Okay, I'm looking to create a set of tools for making bias binding tape, similar to the functionality of the `bias_tool.scad` file I've been using, but with some improvements and a more modular design.

Essentially, I need a parametric OpenSCAD design that will generate a tool which folds a strip of fabric into bias tape. I'd like to be able to specify the following parameters:

*   **`binding_width`**: This is the width of the fabric before it's folded, which is also the final width of the bias tape when unfolded. I need it to range from at least 20mm to 170mm, just like in the example file.
*   **`tape_thick`**: The thickness of the folded fabric, plus a small clearance for movement, should have a minimum of 0.2mm to a max of 6mm with 0.2 steps.
*   **`form_length`**: The length of the section of the tool that gradually folds the fabric.  I need a range from 40 to 150mm.
*   **`stable_length`**:  The length of the straight section that stabilizes the folded tape after it comes out of the forming section. Range from 0 to 80mm is good.
*  **`gap`**: The gap between the two folded edges of the bias tape as they exit the tool, range 0.5 to 3mm with 0.2mm steps.
*  **`plunge_adjust`**: An adjustment, similar to what's in the original file, for the vertical position of the core. This will allow me to fine tune the initial position of the internal core to make sure the fabric path is correct. I'd like a range from -0.2mm to 3mm with 0.1mm steps.

I need to be able to control the smoothness of the internal curves, particularly the entry port. In the original file, this is done by `point_count`, `full_angle` and `core_rad`. It would be ideal if I could get an option to specify these, or at least have the code be well commented enough that I can tweak these values for my needs.

The original code uses `hull()` to create the core. I'd prefer it if the core were constructed using a different method that might give more flexibility in the future, perhaps a combination of `linear_extrude` and `rotate_extrude` (or `rotate` and `translate` on simpler shapes). Please do not use `hull()` for the primary geometry in the tool, but feel free to use `hull()` or `linear_extrude` for the text labelling.

The original code includes `access_hole()`, which acts both as a hole to push a needle through for threading and a steam escape. This should be kept but may need some adjusting, like the scale and position relative to the `form_length`.  I'd like an adjustable `hole_length` in addition to those parameters.

Also, the original code had a "Cutaway" view for visualizing the core, and I'd really appreciate that. Maybe this could be a boolean parameter instead of a string? Perhaps `show_cutaway` which defaults to `false`. We should use `color()` to show the core as yellow and red for the access hole. The main body of the tool can be grey to make it easy to print.

Finally, I'd like the tool to have a flat base for easy printing. The existing code has angled ends but this means it needs support when printing. Please ensure the tool sits flat on the print bed.

I think this will require a main scad file, and I do not need to use any external libraries. I'd like the main scad file to have all of the necessary comments to explain what every section of code does. Also, please include examples in a comment block of how to use the module to quickly create tools.

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

Okay, I'd like to create a set of parametric yut sticks, those Korean game pieces you toss. I have some specific ideas, and I'd like to be able to tweak things easily.

Here's what I'm thinking:

*   **Main Body Shape:** I want the sticks to be a sort of tapered, rounded shape, thicker in the center and thinner at the ends. I need to control the radius at the center and at the ends, and the overall length of the stick.
*   **Convexity:** I'd also like a parameter to control how "chubby" or "lean" the stick is, so it's not a straight taper. I saw that a "convexity" value works in the example. Something around 2 would be a normal shape, 3 would be very fat, and 1.x would make it closer to a triangular shape in cross section.
*   **Rounding:** The ends of the sticks should be rounded off with a bevel. I need to be able to control the radius of that rounded part.
*   **Text:** I want to be able to engrave text on both the flat and rounded sides of each stick. So one face will have Korean characters, the other some 'X' symbols. I need to control the text itself, font size, font, the depth, and a small "bolden" parameter to make the text thicker. I need to be able to specify the text depth and the font. I'd like it to also work with Korean characters.
*   **Symmetric/Asymmetric:** The sticks themselves need to be roughly semicircular, and I'd like a parameter to control how far into the round each goes (so they can go a bit more than half-round to 3/4 round.
*   **Fonts**: I will want to be able to chose between several installed system fonts

I guess what I'm aiming for is a single scad file that will allow me to tweak all those dimensions, the text, and the overall shape easily via customizer parameters. I also need to use minkowski and halfspace/halfplane functions to get this to work (I can't do it with simple subtractive geometry).

Okay, I've been playing around with this great OpenSCAD customizer file for spool drawers and a hanger, and I'd like to create something similar but completely from scratch. It's a bit involved, so bear with me.

The basic idea is a drawer system that attaches to the inside of a standard 3D printer filament spool. The design needs to be parametric, so I can adjust it to fit different sized spools. I envision three core pieces: a main drawer section, a hanger, and a cover. I'm thinking that I would want to use OpenSCAD for all the parts in a parametric way, as I think I might want to make further adjustments later on.

Here's a breakdown of the drawer design requirements:

*   **Drawer Body:**
    *   It should be a curved, hollow section that fits inside the spool's inner diameter.
    *   The depth of the drawer should be adjustable.
    *   The drawer should have a defined thickness for walls and bottom.
    *   The angle covered by the drawer should be a parameter so I can control how much of the spool it covers (e.g. full circle or a fraction of it).
    *   There should be options for internal dividers/sections, both radial and concentric, with their heights adjustable as a percentage of the drawer height. The number of these dividers/sections must be parametric.
    *   Asymmetric spacing of the sections should be possible.
    *   It should have a handle of some sort, with options for: nothing, a small protruding handle, or a hole for a finger or bolt.
*   **Attachment:**
    *   There needs to be a way to attach the drawers to the spool, likely with bolts. I need a parametrically defined hole diameter, with clearance.
    *   The position of these holes on the drawer should also be parametric so I can move them around based on the overall geometry.
*  **Labeling:**
    *   I want to be able to add printed text to the drawer, either raised or recessed, where both the text and font size are parametric.
    *   I would also like the option for a label holder area for a physical label, and its size/position should also be controlled by parameters.

The hanger design should:

*   Be a simple bracket that attaches to the underside of a surface like a table top.
*   Include a circular cutout or hole to hold the spool assembly.
*   Have parametric dimensions for mounting holes and thickness.

The cover design should:

*   Have a hole or way for a screw to be inserted to attach the cover to the spool and secure the spool on the hanger.

Here are the parameters I imagine controlling:

*   **General:**
    *   `PrinterNozzleWidth` (mm) - for wall thickness calculations
    *   `QualityMesh` (number) - for detail of curves
*   **Spool:**
    *   `SpoolInnerWidth` (mm)
    *   `SpoolOuterWidth` (mm)
*   **Drawer Body:**
    *   `PartHeight` (mm) - overall drawer height
    *   `PartRadiusCover` (degrees) - the angle covered by the drawer
    *   `PartClearance` (mm) - the space between the drawer and the spool
    *  `WallLayerCount` (number) - the number of nozzle widths to use for wall thickness
    *   `SectionLayerCount` (number) - the number of nozzle widths to use for section wall thickness
    *   `PartSection` (number) - the number of concentric sections
    *   `sectionHeight` (%) - height of the section as a percentage of drawer height
    *   `PartRadialSection` (number) - the number of radial sections
    *  `sectionRadialHeight` (%) - height of radial sections as a percentage of drawer height
    *   `PartAsymetric` (number) - the degree of asymmetry of the concentric dividers/sections
    *  `BottomThickness` (mm) - the thickness of the drawer bottom
*   **Handle:**
    *  `HandleType` (0:none, 1:handle, 2:hole)
    *   `HandleSize` (mm)
*   **Attachment:**
    *   `HoleScrew` (mm) - the diameter of the bolt hole
    *   `HoleLayerCount` (number) - the number of nozzle widths to use for the hole diameter clearance
*   **Label:**
    *   `PrintedLabel` (0:none, 1:raised, 2:recessed)
    *   `PrintedLabelText` (string or array of strings) - text to display
    *  `PrintedLabelSize` (mm) - the size of the printed text
    *   `LabelHolder` (0:no, 1:yes) - create a label holder?
    *   `LabelHolderHeight` (%)
    *  `LabelHolderWidth` (%)
    *   `LabelHolderClearance` (mm)
     *   `LabelLayerCount` (number) - the number of nozzle widths to use for the label thickness
    *   `LabelHolderSize` (mm)

*   **Hanger:**
    * `HangerThickness` (mm)
    * `HangerHoleDiameter` (mm)

*  **Cover:**
     * `CoverThickness` (mm)
     * `CoverHoleDiameter` (mm)

I'm imagining it would be best to structure the files to use separate modules for each section - like one module for the drawer body, one for the handle, one for the hole, etc.  This would make things easier to follow. It would probably make sense to have all these different pieces in a single file. I don't think I would need multiple files this time.

It sounds complicated, but it is just a parameterized set of shapes.

I'm looking to create a parametric design for a nut holder that fits into aluminum extrusion channels, like 8020. I want it to be customizable for different nut shapes, sizes, and the number of nuts it holds.

Here's what I need:

The holder should be a block shape, with a tapered edge for sliding into the extrusion. I need to control the following:

*   **Block Length:** The total length of the holder.
*   **Block Width:** The width of the wider side of the holder.
*   **Block Thickness:** The overall thickness of the block.
*   **Shoulder Thickness:** The thickness of the non-tapered part of the block, effectively the point where the taper starts.
*   **Screw Diameter:** The diameter of the clearance hole for screws that pass through the holder.
*   **Screw Count:** How many screws (and therefore nuts) the holder will accommodate.
*   **First Screw Distance:** Distance from the edge of the block to the center of the first screw hole.
*   **Screw Distance:** Spacing between the screw holes.
*   **Nut Trap Shape:** This should be selectable between "Square Nut", "Hex Nut", or "Round".
*   **Nut Trap Diameter:**  Diameter across the points (or flats) of the nut, for the nut trap cutout.
*  **Nut Trap Length:**  Height of the nut trap
*   **Washer Pocket Diameter:**  The diameter of the optional pocket for a washer.
*   **Washer Pocket Thickness:** Depth of the washer pocket.

I'd like the design to generate a single .scad file containing the fully parametric holder, incorporating the above parameters. I think it makes sense to make the nut traps and screw holes as cutouts from the block. The whole thing should be designed to print on a 3D printer.

Thanks for your help!

Okay, I'm looking to get a parametric spool designed for 3D printing, something I can use to organize things like solder, cables, and threads. I'd like it to be split into two pieces so I don't need supports, and they'll either press-fit or glue together.

Here's what I'm thinking about in terms of parameters:

**Spool Dimensions:**

*   **Flange Diameter:** This is the overall diameter of the circular ends of the spool.
*   **Inside Diameter:** The diameter of the hole in the center of the spool.
*   **Flange Thickness:** The thickness of the circular ends.
*   **Barrel Thickness:** The thickness of the material forming the central barrel of the spool.
*   **Traverse Length:** The length of the central barrel portion of the spool.
*   **Sides:** Control the number of sides in the "circle," allowing for different shapes (like hex or octagon) instead of a perfect circle if desired. It'd be good to set a minimum of 3 here so we don't have a zero sided shape, and this is used for all circles in the design.

**Connection Details:**

*   **Connector Length:** The length of the male connector portion of the design (and the corresponding depth for the female part).
*   **Connector Clearance:** A small clearance that can be used to either create a press fit or ensure a small space for glue.

**Output:**

*   **Part:** The output part, either "male", "female", or "both" so that I can print them separately or together. If set to "both", have it print the male part, then displace it and print the female part, instead of combining the two models onto the same print bed space.

**Additional Stuff**

*   **Model Displacement:** When printing both parts, this controls how far apart they are, so they don't merge.

I'd like the design to use the `linear_extrude` and `difference` functions, along with `circle`, and `translate`. Please can you generate the code using OpenSCAD. No specific libraries are needed, as I'd like to use only core OpenSCAD functions. The two parts should join together using a cylindrical connector, with the male side slotting inside the female side.

I'm looking to design a parametric magazine holder for a specific type of air rifle magazine, the Leshiy 2. I've got some measurements already, and I have a pretty good idea of the general design. I want a box that can hold multiple magazines, connected with hinges using a rod that runs through them, so that it folds open like a book.

Here's what I need it to do:

*   **Parametric Magazine Storage:** The design should be parametric for the number of magazines it holds. I'd like to be able to easily specify how many magazines the box will hold. It should default to holding three, but I'll need to be able to adjust that number.

*   **Magazine Dimensions:** The magazines are cylindrical, and will each need to fit in their own slot. The *major diameter* of the magazine is 36.2mm. There's a central *axis diameter* of 5.2mm, but the mags will sit on this. Each magazine has a *thickness* of 12.2mm. Taking the central axis into account, the total *thickness* we will need per-mag is 20.2mm

*   **Box Structure:** The box is essentially a rectangular prism with rounded corners, and it should hold all of the magazine slots. The walls of the box should have a *wall thickness* of 3mm. The box should have a small rounding radius on the corners. I think a radius of 1mm looks good.

*  **Hinges:** The box needs hinges on one edge that go all the way up the height of the box. The hinge should be designed to accept a rod that will run through them. These need to be designed parametrically based on the number of magazines in the design. These will need a tiny bit of tolerance, so we should introduce an offset parameter for the hinges so that they don't bind. I think an offset value of 0.1mm will work.

   The rod that will run through the hinges will have a given diameter that will need to be parametric. Let's set this to 4.1mm by default. The "binding" material around the rod needs to have a thickness of 1.7mm.

*   **Two halves:** The box is formed of two identical halves that connect via the hinges. One of the halves will have the hinge parts that *protrude*, the other will have the hinge parts that *receive* those protrusions.

*   **Specifics:** I'd like to use a resolution of 128, and set the rounding radius of the box to 1.

*   **Variables** Just to be clear, here are the variables you should be using in the design and their defaults:

    *   `mdiam = 36.2; // major diameter`
    *   `adiam = 5.2; // axis diameter`
    *   `mthk = 12.2; // magazine thickness`
    *   `tthk = 20.2; // thickness with central axis`
    *   `hnum = 3; // number of magazines for box to hold.`
    *   `wthk = 3; // wall thickness`
    *   `res = 128;`
    *   `r = 1; // rounding radius for box`
    *   `rj = 1.7; // thickness of material about binding axis`
    *   `rthk = 4.1; // opening rod thickness, set to cross-sectional diameter of whatever rod type you have available.`

I don't need it to be a *perfect* clone of the one I've described with code, but I want a similar outcome with all of these characteristics. And if it's not too much trouble, could you generate the code using only built in functions, rather than any libraries?

Could you generate the necessary .scad files to accomplish this? Thanks in advance!

I'd like a customizable tool holder design, something that I can 3D print, that will let me stick PVC pipe into it for holding tools. I envision a grid of these PVC pipe holders, and I'd like to be able to control the number of rows and columns, the diameter of the pipe that fits in the holder, the height of the holders themselves, as well as the thickness of the base and the walls surrounding the holders.

I'd like the OpenSCAD code to be fully parametric so that I can adjust all of these values. Also, I would like the code to subtract a cylinder from the base so that the PVC pipe fits snugly, but isn't flush with the bottom of the base. I expect a single .scad file to accomplish this task. I don't need anything more complicated; I don't anticipate having to use any of the libraries for this design.

toolStandGrid.scad:
```
/*[ Height ]*/
//Height of holders
holderHeight=30;

/* [ Number of rows ]*/
// Number of rows of holders
numRows=5;

/* [ Number of columns ]*/
// Number of columns of holders
numColumns=5;

/* [ Wall thickness ]*/
// Thickness of wall
wallThickness=4;

/* [ Base thickness ]*/
// Thickness of base

/* [ Holder diameter ]*/
// Inner diameter of tool holder
holderDiameter=48.26;  /* 1.5" PVC pipe */

/* [ Epsilon ]*/
// Millimeters to add to radius of holder
epsilon=.11;

holderRadius=holderDiameter / 2 + epsilon;

module makeGrid(height, radius) {
    for (row = [0 : numRows - 1]) {
        translate([0, row * holderRadius * 2, 0])
        for (column = [0 : numColumns - 1]) {
            translate([column*holderRadius * 2, 0, 0])
            cylinder(height, r = radius);
        }
    }
}

xOffset = (numColumns - 1) * holderRadius;
yOffset = (numRows - 1) * holderRadius;

translate([-xOffset, -yOffset, 0])
    difference() {
        $fn=360;
        makeGrid(baseThickness + holderHeight, holderRadius + wallThickness);
        translate([0,0,baseThickness]) makeGrid(holderHeight + epsilon, holderRadius);

I'm looking to create a customizable tool organizer based on a hexagonal lattice. I want to be able to specify how many rings of hexagons I want, and the diameter of the cylinders that form the tool holders themselves. These holders should all be the same length.

Ideally, there'd be a base plate at the bottom of these holders, and the whole thing should be designed such that I could optionally add a lazy susan base with integrated airsoft pellet bearings. I'd like to be able to turn on or off the lazy susan parts independently.

So basically, I need an OpenSCAD file that takes in parameters like:

*   **`holderHeight`**: The height of the tool holder cylinders.
*   **`numRings`**: The number of hexagonal rings in the lattice.
*   **`wallThickness`**:  The thickness of the walls of the cylinders.
*  **`baseThickness`**: Thickness of the base plate of the tool holder.
*   **`holderDiameter`**: The inner diameter of the tool holders.
*   **`pelletDiameter`**: The diameter of the airsoft pellets that will act as bearings.
*   **`showToolStand`**: A boolean to show or hide the tool holder part.
*   **`showSusanBottom`**: A boolean to show or hide the lower lazy susan base.
*  **`showSusanTop`**: A boolean to show or hide the upper lazy susan base.

The tool holder part should have a base plate that is a single solid piece and then the cylindrical tool holders should be placed on top of that base. The lazy susan should have a lower disc to act as the bottom support, as well as the upper disk with an integrated channel for the bearings, such that the upper disc can rotate on the lower one. The pellet diameter will determine the bearing race diameter, where the inner bearing race will be inset in the lower disk, and the outer bearing race will be an extruded circle on the top disc.

I'd like to see this generated as a single .scad file, if possible. I'm not using any specific libraries for this, so I don't need any library includes at the top of the code.

Hey, I'm looking to create a customizable luggage tag, and I'd love for you to help me design it in OpenSCAD. I want to be able to adjust quite a few things.

First, the overall dimensions of the tag should be adjustable - I need to be able to set the width and height of the main rectangle, as well as the base thickness and the overall tag thickness. I also want to control how rounded the corners are. There should be a slot for the strap that has an adjustable width and height, and I also need to be able to adjust the border thickness.

For the text, I need to be able to choose whether the text is raised or recessed. I'd also like a way to prevent the center of the letters from dropping out when using recessed text, which I think is a function of how deep the recess is, but maybe not for all letters. The font should be adjustable, as well as the font size, and I'd like to be able to choose the text for up to 5 lines of information. The text should be centered.

I'd also like to add an optional back text area for initials - I need to be able to change the text of the initials, their size, their font, and whether they're printed horizontally or vertically. It would be nice to move the back text left and right to center them too. It should be a separate cut so that it can be printed in a separate color. I'd also like the ability to select a honeycomb infill pattern for the back text. I need to control the thickness and diameter of the honeycomb infill and the depth.

The tag should also have an optional lid with an adjustable thickness. The lid should also have optional clips to hold it in place, and a tolerance option for PLA which would make the clips slightly wider apart to compensate for PLA not flexing as well as other materials. I also need a way to make a semi-circle cutout to assist in removing the cover. I'd also like to add the initials on the back of the lid - if I want them.

I think that's everything! I think this is a complex design, and I'm really excited to see what you come up with!

Hi! I'm looking for some help designing a parametric key safe in OpenSCAD. I have an existing design that I want to improve and make more flexible, and I'm hoping you can generate the necessary code.

Basically, I want a cylinder with a key-shaped cavity inside, and a hole on top for a numbered lock. The key cavity needs to have enough space to hold a standard house key, or similar. The overall design should be relatively robust and printable, with an emphasis on being easy to customize. The safe should have flat sides to make it more printable, and some text on the side to label what's inside. The text needs to be easily changed by the end user. Here are the basic requirements:

*   **Base Shape**: A cylinder, but flattened on two opposite sides.
*   **Key Cavity**: An internal cavity shaped to hold a key, including a small protruding section at the top.
*   **Lock Hole**: A hole on top, big enough for a standard combination lock like those I linked. (I included a specific link to the locks in the original design spec, but I don't expect the AI to be able to view that link, so it's enough that it's a standard combination lock).
*   **Text Label**:  Text on two opposite sides to label what the safe contains. The text should be mirrored on both sides. The text should be configurable by the user, as well as the font and font size.
*   **Parametric Design**: I'd like all relevant dimensions to be easily adjustable through variables in the OpenSCAD file (e.g. cylinder radius, height, cavity size, lock hole radius, text size, etc.).

I was thinking we might use some basic text extrusion, and possibly a rotation or two to get everything lined up. I'd like to generate the entire design from scratch, so I'm not looking to modify the existing code I provided (other than using it as inspiration for the new design). I do not need any external libraries for this project.

Can you help me create this?

        translate([0,-9.4,length/2]) cube(size=[10,10,length], center=true); // flatten the other side

I'd like to create a vase-like object with a mesh pattern suitable for use as a strainer, and I'd like it to be fully parametric. The mesh should be created from a series of triangle-like shapes that spiral around the vase, with gaps between them for drainage. I'd like to be able to specify the overall diameter and height of the vase, the spacing of the mesh triangles, the overhang distance of the triangle points, and the vertical and horizontal spacing between the triangle shapes. I want to print this in vase mode, so the design should be a single continuous wall. The bottom can be handled with infill, but I also want to be able to use the same mesh on the bottom if that makes sense. Also, try to keep the number of retractions at zero, if that is doable.

To be clear on the parameters, I need:
*   `Diameter`: The overall diameter of the vase.
*   `Height`: The overall height of the vase.
*   `Mesh_Spacing`: The vertical spacing between each layer of the triangle mesh.
*   `Mesh_Overhang`: The distance each point of the triangle over hangs the vase cylinder.
*  `Buffer_Height`: The vertical gap between triangle layers.
*   `Buffer_Width`: The horizontal gap between individual triangles within a layer.

I'm looking for a design where the triangle mesh continues around the vase and up, forming a spiral. The vase itself should be a simple cylinder with the mesh pattern applied to it. I'm fine with the bottom being a cylinder with less than 100% infill if that works better than trying to make a mesh bottom.

I don't have any specific libraries I need to use, so use whatever you think is appropriate.

Hey there, I'm looking to get some OpenSCAD files generated for a recessed lighting ring, sort of like the one I saw on Thingiverse, but I need a completely new design from scratch.

Basically, it's a ring that goes around a recessed light, like an LED retrofit or even an old can light. The main goal is to cover up the old hole or any gaps around the light fixture. I need it to be fully parametric, so I can adjust the dimensions easily in the Customizer.

Here are the key parameters I think I'll need:

*   `outer_dia`: The visible outer diameter of the ring, the part that covers the ceiling.
*   `recess_dia`: The diameter of the recess where the actual light sits. This needs to be slightly larger than the light itself.
*   `inner_cutout_dia`: The diameter of the hole that allows the back of the light to fit through; it needs to be bigger than the light's back side.
*   `inner_thick`: The thickness of the plastic *behind* the light itself.
*   `light_outer_thick`: The thickness of the ring at the outer edge of the light. This is where the ring meets the light face.
*   `ring_style`: This should be a dropdown menu with the options "flat_round" and "tapered".
*   `tapered_edge_thick`: If "tapered" is selected, this controls the thickness of the outer edge of the tapered section.

I'd like two modules, `taper_ring()` and `flat_ring()`, corresponding to the `ring_style`. I'd also like to generate the basic cylinder for each option using difference() to create the shape and cut the inner holes out of the larger main cylinder. The `taper_ring()` should use rotate_extrude() to create the sloped shape.

Please use the standard OpenSCAD library functions. I am not using any add-on libraries like BOSL or MCAD.

Could you generate the necessary SCAD files for this? Thanks a bunch!

I need to create a customizable Hirth joint that can be attached to the end of a rod or dowel. I've got some specific parameters in mind, and I want it to be designed as two separate parts: a "Pin" and a "Socket".

The basic idea is that the rod will insert into a cylindrical opening on one end of the joint, and the other end will have a Hirth joint profile. I'll be using the `hirth-joint.scad` library from the agentscad project for the Hirth joint itself. I need to control quite a few variables, and I would like to start by specifying all of those as customizer variables. Here is the list:

*   `nozzle`: This is for print compensation, and I'll start with 0.8 mm.
*   `wall_thickness`:  I'll start with 2.0 mm for the walls of the parts.
*   `joint_type`: This should be a string, either "Pin" or "Socket", determining the type of part generated.
*  `rod_diameter`: The diameter of the rod that inserts into the joint, start with 8.0 mm.
*   `rod_insert_depth`: How deep the rod goes into the joint, let's use 25.0 mm.
*   `joint_axis_diameter`: The diameter of the cylindrical part that extends from the Hirth joint, start with 9.0 mm.
*  `joint_screw_diameter`: The diameter of the screw hole for mounting, start with 3.3 mm.
*  `rod_screw_diameter`: The diameter of a screw hole for mounting that runs along the axis of the rod, defaults to 0, but I want it to be configurable.
*   `hirth_function`:  A string to select between "Sinus" or "Rectangle" Hirth profiles, defaults to "Rectangle"
*   `hirth_joint_r`: The radius of the Hirth joint, starts at 15.0 mm.
*   `hirth_nb_tooth`: The number of teeth in the Hirth joint, start at 10.0.
*   `hirth_tooth_h`: The height of the Hirth joint teeth, start with 5.0 mm.
*   `hirth_shoulder`:  The height of the shoulder below the Hirth teeth, start with 1.0 mm.

The design should generate both a "Pin" and a "Socket" version, but I'll choose which one to display via the `joint_type` variable. The "Pin" should have a solid cylindrical section extending from the Hirth joint, while the "Socket" should have a hole. It would be nice if the two parts could be displayed together for alignment, rotated and translated as in the example code.

I want the rod insert to have some clearance, so I want the rod opening diameter to be slightly bigger than the rod diameter. I used `rod_d = $rod_diameter + 0.3 + $nozzle / 2.0` in my example. The same principle should be used for the joint axis, with slightly larger diameter to allow for printing tolerances and screw diameters.

Could you generate the OpenSCAD code for me based on these parameters and constraints? I want it to be parametric, so I can adjust all of these variables through the customizer. I'm using the `hirth-joint.scad` library so you'll need to reference that.

[User]
I'm looking for some help designing a parametric OpenSCAD model for 3D printer Bowden tube clips. I've been using some I found online, but I'd like something more customizable. I'm aiming for a design that has a circular clip part with a tab that secures the tube.

Here's what I need to be able to adjust:
*   **Number of Clips:** I should be able to specify how many clips to render at once.
*   **Ring Thickness:** The thickness of the circular part of the clip.
*   **Ring Inner Diameter (ID):** The inner diameter of the clip where the Bowden tube goes.
*   **Ring Outer Diameter (OD):** The outer diameter of the circular clip.
*   **Ring Cut Width:** The width of the opening in the circle that lets you insert the tube.
*   **Tab Width:** The width of the vertical tab.
*   **Tab Height:** The height of the vertical tab.
*  **Tab Thickness:** The thickness of the vertical tab.
*   **Tab Offset:** The distance between the vertical tab and the ring.

I'd like the design to include a `bowden_clip_ring` module to create the circular part, a `bowden_clip_tab` module for the vertical tab, and a `bowden_clip` module that combines the ring and tab. Finally, a loop to render the specified number of clips in a row. I'm not using any libraries or anything like that and the `$fn` variable should be used to control the smoothness of circles and cylinders. A small `eps` variable could be used in the module definitions to avoid z-fighting.

For a quick example of what the parts look like, I can describe the .scad file I've already been using. This example version uses a single main scad file.
```
// 3D printer Bowden clip customizer.

// How many clips to print.
count = 6;
// Clip's thickness
ring_thickness = 1.42;
// Inner diameter of the clip
ring_id = 5.6;
// Outer diameter of the clip
ring_od = 8;
// Width of the clip's opening
ring_cut_width = 4.1;
// Width of the vertical tab.
tab_width = 4.6;
// Height of the vertical tab.
tab_height = 2.0;
// Thickness of the vertical tab.
tab_thickness = 1.9;
// Controls the distance between the vertical tab and the ring..
tab_offset = 1;

/* [Hidden] */

$fn = 64;
eps = 0.01;

module bowden_clip_tab() {
  ring_width = (ring_od - ring_id)/2;
  base_length = ring_width + tab_offset + tab_thickness;
  translate([-base_length-ring_id/2, -tab_width/2, 0])
    cube([base_length, tab_width, ring_thickness]);
  translate([-ring_od/2-tab_offset-tab_thickness, -tab_width/2, 0])
    cube([tab_thickness, tab_width, ring_thickness+tab_height]);

}

module bowden_clip_ring() {
  difference() {
    cylinder(d=ring_od, h=ring_thickness);
    translate([0, 0, -eps])
      cylinder(d=ring_id, h=ring_thickness+2*eps);
    translate([0, -ring_cut_width/2, -eps])
      cube([ring_od/2+eps, ring_cut_width, ring_thickness+2*eps]);
  }
}

module bowden_clip() {
  bowden_clip_ring();
  bowden_clip_tab();
}

for (i = [0 : count-1]) {
  translate([i*(ring_od + 3), 0, 0]) rotate([0, 0, -90]) bowden_clip();
}
```
Could you create an OpenSCAD file with this structure?
