I'd like to create a design for stackable, magnetic bowls for game pieces. I'm envisioning a hexagonal bowl with a lip for stacking and a magnetic insert. I'd like it to be fully parametric so I can easily change the size, depth, and other dimensions.

Here are the key features and parameters I have in mind:

*   **Shape:** The base should be a hexagon.
*   **Bowl Depth:** I want to control the inside depth of the bowl.
*   **Hexagon Width:** I want to control the width of the hexagon, defined by the short diagonal.
*   **Wall Thickness:** I want to specify the thickness of the bowl's walls, which will also affect the internal diameter of the bowl.
*   **Bottom Thickness:** I'd like to have control over the extra thickness of the bottom of the bowl in addition to the lip.
*   **Lip:** There should be a lip around the top edge for stacking. I want to be able to control its width and depth.
*   **Lip Spacing:** I need a parameter to control how much space there is between bowls when they are stacked, so I can make it a tighter or looser fit.
*   **Corner Radius:** The bottom of the bowl should have a curved shape with a configurable radius.
*   **Magnet Holes:** Each of the six sides of the hexagon should have a hole to insert magnets. I need to be able to set the diameter and depth of these holes. The holes should be a little larger than the magnets to allow for easy insertion.

I'd prefer that everything is measured in millimeters. I'd like to be able to specify all of these parameters in the scad file.

It would also be great if the file could use the `minkowski()` function and also generate a hexagon primitive that's defined by the short diagonal, instead of the normal circumradius.

Do you think you can handle this?

I'd like a parametric OpenSCAD design for a divided box. I need to be able to control the overall X, Y, and Z dimensions of the box, the number of rows and columns of internal dividers, and the wall and base thicknesses. It should also have optional bevels on the top edges along the X and Y axes, with adjustable bevel sizes. I want to be able to turn the base and each set of bevels on or off. I need the base to be created if requested and the bevels to only be cut when activated.

I'm envisioning a main `organiser_box.scad` file that defines the core box structure and includes the parameter definitions, and another `bevels.scad` for just the bevel creation so it's kept separate and tidy. It should probably use `difference()` to remove the bevels.

Please make sure the parameters are clearly named, like `size_x`, `size_y`, `height`, `num_rows`, `num_columns`, `wall_thickness`, `base_thickness`, `bevel_size_x`, `bevel_size_y`, `Base`, `Bevel_X`, and `Bevel_Y`. I need to be able to control all of those. Let me know if you need anything else from me!

Also, I'm not expecting anything fancy in terms of libraries, I'm just after the standard OpenSCAD operations.

I need to design a parametric shaft collar, something similar to the one I found online but I want to use libraries to help make the code cleaner and more robust.

Here are the key features I'm looking for:

*   **Shaft Diameter:** This needs to be fully customizable, representing the inner diameter of the collar where the shaft goes through.

*   **Outer Diameter:** The overall outer diameter of the collar should also be customizable.

*   **Gap Width:** The width of the split in the collar should be adjustable. This is where the collar clamps down.

*   **Thickness:** The height or thickness of the collar should be configurable.

*   **Screw Hole:** There should be a through-hole for a screw, with customizable diameter.

*   **Counterbore:** The screw hole should have a counterbore, with customizable diameter and depth.

*   **Nut Pocket:** I'd like to have a hexagonal pocket on the opposite side of the screw, also customizable, to hold a nut. This should allow for setting its rotation around the screw hole, as well. It should include customizable pocket width.

I would really like the design to be fully parametric, so I can easily change these values. I also really like being able to configure how smooth circular parts are using `$fn`.

I would prefer the final design to use the BOSL2 library, but if that's not feasible then another good library like MCAD would work as well. I would prefer not to have to define polygon code from scratch, if that's possible.

Could you generate the necessary OpenSCAD files for this?

I'm looking for an OpenSCAD design for a customizable fletching jig. I want to be able to adjust it for different arrow diameters and vane sizes. The jig should have a base, arms that clamp the vanes to the arrow, and an optional lid to hold everything together during the gluing process. It needs to be parametric so I can easily change the dimensions and other features.

Here are some specifics:

*   **Base:**
    *   I want to choose between a polygon or star shape for the base outline.
    *   The base needs a hole for the arrow, and the diameter should be adjustable. The hole can have a different diameter if I am using nocks that are larger than the arrow shaft itself.
    *   There should be cutouts for hinges that will connect to the arms. The depth and width of these cutouts should be customizable.

*   **Arms:**
    *   The arms need to attach to the hinges on the base and swing down to clamp the vanes.
    *   The joint between the arm and base should be either a ball joint or a pin joint (like a bolt or piece of filament).
    *   The arms need a gap for the vane foot, so that the tension is distributed evenly on the vanes and the glue can be applied.
    *   The arms should be adjustable in height so I can adjust the vane offset from the end of the arrow.
    *   The arms should have a cutout to accommodate the arrow.
    *   I need to be able to choose whether the vanes are straight or helical. If helical, the jig should apply the appropriate twist.
    *   The number of vanes (3 or 4, maybe 2 or 5) should be customizable.
    *   The length, width, and offset of the vanes should also be customizable, including the amount of turn if the vanes are straight.

*   **Lid:**
    *   The lid needs to fit over the base and arms.
    *   I also want the lid's shape to be either a polygon or star shape, independent of the base shape.
    *   It should have some lip to help hold it in place.

*   **Nock Alignment:**
    *   I want an optional alignment guide for the nock of the arrow, which can be disabled if I don't want it.
    *   I need to be able to set the width and height of the nock guide.
    *   For an even number of vanes, the guide should either align with an index vane, or in between the vanes for optimal clearance.

*   **Rendering:**
    *   The user should be able to choose the quality of rounded parts, using the `$fn` variable, ranging from 10 to 100, with a default of 30.
    *   The user should be able to select to display only the base, the arm, the lid, or all three together, to simplify printing.

I think that covers everything. The design should be parametric, so every dimension listed can be changed.

I'd like you to use the MCAD library for any useful modules it has.

Hey, I'm looking to create a customizable box with compartments and an optional insert, and I've seen a design that looks really promising! It's called "Box MkII" and it has some really cool features, especially the custom divider layouts and the option to add corner supports for the insert.  I'd like to be able to create a new design based on these concepts. I'll need it to be parametric so I can easily adjust the size, number of compartments, and all those things that the original design offers.

Here's what I need in terms of functionality:

*   **Basic Box Structure:**
    *   I need to specify the overall width (x), depth (y), and height (z) of the main box.
    *   The outer edge thickness (edge) should be adjustable, and the lip width (lipw) should be derived from the edge, likely as half of it.
    *   It needs to support a lid with a lip that fits inside the box, and I should be able to adjust the lip height (liph) and any additional internal height above the lip (lidaddheight)
    *   I'll also need to define a tolerance for the lip fit (tol) which should be split evenly between the lid and the box (piecetol) to create a proper clearance.

*   **Compartments:**
    *   I need to be able to define the number of compartments in both x and y directions (comp_x and comp_y).
    *   The height of these compartments should be a percentage of the internal box height (comp_perc).
    *   I should also be able to specify the border width for the compartment dividers (comp_border).
    *   Crucially, I need to include the option to add corner supports for inserts when the main dividers aren't being used (insertsupports).

*   **Insert:**
    *   The insert should have its own number of x and y compartments (insert_comp_x and insert_comp_y).
    *   Its height should be a percentage of the internal box height (insert_perc).
    *   I need to control the border width (insert_border) and the divider width (insert_divider) separately.
     *  There needs to be a clearance tolerance for how the insert fits inside the main box (insert_tolerance).

*   **Custom Divider Layouts:**
    *   This is a really important feature - I need to be able to define custom layouts for both the box and the insert dividers. These layouts are defined using vectors (`customboxx`, `customboxy`, `custominsertx`, `custominserty`) where a '1' indicates the presence of a divider section. The AI should understand how these vectors map to the dividers. I want to control what sections of each divider appear, rather than just removing entire dividers. I'd like the default to be `[1]` which indicates a continuous divider.

*   **General:**
    *   There needs to be an `epsilon` value, like in the original, for clean rendering in OpenSCAD, and I want to make sure that all internal dimensions are properly calculated.

I’d like the design to have the following modules, and to have the ability to output them individually or all at once:
*   `box()`: Generates just the box.
*   `lid()`: Generates just the lid.
*   `insert()`: Generates just the insert.
* `print_part()`: This will determine which parts get output depending on a `part` variable.

I think that's everything.  It would be great if you could provide the OpenSCAD code, I'm assuming I won't need to include any special libraries here, but let me know if you think otherwise! Let me know if you need more info! Thanks!

[User]
Okay, I'm looking to create a customizable organizer for Dupont cables, and I'd like it to be designed in OpenSCAD. I want to be able to adjust the length of the cables, the number of cables it holds, and have the option to split the bridge section into multiple segments for easier printing, especially since I'm using a smaller printer. I'd like to use the MCAD library for units.

The basic design should consist of three main parts: a "comb" section with teeth to hold the cables, a "bridge" section to span between the comb sections, and a "plate" which puts everything together. The user should have the option to render only the comb, only the bridge, or the complete plate for printing.

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

**General/Common Parameters:**

*   `part`: A string to choose which part to render – "comb", "bridge", or "plate".
*   `bridgeSegment`: An integer to select which bridge segment to render (or -1 for all). It should start from 0.
*   `cableLength`:  The total length of the cables to be organized (excluding connectors).
*   `numCables`: The number of cables the organizer will hold.
*   `numBridgeSegments`: The number of segments the bridge should be split into.
*   `itemSpacing`: Space between different components of the organizer when arranged into the build plate.

**Comb Parameters:**

*   `combThickness`: Thickness of the comb base.
*   `combBaseWidth`: The width of the comb base and the thickness of the bridge part.
*   `combToothLength`: The length of each tooth on the comb.
*  `combToothWidth`: The width of each tooth.
*   `combSharpLength`: The length of the pointy top on the tooth.
*   `toothBumpLength`: The length of the small bump feature on the side of each tooth.
*   `toothBumpThickness`: The thickness of the bump feature.
*   `combToothSpacing`: The space between the teeth.

**Bridge Parameters:**

*   `bridgeWidth`: The width of the bridge segment.
*   `bridgeHoleMargin`: Margin between the outer bridge border and any center holes.

**Joining Parameters:**

*   `joinSubtractLength`: Length to subtract from the total bridge length per join to compensate for imperfect fits of the pegs and holes between bridge segments.
*   `joinHoleWidth`: Width of the hole where the bridge segments and comb join.
*   `joinHoleLength`: Length (depth) of the joining hole.
*   `joinCombPegWidth`: Width of the peg on the comb that joins with the bridge.
*   `joinBridgePegWidth`: Width of the peg on the bridge.
*   `joinPegLength`: Length of the peg.

**Internal Parameters (These can be calculated internally):**

*   `combLength`: The overall length of the comb (calculated).
*   `combSpacing`: The distance between comb parts on the build plate (calculated).
*   `bridgeLength`: Length of a single bridge segment (calculated).
*  `bridgeSpacing`: The distance between bridge parts on the build plate (calculated).

The comb should have a main base and teeth extending from it. Some teeth should have small bumps on both sides, and the end teeth should have a bump on one side only. The teeth should be created using the `polygon()` command with linear extrusion. The bridge will have a hollowed center, and will have peg and hole shapes on the sides to allow joining to the comb and to other bridge pieces. The joins should have a small margin added to the hole size to ensure a snug fit.

I'm hoping you can generate the necessary OpenSCAD code. Let me know if you need any clarification.

I'd like to design a traffic cone, specifically one that's stable and hard to tip over, designed for 3D printing. I have an existing OpenSCAD file that gives a good idea of what I'm aiming for, but I need a version that's more customizable and easier to work with.

Here's a breakdown of the key features and how I envision them being adjustable:

*   **Overall Dimensions:**
    *   **Height:** I need to be able to set the total height of the cone. The existing code has a 'height' parameter, and that should be adjustable.
    *   **Base Diameter (Cone):** The diameter of the cone at its base, where it transitions to the base, should be adjustable. I have 'd_cb' in my existing file for that.
    *   **Top Diameter (Cone):** The diameter of the top of the cone, currently 'd_ct', needs to be a parameter.
    *   **Base Width:** The overall width of the base, including those rounded corners, should be configurable ('w_b').
    *   **Base Height:** The height of the base itself should also be a changeable parameter ('h_b').

*   **Stability and Weight Distribution:**
    *   The design should be weighted towards the base for stability. The code I have now accomplishes this by making the cone's walls thin.
    * I'd like for the core to be hollow, not solid.
    * I would like for the overall wall thickness of the cone to be a configurable parameter - 'w' in the provided code.

*   **Construction:**
    *   The base should have rounded corners, smoothly connecting to the main cone. The provided code uses a `hull()` with four circles to do this, which works great.
    *   The cone should be hollow, with a defined wall thickness, and connected to the base.
    * The code uses linear extrusion for the base; that works fine.

*   **Customization and Usage:**
    *   I'd like the option to render the cone in either 'preview' or 'render' mode, with different `$fs` and `$fa` values depending on the selected mode. It would be nice if you could reuse the functions in my code for that.

I don't want to use any external libraries, just basic OpenSCAD. I would prefer that the code be fully parametric, meaning that I should be able to easily change any parameter and re-render the design. The code needs to be well commented so that I can understand how it works and modify if I need to. Please keep the structure of the code logical and readable, similar to the way my example file is organized.

Essentially, I need a more flexible version of my existing cone.

Okay, I need a parametric hose coupler, and I've got some pretty specific needs. I'm working with flexible tubing, and I need to be able to join two different sizes together, but also be able to use it when both sizes are the same.

Here are the key parameters I want to control:

*   **Two Tube Diameters:** I need to specify both the *outer diameter* of the tube for each side of the coupler. Let's call them `A_TubeOuterDiameter` and `B_TubeOuterDiameter`.
*   **Optional Lip Rings:** I want an optional *lip ring* on each end that extends beyond the tube to hide the hose end. I want to be able to turn these on or off for each end individually and control the *inner diameter* of the lip ring. Let's call these `A_RingInnerDiameter` and `B_RingInnerDiameter`, and flags `A_IncludeRing` and `B_IncludeRing`, respectively.
*   **Barb Height:** I need to control the height of the little barbs that grip the inside of the hose. Let's call these `A_DentHeight` and `B_DentHeight`.
*   **Barb Spacing/Length:** I also need to control the distance between the barbs on each side; let's call these `A_DentLength` and `B_DentLength`. I would like to specify this as a percentage of the ring's inner diameter, if a ring is included.
*   **Wall Thickness:** I need to be able to control the overall wall thickness of the coupler, so let's call that `Thickness`.
*   **Cutaway View:** Also, I want to be able to make a cutaway version, for display purposes, that's a 180-degree arc instead of the full 360. Let's call that parameter `Cutaway` with possible values "Yes" or "No".

I'd like the design to be robust, so ensure the interior of the coupler smoothly transitions between tube diameters when those diameters are different. If a lip ring is not included then the inner surface of the coupler should continue uninterrupted to the end without creating any step. I’d also like the inside diameter to be consistent along the length of the barbs and on the outside to have a smooth transition from the barbs to the edge.

The coupler should have three barbs per side, with a smooth tapered transition on the ends of the barbs.

I would like the final object to be the union of two separate coupler pieces, mirrored so that they face each other and connect properly. I do _not_ want to use any libraries, please, I want all the code included in one or two files.

I'm looking to design a wire standoff for a model railroad. I need something that can hold two parallel bus wires away from the baseboard, and I'd like the design to be customizable. I'm picturing a bracket with slots to hold the wires in place.

Specifically, I'd like the design to have these parameters:

*   **Overall Bracket Dimensions:** I need to be able to adjust the overall width and height of the bracket.
*   **Mounting Flange:** I want a flange at the bottom for mounting to the baseboard, and I need to control the flange depth. Also, add screw holes for mounting - countersunk would be great.
*   **Slot Placement:** I want to control the vertical distance of the two rows of slots from the bottom of the bracket. Each row should hold two wires, so there should be 4 slots per bracket in total - 2 on each side.
*  **Slot Size:** I need to set the width of each slot for the wires.
*  **Wire Hole Diameter:** I need to specify the diameter of the circular hole at the end of each slot where the wire sits.
*  **Wire Separation:** I need to control the horizontal distance between the two wires in each row.

So basically, I need to be able to easily adjust the following:

*   `b_width`: The overall width of the bracket
*   `b_height`: The overall height of the bracket
*   `flange_d`: The depth of the mounting flange
*   `offset1`: The distance of the first row of slots from the bottom of the bracket
*   `offset2`: The distance of the second row of slots from the bottom of the bracket
*   `slot_w`: The width of the wire slots
*   `hole_diam`: The diameter of the wire holes
*   `wire_sep`: The distance between the wires in each row

I'd also like it if you could include the mounting screw holes, as mentioned. The screw holes should be countersunk. Please generate the appropriate parametric OpenSCAD files, I'm imagining that at least one file would define the bracket and another would handle the screw mounting. I don't have any libraries in mind so please just write standard OpenSCAD.

*   **Text Input:** I need to be able to specify either a single letter or a full name as text input. I'd like a parameter to switch between the two modes, maybe like a dropdown menu labeled "p" with options "name" or "letter".
*   **Text Properties:**
    *   Text size, in millimeters.
    *   Font selection; I'd like to be able to select any font that is available for OpenSCAD.
    *   Horizontal alignment (left, center, right).
    *  Vertical alignment (top, center, bottom, baseline).
    *   Letter spacing.
    *   Text stretch in both x and y directions.
*   **Stencil Box:**
    *   Width and height of the rectangular stencil box, in millimeters.
    *   Thickness of the stencil, in millimeters.
    *   Left-side border between the edge of the box and the text, in millimeters.
    *   Vertical height of the letters within the box. I want the letters to be a specified distance up from the bottom edge.
*   **Advanced Features:**
    *   Vertical spacing between lines of text.
    *  Maximum characters per line, this should cause the text to wrap if there is more than the max characters per line.

I'd like the script to be fully parametric, meaning I can change any of these values and the stencil will regenerate correctly. If it helps, I can give you a basic example .scad file that is close, but lacks certain features. Thanks!

//Please thank Kimberly Geswein for the KG font.  She gave me an ok over email to use this font.  KG is very close to the printing style we learn in kindergarten. I've uploaded the font for you to use with opencad(Thingverse customizer will not allow me to upload it). You can add your own font but you are on your own...
