I'm looking to create a bayonet lock mechanism using OpenSCAD, similar to the one I've seen in aviation hardware. I need a parametric design that allows me to generate both the "lock" and the "pin" components.

Here are the main requirements:

1.  **Two Parts:** The design must produce two distinct parts: a "lock" with slots and a "pin" that fits into those slots.
2.  **Pin Direction:**  I need the option to have the pin oriented *inward* or *outward* relative to the lock cylinder.
3.  **Lock Count:** I need the option to create the lock and pin with either two or four locking mechanisms.
4.  **Parametric Design:** Everything should be adjustable using parameters:
    *   `inner_radius`:  The inner radius of the lock.
    *   `outer_radius`: The outer radius of the lock.
    *   `conn_height`: The height of the main connecting cylinder of the parts.
    *   `lip_height`: The height of a small lip at the bottom of the part (optional, and can be set to zero if no lip is required).
    *  `lock_angle`: The rotation angle of the locking arms.
    *   `gap`: The gap between the pin and lock pieces (this is critical for 3D printing tolerances).
    *   `detail`: The number of facets for smooth curves (48 is a good starting point for FreeCAD compatibility).
5.  **Secure Locking:** Incorporate a small bump on the locking arms to help hold the pin in place.
6.  **No Spring Required:** The mechanism will rely on the shape of the parts themselves for securing, not a spring.

I'd like the OpenSCAD file(s) to be structured so that it's easy to specify whether I'm generating the lock or pin part, and whether the pin is inward or outward facing. It should also allow me to choose the number of locks, and tweak the parameters as described above.

It sounds like a fairly complex design, but it should be feasible with OpenSCAD. Let me know if you need any clarification.

Hey, I'm working on a box design in OpenSCAD and I'm trying to make something with curved edges, like rounded over corners, but also with a bit of a twist. I've got a really basic start but I think I'm doing something wrong with `linear_extrude` and honestly I'm not sure how to best parameterize it.

Here's the starting point I've got in `Curved_square_box.scad`:

```
boxSize=100;
thickness=4;

difference() {
    // Outer box
    linear_extrude(height=boxSize, center=false, convexity=30, twist=15, slices=200)
    square(boxSize);
    // Inner box
    translate([0, 0, thickness])

    translate([thickness, thickness, 0])
    square(boxSize-2*thickness);
}
```

I'd like to be able to control a few things:
*   The overall `boxSize` (making it a cube)
*   The `thickness` of the walls
*   The amount of `twist` in degrees
*   The `radius` of the rounded edges. I'd prefer if the rounding was applied to the top and bottom edges too, rather than just the corners.
*   Also, the extrusion height should match the `boxSize`.

I'd really like this to be a fully parametric design, so I can change these values and have the box update correctly. I don't have a strong preference on how many files are used, but it would be great if it was readable. I'd like to avoid using any libraries if that's possible.

Can you help me out with this? Thanks!

Hey, I've been playing around with OpenSCAD and I'd like to see if you can help me create a parametric design. I'm looking for a twisted box, essentially a square prism that rotates as it extrudes upwards.

The key features I need are:

*   **Box Dimensions:** I want to control the overall size of the square base and the total height of the box.
*   **Thickness:** I need to be able to specify the wall thickness of the box, creating a hollow interior.
*   **Rotation:** The twist angle needs to be adjustable, determining how much the square rotates as it's extruded up.

To be more specific, the box should be created by extruding a square, then subtracting another extruded square that's slightly smaller so that it creates a shell. I'm looking for all of the code needed to generate the model, not just snippets.

It'd be super helpful if you could provide me with a complete SCAD file for this, and please don't assume I have any libraries or anything installed - generate all the required code.

rotation = 15; // [15:45]

difference() {
    linear_extrude(height=boxHeight, center=true, twist=rotation, slices=boxHeight)
    square(boxSize, center=true);

    translate([0, 0, thickness])
    linear_extrude(height=boxHeight, center=true, twist=rotation, slices=boxHeight)
    square(boxSize-(2*thickness), center=true);

Hey, I'm looking to generate a customizable motherboard backplate using OpenSCAD. I've got an existing SCAD file that does most of what I want, but I'd like something more parametric, easier to adjust, and hopefully better organized.

Essentially, the backplate should have a main body with adjustable dimensions. Then I need to define cutouts for the various ports on the motherboard – these cutouts should be defined by their position and size, with the position being relative to one corner of the backplate. I'd also like a raised edge around the backplate that can have customizable height, thickness, and offset from the backplate edges. Finally, I would like to have snap-in dots on the raised edges, with the number and spacing adjustable.

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

*   **Backplate Dimensions**: `backbase` - A 3D vector for the backplate's width, height, and thickness.
*   **Cutouts**: `cutouts` - A list of 2D vectors. Each vector should represent a cutout's position (x, y) and size (width, height). The position of the cutouts should be relative to the origin (0, 0) of the backplate, but the backplate can be moved in the z-direction.
*   **Raised Edge**:
    *   `edge_thickness` - Thickness of the raised edge.
    *   `edge_height` - Height of the raised edge.
    *   `edge_offset` - Offset distance from the backplate's edges.
*   **Snap-in Dots**:
    *   `edge_dots` - A 2D vector representing number of dots along the length and height of the edge.
    *   `dotzratio` -  A ratio of the edge height used to position the dots vertically on the edges.
    *   `dotsize` - Radius of the snap-in dots.

I would like to be able to easily change these parameters without having to dive deep into the code. Also, any kind of modularity would be fantastic. I think it'd be useful to have separate modules for generating the base plate, cutouts, raised edges, and snap dots, that way they could be more easily manipulated and customized.

I'm pretty sure I'm going to need to do a difference operation to create the cutouts on the backplate, and I'll probably need a loop of some kind to draw the snap-in dots.

Could you generate an OpenSCAD file (or files) that achieves this? I don't need to do anything fancy with the files at this time; just give me the main module that would generate the backplate based on those parameters.

Hey, I'm looking to design a parametric coin holder for Euro coins, similar to the one I found on Thingiverse ([https://www.thingiverse.com/thing:3475742](https://www.thingiverse.com/thing:3475742)), but I need something from scratch that I can tweak a bit more easily.  It needs to use compression springs to keep the coins pressed up, so they don't fall out.

Essentially, it will be a series of vertical tubes, one for each coin denomination (50c, 20c, 10c, 5c, 2c and 1c), each with a spring at the bottom pushing the coins up.  I'd like to be able to set the minimum and maximum coin values to include, so I can choose, say, just the 1c and 2c, or the 5c to 50c.  The height of the coin stacks should be adjustable as well, as should the spring diameter and compressed spring length. I want to include tolerances on the coin diameter and height of coins. Finally, I need to specify the minimum wall thickness surrounding and in between the coin recesses.

So, the main parameters I need are:

*   `coin0`: The largest coin value to include (50c, 20c, 5c, 10c, 2c, or 1c, I can use an integer index like in the example, or a string, whatever makes sense).
*   `coinx`: The smallest coin value to include.
*  `h_max`: The maximum height of the coin stacks.
*   `h_follower`: The height of the spring follower (the platform that rests on the spring)
*  `d_spring`: The spring diameter
*   `lmin_spring`: The minimum compressed spring length.
*  `tol_d`: Tolerance added to coin diameter.
*   `tol_h`: Tolerance added to coin thickness.
*  `flesh`: Minimum wall thickness.
*  `h_body`: Total height of coin holder body, which should be automatically calculated from h_max, h_follower, lmin_spring and flesh.

I'd also like to be able to specify if I want to render the assembled version, the unassembled version, just the case, or just the spring follower disks. I also need the number of facets to be parametric to allow for faster rendering.

For the coin dimensions themselves, it would be great if you used a matrix like the example code, where each coin is defined by its value, diameter and thickness. And I need to be able to change this if necessary. The coin values are:

50c: 24.25mm diameter, 2.38mm thick.
20c: 22.25mm diameter, 2.14mm thick.
5c: 21.25mm diameter, 1.67mm thick.
10c: 19.75mm diameter, 1.93mm thick.
2c: 18.75mm diameter, 1.67mm thick.
1c: 16.25mm diameter, 1.67mm thick.

The design should use `linear_extrude`, `translate`, `rotate`, `difference`, `union`, `intersection`, `hull`, and `cylinder` primitives. It should also contain loops to generate the individual tubes and followers. I'd like to see the coin follower as a separate module too, and a module that defines the shape of the case itself, and a helper module for building a simple rectangular cuboid (just for convenience).

I'd really appreciate it if you could generate the OpenSCAD file(s) for me.

I'm looking for a customizable palette generator in OpenSCAD, specifically for holding small amounts of paint. I need to be able to control the size and arrangement of the individual paint wells, as well as the overall palette dimensions.

Here's what I'm envisioning:

*   **Individual Well Customization:**
    *   I need to set the inner dimensions (length and width) of each well. Let's call these `fieldLength` and `fieldWidth`.
    *   I need a `fieldHoleHeight` parameter to control how deep the well is.
    *   I need to control the inner radius (`innerRadius`) to have rounded edges at the bottom of each well.
    *   Each well should be surrounded by a wall of customizable thickness (`wallThickness`).
*   **Palette Arrangement:**
    *   I should be able to specify the number of wells in the X and Y direction, `fieldCountX` and `fieldCountY`, respectively.
    *   The entire pallette should have a height `palletteHeight`
*   **Labeling:**
    *   I want an option to add label areas next to each row of paint wells. The labels should have a customizable width (`labelWidth`).
    *   These label areas could also be recessed, with the amount of recession set by a `labelRecess` parameter. Set to 0 if I don't want recessed labels.
    *  Whether or not to include labels should be controlled by a boolean variable: `withLabels`
*   **Overall Palette:**
    *   The design should include a surrounding border around all the wells.

I don't need any specific libraries at the moment. Could you generate the SCAD code for this, please?

I need to design some parametric Lego-compatible beams with bends in them. I'd like to be able to specify the number of holes on each side of the bend(s), and I want to be able to choose between having one or two bends in the beam.

For the basic beam, it should have the standard Lego dimensions for the pegs and the holes.  I'd like to have the option for an easy-print version where the middle section is a bit taller, instead of the normal thinner version.  I am using OpenSCAD and don't have any existing modules except for the standard library. Could you help me create the necessary SCAD files? I am mostly looking for one main file which will have all the parameters I will need.

Also, could you make sure to use variables for all of the standard dimensions of the lego components like peg radius, hole radius, height, depth and such?  That will make things way easier to adjust in the future if needed! Also the pitch (distance between the holes/pegs).

I need a parametric bracket design for a heatbed. I'm currently using an Anycubic Ultrabase which is glued to the heatbed below, but this design should be adaptable for other heatbeds as well. The provided file, `ultrabase_bracket.scad`, is a good starting point.

The bracket needs to securely hold the Ultrabase (or similar heatbed) to the underlying heatbed, ensuring it stays flat and evenly attached. I want to adjust the bracket's dimensions via parameters.

Here are the specific parameters I need to control:

*   `base_height`: This will be the combined height of the ultrabase and the underlying heatbed, usually around 5.5mm, but I need to be able to adjust this value.
*   `bracket_width`:  The width of the bracket itself, I think around 25mm is good but I'll need to tune this.
*   `bracket_depth`: The depth of the bracket, around 8mm, I'll need to adjust that too.
*   `wall`:  This is the wall thickness, and 1.8mm seems about right, but I also need to be able to change this.

I'd prefer to work with a single .scad file that I can customize using OpenSCAD's customizer.

Also, I would like the design to have a thin lip extending over the top of the heatbed, so that when clamped, the heatbed is actually captured as opposed to held in place. I think the code in the original file is good, but a user should be able to set how much this lip extends out over the heatbed with a parameter named `lip_extension` and a default value of 0.2mm.

I would like the design to use the `linear_extrude` module from the BOSL2 library if possible to provide a clean way to extend a profile up to the designed height. I also think I'd prefer that the whole design is parametric from the outset so that other users can easily change the dimensions to suit their particular heatbeds.

[Assistant]
ultrabase_bracket.scad:
```
// Bracket for the anycubic Ultrabase
// makes sure the glued on base sticks flat and evenly to the heat-bed

/* [Size] */

// combined height of the ultrabase and heat-bed
base_height = 5.5; //[4.5:0.1:7]

// width of the bracket
bracket_width = 25; //[10:1:50]

// depth of the bracket
bracket_depth = 8; //[6:1:20]

// wall thickness
wall = 1.8; //[1:0.1:4]

difference() {
    cube([bracket_width, base_height + wall * 2, wall + bracket_depth]);
    translate([-0.1, wall, wall])
        cube([bracket_width + 0.2, base_height, wall + bracket_depth]);
}

Hi, I'm looking to design some dividers for my Dewalt and Craftsman "Tough Cases" - the ones with the dovetailed sides. I've already got a basic design in mind, but I need it to be parametric so I can adjust it for different sized cases and different insert needs.

The basic shape is a rectangle with a thin wall dividing the case into two sections and dovetails that match the case's inner dovetails. Here's a breakdown of the parameters I need:

*   **`length`**: The length of the main insert, not including the dovetails. This determines how much of the case it covers lengthwise.
*   **`width`**: The thickness of the divider.
*   **`depth`**: The height of the insert body, from the base of the case up.
*   **`divider_height`**: The height of the thin wall section on top of the insert.
*   **`dovetail_distance`**: This is the horizontal distance between the two dovetail positions on each side.
*  **`dovetail_width_bottom`**: The width of the dovetail at its base.
*  **`dovetail_angle`**: The angle of the dovetail taper, since the dovetails are wider at the top than at the bottom.
*   **`dovetail_offset`**: An offset parameter that adjusts the position of the dovetails inward or outward.

I also need to make sure the insert extends far enough into the other side of the case, so nothing slips past it.

I think I need to use cylinders to model the dovetails and use `rotate` to match the angles. I think using a `difference()` operation at the end to cut off the bottom half will help with making the part printable. I think using a single .scad file should be enough.

Could you generate the OpenSCAD code for me? I don't need anything fancy, just something that works and can be easily adjusted. I don't need to use any external libraries for this. I think I have everything I need within base OpenSCAD functions.

Okay, I'm looking to design a holder for Nintendo 64 controller paks (memory paks, rumble paks, and transfer paks). I've seen a few designs, but I'd like one that's parametric and lays flat, kind of like a tray, with a square base.

Here's the breakdown of what I need:

*   **Cart Slots:** The holder should have slots for the paks, arranged in a grid pattern. I need to be able to control:
    *   The number of slots per row (e.g., 4 slots, like the included `n64-controller-pak-holder.scad` file I sent.
    *   The number of rows (e.g., 2 rows, like the file I sent).
*   **Slot Shape:** Each slot should be designed to securely hold a standard N64 controller pak.
    *   The slot needs a cutout shape that matches the general form of an N64 pak. It does not need to exactly follow the contour, but it should be able to hold both the normal memory and rumble paks securely.
    *   The depth of the cutout should be customizable.
    *   The slots need to be angled slightly forward in order to make it easier to remove the paks.
    *   Each slot should have small "legs" for support that angle down towards the back of the tray.
*   **Base:** The base should be a flat, square shape that the slots are attached to.
*   **Materials:** Assume a 3D printing scenario; the code should use measurements appropriate for this use case.
*   **Transfer Paks:** The transfer pak is significantly larger, so it needs two slots deep to accommodate it. I don't need anything special to differentiate these, just let it take up the requisite slots.
*   **Parametric Design:** The whole thing should be completely parametric. I want to easily change the number of slots, the depth of the cutouts, the angle of the slots, the height of the legs, etc. through variables.

I'm not particularly attached to the details of how the code I sent is structured (although you can reference it to understand my design), but it would be good if I could specify the following variables: `cart_count`, `cart_rows`, `cup_height`, `cup_width`, `cup_depth`, `cart_hole_depth`, `support_legs_length`, and `cup_angle`. The `cart_count` and `cart_rows` should determine the overall size of the tray.

I'm fine with you making assumptions about the exact dimensions and stuff if you need to, but make sure the paks fit snugly. I also want to make sure that I can easily adjust all of the above to work for other similar scenarios, maybe for different types of game paks.

The OpenSCAD file(s) should be well-commented and easy to understand. I do not need any external libraries or packages.

Hi, I'm looking to design a patch cable organizer using OpenSCAD. I've seen a design that looks promising, but I need a parametric version that's a bit more flexible.

The basic idea is to have two rows of cylindrical poles that hold the cables, with a rounded base plate. Here are the specific features:

*   **Poles:**
    *   The poles should be cylindrical with a rounded top, achieved by adding a sphere on top of each cylinder.
    *   They should be arranged in two parallel rows, with a consistent space between each pole in a row to accommodate the cables.
    *   There should be a horizontal cylinder connecting each pole to its counterpart in the opposing row.
*   **Base Plate:**
    *   The base should be a rectangular plate with rounded edges.
    *   It should be large enough to accommodate all poles and their respective connections.
*   **Parameters:** I need to be able to control:
    *   `pole_count`: The number of poles in each row. This should be an integer value.
    *   `cable_width`: The width of the cables. This determines the gap between poles in the same row.
    *   `pole_dist`: The distance between the two rows of poles.
    *   `pole_height`: The height of the cylindrical part of the poles.
    *   `pole_width`: The diameter of the cylindrical poles.

Could you generate an OpenSCAD file that implements this design, allowing me to adjust these parameters? I would appreciate it if the code was well-commented so that I can understand the design. I don't need any special libraries beyond what's included in the standard OpenSCAD installation.

I'm looking to create a marble run system that's compatible with standard LEGO bricks. I need a parametric design in OpenSCAD so I can easily adjust things like marble size, brick length, and the overall layout. I've seen some similar projects, but I want to build mine from the ground up.

Here are the specific requirements:

*   **Brick Types:** I'll need three types of bricks: straight sections, downward sloping sections, and 90-degree turning sections.
*   **Parametric Brick Length:** The length of each brick type should be adjustable by specifying a number of "pins", like the existing Lego standard, with the length of a 2-pin brick being a fundamental parameter, so everything scales properly. This way I can use 2-pin, 3-pin, 4-pin etc lengths.
*   **Parametric Marble Size:** The design should accommodate different marble diameters. This should also control the width of the track.
*   **Clearances and Tolerances:** It needs to allow for a small gap between the marble and the walls of the track, as well as a small gap for brick connections to ensure printing works without perfect tolerances. These should be parameters that I can adjust.
*   **Integrated Supports:** The track should have built-in support structures for easy printing, hopefully without requiring external supports.
*   **Layout Control:** I'd like to be able to specify how many of each brick type I need (straight, bent, and downward-sloping) and the program should generate an efficient layout for printing with minimal wasted space.
*   **Brim Option:** I would like an option for adding a brim on the bottom of each part for better bed adhesion.

I'm not using any OpenSCAD libraries currently. I'd prefer the design to be as simple as possible to start. If any libraries are really beneficial for this task, I'm open to using them, but explain the reasoning first.

Hey there, I'm looking to create a customizable cable label, similar to the one I saw on Thingiverse. I'd like the OpenSCAD code to be fully parametric, allowing me to easily adjust dimensions and text.

Here's what I have in mind:

**Core Design:** The label should consist of two main parts: a curved "cable grip" section that wraps around the cable and a flat, rectangular label plate extending from it. The cable grip should be designed to accommodate different cable diameters. The label plate should have a raised, sunk, or through-hole text feature, depending on user choice.

**Parameters I'd like to control:**

*   `cablediam`: Diameter of the cable in millimeters.
*   `lablength`: Length of the rectangular label plate, measured from the edge of the cable grip in millimeters.
*   `labwidth`: Width of the rectangular label plate in millimeters.
*   `thickness`: Overall thickness of the label in millimeters.
*   `labeltext`: The text string to be displayed on the label.
*   `textfont`: The font to use for the text. (preferably Arial Black, but other choices should work too.)
*   `textappear`: An integer controlling the text appearance (0 for raised, 1 for sunk, 2 for through-hole).

**Modules I need:**

*   A module to create the outer rim that forms the label. This part creates the main shape, before cutting out the middle to create the cable grip and the label plate.
*   A module to make the flat, rectangular label plate.
*   A module to render the text on the label, and change its appearance based on the `textappear` parameter.
*   A `chull` module that will create the necessary shapes using the `hull` function.
*  A module that uses the chull module to create the curved cable grip.

**Key Features:**

*   The code should use `difference()` to cut out the cable hole and text and avoid unnecessary overlap.
*   I would like to use `linear_extrude()` to create the text.
*   I want a way to change text size as a factor of `labwidth`.
*  I would also like to use a `$fn` variable to control circle and cylinder smoothness.

Could you generate an OpenSCAD file based on this?  I'd really appreciate it!

[User] I need a parametric OpenSCAD design for a drone identification tag, similar to the example I saw. It should be a rectangular tag with engraved text on it, and the text should be configurable, as well as the overall length, width, and thickness. I also want the tag to have rounded corners, and I'd like to be able to adjust the radius of the rounding. Ideally, I'd also like a small mounting hole at each end. Can you help me with this? The text should be inset slightly so that it doesn't reach all the way to the bottom or the sides.

I'm looking to design a modular headphone/headset holder that can be customized for different desk thicknesses and headphone types. I'd like the design to be based on the idea of a main section that clamps onto the desk and then a separate holder part that attaches to that main section. Here's what I envision:

**Main Section:**

*   **Desk Clamp:** This part will be a basic shape that clamps onto the desk. It will consist of two horizontal platforms (top and bottom) connected by a vertical section.
    *   The bottom platform needs a length parameter.
    *   The top platform needs a separate length parameter, which should be shorter than the bottom platform.
    *   The distance between the top and bottom platforms needs to be adjustable based on the desk thickness. I’ll call this parameter `width`.
    *   There will also be a separate thickness parameter for both the top and bottom platforms.
    *   The vertical section connecting these platforms needs to have its own width parameter and this will form the base for the attachment mechanism.
*   **Attachment Mechanism Base:** I need the main section to also have a base on the edge for a holder part to attach. This base will be a small block with a mounting hole in the side.
    * This base should be attached to the vertical section of the desk clamp.
    * The base will need length, width, and height parameters.
    * The mounting hole should be a cylinder. It will need diameter, depth, and position (x, y, z relative to the main section base).

**Holder Part:**

*   **General Holder:** I need a general holder design to start with which is a small section that has a cylinder that slots into the mounting hole on the desk clamp base. Then another area to support the headphones.
   *   The base will be a cylinder that matches the mounting hole of the main section. This cylinder will need a diameter and depth parameter.
   *   The portion supporting the headphones will be connected to the base using a small transition block. I need that block to have its own height, width, and length.
   *   Finally the headphone holding portion will be a small block with rounded edges. This block needs its own length, width, and height parameters.

**Customization:**

*   I’d like the desk clamp's `width` parameter to be easily adjustable via the customizer, so I can set it to the thickness of my desk.
*   The lengths of the top and bottom platforms should be adjustable.
*   The lengths, widths, and height of all parts of the attachment base and headphone holder will need to be editable as well.
*   I want the mounting cylinder dimensions to be adjustable for different attachment types in the future.
*   I need to be able to change the size of the cylinder that extends from the base and attaches to the attachment base.

**Libraries:**

I'm not sure which libraries would be best here, but I assume something like BOSL2 or MCAD might be helpful for the screw holes/cylinder stuff, so feel free to use any library that will make the code easier to work with.

Could you provide me with the OpenSCAD files for the main section and a general holder section based on these parameters? I'd like to be able to customize all of those dimensions in the customizer.

I'd like to design a customizable phone or tablet stand using OpenSCAD. I've got some specific ideas in mind, and I'd like the design to be parametric, so I can easily tweak it for different devices.

Essentially, I want a stand that has a base and a tilted support. The device will rest against the support, which is angled backward. I need to be able to set the dimensions of the device, specifically its width, thickness, and height. The support will need to have an adjustable angle to get the right viewing tilt. It needs to have a tab or lip to keep the device from sliding off. I also want to be able to control how far up the height of the device the support extends, for better stability.

A cable hole needs to be included in the design. This would be a hole that goes through the support, close to the base, and it will route the charging cable of the device. This hole should have a customizable size and shape. Finally, the connections of the tilted support to the base should have some fillets to add strength and aesthetics.

Here are the parameters I'd like to control:

*   `Phablet_width`: The width of the phone/tablet.
*   `Phablet_thickness`: The thickness of the phone/tablet.
*   `Phablet_height`: The height of the phone/tablet.
*   `wall_thickness`: The thickness of the stand's material.
*  `support_angle`: The angle of the support (in degrees).
*  `support_hole`: Whether or not there's a hole for a cable in the support ("yes" or "no").
*  `support_hole_width`: The width of the cable hole in the support
*  `RatioFlying`: Ratio of flying support.
*   `Rc`: Radius of the charging cable hole in the base
*   `Rb`: Radius of the rounded joints.

I'm envisioning this being a single SCAD file, or perhaps a few if that makes more sense. I'm not using any libraries at the moment, but I'd be open to suggestions if you think it would simplify the code. I think this is fairly straightforward though so I don't think it's necessary.

I'd like to design a parametric dice using OpenSCAD. I'm aiming for something that lets me control the size, depth of the markings, and the roundness of the corners. I'd also like the option to choose whether the markings are holes or raised spheres. I'm imagining a 3D cube with rounded corners and markings representing a standard six-sided die pattern, where opposite faces add up to seven. I want all the faces and their respective markings to be generated using a loop or equivalent function.

Specifically, I'd like these parameters to be adjustable:

*   `size`: the overall size of the dice.
*   `depth`: the depth of the holes, or the height of the spheres, depending on the selected type.
*  `roundness`: the radius of the spherical rounding applied to the corners.
*   `marks`: a choice between "holes" and "spheres" for the type of marking on the faces.

The dice faces should adhere to the following pattern:
*   The +Z face should have the "1" pattern.
*   The -Z face should have the "6" pattern.
*   The +Y face should have the "5" pattern.
*   The -Y face should have the "2" pattern.
*   The +X face should have the "3" pattern.
*   The -X face should have the "4" pattern.

The die should also be oriented properly, so that these faces are in the correct standard orientation.

Could you generate the OpenSCAD code for this? I'm not using any external libraries.
