Hey, I'm looking for an OpenSCAD design for a coin holder, and I'd like it to be parametric.

I need it to hold five different Euro coins: 2 euro, 1 euro, 50 cent, 20 cent, and 10 cent. The diameters are roughly 25.75mm, 23.35mm, 24.25mm, 22.75mm, and 19.75mm respectively, and I'd like the height of each slot to be customizable. I'll need to be able to choose from a few different layouts: a circular arrangement, an arc arrangement, a straight line, and a 3x2 grid.

Additionally, I'd like to control whether there is a hall or lip around the bottom of the coins, and whether a number indicating the coin's value appears on the base of each holder. The base height and base extension around each coin should also be customizable parameters.

I'll also need the ability to specify the wall thickness and `fn` value for the number of segments for each round object.

I'm using the `text_on.scad` library for adding text to the design. Could you please generate the appropriate SCAD files to achieve this design? I'm envisioning it all being in a single file for simplicity.

I'm looking to design a bracket for my DIY solar panels, and I'd like it to be parametric so I can easily adjust it for different panel sizes. I have a few specific design ideas I'd like to incorporate, and I'd like the bracket to be printable on a typical FDM 3D printer.

Essentially, the bracket should cradle the solar panel, leaving a small gap around the perimeter, allowing the panel to be attached with a bit of adhesive or hot glue. I'd also like to include features that allow for fabric straps to be run underneath the panels, so they can be connected to one another along the length. This will let me fold up the panels for transport and prevent damage to any delicate connections on the underside of the panel.

Here are the specific dimensions and parameters I'm imagining:

*   **Panel Dimensions:** I'd like to define the panel's X and Y dimensions (solar\_X and solar\_Y). I anticipate the X dimension will usually be the larger one, so that's where I'd like the straps to run. I would like to be able to define these parameters as input variables to the OpenSCAD file.
*   **Fabric Gap:** The space where the fabric straps will run underneath needs to be adjustable (fabric\_gap), ideally a small gap on the sides of the bracket.
*   **Base Thickness:** The base of the bracket needs to have a specific depth (bracket\_base\_depth). This might be adjustable in the future, so it would be nice to have it as a parameter.
*   **Panel Taper:** My solar panels have a slight taper to them. It may or may not be necessary to model this into the bracket, but it might be useful to have as a variable for my design needs. The panel thickness tapers from a maximum (solar\_Z\_max) to a minimum (solar\_Z\_min). I might not need these, but it's worth having. These parameters should have some effect on how the panel sits in the bracket. The panel also has a slope from the thinnest to the thickest, and it would be good to have some offset related to that (solar\_slope\_offset).
*   **Cutout Offset:** I want the bracket to have a cutout area underneath to reduce the material used (bracket\_cutout\_offset).
*   **Wall Overhang:**  I want to define the overhang amount on the outer walls (wall\_overhang).
*   **Wall Depth:**  The depth of the outer walls should be settable (wall\_depth).
*   **Side Overhang:** The amount of overhang on the sides should also be adjustable (side\_overhang).
*   **Fudge Factor:** This could be useful for making small adjustments to the model if it's not quite fitting right. It should be a very small number (fudge)
*   **$fn:** I would like to have the ability to adjust the circle resolution using `$fn`

I'm looking for a parametric OpenSCAD file, or files, that can generate this bracket design. I can provide more details later on if necessary. I also would like to avoid using libraries if possible. I'm really looking for simplicity of design and customizability using simple variables.

Hey, I'm looking to get a custom vacuum crevice tool designed in OpenSCAD. I found this existing design (Customizable_Vacuum_Crevice_Tip_With_Offset.scad) which is close but I need a few things changed, and ideally, a cleaner implementation.

The basic idea is a cylindrical base that attaches to a vacuum hose, connected by a chamfered section to an offset rectangular nozzle with rounded corners. The original design has several key parameters:

*   **`Base_Diameter`**: Diameter of the vacuum cleaner pipe connection.
*   **`Base_Overlap`**: Length of the pipe that overlaps the vacuum cleaner pipe.
*   **`Base_Chamfer_Length`**: Length of the chamfered section between base and nozzle.
*   **`Base_Thickness`**: Material thickness at the base.
*   **`Nozzle_Length`**: Total height/length of the nozzle.
*   **`Nozzle_Outer_A`**: First dimension of the nozzle's outer rectangular cross section.
*   **`Nozzle_Outer_B`**: Second dimension of the nozzle's outer rectangular cross section.
*   **`Nozzle_Fillet_Radius`**: Radius of the rounded corners on the nozzle.
*   **`Nozzle_Thickness`**: Material thickness of the nozzle walls.
*   **`Nozzle_Chamfer_A`**: Depth of the chamfer at the nozzle tip (along the `Nozzle_Outer_A` dimension).
*   **`Nozzle_Chamfer_B`**: Length of the chamfer at the nozzle tip.
*   **`nozzle_offset`**: Distance the nozzle is offset from the center of the base.

I'd like a couple of key improvements to be made:

1.  **Better Variable Management:** It seems like the old code has a bunch of variables with trailing underscores, which can be confusing and it'd be nicer to have a more streamlined way of handling these, ideally so that there's a more robust way to handle edge cases where parameters conflict (maybe just a `clamp()` function, or equivalent).
2.  **Explicit Chamfering:** The old code uses a really clunky way to create the base and nozzle chamfering with linear_extrude and scaled shapes, and I'd rather have that done explicitly and perhaps with a more "correct" implementation (e.g. using a `rotate_extrude()` in a couple of cases).
3.  **Clearer Module Names:** The `make_base` and `make_nozzle` module names are okay, but maybe we could have more descriptive names (like `create_base` or `create_nozzle`) or more specific, depending on what makes sense given the approach.
4.  **Full Parametricity**: I want to make sure that absolutely *everything* is parametric so that I'm not getting any clipping or errors like in the original design.
5.  **Fillet Limitations**: I noticed that the fillet radius is limited by the nozzle dimensions which makes sense, but would be good to know that that is something being checked or accounted for in some way.
6. **Error Checking**: Can you make sure that there are sufficient error checks so that I don't accidentally request configurations that can't be built?

I don't really have any special library requirements, so just whatever seems most appropriate would be fine. I'm open to how you want to structure the code and how the modules are defined. Thanks!

I'm looking to design a case for my WeMOS D1 Mini stack of shields, and I'd like to use OpenSCAD to make it parametric. I have a main board, and then a couple of shields on top of that.

The core of the case needs to be able to be adjusted by height to account for different numbers of stacked shields. I'd also like to be able to specify the vertical offset of cutouts for the various ports on these shields. I'm thinking about being able to specify the height from the bottom of the case to the bottom of the cutout, and a height of 0.0 to omit.

Here are the parameters I think I need:
*   `height`:  The total height of the case walls.
*   `usb_height`:  Distance from the bottom to the bottom of the USB connector opening (0.0 to omit).
*   `microsd_height`: Distance from the bottom to the bottom of the microSD card slot opening (0.0 to omit).
*   `battery_height`: Distance from the bottom to the bottom of the battery shield connector opening (0.0 to omit).
*   `relay_height`:  Distance from the bottom to the bottom of the relay shield terminal opening (0.0 to omit).

I'd like the case to consist of two parts: a base and a lid. The lid should have a slight overlap with the base, and I'd like it to include some features to snap the two pieces together, like small tabs or posts and mating holes. For the base, I'm also imagining a small hole in the base near the center for a screw for optional securing, and a couple of cutouts on the side for cables and other potential use.

I don't have any other specific libraries I want you to include, so you can write the SCAD files from scratch. I need a `.scad` file for the case.

// WeMOS D1 Mini Stack Enclosure Script
//
// I wrote this script to generate a suitable 3-d printed enclosure for a WeMOS "stack" of shields.
// Since there are a variety of connectors, sizes and arrangements, I decided to let the customizer
// allow for various positionings of each shields port.
//
// To use, you will need to assemble your device and measure the total height of the case, and the
// height offsets for any shields that require an opening in the case.
//
// For instance, I have a WeMOS D1 Mini with a battery shield and then an SD Card shield on top of
// that.  All have stackable headers, that have had their pins trimmed to make the stack as short
// as possible.  The resulting measurements of the stack yield the default values of this script.

I'm looking to create a customizable 6-piece burr puzzle generator in OpenSCAD. I've seen some existing code, but I'd like something that is more flexible and allows for a wider range of piece types beyond the standard 25 notchable pieces. Here are the key things I'd like the generator to be able to do:

**Core Functionality:**

1.  **Parametric Stick Definition:** I want to be able to define the stick length, unit size, gap size for tolerance, and a rounding radius for the edges. These should all be configurable with reasonable default values. I'd also like to have a few options for the base model shape: rectangular, rounded, carved (with a center channel removed), and pointed.

2.  **Piece Definition:** The core of the puzzle is a stick with sections removed. I need a way to define which 1x1x1 cubes are removed from the 2x2x(length) "stick". The existing code does this using a 12-bit number representing which cubes to cut, but I'm open to other ways that might be more intuitive, such as a way to define removals directly. I definitely need it to be able to make the 25 standard notchable pieces at a minimum.

3.  **Predefined Sets:** I want to be able to easily define and generate predefined sets of pieces for common burr puzzles (like the Chinese Cross, Diabolical Structure, etc.) and also have the option to add my own sets. I also need the ability to print out all of the 25 notchable pieces, or the 42-piece set with duplicates to allow building all of the known solid burrs.

4.  **Single Piece Generation:** I also need to be able to generate individual pieces by specifying their piece number or by another, more user-friendly, removal specification method.

5.  **Assembly/Placement:** Ideally, the program would not only generate the individual pieces, but it would also optionally generate an assembly of the selected sets, placed in their approximate solved positions. I know this can be quite difficult, but it would be a great feature. If this is too complicated to include as a default, I'd still like the option to generate separate pieces with a simple positioning scheme for a complete set.

**Specific Parameters:**

*   `stick_length`: Integer length of the stick (default 6, range 5-18)
*   `unit_size`: Size of one unit in mm (default 8, range 4-12)
*   `gap_size`: Gap for printing tolerance (default 0.2, range 0.1 - 0.4)
*   `rounding_radius`: Radius for rounded edges (default 1.6, range 0-2.4)
*   `base_model`: Choice of stick base (0: Rectangular, 1: Rounded, 2: Carved, 3: Pointed)
*   `chosen_set`: Integer to choose from a predefined set of puzzles.
*   `chosen_piece`: Integer to choose from a predefined set of the 25 notchable pieces.
*   `piece_number`: Integer to choose any arbitrary piece number.

**Libraries:**

I'm not sure if any are necessary, but if you're planning on using any libraries, I'd like you to specify them. Otherwise, if you can do this using just the core OpenSCAD language, that's perfect too.

**Output:**

I'm fine with separate STLs being generated for each piece, whether as a set or individual components. If you can put together an assembly using a simple placement layout, I'd like that as an option as well.

In summary, I want a flexible, parametric generator that can create a wide variety of burr puzzle pieces and assemble predefined sets. I'm looking forward to seeing what you come up with!

A Burr piece is made of a standard 6x2x2 cube from which
sections are removed. The number n to the module
burr_piece(n) is a 12 bits binary number. If a bit is
set (one) the corresponding 1x1x1 cube is removed from
the base piece. 1024 and 2048 are hidden behind 256 and
512.

Hi, I need a parametric OpenSCAD design for an enclosure for my NodeLHC project. I've got a basic design already in OpenSCAD, but it's a bit messy, and I'd like to make it properly parametric and more flexible.

Here's the breakdown of what I need:

**Core Components:**

*   **Box/Base:** This is the main part of the enclosure that houses the electronics. It should have an interior space to accommodate a PCB with the following general dimensions:
    *   Length: 45 mm
    *   Width: 26 mm
    *   Height: 9.5 mm (this height might need to vary slightly based on a capacitor height, but I'll need the option to adjust this).
*   **Lid:** A lid that fits snugly on top of the box. It should be 3mm high, but that should be a configurable parameter.
*   **PCB:**
    *   Thickness: 2mm
    *   It has a few elements:
        *   2 push buttons, diameter 6mm, located a configurable distance from the side walls. (Default: 3mm).
        *   A USB port, size 9.2x7.7x3.7mm, at the center of one side of the box with some optional cutout for connector pins.
        *   A capacitor, diameter 4mm, height 5.4mm, two of them
        *   An ESP chip (24x16x1mm) with chip part(15x12x2.5mm)
        *   LDO (3.7x6.6x1.6)
        *   FTDI (10.3x5.3x1.6)
*   **General:**
    *   Wall Thickness: 1mm (This needs to be configurable).
    *   3D printing tolerance: I would like to configure this error and apply it to all sizes that can change with printer error, this error needs to be applied at the wall thickness, for both the main box and lid.
    *   Corner Supports: I want support structures at each corner of the box. These should be configurable size.

**Parameters I want to control:**

*   **Printer Error XY:** This value will add an error on the X and Y axis of every print, to allow correct fit between different parts.
*   **Mode:** Either "View" for rendering the parts to check visually, or "Print" for generating files for 3D printing
*   **PrintLid:** A boolean to enable/disable the generation of the lid.
*   **PrintBox:** A boolean to enable/disable the generation of the box/base.
*   **CutButtonsInLid:** A boolean to enable/disable cutouts in the lid for the push buttons.
*  **CutHotAirSinkInLid:** A boolean to enable/disable a cutout for a hot air sink in the lid, should be generated using a circle array.
*   **CutLeftPinsInBox:** Boolean to add a cutout for left pins in the base, when viewing the box with the USB port on the front.
*   **CutRightPinsInBox:** Boolean to add a cutout for right pins in the base, when viewing the box with the USB port on the front.
*   **CustomCutBox:** Boolean to add a custom rectangular cutout in the box
*   **CustomBoxCutSizeX:** Custom cut size X in box
*   **CustomBoxCutSizeY:** Custom cut size Y in box
*   **CustomBoxCutOffsetX:** Custom cut offset X in box
*   **CustomBoxCutOffsetY:** Custom cut offset Y in box
*  **CustomCutLid:** Boolean to add a custom rectangular cutout in the lid
*   **CustomLidCutSizeX:** Custom cut size X in lid
*   **CustomLidCutSizeY:** Custom cut size Y in lid
*   **CustomLidCutOffsetX:** Custom cut offset X in lid
*   **CustomLidCutOffsetY:** Custom cut offset Y in lid
*   **Wall thickness:** thickness of wall, default 1 mm.
*   **Lid Height:** height of lid, default 3 mm
*   **Base Height:** Height of base box
*   **Box Length:** length of base box.
*   **Box Width:** width of base box.
*   **LDO/FTDI Clearance:** A clearance value between the LDO and FTDI, default 0.5mm
*   **PCB Thickness:** Default 2mm
*   **Push Button Size:** Default 6mm
*   **Push Button Height:** Default 4mm
*   **USB Offset X:** offset of USB connector
*   **USB Size X:** size of USB connector X
*   **USB Size Y:** size of USB connector Y
*   **USB Height:** Height of USB connector
*   **Capacitor Diameter:** capacitor diameter
*   **Capacitor Height:** capacitor height
*   **ESP Size X:** width of ESP module
*   **ESP Size Y:** Height of ESP module
*   **ESP Chip X:** width of ESP chip on board
*   **ESP Chip Y:** height of ESP chip on board
*   **ESP Chip Height:** height of ESP chip on board
*   **LDO Height:** Height of LDO
*   **LDO Size X:** width of LDO
*   **LDO Size Y:** height of LDO
*  **FTDI Height:** height of FTDI
*   **FTDI Size X:** width of FTDI
*   **FTDI Size Y:** height of FTDI

**Specific Design Requests:**

*   The box should have an interior that matches the PCB.
*   I want cutouts for the USB port, buttons and optional hot air sink cutout.
*   The corner supports should be added to the bottom of the base and should extend until the PCB height to support the PCB from bottom.
*   I need the ability to add custom rectangular cutouts in both the box and lid.
*   The lid should fit on the box correctly with the specified 3D printing tolerance.
*   The box base should have optional cutouts for ESP32 pins and all electronic components should be rendered.

I think that covers it all. Could you generate the OpenSCAD files for this? I don't need any included libraries, thanks.

Hey! I'm looking to create a modular hex tile system for board games, and I'd like to use OpenSCAD to generate the tiles. I've got some ideas about the kind of tiles I want to be able to make, and how they should fit together, but I'm not great at OpenSCAD. Could you help me design a set of parametric OpenSCAD files to do this?

Here's what I'm thinking:

1.  **Basic Tile Shape:** I need a standard hexagon tile, with a flat top and bottom, designed to be stackable. I'd like to control the overall height of the tile, the height of a raised center area, and the width of the tile's edges/walls.

2.  **Tile Types:** I need to be able to generate several types of tiles, including single tiles, pairs of tiles, rows of three, four, or five, triangle formations using three tiles, diamond formations using four tiles, and a block shape using six tiles, and a more complex cluster of 7 tiles surrounding a central tile. It should be possible to switch between these tile layouts easily using a parameter.

3.  **Interlocking Edges:** The edges of the tiles need to be designed to 'clip' together, so they interlock snugly when placed next to each other. These clips should be able to be optionally full-height or half-height. Each face of the hexagon should have an appropriate clip for joining with another tile.

4.  **Material Types:** I'd like to generate both "ground" tiles and "water" tiles, with water tiles having a slightly different overall height and no raised center area.

5.  **Texture:** For the ground tiles, I'd like an option to use a heightmap image file to generate a raised texture on the center face of the tile. If no file is specified, it should default to a blank raised hex center.

6.  **Supports:** The ground tiles should have an option to include minimal support structures on the underside to address bridging issues when 3D printed. These supports can just be simple geometric shapes that can easily be clipped off.

7. **Coloring:** The code should be able to apply a standard 'DarkGray' color to the output.

So, in summary, I need parametric control over:

*   Tile layout type (single, pair, row3, row4, row5, tri3, diam4, block6, rnd7)
*   Material type (ground or water)
*   Use heightmap texture (yes/no)
*   Heightmap file name
*   Include supports (yes/no)
*   The dimensions of the basic tile like edge width and height

I think that should cover it. I'd also prefer if the file were set up in a modular way; the tile design should be a separate module that's then called by the higher-level modules that arrange and connect the various hex types.

Could you generate the OpenSCAD files for this project? I don't think I need any special libraries for this, but let me know if I'm wrong.

Okay, I need a customizable hook designed in OpenSCAD. I've got some specific ideas about how it should work and the parameters that I need to control, but I'm not great at the code itself, so I'm hoping you can help.

The hook should be composed of three main sections: a top, a center, and a bottom. Both the top and bottom sections will have two curved portions each, an inner and outer curve, plus a straight bar. The center section is just a straight bar.

Here's a breakdown of the parameters I want to be able to tweak:

*   **Global:**
    *   `hook_thickness`: This is the extrusion height, and I'd like this to apply globally to the entire hook.
    *   `hook_width`: This should also apply to all parts of the hook, as the thickness of the material used to construct it.
*   **Top Section:**
    *   `top_inner_radius`: The radius of the inner curve at the top.
    *   `top_inner_angle`: The angle of that inner curve, in degrees.
    *   `top_outer_radius`: The radius of the outer curve at the top.
    *   `top_outer_angle`: The angle of the outer curve, in degrees.
    *   `top_length`: The length of the straight bar section at the top.
*   **Center Section:**
    *  `center_length`: The length of the center straight bar section.
*  **Bottom Section:**
    *   `bottom_inner_radius`: The radius of the inner curve at the bottom.
    *   `bottom_inner_angle`: The angle of the inner curve, in degrees.
    *  `bottom_outer_radius`: The radius of the outer curve at the bottom.
    *   `bottom_outer_angle`: The angle of the outer curve, in degrees.
    *   `bottom_length`: The length of the straight bar at the bottom.

I need to be able to adjust all of these parameters to create different hook shapes. The hook should be constructed with the assumption that the X axis is the width of the hook, and the Y axis is along the length, and the Z axis is the height, with the curves in the X/Y plane.  The origin should ideally be at the center of the center bar's width and height, and halfway along its length.

I'd like for you to use a "wedge" module, which I understand is a standard way to create curved shapes in OpenSCAD, rather than creating them using multiple small segments. I believe that module was originally by Alex English; you might have it in your library.

Could you generate the necessary OpenSCAD code based on these requirements? I am not attaching the code for that wedge module.

Okay, I need a parametric OpenSCAD design for a BNC dust cap, but with a twist on the bayonet slots. I've got a basic design already, but I need your help to make it parametric and more robust.

The main features should be:

*   **Cylindrical Body:** The cap should be a simple cylinder with an outer diameter and a height that can be adjusted. It should also have a hollow inner cylinder which can be a different, smaller diameter and will go over the BNC connector.

*   **Bayonet Slots:** Instead of just simple slots, I want the slots to have a small cavity or "pocket" at the end, kind of like a widened area, to securely hold the BNC connector's pins. Also, the slot itself should not be just a simple straight slot, but a curved path (kind of like a partial spiral) to engage the bayonet pins. The start of the slot should also be flat for a bit.

*   **Base:** The base should be a thin disk, slightly larger than the cylinder, attached to the bottom of the cylinder, which provides a larger surface to grab when removing or putting the cap on.

*   **Parameterization:** Everything should be easily customizable via parameters including:
    *   Inner diameter of the cap
    *   Inner height of the cap
    *   Wall thickness
    *   Outer diameter of the cap (which depends on the inner diameter and wall thickness, but should be adjustable as a final value)
    *   Slot offset (distance from inner cylinder to the start of the slot)
    *   Slot depth
    *   Slot width
    *   Depth of the pocket at the end of each bayonet slot
    *   Length of the flat start of the slot.
    *   Base height
    *   Base diameter

I also want some good comments in the code to make it clear what each parameter and module does. I think it'll need `hull()` and `rotate_extrude()` to make the curved slot but I'm not sure, I'm very much an amateur at this. It would be great if you use a small value for `$fn` to make sure that it renders quickly while I make changes, but maybe we can use a variable so I can easily make it higher when I finally export it for printing.

I'd also like the code organized into logical modules, so it's easy to see the different parts and their construction. I do not have any libraries to attach, please generate all the code for me from scratch. Also, please just use simple geometry functions and operations; I am not familiar with any fancy features.

Hey, I'm looking to generate a spiral staircase in OpenSCAD. I'd like to be able to control the number of revolutions, the radius of the staircase, the number of steps per revolution, the height of each step, and the radius of the central support column.

Ideally, the staircase would be constructed from individual, wedge-shaped steps arranged in a spiral around the column. Each step should be a slightly modified triangle. I would also like the steps to be colored differently, cycling through a rainbow palette (red, orange, yellow, green, blue, indigo, violet) as they rise. The central column should be a solid cylinder. I'm not looking to put railings on it yet.

Could you generate the OpenSCAD code for this? I'd like it to be a parametric design, so I can easily change all those settings. I'm not using any libraries at the moment, so everything should be self-contained.

Hi, I'm looking for a design for a journal pen holder that I can 3D print. I'd like it to clip onto the edge of a journal or book cover, not the spine. The pen holder should have an adjustable size to accommodate different cover thicknesses and pen diameters. It should also allow for adjusting the width of the holder, like, how far it sticks out from the cover. I’m envisioning a design where the pen slides into a C-shaped clip, and I’d like the option to increase the thickness at the tip of the clip to improve how well it holds the pen.

I want to be able to generate this using OpenSCAD.  I need a parametric design that allows me to set the following parameters:

*   **`Cover_thickness`**:  The thickness of the journal cover the holder will clip onto (say, a range of 1mm to 5mm).
*   **`Pen_diameter`**: The diameter of the pen the holder is designed for (say, a range of 5mm to 20mm).
*   **`Holder_width`**:  How far the holder sticks out from the edge of the journal (say, a range of 10mm to 30mm).
*  **`Retention_factor`**: A factor to increase the thickness at the tip of the pen clip to retain the pen (something like 0 to 0.5 should be fine).
*   **`Print`**: A boolean or flag that, if true, rotates the object into a position suitable for 3D printing. (maybe just 0 for no rotation, 1 for rotation).

I don't want to constrain the design to any specific look; I'm flexible on style as long as it's functional. Something similar to the attached OpenSCAD file should work, but I would like you to generate it from scratch. I've attached the existing `journal_pen_holder.scad` to show you the kind of functionality I'm looking for, but I want a clean design from the ground up.

I'd like a parametric OpenSCAD design for a Nintendo DS/3DS game cart holder, please. I'd like to be able to specify how many carts the holder should hold; either 1, 3, or 9.

For a single cart holder, it should be a rectangular block with a cutout for the game cart, plus clips to hold the game in place. The clips need to be slightly flexible, maybe with some thin sections. Also, it needs to have those little 'fingers' that hold the cart from below, not just the sides.

If I specify 3 carts, it should arrange 3 of these single cart holders in a row. And if I specify 9, it should be 3 rows of 3.

I'm not worried about fancy rounded corners for now.

Could you please use the BOSL2 library for this, if it makes sense for your design, or any other standard library that you might think helps. I'm not sure if any specific modules would be needed, I just like the structure of it.

Hey, I'm looking to get a parametric cable spool designed in OpenSCAD. I've seen a few examples online, but I need something that's flexible enough for different cable sizes and mounting needs.

Essentially, I need a two-part spool. One part (let's call it "Part A") has the main hub and a flange, and the other part ("Part B") is a second flange that connects to Part A. Part A needs a locating socket to fit Part B. Ideally, I want to be able to control all the critical dimensions:

*   **Flange Diameter:** The outer diameter of the spool's "flanges".
*   **Hub Diameter:** The outer diameter of the central core where the cable wraps around.
*   **Hub Inner Diameter:** The diameter of the hole through the center of the spool. This needs to be able to be customized to fit different mounting bars.
*   **Spool Width:** The total width of the spool.
*   **Flange Thickness:** The thickness of the flanges.
*   **Structure Thickness:** The thickness of the hub and web structures.
*   **Socket Depth:** The depth of the locating socket in Part B.
*   **Socket Clearance:** The radial clearance between the boss and socket (for ease of assembly).
*   **Cable Hole Diameter:** There needs to be a small hole through both flanges for starting or securing the cable.
*   **Number of Webs:** The number of support webs used in the hub and flange.
*   **Flange Web Thickness:** The thickness of the support webs in the flange, which are optionally used to cut out extra material.

I'd like to include an option to use cutouts in the flanges, using the webs, as well, to save material. So, a boolean variable for that would be great.

The design should use a central hole in both halves, and a boss on Part A that mates with the socket in Part B. These should be concentric with the hub.

Could you provide the OpenSCAD code for both Part A and Part B, or perhaps modules that generate each part separately?

Hi, I need a custom wall-mountable tube holder designed in OpenSCAD. It should be parametric so I can easily adjust it for different tube sizes and mounting requirements.

Here's what I'm looking for:

*   **Tube Holding:** It needs to securely hold a tube of a specified diameter.
*   **Adjustable Diameter:** The inner diameter where the tube sits should be a variable I can set.  Ideally, I'd like to be able to make it slightly smaller than the actual tube diameter for a tighter fit.
*   **Holder Height:** The height of the holder should also be adjustable.
*   **Wall Thickness:** I need to control the thickness of the material for strength and flexibility.
*   **Aperture Angle:** The opening for the tube should be angled, and I'd like to be able to adjust the angle to affect the ease of inserting and removing the tube.
*   **Mounting Holes:** There should be mounting holes to attach the holder to a wall. I'd like to specify the diameter of these holes. And it would be helpful if they had a countersink (or at least clearance) for the screw heads.
*   **Multiple Holders:** I need the option to create multiple holders in a single print, arranged in a row, with some spacing between them.
*   **No Support:** The design should be such that it doesn't need support material when printed, and should be easy to print even for a beginner with a 3D printer. I usually print in ABS, but sometimes PLA or PETG.

I've seen similar designs, and it's like a partial circle with an open angle and a couple of mounting points on a flat base. I'd prefer it if the main body of the holder was an arc cut from a cylinder to allow for adjustments in the angle and inner diameter, instead of some other more complicated shape.

I think it would make sense to have the basic structure be created from difference operations, so the initial cylinder is cut to create the arc, and then cut again to create the opening, and again to create the opening for the tube. Finally a support structure would be added. I think the screw holes should be generated from a union of two cylinders.

It would be really helpful to be able to adjust resolution so I can print faster with lower res or higher quality with higher res.

I'm not using any specific libraries so you should be able to generate all the necessary code yourself.

Thanks!

I'm looking to create a customizable hexagonal crayon/pen pot, and I'd like an OpenSCAD file that lets me control the size and shape of the overall structure.

Specifically, I envision a central hexagonal prism surrounded by six other hexagonal prisms attached to its faces, kind of like a flower. The central prism and each surrounding prism should be hollow, creating individual compartments. I'd like to be able to independently set the height of each of the 7 hexagonal prisms (central, NE, N, NW, SW, S, and SE). Also, I need to be able to control the radius of each hexagon and the wall thickness of the hollow prisms.

I'd like to define the following parameters:

*   `radius`: The radius of the hexagonal base.
*   `shell_thickness`: The thickness of the walls of each prism.
*   `central_hex_height`: The height of the central hexagonal prism.
*   `NE_hex_height`: The height of the hexagonal prism to the North East.
*   `N_hex_height`: The height of the hexagonal prism to the North.
*   `NW_hex_height`: The height of the hexagonal prism to the North West.
*   `SW_hex_height`: The height of the hexagonal prism to the South West.
*   `S_hex_height`: The height of the hexagonal prism to the South.
*   `SE_hex_height`: The height of the hexagonal prism to the South East.

I think the design could be built using basic `cylinder` primitives and `difference` operations. I don't think you'll need any external libraries for this. Could you generate an OpenSCAD file for me?
