I need a design for a Raspberry Pi mount, kind of like the one I have, but more flexible and easier to customize. I'd like to be able to mount a Raspberry Pi securely, plus have a spot for a small RF transmitter, something like the commonly available 19.2mm x 19.2mm units. The key is that I want a parametric design so I can tweak dimensions easily.

Specifically, I need the following:

*   **Base Plate:** This will be the main mounting surface and should have mounting holes for the Pi.
*   **Pi Mounting Posts:** I want posts that raise the Pi up from the base plate. The posts should have small pegs or something to fit into the Pi's mounting holes.
*   **RF Transmitter Mount:** There should be a space for a 19.2mm x 19.2mm RF transmitter to snugly fit into the base, with a method to secure it, like some side clips.
*   **Optional Cable Clips:** I'd like some places to route small wires or cables, ideally simple circular clips that can be parametrically adjusted.
*   **Stand-Alone Capability:** The mount should be able to stand on its own, so it should have feet or a wide enough base.

I'm looking for an OpenSCAD design that lets me easily adjust:

*   **Overall dimensions:** Width and height of the base plate.
*   **Pi mounting hole locations:**  X and Y distances of the mounting holes, as well as the hole diameter.
*   **Post height and diameter**.
*  **RF transmitter location and size.**
*   **Clip diameter, width, depth and location.**
*   **Base plate thickness and foot height.**
*   **Corner Radius:** Be able to round the corners of the base plate.
*   **Base Stand Offs** Let me modify the shape of the foot/stand on the bottom.

For the design, I think it would be useful if you used the `hull()` function to create a smooth transition between different parts of the base, and maybe `minkowski()` for some of the rounded corner features. The `linear_extrude()` function will be great for the base and for adding thickness to 2D shapes. I would also like for you to use `difference()` and `union()` to generate the correct parts. Please use `translate()` and `rotate()` to position the pieces correctly.

I'm not really using any external libraries right now, so please generate the entire design from scratch. I would like the final product to be parametric, well documented, and easy to use.

Hey, I'm looking to generate a 2D maze using OpenSCAD, similar to the one I found on Thingiverse, but I need it to be fully parametric and I'd like to be able to specify a few extra features.

Basically, I want a rectangular maze with configurable rows and columns. Each cell of the maze will have a consistent width and height (which I'll specify as a parameter). Walls should separate the cells, also with their own thickness parameter. I also need to be able to control the overall height and thickness of the maze base. And finally, I'd like to be able to generate it both with and without a back. So ideally a boolean parameter to toggle this.

The maze should be generated randomly, with a single path from the top left cell to the bottom right cell, like a typical maze. The walls should be generated using the same algorithm as the one in the provided .scad file.

I'd like all the parameters to be easily adjustable at the top of the file, things like the number of rows, number of columns, cell width, cell wall thickness, overall maze height, the height of the base (bottom), and a boolean to turn on or off the back plate.

I want to be able to export this in STL format for 3D printing, so I need it to generate solid geometry.

Can you help me design this in OpenSCAD? I don't need any fancy libraries, just the core language features. I am hoping for single .scad file, and no external libraries.

Okay, I'd like to request a parametric box generator in OpenSCAD, but it needs to include a way to create panels with cutouts and text. I've seen a project that does something similar, and I think it would be really useful for my projects.

Here are the core features I need:

*   **Parametric Box Dimensions:**  The box should have parameters for length, width, and height, as well as wall thickness.
*   **Rounded Corners:**  I need the ability to control the corner radius of the box, as well as the resolution/smoothness of those rounded corners.
*   **Panel/Rail Tolerance:** There should be a parameter to adjust the tolerance for panels/rails, creating a small gap.
*   **PCB Feet:** It should have optional PCB feet support, and those should also be parametric. I need to control the PCB's position and size, as well as the foot height, diameter, and mounting hole diameter.
*   **Ventilation Holes:** The box should have optional ventilation holes along the sides. I should be able to control the width of those holes and whether or not they are decorated to extend through the shell.
*   **Export Options:** I need to be able to select which parts of the box to generate (top shell, bottom shell, front panel, back panel) so I can export them individually.
*   **Panel Maker:** Crucially, it needs to include a panel maker so I can create custom cutouts and labels. This needs to support:
    *   Square and circular cutouts/holes, and also allow for fillets for square cutouts.
    *   Linear text labels
    *   Circular text labels

I also need to be able to specify colors for the shell and the panels separately.

I don't need any specific libraries; it all needs to be built from scratch. I'm going to use the dimensions from the images as a reference; they are not fixed values but provide a general idea of how the box should appear. The goal is a fully parametric box generator with the included panel designer.

Here are some of the dimensions that should be parameters, and their default values:

*   Length: 160
*   Width: 170
*   Height: 100
*   Thickness: 2
*   Fillet radius: 2
*   Fillet resolution: 50
*   Panel gap tolerance: 0.9
*   PCB feet enable: Yes
*   Ventilation holes: Yes
*   Ventilation width: 1.5
*   PCB corner X position: 7
*   PCB corner Y position: 6
*   PCB Length: 70
*   PCB Width: 50
*   Foot height: 10
*   Foot diameter: 8
*   Foot hole diameter: 3
*   Top shell: No
*   Bottom shell: Yes
*   Front panel: Yes
*   Back panel: Yes

And for colors, I'd like:
* shell color: "Orange"
* panel color: "OrangeRed"

For the Panel Maker, I would expect to see the following modules:

*   `Panel(Length,Width,Thick,Filet)`
*  `CylinderHole(OnOff,Cx,Cy,Cdia)`
*   `SquareHole(OnOff,Sx,Sy,Sl,Sw,Filet)`
*   `LText(OnOff,Tx,Ty,Font,Size,Content)`
*   `CText(OnOff,Tx,Ty,Font,Size,TxtRadius,Angl,Turn,Content)`

The placement of these features is not rigid; for instance, the user could place labels within the base shell by applying a translation to the text itself, or define some text in the front/back panel but the panel itself can be also used as a simple panel to cut holes in. The code should also be well-commented so it's clear how it works.

[User]
I'd like to create a customizable container with text wrapped around its cylindrical wall. The text should be raised and form part of the wall itself, not just be etched on the surface. I'd like the ability to adjust the text, the radius of the cylinder, the total height, the thickness of the wall, the height of the base, and how far out the base extends beyond the text. Also it should allow me to adjust the spacing between the characters on the wall.

Specifically, I want a parametric OpenSCAD design that fulfills these requirements. I want to control the following parameters:
*   `text`: The text that will wrap around the container.
*   `radius`: The inner radius of the cylindrical wall.
*   `height`: The total height of the container (including the base and text).
*   `wall_thickness`: The thickness of the cylindrical wall.
*   `bottom_height`: The height of the base of the container.
*   `bottom_factor`: A factor that controls the width of the bottom base. This can be a factor relative to the character height. A larger value would make the bottom wider.
*   `font_density`: Controls the spacing between the characters. Higher values mean more space between the characters.
I'm envisioning something like the example code provided. The design should be such that the text is smoothly integrated into the wall and is not a separate element added on top. I'd prefer a fast-rendering design even if it means slightly less visual smoothness.

Please generate all required .scad files. No need for external libraries at this time.

Hi, I'm looking to create a motor adapter in OpenSCAD, similar to the one I have a design for but I'd like it to be fully parametric. The goal is to adapt a smaller, cheaper 28BYJ-48 stepper motor to the mounting pattern of a larger 17HS NEMA 17 stepper motor. I've been using PLA at 220 degrees, if that's useful info.

My current design uses hardcoded values, and I'd really appreciate it if you could make this a fully parametric design. Specifically, I need to be able to specify:

*   The height of the 17HS motor (e.g., 34mm).
*   The width/length of the 17HS motor (e.g., 42.3mm, assuming it's square).
*   The distance from the mounting holes on the 17HS motor to its outer edge (e.g., 5.65mm).
*   The overall diameter of the 28BYJ-48 motor (e.g., 28.5mm).
*   The height of the mounting bosses for the 28BYJ-48.
*   The overall size/depth of the side box for the 28BYJ-48
* The radius of the bolts to mount the 28BYJ-48

The adapter should consist of:

1.  A base that is a rectangular box matching the dimensions of the 17HS motor, with a centrally located hole for the shaft of the 28BYJ-48 motor.
2.  Four mounting holes for the 17HS motor that are offset from the edge per that `kd` value.
3.  A circular recess on one side for mounting the 28BYJ-48 motor, ensuring it's concentric with the motor shaft hole.
4.  A rectangular mounting piece to accommodate the 28BYJ-48.
5. The side box for the 28BYJ-48.
6. Two bolt holes for mounting the 28BYJ-48

I'd like to use OpenSCAD libraries for this, if possible, to ensure that I can easily adjust dimensions and other parameters later without having to edit too much geometry. I am not sure which specific library would be best, so I'd welcome your suggestions. I can also make sure the appropriate libraries are installed.

It would be amazing if the generated code is well-commented, too. Also, could you use `$fn` to control the quality of the curved elements, and make it a variable that the user can control?

Could you do that for me, please?

I need an OpenSCAD design for an antenna holder for a drone, specifically the Armattan F1-5. I've got a design in mind that I want to be parametric so I can easily tweak it later.

Here are the key features I need:

1.  **Base:** A rectangular base with rounded corners. I'd like to control the base's length, width, and thickness, as well as the corner radius.
2.  **Antenna Tubes:** Two tubes that hold the antenna wires. They should be angled, one at 45 degrees and the other at -45 degrees relative to the base's plane. I need to set their length, outer diameter, and inner diameter. I also need control over their position relative to the base and to each other.
3.  **Mounting Hole:** A central hole in the base for mounting to the drone frame. I'd need to define the hole's diameter.
4. **Hole support:**  I would like a support under the antenna tubes for more stability. This should probably be made of two rectangular cutouts under the tubes. The length, width, and height should be configurable.

I'd like to be able to tweak all these dimensions. So the design should be parametric, using variables for all of these features. Please generate the necessary .scad file. I don't need any external libraries for this design.

I need a custom salt funnel designed for 3D printing, and I'd like it to be parametric so I can easily adjust it to fit my needs. I'm thinking something that would attach to a salt intake slot.

Here's what I have in mind:

**Basic Shape:** The funnel should have a cylindrical upper portion that narrows into a frustum (truncated cone), ending in a straight cylindrical section to fit into the salt intake. This is the main body of the funnel.

**Key Dimensions:** I'd like to be able to control these dimensions:

*   `SALT_INTAKE_INNER_RADIUS`: The inner radius of the final cylindrical section, which will fit *into* the salt intake slot. This should be the outer diameter of the straight cylinder.
*   `SALT_INTAKE_OUTER_RADIUS`: The inner radius of the circle where the supporting pillars connect to the ground (or mounting surface).
*   `OUTER_RADIUS`: The overall diameter of the top of the funnel.
*   `WALL_THICKNESS`: The thickness of the funnel walls.
*   `FUNNEL_HEIGHT`: The height of the frustum/cone portion of the funnel.
*   `STRAIGHT_PART_HEIGHT`: The height of the straight cylindrical section at the bottom.

**Pillars:** The funnel needs supporting pillars that extend downwards. I need parameters for:

*   `NUMBER_OF_PILLARS`: How many pillars the funnel has.
*   `WIDTH_OF_PILLARS`: The width of each pillar (x-dimension)
*   `LENGTH_OF_PILLARS`: The length of each pillar (y-dimension).
*    `HEIGHT_OF_PILLARS`: The vertical distance from the bottom of the salt outlet to the bottom of the pillars.

I think that covers it. It would be amazing if you could generate an OpenSCAD file that does all of this. Oh, and I'd like $fn to be controllable so I can adjust resolution of the circle objects! I guess that's what `fn` does.

I need a parametric design for a mounting bracket, and I'd like to be able to adjust all the key dimensions easily.

The base of the bracket should be a rectangular plate, and I need to be able to set its length, width, and thickness. There will also be a beam coming up from the base, which will be centered on the base, but displaced in the X and Y directions. I need to set the beam's width, length (which is along the length of the base), and height as well. Finally, I'd like to set the displacement of the beam from the center in the x and y directions. I want to be able to control the $fn for higher resolution as well.

Basically, I'd like to reproduce the shape in the example, but with all of those parameters exposed, so I don't need to edit the code each time I want a different shape.

Can you provide me with the OpenSCAD code? I'm not looking for any fancy libraries here.

Hey, I'm looking to design a flexible bracelet using OpenSCAD. I have a basic idea in mind, but I need some help making it parametric.

Essentially, the bracelet will be made up of repeating segments, sort of like links in a chain. Each segment will have a central, flat, extruded part with a sort of diamond-shaped profile, and then additional geometrical bits at each end that allow the segments to flex and connect with each other. The key thing is, I'd like to easily control the overall size of the bracelet, the width of the segments, and the number of segments.

Specifically, I'm picturing the central part of each segment as a linear extrusion of a polygon. The polygon should have six points that creates a sort of stretched-out diamond shape with two points on the center line and the others forming the angled parts of the diamond. I'd like the thickness of this extrusion to be relatively thin, as well as the thickness of the other connecting geometry on the ends. I think having the polygon extrude both up and down from its central plane would be good.

Then, on each end of the polygon extrusion, I'd like a small, connecting geometrical shape that allows the segments to join and flex. This connector bit should involve a polyhedron defined by 8 points and twelve faces, which forms something that kind of has the shape of two pyramids on top of each other with the connecting polygon extrusion running through the middle. It's crucial that this part is defined in such a way that segments can link and articulate. The overall look should be fairly smooth, no sharp corners.

I'm hoping to make this completely parametric, so I can change the bracelet radius, the segment width, and the number of segments. Could you help me create the OpenSCAD files for this? I don't need any extra library files other than the standard OpenSCAD libraries and functions.

Hey, I'm looking to get some custom pegboard accessories designed in OpenSCAD. I really like the "Manhattan Pegboard Collection" and want to start with something similar to their triangle shelf, but with a few modifications and more control.

Here's what I'm thinking: I need a triangle shelf, the basic shape is there in their example. It's a right triangle with the right angle running along the y-axis. I want to be able to control the width and depth (the legs of the right triangle) separately. I'd also like control over the height of the shelf. The shelf should sit flat on a pegboard using pegs along the back two sides - just like the example, but I want to specify the number of pegs, not just a span. I'd also like some control over the peg dimensions.

To be clear:
*   **Shelf Shape:** Right triangle prism.
*   **Parameters:**
    *   `shelf_width`: Length of the triangle's leg along the x-axis.
    *   `shelf_depth`: Length of the triangle's leg along the y-axis.
    *   `shelf_height`: Height of the prism.
    *   `num_pegs_x`: Number of pegs on the side that runs along the x-axis
    *   `num_pegs_y`: Number of pegs on the side that runs along the y-axis.
    *   `peg_diameter`: Diameter of the pegs.
    *   `peg_length`: Length of the pegs.
    *   `peg_spacing`: Distance between peg centers.
*  The pegs should be positioned centered on the *edges* of the right-triangle back faces. So the first peg should be halfway between the corners, and be equally spaced along the edges.
*  I also need the ability to center the shelf on the Z axis, just in case the pegboard is thicker than usual or something. Maybe a boolean, like `center_z`?

Could you generate the necessary OpenSCAD file(s) for this design? I assume I'll be using the basic OpenSCAD built-in modules so you don't need to specify those.

Hey there! I'm looking to create some customizable pegboard bins, and I've seen some designs that are close, but I need a bit more flexibility.

I'm thinking of a basic rectangular bin shape, but with the option to easily adjust its internal dimensions. Specifically, I need to control the width, depth, and height of the *inside* of the bin. I also need to set the wall thickness. For the mounting, I want to have pegs on the back to attach to a standard pegboard.

The most important thing is the peg placement. I need to be able to set the number of pegs and have them evenly spaced horizontally. Specifically, I'd like to be able to set a parameter to have either one peg centered, two pegs, three pegs, or four pegs. So, a `pegs` parameter of 0 means one centered peg, 1 means two pegs, 2 means three pegs, etc. I know standard pegboard peg spacing is 25.4mm center to center. The peg diameter is 6.35mm, and they need to stick out at least 12mm.

I would like this to be one scad file, but if it makes more sense to split it into modules, I'm okay with that. Also, I need to be able to adjust all measurements in millimeters.

Could you create an OpenSCAD file for that? I'm not very familiar with all the math behind spacing multiple pegs, so I could really use the help. I'm also not using any fancy libraries. Just plain OpenSCAD, please!

I'm looking for an OpenSCAD design for a customizable pegboard bin. I'd like it to be parametric, so I can easily adjust the size.

Specifically, I need to be able to control the internal width, depth, and height of the bin, as well as the thickness of the walls. It should also have pegs on the back for mounting to a standard pegboard. The number of peg *pairs* should be adjustable too - from one pair centered to two pairs, or more if I want it later.

The pegs should be spaced 25.4mm apart (1 inch) and have a diameter of 6.35mm (1/4 inch), and extend about 12mm from the back. The design should use the standard "difference" technique to create the bin shape. I would like to include a base for the bin but also have the option of removing it (so I can use the bin for tools or whatever).

I don't have any OpenSCAD code that I can provide right now but I want to start from scratch, and am not using any libraries yet.

I'm looking to create a series of customizable pegboard accessories, and I'd like to start with a rounded bin-like holder. I need it to be parametric so I can easily adjust the dimensions.

Specifically, I need the bin to have a cylindrical interior, and a flat back that connects to the pegboard. The back should be a rectangular prism. The front of the bin should be a cylinder, but with a slightly larger diameter to create the walls of the bin. I want the bottom of the cylinder to be optional; that is, I want to be able to set the wall thickness to zero which would remove the base.

The most important thing is the peg attachment system. The pegs need to be arranged in two rows on the back of the rectangular prism, with the horizontal spacing between them controlled by a "pegs" parameter. 0 would center a single peg, 1 would be two pegs symmetrically spaced around the midpoint, 2 would be 3 pegs, etc. The vertical spacing between the two rows of pegs is fixed at the standard 1 inch (25.4mm) pegboard spacing. The peg diameter needs to be 6.35mm and the length of the pegs should also be adjustable with a parameter.

The key parameters I'd like to control are:

*   `width`: The interior diameter of the cylindrical bin
*   `depth`: The depth of the bin (how far it sticks out from the pegboard)
*   `height`: The height of the bin
*   `thickness`: The wall thickness of the bin; setting this to 0 should remove the bottom of the bin.
*   `pegs`:  The number of peg pairs to include
*   `pegLength`: The length of the peg extensions
*   `pegCenterToCenterDistance`: The fixed 25.4mm pegboard spacing (but keep this as a parameter in case I need to adjust it)
*  `pegDiameter`: The 6.35mm peg diameter (also as a parameter in case I need to adjust it)

I'd like the code to be well-organized and use comments to explain each part. I'm not sure if libraries are necessary for this, but it might be useful if you have some recommendations. I'm thinking this would all be in one scad file, if that's feasible.
