Hey there! I'm looking to design a sewable button battery holder, and I'd love some help generating the OpenSCAD files. I'm imagining something similar to the button battery clips you see on Thingiverse, but with a few key differences and lots of parameters to play with.

Here's what I'm thinking:

*   **Battery Support:** It needs to support a few different button battery types, specifically CR2032 and AG13, but also allow for custom sizes where I can specify the radius and width of the battery.
*   **Sewable Design:** The key thing is that this holder needs to be sewable. So I'm envisioning small holes or loops at the edges of the design so I can sew it onto fabric. I want to specify a radius for the sew holes and if the top part should have them or not (true/false).
*   **Two-Part Design:** I'd like the design to be composed of two parts: a base part and a top part, which are designed to hold the battery between them, and the top part is a 'clip' that fits over the base. These two parts could be printed together as a single part, or as separate components which can then be assembled. I would like to be able to choose whether to generate top, bottom or together parts via a parameter.
*   **Edge Thickness**: I need a parameter to specify the thickness of the edges, and it should be linked to a factor of the nozzle diameter.
*   **Engraved Text:** It would be really cool to have the option to engrave text on the top part, so there's two lines of customizable text and the user can specify width and height for both.
*   **Racked Printing:** I'd like to be able to produce these in a rack/array using parameters for rack_x, rack_dist_x, rack_y and rack_dist_y.
*   **Build Plate:** It would be ideal to have the build plate visualized for sizing in the openSCAD preview, which is a nice visualization for ensuring it all fits, and should allow selection between a few common 3D printer build plates, and manual specification of the build plate size.

I'll be using these libraries:
*   MCAD
*  utils

The specific files I will use from the MCAD library are: fonts.scad

The specific files I will use from the utils library are: build_plate.scad

Let me know if I can clarify anything!

Hey, I'm looking to design a custom endstop striker for my 3D printer, specifically for optical endstops. I've seen some designs that use a bolt and nylock nut combo as the striker, but I want a version that's more customizable and robust. I also need to be able to tweak the striker shape more easily.

Basically, I need a part that has a cylindrical base with a hole for a bolt to pass through, and a counterbore or pocket for a nylock nut to be press-fit and possibly CA-glued into. Then, sticking out from the top, I want a thin, rectangular "striker" to block the optical sensor. I need the dimensions of all these features to be configurable via variables.

Could you generate an OpenSCAD file for this? I'd like to control these parameters:

*   **Main body:**
    *   Diameter
    *   Length
*   **Nut pocket:**
    *   Diameter (for the nylock)
    *   Depth (how deep the pocket is)
    *   Height (for nut height)
*   **Bolt hole:**
    *   Diameter
*  **Striker:**
    *   Length
    *   Width (x dimension)
    *   Height (y dimension)

I would also like to be able to control the overall position of the striker in the z dimension. It would be great if you could center the base of the cylinder on the origin, and then control how far up the striker extends by a simple `striker_z_offset` variable.

I think using the standard `cylinder()` and `cube()` primitives should be fine for this. No need for anything too fancy. I don't see any need to use any external libraries, but please make sure everything is well-parameterized. Let me know if you need any more information. Thanks!

I'm looking for an OpenSCAD design for a mount that I can use with a dial indicator on my 3D printer. It should clamp onto the X-axis gantry and provide a stable point to mount the dial indicator. I'd like it to be parametric, so I can adjust it if needed for different printers or dial indicators.

Specifically, the mount needs a clamp that goes around the gantry. The gantry thickness is about 9.65mm, but I'd like to have a variable clearance for the clamp so I can adjust for a good fit. Also, the clamp should have an adjustable lip that extends back, but not so far that it hits the V-rail on the X-axis. I need to specify the clamp length and wall thickness too.

The design also needs a shelf that extends out, with a hole in it to mount the dial indicator shaft. I need to be able to control the outer diameter of the dial indicator shaft, as well as the clearance around the shaft hole. Additionally, I need to be able to adjust how far the shaft hole edge is offset from the face of the gantry.

Could you create this for me? I would like to specify all these parameters, including:

*   `clamp_clearance`: How much extra space to give the clamp.
*   `lip_depth`: How far back the clamp lip extends.
*   `clamp_length`: Length of the clamp.
*   `wall_thickness`: Thickness of the clamp walls.
*   `shaft_od`: Outer diameter of the dial indicator shaft.
*   `shaft_clearance`: Extra space around the shaft hole.
*   `hole_border`: Offset of the hole edge from the gantry face.
*   `clamp_gap`: The thickness of the gantry (fixed, this is not meant to be a user parameter).

I need the whole design to be in a single file - no external files - so it can be self-contained. Also, I would like the design to *not* use any libraries. Thanks!

I'd like to create a heart-shaped chain, and I'd like it to be parametric so I can easily adjust things like the number of links and the thickness. I have a general idea, and I've even seen a design like this before, but I'd rather start fresh and have something well-parameterized.

Specifically, I want to be able to choose between creating a straight chain and a closed loop chain. I also need to be able to specify the number of links. The individual heart links need to have a thickness that can be set too, so I can make them more robust. It'd be nice if I could specify whether I want to print all the links at once, or if I want to output separate files for the even and odd links; the latter case would make it easier to do dual-extrusion printing with different colored links. The heart shape should be approximately as shown in the provided example. I'm not sure if you'll need that, but I've seen designs where the heart is based on a polygon, and that's what I'm expecting.

For the closed-loop option, I understand that you'll need to calculate a radius based on the number of links, which is fine. I just want to be able to specify the link count. Make sure that the final link connects back to the first link in a closed loop, and don't let the links interfere with each other. I would like the final model to be reasonably printable and robust without being too big or blocky.

I'm hoping that I can achieve this using standard OpenSCAD primitives and transformations; I'm not expecting that any specialized libraries are needed here. Can you help me with that? I need the main .scad file and any other necessary files.

Hey, I'm trying to design a folding cube with filament hinge pins, but I'd like to make it parametric from the ground up. I really like the design from emmett, but I want to be able to easily adjust the cube size, pin and hole dimensions, and the number of folding motions. Basically, I want to replace the existing cone and socket hinge with holes for pins and make sure it's super durable. I'm envisioning using 3mm filament for the pins, but I want to be able to specify the pin diameter and hole tolerance.

I need a few things:

*   A module for a single cube "bit" with pin holes on one edge, taking into account the required tolerance for smooth rotation. This will be a cube with a cylindrical hole going through one edge for the hinge pin, plus some support structure around it.
*   A module to generate the support structure around the pin holes. It's kinda like a little "ear" sticking out on either side of the pin hole to give it more strength.
*   A way to position and orient four of these "bits" to create a foldable cube. I would like to be able to rotate these "bits" around the hinge pin in a sequence to visualize the folding animation.
*   The ability to choose to generate just one bit, or a plate with all 4 bits for printing, or an animated assembly.
*   Parameters for:
    *   Cube size (L)
    *   Pin radius (R)
    *   Hole radius (H)
    *   Tolerance (tol)
    *   Number of folding motions (n)
    *   Angle of supports
    *   Fillet size on all corners of the cube bit.
    *   $fn for smooth circles.

I'm not worried about the snap-fit hinge, I just need the hole for the pins, and I want to control all of the dimensions. Can you create this for me in OpenSCAD? I'd like to be able to easily tweak the parameters and export the pieces for printing, as well as visualize the animation. I don't need any external libraries to do this. I'm just looking for the core mechanics for the model.

And as a follow up to my first query, I would also like to ask if you can incorporate a feature that lets me control the fillet radius of the cube. Basically, it would round the corners and edges of the cube bits and also apply this rounding to the supports, but not to the cylinders for the pins. Can you add that to the OpenSCAD code? I would want this to be an independent parameter.

I need an OpenSCAD design for a customizable filament guide for a 3D printer with a solid metal frame, specifically like the Prusa i3 Berlin. I'm using a loose spool mounted behind the frame, so the design needs to account for that.

The main parameters should be:

*   `frame_thickness`: The thickness of the printer's frame.
*   `guide_x`: The horizontal distance of the guide opening from the frame.
*   `guide_y`: The vertical distance of the guide opening from the frame.
*   `inner_diameter`: The diameter of the hole in the filament guide.
*   `side`:  A boolean or enumerated value that specifies if the spool is on the left or right of the frame.

There will also be some other advanced parameters that I will need to be able to adjust for the clamp/frame holder part of the design:

* `grip_depth`: The depth of the frame clamp.
* `grip_opening_height`: The height of the opening in the clamp for the frame.
* `grip_wall_thickness`: The wall thickness of the frame clamp.
and for the arm and guide part of the design:
* `filament_guide_depth`: The depth of the filament guide.
* `filament_guide_wall_width`: The wall thickness of the filament guide.
* `filament_guide_notch_width`: The width of the notch opening in the filament guide
*   `arm_width`: The width of the arm connecting the clamp to the guide.
*   `arm_depth`: The thickness of the arm connecting the clamp to the guide.

The guide should have a clamp that fits onto the frame, an arm extending from the clamp, and a circular guide at the end of the arm, with a notch opening to get the filament in. The arm's length and angle should be automatically calculated based on the `guide_x` and `guide_y` parameters. The design should be parametric, so all parameters are easily adjustable. I want to use the `build_plate` module from the `utils` library to show the print area for a printer with a build area of 200x200x200 mm. I do not need any .scad files other than the main one.

I'd like to create a parametric OpenSCAD design that takes a string of characters, interprets it as a 2D pixel art grid, and extrudes it into a 3D object. The input string would use `/` to represent line breaks, `*` to represent a pixel that should be rendered as a cube, and any other character would be ignored.

Specifically, I need the following parameters to be configurable:

*   **`pixels`**: The string that defines the art.
*   **`xUnit`**: The width of each pixel in mm.
*   **`yUnit`**: The height of each pixel in mm.
*  **`zUnit`**: The depth of each pixel in mm (extrusion height).
*   **`overlap`**: The percentage of overlap between pixels. A negative value means they will be gapped, zero means they will be touching, and positive means they will overlap.
*   **`center`**: A boolean that should determine whether to center the result on the origin.

I would like the code to include a `newPixel` module that takes in these parameters, including the `pixels` string, and draws the 3D shape using cubes.
I'd like to use the `split` function I provided to handle the string parsing and splitting, the `subString` function to parse the strings based on the split function output, and the `splitInfo` to help the split function. I also plan to use a cube module.

I'd like a parametric OpenSCAD design for a box holder, kind of like a clamp.  I need to be able to specify the dimensions of the box it's going to hold – height, width, and length – as well as the thickness of the material used for the holder itself.

The holder will have a base block that the bottom of the box rests on and a top tab that extends over the box. I’d like to be able to specify the height of that base block and the length of the top tab.  Also, there should be optional side tabs to extend out to the sides of the box which I also want to be able to configure.

The holder needs a screw tab for mounting. I'd like to specify the width of this mounting tab, the diameter of the screw, and the spacing between the screw holes in the mounting slot.  I need this to be a slot to allow some adjustability in the screw location.

Finally, the design should include chamfers on the screw tab. I need the clamp to be in two mirrored halves, meant to be mounted on a wall.

I'd like to be able to adjust all of these dimensions through parameters in the OpenSCAD file(s). I don't have a preference on whether this is a single file or multiple files, as long as it can be easily customized. I don’t have a preferred library to use. Thanks!

Hey, I'm trying to make a customizable movement tray for wargames. I've got a basic design figured out, but I need help making it parametric so I can easily adjust the size. I want to be able to control the overall width of the tray as it faces the enemy, the depth of the tray going away from the enemy, the height of the edge, and the width of that edge.

Basically, it's a rectangular tray with an edge that goes around it. The important thing is I'd like to be able to adjust these dimensions:

*   `tray_width`: The width of the tray facing the enemy.
*   `tray_depth`: The depth of the tray going away from the enemy.
*   `edge_height`: The height of the edge around the tray.
*   `edge_width`: The width of that edge.

I'd like the tray to be centered, and the inside of the tray to be inset to make the edge. I'd prefer if the OpenSCAD file has clearly named parameters and is easy to customize. It would also be helpful if the code included comments. Could you create an OpenSCAD file for me with these parameters?

[Assistant]
MovementTray.scad:

// Depth of the tray away from the enemy?

// Edge height of tray?
edge_height = 3;  // [2:5]
// How wide is the edge?
edge_width = 2; // [1:5]

difference () {

    cube ( [tray_width, tray_depth, edge_height], center=true ) ;

    translate ([0,edge_width,1]) {
        cube ( [tray_width-edge_width*2, tray_depth-edge_width+1, edge_height], center=true ) ;
    }

I'd like to create a cookie cutter design, and I need an OpenSCAD file to generate it. The cookie cutter will have an outer cutting edge and, optionally, an inner cutting edge. There will also be a frame/grip at the top.

Here are the details:

*   **Outer Cutter:** This is a basic square shape.
    *   The outer side length will be a parameter called `Outer_Side`.
    *   The outer height will be a parameter called `Outer_Height`.
    *   The thickness of the outer cutting edge will be a parameter called `Cutter_Thickness`.
*   **Inner Cutter (Optional):** This is another square shape, smaller than the outer cutter, which sits inside it, also creating a cutting edge.
    *   The difference in side length from the outer cutter will be a parameter `Inner_Side_Difference`.
    *  The difference in height from the outer cutter will be a parameter `Inner_Height_Difference`.
    *   The thickness of the inner cutting edge will also use `Cutter_Thickness`.
    *   There should be a boolean parameter `Has_Inner_Cutter` to enable/disable this feature.
*   **Frame/Grip:** This provides a handle for the cookie cutter.
    *   The thickness of this frame should be a parameter `Frame_Thickness`.
    *   The frame should extend beyond the outer cutter's bounds by a parameter `Frame_Flange`.
    *   The frame should be centered on the cookie cutter, but raised slightly from the bottom, using a value of 1/10th of `Frame_Thickness` to raise it above the plane.

I need all the dimensions in millimeters.

Please provide an OpenSCAD file (or files if that makes sense) that implements this design. Please do not use any external libraries.

I'm looking for a design for a wall-mountable cable holder that I can customize. I need an OpenSCAD file (or files, if it makes sense to break it down). The basic idea is a flat back that mounts to the wall, and then a holder part that sticks out at an angle, with slots cut into it for cables.

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

*   **Material Thickness:** I need to specify the thickness of the material (e.g., 3mm for MDF). This is important for joins and laser cutting.
*   **Kerf:**  I need a kerf parameter for adjusting the fit of parts that slot together.
*   **Slot Width:** I need to specify the width of each slot, to match the cable width and keep them from easily falling through the holder.
*   **Number of Slots:**  I need to specify how many cable slots there should be in the holder.
*   **Angle:** The angle between the back and the holder needs to be adjustable.
*   **Overall Width:** The total width of the cable holder should be adjustable.
*   **Back Height:** I need to set the height of the wall-mounted back piece.
*   **Holder Height:** I also need to control how deep the cable holder is.
*   **Slot Length:** I need to control how deep the slots are.
*   **Holder Beneath:** I need to specify the amount of material underneath the holder on the sides. This affects the radius of those end pieces too.
*  **Holder Offset:** the distance between the holder and the back, measured along the holder.

It would be useful if the code automatically calculated the tine widths (the bit of the holder between slots) and the slot spacing based on the other values and the overall width. I'm thinking the tines should all be the same width, except the first and last, which should be a single thickness.

I'd also like it if the slots were a "rounded rectangle" shape, or something similar, not just straight cuts.

Finally, the side pieces should be automatically created. They need to have notches cut into them to hold the back and holder sections. Also, the side pieces should have a rounded edge. It's a Minkowski sum of a polygon and a circle for that.

I don't need to add any libraries specifically, but I may in the future, so please ensure your code can be expanded upon!

Hey, I'm trying to design a custom tapered roller bearing generator in OpenSCAD. I've got some basic ideas laid out, but could use some help building it out into a parametric, modular design.

Here's what I'm aiming for:

**Core Functionality:**
*   **Parametric Dimensions:** The generator should allow the user to specify the outer diameter (OD), inner diameter (ID), and width of the bearing.
*   **Tapered Rollers:** It needs to create tapered roller bearings, which means the rollers themselves will be frustums rather than cylinders. I'm imagining a way to define the taper angle or the difference in radius at each end of the roller.
*  **Roller Count**: I'd like to be able to specify the number of rollers rather than relying on a calculation.
*   **Clearance:** The design should include a clearance gap between the rollers and the inner/outer races. This clearance should be a parameter that I can control.
*   **Optional Section:** An optional cutting plane is needed, allowing users to inspect a cross-section of the bearing.

**Modular Design:**
*   The design should be broken into modules for each component (inner race, outer race, rollers).
*   I want to have a "createBearing" module that combines all the components into a complete bearing.
*  The code should allow for simple modifications for roller and race profiles, potentially by passing parameters.

**Other Requirements:**
*  I'd like to use the BOSL2 library if it's applicable. I think it could help with some of the geometric calculations and potentially for rendering.
*   I want to be able to choose the resolution with which the bearing is generated using a variable.

Basically, I'd like the flexibility to generate a variety of tapered roller bearings with different sizes and configurations. I'm hoping to get an OpenSCAD file (or multiple files if that makes sense) that I can easily adjust and use for my projects. Let me know if you need any clarification!

Hey, I'm looking to generate some OpenSCAD files for customizable picture frames. I have a basic idea of what I want, but I need your help fleshing it out into a fully parametric design.

Essentially, I want to be able to specify the dimensions of the picture or sign I want to frame, and have OpenSCAD generate the frame pieces. The key is that the design needs to be easily printable, even on smaller beds, which means it will need to be broken down into parts that can be assembled. I'm imagining something like the design in the existing file `PictureFramev2.scad` that I attached, but I want to completely re-implement this from scratch as a parametric model.

Here's what I'm thinking:

**Core Functionality:**

1.  **Parametric Dimensions:** I need parameters for:
    *   Picture Width (in mm or inches, user selectable).
    *   Picture Height (in mm or inches, user selectable).
    *   Picture Thickness (in mm or inches, user selectable).
    *   Frame Thickness (the thickness of the frame material itself).
    *   Arm Width (the width of the frame arms holding the picture).
    *   A spacing parameter (to allow for some variance between parts).
2.  **Modular Design:**
    *   **Center Piece:** A central part that connects the frame arms. I want this to have an option to include screw holes, or to have it use a key and slot type connection. I'd like to be able to choose a center connection type from a list.
    *   **Frame Arms:**  The individual arms that hold the picture in place. I need to be able to make them in mirror image pairs.
    *   **Assembly:** It should generate a complete assembled frame by placing multiple frame arms at specified angles. This includes calculating the right angles and positions for the arms to join with the center piece.
3.  **Adjustable tolerances:** A gap parameter should adjust for printing variance.
4.  **Export Options:** I'd like options to:
    *   Preview the assembled frame.
    *   Generate individual STLs for the center piece and the arms.
    *   Generate a plate layout of the pieces, ready for printing in one job.

I'd really like for you to start fresh and not try to modify the code I gave you.  The way it is structured doesn't work with my current design goals.

I'm comfortable using basic OpenSCAD primitives like `cube`, `cylinder`, `translate`, `rotate`, `difference`, `intersection`, and `mirror`.  I don't need any external libraries.  Let's start with the basics.

Hi, I'm looking to design a mount for an old Apple iSight camera that will attach to a specific 3D printer. I've seen examples of mounts using a similar clamping approach, so I'm hoping to do that in a parametric way, but I'm finding it tricky. Here's what I'm trying to accomplish:

The basic idea is that the mount will have a base that clamps onto a rail (like a standard 2020 extrusion, but it's actually a slightly different rail on a MakerGear M2 printer) and then have a mounting block that the iSight will attach to. The camera's mount is a pair of holes on an oval axis. The iSight's form is essentially a cylinder with a specific radius.

I'd like the design to have the following adjustable parameters:

*   `extrusion_width`: The width of the 3D printer's extrusion bead. This determines how thick the walls should be.
*   `wall_width`: The thickness of the walls used in the construction of the mount, defined as a multiple of `extrusion_width`.
*   `base_height`: The height of the clamping base.
*   `mount_hole_major_axis`: The long axis of the oval on the iSight camera base.
*   `mount_hole_minor_axis`: The short axis of the oval on the iSight camera base.
*   `mount_block_height`: The total height of the mounting block above the base.
*   `clearance`: A small clearance value to ensure parts fit together.
*   `y_offset`: The distance from the front face of the gantry rail to the leading edge of the iSight camera body, assuming we clamp to the front side of the rail.
*   `x_offset`: The distance from the side face of the rail to the center of the camera mount.
*   `isight_radius`: The radius of the iSight cylinder.

I envision the design consisting of a few main parts:

1.  **Clamping Base:** A flat base that clamps onto the rail. This part should have the x and y offsets to position the mount properly.
2.  **Mounting Block:** A block extending upward from the base with the hole for the camera mount. The mounting block will house the mounting hole. The height will be controlled by `mount_block_height`.
3.  **Mounting Hole:** An oval-shaped hole through the mounting block, which will interface with the iSight mount. It needs to have clearance.

I'm hoping to have the whole thing parametric, and generate the full mount and a separate test mount with a hole that allows me to verify the dimensions of the iSight mount. Also, it would be helpful if the code could include a preview of the mount so I can verify its dimensions against my printer.

The OpenSCAD code should use the `hull()` function to define the oval shapes for the mount and the holes. I think I'd like to avoid custom libraries, as this is fairly straightforward.

Can you generate the necessary OpenSCAD files for me?

I need to design a holder for a bike light, specifically the male part that attaches to the bike, and I want to make it customizable so I can adjust the dimensions to fit different lights. I've got some measurements here that are important, and I'm looking for a design that I can modify and attach to a bike mount.

Here are the key dimensions:

*   **Wall Thickness:** I want to control the minimum thickness of the plastic walls, and I need it to be adjustable. Let's start with 2mm.
*   **Inner Width:** This is the side-to-side width of the male part of the light, measured at 17.21mm.
*   **Inner Depth:** This is the depth of the male part, measuring 3.6mm.
*   **Part Height:** The overall height of the part that holds the light, which can be set to 22.75mm for now. It mainly needs to be long enough to reach the latch mechanism on the light.
*   **Handle Width:** The width of the thumb part on the latch, which is 11.6mm.

I need a few specific design elements:

1.  **Main Body:** The core structure of the holder should have a cavity sized to fit the male light part.
2.  **Latch:** I need to include a working latch mechanism, mimicking the one found on a Planet Bike light mount. This includes a small bottom latching block, its base, and the thumb handle to move it.
3.  **Cuts for Latch Movement:**  There should be cuts in the side of the main body that allow the latch to move back and forth.
4.  **Mirroring:** The main body of the part needs to be mirrored so the whole thing fits together properly.
5.  **Customizable:** All of these key dimensions need to be easily customizable using variables at the top of the file.

The part should be anchored at (0,0,0) to make it easy to add other mounts or structures later. I also need the handle of the latch to be modeled in a way that allows for some movement or "flex".

I'm looking for a full parametric OpenSCAD model with all of these features. Can you generate that for me? I'd like the model to avoid coincident faces to prevent issues when rendering.

I'd like a parametric OpenSCAD design for a card box that can hold a variable number of standard-sized playing cards. The box should have a base and a lid, with the lid able to open out flat to act as a second container. Think of it as a box that can hold a draw pile in the base and a discard pile in the lid when it's open.

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

*   **Card Height:**  This should be adjustable in millimeters. I'm thinking a range from 50 to 150mm should be good.
*   **Card Width:** This should also be adjustable in millimeters, with a range of 30 to 100mm.
*   **Number of Cards:** An integer value representing how many cards the box should be able to hold. The range should be from 10 to 200 cards.
*   **Sleeve Type:** This should be a dropdown with three options: "none", "light", and "premium".  These represent the different thicknesses of card sleeves I might use. When set to "none", the card thickness should be assumed as 0.3mm per card. When set to "light", assume 0.5mm thickness per card and add 2mm to both card height and width. For "premium", assume 0.6mm card thickness per card, and similarly add 2mm to both height and width. These are just approximations, so if the actual cards are slightly different, I will adjust the number of cards parameter appropriately.

The box design should have a small lip to help the lid stay in place when closed. The two halves should connect via a simple cylinder hinge on each side. It doesn't need to be anything super fancy. Also, make sure the lid can open and sit flush when rotated out so that both the lid and the base can hold cards. I'm not sure if this requires a "stop" in the hinge to keep it from rotating past 180 or if simply designing it correctly will manage that.

I'm not picky about aesthetic flourishes, I'm going for functional. I'm thinking there should be a small clearance of a few mm between the walls of the box and the cards, and I'd like the corners rounded. Perhaps a small bevel on the edges of the box parts would be good as well.

Could you generate the OpenSCAD file(s) for me? I don't have any specific libraries I require, so just what you find most appropriate.

I'm looking to create some movement trays for tabletop miniatures, and I'd like to use OpenSCAD to make them parametric. I've already made a simple one, but it's a bit clunky, and I think it can be improved upon. I'd like to be able to easily adjust several key things:

First, the base size needs to be adjustable. I’d like options for common sizes, so it should have a dropdown that allows you to choose from sizes like 20mm, 25mm, 28mm, 40mm, 50mm, and 54mm.

Second, I need to be able to choose how many miniatures wide and deep the tray will be. So, there should be two separate dropdowns (or number input fields), one for the width and one for the depth, so you can specify how many figures will fit across and back.

Third, I'd like to be able to control the width of the edge of the tray and its height. These should be separate parameters, so I can make the edge thicker and higher if I want more support for the tray.

Finally, I'd like to have the code add little alignment markers in the base of the tray to show me where to place the miniatures. I used a small cube in the last one, but maybe there's something that looks a bit nicer? They don't need to be visible from the outside of the tray, just a small indented mark on the inside.

I think that's about it. I don't need anything complicated, just a straightforward movement tray generator with the parameters I've mentioned. Oh, and I think the units should be in mm for consistency. Do you think you could do that? I don't have any libraries I need to include other than the basic OpenSCAD functionality.

Hi, I'm looking to design a corner piece for constructing cubic frames, primarily for educational purposes. We'll be using these with broken arrow shafts to create 1 cubic foot frames for studying ecosystems, so they need to be robust and easily customizable.

I envision a corner piece that has three cylindrical openings, each intersecting at a 90-degree angle with the others, to accept the arrow shafts. It also needs to have a solid cube base so that it sits flush on a surface.

Here are my specific requirements:

*   **Cylindrical Openings:**
    *   The radius of each cylindrical opening should be a variable, let's call it `cyl_rsize`. I need to be able to adjust this between 1mm and 20mm to accommodate different shaft diameters.
    *   These openings should be centered on the edges of the cube and run the length of the intersection of the faces.
    *   The length of these cylinders should be greater than the cube dimensions, so that they can run past the edges.
*   **Wall Thickness:**
    *   The thickness of the material surrounding the cylindrical openings, or the "wall padding" needs to be adjustable. Let's call this variable `wallThickness`. I'd like to be able to vary this from 1mm to 20mm.
*   **Base Cube:**
    *   The main body of the corner should be a solid cube, with the dimensions determined by the cylindrical radius and wall thickness.
    *   The center of the cube should sit flush with the center of the cylinder intersections. This is the solid part of the design that is not cut away for the cylindrical holes.
*   **Base Disc:**
    *   We also need a thin disk at the bottom of the design to help with bed adhesion when printing. This disk should be slightly larger than the cube and offset slightly down, so that it does not interfere with the base of the cube.
*   **Parametric Design:**
    *   It's vital that the entire design is parametric. I need to be able to change `cyl_rsize` and `wallThickness` and have all parts of the design adjust accordingly.

For libraries, I think we'll just need the basic OpenSCAD functions, I don't think we need anything from an external library like BOSL or MCAD.

Could you generate the OpenSCAD code for this? Thanks!

I'm looking to create a customizable set of knitting needles, and I'd like to use OpenSCAD to make the design parametric. I've seen a few designs online, but I want one that I can tweak to get the exact dimensions and style I need.

Here's what I'm hoping for:

**Needle Types:** I need to be able to create three different types of needles:

*   **Straight Needles:** These are the standard type with a pointed tip at one end and a blunt butt on the other.
*   **Double Pointed Needles (DPNs):** These should have a point at *both* ends.
*   **Circular Needles:** These are similar to the straight needles, but the blunt end should have a hole through it for inserting a flexible wire or cord so that I can create actual circular knitting needles.

**Parameters:** I need these aspects of the design to be controllable via parameters:

*   **Length:** The overall length of the needle (tip + shaft).
*   **Diameter:** The diameter of the needle shaft.
*   **Tip Angle:** The angle of the cone forming the needle tip.
*   **Tip Sharpness:** How blunt or sharp the tip is, which should be controlled by the radius of a sphere that creates the rounded point.
*   **Number of Needles:** How many needles to generate.
*   **Wire Width (for Circular Needles):** The diameter of the hole for the wire in the circular needle design.
*   **Slice Option:** A boolean to slice the needles in half lengthwise so they're easier to print, mainly for FDM/FFF printers, defaulting to false.

**General Design:**

*   The needle body will be a simple cylinder.
*   The tip will be a cone shape, then smoothly rounded using a portion of a sphere.
*   The blunt end of the straight needle should be a short cylinder.
*   The blunt end of the circular needle should have a bore through it for the cable.
*   For sliced designs, the sliced edge should be flat.

I'd like the code to be well-structured and easy to modify. Can you help me generate OpenSCAD code for this? I'd like it if the code used the built-in OpenSCAD functions, but if you find the need to use libraries, BOSL2 would be preferred.

I'm trying to make a customizable cube, and I'm a little confused about how to make it work with the customizer. I started with a simple file (attached) but I realized it's not really doing what I want. I'm not sure how to expose the dimensions and offsets to the customizer so I can change them easily.

Essentially, I want to be able to modify the cube's length, width, and height, and its position (x, y, and z offset) all through the customizer interface. So, I'd be able to adjust these values without having to edit the code directly. Could you help me set up a parametric OpenSCAD file that does this? I think that means I need to use variables. I’m also planning to use this as a building block for other things, so it would be helpful if the module is separate from the main body.

I'm looking to create a customizable collet holder, specifically for ER-series collets. I'd like to be able to choose which collet size I want to accommodate (ER8, ER11, ER16, ER20, ER25, ER32, ER40, and ER50), and the design should automatically adjust for the different dimensions of each collet type.

The holder will consist of two parts, a bottom section and a top section. I want the option to generate either just the bottom, just the top, or both parts together. The bottom part will have cutouts to hold the collets, and the top will fit over it, kind of like a lid.

I'd also like to customize the overall size of the holder. I need to specify the number of rows and columns for the collets. For example, I might want a 5x3 arrangement of collets.  Additionally, I need control over the wall thickness of the box. There should be a bit of space between each collet, which should be based off the diameter of the collet itself.

Could you generate an OpenSCAD file or files to do this? I'm not picky about particular libraries, but I would like you to make it work with some standard library if possible.

[User]
Okay, so I'm looking to design a food forming stamp, kind of like the ones I've seen online, they are for making things like cookies or small patties. I've got a basic idea from this code I wrote, but I want to make it more flexible and parametric, and I'd like it broken into a few modules to make it easier to adjust different parts later. I also want to use one of those nice libraries, maybe BOSL2? I'm open to suggestions if it's a better fit.

Here's what I'm thinking:

**Core Stamp (the "weller" part):**

*   **Main Body:** This should be a cylinder with a given radius and height. I want to control the radius (`mainRadius`) and the wall height (`wallSize`).
*   **Holes:** There needs to be a series of small holes around the circumference of the main body. These will allow excess liquids to escape when pressing the food.
    *   There should be 6 holes equally spaced around the cylinder, maybe with a rotate step of 60 degrees?
    *   The holes should alternate between two radial distances from the center, one at 60% of the radius, the other at 70%, but never lower than 13.5mm, using `max(radius*multiplier, 13.5)`.
    *   Each hole should also be a small cylinder with a diameter controlled by `holeRadius` and should go all the way through the wall. It might be a good idea to add a little extra height to make sure they cut all the way through the wall, or we can do it with translate.
*   **Shaft:** This connects the main body to the handle, also a series of cylinders that get smaller towards the handle. I need a height parameter for that (`shaftHeight`), and it should have some stepped cylinder profile that goes from 12mm down to 5mm at the top and bottom with smaller transition cylinders in between.
*   **Handle:** A cylinder attached to the shaft, with a spherical cap. I need a height parameter for the cylinder (`handleHeight`).

**Cutter:**

*   The cutter is like a negative version of the stamp, designed to cut out the food before stamping.
*   It needs to be a hollow cylinder with an outer diameter larger than the stamp and an inner diameter a bit smaller than the stamp.
*   I need parameters for the cutter wall thickness (`cutterWallSize`), the gap between the cutter and the stamp (`gap`), and the overall height of the cutter (`cutterHeight`).

**Parameters (and defaults):**

*   `mainRadius = 25`
*   `wallSize = 4`
*   `holeRadius = 1.5`
*   `cutterWallSize = 0.75 * wallSize`
*    `cutterHeight = 35`
*   `gap = 0.5`
*   `shaftHeight = 16`
*   `handleHeight = 50`

**General Requirements:**

*   I want it to be easy to modify the number of holes.
*   The design should be parametric so I can easily change all those dimensions.
*   It should use BOSL2 if it's the best fit for something like this.

Could you generate the OpenSCAD code for these parts? I really want the BOSL2 library's module style, I'm sure that will make it easier to adjust things later. Let me know if you have any questions!
