I'd like to design a whirlycopter toy with a few different configurations, and I need some help getting the OpenSCAD files set up. I’ve been playing around with a modified version of seedwire’s ‘The Whirly One’ and it's given me a good idea of what I want, but I need to start fresh with a new design, and ideally, have it be much more configurable.

Here’s the basic idea: I want a central rotor with blades, and then I'd like to be able to swap out the mechanism that makes it spin. I'd like to be able to choose between three options: a simple handle (like a pinwheel), a string pull mechanism, and a spin stick.

First, the rotor itself. The blades should have a configurable radius, width, thickness, and pitch angle. I'd like the option to have rounded ends on the blades as well. If the blades don't have rounded ends, I want an outer ring to be automatically generated for safety. There should also be a variable for the number of blades on the rotor. The entire rotor assembly should have a consistent height.

For the handle configuration, it should be a simple cylinder extending from the center of the rotor. The length of the handle should be configurable.

The string pull option will need a hand block with a hole for the string and a slot for the rotor to fit into and spin. The design should be fairly robust. I have a rough idea of the general shape. I’m okay with the general design of the existing model, though I'm open to other ideas that are more printable.

Finally, for the spin stick, I’d like a spiral stick with a rectangular cross-section that the rotor can slide along. The twist rate of the spiral needs to be adjustable. There will also need a handle at the end that has a larger rectangular profile. I also need a pusher piece, which is a small piece with a hole that matches the profile of the spiral and a brim that makes it easier to push.

I’d like to use a `material_gap` parameter to control the tolerance between moving parts and a `slider_thickness` for the pusher walls.

The overall goal is to have an OpenSCAD setup where I can easily swap between these three mechanisms by setting a config parameter, and then it would generate the appropriate parts.

I think that covers most of it. I am not familiar with how best to organize this into libraries so could you please make all of the files needed to create these objects, without using any pre-existing libraries. I can always split them apart later. Thanks!

//  The Whirly with Spin Stick
//  based on:
//
// The Whirly One
//  by seedwire (see Below)
//
//  Adapted by cstelter to add spin stick system
//
//  Note, I have not tried printing the string thing nor the handle
//  after my rework-- I was primarily trying to make the spin stick, but
//  after I was reasonably successful with that, I tried to fix up the file
//  again so that it could still do what it was originally designed to do.
//
//  I changed quite a bit of the math for the blade pitch and offsets.  My
//  main concern is that the default value of 5mm for the 'handle'
//  when building the string spinner may not be the best value for use in the
//  string spinner.

Okay, I'm looking to create a customizable filament filter for my 3D printer, and I want it to include an integrated clip to attach to the spool. I've seen a few designs online, but I'd really like to be able to tweak all the parameters to fit my needs perfectly.

Here's the breakdown of what I need:

**Core Filter Design:**

*   **Shape:** It should be a cylindrical filter with rounded or flat caps at both ends. The choice of round or flat caps should be a parameter.
*   **Internal Structure:** The filter needs an inner cylindrical space where the filament passes through. The top and bottom of this space will taper inwards to the exit hole and this transition to the inner cylinder needs to be parametric.
*   **Exit Hole:** There should be a central hole for the filament to exit. The diameter needs to be adjustable.
*   **Filament Entry Slot:** There needs to be a slot cut into the side to capture the filament. This slot should be angled, specifically 45 degrees, to better handle 3mm filament, and the slot size relative to the filament diameter should also be adjustable. I need to be able to specify how much smaller the slot should be than the filament diameter using a slot_factor, where 6 is normal, 2 is thinner, and 8 is slight.
*   **Parameters:** I need to control these main dimensions:
    *   Overall filter height
    *   Overall filter width
    *   Exit hole diameter
    *   Filament diameter (for the slot)
    *   Slot factor (how much thinner the slot is than the filament hole)
    *   Choice of round or flat base
*   **Visualization:** I want to include an option to show a cross-section of the filter, cutting it in half to make the internal structure clear.

**Integrated Clip Design:**

*   **Function:** The clip should be designed to securely attach the filter to the edge of a filament spool.
*   **Shape:** It should be an open C shape that can flex to clip onto the spool.
*   **Integration:** This clip needs to be attached to the side of the cylindrical filter.
*   **Parameters:** I need to be able to enable/disable the clip, and specify a minimum length for the clip. The actual length should be the minimum of this parameter and the height of the filter.

**General Requirements:**

*   **Customization:** I need to be able to adjust all the dimensions described above.
*   **OpenSCAD:** I'd like the code to be in OpenSCAD, and I'd like it to be parametric and use modules where appropriate to make it clean and maintainable. I'd like to use the `min()` function where appropriate.
*   **No Support Required:** The filter should be designed to print without support, both with round and flat bases.
*   **Libraries:** I don't believe I need any additional external libraries for this, I think it can be done with core OpenSCAD functionality.

I've tried to be as thorough as possible in my request so that I can create a highly functional part that fits my 3d printing needs. Let me know if you need any further clarifications.

Hi! I'm trying to design a model of an Abloy Classic key and its cylinder for 3D printing, mainly as an educational tool. I want to be able to customize it to demonstrate how the key's cuts interact with the rotating discs in the lock.

Here's what I'm thinking:

**Key:**

*   The key should be a cylinder with a series of angled cuts along its length.
*   I need to be able to control the depth and angle of each cut.
*   The number of cuts should be adjustable, based on the key code.
*   I'd like a handle, that's optional (I have this as a binary variable in my code).
*   The key body length and diameter should be configurable.
*   I'd like a parameter for cut spacing, as well as cut angle increment (I use 18 degrees in my code)
*   I'd like a way to highlight the body, cuts, and handle individually for preview purposes. I'm doing this now using a module and "preview\_tab" variable, if that's helpful.
*   For now, I just want a simple cylinder handle, but might want to do something a bit fancier later on.

**Lock Cylinder:**

*   The cylinder should have a matching number of rotating discs that correspond with the cuts in the key.
*   I need to control the diameter and depth of the discs, and the overall length of the cylinder.
*   The cylinder should have a space for the key to fit in, obviously.
*   I'd like to be able to highlight the discs, the cylinder body, and the keyway individually.
*   The discs should have a small peg on them that will be positioned by the key cuts.
*   The peg will also be used to show which disc is which and what part of the key interacts with which disc.
*   I'd like the pegs to be a separate color from the discs for clarity.

I'm thinking it'd be best to use a parametric approach, so I can easily modify the key code, size, number of discs, etc., without a lot of manual changes.  I'm okay if the discs are just "floating" in their space - I'm not looking for a fully detailed internal mechanism at this point.

For OpenSCAD, I’m comfortable with basic modules, loops, and transformations. I'm also familiar with the `color()` command.

Could you help me create the necessary OpenSCAD code for this project? I imagine this would need to be broken into at least two files, one for the key and one for the lock cylinder. I think we can start with the basics and add more complexity later if needed. I'm not using any specific libraries, so everything would have to be made from scratch.

I'd like a carry handle designed for a Prusa i3 Pro Steel 3D printer. I've seen some online, but I'd like to have a parametric design so I can tweak it if needed.

Here are the general specifications:

The handle attaches to the printer frame using triangular cutouts that match the frame's structure. The horizontal side of these triangles is 26.5mm. The distance between the corners of two adjacent triangles (over 2 triangles) is 58.5mm. These measurements are what I took on my frame, so the design should include a small tolerance to accommodate slight variations. Let's add a 0.2mm tolerance. The triangles should also have rounded corners, with a radius of 2mm. The printer frame itself is 3mm thick and the width is 50mm and length is 120mm, which we will also want to use in the design.

The handle should have a finger grab area that's 100mm wide and 30mm high with a backplate that's 7mm thick. Both the finger grab area and the backplate should have rounded edges. The finger grab should have a rounding radius of 5mm and the finger grab itself should have a radius of 10mm. The handle should also have holes for guiding filament. These holes should be positioned a distance of 42.5mm apart and have a diameter of 3.2mm. I need them to go all the way through the back plate. I'd also like to have some countersunk areas for screw heads, these should be about 0.8 times the diameter of the holes themselves, and go about half of the depth of the back plate.

The filament guides should have a bore of 6mm with the filament itself having a diameter of 3.1mm. The filament guides should be offset from the edge by 7.5mm.

To make everything look clean, I need a way to adjust the rounding on the backplate, moving it towards the finger grab. Let's call this `roundoffset` and have it default to 3.3mm. I also want to be able to shift the finger grab lower and closer to the frame; I'd like to call that `handleoffset`, with a default of 2.8mm. Finally, add a `frameextend` parameter to increase the frame height - 2.8mm should be a good default value for it.

I think this is all the dimensions I need, the design should be in OpenSCAD and be completely parametric.

I'd like to get an OpenSCAD design for a customizable spool holder. The basic idea is to have a clip that attaches to a frame, and a rod that holds the spool.

The key parameters I want to be able to adjust are:

*   **thickness:**  The thickness of the frame the clip attaches to (default is 7mm).
*   **depth:**  The total depth of the clip, which will also relate to how far the spool sits from the frame (default is thickness + 8 mm, so 15mm)
*   **width:** The width of the clip (default 10mm).
*   **frame:**  The length of the clip that grabs the frame, measured along the frame (default is 21mm).
*   **diameter:**  The diameter of the spool, which will be used to help determine the arm holding the rod that holds the spool. (default is 150mm).
*   **rod:** The diameter of the rod the spool sits on (default is 5mm).

The holder will essentially be a rectangular block with a clip to attach to the frame, a diagonal arm extending from this rectangular block, and a rod at the end of this arm that the spool will sit on.  The diagonal arm should start roughly from one corner of the block, and be at a 45 degree angle.

The holder should use difference() operations to remove the material for the clip, the spool holder, and the hole in the arm for the rod.

I'm not too picky about libraries, but if you think any of the usual ones would make this easier, feel free to use them. I'd prefer not to use non-standard or experimental libraries.

I'm looking for an OpenSCAD design for a wall-mounted phone holder, and I'd like it to be parametric so I can easily customize it later. I've got some specific ideas about the shape and features.

Here's the basic idea:

*   **Phone Holding Area:** The main feature is a circular cutout for the phone to rest in. Think of it like a shallow cylinder that's been flattened a bit on the back side. The cylinder will be cut in half by a rectangular prism
    *   I want to be able to adjust the radius of the hole.
    *   I want to be able to adjust how "squashed" the circle is on the back, as a ratio between 0 and 1.
    *  I want to adjust the thickness of the main cylinder.
*   **Base:** This main hole is going to be attached to a rectangular base.
    *   The base should be a specified distance away from the hole
    *   I want to be able to adjust both the width and height of this base.
    *   The base will be connected to the cylinder by a hull.
*   **Reinforcement:** I also need a triangular reinforcement connecting the base to the main body to support its weight.
    *   I want to be able to adjust the angle of the support.
    *   I need to be able to adjust the thickness of the support.
*   **Text:** I'd like to add some text to the front of the holder, near the base.
    *   This text needs to be customizable.
    *   I need to be able to adjust the size of the text.

Could you generate an OpenSCAD file for this design with all of these parameters? I want to make it very customizable. I don't need to print this today, so don't worry about optimizing it for printing exactly, but do keep in mind that I am planning on printing this so don't go overboard on features that will break the print. I think the basic OpenSCAD library is sufficient. Thanks!

Hey, I'm trying to design a cool 3D model using OpenSCAD, and I need some help making it parametric. I'm going for a cube with a spherical hole through the center and a sphere sitting on top, connected by a small cylinder. I've got some basic code, but it's not very flexible.

Here's what I'm looking for:

1.  A cube with adjustable size. I want to be able to control its dimensions easily.
2.  A perfect sphere cut out of the center of the cube, and its radius should be adjustable.
3.  A second sphere sitting on top of the cube, which I want to be able to scale.
4.  A small cylinder connecting the top sphere to the cube, which should also have its parameters configurable.
5.  The whole thing should be nicely centered on the origin.
6. I'd like for there to be easily accessible variables, so that I can adjust the whole shape very easily.

I'm basically trying to make a fancy display stand for the upper sphere inside the cube, and want to adjust the proportions of the various components as I see fit.

I'm not using any libraries at the moment, but if you recommend something to make this easier that would be welcome.

I'd like to create a customizable star shape in OpenSCAD, building on the basic design I already have. I've got this base file that makes a star by combining cubes, but it's not very flexible.

My current code is:

```
size=30;

union()	{
cube(size-5, true);
rotate([45,0,0]) cube(size, true);
rotate([0,45,0]) cube(size, true);
rotate([0,0,45]) cube(size, true);

}
```

What I'm looking for is a version where I can easily control several aspects of the star:

1.  **Overall Size:** I'd like a parameter that controls the overall size of the star. This would essentially scale everything up or down.
2.  **Core Size:** The central cube is currently hardcoded as `size - 5`. I want this to be controlled with a separate parameter that determines its size relative to the overall size. For instance, a core_size of 0.5 would mean the core is half the size of the overall star size.
3.  **Arm Thickness:** The cubes rotated to form the arms are currently all the same thickness as their length. I want a parameter to make these arms thinner or thicker while keeping their lengths derived from the overall size.  I'd like this to be relative to the overall size as well. A value of 1 would be the same thickness, 0.5 would mean the arms are half the thickness relative to the star size, etc.
4.  **Rotation Angles:** I'd also want to control the rotation angles, not fixed at 45 degrees. Each axis rotation should have its own parameter (e.g., `rotate_x`, `rotate_y`, `rotate_z`).

I'd prefer that the core of the star always remains centered in the output. It looks like you were already making sure the cubes were centered, so please keep doing that. I'd also want the arm cubes to start from the center of the core, which I *think* my code already does. I'm not really expecting to change that.

Could you please generate an OpenSCAD file that incorporates these parameters? I don't need any library dependencies. Just a single .scad file with all the functionality I described, please!

I'm looking to create a cable wrap, something that helps organize and prevent cables from tangling. I've got a basic design in mind, kind of like a flattened tube with a slit in it to insert the cables. I'd like the OpenSCAD code to be parametric so I can easily adjust the dimensions.

Here's what I'm envisioning:

*   **Overall Shape:** A rectangular base with rounded ends, forming the basic tube shape.
*   **Height (h):** This would be the height of the extrusion, essentially the thickness of the wrap. I want this to be a configurable parameter.
*   **Width (b):**  The width of the rectangular portion before the rounding - also a parameter I would like to be able to control.
*   **Length (l):** The overall length of the wrap.
*   **Cable Gap (f):** A slit running down the length of the wrap where the cables go in, this needs to be a parameter as well.
*   **Inner Tube:** The actual cable channel needs to be hollowed out. I'd like this to be a cylindrical void with a flat section for the cable entry slit on one side.

Essentially, I need two main parts: The main wrap shape, which should be an extruded rounded rectangle, and a second shape to cut out the inner tube. I'd like to have the slit cut out of the hollowed inner tube. I think the code will need to use the `linear_extrude` function, and likely need a `difference()` to create the hollow. I also need to define a few variables at the start for all of my parameters (h, b, l, and f).

Could you please create a parametric OpenSCAD file for this? I don't need any external libraries for this simple design.

Hey, I'm looking to get a design made for a sort of spaceship/flying wing thing in OpenSCAD. I've got a basic idea of the shape I want, which I've described in a single existing SCAD file, but I'd like to have it fully parameterized so I can easily tweak the dimensions.

Essentially, the design consists of three main parts: two mirrored "back wings," a central platform, and a cockpit on top.

**Back Wings:** Each back wing is created by extruding a polygon shape and then subtracting a cube to achieve the final form. The polygon shape is defined by three points and the extrusion height is fixed, and there is a rotation and translation applied as well. It would be nice to control the angle of rotation (currently -5 degrees around x) as well as translation and the three points of the defining polygon. I think it should be possible to derive the points for the wing from the wing_span, but I'd like to be able to control all three points directly if needed.

**Central Platform:** This is a simple extruded polygon. There are 4 points, forming a trapezoid. I'd like to be able to specify each of the four points individually, but I'd also like it to be convenient to have it calculated from the base_width and base_length parameters and an extrusion height, as shown in my basic version.

**Cockpit:** The cockpit is a simple tetrahedron, created from a polyhedron. The base of the tetrahedron is a square and then there is a single apex point. The base of the cockpit is currently offset along y. I'd like to be able to adjust all 4 of the base points, or to specify the base of the cockpit as a square with side length, and be able to specify the z coordinate of the apex (cockpit_height). It'd be great if I could also control the offset.

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

*   `wing_span`: (affects the overall width of each wing, but each point of the back_wing should be controllable.)
*   `cockpit_height`: (z-coordinate of cockpit apex.)
*   `base_width`: (width of base platform)
*   `base_length`: (length of base platform)
*   rotation for the back wings (angle around x)
*   translation for back wings.
*   the four points of the central platform (or base_width, base_length, and offset if that's easier).
*   the four points of the base of the cockpit (or a center and side length).
*   the offset of the cockpit from the platform

I'd like all of these to be parameterized and easily adjustable. It'd also be nice to include some comments in the code to make it clear what each parameter controls. I'm not using any external libraries, so this should be all basic OpenSCAD.

Could you help me generate the necessary parametric OpenSCAD files?

Hey, I'm working on a little project to help my daughter understand friction, and I think it would be great if I could have a parametric OpenSCAD model for it.

Basically, I want to create a block with a series of triangular teeth along one of its faces. These teeth are what will affect how easily other objects slide along the surface, so I want to be able to easily change their size and number.

Specifically, I need a model with these parameters:

*   `base_length`: The length of the main block.
*   `base_width`: The width of the main block.
*   `base_height`: The height of the main block.
*   `teeth_height`: The height of each triangular tooth.
*   `num_teeth`: The number of teeth along the length of the block.

The teeth should be isosceles triangles, and they should all be the same size, evenly spaced along one of the long sides of the block. The teeth should be perpendicular to the block's face, pointing away from the block.

I want to be able to change all of the parameters in the file and see the model update accordingly. If you could generate the necessary OpenSCAD code, that would be awesome. I don't think I need any special libraries for this one, but if you think they would make it easier or better, I'm open to suggestions. Thanks a lot!

Hey, I'm looking for an OpenSCAD design for a customizable pipe clamp, similar to one I found online but I'd like it from scratch. It should have a hinged design so it can open and close easily, and the dimensions need to be easily adjustable. The basic idea is to have a circular clamp that wraps around the pipe, with a hinge on one side and some kind of connector on the other to hold it closed.

Here are the parameters I'd like to be able to control:

*   `r1`: The radius of the pipe the clamp is meant for.
*   `h`: The width or thickness of the clamp.
*   `s`: The strength of the clamp; essentially, how thick the clamp material is, affecting its overall strength.
*   `r4`: The radius of the screw holes used for the connector.
*   `con`:  A parameter to choose the type of connector. `0` would be no connector (just the hinge), `1` would be a simple hole for a bolt or pin, and `2` would be a cube-shaped latch with a hole for a bolt or pin.

I think it would be helpful to also define these internal variables (that aren't user parameters):

*   `r2`: `r1 + s`  (the outer radius of the clamp)
*   `w`: a fixed width of 14 for the clamp parts
*   `r3`: a fixed radius of 8 for hinge pins
*   `th`: a fixed thickness of 5 for the connector pieces

The clamp itself should be made from two half-circular pieces with a hinge on one side, and the selected connector type on the other side. The hinge should use two cylindrical pins and be located on one edge. The connector is what the two halves use to clamp together. The different `con` values affect that connector in the following way: If `con` is 0 then no connector is modeled. If `con` is 1 then there should be two small holes, one through the width and the other through the clamp to the center of the pipe. If `con` is 2 then there should be a small cube with a hole in it for the second connector to slot into.

I don't have a strong preference about libraries, but if it makes it easier you could use one of the standard ones. For example, MCAD, BOSL, BOSL2, dotSCAD, NopSCADlib, or BOLTS would all be acceptable.

I'd like the ability to adjust the number of facets of the circles using `$fn`, and I'm thinking `$fn=50` would be good for a default.

I'm looking to create a set of customizable connectors for various projects, like mounting a bike accessory, building a flexible tablet arm, or even a webcam holder. The idea is to have a basic connector piece that can be screwed together with other similar pieces to allow for adjustable angles in multiple directions.

I have a starting point in mind, which I'll describe. The core connector piece should be a rectangular block with a specific length, width, and height. It needs two screw holes: one on the side and another one either on the top or the side, controlled by a parameter. These holes should be equally spaced from the edges. The end of the connector should be rounded on both sides. Also, I'd like to add a cap module that is used to tighten the screws.

Here are the specific parameters I want to be able to control:

*   **Overall length (l)**: The total length of the connector.
*   **Width (wid)**: The width of the connector. Should have a minimum value of 10 and a maximum of 50.
*   **Screw hole radius (r1)**: The radius of the screw holes. Should range from 1.5 to 6 in steps of 0.5.
*   **Hole direction (hole)**: A parameter to switch between the second screw hole being vertical (0) or horizontal (1)
*   **Height (h):** The height of the connector, which should equal the width (wid).

The basic shape should be a rectangular prism, with a couple of cylindrical screw holes. If `hole` is 0, then the first screw hole is centered on the side, and the second screw hole is centered on the top. If `hole` is 1, then both holes are centered on their respective sides. The ends of the connector should be rounded on both sides, and a little extra material should extend on both sides of the width dimension.

Additionally, I need a separate cap module. It should consist of a main cylinder, which has a wider cylinder in its mid section, a cube, and a rotated cube to provide some finger grips, and a smaller cylinder inside which represents the threaded area to tighten the bolts.

So, I'd need a main connector module and the cap module. Could you create these as parametric modules in OpenSCAD?

I'd like to design a parametric cable organizer, kind of like the one I've already got, but I'd like to be able to customize it more easily. The basic idea is that it's made of several rings arranged in a circle, each with a cutout for a cable. I’d like to be able to specify the number of rings, the radius of the overall circle that those rings are arranged into, the height of the organizer, and the thickness of the rings themselves.

The rings will be positioned around a central axis, equally spaced, and will be rotated so that each cutout faces outwards from the central circle. I also want to define the overall radius of the ring that the cable goes into, not the radius of the cylinder that is used to arrange them in a circle.

It’d be great if this could be done as a parametric OpenSCAD file, so I can easily tweak those values and generate different versions. The existing file I have is attached (ver2.0.scad), but I'd prefer it if you didn't build upon that directly and started from scratch instead. I would also like to keep it as a single file.

Okay, I want to design a customizable ring with some text embossed on the outside. I've got some ideas about how I'd like it to work, but I'm not very good at OpenSCAD.

First off, the ring itself should be a simple cylinder with a hole in it, so it can actually fit on a finger. I need to be able to set the outer radius (`r1`) of the ring, its height/thickness (`d`), and also the radius of the hole (`r1 - 5` like it is currently). I'd like to have a variable for the inner radius to make it easier in the future (`r2`).

Then, I want to emboss text on the outside of the ring. The text should be a variable, `text`, that I can set. I also want to set the font size (`size`) and the height that the text is raised from the ring surface (`h2`). The text should be centered around the circumference of the ring. There should also be an option to change the color of the text (`x,y,z`). I need to be able to also set the color of the ring (`a,b,c`).

I'd like to add a convexity to the embossed text, like how `linear_extrude` has a `convexity` parameter. This is already in the current code I have, as parameter `c`.

I need to use the `write/Write.scad` library so I can use the text function in the file. I'd like all the relevant variables to have reasonable limits and be easily set in the customizer.

Let me know what you think. I'm looking forward to seeing the results!

Hi! I'm looking to design a custom cup sleeve, and I'd like some help creating an OpenSCAD file.

Essentially, I want a sleeve that fits around a tapered cup. The cup itself has a defined top diameter, bottom diameter, and height, and I want to be able to adjust these parameters. The sleeve should have a configurable height, thickness, and pattern. I'd like to control whether the pattern is circular or square, and I want it to be randomly generated within constraints that I specify. Finally, I want to be able to add custom text that wraps around the sleeve.

Specifically, here are the parameters I need:

*   **Cup Dimensions:**
    *   `diameter_top`: Diameter of the cup at the top.
    *   `diameter_bottom`: Diameter of the cup at the bottom.
    *   `cup_height`: Height of the cup.
*   **Sleeve Dimensions:**
    *   `sleeve_type`: Integer to choose between circular or square patterns (e.g. 0 for circle, 1 for square).
    *  `sleeve_thickness`: Thickness of the sleeve.
    *   `sleeve_height`: Height of the sleeve.
*   **Text Parameters:**
    *   `name`: Text to be displayed on the sleeve.
    *   `text_size`: Size of the text.
* **Hidden Parameters**
     *  `cup_shell`: Shell thickness of the cup for making it hollow (if I choose to render the cup)
     * `res`: Resolution of the cylinder object

The sleeve itself should follow the taper of the cup, and I'd like it to be slightly larger than the cup so it fits comfortably. For the text, I'd like it to wrap around the sleeve and be placed roughly in the center of the sleeve's height.

For the random patterns, if `sleeve_type` is 0, they should be circular cutouts, generated randomly in size and placement. If `sleeve_type` is 1, they should be square cutouts, again random size and placement.

Could you create an OpenSCAD file that will allow me to adjust all of these parameters, and that will also generate a sleeve with the specified characteristics? I'd like to be able to render the cup itself if I wanted to, but that's not required for the final sleeve to work. I don't have any existing code to provide you, so please generate everything from scratch. I don't need to worry about any external libraries.

Hi, I'm looking to create a parametric LED holder for an engraved glass plate, and I'd like some help designing the OpenSCAD files. I've got a basic concept in mind but need it fleshed out and made customizable.

Essentially, the holder should grip a rectangular glass plate along its long edges and have evenly spaced LEDs along that edge to illuminate it. The design should also include a support structure at the back of the holder.

Here are the specific parameters I need to control:

*   **`length`**: The length of the glass plate (and the overall length of the holder).
*   **`led_size`**: The diameter of the LEDs.
*   **`led_height`**: The height of the LEDs.
*   **`length_support`**: The length of the back support structure extending out from the holder.
*   **`glass_thickness`**: The thickness of the glass plate being held.
*  **`glass_holder_height`**: The extra height of the holder structure on the side of the glass.
*   **`angle`**: The backwards angle (in degrees) of the entire holder.
*  **`nol`**: The number of LEDs to be used along the holder.

The holder should have a channel to insert the glass. I also need some support at the edges, extending back from the main channel. Finally, I'd like some holes, or channels for wires.

Ideally, the design should be adaptable so that these variables can be adjusted easily and the model will update accordingly.

I would prefer you generate a parametric OpenSCAD model from scratch rather than modifying something I have already made. Could you generate the necessary .scad files? I'm not currently using any external libraries (MCAD, BOSL, etc), so please don't include dependencies on any.

//Thickness of the glass (insert size)
glass_thickness = 2.6;

//Extra height on the side
glass_holder_height = 6;

//The angle (backwards) of the holder

I'm looking to design a headpiece for a little girl, something kind of whimsical and fun. I have a basic idea in mind, but need some help getting it into OpenSCAD.

The core design is based on two elements: a green, curved band and a ring of yellow stars.

The band should be a smooth, curved shape, kind of like a half-circle that's been extruded into a 3D form, and should have some thickness. I'd like the extrusion to be created by rotating a scaled circle, and I'd like to control the overall radius of the circular shape and the scale factors for scaling the circle before rotating it. I'm thinking that the thickness should be controlled by the scale in the Y-direction. I think rotating on the Z-axis will work.

The stars should be arranged in a circular ring around the band, and I'd like the number of stars and the radius of that ring to be configurable. The stars themselves should be pointy with variable sized points. I'd also like to be able to control the rotation of the entire star ring, and also the rotation of each individual star as it's placed. I have a basic idea of how to make the star, but it would be nice if it could take an array of radii for each point, so they're not all the same.

I'd like all of this to be fully parametric so I can easily adjust the sizing, number of stars, and the specific star shapes. So ideally I should be able to specify the circle radius, the scaling factor for the band extrusion, the number of stars, the radius of the ring they're on, the array of radii for the star points, the overall rotation of the star ring, and the rotation of each star individually as they're added to the ring.

It'd be amazing if you could generate an OpenSCAD file for me that does all of this! I'm not using any libraries (e.g., MCAD, BOSL, etc.) and would like to keep the solution using just standard OpenSCAD commands.

I need a parametric OpenSCAD design for a tube collar. I'm going to describe what I'm looking for and the parameters I need to be able to control.

The basic shape is a cylinder with a wider flange at one end. The inner cylinder should have a customizable diameter, which I'll call `inner_diameter`, that will be the inside diameter that fits over the tube. The main body will have a customizable overall height called `total_height`. There should also be a flange on one end, with a height called `flange_height` and a width called `flange_width`. The outer diameter will be calculated from the inner diameter and flange width.

I need to be able to specify all of these dimensions in tens of millimeters, so `inner_diameter=254` means 2540 mm.

In short, I need these parameters exposed in the customizer:

*   `inner_diameter`:  The inner diameter of the collar, in tens of mm.
*   `outer_diameter`: The outer diameter of the main body of the collar, in tens of mm
*   `total_height`: The total height of the collar, in tens of mm.
*   `flange_height`: The height of the flange, in tens of mm.
*   `flange_width`: The width of the flange, in tens of mm.

The design needs to use the `difference()` function to create a hollow cylinder and flange, then subtract a cube from it to ensure that there is nothing on one side of the inner cylinder. The cube should be positioned such that it extends from the bottom of the object upwards, and far enough to the sides that it cuts out a large chunk of the cylinder. It should also be wider than the outer diameter of the flange. Make sure to account for the difference in scale, dividing by 10 where appropriate to get mm for rendering.
