Hey, I'm looking for some help creating a parametric design for organ pipes in OpenSCAD. I've messed around with some designs already, and the existing code I have is pretty difficult to work with. I need a more robust solution and I think using libraries might be the best way to go. I'm hoping you can help me with this.

My idea is to create a pipe with an adjustable internal volume and several other dimensions, including the wall thickness, bottom thickness, cap height and mouth height. The pipe also needs a windsheet with a windsheet thickness and angle. The pipe has a "mouth" which is angled with a mouth angle. I want to be able to control all of these features with variables. There should also be a pipe "cap" at the top of the pipe that can be turned on or off with a boolean variable.

Here are the parameters I had in mind:

*   `wall_thickness`: Thickness of the pipe walls.
*   `cap_height`: Height of the cap section.
*   `bottom_thickness`: Thickness of the bottom of the pipe.
*  `windsheet_thickness`: Thickness of the windsheet.
*   `mouth_height`: Height of the mouth of the pipe.
*   `pipe_size`: Diameter of the air input at the bottom.
*   `internal_width`: Width of the internal rectangular pipe space.
*   `internal_depth`: Depth of the internal rectangular pipe space.
*   `internal_height`: Height of the main body of the internal rectangular pipe space.
*   `mouth_angle`: Angle of the pipe's mouth.
*   `windsheet_angle`: Angle of the windsheet.
*  `capped`: A boolean variable (Yes/No) to control if the pipe is capped at the top.

I'm also using a cylinder with `fn=30` to create the air input at the bottom of the pipe; this is fine but could be made a variable as well.

I'd prefer the design to be in a modular format, that is, that each of the different components, the pipe, windsheet, mouth, and cap can be defined as their own modules. I don't care how you use the modules as long as it's reasonably readable and understandable.

I was hoping you could use the BOSL2 library, but if you think it'd be better to use another library, I'm open to suggestions. I'm not particularly familiar with BOSL2, so any comments on the generated code would be really useful as well!

Thanks for your help!

Hey, I'm looking for some help creating a parametric, adjustable angle fixing bracket in OpenSCAD. I've been using Rudy Ruffel's design as a starting point, but I'm hoping to get a new version that's more flexible and maybe a bit cleaner.

Here's what I need:

**Core Design:**

*   The bracket is essentially two L-shaped pieces that join together at an adjustable angle.
*   I need to be able to define the width and height of each "leg" of the L. Let's call these `width` and `height` respectively. I would also need the ability to set the thickness of the material used for these pieces, I think `thicknessWall` is what it was called before.
*   The angle between the two L-shapes should be adjustable through a parameter, I guess we can call it `angle`, just like before. This should be able to go from 0 to 90 degrees.
*   There need to be mounting holes for screws in both legs of the bracket. I would need to control the number of screws used along the height of the L and along the length of the L; lets use `numberOfScrewHeight` and `numberOfScrewWidth` for those.
*   The screws should be able to be recessed, just like the original, to be flush or countersunk.
*   I need to be able to specify the diameter of the screw itself (`diametreScrew`), the diameter of the screw head (`diametreHeadScrew`), and the height of the screw head (`heightHeadScrew`).

**Parameter Controls:**

*   **Dimensions:**
    *   `width`:  Width of each leg of the L-shape.
    *   `height`:  Height of each leg of the L-shape.
    *   `thicknessWall`: Thickness of the material for the bracket.
*   **Angle:**
    *   `angle`:  The angle between the two L-shapes (0-90 degrees).
*   **Screws:**
    *   `numberOfScrewHeight`: Number of screws along the height of each L.
    *   `numberOfScrewWidth`: Number of screws along the length of each L.
    *   `diametreScrew`: Diameter of the screw.
    *   `diametreHeadScrew`: Diameter of the screw head.
    *   `heightHeadScrew`: Height of the screw head (for recessing).
*    **Resolution:**
     *   `resolutionScrew`: Resolution for the screw cylinders.
     *    `resolutionHeadScrew`: Resolution for the screw head cylinders.
*   **Other:**
    *   The code should calculate the screw hole center based on width, height, and thickness.
    * If `thicknessWall` is 0, then it should be derived from `width/3` just like in the original.

**Output:**

*   I'd like for the code to output a single .scad file that contains all the parametric features.

Could you generate that for me? Let me know if you need any more clarification.

Hey, I'm looking to get an OpenSCAD design for a softbox that will hold a NeoPixel LED matrix, specifically the kind using WS2812 LEDs. I've got some specific ideas about how I want it to work, and I'd like to make it fully customizable.

Basically, I need the design to have individual segments for each LED in the matrix, kind of like a grid. These segments should be designed to hold a single LED, and they also need to have a little bit of a wall around them for diffusion purposes. I'd also like the ability to include mounting domes for attaching the whole thing to a back panel and optionally some kind of print support. The matrix I'm using is going to be square, but I want to control how many LEDs are in the matrix, the distance between the LEDs, the size of the PCB mount, the overall depth, and of course the width of the walls around each LED.

So, as a design I'd like it to have parameters that allow me to specify:
*   The number of LEDs per row/column (it will be square). Let's call that `Segments`.
*   The distance between LEDs, in millimeters, `LedDistance`.
*   The size of the square PCB mounting area in mm, `PcbSize`.
*   The overall mounting depth in mm, `MountingDepth`.
*   The thickness of the walls surrounding each LED, `WallWidth`.
*   The diameter of a single LED in mm, `LedDiameter`.
*   A boolean-type variable to enable/disable mounting domes: `Mountings`.
*   And another boolean to enable/disable support material, perhaps as a ring: `UsePrintSupport`.

I'm thinking that the design should include two main modules. One module will be for the complete matrix which consists of the individual segments, mount points, and support; the other module will be for testing a single segment by itself.

The primary part of the design will be these individual segments. Each segment will have a circular recess for the LED and a walled-in perimeter to contain and diffuse the light. The segments should be arranged in a grid based on the `Segments` and `LedDistance` parameters. I think the design should also use hulling to create the basic shape of the wall around each LED. I'd like it to have mounting domes in the corners so that I can screw it onto a backplate, so long as the mountings variable is set. I need to create these using a simple cylinder and a negative cube. And finally, the optional support material should consist of some cross beams that create a kind of grid underneath the whole thing.

For the full matrix module, I want the mounting domes and support structure to be optional, controlled by the parameters. The test segment module should generate just one of the segments for rapid prototyping.

I don't have any specific requirements for libraries beyond the standard OpenSCAD features, so I expect this will be a relatively simple set of designs. I'd like the option of generating either the full matrix or a single test segment, based on the selected value of a `Part` variable, which should be either "Matrix" or "Test". I don't need anything complex here - the simplest functional design would work fine.

Hey, I'm looking to design a custom camera stabilizer, like a Glidecam, and I need some help generating the OpenSCAD code. I've got the basic dimensions for the bearings, shafts, and hardware that I'd like to use, and I've got a rough idea for the overall structure. I'd like this design to be parametric, so I can easily change the dimensions later if I need to use different parts.

Here's a breakdown of what I have in mind:

**General Structure:**

The stabilizer will have a central bearing assembly with a main shaft (like a monopod or PVC pipe), handle arms that connect to the central section, and a handle that is perpendicular to the handle arms. The main shaft will be connected to the main bearing, and then there'll be secondary bearings connecting the handle arms to the main bearing.

**Dimensions:**

I'd like these parameters to be customizable:

*   **Main Bearing:**
    *   Inside Diameter
    *   Outside Diameter
    *   Thickness (Z)
*   **Secondary Bearings:**
    *   Inside Diameter
    *   Outside Diameter
    *   Thickness (Z)
*   **Main Shaft:**
    *   Diameter
*   **Handle Shaft:**
    *   Diameter
*   **Bolt:**
    *   Diameter
*   **Washer:**
    *   Diameter
    *   Thickness (Z)
*   **Nut:**
    *   Diameter (flat-to-flat)
    *   Thickness (Z)

I also need to be able to adjust these values for the main assembly:

*   **Main Cylinder Diameter** (this is the diameter of the housing around the main bearing)
*   **Arm Spacing** (the space between the main bearing housing and the handle arms)
*   **Arm Clearance** (this controls how much the arm can rotate before hitting the center housing)

**Modules:**

I would like the OpenSCAD script to include separate modules for:

*   `bearingBushing()`: This should generate the main bearing housing, which needs to account for the main bearing, secondary bearings, washers, and nuts.
*   `bushing()`: This is the inner bushing that the main shaft will pass through.
*   `handleArm()`: This should create the arms that attach to the main bearing housing and the handle.
*   `handle()`: This will create the handle part.
*  `displayAll()`: This should call each of the above modules.
*  `display()`: This should use the `item` variable to either call `displayAll()` or any of the individual modules above.

**Display Mode:**

I'd also like a variable called `item` to control which part of the design is displayed. The options should be "first" for just the `bearingBushing()`, "second" for just the `bushing()`, "third" for just the `handleArm()`, "fourth" for just the `handle()`, and "all" to show everything using `displayAll()`.

**General Features:**

The main bearing housing should be designed so it can hold the main bearing securely, with slots for the retaining washers and holes for the secondary bearings. The handle arms should have a space for the secondary bearings and attach to the central bearing housing with enough clearance for them to rotate freely. The handle should have holes for the bolts that will connect it to the arms.

I hope that's clear enough. Let me know if you need more information!

Okay, I'm looking to create a customizable mount for an action camera, like a GoPro or Xiaomi Yi, to attach to a miniquad drone. I've seen some designs out there, but I need something that's easily adjustable for different frame sizes and camera angles.

Here are the key parameters I'd like to control:

*   **Camera Depth:** The depth of the camera itself.
*   **Back Height:** The height of the vertical support behind the camera.
*   **Front Hole Center-to-Center Distance:** The distance between the centers of the two mounting holes in front.
*   **Rear Hole Center-to-Center Distance:** The distance between the centers of the two mounting holes in the back.
*   **Front-to-Rear Hole Center-to-Center Distance:** The distance between the centers of the front and rear mounting holes.
*   **Camera Angle:** The angle at which the camera tilts up.
*  **Base Thickness:** The thickness of the base of the mount.
*  **Hole Diameter:** The diameter of the mounting holes (should allow for printer tolerances)
*  **Edge Margin:** The amount of material surrounding the mounting holes for strength.
*   **Screw Head Diameter:**  The diameter of the screw heads, for clearance around the holes.
*   **Front Offset:** How far back the angled wedge starts.
*   **Lip On Wedge:** An option to add a small lip to the front of the wedge.
*   **Velcro Strap Width:** The width of the Velcro strap used to secure the camera.
*   **Velcro Strap Thickness:** The thickness of the velcro strap.
* **Added Height:** The amount of height added to the underside of the camera mount for prop clearance.

I'd need the design to account for the screw head clearance around all of the mounting holes, and I'd like a way to include the velcro strap in the design with cutouts to secure it. Also, I need the mounting holes to be counter-bored so the screw heads don't protrude.

I expect the mount to have a base with mounting holes, and a wedge-shaped section angled forward where the camera sits.  The lip, if present, would be at the front of this wedge.

I'd like the OpenSCAD code to be fully parametric, so that I can adjust any of those parameters to create a mount specifically for my needs. Also, I would want the code to be well commented, and I would like the code to use the `linear_extrude`, `difference`, `union`, `translate`, `rotate`, `polygon`, `circle`, `square`, and `cylinder` primitives.

I'm hoping you can generate a complete and functional OpenSCAD file that incorporates all of these parameters.

I'd like to design a ring holder, something that can stack different sized rings, each with its size marked on the side, and a base at the bottom. I have a few specific ideas for how I'd like it to look and function.

First, I need the ability to specify a minimum and maximum ring size, in millimeters. The holder should then create rings, in 1mm increments, between those sizes. For example, if I set the minimum to 16mm and the maximum to 19mm, it would generate rings with diameters of 16mm, 17mm, 18mm, and 19mm.

Each ring should have a cylinder shape, but I also want to have a small change where the bottom of each ring has a slightly larger radius than the top, to help the rings fit onto fingers better. I'd like a parameter to control the amount of this radius difference, something small, maybe 0 to 0.5 mm. The height of each ring should also be adjustable with a parameter.

On the side of each ring I need a mark that indicates the ring's diameter. The mark should be a text label that shows the ring's size. The text should be extruded for easy printing and readability. The label should not interfere with the rings below.

Finally, the whole ring stack needs a base. I'd like to have two options here: a circular base with a user-specified diameter or a square base with a specified side length. I'd need a parameter to choose if it should be a circle or a square.

It'd be great if the whole design is parametric, so all of these parameters are editable and could update the design when changed.

I'm not picky about where the code is written, as long as it works. Please use `$fn=100;` for round objects.

I'd like to create a customizable LED matrix display for a clock, similar to the provided SCAD file "PixelClockMatrix01.scad" but with some changes and a more flexible design approach.

Instead of the fixed grid arrays, I want the display to be generated based on customizable digit definitions. Specifically, I'd like to define each digit (0-9, colon, etc.) as a list of coordinates within a grid, where each coordinate represents the location of an LED. Then, the full display would be a composition of these digits arranged horizontally.

Here's a breakdown of the desired features:

1.  **Digit Definitions:**  I need to be able to define each digit using a list of (x,y) coordinates within a digit grid. For example, the digit "1" might be a vertical line of LEDs at x=1, and "0" might be a rectangle of LEDs. The digit grid doesn't need to be a fixed size - that should be part of the digit definition, so different digits can have different bounding boxes.

2.  **Grid Parameters:**
    *   `ledDistance`: Distance between LEDs (center to center) in mm.
    *   `ledDiameter`: Diameter of the LEDs in mm.
    *   `mountingDepth`: Depth of the LED mounting holes in mm.
    *   `wallWidth`: Width of the supporting walls around the LEDs in mm.
    *   `mountingWidth`: Minimum width of the mounting spacers, if present
    *   `mountingHeight`: Minimum height of the mounting spacers, if present
    *   `digitSpacing`: Spacing in mm between the bounding boxes of digits.

3.  **Display Configuration:**
    *   `displayDigits`: A string representing the digits to display, like "12:34". This would be used to position the digit segments horizontally.
    *   `digitRotation`: optional rotation of all digits around the z-axis in degrees.

4.  **LED Mounting:**
    *   The code should generate a recess for each LED, with a supporting wall around each LED hole. The mounting should work for LEDs pushed in from the top. The bottom edge of the mounting should have a flat bottom.

5.  **Mounting Spacers:**
    *   The code should generate horizontal and vertical mounting spacers. These spacers should be customizable via `mountingWidth` and `mountingHeight`, and their position should be computed such that they form a frame that surrounds all digits and the colon.

6.  **Output:** I'd like the output to be a single STL object suitable for 3D printing.

7. **Dependencies:** The generated SCAD files should not rely on any third party libraries.

I think this setup will be more flexible than the grid-based approach in the provided file.  Could you help me generate the necessary OpenSCAD files?

[User]
I'm looking to get a parametric OpenSCAD design for a camera mount that can handle both a GoPro and a Mobius camera. I'd like it to be adaptable to different quadcopter frames and camera angles.

The design should include a base that attaches to the frame and a wedge that supports the camera at the desired angle. I'd like to be able to print either both parts together, just the base, or just the wedge depending on what I need.

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

*   **Parts\_to\_print**: An option to choose which parts to generate ("Both", "Base", or "Wedge").
*   **angle**: The camera angle in degrees.
*   **velcro\_width**: The width of the velcro strap that will secure the camera
*   **velcro\_thickness**: The thickness of the velcro strap.
*   **camera\_depth**: The depth of the GoPro (or similar) camera housing.
*   **camera\_height**: The height of the GoPro housing.
*   **front\_cc**: Center-to-center distance between the front mounting holes.
*   **rear\_cc**: Center-to-center distance between the rear mounting holes.
*   **front\_rear\_cc**: Distance between the front and rear mounting holes (fore/aft).
*   **hole\_size**: Diameter of the mounting holes.
*  **screw\_head\_size**: Diameter of the screw heads
*   **edge\_thickness**: The amount of material around the mounting holes.
*   **base\_thickness**: The thickness of the base part.
*   **margin**: A small tolerance to adjust for printing inaccuracies - this is important for ensuring the parts fit together properly!

I'd like the design to accommodate a Mobius camera as well, with the following dimensions and features:

*   **mobiusLength**: The length of the Mobius camera.
*   **mobiusWidth**: The width of the Mobius camera.
*   **mobiusRadius**: The radius of the rounded edges on the Mobius camera.
*   **mobiusSupportHeight**: The height of the side supports for the mobius.
*   **velcroSupportThickness**: The thickness of the walls around the velcro strap, should depend on angle of mount (either 3 or 4).

I'm not sure what libraries would be best here, but it seems like a pretty standard solid modeling task. I imagine it would require some linear extrudes and rotations. Let me know what you come up with!

I'd like a parametric OpenSCAD design for a knob, primarily intended for rotary encoders or potentiometers with a 6mm shaft. The knob should have a cylindrical body with a rounded top edge. I need to be able to control the overall diameter and height of the knob, as well as the length of the shaft hole and the radius of the top rounding. The design should include a 6mm hole for the shaft with a flat portion on one side for a D-shaped shaft. It should also include some grooves around the perimeter of the knob for grip. Finally, include a variable for adjusting the tightness of the fit of the shaft hole.

Specifically, I want the following parameters to be adjustable:

*   `Knob_Diameter`: The overall diameter of the knob.
*   `Knob_Height`: The overall height of the knob.
*   `Axis_Lenght`: The length of the shaft hole.
*   `Rounded`: The radius of the top rounding.
*   `Ajustment`: An adjustment value for the shaft hole diameter, allowing for a tighter or looser fit.

The design should:
*   Be a cylindrical body with a rounded top edge.
*   Have a 6mm hole for the shaft, with one flat side to accommodate a D-shaped shaft.
*   Incorporate some form of knurling/grooves around the perimeter for better grip.
*   Use `$fn` for circle resolution control.

Could you generate the OpenSCAD code for this?

Okay, so I'm looking to design a customizable, parametric ghost figure, kind of like a Pac-Man ghost, but with a few tweaks. I've got some ideas about how to make it adjustable for different uses, like for decorations or maybe even small toys.

Here’s what I'm thinking:

**Overall Shape:** The ghost should have a cylindrical body with a dome-shaped head. The bottom of the cylinder should have a wavy skirt. Think of a classic ghost shape, but more geometric and less flowy than a sheet ghost.

**Parameters:** I'd like to be able to control the following through variables at the beginning of the file:

*   `outer_diameter`: This would control the overall width of the body and head.
*   `inner_diameter`: This would define the thickness of the body walls and the head walls as well.
*   `height_body`: Controls the height of the cylindrical body portion.
*   `eye_diameter`: Sets the diameter of the ghost’s eyes.
*  `eye_angle`: Sets the angle for the left and right eyes (relative to the front of the ghost), allowing for a wide-eyed or more focused look.
*   `eye_height`: Controls the vertical position of the eyes on the body.
*   `skirt_size`: This variable would determine the size of the "bumps" on the ghost's skirt.
*   `skirt_number`: This would set the number of bumps, or scallops, that make up the skirt.
*   `head_hole`: A boolean to include or exclude a hole at the top of the head; useful if I want to attach something.
*   `head_hole_diameter`: When `head_hole` is `true`, this specifies the diameter of the hole.

**Specific Details:**

*   The body should be a hollow cylinder.
*   The head should be a hollow sphere, centered above the cylinder body.
*   The eyes should be cylindrical, and positioned on the main body.
*   The skirt should be made of repeating cylinder shapes that connect to the base of the main body.
*   If head\_hole is true, the hole should go all the way through the center of the sphere at the top of the head.

I’d prefer that the code uses standard OpenSCAD primitives and doesn't rely on external libraries. I need a single .scad file that contains all the code. It should be relatively well-commented, so it's clear what each part of the code is doing.

Can you help me generate this code?

		rotate([90,270,i]) cylinder ($fn = 3, r = skirt_size, h = outer_diameter/2+0.1) ;
	} // for

	translate ([0,0,height_body]) sphere(r = inner_diameter/2) ;

		translate([0,0,height_body+(inner_diameter/2)-0.2]) cylinder (r = head_hole_diameter/2, h = outer_diameter-inner_diameter+0.3) ;

I want to create a 3D model of a Pacman ghost, and I'd like it to be parametric so I can easily change its size and features. Here's what I'm looking for:

The basic shape should be a cylinder with a sphere on top, giving the ghost its characteristic rounded top. I'd like to control the overall diameter of the ghost with a parameter, and the height should scale relative to the diameter, specifically 65% of the diameter.

I'd also like the option to add a keychain loop at the top. This should be a small cylindrical loop extending from the top of the sphere, perpendicular to the ghost's main axis. It would be very useful if the addition of the keychain is controlled via an on/off parameter.

Another option I need is a hole for an LED. This should be a cylindrical hole going up the center of the ghost, and the size should be controlled with a parameter, and be selectable for no hole or a hole diameter of 5, 8, or 10 mm.  I imagine that a smaller spherical hole is needed at the top of the cylindrical hole to actually fit an LED, so consider this requirement.

The ghost should have two eye sockets, these are recessed spherical shapes on the front of the ghost. They should be positioned on the front,  horizontally, and be 1/4 diameter up and down from the center of the ghost at the sphere's center, and a distance of diameter/2 out. They should also have a diameter equal to diameter/3.5.

Finally, the bottom edge of the cylinder must have a series of "scallops", to represent the bottom of a ghost. I'm thinking that these are essentially a series of cylinders. The cylinders should be positioned around the base of the cylinder and be a diameter/12.5 above the bottom of the cylinder, and have a length equal to diameter/25*6.5. I'd like 12 of these scallops, evenly spaced.

I'm planning to 3D print this, so using a higher `$fn` like 100 would be great for a smoother model.

Could you please generate the OpenSCAD code for this?

Hey, I'm looking to generate some molecular models and I need a bit of help with the OpenSCAD code. I'd like to be able to create atoms with different elements, and also generate lone pair and valence electrons that I can combine to make molecules.

The atoms should be based on the following elements: Hydrogen, Boron, Carbon, Nitrogen, Oxygen, and a generic Halogen. Each of these should have a central "core" with the element's symbol on it. I'd also like to make a Phosphorus and two Sulfurs (IV and VI) too for more complex molecules, but I can wait if that takes more time.

Each atom type should have specific locations to attach "electrons" (both lone pairs and valence electrons), based on the element. The general idea is that valence electrons from two different atoms should be able to connect to form a bond between the atoms.

I need to generate two types of electrons: "lone pairs" and "valence" electrons. Valence electrons should have a bond-like extension to allow for connecting atoms, with a variable length so I can create different molecular structures. I need a third type of valence electron that is also flexible so that the bonds don't have to be straight, I need it to look like a chain of cylinders and spheres.

The number of lone pairs and valence electrons for each element is:
Hydrogen: 0 lone pairs / 1 valence
Boron: 0 lone pairs / 3 valence
Carbon: 0 lone pairs / 4 valence
Nitrogen: 1 lone pair / 3 valence
Oxygen: 2 lone pairs / 2 valence
Halogens: 3 lone pairs / 1 valence

I need parameters for:
*   The type of object to generate (`type`): "Atom" or "Electron"
*   If type is "Atom":
    *   The element type (`element`): 1 for Hydrogen, 2 for Boron, 3 for Carbon, 4 for Nitrogen, 5 for Oxygen, and 6 for Halogen. 7 for phosphorus, 8 for sulfur IV, and 9 for sulfur VI.
    *   The overall size of the atom (`atom_size`).
*    If type is "Electron":
     *  The type of electron: `electron` (options: "Lone Pair", "Valence", or "Flexible Valence").
     *  The bond length if `electron` is "Valence" or "Flexible Valence" (`bond_length`).

Could you create an OpenSCAD file or files to handle this?  I'm not too worried about the individual shapes, but I'm including what I have in a file if it helps. I'd also like to use the `SirinStencil` font, if that's possible.
