I'm looking to design some modular whoop gates for FPV drone racing, and I'd like to do it parametrically so I can easily customize them. I've got some specific ideas in mind for how the gate should be constructed, and I'd like to incorporate a few different mounting options as well.

Here's the breakdown:

**Core Gate Segment:**

*   The basic building block of the gate is a segment that will connect to others to form a polygonal shape. The number of sides/corners should be a parameter, and that parameter should determine the angle between each segment. For example, if I specify 6 corners, the segments should create a hexagon.
*   Each segment should have a length parameter (sideLength).
*   Each segment will have a width and height (width and height parameters).
*   Each segment has a channel on the inner edge to hold LED strips. The channel should have an inner and outer dimension (ledChannelInner, ledChannelOuter) and a channel width (ledChannelWidth) that defines the space for the strip and the diffuser.
*   Each segment should include "restrainers" which are small rectangular extrusions on the top and bottom surface to help hold the LED strip in place. The length and width should also be parametric (restrainerLength, restrainerWidth).

**Connection Mechanism:**

*   The segments should connect to each other using a dovetail-like joint. The dovetail should be parametric (doveTailLength, doveTailWidth, doveTailShort) and include a tolerance (doveTailTolerance) for a good fit. The dovetail should be at the end of the segment such that it connects to the next one in the chain.

**Mounting Options:**

1.  **Stand:**
    *   A simple stand that the gate can slide into. This stand should be a rounded base and have a slot that is the same width as a segment. The slot should be a bit taller than the gate segment so it doesn't touch the bottom of the stand.
    *   I want parameters for stand length (standLength), stand width (standWidth), wall thickness (standWall), base thickness (standBottom), and the internal diameter of the slot (standInner).
2.  **Magnetic Mount:**
    *   A mount that can hold magnets, so the gate can be attached to metal surfaces.
    *   The magnets should be held in a rectangular slot.
    *   I'd like to define the dimensions of the magnets (magnetLength, magnetWidth, magnetHeight).
    *   The mount should have an offset to hold the magnets in the top half of the mount, and have some "hooks" to keep the magnets secure. I'd also like to parameterize the hook thickness, length and width (magnetHookThickness, magnetHookLength, magnetHookWidth).
    *   I'd like to specify the wall thickness around the magnet hole (magnetWalls).
    *   The number of magnets in the mount should also be a parameter (magnetCount).
3.  **Battery Mount:**
    *   A mount designed to hold a battery, attached with a rubber band.
    *   Like the magnetic mount, it should have magnets on the outside to stick to a magnetic surface.
    *   The width of the rubber band should be parametric (rubberBandWidth)

**Other Considerations:**

*   I want to be able to specify which part to render (gate segment, magnet mount, stand or battery mount, or all parts).
*   The design should print without supports.
*   I will want to set `$fn` for smoother curves.

Could you please generate a set of OpenSCAD files that implement this design, complete with the parameters mentioned above? I think it will be pretty complicated to do all in one file, so using different files and `use` statements will be good. I'd prefer to avoid additional libraries if possible, so please stick with the core functionality in OpenSCAD. I am assuming you are going to generate all the code from scratch.

I'd like to create a wall-mounted clip, primarily for holding cylindrical objects like toothpaste tubes. I envision a design that includes a circular clip section and a flat mounting plate. The clip should have a variable opening to allow for different sized tubes, and it should be possible to add a screw hole for secure mounting.

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

**Clip:**

*   **`dia` (inner diameter):**  This will define the inner diameter of the clip's circle where the tube will sit. I'd need to adjust this depending on the diameter of the tube I'm holding.
*   **`openRatio`:**  This will determine the size of the gap in the circle for inserting the tube. A ratio of 1 would be a complete circle, and anything less than one would define the opening.  I'd expect to use a value around 0.9.
*   **`w` (wall thickness):** The thickness of the material forming the clip and the mounting plate.

**Mounting Plate:**

*   **`mountX`:** The length of the mounting plate along the x-axis.
*   **`y`:** The overall height of the design including both the circular clip and the mounting plate.
*   **`screwable`:** A boolean to enable or disable a screw hole.

I'd like to be able to specify these values in a customizer.

The design should use a `clip` module to create the semi-circular part and a `wallMount` module to add the mounting plate and optional screw hole. I will also need a `screwHole` module to create the conical screw hole if `screwable` is `true`. The `clip` module should use a difference between two circles to form the base clip, and then add small semi-circular shapes at the ends to create a rounded look and a slightly stronger clip.

Could you please generate the OpenSCAD files for this? I'm not using any external libraries at this time.

I'd like to create a parametric "impossible cube" design in OpenSCAD, but I want something a bit more robust and customizable than just the basic version. The basic idea is that you have a cube shape where the edges appear to pass through each other in a paradoxical way, sort of like a skeleton cube made of intersecting bars.

Here's what I'm envisioning:

1.  **Core Structure:** The basic structure will be a cube, defined by a `length` parameter, which determines the size of the "impossible" inner cube.

2.  **Swept Profile:** Instead of just using simple bars for the edges, I want a swept profile. I want to control the thickness of these bars using a `thick` parameter. This profile will be offset from the edges of the cube by a `space` parameter.

3.  **Profile Shape:** I want a `curvy` boolean parameter to switch between a square/rectangular profile (basically a box of `thick` dimensions) and a circular/spherical profile (using cylinders and spheres capped at the ends with more spheres). The circular version should have the same 'thickness' specified by the `thick` parameter (so, for example, a cylinder of diameter `thick`).

4.  **Orientation:**  I want a `corner` boolean parameter that allows the cube to be oriented either flat on a face, or balanced on a corner.  This corner orientation is preferred for 3D printing without supports. This should be done with rotations only.

5.  **Parametric Design:** I want all the dimensions to be fully parametric and modifiable, and I'd like it to be clean and easy to adjust the `length`, `thick`, and `space` parameters.

6. **Units:** I intend to use mm for all measurements.

7. **Libraries:** I don't have strong library preferences for the basic functionality, but if there's an existing utility library that simplifies rotations or some other aspect of the design, I'm open to using it.

I'd like the final output to be a single `.scad` file, or a small number of `.scad` files that import and build upon each other if needed, but all are organized for easy modification. I'm not looking to create a complex library at this point - I'd prefer to have a single easily-modified project file.

I'm looking to create a set of very simple, fast-printing flat wrenches for use with eurorack modules. I've attached the scad file of the current design I'm using, but it's pretty basic and I'd like something more parametric. I need to be able to easily adjust the nut size, tool height, tool length, head margin and printing margin to accommodate variations in hardware and printer tolerances. I'd like to be able to generate wrenches quickly and easily for different sizes. I only need wrenches for hex nuts.

Specifically, I'm looking for an OpenSCAD design, or set of designs, that will allow me to input the following parameters:

*   **Nut Size (mm):** The size of the nut the wrench is intended for.
*   **Tool Height (mm):** The thickness of the wrench.
*   **Tool Length (multiplier):** A multiplier that controls the overall length of the wrench. This length should be based off of the nut size so that a higher multiplier makes the wrench longer.
*   **Head Margin (mm):** The amount of extra space around the nut head to accommodate printing tolerances and provide a little wiggle room.
*  **Kerf (mm):** Printing margin or the amount of space to add when cutting out parts of the model to account for variations in print material being thicker than they should be.

The wrench should have a simple design with a closed end. It should have a hexagonal cutout to fit the nut. The wrench head should be a little wider than the nut, and the handle should extend from there. The "handle" and head section should be joined, and should be cut out in a way that the wrench could be printed on a flatbed, without needing supports.

I'd like the OpenSCAD design to use the `shapes.scad` library from MCAD, if possible. I don't think it should be too complicated of a design, so I don't think I'll need any other fancy libraries. I don't need multiple wrenches in the same file or any kind of array of wrench sizes. If it's a bit cleaner to do each wrench in its own file, that's fine with me.

I'm looking to create a customizable garden plant label stake using OpenSCAD. I'd like it to be parametric so I can easily adjust the text, font, stake size, and other dimensions.

Here are the key features I want:

1.  **Text Label:**
    *   The text should be customizable (e.g., "Tomato", "Basil").
    *   I need to be able to control the text size and thickness.
    *   I need to be able to choose the font. I'd like to be able to specify a specific font face and style like "Nimbus Sans L:Bold".
    *   I need to be able to adjust the vertical offset of the text relative to the stake.

2.  **Stake:**
    *   The stake should have a customizable length, thickness, and height.
    *   It should have a pointed end to make it easier to push into the ground.
    *   I'd like to be able to control the length of the pointed section and the size of the very tip.

3.  **Overall Structure:**
    *   The text label should be attached to the top of the stake.

I'm basically looking to recreate the functionality of the attached `garden-sign.scad` file, but I'd rather have you generate a new parametric file. Can you help with this? I don't need any extra libraries - just something that can be easily customized and produces a well-formed STL. Also, don't worry about the detached dots on i's and j's; I can deal with those in the slicer. I need it to be fully parametric, not just a single object.

I'd like to create a customizable key tag generator in OpenSCAD. The basic idea is a rounded rectangle shape with a hole for attaching to a keyring and some raised text on the surface. I'm imagining a couple of key parameters: the text itself, the font used, and a way to adjust the text's "spread" (how wide the letters appear).

Specifically, I need the tag to be generated with a rounded shape using a `hull()` of cylinders, with a keyring hole on the left side, a cylinder in the center, and a final cylinder to the right. This gives that elongated oval shape. There needs to be a hole going all the way through the keyring cylinder. The text should be on top of the base shape, raised using `linear_extrude`. It will need the `text()` module, of course.

I would like to be able to control the `text` string itself, the `font_face`, and `spread_factor`, as seen in my example, as well as `font_size`. In that example the fonts are listed, which gives a good idea of the breadth of possibilities for fonts (although not all may work well). The parameters should be such that the tag length adjusts to fit the text, so a long word won't get cut off.

[Assistant]
key_tag.scad:
```
// This module creates a labeled tag for use with keys or luggage

// Text to write on tag
tag_text = "KEYS";

// Width scaling for fonts

I'd like to design a parametric plant label that I can print. It needs to have a label area with two lines of text and a stake that goes into the ground.

Here are the specific requirements:

**Label:**
*   The label should be rectangular, with rounded ends.
*   It needs to have two lines of text. The top line should be configurable, both in content, font, and font size. The bottom line of text should also be configurable in content, font, and font size, though it can have a different font and size from the top line. There should be a configurable vertical spacing between the two lines of text and a configurable vertical offset for the top text line.
*   The text should be raised above the surface of the label, with a configurable height.
*   The overall dimensions of the label (width and length) should be parametric.
*   The height (thickness) of the label should also be parametric.

**Stake:**
*   The stake should extend from the bottom end of the label, with a smooth transition.
*   The stake should be a simple rectangular prism, with a configurable width and length.
*   The very end of the stake should taper to a point so that it can easily push into the ground. I think a cone shape would be best here, or possibly a triangular pyramid.
*   The label and the stake should be a single continuous piece.

**General:**
*   All dimensions should be in millimeters.
*   I'd like all of the relevant dimensions to be easily configurable via variables at the top of the .scad file(s).
*  I'd prefer to have just a single .scad file if possible.
* I want the text to be centered in the label area.
* The font sizes used in OpenSCAD are in points rather than pixels, and I need to multiply them by 0.75 to get a proper size. This should be done internally to the scad file, so that I can enter the pixel size I want.

I'm not sure which OpenSCAD libraries I should use for something like this. I don't think I'd need anything too fancy, maybe just some basic text extrusion and a cone/pyramid primitive at the bottom of the spike.

Hi! I'm looking to create a parametric ball joint design in OpenSCAD, and I'd like it to be pretty flexible. I've seen some good examples online, but I want to be able to control a few specific things.

First, I need a ball component. I'd like to be able to set the diameter of the ball and the height of the neck above the ball where the screw thread starts. I also need to be able to turn the thread rod on or off, and specify the screw diameter and length if the rod is turned on.

Next, I need a matching ball nut component. This should obviously have the correct internal threads to mate with the ball's thread rod, and I'd need to be able to specify its thickness and a tolerance value to ensure a good fit.

Then I also need a socket component to hold the ball. I need to specify the height of this socket as well as the gap between the ball and the socket for smooth movement. Also, I'd like to be able to add an optional mounting plate to the socket base with adjustable dimensions for the plate's size, thickness, and hole locations for mounting screws.

Finally, I need a socket nut to match the socket component. I need to be able to set the tolerance of this nut.

Essentially, I need separate modules for each of these components (ball, ball nut, socket, socket nut), and I'd like to have global parameters to set things like the smoothness (using `$fn`) and a gap value to use between parts. It would also be helpful to have a demo option to show all of the parts together for testing.

I'm not too concerned about the specific shapes of the mounting plates at this point, and I only need a simple circular profile for the ball and socket components.

For the threading, I'd like to use the code from this thingiverse: https://www.thingiverse.com/thing:2158656. Specifically, I need the `iso_thread` module and its helper functions. I can't include the file here, so you'll need to grab the code from there. I also need the standard hex nut size function, `iso_hex_size`, and the function to determine the standard course pitch of the threads, `iso_pitch_course`.

Could you help me generate this design? I'd appreciate a well-structured parametric design that's easy to modify.

Okay, I'm looking to create a customizable tripod design in OpenSCAD, and I'd like it to be parametric so I can easily adjust various dimensions. I've got a pretty good idea of the basic structure, and I'll give you the details. It should have a central body with brackets that hold the tripod legs and the legs should hook onto rods extending from the body's brackets.

Here's a breakdown of what I'm looking for:

**Overall Structure:**

*   The design should consist of three main parts: the central body/bracket assembly, three identical tripod legs, and optionally, test print parts.
*   All parts should be designed to be printed without supports.
*   I want to be able to adjust the smoothness of curves using the `$fn` variable, using values like 48 (low), 80 (medium), and 120 (fine). I'd like to be able to set this via a "smooth" variable that will drive `$fn`

**Body and Bracket:**

*   The central body should have a cylindrical main section with three brackets extending outward to hold the legs.
*   I need to be able to specify the diameter of a central hole through the body, using a `hole_dia` variable, along with the wall thickness around this hole (`hole_wall`).
*   The brackets should have a specific thickness using `bracket_thk`, and the rods that the legs hook onto should have a diameter using `bracket_rod_dia`.
*   There should be a small gap (`part_gap`) between parts, which should be adjustable.
*  I'd like to add a small bevel to all the edges (`part_bevel`), which can be set to zero.

**Tripod Leg:**

*   The legs should have a defined length (`leg_leng`), an end diameter (`leg_end_dia`) and the thickness of the leg itself should be adjustable via a `leg_thk`.
*   The hook at the top of the leg that attaches to the bracket rod should be adjustable. Specifically, the gap between the rod and the hook should be adjustable with `leg_gap`, and the hook's wall thickness (the thickness of the material making up the hook) should be set using `hook_wall`.
*  There needs to be a "stopper" on the leg that prevents it from rotating too far when it's connected to the bracket. This stopper should have a defined width `stopper_wid` and should be at a defined angle `stopper_angle` relative to the leg.
*  I'd like an option for an anti-slip feature on the end of the leg. This should be a boolean (1 for yes, 0 for no) set with an `anti_slip` variable.

**Additional Points:**

*   I'd like to have a variable `part` to choose which of the three parts I'd like to generate; with '0' generating a demo assembly, '1' for just the body/bracket, '2' for an individual leg, and '3' for a test print of part of the body with a leg.
*   I'd like all parts to be placed at the origin when generated
*   I don't need to use any external libraries at this time.

I think that covers everything. I'm excited to see what you come up with!

Hey there, I'm looking to create a parametric design for a thread-cutting tool that uses a circular razor blade, like the ones used in fabric cutting. I’ve got some ideas about the shape and how it should hold the blade, inspired by a design I saw online, but I need it to be fully customizable.

Here’s the breakdown:

**Core Functionality:**

The tool needs to hold a circular blade (either 28mm or 45mm diameter). The blade needs to be securely held, but also easily removable for replacement. The tool will use a screw and nut for securing, but a design that can easily be modified to use a rivet could also be useful.

**Key Components:**

1.  **Holder:** This is the main body of the tool. It should have a circular cutout in the center to hold the blade. The sides should include “heart” shaped segments to hold the blade secure, and a central hole to be used to attach the holder with the screw.
2.  **Blade Door:** A removable door that sits on top of the holder. This door should hold the blade in place.
3.  **Screw/Rivet:** A hole needs to be included for a screw and nut. The user should be able to modify the dimensions of this hole easily, and ideally the design should be easy to modify to accommodate a rivet instead.

**Parametric Variables (at minimum):**

*   `blade_diameter` (e.g., 28 or 45 mm) - Diameter of the circular blade.
*   `blade_thickness` - Thickness of the blade.
*   `holder_diameter` - Outer diameter of the main holder.
*   `holder_thickness` - Thickness of the main holder.
*  `cutting_slits` - The number of segments in the tool
*   `screw_diameter` - Diameter of the screw hole.
*   `edge_rounding` -  Radius for rounding the edges of the holder.
*  `door_diameter` - Diameter of the blade door
*  `door_thickness` - Thickness of the blade door
*  `door_looseness` - Allowance factor when creating the door

**Specific Design Features:**

*   The heart shape should be adjustable so that the user can control how aggressive it looks, and how much of the blade is exposed.
* The blade door should be able to have small cylinders removed from it.

**Output:**

I’m looking for a parametric OpenSCAD file (or files, if that makes sense) that I can customize to create various sizes and shapes of this tool. I don’t need to work with existing files - just create them from scratch.

I'd also like to make sure that I can use the design with the MCAD library, so any parts you think might benefit from that inclusion would be great.

Let me know if you need any more clarification or want to discuss any of this before you start. Thanks!

Hey, I'm looking to get a parametric foot designed for 3D printing. I've seen some examples online but I'd like one that's a bit more flexible. It needs to have a base, a tip, and a countersunk hole for a bolt.

Specifically, I'd like to be able to adjust the following:

*   **Base diameter:** The diameter of the base of the foot.
*   **Tip diameter:** The diameter of the top of the foot.
*   **Internal diameter:** The diameter of the main bolt hole. This should be a clearance fit for the bolt shank.
*   **Internal step diameter:** The diameter of the countersunk portion of the bolt hole. This should be a clearance fit for the bolt head.
*   **Total height:** The overall height of the foot.
*   **Step height:** The height of the countersunk section from the base.

I would also like the code to be well-commented. I'd like to use OpenSCAD to do this. I'm not sure if any libraries are needed, but if they make the code more readable I'm fine with that. The example code I've seen online used a rotate_extrude with a polygon, if there's a more straightforward way to make a cone shape I'd be interested to see that.

I need an OpenSCAD design for a shim, similar to the attached code but with a few more customizable features. Essentially, it's a rectangular block with rounded edges, two holes, and a variable thickness.

Here are the parameters I need to control:

*   **shimThickness**: The overall thickness of the shim.
*   **shimLength**: The length of the rectangular base.
*   **shimWidth**: The width of the rectangular base.
*   **filletRadius**: The radius of the fillets (rounded corners).
*   **holeDiameter**: The diameter of both holes.
*   **hole1OffsetX**: The horizontal offset of the first hole from the edge of the shim.
*    **hole1OffsetY**: The vertical offset of the first hole from the edge of the shim.
*    **hole2OffsetX**: The horizontal offset of the second hole from the edge of the shim.
*   **hole2OffsetY**: The vertical offset of the second hole from the edge of the shim.

I'd also like to be able to specify the number of segments used when generating the fillets. I guess this could be a standard `$fn` parameter.

I'd also like the design to be easily modifiable, so using some kind of parameter structure would be great. It's also important that the holes go all the way through the shim. Could you make sure the code uses the minkowski function for the rounded edges and difference functions for the holes? Finally, could the design be centered around the origin?

I'm looking to create a vinyl roll holder, similar in concept to the "Ultimate Spool Holder" but adapted for flat rolls rather than spools. I've seen a design that uses 608 bearings and a curved frame, but I want to be able to customize it more easily and have the design generated from scratch.

Specifically, I need a design that holds two bearings, with the bearings mounted horizontally. The design should consist of a base structure that cradles the bearings, and the bearings will be attached by inserting them into circular holes with a tolerance adjustment so that the bearings will fit snugly.

Here are the key parameters I want to control:

*   **Bearing Dimensions:**
    *   Outer diameter of the bearing. Defaults to 22mm (for 608 bearings).
    *   Inner diameter of the bearing (the hole). Defaults to 8mm (for 608 bearings).
    *   Thickness of the bearing. Defaults to 7mm (for 608 bearings).

*   **Holder Dimensions:**
    *   Wall thickness of the main structure (the base and vertical parts).
    *   Distance between the centers of the two bearings.
    *   Rounding radius for the bottom corners of the base.
    *   Margin around the bearing's outer edge, to have a slight recession.
    *   Radius of curvature of the curved edge between the two bearing supports.
    *   Thickness of the spacer between the bearing and the outer wall.
    *   Distance from the bearing to the bottom edge of the base.

*   **Tolerance:**
    *   A parameter to adjust the fit of the bearing in its mounting hole. This would be a value to add or subtract from the bearing's inner hole radius.

*   **Facet Detail:**
     * Minimum facet size and minimum facet angle for smoother curves.

The main structure will have a curved shape connecting the two bearing mounts, and should also have a base with rounded corners. The design needs to be parametric so I can change all of these dimensions easily, and I'd like to be able to print this multiple times to use with several rollers.

I would like this created with standard OpenSCAD primitives, but I'm also okay with libraries. If a library would be helpful, I would prefer using BOSL2 if possible, but I can use other libraries if needed. Please provide a complete .scad file or multiple files if the design needs to be modular.

Also, I'm hoping this can be designed from scratch instead of attempting to improve the existing design.

Hey, I'm looking to get some custom drawer organizers designed in OpenSCAD. I've been playing around with a simple box customizer, but I need something more flexible. I'd like a system that lets me define a base box and then customize the internal compartments more precisely.

Here's what I'm thinking:

1.  **Base Box:** I need to be able to define the overall dimensions (length, width, and height) and wall thickness of the outer box. This part should be similar to what I have already.

2.  **Compartment Definition:**
    *   I want to specify a series of compartments within the box.  Instead of just dividing the space with simple dividers, I would like to define compartments using a combination of vertical and horizontal walls. Think of it like building a grid inside the box.
    *   For each compartment, I should be able to specify:
        *   Its position within the box, perhaps by using a grid system (e.g., "row 1, column 2").
        *   Its dimensions (length, width, and height). The height of internal compartments should be able to vary (so, you can have shallower trays for some stuff and taller sections for others).
        *   The thickness of the compartment walls.
    *   It should be possible to define multiple compartments of different sizes in the same box, and even nested compartments.

3.  **Wall Treatment:**
    *   The compartment walls should have options for how they connect to the outer walls or other compartments. Options could include full-length walls, walls that stop short (creating a small opening for access underneath), walls that merge into other walls, etc.
    *   I would also like an option to add fillets to the inner corners of the compartments.

4.  **Cut-outs:**
   * I'd like to have the ability to define custom cut-outs (rectangular, round, or even a user-defined shape by providing a 2D DXF path) on the walls of individual compartments and also on the main box walls. These should also be able to use fillets.
   * It would be great to have options for inset or through cuts.

5.  **Parametric Design:** Everything must be fully parametric. I need to be able to tweak parameters like the base box size, number of compartments, their dimensions, wall thicknesses, etc., and have the whole thing update automatically.

6. **Libraries:** Please use the `BOSL2` library, I am familiar with it.

Essentially, I'm looking for a modular system where I can design a custom box with a specific arrangement of compartments to organize items of different shapes and sizes. I'm thinking of things like small electronic components, screws, coins, etc. I also have a 3D printer and am hoping to print this thing without too many support issues (some thought towards that while designing would be awesome, I guess). Let me know if you have any questions about what I have in mind, this is really just the first brain dump. I'm hoping to make a variety of configurations with this system.

Hey, I'm working on a modular box system in OpenSCAD and I need some help designing it. I've been inspired by Chappel's designs and some of Niptrion's work. My goal is to create a stackable, customizable system where each "unit" of the box is a square.

Here's what I'm looking for:

**Core Functionality:**

*   **Parametric Design:** The design should be fully parametric, allowing the user to control all dimensions and sizes via variables.
*   **Modular Units:** The box will be made of a grid of square units. For example, a "2x3" box would be 2 units wide and 3 units long.
*   **Unit Size:** Each unit should be a square, and I want a single parameter, let's call it `width`, to determine the size of one side of that square. A 1x1 box would be `width` x `width`.
*   **Wall Thickness:**  There should be a parameter `thickness` to control the wall thickness of the box.
*   **Height:** The overall height of the box should be controlled by a `height` parameter.
*   **Rounded Corners:** I'd like rounded corners, with the radius controlled by a `radius` parameter, and I need those to be elongated a bit (like the provided scad) to be better for printing (that is, no supports)

**Stackability & Structure:**

*   **Grid Connection:** The boxes should have a system of cutouts on the sides to allow stacking and connecting with other boxes of the same design. These cutouts should have the same curvature as the exterior edges of the box, and ideally, there should be a way to have grid pieces that will allow different boxes to connect to each other.
*   **Recessed Stackable Top:** The top of the box should be designed so that another box of the same type can fit securely inside (a slightly larger outer edge, basically).
*   **Box Unit Parameters:** I want parameters `XCount` and `YCount` to control the number of box units in the X and Y directions, respectively. A `XCount = 2`, `YCount = 3` would create a box with a 2x3 grid.

**Additional Features (For later):**
*  I want to have the ability to easily add a handle/label holder recessed inside of the box, which will not impact stacking.
*  I might also want to design a lid in the future.

**Specific Parameters:**
*   `width`: Width of a single unit (e.g., 50mm default).
*   `height`: Overall height of the box (e.g., 25mm default).
*   `radius`: Radius of the rounded corners (e.g., 4mm default).
*  `thickness`: Wall thickness (e.g., 2mm default).
*   `XCount`: Number of units in the X dimension (e.g., 1 default)
*   `YCount`: Number of units in the Y dimension (e.g., 1 default).

I am not using any libraries at this time.

Could you generate the necessary OpenSCAD files for this design? I think I'll need at least one main file. Thanks!

Hey, I'm looking to create a customizable battery case using OpenSCAD, and I'd like your help. I have a pretty specific idea in mind, building on a design I found but want to be able to adjust many parameters.

First off, I need to be able to specify the battery type, either as a preset like AA, AAA, C, D, F, N, JJJJ, CR123, CR2, 18650, or 26650, or with a custom diameter if none of those work. There should be a diameter tolerance adjustment as well.

The case itself needs to have parameters for the number of battery rows and columns, the thickness of the side walls and lip, the recess height for the batteries, and the thickness of the bottom layer.

For the lid, I want to choose between no lip, a positive lip, or a negative lip. Then I also need settings for the lip's height, the gap between the top and bottom pieces where they overlap, and a chamfer for the lip.

Magnets are also an option, with the user being able to choose between round or square magnets, and specify the diameter and height of the magnets. Or, the user could specify no magnets at all.

Finally, I need labels on the case, with different text options, font choice and font size. Text modes should include options like "None", "Auto Variant-1", "Auto Variant-2", "Auto Variant-3", "Auto Variant-4", and "Custom". Custom text should be configurable with two lines of text. There should be a choice of font, font size, the sides on which to place the text and whether it should be embossed or extruded, a position for the text, and whether the text should be flipped. The user should be able to specify the space between lines of the text and the depth (emboss/extrude) of the label. Also, it should be possible to specify the vertical and horizontal positioning of the text.

I think this might be a pretty complex design, but hopefully you can help me out. I do *not* need to use the BOLTS library for this design. I'd like a single OpenSCAD file to achieve this functionality, if possible.
