variable, `bolt_hole_radius`, and this value should be larger than the `gasket_inner_diameter` and smaller than the `gasket_outer_diameter`
    *   The placement of the first bolt hole should be set with a rotation angle, `bolt_hole_start_angle`. This will allow easy alignment of bolt holes to external parts.

4.  **Rounded Edges (Fillet):** I'd like to add a fillet to the top and bottom edges of the gasket. The fillet radius should be variable, `fillet_radius`. I think this will be a cosmetic improvement as well as improve the seal

5.  **Cutout Shapes:** Ideally, I would be able to add cutout shapes anywhere on the surface of the gasket, using basic 2D shapes like squares or circles. This would allow for complex seal patterns or accommodate obstructions. The cutout shapes would have their own customizable dimensions and positions.  This will probably require some kind of `cutout_shapes` array or something like that.

6.  **Parametric Cutout Placement:** I want to be able to place these cutout shapes parametrically.  I should be able to define the cutout shapes and a number, an angle offset (like how we did the bolt holes), a radius offset, and a repeat count. This will allow me to create circular repeating patterns like for the bolt holes.

7.  **Support for `$fn`:** The generated part should support the global `$fn` variable to control the smoothness of circles and curves.

I'm not looking for anything super advanced in the cutout shapes for now (just circles and squares); I can expand on that later. The most important thing for me is that this generator be easy to use and allow me to quickly create custom gasket designs with different sizes, bolt holes, and a few custom cutouts. The idea is that I'll ultimately use a caulkstruder to make these.

Can you generate an OpenSCAD file for this? I would also prefer if it uses the BOSL2 library.

Okay, I'm trying to make a simple rocket model using OpenSCAD, and I want it to be customizable. I've already got a basic file that kinda works but it's a bit clunky and I think could be done better.

Here's what I'm envisioning and what my current code does:

*   **Basic Shape:** The rocket body is a cylinder with a rounded top (a sphere scaled and translated).
*   **Fins:** It has four fins equally spaced around the base. The fins are triangular, and their size is adjustable, and they are attached with linear extrusions.
*   **Dimensions:** I need to control the height and diameter of the main body.
*   **Scale**: I need to control scaling for the fins and entire model.
*   **Customization:** I want to adjust all dimensions, scale of the fins, and scale of the model through customizer sliders.

Right now I'm using these variables, as you can see in the provided file:

*   `numerical_slider_1`: This controls the rocket's height. I'd like a range from 60 to 1000.
*   `numerical_slider_2`: This controls the rocket's diameter (radius). The range should be from 2 to 100.
*   `scale_wings`: This controls the size of the wings. I want this as a percentage slider ranging from 50 to 3000.
*   `scale_model`: This is supposed to scale the entire model, but not the fins. I want this as a percentage slider.

The current code uses `difference()` to remove an extremely large cylinder, just in case something goes wrong, but I think there are more elegant solutions available.

Can you help me write a more parametric OpenSCAD file that has:

*   Clean structure for parameter input.
*   Adjustable rocket body (height and radius).
*   Adjustable fins (size, using the existing triangular shape).
*   Ability to easily scale the fins and entire rocket model.
*  A cleaner way to ensure the base is trimmed, or remove the base-trimming cylinder.

I am not using any libraries beyond the base OpenSCAD, so no extra libraries are needed.

Okay, I'd like to create a customizable message band, kind of like a bracelet, using OpenSCAD. I've seen some examples, and I'd like it to be elliptical in shape, with a message wrapped around the outside. I have a working example, but I want to make it more parametric and have better control over the text and size.

Specifically, I want these parameters to be customizable:

*   **`band_a`**: This is the major radius of the ellipse, like the width of the bracelet, measuring the wrist horizontally.
*   **`band_b`**: This is the minor radius of the ellipse, like the thickness of the bracelet, measuring the wrist vertically.
*   **`band_width`**:  The overall width (thickness) of the band itself (how much it sticks out from the wrist).
*   **`thickness`**: The thickness of the band material (how deep the band is).
*   **`message`**: The text to be displayed around the band.
*   **`font`**: The font to be used for the message, which should come from the `Write.scad` library included in the code I saw. This library allows specifying fonts from .dxf files (e.g. "write/orbitron.dxf").
*   **`font_size`**:  The height of the letters. This I might specify relative to the band width.
*   **`$fn`**:  The number of segments for the rotational extrusion, which should affect the smoothness of the band's curve. I'm okay with keeping a default, but I want to be able to change it.

My example code uses `rotate_extrude` to create the main elliptical band shape, and then uses `writecylinder` from the `Write.scad` library to add the message. I like that approach but I would like the `writecylinder` to have the font size be specified directly without calculating based on the band width (unless the user chooses to do so). The code I was using also had a couple of hardcoded scaling factors I would like replaced with parameters. The way the message sits on the band is fine, but I want to be able to control how far the text sits from the surface of the band (which was not included in my example code).

I'd also like the option to change the alignment of the text if possible, rather than the default center alignment.

I'd really appreciate an OpenSCAD file that encapsulates these parameters and gives me full control over the band's dimensions, the message, the font, and the text placement. The use of the `Write.scad` library is essential for the text functionality so don't remove that. The code should be well documented with clear comments and the variable names should match the description above. I will provide my own copy of `Write.scad` so that is not necessary.

Okay, I need some help designing a customizable heel lift for my shoes. I'm looking to make something that I can adjust for different needs and that I can 3D print. I've seen some designs out there, but I'd like something a bit more parametric so I can tweak it to fit perfectly.

Here's the basic idea: I need a wedge-shaped piece that fits under the heel. The width of the heel area will be a key variable, which I'll need to adjust to fit different shoes. The length of the wedge extending past the heel will also be adjustable, as will the height at the front of the wedge, and the overall angle of the wedge, because some people need more of a lift than others.

I’d like the design to be based on a few specific parameters.  I need to be able to specify the heel width, the length of the wedge past the heel, the height at the front of the wedge, and the wedge angle. This should be a pretty standard wedge, and I don't anticipate needing to do anything too fancy like rounded corners in the first iteration.

To be clear, I need the following to be *parameters*:

*   `heel_width`: The width of the heel in millimeters. I’m assuming this will be for a flat footbed, and that the radius of the “circle” that forms the back of the wedge will be calculated from this value by dividing it in half.
*   `l`: The length of the wedge extension past the heel in millimeters.
*   `h`: The height at the front of the wedge in millimeters.
*   `wedge_angle`: The angle of the wedge in degrees.

The design should be in OpenSCAD and should be easy to modify using these parameters, so please avoid any hard coded values other than for very minor and specific offset needs.

I would prefer if the OpenSCAD file is clear and well-commented so that I can understand how the code works, and how to change it if needed later. I’m not interested in any libraries other than the basic capabilities of OpenSCAD.

Can you help me generate this OpenSCAD file?

Okay, so I'm looking to get a customizable cable tie designed in OpenSCAD. I want to be able to adjust a bunch of parameters, like the overall length, the width and thickness of the tie itself, and whether or not it has a screw hole in the head or a release tab for the pawl.

I'd like the design to use a gear-like mechanism for the tie and pawl engagement. The tape part of the tie should have recesses to catch the pawl. The head should have a guide for the tape as well as a cutout for the pawl. I want to be able to set the number of teeth for the pawl. The head should have rounded corners on the outside.

For the leader, I need to include a tapered end for easy insertion, as well as some small retainers along the edges. A fillet where the tape meets the leader would be nice, too.

I'd also like to be able to print multiple of these at once and have them arranged on the build plate correctly for printing.

For the measurements, I want to define tape width and thickness as main parameters. Also, I'd like to use a tape scaling parameter based on nozzle diameter (like `tapeScale` in the example) to control some other dimensions, which helps with printer accuracy.

Specifically, I need to be able to adjust:
*   **`length`**: The overall length of the cable tie.
*   **`screwHole`**: A boolean to include a screw hole in the head.
*   **`releaseTab`**: A boolean to include a release tab on the pawl.
*   **`tapeWidth`**: The width of the main tie.
*   **`tapeThickness`**: The thickness of the main tie.
*   **`tapeScale`**: A scaling factor based on nozzle diameter.
*   **`partCount`**: The number of cable ties to print at once.
*   **`build_plate_selector`**: A way to choose standard build plates or manual dimensions for printing multiple parts.
*   **`build_plate_manual_x`**: The x-dimension of the build plate, if `build_plate_selector` is set to manual.
*    **`build_plate_manual_y`**: The y-dimension of the build plate, if `build_plate_selector` is set to manual.

I'd like the code to have a `build_plate.scad` library, and it should use the `build_plate` module to set up the build plate for printing.

Can you create a complete parametric OpenSCAD design that includes these features?

Okay, I'd like to design a customizable tray grid for organizing small parts. I need an OpenSCAD file that allows me to specify several parameters to control the grid's dimensions and features.

Specifically, I need to be able to define:

*   **Overall Height:** The total height of the tray grid. This will be a single value for all the trays.
*   **Tray Width & Depth:** The interior width and depth of each individual tray in the grid. All trays will have the same width and depth.
*   **Number of Trays (X & Y):** I need to specify how many trays are in the x direction (going across) and how many in the y direction (going down)
*   **Wall Thickness:** The thickness of the walls surrounding each tray and also the outer walls. All walls are the same thickness.
*   **Corner Radius:** The radius of the rounded corners on both the inner and outer edges of the entire tray grid. It's important that these are well-defined and consistent.
*   **Resolution:** The resolution of the curves (or $fn) needs to be settable.

The final output needs to be a solid object that represents the tray grid with all the features described above. So it should look like a grid of rectangular trays enclosed by an outer wall. The internal pockets should have the dimensions of the "Tray Width" and "Tray Depth".

I need to be able to adjust all these parameters to generate different size grids. I'd like to have reasonable default values, but all those parameters need to be customizable.

I would like you to use the `offset` command to create the outer wall, that is important for my design. I do not need to use any OpenSCAD libraries for this design, just the built-in functions.

Could you generate that OpenSCAD file for me?

Okay, I'd like to design a parametric case generator in OpenSCAD. I've seen a design that does almost exactly what I want, but I'd like to take it a little further and also have more control over the overall design.

The basic idea is to create a box that is built up from flat pieces that are joined using T-slots and screws. I'll give you some parameters and I'd like the design to be parametric based on those.

Here's what I want to be able to configure:

*   **Internal Dimensions:** The internal X, Y, and Z dimensions of the case, so it can fit whatever I want to put inside.
*   **Material Thickness:** The thickness of the material used to make the case. This will be the thickness of the walls.
*   **Screw and Nut Dimensions:**
    *   Outside diameter of the screws.
    *   Length of the screws.
    *   Outside diameter of the nuts.
    *   Height of the nuts.
*   **Anchor Configuration:** The "anchors" are the T-shaped parts that will be pushed into the opposing face of the case.
    *   Number of anchors on each face.
    *   Width of the "teeth" of the T-shape.
    *   Position of the nut within the channel for the screw, expressed as a percentage of the channel height.
*   **Part Selection:** I need to be able to select which parts to generate. I'd want to generate each wall individually, or all of them together in an assembled form, as well as a "milled" version. The milled version lays the parts out flat for cutting on a CNC or laser cutter. I'll also want the ability to preview each of the individual walls.
*   **Overall size**: The case should be slightly bigger than the interior to accommodate the material thickness
*   **Wall Height**: The walls should all be the same height as the interior Z dimension

The case will be made up of a bottom, top, and four walls (north, south, east, and west). The bottom and top should be a simple rectangle that encloses the sides and are joined to the sides. Each of the four walls will have the same number of T-shaped "anchors" along each edge.

The basic design is as follows: the walls have a series of T-shaped extrusions (the "anchors") along the edges. The top and bottom parts have a corresponding set of matching T-shaped channels (the "harbors") to receive these extrusions. The screws go through a hole on the wall piece, and into the channels of the top or bottom piece, which are sized such that the screw holds the two pieces together. I'd like the nut to be trapped within the channel in the top or bottom piece, in a way that allows it to be easily placed without falling out, but also be locked in place by the screw.

I'd also like to make sure that the anchor points along each wall can be offset, or moved closer to or further from the edges, so that we can adjust where the screw joins the mating wall.

I'd like to have it so that these values are all configurable, such that I can easily adjust it in the customizer menu for OpenSCAD.

Finally, I'd like the design to use the MCAD library, specifically for the `projection` command which helps create the flattened "mill" layout. I'm not using any other libraries, though feel free to offer an alternative if you think it would be useful.

Okay, so I'm looking for a parametric button design, something I can easily customize. I came across this "Uni-Button" concept, and I really like the basic shape, but the original code is kinda messy, hard to understand, and not very parametric.

Basically, I want a button that has a rounded top and bottom, connected by a cylindrical middle section. The key is that I want to be able to control the overall size of the button, the outer radius, and maybe the height of the middle cylinder. I'd like to have small holes equally spaced around the perimeter for attaching it to something, and they should also have these rounded, bulbous, 'filled in' sections, so it doesn't look like the holes go all the way through.

So to be very specific:

*   The basic button form should be a rounded top, a cylindrical middle section, and a rounded bottom (like a pill shape or a squashed sphere).
*   The button should have four small mounting holes, evenly spaced around the circumference of the cylindrical middle.
*   Each mounting hole should have a rounded section that extends outwards on each side. This rounded part should be mostly embedded into the button, not a complete sphere.
*   I want to be able to adjust the *overall scale* of the button.
*   I need to be able to adjust the *outer radius* of the button.
*   I should be able to control the *height* of the cylindrical middle section.
*   I'd also want to be able to adjust the *radius of the mounting holes*.
*   I also need to be able to adjust the radius of the rounded, bulbous sections that fill out the holes.
*   I also need to adjust the position of the bulbous fill sections along the z axis.

Could you generate me an OpenSCAD file that handles all of these things parametrically, maybe with some comments to make it easier to understand? I don't need anything fancy, just a single .scad file. I'm not using any external libraries for this.

Okay, I'm looking to design a simple furniture foot, like what you might find on a chair or small table. I'd like it to be parametric so I can easily adjust its dimensions.

Here's what I have in mind:

*   **Basic Shape:** The foot should be a truncated cone, wider at the top than the bottom.
*   **Height:** I need to be able to control the total height of the foot.
*   **Top Width:** I need to control the diameter of the top circle of the cone.
*   **Bottom Width:** I need to control the diameter of the bottom circle of the cone.
*   **Mounting Hole:** It needs a central hole going all the way through for mounting it to the furniture, like for a screw or bolt. I need to control the diameter of this hole.
*   **Countersunk Head:**  I also need to create a countersunk section at the top of the hole, so the screw or bolt head will sit flush with the top of the foot. This countersunk needs to be defined by its height and diameter.

I want to be able to adjust all of these dimensions easily. Could you create an OpenSCAD file for this, using parameters for:

*   `FootHeigth` (Total height of the foot)
*   `TopWith` (Diameter of the top of the cone)
*   `BottomWith` (Diameter of the bottom of the cone)
*   `HoleDiameter` (Diameter of the mounting hole)
*   `HeadHigth` (Height of the countersunk area for the screw/bolt head)
*   `HeadWith` (Diameter of the countersunk area for the screw/bolt head)

Please include comments in the code so I can understand how it's working.

I am not using any libraries at the moment.

Okay, so I'm trying to design a parametric battery adapter. I've already got a basic OpenSCAD file that creates the main body with two contact pins for a battery, but it's not really user friendly and doesn't include any housing for the electronics.

Here's what I need:

**Basic Functionality:**

*   **Parametric Battery Size:** The adapter should be able to accommodate batteries of varying sizes (width, length, and thickness). The current file has `BatteryWidth`, `BatteryLength`, and `BatteryThickness` parameters, and I'd like to keep those.
*   **Contact Pins:** The adapter should have two contact pins for the battery terminals. My current design uses nail heads as the contact points. I have `PinThickness`, `PinHeadThickness`, `PinHeadDepth`, `Pin1DistanceFromEdge`, and `Pin2DistanceFromEdge` parameters, and I'd like to keep those as well.
*   **Wire Routing:** There should be a hole or channel to route wires out of the adapter. I have a `WireWidth` parameter for the hole size, I want this to stay, and have the wire routing go to an opening for the electronics bay as described below.

**New Features and Modifications:**

*   **Electronics Bay:** I need a space to hold a small buck converter. This should be a rectangular cavity on one side of the battery adapter and should have parameters for its width, length, and depth. I'd like to call these `ConverterBayWidth`, `ConverterBayLength`, and `ConverterBayDepth`. This bay should be on the *opposite* side of the battery from the contact pins.
*   **Enclosure for the Electronics:**  I'd like an enclosure for the converter bay, effectively a lid. I think it would be nice if the lid had a lip so it can friction fit into the converter bay, making it simple to close.  The lid should be a separate part, so it can be printed separately. It needs a parameter for the lip thickness, `LipThickness`. The enclosure should have a parameter that is the same as the lip thickness, `LidThickness`. The lid should be flush with the overall dimensions of the adapter when inserted.
*   **Mounting Holes:** It would be useful to have the option of adding mounting holes so I can attach this to something. Ideally, these should be configurable – number of holes, hole diameter, and distance from the center of the battery block. I'd like parameters for `MountHoleCount` (1, 2 or 4 allowed), `MountHoleDiameter`, and `MountHoleDistance`.  I would like the mounting holes to be located on the opposite side of the contact pins, and on the 'front and back' or 'side' of the adapter (depending on orientation of the adapter's longer dimension).
*   **Rounded Corners:**  I think it would make the design look nicer and more printable if the corners on both the battery adapter and the lid were rounded. This would be a single radius value parameter, `CornerRadius`.

**Constraints:**

*   **Parametric Design:** The design must be fully parametric, meaning all dimensions should be controlled by parameters that can be easily changed.
*   **Printability:** The design should be printable on a standard FDM 3D printer. No excessively thin features or overhangs.
*   **OpenSCAD:** The design must be in OpenSCAD.
*   **MCAD library:** Please use the `involute_gear()` module for the screw holes from the MCAD library. Do not include the library itself, as I already have it.
*   **No other external libraries:** I'd like to keep things as simple as possible and not add any other dependencies.

**Current File:**

I've attached my current OpenSCAD file to this request. (I'm pretending to do this, I know that you don't get to look at it!).

**In short, I want you to take my simple OpenSCAD file and enhance it to be much more complete and useful.**

Can you create a new, parametric OpenSCAD file that includes these features? Let me know if you need any clarification.
