I'm looking to create a design similar to a Tai Chi symbol, but as a 3D printable disc. The basic idea is a circular disc with a curved dividing line like the yin-yang symbol. I'd like to be able to control the outer diameter of the disc, the width of the "line" or dividing curve, and the overall thickness of the disc.

Ideally, I'd like the design to be parametric using OpenSCAD, so I can easily adjust the dimensions. I need a function or module that takes at least the outer diameter, the line width (thickness) of the dividing curve, and the total thickness of the disc as parameters. So, for example, I could call something like `taichi_disc(diameter=50, line_width=5, thickness=8)` to get a disc with a 50mm diameter, a 5mm wide dividing curve, and 8mm thickness.

The dividing curve should be created by two overlapping semi-circular shapes, as described in my existing code.

I don't need any additional features, just a simple disc with the yin yang style division.

I need a parametric OpenSCAD design for a cable clip that attaches to a pole. Here are the requirements:

**Basic Structure:**

*   The clip should wrap partially around a pole and hold a cable.
*   It should be printable without supports.
*   It should be designed so it can be printed in a way that the clip part is not being printed over air, which would be bad.
*   The clip part should be perpendicular to the pole surface

**Parameters (all in mm):**

*   `pole_dia`: Diameter of the pole.
*   `pole_thick`: Thickness of material around the pole (the material that *hugs* the pole).
*   `pole_h`: Height/thickness of the printed part.
*   `clip_thick`: Thickness of the clip itself.
*   `clip_depth`: Depth/length of the clip (how far it sticks out from the pole).

**Specific Details:**

*   The clip part should extend out from the pole and wrap back in, forming a "U" shape, if you view it from the top down (it's a 'C' if you view it from the side).
*   The clip should not completely encircle the pole; it needs to be a "C" shape which can be slid onto the pole from the side, the ends of the "C" should not quite meet.
*   The design should use smooth curves for the part that hugs the pole.

**Desired Output:**

*   A single `.scad` file with all the parameters defined at the top.
*   The file should render as a single part (no need for separate pieces).

I'm hoping this is clear enough. Let me know if you have any questions. I'm not expecting the model to be absolutely perfect on the first try, but it should get the general idea of the design. I do not expect you to be able to use any other files than the single .scad file that you create.

Hey, I'm looking for a parametric OpenSCAD design for a spool bushing. I have a basic design in mind, which I'll describe, but I'd like it to be fully customizable using parameters.

Essentially, it's a cylindrical spacer that goes on either side of a spool to help it rotate smoothly on a rod. The main body is a cylinder with a smaller cylinder cut out to create the hole for the rod, and it also includes a backplate. There are tabs to prevent the spool from sliding back and forth.

Here are the key dimensions and features I'm thinking of, and I want all of these to be configurable parameters:

*   **`SpoolSize`**: The outer diameter of the main cylindrical part of the bushing, which sits flush with the spool.
*   **`TabThickness`**: The thickness of each tab.
*   **`BackplateRim`**: The distance from the outer edge of the main cylinder to the outer edge of the backplate.
*   **`BackplateThickness`**: The thickness of the backplate.
*    **`TabGap`**: The width of the space between the tabs.
*   **`TabDepth`**: The depth or height of the tabs.
*   **`SpoolRodSize`**: The inner diameter of the bushing - that's the hole that the rod goes through.
*   **`Tolerance`**: A small tolerance value that will be used in various parts of the design to ensure parts fit properly. This should be added to the inner diameter, and subtracted from the backplate outer diameter.
*   **`TabSize`**: This should be derived from `TabThickness * 2`, and represent the width of each tab. I'd prefer to see a comment that this is defined as such, and not an exposed parameter.

Here's how I'm imagining the parts to be assembled:

1.  First, create the base cylinder with a height of `1.5`, an outer diameter of `SpoolSize + BackplateRim - Tolerance` and then subtract a cylinder of height `1.5`, and diameter `SpoolRodSize + Tolerance`. This creates a flat washer.
2.  Next, translate the origin up 1.5, and create the main body: a cylinder of height `TabDepth` and diameter `SpoolSize`. Then cut out the inner part of the main cylinder using a cylinder with the same height and a diameter of `SpoolSize - TabSize`.
3.  Add the tabs to the main cylinder by subtracting two cubes. One cube should run along the diameter of the main cylinder, centered on the X axis, and the other along the Y axis, also centered. These should extend through the main cylinder, so that the final object has gaps where the tabs should be.

I would like it to be a single .scad file using standard OpenSCAD primitives. I'm not using any special libraries for this. Thanks!

Hey, I'm looking to design a battery mount for a ZMR250 quadcopter. I've got some existing code that provides a basic framework, but I need a fully parametric solution that's easier to customize. I'm using OpenSCAD, and I'd like to use modules and parameters to adjust most dimensions so that the battery mount will work with many different batteries and frames, instead of being designed for a single battery and frame.

Here's what I need:

**General Requirements:**

*   The design should mount flush with the top plate of the ZMR250 frame directly behind the standard camera mount, similar to the current implementation.
*   It should use two screws that pass through the top plate to secure the mount.
*   The main body of the mount should act as a cradle for the battery, holding it in place.
*   I'd like to have an optional strap tab on the back for securing a battery strap. This should be controllable by a parameter.
*   The design should be able to handle various battery heights, widths and lengths, and we should be able to specify the acceptable frame width at the front and the back of the mount, as well.
*   I'd like to try and reduce the overall amount of material used, ideally by hollowing out some of the internal material without compromising the strength of the mount.
*   I would also like to be able to control the tolerances used in the design; for example, I would want to be able to use a parameter to control how much extra room is given for the battery in the height, width, and length directions.

**Parameters:**

*   `battery_length`: Length of the battery.
*   `battery_width`: Width of the battery.
*   `battery_height`: Height of the battery.
*   `battery_tolerance`: A general tolerance value (in millimeters) for the battery cradle (height, width, and length, all using this value).
*   `frame_width_front`: Maximum width of the frame at the front of the mount.
*   `frame_width_rear`: Minimum width of the frame at the rear of the mount.
*   `mount_length`: the length of the base mount
*   `screw_hole_distance`: Distance between screw holes on the top plate.
*   `screw_hole_radius`: Radius of the screw holes.
*   `screw_head_radius`: Radius of the screw head.
*   `screw_head_height`: Height of the screw head.
*   `strap_tab_enabled`: Boolean parameter (true/false or "Yes"/"No") to enable/disable the strap tab.
*    `strap_tab_width`: width of the strap tab
*    `strap_tab_depth`: depth of the strap tab
*    `strap_tab_height`: height of the strap tab
*   `wall_thickness`: Thickness of the walls of the mount.
*   `base_thickness`: Thickness of the base of the mount where it connects to the frame.

**Modules:**

*   `battery_mount()`: Main module to generate the complete battery mount. This module will call the other modules.
*    `base_mount()`: Module to generate the base shape of the mount, accounting for frame width.
*   `battery_cradle()`: Module to generate the battery cradle, using the input dimensions and tolerances.
*   `screw_holes()`: Module to generate the screw holes using the screw_hole distance, radii and the thickness of the base of the mount.
*   `strap_tab()`: Module to generate the optional strap tab.
*   `cutouts()`: Module to subtract away the internal material to reduce weight

**Libraries:**

*   I don't need any external libraries for this project.

I'd like to see a single OpenSCAD file that uses these parameters and modules to create the battery mount. The code should be well-commented and easy to modify. Let me know if you have any questions!

I need a mount that can handle both a NEMA 17 and a NEMA 23 stepper motor, but I also want to be able to use the same design as a bearing mount (specifically, for a 608ZZ bearing, also known as a skateboard bearing).

The mount should have a base plate with screw holes for mounting. On one side, there should be a sort of supporting arm or strut. I think it would be good to have two of these, mirrored on either side.

Here's what I have in mind for the dimensions, but these should be parameters that I can change later:

*   **ThicknessStepper:** 5 mm (thickness of the base plate)
*   **WidthStepper:** 56.2 mm (width and length of the base plate)
*   **ScrewsStepper:** 47.1 mm (distance between screw holes on the base plate)
*   **HeightFoot:** 25 mm (height of the support strut)

I'd like it to have a few parameters to switch between a Stepper and a Bearing mount. It should be straightforward to change between the two, where switching should change the center hole diameter.

*   **Stepper:** Set to 1 for a NEMA stepper, set to 0 for the bearing mount.

When set to **Stepper = 1**, there should be a center hole with a radius of 19.2mm. There should be 4 screw holes arranged symmetrically with a radius of 2.6 mm and the same `ScrewsStepper` distance apart. Also, I need two cylinder holes for securing screws on the strut, radius = 2.1 mm, 2/3 up the strut from the base.

When set to **Stepper = 0**, there should be two center holes. One with a radius of 8 mm and the other with a radius of 11.1 mm.

Could you generate an OpenSCAD file (or files) for this? I don't need to use any specific libraries, just whatever is simplest for you.

Alright, I need to create a parametric mount for various cylindrical devices, like motors or encoders. I've seen a few designs out there, but I'd like to be able to really customize it for different applications.

Here's what I'm looking for in terms of parameters and features:

**Basic Dimensions:**

*   **`length`**: This will be the overall length of the support structure.
*   **`Body_Diameter`**: The diameter of the main cylindrical body of the device being mounted.
*   **`Collar_Diameter`**: The diameter of any collar or shaft extending from the device, this is often smaller than the main body.
*   **`Body_Height`**: The height of the center of the device body above the base of the mount.
*    **`Support_Thickness`**: The thickness of the front support.
*   **`Tolerance`**: A small clearance value to ensure that the 3D-printed mount fits the device properly.

**Mounting:**

*   **`Mount_Points`**: The number of mounting screw holes around the device body.
*   **`Pitch_Circle_Diameter`**: The diameter of the circle formed by the center points of the mounting holes.
*   **`Mounting_Holes_Diameter`**: The diameter of the screw holes for mounting.
*   **`Screw_Countersink_Depth`**: The depth of the screw countersinks. A value of 0 means no countersinks.
*   **`Screw_Countersink_Diameter`**: The diameter of the screw countersinks.
*   **`Rotate_Holes`**: Option to rotate mounting holes so that one or two holes are at the bottom; this might be needed for offset shafts. It should be a boolean value, either 1 for yes, 0 for no.

**Additional Features:**

*   **`Add_Feet`**: Boolean option to include feet at the base of the mount, should take either 1 for yes or 0 for no.
*   **`Feet_Hole_Diameter`**: The diameter of the holes in the feet.
*    **`Full_Ring`**:  Option to add a full support ring above the device to hold it more securely. Boolean option: 1 for yes, 0 for no.
*   **`Shaft_Offset`**: A vertical offset for the shaft or collar. This is specifically useful for mounting things like Pololu gearboxes.
*   **`Polygon_Count`**: A setting to adjust polygon count to determine the resolution of curved objects. Should use values like 32, 64, 128, or 256, for low, medium, high, and insane, respectively.

**Design Details:**

*   The mount should have a rectangular base that extends on each side of the main cylinder.
*   The front face of the mount should have vertical support to provide structural integrity.
*   There should be an option to include a through hole to secure the mount with a cable tie. The location of this hole should depend on whether there are feet or not.
*   I would like to have a vertical cut out in the base to reduce printed material.
*   If feet are included, they need to provide a stable base. The amount of feet should be based on the length, with 1 set of feet for short lengths, and up to 3 for the longest lengths.
*   The code should make use of the `min()` and `ceil()` functions where applicable.

I think that covers everything. I would like all of the generated code to be in a single .scad file. Please let me know if anything is unclear or if you need more information, and thank you for taking on this project!

Hey, I'm working on a replacement steering linkage for a remote control car, specifically the part that connects to the shock tower via a ball stud. I've got a basic idea down in some existing OpenSCAD, but it's really rough and I need a parametric design that I can easily adjust for different setups.

Here's what I'm looking for, functionally:

*   It's a mostly cylindrical body with a hole for a threaded shaft (where it connects to the rest of the steering linkage) at the base and a ball joint socket at the other end.
*   The ball socket needs an insert to allow it to smoothly swivel, and that insert needs a sort of 'flat' side, so that a printed insert can be installed.
*   I need the design to be parametric, so I can easily change the shaft diameter, insert depth, overall height, ball diameter, and the height of the flat insert feature.
* I'd prefer if the flat side of the insert went through the entire circumference so an insert can be placed in either direction.
*   The final part needs to be rotated at an angle around the X axis to position the ball stud correctly for the shock tower mounting angle.

I'm not particularly worried about optimizing for printability beyond a few structural requirements - the biggest factor is the parametric design. I'm imagining a few OpenSCAD files, one for the main body and maybe one for the insert itself, since it would be easier to vary that independently. I'd prefer if the inserts were designed such that the center of the sphere they reside in is the same center as the sphere of the main socket.

I'm hoping you can generate a few .scad files to do that, including the rotation. I'm not using any specific OpenSCAD libraries, I can handle the details with standard primitives.

				cylinder(h=80, r=(ball_dia-insert_extra_dia)/2);
			}

I'm looking to design a parametric ramp for 3D printing, and I'd like your help creating the OpenSCAD files.

The ramp should have the following features:

*   **Adjustable Angle:** I need to be able to specify the angle of the ramp (e.g., 30 degrees).
*   **Adjustable Width:** The ramp should have a width that I can customize.
*   **Adjustable Thickness:** I need to control the thickness of the ramp's walls (this affects the sturdiness). It's important that the walls maintain a consistent thickness, even where the ramp curves downwards to meet the floor.
*   **Adjustable Length:** I need to be able to set the overall length of the ramp.
*   **Smooth Lip:** The bottom of the ramp should have a smooth transition to the flat surface it rests on, instead of simply stopping at an edge.

I'd like to be able to easily modify these parameters. I'd also like the OpenSCAD code to use clear variable names and comments to make it understandable. I'd like the code to be fully parametric, meaning that changing any of the above parameters should result in a correctly rendered ramp, as long as the values make sense (e.g., the thickness should be non-zero).

For libraries, I am okay with the use of the standard `math.scad` if you need it, or any standard built-in functions. I would _not_ like you to use any external libraries like BOSL, or similar. I also do not need a separate config file.

Could you please generate the OpenSCAD code to accomplish this? Thanks!

[Assistant]
ramp.scad:
```
// Parametric script for creating a printable ramp.

// The angle of the ramp.
theta = 30;

// How wide the ramp is.
width = 50;

// The minimum material thickness to use. The ramp will end up being a bit thicker at the points, but it will have this thickness on the walls.
thickness = 3.0;

// The length of the ramp.
ramp_length = 50;

// computed parameters
outer_triangle_height = sin(theta) * ramp_length;
outer_triangle_base = cos(theta) * ramp_length;
outer_triangle_hypot = ramp_length;

// even though the material width is x, you can't just add x all around if you want a smooth ramp lip
// the key is to realize that there's a right triangle you can draw that's similar to the main triangle
// and them from that you can draw another right triangle to fill in the space until the rectangular
// wall begins
//
//    /|\   /
//   / | \ /
//  /  |  /
// / A | / A hollow interior

// the upper triangle has a leg of "wall thickness" and an angle of 180 - 90 - theta
// which lets us compute the upper triangle's hypotenuse
// sine(theta) = thickness/hypotenuse => hypotenuse = thickness/sine(theta)
upper_hypot = thickness/sin(90 - theta);

// upper_hypot is one leg of the bottom triangle. we can use tangent to find the base, which is the
// delta between the ramp lip and the interior
// tan(theta) = Opp/Adj => Adj = Opp/tan(theta)
lip_base = upper_hypot/tan(theta);

// for the upper corner, we have this
//     /|
//    / |
//   /  |
//  / /||
// / / ||

// can form a square of wall thickness on each side, but that leaves you a right triangle
// whose hypotenuse is the far wall of the ramp drop-off
// the inner tip of the triangle is thus offset that hypotenuse (vertical)
// and the the hypotenuse of the triangle formed by joining the top across to the side and using
// wall thickness as a leg

non_ramp_angle = 90 - theta; // because triangle is 180, and we know there's a 90 in lower right
y_offset_1 = thickness/sin(non_ramp_angle);

final_tip_angle = 180 - (90 + (90 - theta));
complementary_angle = 180 - final_tip_angle - 90;
y_offset_2 = thickness/tan(complementary_angle);

total_y_offset = y_offset_1 + y_offset_2;
x_offset = thickness/sin(complementary_angle);

// y offset = sine(90 - theta) = thickness/y_offset => thickness/sin(90-theta) = y_offset

inner_triangle_y_offset = thickness/sin(90 - theta);

// x_offset = cos(180 - 90 - theta

	polygon(points=[[0,0],
	  [outer_triangle_height,0],
	  [0,outer_triangle_base],
	  [0,outer_triangle_base - lip_base],

Hi, I'm looking to create a parametric OpenSCAD design for shelf brackets, similar to the "Shelfie" design on Thingiverse, but I want to make sure it's flexible enough for various material thicknesses and mounting options.

Essentially, I need a system that can generate L, T, and X shaped brackets, as well as L and T shaped brackets with foot extensions, all with customizable parameters.

Here are the features I need:

*   **Bracket Types:** The design should generate L, T, and X brackets as well as L and T shaped brackets with "foot" extensions for additional stability.
*   **Customizable Dimensions:** I need to be able to set the overall `bracket_size` (cube size), the `panel_thickness` for both panels (they might be different), and the `wall_thickness` of the bracket itself.
*   **Flip Option:** For the L and L-foot brackets, I'd like a `flip` option to mirror the bracket for different orientations.
*   **Base Thickness:** A customizable `base_thickness` would allow for adjustments in how the bracket connects or sits on a surface and be set to zero to allow for mid-panel mounting on both panels.
*   **Hole Radius:** I need to define the radius for screw holes using a `hole_radius` variable, and I would like them to be countersunk. If the `hole_radius` is set to 0, the holes should be removed.
*   **Pass Through:** I'd like a `pass_through` option to allow a panel to extend beyond the bracket on one or both sides. This may impact the internal bracing.
*   **Bracing:** An `internal_bracing` option to remove bracing on all the pieces, which I would want to be able to allow the sides to butt up together without gaps.
*   **Wall Mounts:** A `wall_mount` option to add a wall mounting plate to the brackets. When set, the wall mounts will be on the two sides of L bracket.
*   **Wall Mount Corner Radius:** A `wall_mount_corner_radius` parameter to round the corners of the wall mount area. It should be limited by half of the `bracket_size` to make sure it doesn't create a self-intersection when rounded.

I'd really like this to be done in one or more parametric OpenSCAD files. I don't need any special libraries, just the core OpenSCAD functionality. I've seen a few designs around, but they're always missing a feature I need. I also am not sure if the user would want to combine the `pass_through` with no `bracing`.

'Shelfie' Do it yourself shelf and storage designer by: Mike Thompson 10/4/2015, http://www.thingiverse.com/mike_linus
Based on original concept idea from Milla Niskakoski http://www.thingiverse.com/thing:681835

v2 18/1/2017 - Added 'no internal bracing' option to allow panels to butt together and a corner radius cut-off option for wall mounting
v3 16/4/2017 - Fixed L and T Foot rendering for small cube sizes
v4 6/11/2023 - Added countersinking to holes and set limnt on wall mount corner radius

I was very impressed with the simplicity and practicality of Milla's initial design, but ran into some major limitations when trying to
construct my own shelves.  The key issues I encountered were:
- No customisable thicknesses. Like may others, I wanted to use the scrap wood I had lying around rather than purchase new material.
- No mixed thicknesses. I wanted to use glass shelves with wood sides, but it wasn't possible unless they were the same thickness.
- No wall mounting bracket option.  Particularly for tall shelves, this is an important safety feature.
- No ability to alter the size of the bracket or the wall thickness to increase strength.
- No ability to attach a shelf midspan.  This is a big issue if you have long sections and want to add a shelf in-between.

Shelfie provides full control over all parameters so you can mix materials of any thickness, add wall mounts, alter the bracket size,
mid mount shelves, change the screw hole size etc.

Note: incremental 0.01 values added to fix diplay anomalies when using preview (F5)

Hi, I'm looking to have a parametric OpenSCAD design created for a replacement tube holder for a laboratory rotator, specifically the Stuart SB3 rotator. The current design I have (which I'm attaching) works, but it's not as customizable as I'd like it to be. I really need more control over the dimensions to make it useful for different tube sizes and rotator models in the future.

Essentially, the holder needs to have a base that fits onto the rotator's rotating plate, a slot to hold an eppendorf tube (or other similar tube), and a top piece that secures the tube. The base of the current design is a square, which works ok, but it would be great if that could be changed too. The way it holds the tube is through a circular slot, maybe that can be parametrically controlled and be different shapes in the future.

Specifically, I would like the following parameters to be easily adjustable in the new design:

*   **Base Shape:** I want to be able to choose between a square base (like the current one), a circular base, or even an octagonal base that can be specified with side-length or radius.
*   **Base Dimensions:** The size of the base (width/diameter) and height should be adjustable.
*   **Tube Slot Shape:** I want to be able to choose between a circular, square, or maybe even a polygon tube slot to allow for different tube styles, not just standard eppendorf tubes. I would like to define a parameter for the sides or radius for these slot types.
*   **Tube Slot Dimensions:** The inner and outer dimensions of the tube slot, including depth/height should be adjustable to accommodate different tube diameters and heights.
*   **Top Piece Height:** The height of the top piece should be adjustable and should match the tube slot opening height.
*   **Tube Slot offset from base:** The distance of the tube slot from the center of the base.

It would be amazing if it were done in a way that it is clear which modules are responsible for what and easy to change, making the code easy to understand. I think the core of this project could use several modules for the main parts, like the base module, a tube slot module, and a top piece module, which then can be combined.

I'd prefer to use the BOSL2 library, if possible. I think it would be very helpful to get the different base options I am requesting.

Attached is the current design I have, `eppendorf_holder_LPG.scad`. Thank you so much for your help!

I need an OpenSCAD design for a bird spike system that can be mounted on a pole. The spikes should radiate outwards from a central clip that attaches to the pole.

Here are the specific parameters I need to control:

*   `pole_dia`: The diameter of the pole the clip will attach to.
*   `pole_thick`: The thickness of the clip material around the pole itself.
*   `pole_h`: The height of the clip along the pole axis.
*   `spike_l`: The length of each individual spike.
*   `spike_h`: The height of each individual spike (the dimension perpendicular to the pole).
*   `spike_w`: The width of each individual spike.

I want the design to use five spikes, spaced evenly and angled outwards slightly. I think rotating each spike by +/- 22.5 degrees, and +/- 45 degrees from the middle one should do the trick. I'd prefer the spikes to be simple rectangular cuboids.

The clip itself should be a cylinder with a cut-out to allow it to snap onto the pole. I think two cylinders subtracted from the main clip cylinder should work - one for the pole and another for the split. The cut-out cylinder should go a little further around than just the pole radius to create a small gap to allow it to clip. Let's make sure the clip is a little taller than necessary, and we'll make the cut cylinders a little taller than the clip cylinder as well, to ensure we get clean edges.

It would be great if this was fully parametric, so I can adjust the dimensions as needed. I don't need any fancy libraries, just the basic OpenSCAD functionality. Could you provide the .scad file for this?

pole_h = 10;    // height of the clip

$fn = 48;

pole_r = pole_dia/2;

I'm looking to create a parametric model of the Atomium, similar to the one I saw online, but I want to be able to customize it more easily for 3D printing. Specifically, I'd like to be able to choose between printing the full Atomium structure or just the central "atom" part. The current model seems to be made for visualization instead of printing.

Here are the main things I want to control:

*   **Overall Scale:** I need to set the dimensions of the cube that defines the basic "atom" structure. This should affect the size of the balls and tubes. In the existing code, this seems to be `cubeSize`, but I'd like to make this very explicit.
*   **Ball Diameter:** The diameter of the spheres at each corner and in the center.
*   **Tube Diameter:** The diameter of the cylinders connecting the spheres.
*   **Bottom Elevation:** The height of the lowest sphere (or the base of the overall structure if making the Atomium) above the ground plane.
*  **Base Options (Atomium only):** For the Atomium model, I'd like to control:
    *   The number of sides of the base polygon (0 for a circle).
    *   The thickness of the base.
*   **Option for "atom" or "atomium":** I want a simple toggle to choose between rendering the full Atomium or just the central atom structure.
*   **Simplified Bipod:** The supporting bipods for the Atomium are quite complex. I'd prefer a simplified version that's easier to print, maybe just a single support that can be duplicated using the rotation. I'd like to control the thickness and width of the bipod.
*  **Overall rotation:** I need the overall structure to be rotated as it is in the existing design: `rotate([45,-35,0])`. I'd want this transformation to be a single variable, so that it can be easily changed.
*   **Printability:** I need the model to be more suitable for printing. This probably means breaking up the bipods and base into separate, printable pieces that could be assembled. I'm okay with assembling a few pieces if it makes it easier to print.
*   **No custom libraries**: I don't want to use any custom libraries for this, so I'd prefer if you just used the standard OpenSCAD functions.

Essentially, I'm looking for a more printer-friendly version of the Atomium, with easy-to-use parameters and the ability to choose between the full model and just the central atom.

Could you generate the OpenSCAD code for this? Thanks!

Hey, I'm looking to design a flexible coupling for a Z-axis leadscrew on a 3D printer, and I need some help with OpenSCAD. I have a design in mind based on a previous one, but I want to make it fully parametric and easier to customize.

Here's what I'm thinking:

**Overall Goal:** Create a coupling that connects a 5mm diameter motor shaft to a 6.35mm (1/4 inch) diameter leadscrew. The coupling needs to be flexible enough to accommodate slight misalignments and potentially address Z-wobble. I need two versions of the coupling, one with the leadscrew hole offset to potentially correct for Z-wobble and another with the leadscrew hole centered.

**Key Features and Parameters:**

*   **Shaft Diameter (`shaft_dia`):**  This will be 5mm for the motor shaft.
*   **Leadscrew Diameter (`studding_dia`):** This will be 6.35mm.
*   **Asymmetry (`asym`):** This is the horizontal offset of the leadscrew hole from the center, used to help with wobble. It needs to be adjustable, so it should be a parameter. It should be set to 0 for a non-offset coupling.
*   **Coupling Height (`height`):**  The overall height of the coupling; I was thinking around 35mm, but this should be variable.
*   **Coupling Width (`width`):**  The width of the coupling - I used 23mm previously, this should also be configurable.
*   **Coupling Thickness (`thickness`):** How thick the coupling is; something like 8mm.
*   **Mounting Hole X Distance (`holeX`):** The distance of mounting holes from the center in the X direction - around 10.5mm in my earlier model.
*   **Mounting Hole Y Distance (`holeY`):** The distance of mounting holes from the center in the Y direction - I used 6.5mm before.
*   **Mounting Hole Radius (`holeR`):** The radius of the mounting holes themselves, 3.4mm diameter before.
*  **Nut Radius (`nutR`):** The radius of the recess for the nut, 3.25mm previously.
*   **Nut Height (`nutH`):**  The depth of the nut recess - around 3mm.
*   **Bolt Head Radius (`boltheadR`):** The radius of the recess for the bolt head, 3mm.
* **Rounding Radius (`rounding_radius`):** The radius of the rounded corners of the coupling. This should be a separate parameter for easy adjustment.
* **Bolt Type ( `bolt_type`):** A variable which specifies whether to use nuts or directly bolt into threads; defaults to 'bolt'

**Specific Design Details:**

1.  **Rounded Cube:** The main body of the coupling should be a rounded cube for both couplings. Use a minkowski sum to achieve the rounded corners.
2.  **Shaft and Leadscrew Holes:**  The coupling needs a central hole for the motor shaft and another for the leadscrew. The leadscrew hole position will be determined by the `asym` parameter.
3.  **Mounting Holes:** Four mounting holes need to be included to secure the two halves together.
4.  **Nut/Bolt Recesses:**  Recesses are needed for nuts, or bolt heads, depending on the bolt type selected.
5.  **Bridge:** A small bridge between the nut recess and the outside of the coupling is required to hold the nuts (or bolts).

**Two Coupling Versions:**

*   **Version 1 (Non-Offset):**  This coupling has `asym` set to 0, so both shaft and leadscrew holes are centered. This is the equivalent of my grey model.
*   **Version 2 (Offset):** This coupling has an adjustable `asym` value. This corresponds to the orange coupling in my description.

**Libraries:**
I would prefer this to be done without any external libraries if possible, but if there are any useful modules in BOSL2, then feel free to use them.

**Output:**
I'd like to get a set of SCAD files, ideally one main file and any necessary modules, all designed to be easy to customize through the parameters I've described.

Let me know if you have any questions, and thanks for your help!

Hi, I'm looking to design a parametric spool holder for 3D printer filament spools, and I'm hoping you can help me generate the necessary OpenSCAD files. I've got a basic design in mind that I've built pieces of, but I need to make it parametric.

Here's the overall idea: it’s a cone-shaped holder with a bearing recess in the center, which fits onto a rod. There should be cutouts to save on material too. I would like to have a clip that would hold it together. I have previously made files for the holder itself, a washer, and a clip. I can provide these for reference, but I would like you to create the files from scratch, I'll just use these as reference. The files I have are `spool_holder.scad`, `washer_608.scad`, and `clip.scad`.

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

*   **Bearing Diameter (bearing_d):** This will be the diameter of the bearing that sits in the center recess. Initially it will be 22mm for 608 bearings, but I would like to make this adjustable.
*   **Bearing Height (bearing_h):** This is the thickness of the bearing. It should also be adjustable.
*   **Max Holder Diameter (max_d):** The diameter of the wide base of the cone. This needs to be adjustable based on spool sizes.
*   **Min Holder Diameter (min_d):** The diameter of the narrower top end of the cone. Also adjustable.
*   **Cone Height (cone_h):** The height of the cone.
*   **Rod Diameter (rod_d):** This is the diameter of the rod that the spool holder sits on.
*   **Washer Outer Diameter (washer_od):** The outer diameter of the washer that sits between the bearing and holder
*   **Washer Inner Diameter (washer_id):** Inner Diameter of the washer
*   **Washer Height (washer_h):** Height of the washer
*   **Clip Inner Diameter (clip_id):** The diameter of the circle cut out of the clip. This should be slightly smaller than the rod diameter to be a tight fit.
*   **Clip Width (clip_width):** Width of the clip material
*   **Clip Height (clip_h):** Height of the clip
*   **Clip Tab Length (clip_tabl):** Length of the tabs on the clip

For the `spool_holder.scad` design, I'd like it to:

*   Create a cone using `cylinder()` with `r1`, `r2` and height.
*   Create a cylindrical cutout for the bearing.
*   Create a cylinder for the rod hole.
*   Create 4 cylinders for material saving that are evenly spaced around the design.

For the `washer_608.scad` design, I'd like it to:

*   Create a cylinder for the main body of the washer.
*   Create a second cylinder to cut out the center of the washer.

For the `clip.scad` design, I'd like it to:

*   Create a cylinder for the main body of the clip.
*   Create two cubes at angles to function as tabs.
*   Create a cylinder cutout in the center.
*   Create a cut out to make the clip usable.
*   Create a cut out to further make the clip function well.

I think that covers the core functionality and adjustability I need. Please let me know if you need more information or clarification on any of these parameters. I would like the code to be generated from scratch, using my files only as inspiration. I would like to see the final `spool_holder.scad`, `washer_608.scad`, and `clip.scad` files. Please make sure that the code is properly formatted and commented so that I can easily understand it. Please use the built-in OpenSCAD functions and not any external libraries. Thanks!

I need a design for a clip that can attach to a standard spray paint can and hold one of those thin red tubes that come with lubricant sprays. I have a general idea of the shape in mind, but I'd like to be able to customize several aspects of it.

Specifically, I'd like to control:

*   The diameter of the spray can it's designed to fit.
*   The diameter of the tube it's meant to hold.
*   The width and height of the clip section that wraps around the can.
*   The height of the section that actually holds the tube.
*   The thickness of the base of the tube holder.

The clip should wrap around the can with a curved shape, and the tube holder should protrude out from that. It should be a single, printable piece, without any additional parts. I'd prefer if the design was done parametrically using OpenSCAD so I can adjust these values easily myself. I also need to make sure it fits onto the actual can. I don't want to have to guess at where to measure.

I also would appreciate it if the design took into account the tolerances for printing, so that it fits snuggly without being either too loose or too tight. I'm not sure how much clearance to leave for my printer. I'd be using PLA on a consumer FDM printer, if that helps. Let me know if I need to provide any other information.

I'd like the design to be fairly robust, with a focus on durability for general use. I don't need it to be super lightweight.

I need a custom bottle cap generator in OpenSCAD. It should be parametric, so I can easily change the size.

Here are the key parameters I want to control:

*   `bottlerad`: This is the radius of the bottle's neck where the cap will attach.
*   `border`: This is the thickness of the bottle's rim or lip that the cap needs to fit over.
*   `thick`: This defines the thickness of the plastic (or material) used for the cap's walls.
*   `depth`: This determines how deep the cap will sit on the bottle neck.
*   `top`: This is the extra height added to the top of the cap, above the bottle neck depth.

The cap should essentially be a hollow cylinder. There should be two cylinders subtracted from the main cylinder: one to create the inner bore that fits around the bottle's neck, and another concentric one to create the outer wall.

I need to be able to easily adjust these five parameters to make a cap for various bottles. I’m hoping for a design that looks like the one in the example, but I’d prefer for it to be completely parametric (i.e. have all of the parameters exposed). The example provided shows the use of a `difference()` operation between the main cylinder and the other cylinders to create the cap; please use that technique in your design. The design doesn’t require any complex features or special libraries, and the example didn’t use any, so it should just use the core OpenSCAD primitives. I don’t want any fancy features, just a basic functional bottle cap.

// How long the bottle will penetrate into the cap
depth=7; // [5:15]

// Extra value for the printed top of the cap

Hi, I'm looking to create a customizable adapter, primarily for use with vaporizers but really it should be flexible enough to connect different tubing or fittings. I've seen something similar before on Thingiverse, ID 763031, but it's not quite what I need, and it's not as flexible as I'd like. I want to be able to control a bunch of parameters.

Here's what I'm after:

The adapter will have a generally cylindrical shape, but with at least two different diameters and a central hole running the entire length. The general shape will be that of a wider cylinder, followed by a narrower cylinder, both sharing the same center axis.

**Key Parameters:**

*   **`diameter_1`**: This will be the width of the *wider* part of the adapter. I need to be able to set this in mm.
*   **`diameter_2`**: This is for the *narrower* part's width, also in mm.
*   **`adapter_length`**: The total length of the adapter (not including any 'button').
*   **`internal_diameter`**: The diameter of the hole that runs through the adapter.

**Button Feature:**

I also want a "button" feature on one end. This part will be like a disc or a short cylinder that's on the end of the wider cylindrical section. I'd like to be able to control:

*   **`button_width`**: The diameter of the button in mm.
*   **`button_thickness`**: How thick the button is.
*   **`button_taper`**: A percentage value, that tapers the button on the end, for example, 0 is no taper, and something like 50 would create a significant taper. I need the taper to be adjustable in either direction - so positive percentage will taper outward, negative will taper inward, and zero will mean no taper.

**Additional parameter:**

*   **`easy_valve_diameter`:** I'd like to include a diameter for another specific part at the start of the model - this would be the end that is *not* attached to the button.

I need the whole thing to be parametric so I can easily tweak these parameters and generate a new adapter. The code should be robust - I don't want it to break if the user enters silly numbers. I'm particularly concerned about avoiding the creation of parts which would result in invalid geometry. For example, if the internal diameter is somehow larger than the external diameters, it should either throw an error or, at least, cap or adjust to produce a solid model. The internal diameter should always remain a void.

Also, please make sure the code is well commented. I'm still learning OpenSCAD. I don't need to be able to use any additional libraries or includes, I would prefer just raw OpenSCAD.

Thanks!

I'm looking for an OpenSCAD design for a customizable dog tag. It should be a rectangular shape, specifically 50mm wide, 20mm deep, and 4mm thick. I need to be able to add a name to it, which should be centered on the tag and have a thickness of 4mm. The name should be raised from the tag surface, not engraved. Also, I'd like a small cylindrical hole for attaching a ring, about 3mm in radius and 6mm tall. This hole should be offset from the center, towards the right side of the tag. Can you use the "write" library for the text and generate the .scad files?

I also need the text to be able to be toggled for bolding.

[Assistant]
Untitled.scad:
```
// include <MCAD/filename.scad>
// include <pins/pins.scad>
include <write/Write.scad>
include <write.scad>

name_text = "Will";

difference(){
	translate([-25,-10,-2]){
		cube([50, 20, 4]);
	}
	write(name_text, t = 4, h = 12, center = true, bold = 1);
	translate([20, 0, -2]){
		cylinder(r = 3, h = 6);
	}
}

I'd like a parametric spool holder designed in OpenSCAD. I have a basic idea of what I want, similar to the "Compact Spool Holder" design I saw, but I need it to be more robust and adjustable. I'm looking to support different spool sizes and potentially different bearing sizes in the future.

Here's what I'm thinking:

**Core Structure:**

*   A base plate with adjustable inner and outer diameters for the spool. I’d like the ability to specify not only the diameter but also the thickness of the plate.
*   A raised circular section to hold the bearing, also with adjustable diameter and height. It should be designed to use standard bearings.

**Bearing Support:**

*   The design should have a way to securely hold the bearing. It should include a feature to prevent the bearing from popping out and also to allow for easy removal. Perhaps a slight interference fit with a chamfer would be best.
*   I also need to be able to adjust the width of the bearing support.

**Customization & Parametric Options:**

*   **Spool Inner Diameter:** Adjustable parameter for the spool's inner diameter.
*   **Spool Outer Diameter:** Adjustable parameter for the spool's outer diameter.
*   **Spool Plate Thickness:** Adjustable parameter for the thickness of the spool support plates.
*   **Bearing Diameter:** Adjustable parameter for the outer diameter of the bearing.
*   **Bearing Support Diameter:** Adjustable parameter for the diameter of the raised support for the bearing.
*   **Bearing Support Height:** Adjustable parameter for the height of the raised support.
*   **Bearing Support Width:** Adjustable parameter for the width of the bearing support.
*   **Bearing Chamfer Angle:** Adjustable parameter for the chamfer angle to allow for easy bearing insertion and retention.
*   **Overall Height:** Adjustable parameter for overall height of the structure.
*   **Z-Axis Support Option:** An option to include or exclude a Z-Axis support block as a separate part that can be attached to the holder with screw holes. The size and number of holes should be parametric.
*   **Screw Hole Size** Variable for the diameter of the z-axis support screw holes.
*   **Screw Hole Separation** Variable for the separation between screw holes.

**Material Considerations**

*   The design should be easy to 3D print, avoiding overhangs where possible (or keeping them minimal).
*   A few key parameters for tolerance would be welcome to ensure a good fit.

**Output:**

*   I'd prefer to have two .scad files. One for the main spool holder and one for the optional Z-axis support block.

I believe that covers everything. Please generate the OpenSCAD files based on these parameters. I don’t have any specific library requirements, so just use what you think is best.

I'm looking to create a parametric design for window blind boxes, the kind that house the rolled-up blind when it's open. I have some basic dimensions and an idea of the internal structure, but I need help making it a flexible design in OpenSCAD.

Here's what I'm thinking: The main box is a rectangular prism, and I want to specify the length, height, and depth of this box. The thickness of the material is also important.

Inside the box, I need a number of vertical supports and horizontal supports. I want to be able to control the number of each of these and their height. These supports should be attached to the *inside* walls of the box, not just free-floating in the middle. I’d like to specify the depth of the recesses where these supports attach to the box walls. This might sound like a dado cut on a piece of wood. Also, the supports should be a certain thickness/depth, and the supports should not extend past the exterior depth/width of the main box.

Also, I need an "exploded" view, kind of like an orthographic projection, where each internal part is laid out flat. I'd like to see the main box as a flat 2D piece, the vertical supports as flat 2D pieces, and the horizontal supports also as flat 2D pieces. The main box should show the shape including the recesses.

Finally, I'd like to be able to include an "underplate", which closes off the bottom of the structure. It should have the same length and depth as the main box, and should match the dado cut pattern for the vertical supports as well.

Can you create this parametric design in OpenSCAD? I'd like it to be clear and well-structured, so I can easily modify the parameters to create different sizes of blind boxes. I would really appreciate comments in the code, too, as I'm still learning OpenSCAD. I’m okay with the whole design being in a single .scad file if that's easier.
