I need an enclosure for an FG085 signal generator. I've got some measurements in mind and some ideas about how it should be constructed. I'm hoping you can generate the OpenSCAD files for me.

Essentially, the enclosure will sandwich the signal generator's front panel and circuit board between two halves. The front panel is the main visible face, so the enclosure needs to fit snugly around it. The circuit board sits behind that and is connected to the front panel with some standoffs. The overall design should result in a box, with the enclosure pieces bolted together. The front and rear panels of the unit are fixed in place in this design and are not part of the enclosure itself.

Here are the dimensions and features I'm thinking of:

*   **Overall Dimensions:**
    *   The front panel is 157.5mm wide and 62mm tall.
    *   The enclosure walls should be 2mm thick.
    *   The sides of the front panel have a slight curve; I need an extra 1mm added to the width of the enclosure sides at the midpoint to account for this curvature on each side.
    *   The PCB is 6.1 inches (154.94mm) wide, 2.2 inches (55.88mm) tall and 1.6mm thick.
    *   The PCB is located behind the front panel, and I have two standoffs, one 12mm long in front of the PCB and the other 13.2mm behind the PCB, placing the PCB a distance of 12mm+1.6mm+13.2mm = 26.8mm behind the front panel.
*   **Mounting:**
    *   I want to use M3 screws for assembly with 3mm threads. I'll need clearance for the nut (approx 5.3mm dia) at the rear panel. The screws are located 144.3mm + 3.6mm = 147.9mm apart in the X direction and 44.8 + 3.6mm = 48.4mm apart in the Y direction.
    *   The nuts should be recessed into the rear panel.
*   **Connectors:**
    *   There's a power connector, with a 10mm diameter body, and it is located behind the pcb at a height of 6.2mm above the PCB surface, with the centre point at a distance of 0.5 inches below the horizontal mid-point of the PCB (in the Z dimension, assuming PCB is flat).
    *   There is a USB connector with an 11mm wide, 9mm high body at a height of 2mm above the PCB surface, with the centre point at a distance of 0.5 inches above the horizontal mid-point of the PCB.
    *   There are a few other connectors on the back: a PWM connector and two 5-pin headers. I'd like cutouts for these too. The positions are relative to the PCB centre.

        *   PWM: 3 pin, 0.8 inches below the middle of the PCB height, and 0.21 inches from the edge of the PCB width on the negative x axis
        *   U5P: 5 pin, same Z height as U6P and 3.5 inches from the edge of the PCB on the positive X axis
        *   U6P: 5 pin, 0.075 + 0.1 inches above middle of pcb height, and 2.675 inches from the edge of the PCB on the positive X axis.

    Note: All of these are offset slightly from the true edge of the PCB; I'd like to include these offsets. You can assume standard pin spacing (0.1 inches or 2.54 mm) for these connectors.

*   **Other:**
    *   I want a small amount of tolerance between the parts, call it 0.3mm. I want to use a nozzle that is 0.4mm, so design in some support (call it 0.4mm) for a print.
    *   I'd like a chamfer on the edges of the case. The chamfer depth should be 0.67 times the wall thickness of the case.
    *   I want some small (0.01mm) separation between the main pieces when assembled.
    *   I would also like the ability to toggle whether the cutouts for the connectors include the tubes for the connector parts or if they are cutouts with no tubes.
    *   I'd like to parameterize the shell construction as well to allow turning off the cutouts for the various connectors.
    *   I would like to be able to toggle off the screw posts, but they are on by default.

The design should be parametric, so I can easily change dimensions later if necessary. I think I will need a few modules, one for the main body, one for the screw posts, and one for the cutouts. I will need at least two files, one to store the parameters and modules, and one for main function calls. Please use comments in the generated code and avoid overly terse naming for functions and variables where clarity can be achieved without too much additional effort.

I think that's all I need for now. Let me know if you have any questions.

Okay, I'd like to design a battery storage tray that can hold both AA and AAA batteries. I've got a basic idea and some dimensions but I need it to be parametric so I can easily change the number of batteries stored, and also the size of the batteries, if needed.

Here are the details:

*   **Battery Types:** It needs to hold two types of batteries: AA and AAA.
*   **Arrangement:** I want to arrange the batteries in a grid-like fashion.  I need to be able to specify the number of rows and columns for both AA and AAA batteries separately.
*   **Wall Thickness:** There should be a wall around each battery hole, and also a base with a specified thickness.
*   **Clearance:** There should be a small clearance around each battery hole, maybe 0.5mm on the radius, to make it easy to insert and remove batteries.
*   **Base Height:** The base of the tray needs to have a defined height.
*   **Battery Height:**  The holes need to be deep enough to hold the batteries but this should also be a parameter that can be modified, since different brands might have slightly different dimensions.
*   **Dimensions:** For initial setup, lets assume that the AA battery radius is 14.5/2, and the AAA battery radius is 10.5/2. I want to also parameterize this, in case I need to change these later (or, even better, use existing OpenSCAD library values, if they exist), so that I don't need to measure them myself. Lets say the wall thickness for the grid is 2mm, base thickness is 5mm, and the battery hole depth is 30mm. Let's start with the initial counts of 4 vertical and 3 horizontal AA batteries, and 3 vertical and 4 horizontal AAA batteries.
*   **Parametric Design:** Everything, including battery size (radius), wall thickness, base height, hole depth, and the number of batteries in each dimension should be easily changeable via parameters.

I'm thinking that a single OpenSCAD file should be fine for this.  I'd like to be able to specify these parameters at the top of the file and then just render the model. Can you do this for me?  I'm not using any special libraries for this and I think all of the primitives used should be part of the standard OpenSCAD library (ie `cube`, `cylinder`, `difference`, `translate`, and `for` loops).

I'd like to design a customizable miniature stone house for tabletop gaming, similar to the provided `winwall_.scad` file, but with some improvements and more modularity. I want to be able to control all of the main dimensions, window and door placement, wall texturing, roof style, and add-ons like a chimney.

Here are the specific features I'm looking for:

**Overall Structure:**
*   **Parametric Dimensions:** I need to set the overall X, Y, and Z dimensions of the main house body (length, width, height).
*   **Roof Height:** I'd like to control the roof's peak height separately. The roof should be a simple pitched roof.
*   **Wall Thickness:** The thickness of the walls should be adjustable, and not just implied by window recesses.

**Walls:**
*   **Brick Texture:** I want a customizable brick texture on the walls using a "stone" module, similar to the original file.
    *   Adjustable stone height, width, and depth.
    *   Control over how "round" the stones are (using a sphere or rounded cube for the stone shape).
    *   Adjustable randomness in the stone placement and size.
    *   Option for a flat-faced brick style vs the current "protruding" or rounded style.
*   **Base Stones:**  A separate module to control the base layer of larger, more rugged stones along the bottom of each wall.
    *   Adjustable size and randomness.
*   **Wall Modularity:** The walls should be generated individually, not with rotation. I need to be able to output a single wall for printing (like `asplate==1` in the example).

**Windows and Doors:**
*   **Placement:** I need a way to define window and door placement along each wall. It'd be great if I could set this as a list of placement types (window, door, none) with positions along the wall, rather than having it defined at a particular number.  I do not need the concept of a `WD` array.
*   **Dimensions:** Individual control over window and door height, width, and depth.
*   **Window Style:** I want some more customizable options in window style:
    *   A basic window frame and panes
    *   More elaborate window frames and sills
    *   A way to optionally add shutters
    *   Maybe circular, triangular, and arched window styles
*   **Door Style:**
    *   Simple door frame with a panel
    *   Ability to add a handle, knocker, or decorative elements
    *   Option for an arched or rounded door
*   **Recess:** Both windows and doors should be recessed into the wall. The depth of the recess should be configurable.

**Roof:**
*   **Tile Texture:** Similar to the walls, the roof should have a customizable stone or tile texture, again using a "stone" module, with:
    *   Adjustable tile size and depth.
    *   Control over rounded or flat tile style.
    *   Adjustable randomness in tile placement.
*   **Overhang:** I want independent control of the roof overhang on all sides.
*   **Roof Types:** In addition to a standard pitched roof, it would be nice to have options like:
    *   A hip roof
    *   A gambrel roof
    *   A flat roof with a parapet wall.
*   **Roof Block:** An independent module to output an individual roof block for printing.

**Chimney:**
*   **Parametric Chimney:** Separate module to create a chimney with:
    *   Adjustable X, Y, and Z dimensions
    *   Adjustable position on the roof (and I need to be able to do math to avoid collisions with the roof sides, probably).
    *   A brick/stone texture that matches the walls
    *   Optional chimney cap or design element.

**Modularity and Output:**
*   **Individual Parts:** I need to be able to output the main house body, individual walls, roof sections, and chimney as separate parts for easier printing and modification, without a need to use the "asplate" mode or the "part" parameter.
*   **Clear Parameters:** The OpenSCAD code should have clear, well-documented parameters for all of these settings.
*   **Preview:** A good view for the preview window.

**Libraries**
*   I would prefer not to use any external libraries (MCAD, BOSL, BOSL2, etc) in order to keep the code simple for my purposes.

I'm looking for a well-structured, modular OpenSCAD design that is easy to customize and extend. I'm not worried about the model being watertight, I'm fine with fixing it myself in a separate tool.

I need an OpenSCAD design for a small tray that sits underneath an electrical outlet, and also includes the outlet itself as a negative space. The basic idea is that the tray will hold some excess cabling that comes out of the outlet.

Here are the key features I need:

*   **Electrical Outlet:** The outlet should be a rectangular hole in the main body, sized to fit a standard electrical outlet. The dimensions of this outlet opening should be parameterized. Let's call the width `plug_side`, the height `plug_h`.
*   **Wall Thickness:** Around the outlet opening, there needs to be a wall. The thickness of this wall should be `plug_gap`. The depth of the wall outside the outlet is `plug_depth`.
*   **Main Tray:** The tray should have a flat, rectangular base. The width of the tray needs to encompass the wall around the outlet and can be derived from the sum of the plug width + 2 wall thicknesses. Let's call the tray width `tray_w` which should equal `plug_side + plug_gap*2`, and the length of the base `tray_len`. The tray should have a small height that is equal to the wall thickness from around the outlet.
*   **Tray Sides:** The tray should also have short sides that curve upward. These sides can be made using a triangle rotated and positioned on the back side of the tray. The height of these sides at the end should be `tray_side_bend_h`, and the width of the angled side should be `tray_side_bend_w`.
*   **Cable Slits:** The tray needs to have multiple slits cut into the back of the tray where cables can enter. Each slit should be positioned equally along the width of the tray. The depth of the slit should be `slit_depth`. The radius of each cable is `cable_r` and each slit has an opening length `slit_open_l`. The number of slits `slit_count` should be a parameter.

Essentially, the final design should have the outlet as a negative space in the main body, a tray extending out from that, and slits in the back wall of that tray. Everything should be fully parameterized so it's easy to adjust the dimensions. I'd also like the design to be in a single file.

Hey, I'm looking to create a chainmail-like pattern for 3D printing, but I want it to be configurable based on a few parameters and also be resistant to the links rotating on the build platform. I've seen some designs that use interlocking links instead of simple rings and I think that would work well, but I want to make sure I can control the overall size and spacing.

I need a design where the links are essentially flat, interlocking squares or rectangles, with a sort of "plus-sign" cutout in the middle, and that are linked together at 45-degree angles. So the individual links are all oriented in the same direction relative to the world axes, but adjacent links are rotated 45 degrees relative to one another within the plane. I would like to be able to specify the dimensions of the individual links and the overall platform size for my printer so it generates an appropriate grid.

Specifically, I'd like to be able to set:

*   `link_size`: The overall size of a single link, probably in millimeters. This would control both the x and y dimensions (it should be a square) of the main body of the link.
*   `platform_width`: The width of the printing platform.
*   `platform_depth`: The depth of the printing platform.

I'm not too worried about the thickness of the links; something reasonable for printing would be fine. And I would also want a bit of a gap between the links for movement.

For placement and duplication, I would like to use the "Belfry OpenSCAD Library". I already have a local copy of this library. It handles things like translating, rotating, and mirroring.

Could you generate the necessary OpenSCAD code for this, including the library calls? I don't want to have to rewrite the whole thing and I'm just looking to get a configurable grid generated.

[Assistant]
ChainMail.scad:
```
// Size of individual chain links.
link_size = 12; // [5:50]

platform_width = 150; // [100:500]

// Usable print platform depth, front to back.
platform_depth = 150; // [100:500]

I'm looking to create a customizable flange design using OpenSCAD. I have an existing STL file named "flange_3-9.stl" that I want to use as a base. I need to be able to adjust the length of a "finger" or tab that extends from the flange.

Specifically, I want to be able to control the scaling of the flange along the X-axis based on the finger length. If the finger length is set to 4, the flange should be scaled by 1.1 along the x-axis. If it's set to 5, it should be scaled by 1.2 along the x-axis.

Could you create an OpenSCAD file or files that implements this functionality? I'm hoping for something modular if possible. It should be easy to adjust the finger_length and have the scaling updated accordingly.

[Assistant]
test_flangeV2.scad:
```
import("flange_3-9.stl");
//finger length
finger_length=4;
if(finger_length==4){
scale([1.1,1,1]) import("flange_3-9.stl");}
if(finger_length==5){
scale([1.2,1,1]) import("flange_3-9.stl");}
```
test_flangeV3.scad:
```
//import("flange_3-9.stl");
finger_length=4;
if(finger_length==4){
 scale([1.1,1,1]) import("flange_3-9.stl");}
//if(finger_length==5){
//scale([1.2,1,1]) import("flange_3-9.stl");}

I need a customizable faceplate for a Hammond enclosure, specifically designed to house a MangOH development board. I'd like to be able to adjust the positions of the various cutouts, and ideally be able to turn some of the cutouts on and off.

The design should include cutouts for:
*   A VGA port
*   LED indicators
*   A button
*   An audio jack
*   A USB port (horizontal orientation only)
*   An RJ45 connector
*   And ideally, three SMA antenna connectors that can be enabled or disabled.

Here are some parameters that should be adjustable:

*   `Vertical_Distance`: The distance between the top of the board and the bottom outside surface of the enclosure.  (Default: 8.5, for small enclosure on bottom rung; 20 for large enclosure on 4th rung.)
*   `Component_Fit`: An offset for component holes to adjust the fit. (Default: 0.25)
*  `Plate_Fit`: An offset for the faceplate edges to adjust the fit. (Default: 0.25)
*   `Face_Plate_Height`: The height of the face plate inside surface (Default: 31 for small, 53.3 for large).
*   `Face_Plate_Width`: The width of the face plate inside surface (Minimum: 104).
*   `VGA_Horizontal_Offset`: Horizontal offset of the VGA cutout.
*  `VGA_Vertical_Offset`: Vertical offset of the VGA cutout.
*   `LED_Horizontal_Offset`: Horizontal offset of the LED cutout.
*   `LED_Vertical_Offset`: Vertical offset of the LED cutout.
*   `Button_Horizontal_Offset`: Horizontal offset of the button cutout.
*   `Button_Vertical_Offset`: Vertical offset of the button cutout.
*   `Audio_Horizontal_Offset`: Horizontal offset of the audio jack cutout.
*   `Audio_Vertical_Offset`: Vertical offset of the audio jack cutout.
*   `RJ45_Horizontal_Offset`: Horizontal offset of the RJ45 cutout.
*   `RJ45_Vertical_Offset`: Vertical offset of the RJ45 cutout.
*   `USB_Horizontal_Offset`: Horizontal offset of the USB cutout.
*  `USB_Vertical_Offset`: Vertical offset of the USB cutout.
*   `Lid_Fill`: Boolean to fill the gap between faceplate and lid for flat lids (true/false).
*   `Antenna_1_Horizontal_Offset`, `Antenna_1_Vertical_Offset`:  Offsets for SMA antenna 1, set to "false" to disable.
*  `Antenna_2_Horizontal_Offset`, `Antenna_2_Vertical_Offset`: Offsets for SMA antenna 2, set to "false" to disable.
*  `Antenna_3_Horizontal_Offset`, `Antenna_3_Vertical_Offset`: Offsets for SMA antenna 3, set to "false" to disable.

Internally, the faceplate has a wall thickness of 1.5, an inside z height of 7, and an outside z height of 9.  The SMA connectors should have a diameter of 7, with a gap of 7 between them, starting 18.5mm from the left edge and 13mm from the front edge, relative to the inside dimensions.

The main body should include fillets (rounded edges) both internally and externally using the specified `Wall` thickness for a radius offset. The screw holes should be countersunk and have a diameter of 3 for the main hole and 6 for the countersink, and a countersink depth of 2.2.

The OpenSCAD file should be parametric so that I can adjust all of these settings. I don't think there's any need for external libraries like MCAD or BOSL.

Hi, I need a customizable faceplate for a Hammond enclosure, specifically designed to work with a MangOH development board. I'd like to be able to select different types of connectors for up to three slots, like Micro-D, SMA, RJ45, single USB, or double USB, or even have no component at all for a slot. I also need to be able to adjust the vertical distance between the top of the board and the outside surface of the enclosure, and have some control over component fit by adjusting hole sizes. Also, it's really important that I can change the plate dimensions to adjust for different size enclosures, including the inside height and width.

I'd also like to be able to adjust horizontal and vertical offsets for the power connector, the three slots, the USB port, and 3 LEDs, so they can be positioned correctly. I have two different sizes of Hammond enclosures, so I'm going to need to make sure that the plate works with both. I'd also like a parameter that fills the gap between the faceplate and the enclosure lid, especially if I use a flat lid like a laser cut piece of acrylic.

The design should include screw holes for mounting. I would also like to be able to control the fillet radius on both the inside and outside edges of the plate.

Could you generate an OpenSCAD file for this? I don't need any external libraries for this project, I prefer using all built-in functions.

Hey, I'm looking to design a parameterized wheel for a small gearmotor, the kind you see on eBay. I'd like it to be customizable so I can adjust the size, spokes, etc. I've got a working design here (babybot-wheel2.scad) but I'd really like a version where all the parameters are easily changed.

Here's a breakdown of the features I need:

*   **Wheel Diameter:** This should be adjustable, probably between 10mm and 150mm (parameter: `wheel_dia`).
*   **Rim Thickness:** I need to be able to set the thickness of the outer rim (parameter: `rim_thickness`).
*   **Wheel Width:**  The width of the rim itself needs to be adjustable (parameter: `wheel_width`).
*   **Number of Spokes:**  The wheel needs to have spokes, and the number should be adjustable, maybe from 2 to 16 (parameter: `num_spokes`).
*   **Spoke Thickness:** The thickness of each spoke should be adjustable (parameter: `spoke_thickness`).
*   **Shaft Bore:** I'll need a center bore that fits a specific shaft. The shaft has a diameter and also flats, like a "D" profile. This needs to be a parametric opening:
    *   **Shaft Diameter:** The diameter of the round part of the shaft (parameter: `shaft_dia`).
    *   **Shaft Flats Diameter:** The width between the flats of the shaft (parameter: `shaft_flats_dia`).
    *   **Shaft Tolerance:**  A small tolerance value to make sure the wheel fits on the shaft (parameter: `shaft_tolerance`).
*   **Hub Width:** The width of the center hub that receives the shaft (parameter: `hub_width`).
*   **Hub Thickness:** The thickness of the hub around the shaft bore (parameter: `hub_thickness`).

I'd also like to use a `cube2` module that allows for rounded corners and centers the cube based on a combination of string alignment parameters, like "LCL," "CCR," and "RLL".  It should work with `radius` and `xy_radius`. I also need a `tube` module that creates a cylinder with a hole and a `double_flat_circle` module which creates a circle with a D shaped hole in the center.

I think I want these as named modules that are called from a main `wheel()` module to create the actual wheel.  Could you create the `cube2`, `tube`, and `double_flat_circle` modules, as well as the `wheel` module, all in one .scad file? I will be handling the use statement for any libraries.

I'd like to create a toy that changes its shape as you twist it. It'll be made up of several identical, stacked pieces, each of which can rotate relative to the one below. I'd like a parametric OpenSCAD design for this, where I can control various dimensions and the number of pieces.

Here's a breakdown of what I envision:

Each individual piece, let's call it a "spinner," consists of a central connector with two balls on opposite ends. The balls should be spherical, but the 'height' is adjustable such that they appear more like ovals.  The central connector is a cylinder with a bar running through it.  This bar extends out to the balls. The central connector also has a cylindrical cutout for a dowel in the middle. At the top and bottom of the cylinder section, there should be an indented part that allows for a specific amount of rotation in each direction. That is, the top of each connector should have two indents allowing for 8 degrees rotation in one direction, and 40 in the other direction, or whatever I specify.

The overall structure will be a stack of these spinners, with the top and bottom having special caps. The top cap should have a protrusion that fits into the indent of the top spinner and the bottom cap should have an indent for the bottom spinner, and dowel cutout like all the other spinners.

I'd like to be able to control the following parameters:

*   `spinners`: The number of spinner pieces in the stack.
*   `rotatePreview`:  An angle which specifies how much each spinner rotates in the stack
*   `startDist`: The initial distance from the center to the balls on the first spinner.
*   `distStep`:  How much the distance from center to balls increases for each subsequent spinner.
*   `ballWidth`: The width of the spherical balls.
*   `ballHeight`: The height of the balls.
*   `connectorWidth`: The width of the central connector cylinder.
*   `indent`: The depth of the indent on the top and bottom of the connector.
*   `extrude`: The height of the protrusion on the bottom of the connector.
*   `margin`: Extra height between balls to keep a gap

I'd also like to be able to change the rotation angles for the indents in the connectors; you can assume two rotation values for the indent, like 8 and 40 in the example file. Oh, and I would like the middle dowel cutout to have a specific diameter and a length that's more than necessary (so the user can just adjust).

Could you create an OpenSCAD design that does all of this? I think it could probably be done in a single file.

Hey there, I'm looking to create a sort of modular castle design in OpenSCAD. The basic idea is to have a central tower-like structure with repeating details that iterate upwards.

Specifically, the base unit should start with a hexagonal cylinder and then have three 'supports' or ribs around the outside that each combine two smaller cylinders. These cylinders should be placed parallel to the main axis of the larger hexagonal cylinder.  Then, all of these shapes are used as a cut away from another slightly smaller hexagonal cylinder of the same height to form a basic structure.

From there, I want this base module to be repeated and scaled smaller on top of the base, around the edges. Ideally, this should form a ring of similar structures. This process will repeat as many times as needed, scaled down each time. In each iteration, it will have 6 copies that are placed at the top and around the original tower, but in the scale of 2/6 for each horizontal axis and 1/2 along the vertical.

On each level except the last, it should also have an additional decorative intersecting structure, kind of a double-cone type shape that is made by a hull between two spheres. This intersects with a basic structure made from two rotated cylinders that are each placed on their sides with an intersecting region. It's a bit complex and the current code uses `union`s, `intersection`s, and `hull`s together.

I'd like to control the overall size with a single parameter, maybe `base_size` or `taille` as it's called in the code, and control the number of iterations/levels via another parameter, maybe `iterations` or `IterMax`.

Could you generate an OpenSCAD file for this? I don't have any specific library requirements. Thanks!

Hi, I'm looking to design a customizable button for 3D printing, optimized for conductive filament, and I'd like your help generating the OpenSCAD files. It should have a few key features:

First, the button should have a main body with a rounded edge and a flat top. I need to be able to control the straight part and rounded part of the button independently in terms of dimensions. Let's call these `BUTTON_STRAIGHT` and `BUTTON_ROUNDED`, both in millimeters.

Second, there should be an inset area in the center of the button that will serve as a conductive badge. This badge should be slightly recessed into the button and also have a rounded edge, let's call this `BADGE_ROUNDED`. The badge should be a separate part, and the two parts of the button and the badge should fit together nicely.

Third, I'd like to be able to put a letter on both the main button and the conductive badge.  The letter should be configurable with the `LETTER` variable, and it needs to be centered. On the main button, it should be a recessed engraving, and on the conductive badge it should be raised.

Fourth, I need to control the resolution of the curves and circles with a `RESOLUTION` parameter, as well as a `TOLERANCE_DIAMETER`, and a `LAYER_HEIGHT`, all in millimeters.

I'd also like to have a `VIEW` parameter which lets me display the conductive badge on its own, the button without a badge, the letter itself, a combined view of button and letter or a combined view of all parts. I'd like to be able to specify colors with a `COLOR_SCHEME` option. Let's have some options for both conductive and non-conductive material, such as "Khaki/Grey", "Wood/Grey" and "Silver/Black".

So to summarize, I need the following parameters:

*   `BUTTON_STRAIGHT` (mm): Length of the flat edge of the button.
*   `BUTTON_ROUNDED` (mm): Radius of the rounded edge of the button.
*   `BADGE_ROUNDED` (mm): Radius of the rounded edge of the conductive badge.
*   `LETTER`: The text (single character) to display on the button and badge.
*   `RESOLUTION`: The resolution used for curves and circles
*   `TOLERANCE_DIAMETER` (mm): The tolerance for the fit of the badge within the button.
*    `LAYER_HEIGHT` (mm) The layer height used for printing.
*   `VIEW`:  Integer to control the view.
*   `COLOR_SCHEME`: Integer to control the color scheme.

I'm thinking this could be built using standard OpenSCAD primitives and I don't think I need any external libraries for this design. Can you please generate the necessary SCAD files?

I'd like to design a model of a sphere held captive inside a cube, and I need your help generating the OpenSCAD code. The cube should have circular holes on each face that allow the sphere to be inserted, but are too small for the sphere to escape once it's inside.

Specifically, the design needs to be parametric. I want to be able to control:

*   The overall width of the cube, which should also dictate the diameter of the sphere, such that the sphere touches the inside faces of the cube.
*   The thickness of the cube's walls. This will also control the size of the circular holes, as the holes are simply the cube's width minus the thickness.

So, I'll specify the cube width and wall thickness, and everything else should derive from those values. Can you provide the necessary OpenSCAD file(s)? It would also be great if you could add comments to explain how the code works. Thanks!

[Assistant]
Captive_Sphere.scad:
```
// A simple model of a sphere held captive in a cube.
$fn = 72 * 1; // Make the sphere and circles fairly smooth

// The outer dimension in millimeters of the cube and the diameter of the sphere
width = 25; // [10:150]

// The thickness of the cube walls
thickness = 3; // [1:0.5:10]

holedia = width - thickness; // size of the circular holes on the cube's faces

difference(){
    cube(size = width, center=true); // the outer cube
    cube(size = width - thickness, center = true); // subtract a cube inside it
    cylinder(r = holedia / 2, h = width + 2, center = true); // circular holes on the top and bottom
    rotate([90, 0, 0]) cylinder(r = holedia / 2, h = width + 2, center = true); // and on the Y axis
    rotate([0, 90, 0]) cylinder(r = holedia / 2, h = width + 2, center = true); // and on the X axis

}
sphere(r = width / 2, center = true); // place a sphere in the center of the box

Hey, I'm looking for an OpenSCAD design for a sink drain strainer, and I'd like it to be customizable with a few options. I'm working from an existing design, but it's a bit rough and I'd like to start over fresh.

Here's what I need:

*   **Basic Basket Shape:** The main part should be a sort of shallow, inverted dome with a rim. It should have a bunch of holes or slots around the sides for water to drain, but small enough to catch hair and debris. I'd like to be able to adjust the overall diameter of this basket.

*   **Center Post Options:** I want to have a few options for the center of the strainer, and be able to choose between them. These will all attach to the top center of the basket, so that I can lift the strainer out of the drain. The options are:
    *   **Simple Post:** A basic straight post.
    *   **Hourglass Post:** A post with a slightly tapered top and bottom.
    *   **Ball Handle:** A simple sphere handle on a small post.
    *   **Hole:** Just a simple hole through the center if I don't want a handle.
    *   **Fluted:** A sort of hourglass shape

*   **Helper Disk:** I want a thin disk on the bottom edge, like a brim for 3D printing, to help it stick to the build plate. This should be optional.

*   **Parametric:** The key thing is that I'd like this to be parametric and customizable, specifically, I want to control the overall diameter of the strainer. The rest of the dimensions can scale proportionally to the diameter.

I'm using OpenSCAD, and I'm fine if you need to include some helper libraries. I also want a `build_plate` helper module, so that the first thing is to draw a build plate of size zero. I think that's about it.  Thanks!
