I'd like to create a customizable neckerchief slide, you know, like a woggle. It should be a roughly spherical shape with a hole going through the middle for the neckerchief, and then three more holes around the sides. I want to be able to put some text, like initials, between those side holes.

I need an OpenSCAD file that can do this, and I'd like it to be parametric, so I can easily change things later.

Here are the key things I'd like to be able to control:

*   **The text**: I'd want to be able to change the three letters or numbers that show up on the slide. It should probably default to "BSA".  And should allow for blank text, so no glyphs appear on the slide.
*   **Text position**: I'd like the option to either have the text cut *into* the surface of the slide (recessed) or have it stick *out* from the surface (extruded).
*   **Smoothness**: The round part of the slide doesn't have to be super smooth. A lower setting would give it a blockier look, like maybe 16 sided? I'd also like to increase the smoothness if I want, up to, say, 120.
*   **Overall size**: It would be nice to have a parameter to scale up or down the whole thing at once. Maybe base everything off an ID of 10, with a scale factor to make it bigger, since the starting size is a little small?

I'm not trying to make money off this, so it'll be under a creative commons share alike non-commercial license for personal or group use, if that helps.

I'm not looking for a specific font or anything like that at this point. I just want to be able to make the basic design and change the above parameters.

I don't think I need any special libraries or anything. Standard OpenSCAD should work, I think. Let me know if you have any questions!

Hey, I'm looking to generate some hose adaptors using OpenSCAD. I've got some different sized hoses I need to connect and I'd like to make the adaptors parametric, so I can easily customize them for different diameters.

Here's the basic idea: I need a cylinder on top, a cylinder on the bottom, and then a connecting section that smoothly transitions between the two. The user should be able to specify the diameter and height of each of these sections, plus a few other parameters.

Specifically, I need these variables to be customizable:

*   `$fn`: to control the smoothness of the curves. I should be able to set this from 1 to 360, with a default of 200.
*   `fit`: this controls how tight the fit between the hose and the adaptor will be. A good default would be 0.5 mm for a snug fit.
*   `wallThickness`: obviously, how thick the walls are of the adaptor.
*   `topSectionSize`: the outer diameter of the top section.
*   `bottomSectionSize`: the outer diameter of the bottom section.
*   `topSectionHeight`: the height of the top section.
*  `midSectionHeight`: the height of the middle, transition section.
*   `bottomSectionHeight`: the height of the bottom section.

The internal diameter of the adaptor sections should be calculated by subtracting `fit` and `wallThickness` from the section diameters.

I'd like the middle section to be a frustum, a cone with the top cut off, so it can smoothly connect the different diameters of the top and bottom sections.

Could you generate the OpenSCAD code for me?

[Assistant]
MyAdaptors.scad:
```

$fn=200;

fit = 0.5;
wallThickness = 2;

topSectionSize=63;
bottomSectionSize=100;

topSectionHeight = 50;
topOuter = topSectionSize-fit;
topInner = topOuter - wallThickness;

bottomSectionHeight = 50;
bottomOuter = bottomSectionSize - fit;
bottomInner = bottomOuter - wallThickness;

midSectionHeight = 50;

section(bottomSectionHeight,bottomInner,bottomOuter);  // Bottom section

translate([0,0,bottomSectionHeight]) angleSection(midSectionHeight,bottomInner,bottomOuter,topInner,topOuter); // joining piece

translate([0,0,bottomSectionHeight+midSectionHeight]) section(topSectionHeight, topInner, topOuter); // top section

module section(height=50, inner=63, outer=65) {

	difference() {
		cylinder(h=height,r1=outer/2,r2=outer/2);
		cylinder(h=height,r1=inner/2,r2=inner/2);
	}

}

module angleSection(height=50, startInner=101, startOuter=105,endInner=10,endOuter=20) {

	difference() {
		cylinder(h=height,r1=startOuter/2,r2=endOuter/2);
		cylinder(h=height,r1=startInner/2,r2=endInner/2);
	}

Hey there! I'm looking for an OpenSCAD design to help visualize 3D printing settings, and I've got a pretty good idea of what I want, but I'm not great at the code. I saw something similar online but want a few changes.

Basically, I want to create a set of customizable cubes that can be labeled, and then I can print them with different settings. This way, I'll have a physical library of what different settings look like.

Here's what I'm thinking:

**Core Design:**
*   **Cube:** The main part is just a simple cube. I want to be able to easily change the size of the cube using a variable.
*   **Label:** I need to be able to add text labels on one face of the cube. I'd like to control the text itself, the font, and the font size. Also, the font depth.
*   **Parametric:** All of the parameters should be easily adjustable in OpenSCAD.

**Specifics:**
*   **Text Placement:** The text should be centered on one of the cube's faces. It should be extruded outwards so that it's easy to see.
*   **Font Options:** I'd like the option to choose different fonts; I know OpenSCAD supports that. Also, being able to choose bold, italic, etc. would be nice.
*   **Variables:** Here are the variables that I need to be able to set:
    *   `cubeSize` (the side length of the cube in mm)
    *   `Label` (the text string for the label)
    *  `fontSize` (the size of the font)
    *   `fontType` (the font family and style)
   *   `fontDepth` (how far to extrude the text from the face of the cube)

**Libraries:**
I don't think I need any special libraries for this but please let me know if you need to use any.

**Output:**
I want a single OpenSCAD file that generates the cube and the text label.

The idea is that I'd print a bunch of these cubes, changing the infill pattern, density, wall count, etc. and the text will describe what settings I used. Then, I'll have a physical reference.

Do you think you can help me with this? Let me know if you have any questions.

I'm looking to create a parametric model rocket display stand, and I'd like to have a bit more flexibility in the design than I've seen so far. I'd like to be able to adjust not just the overall diameter, foot count, engine diameter, and engine depth, but also the shape and size of the "feet" and the central support.

Here's what I'm thinking:

**Overall Structure:** The stand should have a circular base with multiple feet radiating outwards, with a central cylindrical support to hold the rocket.

**Base:**
*   **Step Diameter:** This is the diameter of the circle on which the feet are positioned, as in the existing design.
*   **Foot Count:** The number of feet, like in the existing design.
*   **Foot Shape:** I'd like to have a few different options here:
    *   **Option 1: Rounded Rectangle (similar to original):** This would be a rectangle with rounded corners, similar to what's in the provided file, but I'd like to control the rectangle's dimensions (length, width) and the corner radius.
    *   **Option 2: Triangle:** A simple triangle, where I can control the base and height.
    *   **Option 3: Custom Polygon:** The ability to specify the points of a polygon for a custom foot shape.
    *   **Foot Height:** The height of the "feet" at the base.
*  **Foot Base Offset:** The ability to control the vertical offset of the base shape from the bottom. This could be zero for the foot to start at the bottom or a positive value for the base to start above the bottom.

**Central Support:**
*   **Engine Diameter:** The inner diameter of the support where the rocket will sit.
*   **Engine Depth:** The depth of the cylindrical support, as in the original.
*   **Support Wall Thickness:** The thickness of the central cylinder wall.
*   **Support Base Diameter:** The diameter of the cylinder that is at the bottom of the support structure. This will usually be larger than the engine diameter, and its height should be adjustable.
*   **Support Base Height:** The height of the cylinder that is at the bottom of the support structure.

**General Requirements:**
*   The design should be parametric so that all the dimensions can be easily changed.
*   Use the `rotate_extrude` function for the central support with variable segments, so that it looks like it has some vertical lines as opposed to being a smooth cylinder. Also, use `rotate_extrude` to create the feet if the user selects a triangle or rectangle.
*   I'd like the design to be easily customizable so that users can create stands for a wide variety of rocket sizes and shapes.
*   Please include comments in the code to explain what each parameter does.
*   I don't need to deal with fillets at this time, but having that ability later would be a bonus.

I don't think you'll need any special libraries to achieve this.

Could you generate an OpenSCAD file for this? I'd be happy to iterate and provide more guidance as needed.

I'm looking to design a small, customizable PCB vice for holding circuit boards while I'm working on them. I've seen some versions that use rubber bands for tension, and I'd like to create something similar that I can adjust to fit different board sizes. I've got some specific design ideas in mind, so let me walk you through it.

First off, the vice will consist of two main parts: a base and two identical blocks that slide along the base to hold the board. I'd like to be able to specify the overall length and width of the base, as well as its thickness. I'll also need to specify a corner roundness for the base.

The base will have a slot cut into it where the blocks slide along; for this slot, I need to be able to define its top width, bottom width, and height. There should also be a tolerance setting for this slot in case the block is too tight or too loose, as well as a padding around the slot to create a smooth surface before the main cutout, and a small wall at the edge of the base to protect the slot. I'm expecting to set this up so that the slot is in the center of the base, if that wasn't clear.

For the block, I need to be able to define its height, top and bottom thickness, as well as padding that separates the slot from a cutout for the PCB. There should also be a rubber band slot with adjustable depth, height and offset from the base of the block. Finally, there should be a cutout for the PCB itself, with adjustable Z offset from the top of the block, depth, and outer height.

Ideally, I'd like to have a single OpenSCAD file that defines all of these parameters and generates the base and block as separate pieces, and then another that outputs both of those pieces together. I'd like to be able to choose whether to render just the base, just the block, or both. I think if you could include comments to make clear which parts are being defined in each section, that would help a lot. Also, can you make sure all the calculations are done in the code as well, so I don't have to calculate things like the slot cutout diameter?

I don't have any special library requirements - everything should be achievable with standard OpenSCAD features.

Hi, I'm looking for a parametric OpenSCAD design for a toilet paper holder. I'd like it to have a few specific features, and I’m hoping you can help me create a flexible design that I can easily modify using parameters.

The holder should consist of two main parts: a wall-mounted backplate and an arm that holds the toilet paper roll, also acting as a small shelf.

**Backplate:**

*   It should be rectangular with rounded corners.
*   The backplate should have a small lip that juts out near the top, perpendicular to the wall, creating a surface for a shelf.
*   I'd need parameters to control the overall width and height of the backplate, the radius of the rounded corners, and the thickness of the backplate material.
*   I will also need to control the lip height and depth.
*   For simplicity, I’d like the backplate to be a single extruded shape

**Arm/Shelf:**

*   The arm should start with a straight segment extending from the side of the backplate.
*   It should then smoothly curve downwards and continue as a horizontal cylindrical rod for holding a roll of toilet paper.
*   After the rod there should be another curve upward, followed by a short straight segment.
*   I want to control the radius of the arm itself, the radius of the curved section, the length of the straight segments of the arm, the height at which the arm starts from the backplate, and the overall depth of the horizontal rod.
*   I’d like to have a parameter to adjust the curve angle of the two curved segments.

I’d prefer to have the design use modules so that parts can be reused. It should be easy to modify the design using parameters so I can make adjustments if I find the physical model is not ideal. I'm not using any special libraries, but I’m fine if you want to use them.

Thanks!

I'm looking to create a parametric design in OpenSCAD based on Robert Fathauer's "Walk Torus83 Fort." The core idea is a fortified enclosure where the walkway follows an (8,3) torus knot, which creates an octagram shape with 16 crossings. I've included a sample OpenSCAD file I was experimenting with which may give you a better idea. I want to be able to control the overall size, wall thickness, height, and number of supporting "blocks" on the base, as well as how many steps are in the staircases.

Specifically, I envision the following:

*   **Torus Knot Walkway:** The walkway should form an (8,3) torus knot. This should visually create the octagram described, with crossings. The walkway should have a defined width and height.
*   **Wall Rafts:** The walkway will have supporting "wall rafts" at the base, which are like blocky supports. I want to be able to specify the number of these blocks and their dimensions relative to the overall length.
*   **Towers:** There should be towers located at the intersections of the octagram shape. These should be cylindrical with a spherical top. Their size should be customizable relative to the other dimensions.
*   **Stairs:** Each walkway section should have stairs leading up and down. The number of steps should be adjustable as a parameter.
*   **Doors:** There should be stylized "doors" on the walkway. I don't need them to be functional, just visual. They should follow the style in the sample file.
*   **Parameters:** I'd like to be able to control the following parameters:
    *   `leng`: Overall length/scale of the structure.
    *   `thickness`: Thickness of walls and walkway.
    *   `height`: Overall height of the fort.
    *   `bk_number`: Number of base blocks supporting each "raft."
    *   `stair_number`: Number of steps in each staircase.
    * `walkway_only`: a boolean parameter that lets me toggle doors on all walkways. If set to true, the doors are present on all walkways, if false the doors only exist on the main walkway.
*   **Modular Design:** It would be great if the design could be broken down into modules for better organization, like in the example file.

I'd like the design to be entirely parametric so I can easily tweak it for different sizes and shapes. I don't need any specialized libraries, standard OpenSCAD should be enough. I've attached the sample file. Please generate all of the .scad files necessary.

I'm looking for some help creating a customisable funnel design for 3D printing, specifically for use with resin bottles and filter papers. I have a sketch in mind, and the critical part is that it needs to be parametric so I can easily adjust it to fit different bottle sizes, filter paper diameters, etc.

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

*   **Funnel Angle:** The angle of the funnel walls, in degrees.
*   **Funnel Height:** The overall height of the funnel section.
*   **Spout Outer Diameter:** The outside diameter of the spout that fits into the bottle opening.
*   **Spout Height:** The length of the spout.
*   **Collar Inner Diameter:** The inside diameter of the collar at the top, meant to hold the filter paper (and be a wide opening).
*   **Collar Height:** The height of the collar section.
*   **Wall Thickness:** The thickness of the funnel walls.

I’d like it to be a rotationally symmetric design; in my mind, the most efficient way to do this would be using `rotate_extrude()`. I'm imagining a 2D profile that gets rotated to form the 3D funnel. The profile will have the main cone shape of the funnel, then a straight cylinder for the spout, then a short vertical section joining the funnel to the wide collar, then the wider collar with its own short vertical section, with each section joined with hulls. The values of the parameters will need to inform all of this.

I'd also like to be able to control the `$fn` value for polygon resolution. This would allow me to adjust print quality in settings.

Could you create an OpenSCAD file that implements this design, using the parameters I've provided? I would prefer to keep all code within one single file.

Hey, I'm looking to design a parametric container, specifically for hex bits but it could be used for other small cylindrical objects. I need it to have a threaded lid.

Here are the details:

*   **Hex Bit Sizing:** The container needs to accommodate hex bits of varying sizes. The critical dimension is the flat-to-flat measurement of the hex bit plus some clearance. I'll need to specify the bit size and clearance as parameters. Common bit sizes are 4mm and 6.9mm.
*   **Hex Cell Structure:**  The container body should have an internal hexagonal grid to hold the bits. This grid should be customizable in terms of the wall thickness between the hex cells and how many layers out from the center it extends.
*   **Container Walls:** I'll need to control the thickness of the outer container walls separately from the hex cell walls.
*  **Threaded Lid:** The lid will need a trapezoidal thread that fits securely on the container body. I need to be able to set thread parameters like pitch, thread height, and clearance. I'll be using an acme style thread and need to be able to set the thread angle as well.
*   **Nubs:** Both the lid and the body should have small nubs or posts that provide some friction and alignment when closing the container. These should be configurable in number, size, and depth.
*   **Grid Toggle:** I'd like to be able to switch between a hex grid and a simple cylinder for the inner structure of the container, in case I want to store items other than hex bits, like hotend nozzles.
*   **Rounding:** A bevel or round on the top edge of the container and the lid would be nice.

I'd like a fully parametric OpenSCAD design, where all the dimensions described are set via variables. I'm also using a couple libraries: *MCAD* for the threads and *BOSL* for anything else you might need to make the design. Can you provide me with the necessary code?

[User]
I need an OpenSCAD design for customizable filament swatches. I want to be able to label them with information about the filament, and also use them to test print quality. The swatches should have a rectangular base with rounded corners.

Here's what I need to be able to configure:

*   **Text:**
    *   Three lines of text: one at the top (larger font), one at the bottom left, and one at the bottom right.
    *   A fourth line of text on the top edge of the swatch, to quickly identify material type when stored in a box.
    *   Font, font size (separate settings for the main text and the thickness steps text), text line distance
    *   Option to have the main text raised or embossed (cut into the base).
*   **Thickness Test:**
    *   A series of steps with increasing thickness, labeled with the thickness.
    *   The option to specify the thickness progression as a list of values, and also be able to include a negative value which will generate a "bridge" feature of that thickness
    *  Text to label the thickness steps, with a configurable text height.
*   **Test Patterns:**
    *   The option to include a set of test patterns for evaluating print quality (overhangs, bridging, circles, pyramids, etc.) I need to control how many circle test patterns are included.
    *    These patterns should include a small sphere test, a hole/cylinder test (with a small square area cut from its side), an overhang test, a hanging cylinder test, and a pyramid test.
*   **Swatch Dimensions:**
    *   Swatch width, height, and thickness
    *   Rounding radius for the corners
    *   Border size around the text
    *   Diameter of a hole for hanging, with a default
    *   Radius of side indents/grooves for easier removal from a storage box
*   **Fonts:**
    *   Use the standard OpenSCAD `text()` module. The font should be configurable. The default should be "Pathway Gothic One", and the code should work when running OpenSCAD on my PC using **Aldo** as the font. I should be able to pick from Google Fonts in a customizer, like the list on http://www.google.com/fonts

I need this to be parametric so I can adjust it for different filament types. I'd like a single OpenSCAD file that contains everything.

Also, please use comments to clearly explain the different parts of the code. I'd like to understand how it works.

Configurable_Filament_Swatch_VL.scad:
```
//upper text line
textstring1="Basicfil PLA";

//Set font size in mm
textsize_upper=5;

//Left lower text line, e.g. for layer thickness, print temperature
textstring2=".2  210C";

//Right lower text line, e.g. for the color of the filament
textstring3="Orange";

//Set font size in mm
textsize_lower=5;

//Set font size on the thickness steps in mm. These show the step size below (0.2, 0.4, ...). Set it to zero (0) to remove the text
textsize_steps=5;

//Top text (on the top edge, to quickly find the material type).

//Font name, e.g. "Pathway Gothic One,", "Voltaire", "Oswald", depends on what is available on the platform. In the customizer,choose from about 700 Google Fonts. For an overview please refer: http://www.google.com/fonts. If you run OpenSCAD on your own PC, use **Aldo** as font.

[User]
I want to create a customizable name tag for my bowling ball bag, and I'd like the design to be in OpenSCAD. The name tag should have a triangular column shape, with text wrapped around the three sides of the triangle, and loops on the top and bottom for attachment.

Specifically, the main body of the name tag should be a triangular column created by hollowing out a solid triangular prism, leaving a defined edge. This hollowed-out structure will define the tag's overall shape and thickness.

The text should be positioned on the three sides of the triangle, one line of text per side. This means it should wrap around the main triangular column. The text should be able to be changed by the user, and I'd like to be able to adjust the font, font style (like bold or italic), and size.

For the attachment, I want to have simple cylindrical loops at the top and bottom, sticking out from the main body. These should also be configurable, and I would like them to be located on the center of the top and bottom of the triangle.

I'd like the following parameters to be customizable by the user:

*   `height`: The overall height of the tag.
*   `r`: Radius of the outer triangle (used to define the triangle's size).
*   `R`: Radius of the inner triangle (used to define the hollowed out space and the edge thickness).
*   `text1`: The first line of text for one face.
*   `text2`: The second line of text for the next face.
*   `text3`: The third line of text for the last face.
*   `font_name`: The name of the font.
*   `font_style`: The style of the font like "Bold" or "Italic."
*   Loop Diameter: The diameter of the top/bottom loops.
*   Loop Height: The height of the top/bottom loops.

I'm hoping to use standard OpenSCAD functions for this design, so I don't think I need any libraries. I would like the font to be able to use Google fonts, or if not, at least a wide variety of fonts available by default in OpenSCAD. I'd appreciate a well-commented SCAD file with those parameters at the top.

Hi there! I'm looking to create a parametric cable management box, kind of like the one described [here](https://www.thingiverse.com/thing:3421512) but I want it to have a few more options and be totally customisable, including a cable slot feature. I'd like it to be in OpenSCAD.

Essentially, I need a box with a variable number of sides (3 to 8), which will control whether it's a triangle, square, hexagon, etc. I want to be able to specify the diameter, the depth, a corner radius for those curved edges, and the thickness of the walls. I also want to have a lid for the box.

I'd also like to have an option for a central post in the box, for cables to wrap around. And finally, it should have some slots around the outside of the box, so that cables can exit the box when the lid is on.

The code in the link has a working example but I need more granular control than I can achieve by changing the existing parameters.

I'm okay with you generating multiple .scad files. I don't need any specific libraries, but please let me know which ones you use, if you use any.

Thanks!

Hey there, I'm looking to create a customizable riveted plate using OpenSCAD, and I'd really like your help designing it. I've seen some examples, but they aren't quite what I want.

Here's what I'm envisioning:

First, the plate itself needs to be a simple rectangle. I need to be able to control its width and height, so let's make those parameters `width` and `height`. I also want a small thickness parameter, let's call that `plateThickness`.

Then, I need to add rivets around the edges. For that, I'll need these parameters:
*   `rivetsOffset`: the distance of the rivets from the edges. This will be constant on all edges
*   `RightRivets`, `LeftRivets`, `TopRivets`, and `BottomRivets`: these should act as boolean flags, with a '1' representing true and a '2' representing false (e.g. 1 = rivets on that side, 2 = no rivets on that side).
*   `TpRivetsSize`, `BtmRivetsSize`, `LRivetsSize`, and `RRivetsSize`: The size of the rivets on each side (Top, Bottom, Left, and Right).
*   `TpRivets`, `BtmRivets`, `LRivets`, and `RRivets`: the *number* of rivets on each side.

For the rivets themselves, they need to be a cylinder with a sphere on top. The cylinder should be relatively short, and then the sphere will be added on top. I also need control over the number of faces used to represent a cylinder or sphere using a parameter named `rivetDetail`. A value of 4 would make them square instead of circular.

To make it more robust, please ensure the code takes into account the situations where there would be no rivets on one or more sides, and that the rivets are positioned correctly according to the calculated values. I'd also prefer that the code not utilize the difference() call to cut the corners, and instead to construct the base plate from just one cube (or linear_extrude), if possible.

Let me know if you have any questions. I'm excited to see what you come up with.
