Okay, I'd like to design a customizable electronics enclosure using OpenSCAD. I need it to have rounded corners, mounting screw holes, and a lid that fits snugly. The design should be fully parametric so I can easily adjust dimensions.

Here are the main features and parameters I need:

**Box Dimensions:**

*   **Outer X-Size:** This is the overall width of the box. I need to be able to set this in millimeters.
*   **Outer Y-Size:**  This is the overall depth of the box, settable in mm.
*   **Inner Height:** The usable internal height of the box, in mm.
*   **Bottom/Top Thickness:** The thickness of the box's base and lid, settable in mm.
*   **Corner Radius:**  The radius of the rounded corners of the box, settable in mm.
*   **Screw Hole Diameter:** The diameter for the screw holes, in mm.
*   **Wall Thickness:** The thickness of the box's walls, in mm.

**Lid/Barrier:**

*   **Barrier Thickness:** The thickness of the lip on the box and the recess on the lid that makes the seal when the lid is on, settable in mm. This lip/recess is inset from the outer wall.
*   **Barrier Height:** The height of this lip and recess.
*    **Barrier Tolerance:** Additional width/length to account for printer calibration issues.

**Mounting Noses:**

*   **Number of Screw Noses:** I want to be able to add 0, 2, or 4 mounting noses to the design - either none, one on the top and bottom edges, or two on top and two on the bottom edges.
*   **Screw Nose Diameter:**  The diameter of the hole through the mounting nose, in mm.
*   **Screw Nose Height:** The overall height of the mounting nose, in mm.
*    **Screw Nose Wall Thickness:** The thickness of the material around the screw hole in the mounting nose.

I will also need the design to include a section commented out that allows for adding custom cutouts to the box walls. I would like two example cutouts already present, just like the example given. The example cutouts should be two cylinders lying on their sides on two opposing faces of the box.

I think the design is straightforward enough that we shouldn't need any external libraries. I need the design to generate the box and the lid as two separate, printable objects with corresponding features and screw holes. They should be placed next to each other on the same output. If the X size is larger than the Y size, then the lid should be offset on the Y axis. Otherwise, the lid should be offset along the X axis.

Hey, I'm looking for some help designing a parametric heat pipe bender for 3D printing. I've seen some similar designs, but I need one that's flexible enough for my specific needs.

Basically, I want a tool that can bend heat pipes with a radius that I can specify, but the radius should always be at least 3 times the diameter of the pipe. I want it to be able to bend pipes with a few standard diameters, say 6mm, 8mm, and 10mm, but I'd also like the option to use a custom pipe diameter up to 16mm.

The bender should consist of a few parts: a main handle/base, a lever with a rounded back for bending, an axle that holds the lever, and a bracket that holds the axle. The lever needs cutouts for the pipes at their different diameters. The handle itself needs to be configurable for bends that are over 90 degrees. I'd like to be able to set a parameter to switch between a handle for bending up to 90 degrees, and up to 180 degrees. I guess I'd expect that to just change the position of the handle. The axle should be flat on one side to prevent it from rotating.

I also want to be able to set a tolerance value for the part that grabs the pipe. Something around 0.2mm worked well for a design I saw, but I want to be able to change it if I need to. I was thinking, maybe a slider? Also, the handle and the bracket could be made from separate parts, and I'd like each part to have the option to be rendered separately.

I don't really have a preferred OpenSCAD library. I’m okay with any of them as long as the design can be achieved. It would also be awesome if the generated design had a preview mode that color-coded each part.

Is this something you could help me with?

Hey, I'm looking to create a parametric model for a rotary tool holder, designed to fit a 1-inch flex shaft handle and work with a standard 4-inch C-clamp. I've got a basic idea down in this file called `rotaryfix_v1_final.scad`, but it's not parametric at all. The idea is that it's got a main block that holds the flex shaft, and a base plate that the C-clamp can tighten down on, and I have a separate area for the cut and a separate area for the solid part.

The `rotaryfix_v1_final.scad` file has a few sections. I can describe them briefly: there's a base plate, the main block, an additional cut area, and a final cut area. I'd really like to have a much more flexible design. I can see myself wanting to tweak the shaft diameter, the base plate size, and the various cutout sizes in the main block.

So, could you help me create a parametric OpenSCAD design for this? Specifically, I'd like to be able to control:

*   **Flex Shaft Diameter:** The diameter of the flex shaft handle (currently 1 inch).
*   **Main Block Dimensions:** The overall size and shape of the main block (right now it's a cylinder and a few cubes).
*   **Cutout Dimensions:** Sizes of the various cutouts in the main block (currently cylinders and cubes).
*   **Base Plate Dimensions:** The size and thickness of the base plate, and the positions of the various holes in the base plate.
*   **C-clamp Interface:** The depth and width of the cutouts on the bottom side for the C-Clamp, if that can also be made parametric.

I think it would be helpful to use the `BOSL2` library, if that is not a problem. I can imagine using the various shape generation primitives and maybe some of the more advanced utilities in that library. I would like everything split up into multiple files so that it is easy to read.

The output of the final model should be something that looks like the design in `rotaryfix_v1_final.scad` as a starting point, but that we can modify easily.

Okay, I'm looking to create something similar to the "RECURSION 3D" project I saw on Thingiverse, but I'd like to control more of the parameters directly and expand on its functionality. Basically, I want to generate these kind of futuristic building or city-like structures using a recursive algorithm, but with a lot more flexibility in terms of the base shape, the recursive steps, and even the random element. I'd prefer all new code instead of trying to modify the existing thing.

Here's what I'm thinking for the base: I'd like to be able to choose between a polygonal base, a rectangular base, or a circular base, just like the original. For the polygonal base, I'd need to be able to specify the number of sides, the length of each side, whether the generated structure is inscribed or circumscribed within the polygon, and a separation distance. I also want an option for supports for the polygonal base if the figure is larger, and I need control of the support thickness and separation. For rectangle bases, I need to specify the X and Y dimensions and for circular base the diameter. I also want the base height to be a customizable parameter.

Now, for the recursive part. I'd like to control how each level is created, which could be either cubes or cylinders. I'd like to introduce a selection of different options of how each cube or cylinder can be recursively subdivided or modified:

1.  **Reduction:** A simpler option, just reducing the size of the shape at the next level.
2.  **Division:** Split the shape in two along either X or Y (or radius) axis.
3.  **Pyramid:** Convert a cube to a pyramid structure with smaller pyramid pieces at each corner, like in the original, but with more control over how the pyramid is generated. Maybe I could also add a central pyramid, and also control the number and shape of lateral structures.
4.  **Column/Disks:** For cylinders, the recursive step could add columns or disk like structures.
5.  **Arch/Dome:**  For cylinders, add an architectural element of arcs and domes, maybe using spheres.
6.  **Random:** Randomly pick any of the previous 5 options for each recursive step.

I'd like to control the minimum size at which recursion stops. Also, the level height will need to be a parameter. It also seems essential to maintain the random number generation approach with a seed, but I'd like to be able to specify the number of random numbers to generate. Finally, the seed needs to be engraved or shown on the bottom of the figure. I'd like that to be mirrored and I'd like to control the size of the text in this element. I don't think I need specific control over the $fn variable, but I'd like to maintain control over the general smoothness of the cylinders.

I'm thinking this will require at least a couple of files. One file should contain the main module with all the customizable parameters and recursive logic, and the other should be a library or functions that can help define the different kinds of structures (pyramids, arches, domes, columns, etc). This library could be expanded later as a future feature. I'm not using any custom libraries, so you don't need to worry about that.

 Hints for print:
 NO SUPPORTS!! : geometry generated print well without supports.
 INFILL recomended:15-20 Acts as support from inside and the top/flat parts prints better.

[User]
I'm looking to create some 3D models of stones, and I'd like them to be parametric so I can easily adjust their shape and size. I want to have two main types: a "boulder" style, which should be relatively smooth and rounded, and a "cutstone" style, which should have a more blocky, angular appearance with flat faces.

Specifically, I'd like the design to work like this:

1.  **Base Shape:** Both the boulder and cutstone should be derived from a basic unit shape which is a 1x1x1 cube (or at least roughly that size), and then manipulated to achieve the desired shapes. I want to scale them so they are approximately 1x1x0.5 in size, though that should be a parameter too.

2.  **Boulder Generation:** The boulder should be generated using a random or semi-random process to give it an irregular, organic appearance. It would be great if the smoothness could be adjustable. I need a `boulder(seed)` module.

3.  **Cutstone Generation:** The cutstone should be generated with a random or semi-random process to give a rough, cut stone appearance, while still retaining a blocky look. Similar to the boulder, I want a way to adjust how rough or smooth it is. I need a `cutstone(seed)` module.

4.  **Seed Parameter:** Both the boulder and cutstone modules should accept a `seed` parameter, which allows for the generation of different shapes, while maintaining the overall style and characteristics. This way I can generate multiple variations by changing the seed.

5.  **Preview:** I'd like to be able to generate both the boulder and cutstone side-by-side as separate objects using `translate`. Also, I would like to preview what happens when a boulder and a cutstone of different sizes intersect.

6.  **Parameters:** I'd like parameters for: the seed value (an integer) and a scaling factor `s` for use in the intersection. For the stones I would like a scaling factor also.

Could you generate the OpenSCAD code for this? I'm not using any external libraries so everything needs to be in a single .scad file. Thanks!

I'm looking to design a customizable tag that can clip onto things, similar to the design at http://www.thingiverse.com/thing:1693879, but I want it to be fully parametric and a bit more flexible. I want to be able to specify the dimensions of the tag itself, the dimensions of the clip, and what text (if any) appears on the tag.

Specifically, I'd like:

*   **Tag Dimensions:** The ability to set the width, height, and thickness of the rectangular tag.
*   **Clip Dimensions:** Control over the clip's overall height, its width (which defines the clip's opening size), and the radius of the circular sections making up the clip shape. I'd also like to control the offset (distance) of the clip from the tag face and its thickness/depth.
*   **Text Customization:**
    *   An option to leave the tag blank.
    *   If text is desired, the ability to enter a string of characters (not just numbers).
    *   Control over the text's font, size, and horizontal/vertical alignment on the tag.
*   **Rounded Edges:** An option to add a radius to the edges and corners of the tag itself.
*   **Materials/tolerances**: The ability to define the "clearance" needed for the clip so that it has a snug but not overly tight fit. Also the ability to define a slight bevel on the tag's edge.

I would want the output to be a parametric OpenSCAD file or set of files that I can easily customize. I'm not using any specific libraries yet but would be open to using them if it makes things easier. Something like the BOSL2 library might be nice for the rounded corners and for text/alignment controls if those things make sense. I don't want to get bogged down in complex code, so I'm happy for you to include the more complex operations in library modules or your code.

Okay, so I'm looking to create a customizable, printable space invaders fleet generator in OpenSCAD. I want to be able to specify the number of rows and columns of invaders, as well as the pixel size of the invaders themselves. Each invader should be made up of individual cubes, with the option to randomize the pattern of the cubes. Also, I would like to be able to generate a matching base or support for the invaders, either one single base for the entire fleet or an individual base for each invader. Finally, I need the option to output the invaders, the base, or both together.

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

*   **Seed:** A numeric seed to control the randomness of the invader patterns.
*   **Part:** A selection for the output: "invader" (only invaders), "base" (only base), or "both" (invaders and base).
*   **Fleet Rows:**  The number of rows in the fleet.
*   **Fleet Columns:** The number of columns in the fleet.
*   **Invader Width:** The width of the invader in "pixels" (number of cubes).
*   **Invader Height:** The height of the invader in "pixels".
*   **Separated Bases:** A yes/no option to create either one large base under the entire fleet, or a separate base for each invader.

The invaders should consist of a symmetrical pattern of cubes, and the base should be a solid rectangle with a cutout for the invader pattern. I think using a `color()` module for the invaders and the bases would be nice. Also, I would like to specify different colors. I think the invaders should be gold and the bases aqua. I believe this would involve a nested loop to generate the invaders within the `invader()` module and then using those for both generating the fleet and the cut out in the base. Also, the base should be slightly larger than the grid of invaders to ensure the invaders fit nicely. A parameter p should be included that defines the density of the cubes and should be set as a default of 0.6. The grid should be set as a default of 5.

Could you generate the necessary OpenSCAD code for this? I'm assuming it'll need to be split across a couple of modules. This looks like a fun little project. Thank you!

Hey, I'm looking to design a Star Trek-style deck label, like the ones seen on the Enterprise-D. It's basically a rounded-rectangle backplate with text extruded on top of it. I've been playing around with some designs, but I'm hoping you can generate something parametric so I can adjust it more easily.

Here's what I'm thinking:

*   **Backplate:**
    *   It should be a rounded rectangle shape with a specified `base_thickness`, `base_width`, and `base_height`. The ends should be half-cylinders or circles, so it's a pill shape.
    *   The backplate should have a base color, which I'll probably set to red.
    *   I need to be able to select if I want just the backplate, just the text, or both printed together.

*   **Text:**
    *   The text will be extruded on top of the backplate, so it should sit on the top face.
    *   The text should include the deck number, the section number, and a title. There should also be an option for two lines of description text below the title.
    *   The deck and section numbers should be separated by a vertical line and a small gap.
    *   The size of the text should be based on the `base_height`, but I'll also need a parameter to set the extrusion `text_height`.
    *   The font should be selectable from a list of supported fonts. I know that "Russo One" looks pretty close to the text used on the show, so I'd like to be able to use that if possible. The font color should be white, but it would be nice to be able to change it for the text independently of the backplate.
    *   I need control over the spacing of the text, so I'm hoping it could calculate all the text offsets parametrically.

I need the generated file(s) to be parametric. I'd like to set `part` to either "back", "text", or "both" to control what gets rendered, along with other parameters controlling the size, fonts, colors, etc.

Could you also generate a file that generates a "template" file, which uses these components, so I can more easily adjust those global parameters?

I'm hoping you can use the standard OpenSCAD library for this.

I'd like to create a customizable hex bit holder using OpenSCAD, similar to the one described in the provided text. It should be fully parametric, allowing me to control the number of rows and columns, the footer height, the wall height above the footer, and the spacing between the holes, both in rows and columns.

Specifically, I need to be able to:
*   Set the number of rows and columns of bit holes.
*   Adjust the height of the footer.
*   Adjust the height of the wall above the footer.
*   Control the spacing between holes in both rows and columns separately.
*   Adjust the edge spacing for rows and columns. This spacing can be negative to "open" the holes on the edges if needed.
*   Set the diameter of the bit holes.
*   Choose between hexagonal and round holes.
*   Set the radius of the corner fillets.

I'm also looking for the ability to easily scale the entire design in the X and Y dimensions, in case I need to compensate for tolerances on my printer.

I understand that the design uses a fillet library by jfhbrook which should be directly included. I need the design to be fully self-contained in a single file (or very few files). Could you generate the necessary OpenSCAD code for me? Thanks!

I need a small, customizable plug, sort of like a stepped cylinder. I've got a hole in my lawnmower I need to fill, and this looks like it might be perfect.

Basically, it needs three cylindrical sections stacked on top of each other.

The bottom section should be a short cylinder with a slightly tapered wall, so it's like a truncated cone. I'll need to be able to control the radius at the base (the bottom of the plug), the taper, and the height of this bottom piece.

Then there's the middle section, which is a simple cylinder acting as the shaft. I need to control its radius and height too.

Finally, the top section is another short cylinder with a taper, like the bottom section. Again, I need to be able to set the radius at the top, the taper, and the height of this section.

I think it would be best if the tapered sections were created using `cylinder(r1=..., r2=..., h=...)` rather than linear extrusions of circles.

I'd like this done in OpenSCAD, and I'd like all of the dimensions to be parameters at the top of the file so I can easily change them to fit my needs. I don't need it to be especially robust, just something simple that I can easily tweak and print. I'm not using any external libraries for this kind of simple design.

Could you whip that up for me?

Hi! I'm looking to get a customizable filament clip designed in OpenSCAD. I've seen a few designs out there, but I want one that's flexible and easy to use, and has the option for a handle.

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

*   **filament\_diameter:** This should be a dropdown with options for 3.0, 2.85, and 1.75 mm to accommodate different filament sizes.
*   **handle:** A simple boolean (1 for on, 0 for off) to enable or disable a handle on the clip.
*   **handle\_diameter:** If the handle is enabled, this should allow me to change the diameter of the handle, with a reasonable range, say 3mm to 30mm.
*   **thickness:** The width of the band of the clip.
*   **object\_height:** The height of the clip, essentially its extrusion height.
*   **expansion:** An adjustment to the inner diameter of the clip, useful for fine-tuning the fit (positive value to loosen, negative to tighten)
*   **rotation\_2nd\_ring:** The rotation of a second ring added to the clip for better grip. This should allow for an asymmetrical design if desired, with a range from 100 to 200 degrees.

The design itself should consist of a circular clip with an opening, and a second, offset ring for better grip. The handle should be a circle or donut-like shape extending from the outside of the clip.

I think this could be done with simple circle and square functions, combined with rotations and translations. I don't think I need any fancy libraries for this.

Could you generate the OpenSCAD code for this, please?

Okay, I need an OpenSCAD generator for film reels, specifically for Super 8, standard 8mm, and 16mm film. I'd like it to be fully parametric so I can adjust all the dimensions.

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

*   **Film Width:**  I need to be able to specify either 8mm or 16mm.
*   **Center Hole:**
    *   Inner Diameter:  This will vary depending on the film type, something like 8mm for standard 8, and 13mm for Super 8.
    *   Insert Length, Number, and Width:  These are the little tabs that engage with the film spool, and they will also vary based on film type. For Super 8 I need to set the length, number, and width individually. For a normal 8, I need a different length, number, and width.
    *   Square Hole Option: For 16mm, I need the ability to switch to a square center hole instead of the standard circle with tabs, and I need to be able to control the size of this square.
*   **Reel Size:**
    *   Outer Diameter:  I want to be able to choose from standard sizes (like 3, 4, 5, 6, and 7 inch) but ideally I'd like to specify it directly in mm.
    *   Core Diameter: The diameter of the inner hub around which the film rolls. Again, I'd like to set this in mm.
*   **Spoke Design:**
    *   Spokes or Solid: The option for either a solid reel or one with spokes.
    *   Number of Spokes: If spokes are selected, I need to specify how many.
    *   Ring and Spoke Widths:  I'd need to adjust the widths of the outer ring, the inner ring around the core, and the spokes themselves.
*   **Fitting:**
    *   Fitting Width: How wide is the engagement between the two halves of the reel.
    *   Core Tightness: The ability to adjust how tight the center hole fits on the film spool, and include the option for negative numbers.
    *   Fitting Spacer:  The extra space in the fitting between the two halves of the reel so it's not a perfectly snug fit, or not too tight.
*   **Other:**
    *   Height: The overall height/thickness of the reel halves.
    *    Film Insert Width: The width of the small inserts inside the core which hold the film onto the spool.

The reel should be composed of two parts: a bottom and a top half, designed to fit together nicely, but in only one orientation. This should be done with a male-female fitting system with an additional alignment guide so they will only fit together one way. I will need to specify the type of part that is printed: top or bottom half.

I'd like this to be designed as a single parametric OpenSCAD file, where I can select what part I would like to output. I don't have any code to provide, and I don't want to use any special libraries.

Hey, I'm looking for an OpenSCAD design for a phone holder/mask specifically for AR games like Pokemon Go. The idea is to have something that helps me keep the phone stable for better straight-line aiming, kinda like a sight on a weapon.

Here's the basic concept:

*   It needs to be parametric, so I can adjust it to different phone sizes. I'll need parameters for the phone's width and height (measured from the bottom), and also for the height of the side holding walls that will grip the phone.

*   I'd like there to be a "finger channel" or guide in the middle, so my finger can act like a sight for aiming. This also needs to be parametric in both width, and depth from the front of the device, in order to accommodate different sized fingers.

*   There should be a wall width parameter, and a small margin between the phone and the side walls.

*   I also need a parameter to control the overall depth of the holder.

*   A binary parameter for whether the finger hole can be used as a hole or a bump.

*   Lastly, a parameter to toggle the creation of a support beam or wall that is behind the entire device to ensure structural stability.

I'm not too familiar with more complex OpenSCAD things, so I'd prefer something simple. No need to get fancy. I do expect it to be fully functional though - I should be able to configure all of those parameters and get a usable STL file. I also am not sure what libraries are out there, so please use whatever you want - but I'd appreciate it if you'd tell me what you end up using.
