Hey, I'm looking to create a customizable enclosure using OpenSCAD and I need some help building the code for it. I want to be able to specify the width, height, and depth of the enclosure, as well as the thickness of the walls and the radius of the corner fillets. It should be a simple rectangular box with a separate lid. The lid should sit on top of the enclosure, and should have the same width and height as the main enclosure body, plus a bit of an offset to make it easily visible in the 3d view (like 10mm), and the same wall thickness.

I'd like the code to use a modular approach, where there's a module to generate the basic rounded-corner rectangular solid (which I can reuse), a module to create the enclosure body using this base shape, and a separate module to generate the lid.

Could you generate the required `.scad` file for me, please? I'm not using any specific libraries, just the standard OpenSCAD primitives.

I'm looking to create a customizable clip, and I've got some basic dimensions in mind, but I want to make them easily adjustable. I envision a clip profile with a flat base, a vertical section that then angles inwards, and a bit of a lip at the top.

Here's what I need:

*   **Base Width:** This should be a parameter for the overall width of the clip's base.
*   **Base Thickness:** The thickness of the base section that sits flat, before the vertical wall starts.
*   **Wall Height:** The height of the vertical portion of the clip.
*   **Inward Slope:** The angle at which the clip angles in, starting from the top of the wall. It would be great if this parameter was defined in terms of the vertical distance it covers as it comes in.
*   **Lip Height:** The vertical distance of the lip at the top of the slope.
*   **Clip Depth (Extrusion Length):** The length of the clip after it's been extruded.

So essentially, the clip profile starts at \[0,0], extends to \[Base Width, 0]. It goes up by Base Thickness to the start of the wall, goes up again by Wall Height. Then the slope happens, based on the Inward Slope parameter. The lip then goes up and back to the vertical, and that is the end of the profile.

Could you create an OpenSCAD file or a couple of them that uses these parameters to define the clip, and extrudes it to the Clip Depth?
I would like to see it utilize libraries like BOSL2 if that's relevant here, and ideally keep things modular with functions. Thanks!

[Assistant]
Clip_Customizable.scad:
```
height = 5;
slope = 3.5;
clipWidth = 10;

trueHeight = height + 1;
draftHeight = trueHeight - slope;

linear_extrude(height = clipWidth) {
    polygon(points = [  [0,0],
                        [24,0],
                        [24,2],
                        [4,2],
                        [4,2 + trueHeight], //2+6=8
                        [25,2 + draftHeight],
                        [25,2 + draftHeight + 2.5],
                        [0,2 + trueHeight + slope ]
                       ]);

}

Alright, I'm looking to design a customizable router/switch holder that'll be compatible with those media cabinets, using OpenSCAD. I've got some specific needs in mind, and I think it would be best broken down into a few modules that can then be combined.

The base of the design is a rectangular "shelf," which I think of as a 'Top' section, mirrored across the Y axis. On either side, there will be a vertical 'Side' wall that helps support the router/switch. Then, underneath the shelf, I need a supporting structure running the length, lets call it 'Support', also mirrored. Finally, I need some studs, which can also be mirrored to allow for mounting the router/switch itself.

Here are the key parameters I need to be able to adjust:

**Overall Dimensions:**

*   `TopWidth`: The total width of the top "shelf" part.
*   `TopDepth`: The depth of the top shelf.
*   `TopHeight`: The height of the top shelf. This will affect the height of the side walls.
*   `WallThickness`: The thickness of both the Top and Side pieces.

**Support Structure:**

*   `SupportWidth`: The width of the supporting structure under the shelf.
*   `SupportDepth`: This should match the `TopDepth`.
*   `SupportHeight`: The height/thickness of the support structure.
*  `SupportHoleRadius`: radius of the mounting holes on the supports.
*  `SupportX`: Distance apart of the support mounting holes.
*  `SupportY`: Distance apart on each hole on the Y axis.

**Studs:**

*   `StudX`: The X-coordinate of the stud, relative to the center (and mirrored).
*   `StudY`: The Y-coordinate of the stud.
*   `StudNeckHeight`: The height of the neck of the stud.
*   `StudNeckRadius`: The radius of the neck of the stud.
*   `StudCapHeight`: The height of the head/cap of the stud.
*   `StudCapRadius`: The radius of the head/cap of the stud.

I want to ensure that the 'Support' structure will have holes for mounting it to the cabinet. They'll be spaced 12mm apart on center, with a hole size of 6mm and 153mm apart on center.  The holes need to be in the 'Support' module. Also, the stud positions need to be independently adjustable from these mounting points. The `StudX` and `StudY` values should dictate their position.

I'd like the design to be symmetrical across the Y axis, where the studs and all base pieces are mirrored using a single mirror operation at the end. This will be useful if I want to make it bigger later.

Could you generate the OpenSCAD file(s) for this? I don't have any specific library requirements, so standard OpenSCAD functions should be fine for now. Thanks!

Okay, so I've got this idea for a customizable Braille alphabet generator in OpenSCAD. I'm not sure how to write it myself though, so I'd like you to give it a shot. I've kind of got a proof of concept, and I'll attach the code for that.

Basically, I want to be able to input text, and it should output a series of Braille characters.  Each Braille character is made up of raised dots in a 2x3 grid, so that's key. I need to control the following parameters:

*   **Dot Dimensions:** The diameter and height of each individual Braille dot.
*   **Dot Spacing:** The gap between dots within a single Braille character in both the X and Y directions.
*   **Character Spacing:** The gap between each complete Braille character in both X and Y directions.
*   **Board Type:** The design should have an option for no base board, or for a base board with connectors on the left, right, or both sides to join multiple character blocks together. This will involve adding connector cylinders extending out from the base.
*   **Board Dimensions:** The board should have a thickness, a corner radius, and the diameter and offset for the connection cylinders.
*   **Corner Detail:** Control the number of facets used to create the board corners.

The main input, of course, is the text string. This should be converted into the corresponding Braille characters. I'd expect you'd have some kind of lookup table for that.

I'm thinking it would also be really useful if the generated module would allow for individual dots to be controlled directly, using an array or something. That is, if I could put in a list of booleans representing the state of each dot, I would be able to generate any custom character I needed.

I think that covers all of my requirements, but let me know if anything is unclear.

Alright, so I'm trying to design a parametric cable holder for attaching to the edge of a table, and I'd like your help generating the OpenSCAD code. I want it to be able to hold a cable of a specified diameter, and be able to clamp onto a table of a specified thickness. The holder should consist of a rotating inner barrel that actually grips the cable, an outer body that the barrel sits inside of, and tabs that hold the whole assembly onto the table.

Here are the specific parameters I need:

**Basic:**
*   `cable_diameter`: The diameter of the cable to be held, in mm.
*   `table_thickness`: The thickness of the table edge to clamp onto, in mm.
*   `tolerance`: A general tolerance value in mm to control gaps between moving parts.

**Table Tabs:**
*   `tab_length`: The length of the tabs that grip the table edge, in mm.
*   `tab_thickness`: The thickness of the tabs, in mm.

**Table Grip:**
*   `grip_height`: The height of the triangular grip feature on the lower tab, in mm.
*   `grip_width`: The base width of the triangular grip feature, in mm.

**Thumbwheels:**
*   `thumbwheel_height`: The height of the end thumbwheel features on the barrel, in mm.

**Count:**
* `count`: The number of holders in a chain, where each holder is linked to the previous one.

**Tab control:**
* `upper_tab`: A boolean value that turns the upper table tab on or off.
* `lower_tab`: A boolean value that turns the lower table tab on or off.

**Advanced:**
* `show_seperate`: A boolean value, if "yes" then the inner barrel is generated as a separate object, for easier printing.
*   `retainer_factor`: A value that affects the thickness and lift of the inner barrel's retaining section. You might have to play with this parameter to get a good fit, suggest using integer values from 3 to 10, but it's not required.
*   `plane_cut_factor`: A value between 0 and 2, that effects the depth of a plane cut feature added for ease of printing.
*   `$fn`: The number of faces for cylindrical objects.

**Advanced Neck:**
*   `neck_thickness`: The thickness of the inner rotating cuff (the "neck") of the barrel, in mm.

**Advanced Holder:**
*   `holder_thickness`: The overall thickness of the outer holder in mm.

I'd like the design to be parametric, so that I can adjust these values and the holder will automatically update. I want to use the standard OpenSCAD library; nothing extra is needed. Also, could you provide comments in the code explaining each section and parameters as well? I think I've covered everything, let me know if you need more information!

I'd like to create a puzzle generator in OpenSCAD. The basic idea is to have rectangular puzzle pieces with interlocking tabs and slots on all sides. I'm going to need to be able to control the number of pieces in the x and y directions, the side length of the individual pieces, the overall height/thickness of the puzzle, and a small spacing between the pieces to allow for manufacturing tolerances.

The puzzle pieces should have a square base shape. For each piece, there should be two half-circle indentations on the left and top sides of the piece, and corresponding protruding half-circles on the right and bottom sides. These protruding tabs and indentations should be positioned along the vertical and horizontal centerlines of each side. These pieces should then fit together snugly when tiled to create a final assembled puzzle. The overall puzzle should be a rectangle with the width equal to the number of pieces multiplied by the side length (plus a small amount) and the height calculated similarly.

I'd like to control these parameters:
- `piece_side_length`: The length of the side of a single puzzle piece.
- `piece_height`: The overall thickness of the puzzle.
- `xs`: The number of pieces in the x direction.
- `ys`: The number of pieces in the y direction.
- `spacing`: A small space between the pieces to avoid overlapping while printing.

Could you write the necessary OpenSCAD code? I don't need any external libraries. I'm expecting a couple of modules, `puzzle_piece` and `puzzle`, and a main body to extrude the final result. Thanks!

I need some help designing an OpenSCAD file for a clay nozzle guide.

The guide should have a cylindrical base with a configurable diameter and height. On top of this base, there will be a shoulder section, which is just another cylinder with a fixed diameter equal to the internal diameter of the rocket motor. The height of this shoulder is also configurable.

Above the shoulder, the nozzle itself begins. This is a conical section that tapers down to a point, creating the nozzle shape. The angle of this taper should be adjustable.

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

*   **ID:** Internal diameter of the rocket motor (in mm). This will also be the diameter of the shoulder section.
*   **ANGLE:** The angle of the nozzle taper (in degrees).
*   **SHOULDER:** The height of the shoulder section (in mm).
*   **BASE\_DIAMETER:** The diameter of the base cylinder (in mm).
*   **BASE\_HEIGHT:** The height of the base cylinder (in mm).

Essentially, I want to be able to plug in these values and get a 3D model of the nozzle guide that I can use to form a clay nozzle. The guide should accurately reflect the desired internal geometry of the nozzle.

Could you help me create a parametric OpenSCAD file that does this? I don't need any libraries for this.

I need a parametric stand designed in OpenSCAD, please. It should be a simple frame with four corner supports, like legs, and a flat top. The dimensions need to be customizable so I can fit various trays underneath.

Specifically:

*   I need to be able to specify the inside width, length, and height of the space under the stand.
*   The stand should have four vertical legs/pillars at the corners.
*   The legs/pillars need to have a defined width, and should be hollow to reduce printing time. The wall thickness for the pillars should also be configurable.
*   The top of the stand should be a flat plate, and the thickness of this plate should also be customizable.
*   The external dimensions of the stand should be automatically calculated based on the internal dimensions and the leg width.

For example, if I set an inside width of 150mm, and the legs are 10mm wide, the overall width of the top plate should be 170mm.

I'm not looking for anything fancy in terms of aesthetics, just a functional, printable frame. I'm not using any specific libraries, just core OpenSCAD.

Hi, I'd like to create a customizable stress toy made of connected cubes, kind of like a snake. I'd like the design to be parametric in OpenSCAD so I can adjust the size of the cubes and the holes for the elastic cord.

Specifically, I need two types of cubes: "middle" cubes and "end" cubes. The middle cubes will have two holes running through them in different directions to allow the elastic cord to connect them in a chain. The end cubes will have the same kind of hole but also an additional larger hole on the top for knotting the elastic cord.

I'd like to be able to control:

*   The overall size of the cube (all sides equal)
*   The diameter of the smaller hole for the elastic cord to pass through
*   The diameter of the larger hole in the end cubes for the knot
*   Whether to render just middle cubes, just end cubes, or both together for preview.

I plan to use 2mm elastic cord and currently have a hole size of 2.4 mm for that. The top hole in the end cube is currently 2.4 times the cord hole and the actual hole for the cord is 0.6mm larger to make it easier to thread.

Could you please generate the necessary OpenSCAD code for me? I'm not using any specific libraries, so you don't have to worry about that. Thanks.

I'm looking for a parametric design for a crush tube, something I can use to create a defined gap between two bolted parts while providing some support. I have a basic design in mind, sort of like a tube with some internal bracing.

Specifically, I need a cylindrical tube with the following features and parameters:

*   **Tube Height:** A variable defining the overall height of the tube.
*   **Center Hole Diameter:** A variable for the diameter of the hole running through the center.
*   **Inner Ring Width:** A variable for the width of the inner-most solid ring surrounding the center hole.
*   **Outer Diameter:** A variable for the outer diameter of the entire tube.
*   **Outer Ring Width:** A variable for the width of the solid outer ring at the perimeter.
*   **Spoke Quantity:** A variable for the number of spokes connecting the inner and outer ring.
*   **Spoke Width:** A variable defining the thickness of each spoke.
*   **Additional Rings:** A variable for the number of additional concentric rings between the inner ring and the outer ring. These should be evenly spaced.
*   **Additional Ring Width:** A variable for the width of each additional ring.

I'd like all of these to be customizable parameters in the OpenSCAD file. The design should be constructed from the ground up in SCAD, so please don't try to use any external library files.

The design should include:
1. A central hole through the cylinder.
2. An inner ring around the central hole.
3. An outer ring, forming the outer edge of the tube.
4. Spokes connecting the inner ring and outer ring. These spokes should be evenly distributed.
5. An optional number of additional concentric rings evenly spaced between the inner and outer ring.

Hey, I'm trying to design a mold for a headphone repair, specifically for the Y-split where the two earbud wires meet the main cable. I've seen some similar designs, but I want something parametric so I can adjust it to different headphone sizes. I'd really like to be able to control a bunch of things, like:

*   The diameter of the wires going into the mold (both earbud wires and the main cable).
*   The outer diameter of the sheath around those wires.
*   The length of the sheaths on both the earbud and the main cable sides.
*   Some kind of texture on the outer surface of the sheaths, just for grip and aesthetics. I'm thinking maybe a ribbed texture?
*   The diameter of the central joint where all the wires come together.
*   The angle between the earbud wires coming out of the mold.
*   Also, I'd like some bolt holes in the mold so I can clamp the mold together easily.

Ultimately, I need a negative mold to create a positive cast of the part using Sugru, so I'll need two mirror-image halves to clamp together. The bolt holes should align on these. I'm thinking it should be a two-part mold with a flat joining surface for easy clamping. I'm trying to avoid undercuts too, so that the suguru form can be easily removed once it's cured.

Could you help me create an OpenSCAD file (or files if it makes sense) that lets me do this? I'm familiar with basic OpenSCAD, so a modular approach would be great, and I would like to avoid relying on libraries other than the standard built-in OpenSCAD modules, to keep things simple.

Hey, I'm working on a coil winder and need a parametric model for the coil form. I have a basic model, but I think an AI could do a much better job and make it more flexible.

Essentially, I need a spool-shaped object, with these key features:

*   **Central Cylinder (Corpus):** This is the main part where the wire will be wound. It should have a customizable radius (`r_corpus`) and height (`h_corpus`).

*   **Border Flanges:** At the top and bottom of the corpus, there need to be flanges to contain the wound wire. Each flange should have a radius (`r_border`) larger than `r_corpus`, and a height (`h_border`). These should both be the same size at the top and bottom.

*   **Grip/Chuck Area:** Below the bottom flange, I need a smaller cylindrical section for gripping in a chuck of my winder. This should have a specific height (`h_grip`). I don't think the diameter is important here because I'm not using it to wind on, but if there's a standard approach or a good way to think about that, I'd love to hear it.

*   **Central Hole:** The part should have a central hole all the way through, with a customizable radius (`r_hole`).

*   **Optional Peg Hole:** I want to have the option to include a small hole on the side, near the bottom, which I could use for starting the wind. This should be optional, so if it's off, it shouldn't show up, if its turned on I need it to have a radius (`r_peg`) and to be at a specific distance from the center, `r_corpus` + `peg_offset`.

I'd like all of these dimensions to be configurable with variables in the OpenSCAD code. The peg hole would be optional, perhaps using a boolean parameter.

I'm hoping you could design the OpenSCAD code that does all of this? Let me know if you need more information from me. I would prefer if you included the following libraries to help make sure the code is robust: `BOSL`, and `BOSL2`.

I'd like to design a kitchen roll holder that can clip onto a shelf or board. It should have two identical hook-like pieces that mount onto the board, with arms extending to hold the roll.

Here are the key parameters I need to be able to control:

*   **`board_thickness`**:  This will determine the inner height of the clamp that grips the board.
*   **`hook_width`**: This controls the width of the hook itself.
*   **`roll_holder_length`**: The length of the arm that will hold the roll.
*   **`roll_holder_radius`**: The radius of the cylinder that will hold the kitchen roll. This should be a cylinder.
*   **`clamp_extension_length`**: How far back the part of the clip goes before the board mounting interface starts.
*   **`clamp_extension_depth`**: How far the clamp juts out from the back before curving to start grabbing the board.

Each hook should have:

1.  A flat, rectangular base that sits flush against the underside of the shelf/board and which goes back by `clamp_extension_length` and which has height `hook_width`.
2.  A short rectangular extension jutting out from the base that extends to a height of `board_thickness` and extends back by `clamp_extension_depth`.
3. A slanted portion that angles into the extension from the board side, creating the clamping action. This should be at least 2 degrees, probably more for good grip.
4. An arm that extends perpendicularly from the base (the side facing away from the board).  This arm should be a cylinder of radius `roll_holder_radius` and length `roll_holder_length`, positioned to hold the roll. The roll holder cylinder should have a flat area on the top (where the roll is placed), so there should be a cut going through the cylinder to make it D-shaped with the flat surface at the top (or slightly above the center, to make it easy to place the roll)

The two hooks should be mirror images of each other, and should be designed so that the roll holder arms are aligned along the same axis when attached to a board.

I need this in OpenSCAD. I would like to ensure we're using BOSL2 for any convenience functions, since that's my preferred library.

Okay, so I've got this weird little project and I need some help designing a 2.5" HDD tray for a Chenbro SK51102 enclosure, since I can't find any to buy. I've got a starting point in an OpenSCAD file (attached) that I was using to think through the general shape but it's not great.

Basically, it needs to fit into the hot-swap slot of the Chenbro SK51102 and securely hold a standard 2.5" SSD. The tray needs to have a lip/edge that the enclosure's retention mechanism can grab onto, and it needs to be robust enough that it won't break easily during normal use.

Here’s what I’m thinking, and please let me know if this sounds like the right approach:

**General Shape:** The tray should have a base that the SSD will sit on, and the base should then extend back to form the arm that goes into the slot, and then a head that is the grab point. I think the basic shape I made with OpenSCAD gets the general gist, even though it's a mess of translated cubes.  The head, where the lip grab should be, should be thicker, but the rest should be more streamlined and simple. The SSD will be placed on top of the base, and the arm will slide into the slot.

**Dimensions (and parameters):**

*   **Overall Depth (totalDepth):**  The distance from the front edge of the tray to the back edge.  This needs to be variable but I think something around 123mm will work for my case.
*   **Overall Width (totalWidth):** The width of the tray, something like 75.6mm maybe? This also needs to be parametric.
*   **Overall Height (totalHeight):** How thick the base is - This will be around 10mm
*   **Arm Width (armWidth):** The width of the arm, maybe 2.9mm, which should be a bit less than the body.
*   **Arm Length (armLength):** The length of the arm section, somewhere around 112mm, or more specifically how far back the arm goes.
*   **Arm Length Inner (armLengthInner):** The length of the arm section that goes into the slot, maybe around 101.4.
*   **Arm Height (armHeight):**  Height of the arm section itself, should be 8.9 or a bit more.
*   **Head Total Depth (headTotalDepth):** The depth of the head section, at least 22.7
*   **Head Metal Depth (headMetalDepth):** The thickness where the metal enclosure grabs the tray, should be 11mm or so.
*   **Offset Height (offsetHeight):** a small offset so the tray isn't flush with the enclosure surface, maybe 0.3mm
*   **Slit Height (slitHeight):** height of the slits, maybe around 6mm.
*   **Slit With (slitWith):** width of the slits, maybe 3mm
*    **Slit Distance (slitDistance):** distance between slits, should be 2mm.
*   **Screwhole Diameter (screwholeDiameter):**  The diameter of the screw holes, like 3.3mm.
*   **Screwhole Distance to End (screwholeDistanceToEnd):** Distance from the end to the first screwhole, maybe 14.3mm.
*   **Screwhole Distance (screwholeDistance):** Distance between screw holes should be about 76.5mm.
*    **Screwhole Height (screwholeHeight):** Height of the screw hole center, 3.3mm maybe?
* **Text:** A bit of text to label the tray.
* **Text Size:** The size of the text.

**Specific Features:**
*   **Screw Holes:** There should be screw holes for attaching a 2.5" SSD, using standard screw hole spacing (70mm, I believe, though I've measured it for my own dimensions)
*   **Retention Lip:** The head part needs to have a pronounced lip or edge that the hot-swap mechanism can grab. The original design attempts this, but it's a bit clunky.
*   **Slits:** It'd be good to have some slits on the sides of the base to allow air flow. This should be adjustable in number and size. The original attempt at this was also clunky.
*   **Mounting:** The tray needs to sit flush within the enclosure so there should be some kind of offset to prevent the tray from scraping.

**Output:**
I'd like a parametric OpenSCAD file, or maybe a few files, that can be modified. It would be great if the screw holes, slits, and text could be enabled/disabled or modified parametrically, and also if dimensions could be changed via a master parameters file. It would also be great to get a few example renders, using different parameters to see how it looks.

I think this covers everything. Do you have any questions?

Hey there, I need a design for a PCB holder for transferring traces from paper. It's basically a two-part system: a base that holds the PCB, and a sleeve that fits over the base to apply pressure.

I'm imagining the base as a simple rectangular block with a recessed area to seat the PCB. The sleeve would be a rectangular frame that fits snugly over the base and PCB, holding everything in place. I want to be able to adjust the dimensions of these parts, so it needs to be parametric.

Here's a breakdown of the parameters I need control over:

*   **`width`**: The width of the PCB.
*   **`length`**: The length of the PCB.
*   **`height`**: The height of the sleeve, how much it extends over the base.
*   **`inset`**: The depth of the recessed area in the base, the amount the PCB will sit down into the base
*   **`border`**: The width of the border around the PCB on both the base and the sleeve.
*   **`base`**: The overall height of the base block.
*   **`sleeve`**: The wall thickness of the sleeve

I'd like the design to generate two distinct parts: one representing the base and another representing the sleeve. I'd like to be able to select which part to generate using a `part` variable that can be set to `"holder"` or `"sleeve"`.

Could you please generate the OpenSCAD code for this? I'm not sure if this is relevant but I'm not using any external libraries, just standard OpenSCAD primitives.

inset = 0.5; //[0.1:0.1:5]
border = 5; //[1:0.5:10]
base = 5; //[1:0.1:10]
sleeve = 5; //[1:0.1:10]

if (part == "holder") {
 translate([0, 0, (base) / 2])

   cube([width + (border * 2), length + (border * 2), base],  true);
   translate([0, 0, (base - inset + 0.001) / 2])

Hey, I'm looking to create a parametric OpenSCAD design for a linear bearing, similar to the Igus Drylin RJ4JP-01-08. I want to be able to customize the inner and outer diameter, length, wall thickness, and the number of teeth on the inside. It should also allow for the option of including a mounting block, and if that's included, the number of mounting holes (0, 2, 4, or 6), the hole diameter, the nut size for retaining the nut on the mounting holes, and the depth of the nut cutout.

So, to recap, I need parameters for:

*   `Inside_Diameter`
*   `Outside_Diameter`
*   `Length`
*   `Wall_Thickness`
*   `Number_of_teeth`
*   `Block` (yes/no boolean)
*   `How_Many_Mounting_Holes` (0, 2, 4, 6)
*   `Mounting_Holes_Diameter`
*   `Nut_size`
*   `Nut_Depth`

I need the output to be a single .scad file, or multiple .scad files if it makes sense from a modular perspective. I'm not using any libraries that I'm aware of, so I don't need anything to be imported.

I need an OpenSCAD design for a fan filter holder. I want it to be designed in such a way that the filter can be easily slid in and out, which I think would be best accomplished by having it insert at a 45-degree angle to the fan. The filter will be cut to be just slightly larger than the fan itself - 5mm, specifically. It should be designed so that one side is open for filter insertion, which should be accomplished by having only three attachment points to the fan. The filter holder should have rounded corners with a radius of 10 units.

The design should be fully parametric, so I'll need to be able to adjust the fan size, distance between fan mounting holes, the rounded corner radius, the thickness of the outside plate, the standoff length (which should match the thickness of the filter), and the mounting hole size. When printed, it should have a grid-like surface for airflow, so I'll probably print it with 20% infill and no solid layers. I'll likely use 4 perimeters.

I plan to use 120mm fans as my default, which typically have 105mm of distance between the mounting holes and take 4.5mm screws. A plate thickness of 2mm and a standoff length of 5mm will probably work well, but again, these all need to be adjustable.

Can you provide a parametric OpenSCAD file that uses the MCAD library?

I'm working on a project where I need a way to securely attach bearings and nuts to other parts, like aluminum extrusions. I'd like to design a parametric OpenSCAD file for a universal bearing/nut holder that can accommodate both bearings (circular) and nuts (hexagonal). The design should be flexible enough to function as either an end piece or a center piece.

Here's a breakdown of the key features and parameters I have in mind:

**Functionality:**

*   **End Piece or Center Piece:** The design should allow the user to specify whether the holder is an end piece (meaning it covers one side of the bearing/nut) or a center piece (meaning it allows the bearing/nut to pass through).
*   **Bearing or Nut:** The user should be able to choose between a circular hole for a bearing or a hexagonal hole for a nut.

**Parameters:**

*   **Bearing/Nut Diameter:** The outer diameter of the bearing or nut. It is important to include standard M3, M4, M5, and M6 nut sizes.
*   **Total Width:** The overall width of the holder.
*   **Thickness:** The thickness of the holder. For end pieces, this should be double the bearing/nut thickness, and for center pieces, it should equal the bearing/nut thickness.
*   **Fixing Screw Lower Diameter:** The thread diameter of the fixing screw.
*   **Fixing Screw Upper Diameter:** The diameter of the fixing screw head.

**Additional Design Considerations:**

*   The holder should have a cylindrical base with a rectangular extension.
*   The rectangular extension should have a cutout to allow for a secure fit.
*   There should be a hole for the fixing screw, with a countersunk portion for the screw head.

Could you help me create a parametric OpenSCAD file that implements this design? I don't need any special libraries for this project, just the standard OpenSCAD functionality is sufficient.

Hi! I'm looking for help designing a customizable hole cap in OpenSCAD. I have a few specific requirements, and I'd like to be able to easily adjust different dimensions.

Basically, I have these holes in my sink top left over from old fixtures, and I need a way to cover them up nicely. I'd like to create a circular cap that fits snugly into the hole, with some kind of "teeth" around the edge to help it grip. The design should also have a small flange on top to give it a finished look.

Here's what I need to be able to control:
*   The *external diameter* of the cap – this needs to match the size of the hole I'm covering.
*   The *height* of the part of the cap that goes into the hole.
*   The *thickness* of the cylinder wall that will be inserted in the hole.
*   The number of "teeth" around the edge and how much they protrude (their *extension*).
*   The *height of the top flange* that rests above the sink's surface.

Could you help me generate the OpenSCAD code for this? It'd be great if you could make all of those parameters adjustable. I don't have any preference about libraries to use, but if it simplifies the code, please feel free. I just need it all to be in a single `.scad` file.

I'd like to design a parametric camera mount for a 2020 aluminum extrusion frame, suitable for a Raspberry Pi camera. I'm aiming for something robust and adjustable, and the basic design I'm envisioning has a few key elements:

1.  **Mounting Block:** This will attach directly to the 2020 extrusion. It should have a central hole for mounting to the extrusion and additional holes and recesses for bolting on the other parts of the mount. I'd like it to also have a way to key into the frame so it doesn't rotate easily. M3 screws and nuts will be used, so the block needs to accommodate that.

2.  **Arms:** There will be at least two "arms" that extend out from the mounting block. These arms will connect to the camera mount and should have screw holes/recesses to enable easy mounting/adjusting the angle of the camera. M3 screws should be used here as well.

3.  **Camera Mounting Plate:** I'm planning on something basic - a flat surface with a few mounting holes for a standard Raspberry Pi camera. This should connect to the arms using M3 screws, and I need the freedom to rotate the camera and maybe adjust its height using slots.

4. **Angle Bracket:** I'll need at least one angle bracket to help brace the camera mounting plate. I think this will be necessary for rigidity. It can also be useful for fine-tuning the mounting angle.

I'd like to make this all configurable. I need to be able to adjust things like:

*   **Material Thickness:** This should be a global parameter that affects the thickness of all parts.
*   **Screw and Nut Sizes:** All screw and nut sizes should be parameterized and should take tolerances into account. I'll be using M3 screws and nuts for this project and would like to be able to use different sized screws/nuts later.
*   **Arm Length:** The length of the arms should be configurable.
*   **Camera Mounting Plate Dimensions and Hole Patterns:** Dimensions, mounting hole patterns, and slot length should be configurable for different camera modules.
* **Tolerances:** I need to be able to easily adjust the tolerances for holes and slots.

I'd like to make sure that the mount is easily printable and doesn't require support. I'm using OpenSCAD for this project and would like to leverage common libraries like BOLTS, if that's possible, to make it easier to handle the nuts, bolts, and threads. Could you generate the necessary OpenSCAD files for this project? I'm envisioning at least a few different files so that the project is well organized.

I'm looking to design a Y-axis belt retainer and tensioner for a Prusa Mendel 3D printer. I've got a few ideas and a basic layout in mind.

The design should have two main parts: a base that mounts to the printer frame and a slider that holds the belt. The base needs to have a channel for the slider to move in, and the slider needs to have a groove for the belt. I'd like it to accommodate both T2.5 and T5 belts, with the option to specify which one is used through a parameter. The whole design needs to have a parametric setup for easy modification.

Here's a breakdown of the key features I'm looking for:

**Base:**
*   A rectangular base with a channel for the slider.
*   A way to mount the base to the printer frame using M3 bolts, and include a hex nut trap.
*   A slot for the belt to pass through
*   The base needs to be adjustable in height so the belt runs flat, ideally as a parameter.
*   I would like the base to have a parameter for the overall length, width, and height, and for the internal cavity that houses the slider. I would also like the base to have a parameter for the thickness of the floor and roof as those affect the slider depth.

**Slider:**
*   A rectangular slider that fits snugly within the base channel.
*   A groove for the belt to sit in.
*   A hole for a screw to push against the slider to tension the belt. The screw itself doesn't need to be part of the design, just the hole.
*   I would like a way to cause some "fill" in the cavity so as to not print empty space when the slider is printed.

**Belt:**
*   Include a module for the belt, that can be either T2.5 or T5. The dimensions for the belt are as follows:
    *   **T2.5:** Base Thickness: 1.25mm, Full Thickness: 2mm, Tooth Width: 1.4mm, Space Width: 1.1mm, Belt Width: 6.2mm
    *   **T5:** Base Thickness: 1.5mm, Full Thickness: 2.7mm, Tooth Width: 2.6mm, Space Width: 2.4mm, Belt Width: 6.2mm

**Parameters:**

*   `dRise`: How far the belt is held above the deck.
*   `belt`: A selector for T2.5 or T5 belt.
*   Base Dimensions: `bwExt`, `bwInt`, `blExt`, `blHed`, `bdExt`, `bRoof`, `bFloor`
*   Slider dimensions: `swMax`, `sdMax`
*  Misc Parameters: `wHex`, `dHex`, `rM3`, `sDrop`, `Adjust`, `pWidth`, `pHeight`

I'd prefer a single OpenSCAD file for this with all the necessary modules included. I'm not using any particular libraries, so no need to worry about those. I'm mostly concerned that the design be functional and parametric so it is easily modified for other printers and configurations. I would prefer the module names match the module names in the example SCAD.

I'd like to create a customizable lithophane keychain. I've seen some designs before, but I'd like one where I can control a lot more parameters, and I'd like the code to be flexible and organized.

Here's what I'm looking for:

**Core Functionality:**

*   **Image Input:** The design should take a 100x100 pixel image file as input, likely a `.dat` file generated by an online tool. It should be able to handle stretching the image to fit the keychain shape. I need to be able to control the image's height. The lithophane part needs to have a base layer (it is best when that is white) with a consistent thickness, as well as a number of layers for the varying thicknesses of the grayscale from the image, all based off of the user-defined layer height.
*   **Shape:** The keychain should be able to be either circular or square.
*   **Size:** I need to be able to set the overall size of the keychain.
*   **Ring Hole:** It needs a hole for a keyring, with its size being parametric.
*   **Layer Height:** I need to be able to control the layer height, as that's crucial for 3D printing.
*   **Number of Layers:** The number of layers used to represent the grayscale needs to be settable.
*   **Border:** The keychain should have a border with adjustable width and thickness. I want the border to be a solid piece that attaches to the edge of the lithophane, not just an outline.
*   **Loop:** The keychain needs a solid loop for attaching to a ring. The loop should be integrated into the border and be of set thickness and width.

**Parametric Design Details:**

I'd like to have specific, user-defined variables for the following parameters:

*   `image_file` (string, path to the image data file)
*   `shape` (integer, 0 for circle, 1 for square)
*   `tag_size` (number, overall size of the keychain)
*   `ring_hole` (number, diameter of the keyring hole)
*   `layer_height` (number, layer height for 3D printing)
*   `number_of_layers` (integer, number of layers to represent the grayscale image)
*   `boarder_width` (number, width of the border)
*   `boarder_thick` (number, thickness of the border)

**Code Requirements:**

*   I would like comments in the code explaining how each part of the design is built.
*   It would be great to use descriptive variable names, so the code is easily understandable.
*   I would like to see if you could use the `surface` module with the `file` parameter, that would be very helpful.

I don't have specific library requirements, but I'd like to avoid unnecessary dependencies, so sticking to standard OpenSCAD functions is preferred unless you have a good reason to use a specific library.
