Okay, so I'm looking to create a customizable rack system for storing various cylindrical objects, like spice jars, cans, or even test tubes. I've seen a design that's pretty close to what I want, but I'd like to have it fully parametric so I can easily adjust it for different sized items and layouts. I'd like to have it generate a set of parametric OpenSCAD files.

Here's what I'm envisioning:

**Core Features:**

*   **Individual Compartments:** The rack will be made up of individual compartments, each designed to hold one cylindrical item. This should provide good support and prevent things from easily falling out.
*   **Vertical Mounting:** The rack should be designed to be mounted on a vertical surface (like a wall or cabinet door) using screws.
*   **Hidden Screw Slots:** I'd like the screw holes to be recessed into the back of the rack so the screw heads are hidden from view once it's mounted.
*   **Compartment Size:** I need to be able to easily adjust the compartment diameter to fit my objects, with a tolerance value.
*  **Compartment Depth:** I need to be able to control the distance from the wall to the front of each compartment, with a tolerance value.
*   **Adjustable Height:** I'd need to be able to set different heights for the front and back of each compartment.
*   **Wall Thickness:** I'd need to set the minimum wall thickness of the rack.
*   **Number of Compartments:** The number of compartments in each rack should be adjustable.
*  **Compartment Spacing:** I would like to control the spacing between each compartment.
*  **Bottom Hole:** There should be a hole cut out beneath each compartment, diameter of which should be parametric,
*  **Front Opening:** I want the option to add a gap at the front of each compartment for easy access, where width is parametric.
* **Fillets:** I'd like to be able to define fillets (round edges) where the front and back walls meet the side walls.
*   **Preview:** A cutaway preview option should be available which removes the top section so I can inspect the screw slots.

**Screw Details:**

*   **Screw Hole Size:** I need to specify the diameter of the screw threads, as well as the diameter and depth of the screw head recess.

*   **Screw Slots Placement:** The rack should have the option to add screw slots between compartments and at the ends of the rack.  It needs to be made sure that the screw slots can fit screws without intersecting rack compartments when scaled down in size.

**Dual Extrusion (Optional):**

*   **Stripe Pattern:** It would be really cool if it was possible to create decorative stripes on the rack if I were to use a dual extruder printer.
*   **Stripe Control:** I'd need to control the orientation and number of the stripes.  I'd like some preset options where the striping links the rack dimensions to the stripe count or I'd like the option to use custom dimensions and angles
* **Split Output:** To do this, the rack would need to be able to be output in two STL files, one with the main rack body and another with the stripes, so I can merge them in my slicer.

**Specific Parameters:**

I'm thinking that I should be able to set these parameters (using these names in the SCAD code):

*   `diameter` (diameter of the jar/object + tolerance)
*   `hight_back` (height of the back wall)
*   `hight_front` (height of the front wall)
*   `wall_thicknes` (minimum wall thickness)
*   `number_or_comsplitments` (number of compartments)
*   `extend` (additional distance between compartments)
*    `back_depth` (additional distance from wall to compartments)
*   `screw_diameter` (diameter of the screw threads)
*   `screw_head_diameter` (diameter of the screw head)
*   `screw_head_depth` (depth of the screw head recess)
*   `screw_slots_middle` (0=NO, 1=YES - add screw slots between compartments)
*   `screw_slots_ends` (0=NO, 1=YES - add screw slots at either end)
*    `bottom_hole_diameter` (value between 0 and 1, where 0=no hole, 1=no floor)
*    `front_opening_width` (adds a gap at the front, 0=no opening)
*   `show_cutaway` (0=NO, 1=YES - shows a cutaway preview)
*   `split` (0=NO SPLIT, 1=SPLIT PART ONE, 2=SPLIT PART TWO - for dual extrusion)
*  `stripe_preset` (0=NO preset, 1=TOP-BOTTOM, 2=SIDE-SIDE, 3=FRONT-BACK)
*   `stripe_number` (number of stripes, for presets)
*   `custom_stripe_width` (only works if stripe_preset=0)
*   `custom_rotate` (custom rotation, works if stripe_preset=0, [x, y, z])
*   `custom_offset` (moves stripes, works if stripe_preset=0)

It would also be good if the design used more abbreviated variable names to keep the code readable, and some tolerances for added flexibility.  Please also add comments to make the code more easily understood.

I think that covers everything I need. I would like a set of parametric scad files, rather than just one. Could you create that for me?

I'd like to design a parametric model of a Samsung Gear 360 camera in OpenSCAD. I'm not sure if it needs to be multiple files, but I'd like a primary file that can be used to control the overall look and feel of the model. I'd like to be able to adjust things like the overall size and proportions, the quality of the curves (using `$fn`), and the size and placement of individual components, and I'd like to be able to toggle the display of various parts. The core of the design should be the main body, which is a kind of flattened sphere, with two circular lenses/bezels on each side. It also has a few features around the base, including a 1/4" screw mount cutout, a battery lid, a few side buttons, LED indicators and a display panel on the top with a button.

Specifically, the following should be adjustable:

*   **Overall Size:** A primary scaling factor to control the overall dimensions.
*   **Curve Quality:** Independent `$fn` multipliers for the main body and for smaller details, allowing for control over the polygon count of the curves.
*   **Main Body:** The main body is a flattened sphere with a central cylinder cutout and should be controllable for width and height.
*   **Lens/Bezel:** The size and position of the lenses and bezels should be configurable, including lens protrusion from the body.
*   **Screw Mount:** The size and position of the 1/4" screw mount cutout.
*   **Battery Lid:** The size, position, and curvature of the battery lid on the side of the body.
*   **Side Buttons:** The size and position of the side buttons along the sides of the body.
*   **LEDs:** The size, color, and position of the indicator LEDs. I would like to be able to have several LEDs and control their color.
*   **Display Panel:** The size and curvature of the top display panel and the button. The display should have a rectangle cutout with rounded ends and it should be raised on a platform with a slight curve.
*   **Material/Color:** Parameters should control the colors of main body, the bezels, the lens, and the led lights. I would also like to include some basic transparent colors.

I think the core model should be made using `rotate_extrude` from a 2D shape, with simple primitives for other components, plus some hulls here and there.

I don't have a preference for specific libraries, but I would be very happy with `BOSL` or `BOSL2` if you find that helps with the more complex shapes.

Hey, I'm looking to design a customizable 2D parrot model in OpenSCAD, similar to the example I saw on Thingiverse. It should be parametric, letting me control the overall size, height, and the thicknesses of the inner and outer outlines.

Here's what I need:

*   **Overall Size:** I want to specify the maximum size of the longest side, and the shorter side should automatically resize proportionally.
*   **Height:** I need to be able to set the model's height (thickness).
*   **Outlines:** There should be a parameter for the thickness of the outer outline, and another for the thickness of the inner outlines.
*   **Inner Outline Edges:** The inner outlines should have rounded ends, and I'd like to be able to control the radius of that rounding.
*   **Flip:** A parameter to flip the model horizontally.

The parrot's shape will be defined by a set of outer points, and a set of inner polygons. I can provide those exact coordinates. I need the code to calculate scaling factors from the given coordinates, so that it is parametric on `max_size` and the coordinate information does not need to be manually adjusted when `max_size` changes.

I think the process is something like:
1.  Define all the outer and inner polygons given in the source SCAD.
2.  Scale the coordinates using `max_size` as a parameter.
3.  Create the outer outline using an offset of the given outline polygon.
4.  Create the inner outlines via offsets of the inner polygons
5. Extrude to the specified height.
6. Apply flip transformation if necessary.

I do not need to rely on external libraries, since the design is fairly simple.

I'd like to design a parametric pull handle for a workshop, intended to be used with various diameters of tubes or bars. I've been working on it, and I have two versions of the .scad file (included), but I'd really appreciate it if you could start fresh and design these from the ground up, focusing on better organization and clearer design.

Here's what I'm looking for:

1.  **Parametric Tube Diameter:** The primary parameter should be the diameter of the tube or bar that will be used as the pull handle itself (`diameter_pull_bar`). I'd like to include a bit of extra clearance for shrinkage when 3D printing, so maybe add that to the parameter, or keep it as a separate parameter like my previous designs. Default should be 15.4 mm.

2.  **Screw Hole Diameter:** A second parameter should set the diameter for the screw holes (`screw_dia`). I'd like to be able to easily adjust this for different screw sizes. Default should be 4.5 mm.

3.  **Show Parts Options:** I'd like to be able to select different views of the handle, like my previous versions.  Specifically, I'd need the following options:
    *   `show_parts = 1`: Show a single handle part.
    *   `show_parts = 2`: Show an assembled view, with a section cut through one handle and a whole handle next to it.
    *  `show_parts = 3`: Show a pair of whole handles.
    *  `show_parts = 4`: Show a single handle oriented for easy 3D printing (with a flat base).

4.  **Clear Construction:**  I'm aiming for the handle to be constructed from a base that's essentially a half-cylinder with a cylindrical cutout for the tube handle itself. I also need to include a mounting base on either side, with a countersunk screw hole for each. I want the screw holes to be angled to meet the horizontal base.

5.  **Watertight Model:** Please ensure that the final model is watertight for easy 3D printing.

6. **No Libraries Required** I'd like to keep this as simple as possible and avoid using any external libraries.

Could you design this for me using these specifications, paying special attention to the organization of modules and clarity of code?  I want it to be well-structured and easy to read.

I'd like a customizable OpenSCAD design for a 2D Makkuro, similar to the one on Thingiverse but with a bit more flexibility.  I need to be able to set the maximum size of the longest side, and the shorter side should scale proportionally.  I also need to control the overall height, and the thicknesses of both the outer and inner outlines, as well as the radius of the inner outline corners. I want to be able to flip the design horizontally too.

I'm picturing a design based off of provided coordinates for the outline, and coordinates for inner cutouts. The provided coordinates are given in the original SCAD file, so the generator should be aware that these should be scaled according to the `max_size` parameter. The design should then generate a 2D profile.

I'm not using any libraries at the moment, and don't plan to, but if a library would help please use it (e.g. a library for scaling and transformations, or for handling polygons).

I'd like to design a customizable thumb wheel for screws, and I have a fairly clear idea of what I want it to look like, but I need help creating the OpenSCAD code.

Here's what I envision:

The thumb wheel should have a cylindrical body with a textured outer surface for grip and graduations marked on the top surface. It will also have an internal recess to fit a standard nut. There will be a through-hole for the screw, and a chamfer along the top and bottom edges for a nice feel.

Specifically, I need the following parameters to be customizable:

*   `nut_diam`: The outer diameter of the nut that the thumbwheel will be upgrading.
*   `nut_height`: The height/thickness of the nut.
*   `screw_diam`: The diameter of the screw.
*   `wheel_diam`: The overall diameter of the thumbwheel.
*   `wheel_height`: The full height of the thumbwheel, including the nut collar.
*   `wheel_thick`: The thickness of the main part of the thumbwheel (excluding the nut collar).
*   `grad_num`: The number of major graduations around the thumbwheel.
*   `lip_height`: A small height of a lip that holds the nut.
*   `lip_thick`: The thickness of the lip holding the nut.
*   `press_fit`: The tolerance for the press-fit of the nut (likely a small negative number for the nut to be very snug).
*   `engrave_depth`: The depth of the engraved graduations.
*   `grip_num`: The number of grips around the edge of the thumbwheel.
*    `grip_diam`: The diameter of the individual grips.
*    `grad_sub`: The number of sub-divisions between major graduations.
*    `mgrad_diam`: The diameter of the main graduation indicators
*    `grad_diam`: The diameter of the main graduation marks
*    `recess_diam`: The diameter of the recessed area on the top.
*   `recess_height`: The height of the recessed area on the top.

I'd like the grip to consist of small cylinders protruding from the thumbwheel's circumference. Also, there should be main graduations and smaller, sub-divisions of graduations around the circumference of the top face. I want the nut to sit in a snug pocket and also have an entry clearance pocket, all cut out from the base of the thumbwheel. Finally, the chamfer should look nice, giving the thumbwheel a smooth beveled edge.

I think this can be made by starting with a cylinder and then subtracting a series of other cylinders and shapes to create the final geometry. I'd also like to use the `for` loop to generate the grips and graduations. I'm not using any external libraries but I’d like all of the math to be calculated inside the single `.scad` file for ease of use and portability. Could you create an OpenSCAD file for this design?

I'm looking to create a customizable origami-style seal design using OpenSCAD, similar to the one I saw on Thingiverse. I need a parametric design where I can adjust the overall size, the model's height, and the thickness of both the outer and inner outlines. The design should also include the rounded edges for the inner outline, and ideally, a feature to flip the model for printing purposes.

The seal's outline and internal cuts should be based on the points specified in the existing SCAD file. I've included the points below:

```
// Outer Points

```
I'd prefer the main logic to be contained within a single file. I'm expecting to define a max size, a height, outline sizes, and edge radius. The design should be able to scale proportionally based on the max_size parameter, with a flip model feature. I won't be using any external libraries for this project.

I'd like a customizable OpenSCAD design for a 2D origami-style rhino, similar to the one I saw on Thingiverse. I need to be able to adjust the overall size, the height of the model, and the thickness of both the outer and inner outlines. The inner outlines should also have rounded edges. I'd like an option to flip the model horizontally, too.

The main shape is defined by a series of 2D coordinates, and then "cut" out by a series of polygon shapes, so you can think of it as one outline being offset inwards by a given amount and then further by a given amount again, but this time as a shape with rounded edges.

The coordinates for the outer outline points are:
A1 = [5, 194];
A2 = [195, 0];
A3 = [396, 0];
A4 = [397, 16];
A5 = [1145, 14];
A6 = [1145, 4];
A7 = [1242, 4];
A8 = [1337, 98];
A9 = [1337, 137];
A10 = [1529, 261];
A11 = [1698, 219];
A12 = [1630, 329];
A13 = [1823, 455];
A14 = [1860, 138];
A15 = [1996, 566];
A16 = [1795, 735];
A17 = [1346, 659];
A18 = [1347, 781];
A19 = [1337, 963];
A20 = [1251, 963];
A21 = [1205, 914];
A22 = [634, 692];
A23 = [398, 814];
A24 = [394, 963];
A25 = [115, 963];
A26 = [3, 443];

The inner polygon shapes are defined by these points:
B1 = [398, 595];
B2 = [1144, 829];
B3 = [1341, 563];

And the polygon cutting shapes are made from a combination of A and B points, as follows:
C1 = [A25, A26, A1, A2, A3, A4, B1, A23, A24];
C2 = [B1, A22, A23];
C3 = [A4, A5, B2, A21, A22, B1];
C4 = [A6, A7, A8, A9, B3, B2, A5];
C5 = [A9, A10, A12, A13, A16, A17, B3];
C6 = [A10, A11, A12];
C7 = [A14, A15, A16, A13];
C8 = [B3, B2, A21, A20, A18, A17];
C9 = [A18, A20, A19];

I'm not using any specific OpenSCAD libraries that I'm aware of, so please don't rely on any for this design. Thanks!

Okay, I'd like a parametric design for a beermat stand, similar to the one I saw in the provided code. I want to be able to customize it for different sized beermats and stack heights.

Here are the main things I'm looking for:

*   **Beermat Dimensions:** The design should have parameters for the width of the beermat (`$mat_width`) and the desired height of the stack of beermats (`$mat_stack_height`).
*   **Cover Height:** I need a parameter for how much of the beermat stack the stand should cover, I saw it called `$mat_height_cover`.
*   **Wall Thickness:** A parameter for the thickness of the walls (`$thickness`).
*   **Decorative Feet:** The design should have some feet, which should be customizable for thickness (`$deko_thickness`) and width (`$deko_width`). I need the feet to be positioned at each of the four corners of the base.
*   **Wall Angle:**  I want to be able to control the angle of the side walls (`$angle`).
*   **Rounded Corner:** The design should have a rounded inner corner where the base of the beermats rest. The design I was working with used `$curve_offset` to control the size of the curve, and I like that.
*   **Support Rods:** I need support rods running vertically along the back and the front of the stand, near the edges, just to be safe, something like two cylinders in the original code, but I need those parameters configurable (e.g. diameter, radius)

I'd like the design to be a single OpenSCAD file, with all the parameters at the top of the file for easy customization. Please use the `difference` function to cut out the space for the beermats, and use `linear_extrude` for the basic box shape. Feel free to use any other modules to organize the design.

I'd like to design a customizable coaster with a QR code on it that encodes WiFi credentials. It should also have the SSID and password printed in plain text, and have a cavity to hold an NFC sticker. I'm aiming for a design that’s easy to customize through parameters, so I'd like it to be parametric. I'd like you to create the OpenSCAD file(s) for this.

Here are the details:

*   **Overall Shape:** It should be a square coaster with rounded corners.
*   **Size:** The width and height should be configurable parameters.
*   **Base:** There'll be a base layer with a configurable thickness for the main part of the coaster. This is likely meant to be printed in a light color.
*   **Border:**  There should be a raised border around the edge, also with rounded corners, and with a configurable width. The inner corners of the border should also be rounded.
*  **QR Code:** The QR code should be inset into the surface, and have a configurable thickness. The QR code data itself will be an array of arrays, which I'll provide. The size of the QR code should be automatically calculated based on the size of the coaster and borders and margins around it. There should also be configurable margins around the QR code.
*   **Text:** The SSID and password should be printed on the surface, above and below the QR code respectively. Text size, margins, and line spacing should all be configurable, as well as a configurable font and style.
*  **NFC Cavity:** There will be a rectangular cavity in the base for an NFC sticker, with configurable size.
*   **Wireless Logo:** There's a configurable option for whether or not to embed a simple wireless logo into the center of the QR code.
*   **Color Changes:** I will handle color changes manually, but the design should accommodate a layered printing approach with a black QR code and text, and a white base.
*  **Libraries:** I don't have any particular need for any libraries, so you're fine without them. I can write my own `rcube` function.

I'll need parameters for the following, at a minimum:

*   `SSID` (string)
*   `PASSPHRASE` (string)
*   `WIDTH` (number)
*   `HEIGHT` (number)
*   `BASE_THICKNESS` (number)
*   `BORDER` (number)
*   `QR_THICKNESS` (number)
*   `MARGIN` (number)
*   `TEXT_SIZE` (number)
*   `LINE_GAP` (number)
*   `TEXT_MARGIN` (number)
*   `ROUNDED_CORNERS` (number)
*  `INNER_ROUNDED_CORNERS` (number)
*   `WIRELESS_LOGO` (boolean)
*   `NFC_SIZE` (3-element vector)
*   `QR_DATA` (array of arrays, each row being a list of 1s and 0s)

Could you generate the OpenSCAD code for this?

Hey, I'm looking to create some replacement coding blocks for my Cubetto playset. I've seen some online, but I want to be able to tweak them parametrically. I'd like to generate OpenSCAD files that let me define different tile types (like "forward," "left," etc) and control the magnet hole placement based on some configurable parameters.

Here's the basic idea:

1.  **Tile Shapes:** The tiles have a base shape and a stub that connects to the Cubetto board. I want to import the 2D shapes of the base tile and stub from a DXF file; I'll provide that. It should have layers named after the tile type and one named "stub".

2.  **Magnet Holes:** Each tile needs magnet holes on the back. These holes should be cylinders that go a specific depth into the tile, positioned according to a table mapping a tile type to the pattern of magnet holes. The holes need to be placed in the 3D space. I'll provide the layout of positions for the 3 available positions for magnets.

3.  **Parameters:** I'd like these parameters to be easily adjustable:
    *   `h_base`: Height of the tile base.
    *   `h_stub`: Height of the stub.
    *   `h_magnet`: Height of the magnet holes.
    *   `wiggle`: A small adjustment for magnet holes to allow easy magnet insertion.
    *  `scalefactor`: A scale factor because my DXF is in mm but I want the tiles in the right size.
    * `dxffile`: The name of the DXF file to import.
    * `tilearray`: The names of all the tiles, in order.
    * `tilemagnets`: A matrix which specifies which of the 3 possible magnet locations should be used for a given tile.
    * `tilemagnetholes`: The 3 magnet positions for all the tiles.

4.  **Tile Types:** I need the following tile types: "right," "left," "subprogram," "forward," "backwards," "negation," and "random". The design should be modular, so it's easy to add more later.

5.  **Output:** The design should either output the individual tiles or output all of them laid out for printing purposes. I'd like an option to pick either.

Could you generate the OpenSCAD files that can handle all of this?

Thanks!

Hi, I'm looking to create a parametric OpenSCAD library for generating structural aluminum extrusion profiles, specifically 2020, 2040, and 2080 types. I've seen a few different approaches, and I'd like one that I can easily customize.

The key parameters should include:

*   **`extrusionSize`**: A string parameter that lets the user choose the extrusion type ("2020", "2040", or "2080").
*   **`extrusionLength`**: A numerical parameter for the length of the extrusion.
*   **`slotWidth`**: A numerical parameter to control the width of the T-slots.
*   **`cornerRadius`**: A numerical parameter for the radius of the four outer corners.
*   **`centerDia`**: A numerical parameter for the diameter of the central hole(s).
*   **`slotGap`**:  A derived parameter, but it should be configurable through `slotWidth`. It's equal to `slotWidth + 0.26`.
*    **`slotMax`**: A fixed parameter at 11.99, representing the largest point of each slot.
*   **`centerSquare`**: A fixed parameter at 7.31, for the size of the square in the center of the profile.
*   **`wallThickness`**: A fixed parameter at 1.5, for the thickness of the extrusion walls.
*    **`extrusionWidth`**: A fixed parameter at 20.
*   **`extrusionHeight`**: A fixed parameter at 20.

The 2020 profile is basically a square with rounded corners, four T-slots, a central hole, and four connecting circle walls. The 2040 is two 2020s stacked with a connecting bar and a central connecting cavity. The 2080 is two 2040s stacked with a connecting bar, and a central connecting cavity.

The code should generate the appropriate profile using `linear_extrude` based on the `extrusionSize` parameter. The T-slot geometry should be accurately modeled, using a difference between a square and a couple of angled smaller squares. Additionally, include `roundedSquare` module, and include a `joinerCutout` module for the 2040 and 2080 profiles, but not the 2020. This is basically a square with rounded corners with some additional subtracted pieces.

I'm not sure what libraries you'd be using, but I'm assuming some basic shapes are available. I don't want to use anything external, just vanilla OpenSCAD. Can you provide the complete code for this?

I'd like to create a customizable 2D turtle design using OpenSCAD. The design should be based on the provided coordinates, which outline both the outer shape of the turtle and the inner cut lines. I need to be able to adjust several parameters:

*   **Maximum Size:** I need to control the overall size of the turtle, with the longer side scaling up to a specified value. The shorter side should scale proportionally to maintain the aspect ratio.
*   **Model Height:** The height of the extruded turtle should be adjustable, which would essentially control the thickness of the final print.
*   **Outline Thickness:** I need to specify the thickness of the outer outline of the turtle.
*   **Inner Cut Line Thickness:** I also need to set the thickness of the inner cut lines.
*   **Inner Cut Line Roundness:** The ends of the inner cut lines need to be rounded, and I need to adjust the radius of that rounding.
*  **Flip model:** I want to be able to flip the model, like a mirror image.

The attached SCAD file has the basic points, but I need a new file that takes these parameters and renders the turtle with the correct geometry. The output needs to be a solid 2D shape (extruded). Please generate the OpenSCAD file for this. I don't need any particular libraries. I'm hoping the assistant will be able to read the SCAD file I included and understand what I need.
