Hey, I'm looking to create a parametric model for what I call "machinist lego blocks" - essentially, blocks with a grid of holes that can be used for fixturing. I'd like the design to be based on the following parameters:

*   **Bolt Diameter:**  The diameter of the holes, this needs to be adjustable as some taps and bolts are slightly different sizes (specify a diameter value, not a radius value)

*   **X, Y, and Z Grid Size:**  I want to be able to specify how many holes there are in each direction along each axis.

*   **On-Center Spacing:** The distance between the center of the bolt holes along each axis.

The overall block should be a rectangular prism, and the holes should go all the way through the block.  For each of the three axes, there should be 1) a set of holes along that axis that are drilled through the center of the block, and 2) sets of holes in the other two axes that go all the way through. For example, if you have a 3x3x3 grid, this means:

*   There would be 3 holes along the x-axis that pass directly through the center of the block,
*   there would be 3 holes along the y-axis that pass directly through the center of the block,
*   there would be 3 holes along the z-axis that pass directly through the center of the block,
*   and there would be 3x3=9 holes that pass through the block along the x and y axes
*   and there would be 3x3 = 9 holes that pass through the block along the x and z axes
*    and there would be 3x3 = 9 holes that pass through the block along the y and z axes

I think that sums it up.  I don't need any fancy features on it, just the basic block with all of these holes. I think it will be best to have an option to change the $fn for the cylinders. Could you generate an OpenSCAD file for me? No need for any libraries for this one. I don't think I would need them.

Hi, I'm looking for an OpenSCAD design for a replacement tripod head base. I have the dimensions I need, and I'd like to make it customizable.

Essentially, it’s a cylinder with a beveled top and a central hole. The hole needs to have options for being straight or tapered, and I also need to be able to choose whether to include a space for a nut under the cap. I’d like all of this to be parametric, so I can easily change things like the height, diameter, and nut size.

Here are the specifics:

*   **Base Body:** This is the main cylinder. I need to be able to set the height (`body_height`) and diameter. The top edge of the base body should be beveled
*   **Bevel:** The top of the cylinder should have a bevel. I need to be able to set the bevel height (`cap_height`).
*   **Central Hole (Shaft):** This goes through the entire piece. I need to set the shaft diameter (`shaft_diameter`) and the shaft height (`shaft_height`), and I should be able to choose whether the hole is straight or tapers to the top (`taper_shaft`).
*   **Nut Recess:** I need an option (`nut_under_cap`) to add a recess for a nut under the cap. If I choose to include it, I need to specify the nut size (`nut_size`), the nut thickness (`nut_thickness`), and the nut height (`nut_height`). Note that this nut space should not extend into the base body itself - it should only be in the portion that goes above the top of the base body, so `nut_height` should be calculated relative to the end of the shaft, not the beginning of the base.
* **Indexing Slots:** There should be two rectangular slots on top of the beveled cap. They should be symmetrical across the center, and I need control over their position.

I think that covers it. I'd like to use the Customizer functionality if possible. No specific libraries are needed, but please use best practices for OpenSCAD.

Thanks!

I'm looking to create a housing for a small thermometer module, specifically the kind that's readily available on AliExpress. I've seen them used in 3D printer enclosures, which is what I'm planning to do.

I need a parametric design in OpenSCAD, and I'd like to be able to customize the text displayed on the bottom. The basic shape is a box with an inclined face. Here are the main parameters I'm thinking of:

*   **Module Dimensions:** The thermometer module itself will have a width, height, and depth, which need to be accounted for in the internal cavity.
*   **Overall Box Dimensions:** The box should have an overall width, height, and depth.
*   **Wall Thickness:** I need to define the thickness of the box walls.
*   **Text:** The text displayed on the bottom should be customizable, along with its size and height.
*   **Cable Hole:** A hole is needed for the sensor's cable. I want to specify this hole's diameter.
*   **Stand Height:** The box will have a base that raises it off the mounting surface. I need to specify that stand height.
*   **Incline:** The main face of the box should be inclined at a certain angle.
*   **Edge Radius:** I'd like to add a small radius to the edges of the box.

So, in essence, I need a parametric box with a specific internal cavity, an inclined face, a cable hole, and customizable text on the bottom. I'd like the design to be robust and easily customizable for different module sizes or mounting scenarios down the line. I'm happy to start with a basic version and refine it. I would like this to use the BOSL2 library for any advanced features you may want to utilize, like the rounded edges.

Hey, I'm looking to create a parametric vase design in OpenSCAD, and I have a pretty specific concept in mind. I'd like the vase to be based on the shape of the letter "X", but not just a simple extrusion. I want it to be hollow, like a vase should be, and it should have some rounded corners.

Here's the basic idea: the overall form is an "X" shape, and the vase will be made by extruding that shape vertically, with a twist. I'd like to be able to control the overall height of the vase, the width of the "X" shape at the base, and the thickness of the walls. It should have a solid bottom as well, of equal "X" shape and thickness to the wall. Think of the main body of the vase as twisting 180 degrees from bottom to top. The bottom solid base should also have a twist, but much smaller twist, proportional to the wall thickness. The corners of the X shape should be rounded, like in the provided code, using circles or similar. I think you will want to create modules for "solid_shape" and "hollow_shape" and then assemble those into the final "vase" module, which will use linear extrude.

Could you generate the OpenSCAD code for this design? I am not using any particular libraries, so everything would need to be from scratch. Let me know if you have any questions.

I need a parametric design for a tool shelf, something to hold screwdrivers, paint brushes, and similar items. I want to be able to adjust the number of holes on each shelf, the spacing between the holes, and the diameters of the holes individually per shelf, and the shelf depths and heights.

Specifically, I'd like the design to have three shelves: a rear shelf, a middle shelf, and a front shelf. I need to be able to control the height and depth of each shelf. I'd also like to set the diameter of the holes on each shelf independently. The design should include side walls to support each shelf, and if the overall width is above a certain point (say 100mm) it should automatically add a middle support wall. Finally, there should be back slates to provide extra support and make sure all the levels are held together. I want the design to be parametric in OpenSCAD and fully customizable using variables.

Here's a summary of the parameters I need:

*   `number_of_holes`: The total number of holes per shelf. This will be the same for all shelves, I guess.
*   `spacing_of_holes`: The distance between the center of each hole.
*   `rear_hole`: The diameter of the holes on the rear shelf.
*   `mid_hole`: The diameter of the holes on the middle shelf.
*   `front_hole`: The diameter of the holes on the front shelf.
*   `rear_height`: The height of the rear shelf.
*   `mid_height`: The height of the middle shelf.
*   `front_height`: The height of the front shelf.
*   `shelf_depth_rear`: The depth of the rear shelf.
*   `shelf_depth_mid`: The depth of the middle shelf.
*   `shelf_depth_front`: The depth of the front shelf.
*   `wall_thickness`: The thickness of the walls.

I believe that's everything. I'd like the final design to be generated in a single `.scad` file. No additional libraries are necessary, as far as I know.

Okay, so I've got this wooden train set, and the bridge supports are always falling over. I've designed some supports in OpenSCAD, but they're a bit basic and I'd like something more robust and parametric that I can easily adjust to different track sizes or desired heights in the future.

Here's what I'm thinking:

I need a design for a train track support that clips onto the track itself, like my previous design, so that it's really secure, and also supports the bridge or raised track pieces. The core structure would be two vertical arms connected at the base, each with a section to clip onto the sides of the wooden train tracks. Then, a support that comes out to meet the bottom of the bridge.

The main parameters I need are:

*   `track_width`: The width of the wooden train track.
*   `track_height`: The thickness/height of the wooden train track.
*   `support_height`: The height of the support up to the bottom of the bridge/raised track.
*   `support_width`: The width of the support section that comes out to meet the bridge.
* `clip_thickness`: the thickness of the "clip" sections that grasp onto the track.
*   `thickness`: The general thickness of the support's structure.
*   `clip_depth`: How far the "clips" extend in under the track.

I need the following features:

1.  **Track Clips:** The support needs two arms with a "clip" feature to hook onto the wooden train track on both sides. This clip should go down the side and extend under the track, with enough room to make it a secure fit, but not so tight as to be difficult to put on. This should probably be a sort of "C" shaped cutout to go around the track, leaving the top of the track free of interference.
2.  **Vertical Support:** The two track-clip arms should extend upwards vertically with the `support_height`.
3.  **Bridge Support Arm:** From the top of the vertical supports, a horizontal arm should extend inwards to the center of the track, and this arm should be `support_width` wide.
4.  **Parametric Design:** It should be easy to change the `track_width`, `track_height`, `support_height`, `support_width`, `clip_thickness`, `thickness`, and `clip_depth` parameters.
5.  **Robust Design:** The structure should be solid to make the supports strong, not just thin bits.
6. **Minimalist:** I'm looking for a relatively minimalist design; as little material as possible while still fulfilling the above criteria.
7. **Easy Printing:** It should be able to be printed without supports, and I would like a chamfer on the bottom edge of the clips.
8. **Rounded Edges:** All corners should have a slight radius, so no sharp edges.

Can you create a parametric OpenSCAD file for this? I don't need any custom libraries here, just the default OpenSCAD primitives. Thanks!

Hey, I'm looking for some help creating a parametric crystal generator in OpenSCAD. I've seen a few cool ones, but I want one that's a bit more flexible.

Specifically, I'd like to be able to control:

*   **Number of sides:** The crystals should have a variable number of sides, like a polygon. I'd like to set this as a parameter, and I don't really want to go above 10 because it starts looking too rounded at that point.  It should default to 6.

*   **Overall Shape:** The basic crystal should be a sort of random, spiky shape. It will be composed of a base that's like a hemisphere that the spikey bits will be on top of.

*   **Individual Crystal Spikes:** I want to generate a bunch of individual crystal-like spikes growing out of the hemispherical base. I need to control:
    *   **Size:** Each spike should have a random size for each crystal.
    *   **Position and Rotation:** Each spike should also have a random position and rotation within a limited range, so they don't overlap or end up too far from the center.
    *   **Shape:** Each spike should be composed of two cylinders attached to one another. The first cylinder goes directly upward from the sphere base and narrows as it goes up. The second cylinder should be attached on top of the first and should narrow down further to form a point.

*   **Randomization:** The size, position, and rotation of each spike should be randomized within a range using the `rands()` function so that every run of the generator can produce different random shapes of crystals and I want to be able to make multiple instances with a different seed for each of them.

I don't think I'll need any special libraries - the standard OpenSCAD functions like `cylinder()`, `sphere()`, `translate()`, and `rotate()` should be enough to make something that matches my description, along with the `rands()` function. Could you generate an OpenSCAD file with this functionality?

I'm looking to create a parametric design for a project enclosure, something like a box with rounded edges and a lid. I'd like to be able to specify the length, width, and the radius of the rounded corners. The base of the enclosure should have a lip or ledge on the inside edge, a small shelf, for the top to sit on. I want the enclosure to be hollow with a specific wall thickness which I'd like to parameterize.

Ideally, the design should use the Minkowski sum to create the rounded edges and I'd like the code to be easily customizable. I'm not very experienced with OpenSCAD, but I understand the basics. I'm not sure if I would want to use the MCAD library, but I'm open to suggestions if you think that it could make the code easier to read or maintain.

Hey, I'm looking to generate some fidget spinner designs in OpenSCAD, and I need a parametric script that's pretty flexible. I've seen a script that handles a lot of what I need, so I'll try to describe that and we can go from there.

I want to be able to specify the following parameters:

*   **Bearing Diameter:**  This will be in millimeters, and I need to be able to use different bearing sizes, so that should be a variable.
*   **Bearing Height:** Again, in mm.
*   **Bearing Hole Diameter:**  This is for the hole that the bearing goes in, again in mm, and needs to be slightly larger than the bearing's actual diameter.
*   **Number of Bearings:**  I might want to make spinners with 2, 3, 4, or more bearings, so this needs to be adjustable.
*   **Bearing Distance:** The spacing between the bearings, in mm.  This also determines the thickness of the fidget.
*   **Lock Height:** This is for the lock that helps secure the bearings, also in mm.
*   **Lock Diameter:** The diameter of the lock, in mm.
*   **Lock Bevel:** A boolean or binary variable, for whether to add a bevel to the lock, where 0 means no bevel, and 1 means yes.
*    **Resolution:** The number of facets to use for circles, also need to control this.
*   **Type:** I need a way to switch between a "linear" fidget design where the bearings are arranged in a straight line, and a "star" design with bearings arranged radially around a center bearing. Probably a variable with 1 for linear and 2 for star would be fine.
*   **Render Fidget:** A simple 0/1 toggle to enable or disable rendering the main fidget part.
*   **Render Locks:** Also a 0/1 toggle, for rendering the bearing locks but these only need to be rendered with the linear fidget type.

The linear fidget design should be basically a rectangular body with cutouts for the bearings and locks. The "star" design will have arms radiating out from a central bearing, each arm holding a single bearing. For the star design, the script should automatically calculate arm length based on the bearing diameter, the number of bearings, and spacing to prevent the arms interfering with each other. The locks should basically be cylinders with an inner hole. They should also support the option of a bevel.

I think it would be cleanest to have separate modules for the linear fidget, star fidget, and the lock. The linear fidgets will require a separate set of lock modules, as well. I think a basic difference/union would work for the main bodies and locks.

I *don't* need any libraries for this, I just want it all self-contained in a single OpenSCAD file or a couple of files.

// Here comes some logic about star arm length.
// Let's say that you want to put 10 608 bearings in a star shaped fidget.
// Depending on bearing diameter you should increase tha arm length to
// accomodate all of them without interfering each other and maintaining
// part integrity. So armlenght is choosen like this:
// As in the above example we then have 10 total bearings, 1 at the center
// and 9 on the arms. Each arm should have X=BEARINGDIAMETER+BEARINGDISTANCE
// between bearings centers. we have then a 9X perimeter circle whose radius
// is 9X=2*pi*R ==> R=9X/2pi, So, for 608 bearings, and a Bering dist. of 5mm
// R should be: 9*(22+5)/2*3.141592 = 38.67mm.
// Pretty good but we also need to know that our calc is assuming that the
// perimeter of the circle equals the sum of linear distances between centers,
// and this is only true when we have infinite bearings (expensive fidget, you know)
// so, we are going to feature a magic number to compensate the error, let's say
// 1.25 in practice. We then multiply this obtained radius by this delta.
// In the end R=38.67*1.2=46.40 mm. We could calculate the exact radius but
// this is enough for a toy.
// Finally we have to add BEARINGDISTANCE plus BEARINGDIAMETER/2 to accomodate
// the whole bearing. So: ARMLENGTH=46.40+(5+11) = 62.40mm.
// Ok. But beside this we have the other side of the problem, where we have
// let's say only 3 arms. The minimum radius should be:

Hey there, I'm looking to get some custom thread designs generated in OpenSCAD. I've seen some code floating around that's kinda complex and slow, so I was hoping to get something a bit more streamlined and parametric from scratch.

Here's what I'm after:

*   **Basic Thread Generation:** I need a module that can create a thread profile. I'd like to define the thread's *diameter*, *pitch* (the vertical distance per rotation), and overall *height*. The height should ideally adjust so that the thread has a whole number of turns, not just chopped off.

*   **Profile Geometry:**  The thread profile should be a trapezoid, like a standard screw thread. It should have flat top and bottom crests, and angled sides. It looks like the sample code above calls the flat sections "A" and "D" and the peak of the thread is at "C". The root of the thread is at "E". I need to be able to control the sizes of the A,C,D, and E. Maybe think of it as a simplified V thread, with a flat top and flat root. The height of the profile should be the same as the pitch.

*   **Performance:** I want the thread to be generated as a single, solid polyhedron. The sample code seems to achieve that but doesn't seem to be using best practices. I'm aiming for something that renders quickly, so the most efficient polyhedron generation is key. I will be using this in `difference()` operations, and want to minimize render time in those contexts.

*  **Flexibility:** I'd like to be able to adjust the resolution of the thread with the `$fn` variable like in the sample code, but don't want it to be baked into the function (e.g. always using 16 sides if `$fn` is not set). The number of polygons should be settable when I call the function and can default to a reasonable value.

*   **Endcaps:** The threads should have endcaps for proper solid model generation. The example code does this, but I'd like the endcaps to be flush (not extend outside the thread diameter).

So, to summarize, I'd like a set of OpenSCAD functions/modules that generate threads based on diameter, pitch, height, and the trapezoidal profile. Also, these should be fast rendering and controllable through `$fn` as well as parameters. Please include the generated code for the main module, and any helper functions or modules used. It would be great to have that in a single file to keep it simple.

I need a parametric OpenSCAD design for a customizable linear bearing. I want to be able to specify the height, outside diameter, and inner diameter of the bearing, as well as the thickness of the shell. It should also include a tolerance setting that I can adjust to account for printer variations or material shrinkage.

I'd like an option to have the bearing open on the top and bottom, or closed. Also, I need to be able to optionally add secure rings at both ends of the bearing. This would involve setting the thickness of these rings, and the distance they are from the top and bottom of the bearing.

I'm envisioning this being used as a replacement for standard linear bearings like LM8UU or LM10UU, so it needs to be robust.

The design will essentially be a cylinder with another cylinder removed from its core, with additional features for structural integrity and secure rings. It should have a simple, relatively smooth outer shape. The core should have four intersecting cuts made to ensure smooth travel of the metal rods used with standard linear bearings.

For the code, can you make sure that it's easy to use with the OpenSCAD customizer?

Could you use the `BOSL2` library for this design?

Hey there, I'm looking to design a wall mount for some game controllers, specifically two 8bitdo SNES-style Bluetooth controllers, but I want it to be adjustable so it can hold other similar controllers. I've included the code I was working from and a description of what I wanted to change.

Basically, I need a wall-mounted base with two "arms" that stick out to hold the controllers. The base should have mounting holes, probably two. The arms should be adjustable, so I can customize the spacing, height, and depth for different controller sizes. I want the arms to have a bit of a lip or curved edge to help keep the controllers in place, without being too bulky. Also, I'd like an optional brace between the arms for added stability. I'm using OpenSCAD. It looks like the code I included was using a simple cube and cylinder approach, but I'm not married to that, feel free to approach it however you see fit.

Specifically, I need these parameters adjustable:

*   **`mount_height`**: Height of the wall mount base.
*   **`mount_width`**: Width of the wall mount base.
*  **`mount_thickness`**: Thickness of the wall mount base
*   **`mount_hole_diameter`**: Diameter of the mounting holes.
*   **`mount_hole_separation`**: Distance between the mounting holes (set to zero for one hole).
*   **`controller_arm_height`**: Vertical height of the controller arms.
*   **`controller_arm_thickness`**: Thickness of the controller arms.
*   **`controller_arm_depth`**: Depth of the controller arms and lip.
*   **`controller_arm_one_distance`**: Distance from the wall to the inside edge of the first arm lip.
*   **`controller_arm_two_distance`**: Distance from the wall to the outside edge of the second arm lip; This should be the sum of arm\_one distance, the depth of the arms, and any gap between the arm and the controller.
*  **`controller_arm_separation`**: Distance between controller arms. Set to zero if one arm, or set it to (mount_width-controller_arm\_thickness)/2 for two arms with the arms on either end of the mount.
*   **`controller_arm_brace`**: A boolean to enable/disable the brace between the arms.

I'm trying to keep the design simple but functional. The arms should have a curve to help retain the controller but not get in the way or take too much space. I don't want any of the mount or arms to extend further than they need to.

Could you generate the OpenSCAD file(s) for this? Thanks in advance!

Hey, I need a custom clip-on label designed in OpenSCAD. I've got this specific design in mind and I'd like it to be fully parametric so I can easily tweak it later.

Basically, it's a label with a rounded-rectangle main body that has a clip on the back to attach it to an IKEA DRONA box. I also want a small grip on the clip to help get it on and off. Here are the dimensions I'm envisioning, but I want them all to be customizable as parameters:

*   **Label:**
    *   `labelX`: Length of the label.
    *   `labelY`: Height of the label.
    *   `labelZ`: Thickness of the label.
    *   `labelR`: Radius of the rounded corners of the label.
*   **Clip:**
    *   `clipX`: Length of the clip.
    *   `clipY`: Height of the clip.
    *   `clipGap`: Width of the cutout on the clip that makes it flexible.
    *   `clipZ`: Thickness of the clip.
*   **Grip:**
    *   `gripX`: Length of the grip.
    *   `gripY`: Height of the grip.
    *   `gripZ`: Thickness of the grip.

The clip should be centered horizontally behind the main label. The gap in the clip should have a small, thin part on the bottom, so that it 'grips' the DRONA fabric. The grip should be towards the bottom of the clip, centered horizontally and a small amount from the edge on the top of the clip. It should also be half on the top of the clip and half on the backside.  All of this should be combined into one solid object.

Can you generate the OpenSCAD code for me? It would be great if it was well-commented for future reference. I'm also using some of the libraries: specifically BOSL2, so make sure those are included in the design.

I'm looking to create a fractal design based on the collage theorem, and I'd like to be able to control some of the transformations applied. Specifically, I want to start with a base shape and then recursively apply two transformations to it, generating a fractal. I'd like to have a few different options for the base shape, including a cube, a hexagonal prism, and a snowflake-like shape. Additionally I want to be able to control the symmetry of the fractal, with options for 2 to 8 fold symmetry.

Here's a breakdown of what I'm looking for in the OpenSCAD file:

**General Parameters:**

*   `part`: A drop-down menu to select the base shape. Options should be "Cube", "Hexagonal Prism", and "Snow Flake".
*   `nfold`: A drop-down menu to control the rotational symmetry, with options from 2 to 8 (e.g. 2, 3, 4, 5, 6, 7, 8).
*   `radius`: A slider to control the overall size of the fractal, ranging from 5 to 50.
*   `height`: A slider to control the thickness of the fractal elements, ranging from 1 to 5.
*  `level`: A slider to control the number of recursive levels for the fractal, ranging from 0 to 5.

**Transformation 1 Parameters:**

*   `xscaleone`: A slider to control the x-axis scaling factor for the first transformation, ranging from 0.1 to 0.9.
*   `yscaleone`: A slider to control the y-axis scaling factor for the first transformation, ranging from 0.1 to 0.9.
*   `shiftone`: A slider to control the y-axis shift for the first transformation, ranging from 0 to 2.

**Transformation 2 Parameters:**

*   `xscaletwo`: A slider to control the x-axis scaling factor for the second transformation, ranging from 0.1 to 0.9.
*   `yscaletwo`: A slider to control the y-axis scaling factor for the second transformation, ranging from 0.1 to 0.9.
*   `shifttwo`: A slider to control the y-axis shift for the second transformation, ranging from 0 to 2.

I'd also like the transformations to also scale in the z direction, but I don't need any control over these - they should always be 1.

The core idea is to create a recursive function that applies these two transformations, and rotates the whole structure based on the specified symmetry to generate the fractal. The base shape should be the same size as the fractal at level 0.

I'd prefer a single `.scad` file for this design. Could you generate the code for this?

Hey, I'd like to get a parametric OpenSCAD design for a battery holder, specifically for 1S LiPo batteries like the ones used in the Blade Nano QX quadcopter. I’ve designed something similar already, and I think I’ve got the basic idea of what I want.

Here’s the core idea: it needs to hold a variable number of these small LiPo batteries, and the slots should allow the batteries to be inserted in either direction. This is so when I pull out a discharged battery, I can put it back in the organizer in the opposite way to keep track of which ones are charged. The holder should also have an optional slot to fit a small USB LiPo charger.

The batteries are roughly 12.8mm wide and 5.7mm long, with a connector that adds about 2.2mm to the length, so, about 7.9mm. And the batteries are about 8mm thick.

I’m thinking the holder slots should have an outer size that provides some extra room. A good starting point is to add a 2mm wall thickness all around, so about 12.8+4mm wide, and 5.7+2.2+4mm long for the main battery compartment (with the walls). Then, the space for the battery itself should be a little more than 12.8mm by 5.7+2.2mm. So maybe like 13mm x 8mm should give the battery a little wiggle room. The depth for the compartment should be around 8mm, the same height as the battery, but I'd like it to have a bit extra depth for support at about 9mm deep (8mm for battery and 1mm bottom). I also want a circular hole through each of the battery holders. Maybe make it 4mm diameter.

The USB charger slot should be around 4.6mm wide and 12.2mm long, also about 9mm deep.

So, to summarize the key things:

*   Parametric number of battery slots (e.g., one to 30)
*   Optional USB charger slot.
*   Battery slots allow insertion in either direction.
*   Clearance for the battery + connector
*   Circular hole through each battery slot.

For the OpenSCAD file, could you set up parameters for:

*   The width and length of the battery (both with and without the connector)
*   The wall thickness
*   The total depth of the battery holder and the extra depth for the battery compartment.
*   The diameter of the hole
*   The width and length of the USB charger slot.
*   The number of battery slots
*   A boolean to enable/disable the USB slot

I don't need any external libraries for this.

Thanks!

I need help designing a parametric broom holder that latches. I've been using a design I found online, but it has a few limitations and I'd like to start with a clean slate using a parametric approach.

Here's what I need in the design:

*   **Broom Diameter:** The holder needs to accommodate various broom handle diameters. I'll need a parameter for `broom_diameter`.
*   **Hinge Height:** The overall height of the hinge mechanism should be adjustable with a `hinge_height` parameter.
*   **Wall Offset:** I need a way to control how far the broom handle sits from the wall, with a `wall_offset` parameter. This needs to have a minimum distance (as noted in the previous code) so that it doesn't conflict with the rest of the design.
*   **Vertical Clearance:** There needs to be a small gap, defined by the `vertical_clearance` parameter, where the layers break to make it printable.
*   **Extruded Width:** An `extruded_width` parameter should control for my printer's extrusion width.
*   **Filament Passes:**  The `num_filament_passes` parameter should control how many passes of filament are used for the hinge holes and related parts. The rest of the model should be roughly double this.
*   **First Layer Height:** I need a `first_layer_height` parameter, for fine tuning. It can be used for an inset on the first layer so it can be squished without a lip, but this should be optional and off by default.
*   **Hinge Pin Hole Diameter:** A `hinge_pin_hole_diameter` parameter for the holes where the hinge pins go.
*  **Hinge Clearance:** Parameter `hinge_clearance` for space around hinge parts
*   **Mount Screw Diameter:** The diameter of the mounting holes needs to be adjustable with `mount_screw_diameter`.
*   **Mount Screw Countersunk Depth:** I need a `mount_screw_countersunk_depth` parameter for countersinking the mounting holes.
*   **Mount Screw Counterbore Diameter:** I need an option for either counterboring or countersinking. A `mount_screw_counterbore_diameter` parameter that defaults to 0 to indicate countersinking.
*   **First Layer Inset:**  There should be an option to inset the first layer (similar to the original design) but it should be disabled by default, with an `inset_first_layer` boolean parameter.

The design should be split into two mirror-imaged latching arms and a base mount. It needs to use arcs and circles in the hinge design, similar to the provided SCAD file. The design should also include the mounting holes as specified. The mount and the two arms should all use the `vertical_clearance` appropriately.

I don't need any additional libraries; everything can be designed in basic OpenSCAD, just using the standard primitives and hull function. I'm not expecting the code to be optimized for compile speed. I'd like the final assembled design to appear correctly including the broom, and it should show a cross-section if a `show_cross_section` variable is set. I hope this makes sense!

Hey there! I'm looking to create a customizable coin design for a CoderDojo group. I've got some basic ideas, but need help turning them into a parametric OpenSCAD file.

Essentially, the coin should have a circular base with a raised "logo" on top. The "logo" is a stylized design with two overlapping circles connected by a "1" and a "0" on either side.

Here's what I envision for the parameters:

*   **`width`**: The overall diameter of the coin (in mm).
*   **`height`**: The total height of the coin (in mm).
*   **`border`**: The width of the border line around the white portion (in mm). This should affect the size of the overlapping circles.
*   **`font`**: The font used for the "1" and "0" characters. I'd like to be able to customize this.

The base of the coin should be a simple cylinder. The "logo" portion should consist of:
*   Two circles that overlap on a midplane, forming a "figure eight" shape. The circles should be tangent with the circular border.
*   A raised "1" and a raised "0" on opposing sides of the figure eight.
*   The "1" should be engraved in the white part of the circle base, and the "0" should be raised above the gray part.

I think that should do it. Ideally, the model should be easily printable and well-suited for use as a teaching tool for more advanced students interested in OpenSCAD. I'm hoping the code will be clean and readable. Could you provide that?

// font for numbers

Okay, I'm looking to create a pen holder, and I really like the look of the "Dragon penholder" design I saw on Thingiverse. It uses a phyllotaxis pattern to create a really cool surface texture, and I’d like to be able to customize it to fit my specific needs.

Here’s what I’m envisioning:

The basic form should be a hollow cylinder, with a customizable radius and height. The walls of the cylinder will be covered with a series of features arranged in a phyllotaxis pattern. The user should be able to control the following:

1.  **Phyllotaxis Angle:** I want to be able to adjust the angle used in the phyllotaxis calculation – the default seems to be 137.51 degrees, but I'd like to be able to modify that.

2.  **Pattern Types:** The design uses two different element patterns: “bulbs” and “spikes”. I would want to be able to choose which type of pattern is used as the primary ("pattern1") and which one is used as the secondary ("pattern2").

3.  **Secondary Pattern Frequency:** I’d like to be able to set how often the secondary pattern appears (e.g., every 3 steps).

4.  **Spike Scaling:** If spikes are used, they should be scaled with a factor – so I can control how long they are.

5.  **Bulb Customization:** For the bulbs, I want to be able to choose a decoration at the top. I’d like options for a hole, a small sphere (ball), or a flat top.

6.  **Cylinder Dimensions:** I need to be able to control the overall height and the base radius of the main cylindrical structure, as well as the thickness of the base. Also I'd like to be able to specify if the cylinder should be straight or slightly tapered.

7.  **Resolution:** The resolution of the curves and spheres should be customizable.

I am not looking for any specific libraries. It seems like this design can be achieved through base OpenSCAD functions alone. I don't think any external libraries should be required.

So, to summarize, I need a parametric OpenSCAD design for a pen holder with a phyllotaxis-based textured surface. It should allow me to control the phyllotaxis angle, the two different feature types, how frequently the second type is used, the spike scaling, the bulb decoration type, the overall cylinder dimensions and the rendering resolution. I'm excited to see what you can do!

Hi there,

I'm looking for an OpenSCAD design for a spool holder, specifically one that acts as a hook, allowing for easy spool changes on a wall-mounted rod. I saw a design like this online but it wasn't available as a printable file, so I'd like to create a parametric version. I've attached the SCAD file of a design I'm currently using, but it's a bit clunky and I would like a new version from scratch that takes the following points into consideration:

*   **Core Functionality:** The design should consist of two main parts: a section that hooks onto a cylindrical rod (like a wall-mounted bar) and a section that supports the spool itself.
*   **Rod and Spool Dimensions:** These should be parametric. I'll need to specify:
    *   `rod_tube_diameter`: The diameter of the rod the hook will attach to.
    *   `spool_tube_diameter`: The inner diameter of the spool's core.
    *   `spool_height`: The width (height) of the spool to be supported.
*   **Overall Length:** I need to be able to control the overall length of the hook. So a variable for `length` should exist.
*  **Pin Option:** I want a parameter to optionally include a pin on the spool end for connecting multiple hooks together. I'd like this option to be a simple boolean (or equivalent) to enable/disable the pin.
*   **Construction:** The hook should be constructed as a "hollow" design, meaning the spool side should have a tube with an open end for the spool to sit on.
*   **Strength:** The base connection to the hook and the spool support tube should have some additional structure and/or fillets to reinforce it.
*   **Parametric Design:** Everything should be parametric. I want to easily change the diameters, lengths, height, etc. to make this work for different setups.
*   **Additional parameters:** I want a `thickness` parameter that controls the overall thickness of the print. I need also an `height` parameter that should control the total vertical height of the hook and the spool support tube.

I'd like the design to be as clean and efficient as possible. I don't mind if some math functions are used to calculate the thickness of the hook. I expect to be able to set parameters like `rod_tube_diameter = 28;`, `spool_tube_diameter = 30;` `spool_height = 80;` and `length = 160;` to generate the hook. Also it is important to be able to toggle the pin with a `pin = "Yes";` or `pin = "No";` parameter.

I don't require any special libraries. Plain OpenSCAD should be fine.

Thanks for your help!
