Hey there, I'm looking to design a set of parametric joints for building bamboo trellises and plant cages. I've seen some examples online, but I want to be able to customize the dimensions for different bamboo sizes and cage shapes.

Here's what I'm hoping to achieve:

*   **Joint Type:** I need a joint that can connect horizontal bamboo pieces to vertical ones. Think of it like a multi-way connector.
*   **Parametric Design:** I want to be able to control these parameters:
    *   `sides`: The number of sides for the trellis/cage. It should handle values from 1 (L-bracket), 2 (T-bracket), and then 3-10 for polygonal cages.
    *   `diaH`: Diameter of the horizontal bamboo pieces in millimeters.
    *   `diaV`: Diameter of the vertical bamboo pieces in millimeters.
    *   `shell`: Thickness of the connector shell in millimeters.
    *   `collarH`: Height of the zip tie collar above the shell.
    *   `collarW`: Width of the zip tie collar
    *   `lengthV`: Length of the vertical connector part in terms of the diameter of the vertical bamboo piece.
    *   `lengthH`: Length of the horizontal connector part in terms of the diameter of the horizontal bamboo piece.
    *   `screwH`: Position of the screw hole on the horizontal part of the connector, as a percentage of the horizontal part length.
    *   `screwV`: Position of the screw hole on the vertical part of the connector, as a percentage of the vertical part length.
    *   `diaScr`: Diameter of the screw hole in millimeters.
    *    `fudge`: A fudge factor to adjust the horizontal part separation in mm.
    *   `wrapV`:  Adjust the vertical tube wrap (percentage value).
    *   `wrapH`: Adjust the horizontal tube wrap (percentage value).

*   **Shape:**
    *   For polygonal cages (sides 3-10), the joint should have the appropriate angle to form the polygon.
    *   For `sides = 1`, it should be an L-shaped bracket.
    *   For `sides = 2`, it should be a T-shaped bracket.
*   **Features:**
    *   The joint should have a collar at the ends for zip ties, which should be parametrically adjustable.
    *   There should be a screw hole for securing the bamboo using a screw (or wire). The position and diameter should be adjustable.
    *   The horizontal pieces should adjust their vertical position for wrap adjustment and to provide vertical separation between the ends of the horizontal sections.
    *   There should be a way to adjust how much of the vertical piece of the bamboo is covered by the joint using parameters.
*   **Libraries:** I'm not really sure what libraries might be helpful, so if you have a suggestion for that, let me know.

I’d like the design to be robust enough for outdoor use and 3D printing. Could you generate an OpenSCAD file or files that can achieve this? Let me know if you need any more details.

Okay, I'm looking to create a customizable label for my Harbor Freight Apache cases. I have a few different sizes, so I need a design that can be adjusted parametrically for each. I've seen a few designs out there, but I'd like to make my own.

The label should have a rounded rectangular shape with customizable dimensions for length and width. It needs to be able to fit on the different cases, particularly the 1800 model which is smaller. I'd like to be able to specify the radius of the rounded corners as well as the overall thickness/height of the label.

I want to be able to add up to three lines of text, and each line should have its own independent text input field. I need control over the font, font size, and how much the text protrudes or is recessed into the surface of the label. This last parameter is important to me - I want to be able to either have the text raised or engraved.

For the font, I'd really prefer to use Google Fonts if possible. It would be great if the design could use whatever fonts are supported by OpenSCAD, or even better, specify a particular Google Font by name and potentially style (like "Orbitron:Bold 700").

So to summarize, I need a parametric OpenSCAD design with:

*   Adjustable length, width, and corner radius
*   Adjustable thickness of the label.
*   Up to three customizable text lines
*   Adjustable font, font size, and text depth (either recessed or raised).
*   Support for Google Fonts if possible.

The parameters for the different Apache cases are as follows (as best as I can tell):
*   Apache 1800: Length: 67, Width: 40, Corner Radius 2.5, but the corner radius might need to be adjusted if it doesn't fit well
*   Apache 2800, 3800, 4800, 5800 and 9800: Length: 85, Width: 50, Corner Radius 7.5 (for these models, the radius may also need slight adjustments)

I think that should cover everything!

I'd like a parametric OpenSCAD model of a Cherry MX-style mechanical keyboard switch. I'm looking for something that is highly customizable so I can tweak its dimensions for my own purposes, and also be able to turn various features of it on or off for debugging and easier viewing, similar to what I've got going on in the code I'm pasting below, but, you know, *good*.

I want the following features to be parametrically controlled:

*   **Overall Dimensions:**
    *   Width, Length, and Height of the main switch body
    *   Thickness of the top and bottom housings
*   **Stem:**
    *   Dimensions of the stem's central tab and base
    *   Ability to enable/disable the stem
    *   Ability to specify stem color
*   **LED:**
    *   Dimensions and location of the LED component (both the base and the "bulb" part)
    *   Dimensions and location of the LED legs
    *   Ability to enable/disable the LED
    *   Ability to specify the LED's color and the color of the legs
*   **Top Housing:**
    *   Overall dimensions and shape (including a trapezoidal profile)
    *   Cutout for the LED, and a general cutout in the front
    *   Cutout for the stem
    *   Cutout for the LED legs
    *   Ability to enable/disable the top housing
    *   Ability to specify its color
*   **Bottom Housing:**
    *   Overall dimensions and shape (including a stepped profile)
    *   Cutout for the LED legs
    *   Dimensions and placement of mounting tabs on the bottom
    *   Ability to enable/disable the bottom housing
    *   Ability to specify its color
*   **Plate Mount:**
    *   Dimensions and placement of the plate mounting tabs
    *   Ability to enable/disable the plate mount
    *    Ability to specify the color
*   **Guides:**
    *   Dimensions and placement of the cylindrical guides for mounting the switch onto a PCB
    *   Ability to enable/disable the guides
    *   Ability to specify its color
*   **Pins:**
    *   Dimensions of the pins
    *   Placement of the pins
    *   Ability to enable/disable the pins
    *   Ability to specify pin color
*   **Color:**
    *   Each component should have a separate color parameter

I'd really like all of these parameters exposed in the Customizer so they're easy to adjust. Also, I'd prefer if the model used the `hull()` operation and did not include any hard-coded dimensions. I'm also going to want to use this with some of the other libraries at some point, so if you could write it to play nicely with `BOSL` or `BOSL2` I'd really appreciate it. If it helps for you to see the kind of thing I'm aiming for, this is the code I'm starting with:

```openscad
//Detail Of Round Parts
$fn=30;
enableStem = true; // [true, false]
stemColor = "DodgerBlue";
enableLED = true; // [true, false]
ledColor = "Crimson";

topColor = "DimGray";
enableBottom = true; // [true, false]
bottomColor = "DimGray";
enablePlate = true; // [true, false]
plateColor = "Black";
enableGuides = true; // [true, false]
guideColor = "White";
enablePins = true; // [true, false]
pinColor = "Gold";

Hi! I'm looking to create a parametric cable management system similar to Kart5a's "Cable Claw" but with some additions. I have some scad code for the ball stops and a brief description but I'd like to have the entire system be parametric. I'd like to be able to adjust the dimensions of the base, the claw, the dovetails and the ball stops.

The system is intended to have a base that can be mounted to a surface using screws or double-sided tape. The base has a female dovetail that accepts a "claw" piece, which has a male dovetail that slides into the base. The claw piece will have holes for ball stops. The ball stops I want to be parametric (I have an example in my original prompt) so you can vary the size for different cables. These ball stops will be used to hold cables in place on the claw. I'd like to avoid needing to provide a bunch of different sizes, which is why I'm asking for everything to be parametric. I'm not worried about the mounting of the base - it can be assumed there are either holes for countersunk screws or a flat area for double-sided tape.

I'd like the following parameters to be adjustable:

**Base Parameters:**
*   `base_length`: Overall length of the base.
*   `base_width`: Overall width of the base.
*   `base_height`: Height of the base.
*  `base_screw_hole_dia` : Diameter of the mounting holes for screws (if there is a double-sided tape option we can skip adding specific parameters for that)
*  `base_screw_hole_offset`: Offset distance of the mounting holes from the edges of the base
*  `base_dovetail_width`: Width of the dovetail feature in the base.
*  `base_dovetail_depth`: Depth of the dovetail feature in the base.
*  `base_dovetail_angle`: Angle of the dovetail.

**Claw Parameters:**
*   `claw_length`: Overall length of the claw.
*   `claw_width`: Overall width of the claw.
*   `claw_height`: Overall height of the claw.
*  `claw_dovetail_width`: Width of the male dovetail on the claw.
*  `claw_dovetail_depth`: Depth of the male dovetail on the claw.
*  `claw_dovetail_angle`: Angle of the dovetail.
*   `claw_ball_stop_spacing`: Spacing between the holes for the ball stops on the claw.
*   `claw_ball_stop_offset`: Distance from the edge of the claw to the first hole.
*   `claw_ball_stop_hole_dia`: Diameter of the holes for the ball stops.

**Ball Stop Parameters:**
*   `stop_dia`: Diameter of the ball.
*   `cable_dia`: Diameter of the cable or strain relief opening.
*   `slot_width`: Width of the slot.
*   `bottom_flatness`: The amount of the ball stop cut off at the bottom (flatness)

I would like to have a separate module for each of the pieces, so that they can be included and used independently if needed.
*   `module base()`
*   `module claw()`
*   `module ball_stop()`

I'd like the base and claw to use the same dovetail angle parameter (`base_dovetail_angle` and `claw_dovetail_angle` should share a single value for the overall system). Also, the claw male dovetail should be slightly smaller than the base female dovetail for a snug fit. I think this should be an offset that can be added to the claw dovetail parameters to reduce their size. Lets call this `dovetail_fit_tolerance`.

I'm thinking we can use the `linear_extrude` to handle the dovetail and then use the built-in `difference()` and `intersection()` to create the dovetail feature.

For the ball stop, I've already created most of it:
```
difference(){
    sphere(d=stop_dia,$fn=100);

    // make slotted hole
    cylinder(d=cable_dia,h=stop_dia,center=true,$fn = 50);

    translate([0,stop_dia/2,0])
    cube([slot_width,stop_dia,stop_dia],center=true);

    // cut off bottom
    translate([0,0,-stop_dia/2])
    cube([stop_dia,stop_dia,bottom_flatness],center=true);
} //end difference
```

I'd prefer to have a single file that contains all of these modules for ease of use.

Also, I'm not using any custom libraries, just the standard OpenSCAD features. I am happy to install some if necessary though.

Can you provide the OpenSCAD code for this?

Hey, I'm looking to create a fruit fly trap that fits onto a standard Mason jar lid. I've seen some designs online, and I've even tried making one myself, but I'd love a version that's a bit more customizable. Basically, I want to 3D print a lid with a cone-shaped opening in the center that guides the flies down into the jar.

Here's what I'd need to be adjustable through customizer settings:

*   **Jar Size:** This should have options for "regular mouth" and "wide mouth" Mason jars. I know the standard diameters are about 60mm and 76mm respectively, but maybe you could include a little wiggle room in the code for tolerance.
*   **Top Opening Diameter:** The diameter of the cone opening at the top should be adjustable. I'm thinking a range of about 10mm to 40mm should be good.
*   **Cone Height:** I'd like to be able to adjust how tall the cone is. A range of maybe 10mm to 40mm would work for this.
*   **Bug Entry Hole Diameter:** The diameter of the hole at the bottom of the cone (where the bugs actually enter) needs to be adjustable too.  It should range from 1mm up to 10mm so I could use this as a housefly or bee trap too.

I'm thinking the model should basically be a disk that sits on top of the jar, with the cone sticking up. You'll need to take into account the jar's threads, so perhaps a bit more of a lip on the inside of the lid. I'd like to be able to print it in one piece.  I have OpenSCAD, so that's the format I need it in. I’m not sure if it is relevant but I tried using a customizer website in the past with other designs, and it didn't seem to work.

I'm also thinking that it's probably best to define the jar size internally. Could you do that using constants, as well as calculating the Inner diameter of the jar to account for that wiggle room I mentioned? That would probably be helpful. I'm not an expert on OpenSCAD so it's just a suggestion.

Finally, could you try to keep the code relatively clean and easy to understand? That would be greatly appreciated. Thanks!

I'd like a parametric OpenSCAD design for a customizable QR code tag or keyring. It should allow the user to import an SVG of a QR code, and then generate a 3D printable tag with various options for the size, thickness, and keyhole type.

Here's what I need it to do:

**QR Code Import:**
*   The design needs to import an SVG file for the QR code.
*   There should be options to rotate the QR code within the tag.
*   An option to disable the QR code entirely is useful.

**Size and Shape:**
*   The user should be able to set the overall size in millimeters (mm). The size should be adjustable so that the width of the small cubes in the QR code is a multiple of the user's slicer line width. If the slicer line width is not set, the size will be equal to the value the user sets.
*   There should be separate parameters to control the code height and the base height of the tag.
*   Rounded corners for the tag are important.

**Keyhole Options:**
*   Several different keyhole types are needed: none, a slot, a squared slot, a circular hole, an alternative circular hole, a minimal circular hole, a circular hole in a corner, and an alternative circular hole in a corner.
*   I need an option to enable a keyhole cutout on the top layer.
*   The size of the keyhole opening and the space around the keyhole are also needed as parameters.
*   A way to adjust the vertical position of the keyhole is a must.

**Text Options:**
*   The ability to add text above and below the QR code is necessary. This should use multiple lines of text.
*   A font parameter and a text size parameter are required.
*   Text alignment (left, center, right) is required.
*   There needs to be a character spacing parameter.
*   Custom line spacing should be an option.
*   Text direction and language settings are a good idea.
*   The ability to nudge the text horizontally and vertically is necessary.
*   An option to set different fonts for individual lines would be useful.

**SVG Logo Options:**
*   The design should also allow for importing an additional SVG logo.
*   I need parameters to scale, move, and rotate the logo.

**Extra Space:**
*   I'd like options to add extra space above, below and on the sides of the QR code and text.

**Holder Options:**
*   The design should include an option for a holder or a frame for the tag.
*   I need a parameter to enable the card to be previewed while the holder is being viewed.
*   An option for the holder to have a window cut out on the front, or on both front and back is needed.
*   Parameters for the base height, the base feet width, and wall height/thickness of the holder.
*   I need the ability to adjust the space between the card and the walls of the holder.
*   Rounded corners on the holder are necessary.
*   An option to adjust the height of the holder based on if extra text height is being used.

**Advanced/Multi-Color:**
*   The ability to offset the code for multi-color printing is needed.
*   An option to move the card to the center or bottom-left corner is needed, for easy measurement.

**Preview Settings:**
*   The design should have customizable colors for the base, code, multi-color invert, holder and text (where applicable) previewing purposes.

**General:**
*   The design should use the `text()` module to render the text.
*   The design should calculate sizes using the default sizing of the imported SVG.
*   I'd like the option to export either the card or the holder separately.

I think that covers everything. I look forward to seeing what you come up with!

=======Instructions=======

---1. Create the QR Code---
- Go to here - https://www.qrcode-monkey.com/
- Only change the Content settings, DO NOT change the colors, etc
- Click Download PNG and wait for the file to download

---2. Convert the downloaded JPEG file to an SVG---
- Go to this site - https://convertio.co/jpeg-svg/
- Drag the PNG file into the window
- Click Convert. When it's finished, click download
Note: I'm aware you can download the code as a SVG file from the first site, but this will not be formatted properly for our uses.

---3. Customize---
- Put the SVG file in the same folder as this SCAD file
- Click Window, then untick Hide Customizer
- Enter the SVG name under Basic Settings, then customize the settings

---Notes:---

- Raised and Cut-Out are for changing filament at layer height. You can also set the base/code height to 0 and export each part
- Multi-color and Code are to be used together for inlay/multi-color printers
- If you want to print a double sided tag, you can set Base Height to 0 and export the second side. Then just flip this over in the slicer

=======Changelog=======
V1.2
- Option to add space to sides of the QR code

V1.1
- Added SVG logo import
- Fixed text spacing

V1
- Initial release
--------------

Internal build - v0023

/* Scale by size
The code works based on the fact that the exported QR codes are always the same size. If you want to use a different service to generate the QR codes, you can set these values. To work them out, run the following code in a new document:

    size = 100;
    linear_extrude(1) square(size);
    translate([0,0,1]) linear_extrude(1) offset(0.001) import("exported_svg_name.svg");

Make sure the size value is larger than the QR code itself. Render and export this as a STL then take the measurement using some other software

default_border_size is the size from the left edge of the square to the left edge of the QR code
default_qr_size is the height or width of the QR code itself (without the border)
default_cube_size is the height or width of the smallest cube/pixel in the QR code (only used if Line Size value is set)

I'd like to create a parametric cable hanger for 3D printing. I've got a few specific ideas in mind, and I'd like it to be customizable.

First, the hanger should have a flat backplate that mounts to the wall, and from that backplate, a series of "fingers" will extend outward to hold the cables. I need the design to be flexible so I can easily change the number of cables it holds. Here are the parameters I'd like to be able to control:

*   **`width_mm`**: The overall width of the hanger.
*   **`cable_d_mm`**: The diameter of the cables that will be held by the hanger.
*   **`slot_s_mm`**: The spacing between each cable slot on the hanger.
*   **`slot_e_mm`**: The extension of the finger from the backplate - basically the length of the fingers that hold the cables.
*   **`back_h_mm`**: The height of the backplate.
*   **`t_mm`**: The thickness of the backplate and the cable holding fingers.
*   **`screw_r`**: The radius of the mounting screw holes.
*  **`$fn`**: The number of fragments to be used for generating curved surfaces.

Essentially, the design should look similar to the file I'm including, but I need it to be written from scratch. I'd like the design to automatically calculate the number of slots based on the `width_mm`, `cable_d_mm` and `slot_s_mm` parameters and space them evenly along the width of the hanger with a little offset on each end. The backplate should have mounting holes on either side. The slots should be round at their base (where the cable sits). The main functionality will come from using the `back()`, `comb()`, and `holes()` modules within the `hanger()` module. And please use `difference()` to subtract the comb and hole modules from the back module.

I'm not using any special libraries, so you don't need to worry about including any specific `.scad` files. Could you generate the OpenSCAD file for this design?

Hey, I'm looking for help creating a parametric ring generator in OpenSCAD. I'd like the basic ring band to be a simple torus shape, but with a flat top and bottom. I want to be able to control the inner diameter using a size that's roughly equivalent to standard US ring sizes (like size 11), the band thickness, the radius of the ring itself, and the height of the band. I also want to be able to control the number of facets to make it smoother or more angular.

Additionally, I need to be able to optionally add a setting for a stone. The setting should be a rectangular box centered on the top of the ring and also allow parameters to control its width and length. The setting should be hollowed out, so that it appears to be attached to the top of the ring after it's placed rather than just a solid block sitting on top.

Here's a more detailed breakdown:

*   **Ring Band:**
    *   **Inner Diameter:** Based on a size parameter (like US ring sizes), use an equation to roughly calculate the inner diameter, accounting for a small tolerance adjustment: `intdiam = 0.8128 * size_NA + 11.63 * 1.03;`
    *   **Band Thickness:** Control the thickness of the ring band.
    *   **Band Radius:** Control the radius of the ring curvature (the torus radius).
    *   **Band Height:** Control the height of the band.
    *  **Band Facets:** Control the number of facets around the circle.
*   **Stone Setting:**
    *   **Width:** Control the width of the rectangular setting.
    *   **Length:** Control the length of the rectangular setting.
    *   **Position:** The setting should be centered on top of the ring band at the outer edge (relative to the x-axis in OpenSCAD).
    *   **Hollowed:** The setting should be hollowed out so it looks like a box attached to the band.

I'd like all of these values to be easily adjustable parameters at the top of the SCAD file. The basic ring band should always be created, and the setting should be controlled by a boolean parameter, `generate_setting`, that defaults to `false`.

I'm not using any external libraries in my current setup, and I'd like to keep it that way if possible. Can you please generate the SCAD files for me?

Hey, I'm looking to get a custom CFexpress card holder designed in OpenSCAD, and I want it to be parametric so I can adjust it later. I've seen a few designs out there, but none quite fit what I need, and I want to make sure I can easily customize it in the future. I have a fairly specific set of requirements:

1.  **Card Slots:** I need to be able to specify the number of card slots, anywhere from 1 to 50. The holder should be able to accommodate CFexpress Type B cards, and I need the option to orient the cards either horizontally or vertically.

2.  **Box & Lid:** I need a box with a corresponding lid. I'd like to be able to specify if I want just the box, just the lid, or both. If I request both, the lid should have a snug fit on the box. Also, the lid should have a lip or something to keep it from sliding around.

3.  **Card Dimensions & Tolerance:** The design needs to account for the actual dimensions of CFexpress Type B cards and have some tolerance built in. Specifically, when they're in a horizontal orientation the slot should be 38.5mm + tolerance in one dimension, and 29.8mm in the other, and 3.8mm + tolerance for depth. The vertical slot would be those dimensions swapped for x & y. I'd also like some space between the card slots. Let's say 6mm of spacing between slots.

4.  **Offsets:** I need to be able to adjust the offsets of the card slots from the edges of the box.

5. **Lid Fit:** There should be a small tolerance built in to the lid to ensure it fits easily. The lid also needs some method of securing itself, possibly a lip or inset.

6.  **Corner Rounding:** It would be great to have an option for corner rounding on the box and lid.

7.  **Preview:** If possible, I'd like to get a warning if I select to generate neither box nor lid to keep me from printing nothing.

I think I can handle the parameter adjustments myself, but I will need this to generate the box & lid in a way that makes sense for printing. The lid should be oriented such that it is printed in the optimal direction. The generated box should likewise be oriented for printing. It would be helpful if the code used some meaningful variable names to make it easier to understand.

Let me know if you need more information. Thanks!

Hi, I'm looking to design a customizable wire grommet and I'd like it to have a separate lid. I've been playing around with an existing design, but it's a bit clunky and I'd like to start fresh with something more parametric.

Essentially, I need a grommet that fits into a hole in a surface and a lid that snaps into the grommet. I need to be able to control a lot of the dimensions.

For the grommet itself, I need:

*   An outer diameter that I can specify.
*   The thickness of the top plate (the part that sits on the surface).
*   The wall thickness of the grommet itself.
*   The depth of the grommet – how far it extends below the surface.
*   A "brim" that overlaps the edge of the hole in the surface, so I can hide any rough edges from drilling. This brim should be on both the grommet and the lid, and I should be able to set the brim's size.

For the lid, I need:

*   The thickness of the lid's top plate.
*   How far the lid overlaps *into* the grommet.
*   The wall thickness of the lid, specifically the part that overlaps into the grommet.
*   A hole for cables to pass through with a settable diameter.
*   The position of the cable hole, either in the center or near the edge of the lid.
*   Optional text on the top of the lid.

I would like the OpenSCAD to use the "write.scad" library for the optional text, and "build_plate.scad" for displaying the design on a simulated printer bed. I do not have copies of these libraries to share. Also, could the code be set up to handle reasonable resolutions, say with `$fn = 120`?

It would also be helpful if the grommet and the lid were offset from each other, say 10mm, to keep them distinct.

Could you also make it so that I can select two preview tabs called "Text" and "Build Plate", which change the rendering between showing the text alone on a blank background and the full output on a build plate? If I choose another option besides Text or Build Plate, it should show all objects on a build plate, as well.

I think that covers everything. Let me know if you have any questions.

//   I added some more customizable items for the grommet:
//    New configurable items for the grommet:
//       + The size of the "brim" around the grommet.
//       + The depth of the "hole" for the grommet.
//       + The thickness of the grommets plate.
//       + The thickness of the grommets wall.
//    New onfigurable items for the lid:
//       + The thickness of the lid plate.
//       + The overlap of the lid into the grommet.
//       + The thickness of the lid walls.
//       + The diameter for the cable bushing.
//       + The location of the cable bushing.
//
//    Other things:
//       + Havy renamming involved to make the dependencies more clear for me!
//       + added colors to the different parts to make the debugging easier
//    Please note:
//       - This is NOT a multicolor design.
//       - Text on the plate requires "write.scad" placed in the "write"
//         subdirectory located below the "libraries" directory of SCAD.
//       - The display on a virtuell printer plate requires "build_plate.scad"
//         in the "utils" subdirectory located below the "libraries" directory
//         of SCAD.
//
//   Change Log:
//      v1.0  25.09.21 Created
//      v1.1  26.09.21 Grommet and lid wall thickness - set resolution to 1/10 mm
//                     Grommet and lid plate thickness - set resolution to 1/10 mm
//                     Changed default font size to 5
//                     Decreased the lid diameter by 0.2 instead of only 0.1
