Hi, I'm looking to get some help creating a parametric gimbal mount in OpenSCAD. I have a design in mind that I'd like to be able to customize easily for different sized objects. I want it to essentially hold an object using two pivot points that allow it to spin.

Here are the key parameters I want to control:

*   **Gimbal Distance:** The distance between the two pivot points.
*   **Pivot Throat:** The inside width clearance distance around the object being mounted.
*   **Pivot Diameter:** The diameter of the pivot points themselves.
*   **Thickness:** The overall thickness of the gimbal material.
*   **Height:** The overall height of the gimbal part.
*   **Resolutions:** I'll need to control the resolution of the pivot point circles (`iresPiv`), larger curves (`iresBig`), smaller curves (`iresSmall`), and round corners (`iresRnd`).

I'd like the design to include the following features:

*   A central, open area to hold the rotating object, defined by the `PivotThroat`.
*   Two pivot points, created by cutouts on either side, centered at the `GimbalDistance` and `Height`.
*   Round corners for aesthetics and strength around the edges.
*   The whole thing should be generated by subtracting shapes from a basic cube for the main structure.
*   The `Indent` module should create the indents that accept the pivoting part of a rotating object.

I'm aware that my current design has limitations for small values of `PivotThroat` and `GimbalDistance`, so I'd really appreciate it if the new design could handle a wider range of these values without breaking. I'd prefer that you create everything from scratch rather than trying to modify my existing code, which I've provided below.

Also, I don't want to have to manually define all of those cutting variables, please try and calculate those from the main parameters, I believe that it should be possible.

Thanks a lot, let me know if you have any questions.

I'm looking to create a custom audio reflector box for my Yaesu FT-817 radio. I often use it in portable setups, and the speaker on top can be difficult to hear. I've been using my hand to reflect the audio forward, and I think a small box that clips onto the front edge would be perfect.

The box should have a curved reflector surface to direct the sound forward. I’d like to be able to adjust some parameters to fit different situations, so it needs to be parametric. Here's what I have in mind:

*   **Overall Shape:** The box will be roughly rectangular, but with a curved face that acts as the reflector.
*   **Opening Width:** This is the width of the opening where the radio speaker will be.  I need to be able to set this as a parameter, `opening_width`.
*   **Wall Thickness:** The thickness of the plastic should be adjustable with a `wall` parameter, so I can tweak it for printing.
*  **Front Margin to Curve:** A `front_to_curve` parameter to control how far the box extends before the curve starts.
*   **External Height:** I want to be able to set the external height of the box using a parameter `h`.
*   **Minimum Length:** There should be a minimum length parameter, `minlen`. The box can be extended longer to accommodate my battery and tuner on top.

Essentially, it needs to:

1.  Create a rectangular box.
2.  Remove a rectangular opening from the front to expose the speaker.
3.  Add a curved surface starting at the front margin point to act as a reflector.
4.  Allow me to set `opening_width`, `wall`, `front_to_curve`, `h`, and `minlen` as parameters.
5. Use rounded edges and corners for a smooth and robust design.

The goal is a simple functional design; audio quality isn't a priority. I'm not sure how much the curvature needs to be; I'm happy to experiment with that on my end and tweak parameters to get it just right.

Could you generate the OpenSCAD code for me? I do not need any libraries, just a single .scad file that's fully self-contained.

Hey, I'm looking to create a Q-tip holder that looks like a cloud. I've got some specific ideas in mind.

Essentially, I want a container that's made from a combination of cylinders and a rectangular box to give that fluffy, cloud-like shape. I'd like the design to be parametric so I can tweak the size and shape as needed. I'd also really like an optional lid for it, and would want some of the dimensions to be customizable in OpenSCAD's customizer.

Here's a breakdown of what I'm thinking:

**Overall Structure:**

*   The main body will be a union of several cylinders and a rectangular prism, positioned to form a cloud shape.
*   There should be a base to the container.
*   An optional lid should fit snugly over the base.

**Parametric Variables:**

*   `with_cover`: A boolean variable (1 for yes, 0 for no) to enable or disable the lid.
*   `qtip_length`:  The standard length of a Q-tip, probably 80mm.
*  `total_height`: Total height of the base of the Q-tip holder. I'd like to be able to set this between 30 and 100mm.
*   `floor_height`:  The thickness of the base floor, range between 0.1 and 5 mm.
*   `wall_thickness`: The thickness of the container walls, range between 0.1 and 5 mm.
*   `xy_size_factor`:  A multiplier for the x and y dimensions, allowing me to scale the cloud's overall size, with a range between 0.1 and 3.0.
*   `cover_lip_height`: The height of the lip that is shared by both lid and base. This should be adjustable, maybe between 1 and 30 mm.
*   `cover_fit_buffer`: A small buffer to control the fit between the base and lid, maybe from 0.1 to 3 mm.
*   `cover_lip_thickness`: Wall thickness of the lid's lip, probably similar to `wall_thickness`, can be zero.

**Cloud Details:**

*   I'm imagining a group of cylinders that vary in size and position. Here are the initial cylinder parameters, but I'd like to be able to adjust these parameters as a set and by the individual cylinder:
   *   Cylinder 1: Radius 20mm, X-position 50mm, Y-position 0mm
   *   Cylinder 2: Radius 25mm, X-position 35mm, Y-position 30mm
   *   Cylinder 3: Radius 28mm, X-position 0mm, Y-position 40mm
   *   Cylinder 4: Radius 18mm, X-position -32mm, Y-position 26mm
   *   Cylinder 5: Radius 24mm, X-position -50mm, Y-position 4mm
*   Also, I would like to add a rectangular prism.
    *   Box: width 100mm, depth 40mm, x_move -50mm, y_move -20mm.

**Lid:**

*   The lid should be designed to fit the top of the cloud shape, mirrored and inverted so it covers the base.
*   It should have a lip that fits inside the base to create a secure fit, with a slight buffer between the base and lid for tolerance. The lip should extend down from the lid by `cover_lip_height`.
*   The height of the lid should be calculated automatically based on the `qtip_length`, `total_height`, and `floor_height`.

I think that's all of the main aspects. I really appreciate you assisting me with this! I would like it all in a single file, but I'm flexible if you think there's a better way to organize things. I'd like the $fn to be set to 200, but I don't need a variable for that.

Hey, I'm looking to design a customizable seven-segment display for my fridge. I've seen some cool ones online but nothing quite matches what I'm after, and they can be really expensive to buy. I'd like to be able to print one, and I think it should be parametric so I can easily tweak the dimensions.

Here's what I'm thinking:

**Overall Structure:**

*   The design should be a single digit seven-segment display.
*   It needs a base with an external margin around the digit itself, and it should be easy to control how big that margin is.
*   I'd like to be able to set the depth of the digit area, which will be sort of a recessed area where the segments sit, and a few layers on top of that.
*   I want to be able to control the thickness of the layers used for the screen and any light diffusers. There should be a way to control the minimum layer thickness, and have options for single, double, and triple layers for both the main screen and extra light diffusion layers.
*   There should be a final cover over the digit.
*   The whole thing should be built using OpenSCAD.

**Segments:**

*   I want to be able to set the length and width of each segment individually.
*   The segment style should be fairly simple; for now I don't need rounded or octagonal segments, just plain rectangular blocks.

**LEDs:**

*   I want to incorporate LEDs into this, rather than just printing solid segments, so there need to be holes for standard LED sizes. I’d like to be able to choose between 1.8mm SMD, 3mm, 5mm, and 8mm LEDs.
*   The LED holes should have adjustable tolerances for a snug fit. I'd like to be able to control how tight the fit is.
*   There should also be an option for controlling how deep the LED holes are and how deep a glue area should be around each LED.
*   The glue area should also have its tightness controlled by a parameter.

**Build Plate:**

*   I would need to use a library like utils/build\_plate.scad (I won't provide it, but I need the functionality), to specify build plate size for display. I'm assuming it will have common options like "Replicator 2", "Replicator", "Thingomatic", and a manual setting where I can specify the plate dimensions.

**Libraries**
*   I want to use the `write/Write.scad` library (again, I won't provide it, but it should be used).

So, basically, I need a fully parametric seven-segment display with LED holes, controllable layer heights, tolerances, and margins. I'd really appreciate if you could create the code for this!

Hey, I'm looking to design a replacement sprinkle nozzle for my watering can, and I'd like to use OpenSCAD to make it customizable. I have some specific ideas about the shape and spray pattern, and I was hoping you could help me generate the necessary .scad files.

Here's what I'm thinking:

**Overall Shape:**

The nozzle will have a main cone section attached to a cylindrical neck. The main cone shape is important and I want to be able to tweak it using a few parameters. I'd like to define a diameter (`cone_dia`) and a length (`cone_len`) as a starting point for the cone, but I also want to be able to adjust how much of the cone's edge is "cut off" or beveled using a parameter I'll call `cone_bevel`. This should range from 0.0 (no bevel) to something close to 1.0 for maximum bevel. The neck will have a nominal diameter (`neck_dia`) and an optional cone at its start controlled by `neck_cone`, to go from one diameter to another. Finally, the neck will have a fixed length (`neck_len`).

**Wall Thickness:**

The overall wall thickness should be controlled by a `wall` parameter, and all the features of the model should respect this.

**Spray Pattern:**

The spray is to be made of individual holes arranged in rings. The size of the holes should be controlled by `nozzle_dia`, and the radial distance between the rings of holes should be controlled by `nozzle_dist`. The holes should be "drilled" at a slight angle, like in the provided example. This way, the water spray is not just going straight out.

**Parameters Summary:**

*   `cone_dia`: Diameter of the cone (without bevel).
*   `cone_len`: Length of the cone.
*   `cone_bevel`: Controls the amount of bevel at the cone's edge.
*   `neck_dia`: Nominal diameter of the neck.
*  `neck_cone`: Additional diameter for the start of the neck cylinder.
*   `neck_len`: Length of the neck.
*   `wall`: General wall thickness.
*   `nozzle_dia`: Diameter of each nozzle opening.
*   `nozzle_dist`: Distance between rings of nozzles.

I think this covers most of what I need. I'd like to get these parameters into the OpenSCAD code. Let me know if you need any more details, or if you have any questions!

I'd like to design a customizable hammer that uses coins as the weight. The core idea is based on the mathgrrl_pennyhammer.scad file I found online, but I'd like to expand on it and make some improvements.

Specifically, I want:

1.  **Parametric Coin Support:** The design should take parameters for coin diameter and height, as well as the number of coins to use. I want to be able to easily swap out different coins for different weights.

2.  **Handle Options:**  I'd like to have a few options for the handle. One option should be a simple cylindrical handle. A second option would be a more ergonomic handle, maybe with some curves or finger grips. I'd like to be able to specify the length and thickness of the handle, regardless of handle shape.

3.  **Open/Closed Top:** Like the original design, I want an option to have an open top (coins visible) or a closed top (plastic cover).

4.  **Secure Coin Containment:** I want to ensure the coins are securely contained within the hammer head. Maybe a slight lip or indent where the coins rest, or maybe a threaded section that can be closed by a cap.

5.  **Base Thickness:** It would be nice to control the base thickness (below the coins) independently of the rest of the design.

6.  **Material Thickness:** Allow a parameter to control the material thickness throughout the design.

7.  **Render Quality:** I'd like to be able to control the render quality using `$fn`.

8. **Unit Testing:** It would be awesome if you could include some testing code that confirms the calculations being used, particularly for the coin stacks and internal geometry.

I'm not familiar with OpenSCAD libraries, so I'm assuming you will not be using any of them. Let me know if you have any questions!

Hi, I'm looking to design a hotend fan mount for my Kossel delta printer, and I need some help with the OpenSCAD code. I have an E3Dv6 hotend, a standard 40mm fan for hotend cooling, and the Mini Differential IR height sensor board v1.1 from miscsolutions. I’ve seen some designs out there but I want something more parametric so it’s easier to tweak and adapt.

Here's what I'm thinking, and hopefully you can turn it into some parametric code:

**General Structure**

*   The mount needs to attach to the effector using three mounting holes arranged in a circle. I want to be able to define the radius of this circle as a parameter. I need to be able to also vary the radius of the mounting holes individually, for a little extra tolerance.
*   It should have a groove that fits around the E3Dv6 hotend barrel, with adjustable parameters for the barrel's radius and the height of this groove.
*   The 40mm fan should be mounted with adjustable offsets, including vertical offset, and the mounting screw hole centers should be parametric. It should have a duct or funnel to direct airflow toward the hotend.
*   A mounting flange should be included for the IR sensor board, with parametric control over the board's position relative to the nozzle and the flange thickness.

**Specific Dimensions**

I'll provide some default dimensions but, again, I want to be able to change these through parameters:

*   **Mounting Circle Radius:** The distance of each mounting hole from the center of the effector. Default to 14.5mm.
*   **IR Board Back Offset:** Distance of the back of the IR sensor board from the nozzle center. Defaults to 11.0mm for a PT100 or thermocouple setup.
*   **Hotend Barrel Radius:** Should start at around 11 mm
*   **Hotend Barrel Height:** around 26.2mm
*   **Main Height:** the total height of the main body. Default around 39mm.
*   **Groove Radius:** Around 6.1mm
*   **Groove Height:** Around 5.8mm
*    **Fan offset:** 18mm
*   **Nozzle Height:** 58.1mm from the effector.
*   **IR Flange Thickness:** 6mm.
*   **IR Board Fixing Centers:** 21.11 - 2.70mm
*   **IR Board Fixing Offset:** IRBoardBackOffset + 1.01mm
*   **IR Board Fixing Height:** nozzleHeight - 14.9 - 1.5
*   **IR Board Width:** 24.6mm
*   **IR Cutout Width:** 12.5mm
*   **M3 Screw Radius:** Standard M3 radius (see config below), but should be a parameter.
*   **M3 Vertical Extra Radius:** 0mm default, for a little extra wiggle room around the m3 vertical holes
*   **Fan Vertical Offset:** 0mm
*   **Fan Screw Spacing:** 32mm squares
*   **Overlap:** 0.01mm

**Additional Considerations**

*   I want to be able to easily adjust all these parameters in a configuration file, so that I don't have to edit code every time.
*  I will also want to add a second 40mm fan, but I don't need that right away, though I might want to leave some space for mounting that later on.
*   Make sure it's designed with good tolerances in mind so that the parts fit together well after printing.
*   I'd like to use the standard metric screw dimensions from something like a "configuration.scad" file (example attached) which could be imported by the main file.

**configuration.scad:**
```
// Increase this if your slicer or printer make holes too tight.
extra_radius = 0.1;

// OD = outside diameter, corner to corner.
m3_nut_od = 6.1;
m3_nut_radius = m3_nut_od/2 + 0.2 + extra_radius;
m3_washer_radius = 3.5 + extra_radius;

// Major diameter of metric 3mm thread.
m3_major = 2.85;
m3_radius = m3_major/2 + extra_radius;
m3_wide_radius = m3_major/2 + extra_radius + 0.2;

// NEMA17 stepper motors.
motor_shaft_diameter = 5;
motor_shaft_radius = motor_shaft_diameter/2 + extra_radius;

// Frame brackets. M3x8mm screws work best with 3.6 mm brackets.
thickness = 3.6;

// OpenBeam or Misumi. Currently only 15x15 mm, but there is a plan
// to make models more parametric and allow 20x20 mm in the future.
extrusionV = 20;
extrusionH = 15;

// Placement for the NEMA17 stepper motors.
motor_offset = 44 - 7.5 + extrusionV/2;
motor_length = 47;
```
Can you help me generate this? Thanks!

I'm working on an adapter to use M12 (S-mount) lenses with 2/3" sensors. The problem is that these lenses often have a shorter flange focal distance than what's needed for a 2/3" sensor. I have an existing, non-parametric design based on an STL (that I've included in `m12.scad`), but I need a parametric OpenSCAD version that lets me adjust the key dimensions.

Here's what I need:

*   **Parametric Design:** The design should be fully parametric, allowing easy modification of dimensions like height, inner and outer diameters, and the thickness of various parts.
*   **M12 Thread:** It should have a precisely modeled M12x0.75 thread for mounting the lens. I want to be able to specify the length of the threaded portion. It would be great if you could use a library for the thread generation rather than modeling it manually.
*   **2/3" Sensor Interface:** On the sensor side, it should have a flat circular surface for the 2/3" sensor. I need to be able to specify the diameter of this surface and the thickness of the material behind it.
*   **Spacer:** I need a central cylindrical spacer to add extra distance between the lens and sensor. I need parameters to adjust both the height and diameter of this spacer.
*   **Simple Cylindrical Base:** The simplest design would involve the M12 thread extending out of a cylinder, which is attached to the 2/3" sensor surface via the spacer.
*   **Libraries:** I think it would be good to use the BOLTS library for the M12 threads, and, since there are other threaded optical bits, perhaps using the Optica library as well might be helpful for other projects in the future.

I'm primarily concerned with getting accurate dimensions and the ability to easily modify them. I'm not particularly worried about how it looks visually, just as long as it's functional. It would be ideal if I could specify all key dimensions as named parameters. Could you please generate the necessary OpenSCAD file(s)?

I'd like to design a wire clamp that can be 3D printed. I have a concept in mind that's similar to the one in the Thingiverse link, but I need to make it parametric so I can adjust the dimensions for different wire sizes and mounting needs. The basic idea is a hinged clamp that closes around a wire or pole.

Here's a breakdown of the features I'd like to control:

*   **Overall Dimensions:**
    *   `clamp_height`: The total height of the clamp.
    *   `clamp_length`: The length of the clamp, along the axis the wire passes through.
    *  `clamp_width`:  The width of the clamp, which also dictates the diameter of the pole it clamps.
    *   `clamp_gap_depth`: The length of the slot or cut that fits into the mounting plate/surface.

*   **Wire Holding Area:**
    *   `wire_diam`: The diameter of the wire or pole that the clamp will hold.

*   **Mounting Plate Connection:**
    *   `plate_thickness`: The thickness of the plate that the clamp will slot into.
    *   `slot_gap`: The width of the slot in the clamp that receives the mounting plate
    *   The slot should be cut into the clamp along the length.

*   **Screw Mounting:**
    *   `screw_hole_diam`: The diameter of the screw hole for mounting the clamp.
    *   `screw_hole_depth`: The depth of the screw hole into the part.
    *  `screw_recess_diam`: The diameter of the countersunk recess for the screw head.
    *   `nut_type`: The number of sides on a nut to be cut out (4, 5, or 6).

*   **Angled Tabs**
    * `enable_angledtabs` Boolean to enable or disable angled tabs that extend on the side to be screwed.
    * `wiretab_angle`: Sets the angle of the tabs relative to the center of the wire being clamped.

*   **Ledge**
    * `enable_ledge` Boolean to enable or disable a ledge that partially encompasses the wire being clamped.

I'd like the clamp to have a split design with a hinge on one side, and the screw on the other. The clamp should have an area cut out to fit over the wire. The slot for the mounting plate should pass through the entire piece, on the side opposite the hinge.

The design should consist of a single main module, and other submodules or functions as needed for readability.
I'd like to use standard OpenSCAD primitives wherever possible and would appreciate it if you could generate a completely self-contained set of .scad files, without relying on external libraries.

I need an OpenSCAD design for a parametric spool holder. I'm using a Creator Pro printer, and the stock spool holder is too large for most of my spools. I'd like something that can adjust to different spool core diameters, core depths, and offsets from the center, and it needs to be printable without supports.

The design should have these features:

*   **Core Diameter:** It needs to accommodate spools with different inner core diameters. This should be a parameter.
*   **Core Offset:** Some spools have their core offset from the center of the spool. The design must account for that offset, as a parameter.
*   **Core Depth:** The design should work with spools of varying core depth. This should be adjustable too.
*   **Percentage:** The design must account for how much of the spool that is printed, to allow for very small spools.
*   **Support Structures:** The design should incorporate a small notch, a tab, and a hang to prevent the spool from falling off, and to stabilize it.
*   **Printability:** The design should be optimized to print without supports. I'd prefer to avoid angles that require support material, and generally prefer cylinders.

I've attached an example .scad file (spool-x04.scad) that shows how I'm currently thinking about this, but please don't feel bound to it. I'd rather you create something more robust.

For the libraries, please only use the BOSL2 library, if needed. I'd prefer you not use libraries if it is not required.

I need to design a jig for soldering WS2812B LEDs, those little individually addressable ones, and I want it to be parametric so I can easily adjust the spacing between the LEDs. I've got a basic idea of what it should look like, but I need help making it a proper OpenSCAD file.

The jig will essentially be a base with recesses to hold the LEDs in place for soldering. The core parameter will be `gap`, which will control the distance between the centers of adjacent LEDs. I'd like to easily adjust it, maybe with a default of 70mm and a reasonable range like 10 to 150 mm.

Here's how I envision the structure:

1.  **Base:** A cylindrical base with a flat top and bottom to provide stability and something to grip when placing the LEDs. Maybe use a cylinder for the general shape, then cut away the bulk of the base to make it lighter and give it a mounting surface of sorts (e.g. using a cube for the cutting operation).
2.  **LED Holes:** These are the recesses that the LEDs will sit in. Each LED hole will need a main circular pocket (like a small cylinder cut out) to hold the LED body itself, and a smaller rectangular slot underneath it to allow for the solder pads. The LED holder needs to have a small piece cut out of the side to allow for wires to be easily attached (a small extruded polygon should work well). I want three LED holders in total, placed such that one is in the center of the jig base, and the other two are placed at +/- `gap` offset along an axis.
3. **Parametric Design**: The entire design should be driven by the `gap` parameter, so I can easily make jigs with different spacing between LEDs.

The dimensions I have in mind for the LED hole are as follows:
    * The cylinder for the LED body itself is 5.25 mm radius and 4mm deep
    * There is an underlying rectangular cut out that is 8mm x 5.5mm x 5.5 mm.
    * The little wire slot should be a small extrusion 1 mm high, with a polyon base that is approximately 7mm tall (max) and 4mm wide at the base.

Could you generate an OpenSCAD file based on this description? I would like the code to be fully parametric in terms of `gap`, and have reasonable dimensions for the jig. No need for me to import anything, it should just be one file, with everything inside.

I'd like to design a customizable coin or token that can be personalized with an image, and have a circular or square outline. I've seen some examples, and I'm thinking of a design where a lithophane of the image is the central part, and it's surrounded by a solid border to make it a sturdy coin shape.  Could you generate an OpenSCAD file that does this?

Here's what I'd like to be able to adjust:

*   **Image Input:** I need to be able to specify a grayscale image file, similar to the `image-surface.dat` example I've seen. The image should be stretched to fit within the specified dimensions. I know that the image needs to be prepped to not be backwards if it has letters.
*   **Shape:** I need a simple boolean parameter to choose between a circular or square coin shape.
*   **Overall Size:** A parameter to define the overall size (diameter for a circle, side length for a square).
*   **Layer Height:**  A parameter for the 3D printer layer height.
*   **Number of Layers:** A parameter to specify the number of layers for the lithophane part of the coin. There should also be a base that is two layers thick, beneath the lithophane.
*   **Border Width:** The width of the solid border around the lithophane.
*   **Border Thickness:** The thickness of the solid border of the coin.
*   **Ring Hole:** For this first iteration I'd also like a ring hole, though for a square coin this will probably go at one of the corners.  I don't need a location parameter for the ring hole, just a single size parameter for it and a sensible placement.
    *  I'd like this parameter to be called `ring_hole`.
    * I would like this to be a simple cylinder that is subtracted out, not a fancy loop.

I'm looking for a single file to generate the whole design. Could you handle that for me?

I'm looking to design a servo mount for an OB1.4 3D printer carriage, intended for use with automatic bed leveling. I'd like the design to be parametric so I can adjust it for different servos and carriage mounting positions in the future.

Specifically, the mount needs to have two main parts: a servo holder and a mounting structure that attaches to the carriage.

The servo holder part should:
- Be designed to hold a servo with a configurable length, width, and height. There should also be a separate, thinner mount for the servo.
- Have screw holes for mounting the servo to the mount, with configurable positions relative to the center of the servo mount.
- Have the servo mount offset from the actual servo by a given distance.

The mounting structure needs to:
- Attach to the carriage using a cylinder that passes through a hole in the carriage. The cylinder has a defined diameter and length.
- Have a main cylinder coming off the back of the servo to join the mounting cylinder. This cylinder is also configurable by diameter.
- Have screw holes for attaching the servo mount to the main cylinder. These should be positioned such that they line up with the holes on the servo holder portion, and have a defined diameter and length.
- Have a hole through the mounting cylinder for a mounting bolt.

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

- `servo_length`, `servo_width`, `servo_height`: Dimensions of the main servo body.
- `servo_mount_length`, `servo_mount_width`, `servo_mount_height`: Dimensions of the servo mount
- `servo_mount_offset_z`: Height of the servo mount above the main body of the servo
- `servo_mount_screw_hole_offset`: Position of screw holes for mounting the servo relative to the center of the servo mount.
- `servo_mount_screw_hole_diameter`: Diameter of the servo mounting holes.
- `servo_mount_screw_hole_length`: Length of the servo mounting holes
- `carriage_mounting_hole_diameter`: Diameter of the hole in the carriage for mounting.
- `carriage_mounting_hole_length`: Length of the cylinder for the carriage mounting.
- `carriage_to_servo_distance`: Distance from the bottom of the carriage mounting hole to the bottom of the servo body.
- `carriage_mounting_bolt_diameter`: Diameter of the bolt used to mount the servo to the carriage.
- `carriage_mounting_bolt_length`: Length of the bolt used to mount the servo to the carriage.
- `servo_to_mount_hole_offset`: The offset between the servo and mount in the xy plane.

Could you generate an OpenSCAD file or files using best practices for parametric design? I’m fine with using existing libraries, but I’d prefer something that isn’t too difficult for beginners. I'm familiar with the basic OpenSCAD syntax, and would like to use standard libraries rather than those requiring a bunch of custom dependencies. Maybe something using the BOSL2 library would be good?

Hi there, I'm looking for an OpenSCAD design for a universal filament filter, similar to the one Creative Tools made a while back. I've found a version of it in OpenSCAD, and I'd like something along the same lines, but with a few modifications, and written from scratch if that's okay. The original version had a slot for the filament to pass through, at a 45 degree angle, and a captive hole for the filament after the slot.

Here are the core requirements:

1.  **Filament Slot:** The design should feature a 45-degree angled slot for filament entry. This is crucial for working with both 1.75mm and 3mm filaments. The slot width should be parametrically adjustable based on the filament diameter and a "slot factor" variable.
2.  **Filament Hole:** After the slot, there needs to be a captive hole to hold the filament. The hole diameter should also be parametrically adjustable based on filament diameter and should be slightly larger than the filament itself.
3.  **Filter Body:** The main body of the filter should be cylindrical, with adjustable height and width. I'd like the option to use either a rounded or flat base and top.
4. **Exit Hole:** There should be a through-hole for the filament to exit the filter.
5. **Parametric Design:** The design should be fully parametric, allowing for easy adjustments to dimensions like filter height, width, filament diameter, slot factor, and exit hole size. I’m hoping to be able to adjust the wall thickness, as well as the roundness of the top and bottom caps.

I don't really have a preference for libraries - it'd be fine to use whatever you think is best. But please specify which libraries you use.

If you have any questions or need more details, just ask! Thanks for your help.

I'd like to create a tool similar to the one I've already made, but I need it to be more flexible. My current OpenSCAD design (which I can show you if needed) uses a loop to create a series of holes with incrementally increasing diameters, both vertically and horizontally. This is great for testing screw fits, but I want to be able to customize it more easily.

Specifically, I'd like the new design to be parametric so I can change a bunch of things without having to dig into the code so much:
*   **Base Diameter:** The starting diameter of the smallest hole.
*   **Number of Holes:** How many different diameter holes will be in the test piece.
*   **Diameter Increment:** The amount the hole diameter increases with each step.
*   **Vertical Hole Height:** The length of the cylinders used for the vertical holes.
*   **Horizontal Hole Width:** The length of the cylinders used for the horizontal holes.
*   **Padding:** The spacing between each of the holes.
*   **Base Length, Base Width, and Base Height:** the dimensions for the main body of the object. I'd like this to be automatically calculated by the other values.
*   **Hole Position:** Instead of just a single line of horizontal and vertical holes, I'd like to have control over the X, Y, and Z coordinates.

It would be amazing if you could create the OpenSCAD files for this tool. I would also like to ensure all parameters have comments explaining what they control, especially regarding spacing of the holes. I'm not using any external libraries, just vanilla OpenSCAD. I need this to work on a normal desktop PC so I can't use any server-side libraries.

I need a parametric OpenSCAD model for a guitar tuning peg knob. I'd like it to have a rectangular hole through the center for the tuning peg itself, and a generally rectangular knob shape with chamfered edges.

Here's the specifics I'm thinking of:

**Hole Parameters (for the peg):**

*   `hole_x`: The length of the rectangular hole, should be adjustable in mm.
*   `hole_y`: The width of the rectangular hole, also adjustable in mm.
*   `hole_depth`: The depth of the hole (how far it goes into the knob), adjustable in mm.

**Knob Parameters:**

*   `knob_width`: The width of the main part of the knob, in mm.
*   `knob_height`: The height of the knob (how far it extends away from the peg), in mm.
*   `min_thickness`: The minimum thickness of the knob where it surrounds the hole, in mm, like the "wall" thickness.
*   `chamfer_width_pct`: The percentage of the knob width that is chamfered. A value of 0 would have no chamfer, while 0.5 would chamfer the whole width to a point.
*  `chamfer_thick_pct`:  The percentage of the knob thickness that is chamfered, similar to chamfer_width_pct but for the thickness.

**Constraints:**

*   The hole should be centered within the knob.
*   The knob height should be at least as much as the hole depth plus the minimum thickness on one side, but should still be a settable parameter.
*   The chamfers should be applied to all four long edges.
*   The output should be a single part.

I'd like the parameters to be easily adjustable using the customizer in OpenSCAD. Could you make sure to use `$fn` for controlling the fineness of any curved parts and provide a default value of 32? Also, please ensure the model uses `hull` to make the hole with rounded ends, and `difference` to remove the hole and chamfers from a basic block shape of the knob.

I'm looking for a single `.scad` file, and don't need any additional libraries.

Hey, I'm looking to get a custom stand designed for my conical centrifuge tubes. I want it to be parametric so I can adjust it for different tube sizes. Basically, it's a conical shape with a flat base. The stand needs to have a wall thickness so that it's not solid.

Here's what I have in mind for the parameters:

*   `wall`: The thickness of the stand's wall.
*   `tube_diameter`: The outer diameter of the conical tube that will sit in the holder.
*   `bottom_diameter`: The diameter of the bottom opening of the conical part of the stand.
*   `taper_height`: The height of the tapered section of the stand.
*   `overall_height`: The total height of the stand.
*   `base_diameter`: The diameter of the base of the stand.

I'd also like for the base to be hollow, which I think would save on material and print time.

Could you generate the OpenSCAD code for this? I’m thinking it will likely be one or two files, one for the main part and perhaps another for any calculations if you need them. Also, I prefer to keep the `$fn` value separate from the main design. Let me know if you have any questions!

I'd like to design a custom bike sprocket where I can specify the text on it, the size of the text, the thickness of different parts, and the overall dimensions. I also want to control the number of gear teeth. I need this to be a parametric OpenSCAD design.

Here's a breakdown of what I'm looking for:

**Text:**
*   I want to be able to specify the text displayed on the sprocket. It should wrap around the sprocket.
*   I should be able to control the text size.
*   I need to be able to control the thickness of the letters.
*   I'd like to use the "Arial Rounded MT Bold:style=Regular" font.

**Sprocket Dimensions:**
*   I need to be able to define the overall thickness of the sprocket.
*   I need to specify the radius of the inner circle (where the spokes might connect).
*   I need to define the radius of the circle where the text is placed.
*   I need to specify the radius of the outer edge of the sprocket.
*  I need to be able to define the width of the concentric rings that make up the main part of the design.

**Gear Teeth:**
*   I need to specify the number of gear teeth around the edge of the sprocket.
* The gear teeth should extend outside the outer radius.
* The gear teeth should have a similar shape to the ones shown in the attached example, with two mirrored sections that have an angled profile.

**Overall Structure:**
*   The text should be placed in the middle of the sprocket, wrapping around the center.
*   The sprocket should consist of concentric rings, with the text sitting on the inner ring.
* There should be radial supports that extend from the inner circle to the outer circle, with a gap around the center.

I'm hoping for a design that's easy to adjust, where I can change the text, dimensions, and gear tooth count. I'd like the code to be well-commented so I can understand how it all works. I don't need any libraries to do this as I understand the built-in primitives and functions in OpenSCAD.

Hi there, I'm looking to get a parametric V-groove pulley designed for 3D printing. I've seen a few designs, but I'd like to make sure mine is easily customizable. It needs to be printable in two halves, with the split being right down the middle of the bearing so the bearing is enclosed completely when the halves are glued together.

I'd like the following parameters:

*   **Bearing Diameter:** The outer diameter of the bearing that fits in the pulley (e.g., 22mm for a 608 bearing).
*   **Bearing Width:** The width of the bearing.
*  **V-Groove Depth:** The distance from the bottom of the V-groove to the top of the bearing.
*   **Wall Thickness:** The thickness of the material over the sides of the bearing.
*   **Shoulder:** How far the sides of the pulley protrude over the sides of the bearing.

Ideally the design should use the `rotate_extrude()` function to get a nice smooth circular profile. I'm not sure if it'll be required but if you feel you need to make use of a library, I prefer BOSL2, thanks. Let me know if you need any further information.

Hey, I'm working on a project inspired by Indian architecture, and I'm trying to create some sand molds for a kind of scaled-down infinite stairs castle I've been playing with. I've got a good handle on the overall concept, but I could really use some help generating the OpenSCAD files for the molds themselves.

Basically, I need two main molds: one for a pyramid and another for a mirrored set of stairs that are designed to fit onto the pyramid. The key thing is that both of these molds need to be scalable using a single variable, so that when the pyramid gets bigger, the stairs get bigger proportionally, and they always match. I also need the mold for the stairs to have a 'negative' space within, so that I can actually make the stairs from the mold. Here's a more detailed breakdown of what I'm looking for:

**Pyramid Mold:**

*   It should be a four-sided pyramid, generated by rotating a triangular side.
*   It needs to be parametric, controlled by a `scale` variable (e.g., `scale = 100`).
*   The dimensions of the pyramid base, height, and overall size should all be relative to this `scale` variable.  I'm envisioning that the pyramid base might be a scaled rectangle, and that the triangular side is constructed with a series of small rectangles in a kind of triangular shape. I do not want a simple triangular face, though.
*  The pyramid should be a "mold", and therefore, be the negative space of the pyramid that i want to cast.

**Mirrored Stairs Mold:**

*   This should create a mirrored set of stairs. So basically, a single set of stairs, mirrored across an axis.
*   Like the pyramid, it should also be parametric, tied to the same `scale` variable as the pyramid.
*   The stairs should have dimensions that make sense relative to the pyramid generated from the same scale. I'd like the stairs to look like they are climbing up one face of the pyramid.
*   The mold itself needs to be a *negative* version of the stairs, so that when you press sand into it, it creates the shape of the actual stairs, and then the stair mold should have a small offset to allow for the mold.

**General Requirements:**

*   Everything should be parametric and controlled by that single `scale` variable, so the stairs will always fit the pyramid, no matter how large or small it is.
*   I'd prefer to keep it pretty basic, using standard OpenSCAD primitives wherever possible.
*   I don't want to rely on any particular external libraries; everything should be built from scratch.

I think that's about it. I'm excited to see what you come up with!
