I need a parametric OpenSCAD design for a holder that will house the control board for a VirtuaPin Digital Plunger. I've got the product link above. The holder should have two main parts: a base plate and a cover. The control board should snap into the base plate and then be enclosed by the cover.

The base plate needs to have screw holes for cable connectors along one side. These holes should be evenly spaced, and their position should be determined by the overall width of the holder. The board itself has a set of four mounting posts, which are the features that will snap into the holder. The base plate needs recesses to accommodate those posts.

The cover should attach to the base and completely enclose the board, but there need to be openings to allow cables to pass through. I think a few slots would work best. The cover also needs to mate to those four posts somehow, but it should just be an enclosure.

I need to be able to adjust the width and length of the holder via parameters, so I can customize it to fit my particular setup. Let's start with parameters for:

*   `width`: The width of the holder (in mm), which will also determine the spacing of the screw holes.
*   `length`: The length of the holder (in mm).

I'm going to want to control which part I'm rendering, so I'd like a string parameter `part` with three options: `"both"`, `"plate"`, and `"cover"`. If I select `"plate"`, only the plate is rendered. If I select `"cover"`, only the cover is rendered, and if I select `"both"`, both parts are rendered.

Please use the MCAD library as I've used that before and it's relatively easy for me to understand.

// Which part do you want to render?
part = "both"; // [both:Plate and Cover,plate:Plate Only,cover:Cover Only]

// width of the holder; wider means more screw holes for cable connectors (mm)
width = 183; // [90:250]

// length of the holder (mm)
length = 110; // [80:150]

Okay, I'm looking to generate some wooden toy train tracks, specifically ones that are compatible with either Brio or Lillabo brands, and I need a parametric OpenSCAD design to do this. I need to be able to specify the brand, the length of the track, the angle of the curve, and whether the track should have rails on one or both sides.

Here are the main requirements for the design:

*   **Brand:** Should have a parameter to select either "Brio-alike" or "Lillabo-alike." This will affect the dimensions of the rails and the connectors.
*   **Rails:**  I need an option to have rails on both sides of the track or just one.
*   **Track Length:** I need to specify the length of the final track.
*   **Track Angle:** I need to be able to define the angle of the curve for the track.  The track should be curved based on a circle, not just a simple bend.
*   **Connectors:** It needs male and female connectors on the ends of the track. The dimensions of these connectors will be dependent on the brand specified. The female connector has to be a cutout, not an added part, and the male connector should be on the "far" end of the curve. I need them to line up and fit together correctly when printed.

The design should be based on a 2D profile that is extruded along a curve and a similar profile for the connector pieces. This 2D profile should have rounded corners, as shown in the provided example. It looks like it uses `rounded_square` which needs a defined module or similar solution for rounding the edges.

I believe I'll need the design to define the following parameters:
`brand`, `rails_on_both_sides`, `final_track_length`, `track_angle`, `track_height`, `track_width`, `rounding`, `rail_height`, `rail_outer_limiter`, `rail_center_block`, `rail_inlet`, `male_plug_diameter`, `male_plug_length`, `male_plug_width`, `female_plug_diameter`, `female_plug_length`, and `female_plug_width` .

I'm not sure how to go about the calculation for the radius for the curved track so I'll leave that up to you, but it should be based on the final length and angle. I also am not sure how to use the `rotate_extrude` or `partial_rotate_extrude` modules and would need you to implement those as shown in the provided code.

male_plug_length = brand == 1 ? 175 : 170; //length from the rails end until the end of the round knob

female_plug_length = brand == 1 ? 180 : 175; //length from the rails end until the end of the round knob
female_plug_width = 75; // this value differs during different generations of brio

//Now it gets dirty: length and angle which is given by user, will be interpreted as part of a circle with defined radius

Hi, I'm looking to design a parametric dovetail guide for 3D printing, based on the design by David Barron. I've seen a version of this done in OpenSCAD, but I'd like to have a more flexible design I can tweak.

Specifically, I'd like the guide to be single-handed (either left or right) and have the option to change the dovetail ratio (like 1:6, 1:8, etc.). I also need to be able to specify the number and size of magnets for holding it in place. The base geometry should be a solid piece with a sloping face for the saw, and magnet recesses on the back.

Here are some more specific requirements for the design:

*   **Handedness:** Should be a parameter to choose either left or right hand.
*   **Dovetail Ratio:** A parameter to set the ratio (e.g., a ratio of 6 means a 1:6 dovetail angle).
*   **Magnets:**
    *   A parameter to set the number of magnets (e.g., 1 or 2).
    *   A parameter to set the magnet diameter and depth.
    *   Recessed magnet holes on the back of the guide.
    *   Spacing between magnets should be configurable.
    *   A slight tolerance around the magnet size for a good fit.
*   **Dimensions:**
    *   Overall width, height, and length should be configurable.
    *   A flat section for the square to rest on, with configurable size.
    *   Overall thickness of the guide should also be configurable.
*   **Labeling:** Should include a label to indicate the dovetail ratio on the face of the guide.
*   **Construction:** Uses hull() for smooth transitions.

I'd prefer if the OpenSCAD file(s) used as few extra libraries as possible. The design should be relatively simple and optimized for 3D printing.

Could you help me create this parametric OpenSCAD design? I don't have any code already, so it would all need to be from scratch.

Hey, I need an adapter for my airbrush. I've got a couple of different airbrushes with different thread sizes, and I'd like to be able to use them interchangeably.

Essentially, I need an adapter that goes from a G1/4 thread on one end to a G1/8 thread on the other. The design I have in mind is kind of like a stepped cylinder. The G1/4 thread should be on the bottom, with a section of 11mm diameter cylinder rising up from that. Then it transitions to a 15mm diameter cylinder, followed by a transition back down to 11mm, and then finally transitions down to 8mm diameter cylinder. Finally, the G1/8 thread comes at the top of this last section.  I need some flat surfaces between these sections to allow for gripping.

Here are the specific dimensions that worked for the 3d printed version that I'm basing it on, although I need a parametric design. Starting at the bottom:
- The G1/4 thread section should be 7mm long.
- Next, the 11mm diameter cylinder is 14mm high.
- Then, there's a transition up to 15mm diameter for 2mm, which creates the first flat surface.
- Next, a 15mm diameter cylinder of 4.5mm.
- Then there's the transition from 15mm back to 11mm over 2mm, which creates the second flat surface.
- Then, 8mm diameter cylinder of 4.5mm.
- Then, 4mm long G1/8 thread at the top.

I also need to make sure there's a hole going all the way through the adapter, so there should be a 4mm diameter hole running through the whole thing.

I'll need the OpenSCAD design to be parametric, so I can adjust the length of the different sections, thread lengths, cylinder diameters and the hole diameter, etc. I'd also like to be able to specify different thread types if I decide I need other sizes.

Can you generate the OpenSCAD code for me? I know this uses the `threadlib` library for the threads.

Hi, I'm looking for an OpenSCAD design for a flexible mount for quadcopter electronics. It should be able to attach to the standoffs on the flight controller stack and have a pouch to hold things like receivers or video transmitters.

Here are the key features I need, and please make it parametric so I can easily adjust things:

*   **Clasping Mechanism:** The mount needs to grab onto two standoffs using circular clasps. These clasps should have a defined gap, standoff bolt diameter, and surround thickness. The clasp design should also allow some flex, so the standoffs can be easily inserted.

*   **Pouch:** It should have a pouch in the middle to hold the electronics. I want to be able to specify the gap/height of this pouch, and also a length extension of the pouch if needed.

*   **Legs/Risers:** The mount should be able to have legs/risers, so that it can be raised above connectors or components on the flight controller. I want a parameter for the height of these risers and they should integrate smoothly with the rest of the design.

*   **Parameters:** I need parameters for:
    *   `pouch_gap`: The vertical gap for the pouch in mm.
    *   `standoff_bolt_diameter`: The diameter of the standoff bolts in mm.
    *   `standoff_surround_thickness`: The thickness of the material around the bolt hole in mm.
    *   `standoff_spacing`: The distance between the standoffs in mm.
    *   `riser_height`: The height of the risers in mm.
    *   `pouch_extension_length`: The length extension for the pouch in mm.

*   **Flexibility:** The design should ideally be flexible, so it can be 3D printed with TPU, and it should be a single print.

I'm thinking that I will need all of this within a single .scad file, it would be great if you could design that for me!

Hey, I'm looking to create a parametric calibration tool for lithophanes, something like a stepped wedge. I've seen a few designs out there, but I want to make my own version with some specific features.

Here’s what I’m thinking:

The core of the design is a grid of cells, each with a slightly different thickness. I need to be able to set the thinnest and thickest cell depths, as well as the height and width of each cell. There should also be a border around the grid, and I'd like to control its thickness.

It should include labels on the sides of the model, one for the depth of the cells (in mm), and another for the incremental cell change.

And I'd also like to include up to 3 lines of text, each independently configurable for the actual text, placement on the model (front, top, bottom, left or right), horizontal and vertical alignment, and font size. The cell grid should be cut out such that it does not interfere with the labels on the top, bottom, and sides of the calibration piece, but _does_ cut the text if placed on the front.

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

*   **Grid:**
    *   `borderT`: Border thickness (in mm)
    *   `cellDepth1`: Thinnest cell depth (in mm)
    *   `cellDepth2`: Thickest cell depth (in mm)
    *   `cellH`: Cell height (in mm)
    *   `cellW`: Cell width (in mm)
*   **Labels:**
    *   `CRTextSize`: Text size for column/row labels
	*	`columnTextAlignH`: Horizontal alignment for column labels (mm)
	*	`columnTextAlignV`: Vertical alignment for column labels (mm)
	*	`rowTextAlignH`: Horizontal alignment for row labels (mm)
	*	`rowTextAlignV`: Vertical alignment for row labels (mm)
*   **Text 1-3:**
    *   `text1`, `text2`, `text3`: Text string
    *   `text1AlignH`, `text2AlignH`, `text3AlignH`: Horizontal text alignment (mm)
    *   `text1AlignV`, `text2AlignV`, `text3AlignV`: Vertical text alignment (mm)
    *   `text1Size`, `text2Size`, `text3Size`: Text size
    *   `text1Location`, `text2Location`, `text3Location`: Text placement (options: "None", "Front", "Top", "Bottom", "Left", "Right")

I’d also appreciate it if the model calculated things like grid width and height automatically based on the number of cells and specified cell size and borders, so that I don't have to figure that out myself each time I want to generate a model with different cell depths. And the text should all be cut into the model.

Could you generate a set of OpenSCAD files for this? I’m not particular on libraries, but if there are commonly used OpenSCAD libraries that would be useful, please do use them. Also, please do not assume a particular naming convention (e.g. the user can decide if the files should have `_v1`, `_v2` suffixes). Thanks!

Hi there! I'm looking for an OpenSCAD design for a tweezer holder, but I need it to be highly customizable. I've seen a few designs out there, but none quite fit the bill. I'd like to be able to control pretty much every aspect of the design.

Specifically, I need a holder that can accommodate a variable number of tweezers, each of which can have its own width and depth. The overall design consists of a backing plate, dividers, supports, and a base housing to hold the tweezers in place. It also needs a top guide to keep the tweezers aligned.

Here are the parameters I need to control:

*   **`tweezer_widths`**: A list of values, where each value defines the width of a tweezer slot. There will be a slight clearance added to these.
*   **`tweezer_depths`**: A list of values to define the depth of the tweezer slot. The last element is used for the remaining tweezers when there are more widths specified than depths. This list should allow individual setting of depth for each tweezer, similar to the setting for widths.
*   **`tweezer_height`**: The total height of the tweezer guide.
*   **`back_thickness`**: The thickness of the backing plate and the front of the housing.
*   **`separator_width`**: The width of the spaces between each tweezer slot.
*   **`separator_thickness`**: The thickness of the dividers between the tweezer slots.
*   **`bottom_height`**: The height of the plate that prevents the tweezer from falling downwards out of the housing.
*   **`top_height`**: The height of the top guide.
*   **`house_height`**: The height of the bottom housing for the tweezers. Higher values create a stronger hold.
*   **`house_thickness`**: The thickness of the tweezer at the bottom, where it is housed. Clearance is added to this.
*   **`middle_support`**: The width of the middle supports used when the holder is not fixed to a backing.
*  **`top_mask`**: The height of the backing part at the top.
*  **`bottom_mask`**: The height of the backing part at the bottom.
*   **`clearance`**: A global clearance value that should be added to several dimensions, like the tweezer widths and the house thickness.

So, I need to be able to adjust all those things. I'd like the design to be generated as an OpenSCAD file, or if it's better split into multiple files. This will allow me to experiment with different settings and tweak the design to my exact needs. I don't need to use any external libraries.

Thanks in advance!

Okay, I've been playing around with this OpenSCAD script for generating 2D formicarium layouts, and I think it would be amazing if it was more customizable and robust. It's currently just flat, but I'd love to take it to a 3D level.

Basically, I need a parametric OpenSCAD design for creating formicarium modules that I can then combine and connect to make larger, more complex setups. Here's the breakdown:

**Core Functionality:**

1.  **Grid-based Layout:** The design should be based on a grid of cells, similar to the current script. I'd like to be able to define the grid size using `GRID_X` and `GRID_Y` parameters (like the current example), and probably `CELL_SIZE` to specify the dimensions of an individual cell.

2.  **Procedural Maze Generation:** I need the system to generate a maze-like network of tunnels within this grid. The current system does this using a random seed, and I'd like that maintained - `SEED` parameter (0 for random generation), should be available. The maze should always be a single connected path with no isolated 'islands'. The original implementation's constraint to having only a single connected path is very important - I don't want any islands.

3.  **Entrance:** An entrance point to the maze, which can be positioned at any cell. It should be customizable using an `ENTRANCE` parameter (which should be an `[x, y]` list) like the existing design, defaulting to the center of the grid if not specified.

4.  **Room Tiles:** Some of the maze cells should be "room" tiles, wider than the tunnels and meant to be areas of nest space. The current system has a decent system for this (although the output is 2D for now); it uses a `find_rooms` function.

5.  **3D Extrusion:**  I'd like to take this design into 3D. This involves extruding the maze and room tiles to a specified height - so `CELL_HEIGHT` would be necessary. Also, the tunnels need to be tunnels, so the extrusion should only be an outline of the square shape for the tunnels. The "rooms" should be solid.

6.  **Customizable Tunnel Width:** The width of the tunnels should be adjustable. So that could be `TUNNEL_WIDTH` as an adjustable parameter.

7.  **Customizable Room Size:**  Rooms should have customizable size - ideally this is relative to the cell size using a `ROOM_SIZE_FACTOR` parameter.

8.  **Connection Points:** I need a way to connect these modules together. This means I need connection points on the edges of each module. These could be simple pegs and holes, or some other way of joining. I think pegs and holes will do it for me. I'll need parameters for this too. Like, `PEG_RADIUS`, `PEG_HEIGHT`, `HOLE_RADIUS`, and a `PEG_OFFSET` to define where these connection points are located relative to the corners of the module. I think the connection points should be in the middle of each edge, and should be extruded from the bottom of the base.

9.  **Base:** Each module should have a base of a specific thickness for stability that supports all parts of the module, and have space for the connector pins. I'll probably want this to be a parameter too, maybe `BASE_THICKNESS`. I'd also need a `BASE_OFFSET`, since all other objects are relative to the top surface of the base.

10. **Feature placement:** I'd like to be able to add some simple 3d structures to the generated rooms. So, for instance, some small cylinder to represent a water source. The location of these should probably be defined by a list of locations in each room, relative to the center of the room, and should also allow parameters to configure the size of each structure - `FEATURE_LOCATIONS`, `FEATURE_RADIUS`, `FEATURE_HEIGHT`.

**Parameters:**

Here's a summary of the parameters I'm thinking I'd need:

*   `GRID_X` (int): Number of cells along the X-axis.
*   `GRID_Y` (int): Number of cells along the Y-axis.
*   `CELL_SIZE` (float): Size of a single cell (square side length).
*   `CELL_HEIGHT` (float): Height of the extruded cells/tunnels.
*    `TUNNEL_WIDTH` (float): Width of the tunnels
*   `SEED` (int): Seed for random maze generation (0 for random).
*   `ENTRANCE` (list of int, `[x,y]`):  Position of the maze entrance.
*   `ROOM_SIZE_FACTOR` (float):  Multiplier on cell size for the "room" areas.
*   `PEG_RADIUS` (float): Radius of the connection pegs.
*   `PEG_HEIGHT` (float): Height of the connection pegs.
*   `HOLE_RADIUS` (float): Radius of the connection holes.
*   `PEG_OFFSET` (float): Distance of the pegs and holes from the edges of the module.
*   `BASE_THICKNESS` (float): Thickness of the base for each module.
*   `BASE_OFFSET` (float): How far the generated base will sit relative to the tunnels.
*   `FEATURE_LOCATIONS` (list of list of floats, `[[x1,y1],[x2,y2], ...]`): Locations for 3d features inside rooms, relative to the center of the room.
*   `FEATURE_RADIUS` (float): Radius of 3d features.
*    `FEATURE_HEIGHT` (float): Height of 3d features.

**Libraries:**

I don't think I'm using any particular libraries here, but if you are using any be sure to let me know and which library they're from. I'd prefer to avoid using libraries if it is possible, though.

Could you design a module in OpenSCAD that can do all of that, and include the necessary parameterisation so I can generate all sorts of formicaria? I don't think I need any help with assembling them myself, I just want to focus on generating the module. I'm particularly interested in seeing how the random generation works in 3D. Thanks!

I'm looking for a way to generate stackable storage containers for my RPG dice and miniatures, and I'd like it to be customizable. I've been using this other OpenSCAD file that does most of what I want, but it's a bit clunky and I'm hoping you can build something better from the ground up.

Specifically, I need three types of containers: one for dice, one for miniatures, and a lid that can fit either. The dice container needs to have individual slots for a standard 7-piece polyhedral set (d4, d6, d8, d10, d%, d12, and d20). The miniature container should be taller and have one large slot to fit a 25mm based miniature. The lid should have an option for a flat top, or an optional recessed area that will fit a logo or text.

I would like the following design parameters to be configurable:

*   **Render Object**: a variable to select which object to render - "die", "figure", or "lid"
*   **Lid Design**: when rendering the lid, a variable to specify a pre-set logo, custom text, or no design.
*   **Lid Text**: a string to be used if the "Lid Design" option is set to custom text
*   **Lid Font**: the font to be used for custom text
*   **Lid Text Scale**: a scaling factor to make the text fit the lid properly
*   **Logo Depth**:  how deep to engrave the lid logo
*   **Die Inner Radius**: the inner radius of the die slots
*   **Die Pocket Height**: the height of the die storage slots
*   **Figure Pocket Height**: the height of the miniature storage slot
*   **Wall Thickness**: the thickness of the container walls
*   **Connector Height**: the height of the interlocking connector
*   **Connector Width (Top)**: the width of the connector at its top
*   **Connector Width (Bottom)**: the width of the connector at its base
*   **Connector Gap Offset**: a small offset for an easier fit when clipping
*   **Connector Degrees**: the angle of the interlocking tongue/groove, in degrees
*   **Connector Count**:  the number of interlocking connectors (2, 3, or 6)
*  **Shell Style**: The general shape of the shell. Options should include "rounded", "cylinder", and "secant".
*   **Shell Expansion**: for rounded shells, how much the shell expands
*  **Shell Grip Count**: the number of grip gaps
*  **Shell Grip Ratio**: how much the groove should be widened relative to shell expansion
*  **Grip Style**: "vertical" or "helical" grip pattern for the outer shell
*  **Grip Helix Offset**: how much the helical grooves should be slanted, related to the Shell Grip Count
* **Magnet Radius**: Radius of the magnets
* **Magnet Height**: Height of the magnets

The containers should connect using a twist-lock mechanism. I'm thinking a tongue-and-groove type connector, like a bayonet mount, would work well. It'd be nice if the base of the die tray and the lid could accept magnets as well, maybe three per section?

I'd like the containers to have a rounded outer shell with grips for easier handling, but I'd also like options for cylindrical and secant shell styles. The grips should be configurable. Maybe something like vertical or helical cutouts?

Could you generate the OpenSCAD files for me? I do not need you to include code for any logo SVGs or fonts; I'll bring my own.

Hey, I'm looking to get a set of customizable vise jaw covers designed in OpenSCAD. I've got some pretty specific needs and I think I need a parametric design to handle it.

I need to be able to specify the width and height of the vise jaw itself, and the thickness of the material I want to use for the covers. So, those should be parameters, like `wvise`, `hvise`, and `tmat`.

Then, I'd like to have some options for grooves on the cover. First, I want to specify a width for a horizontal groove, `hwgroove`. This should default to 0 if there is no groove desired. I also want to be able to set a width for vertical grooves, `vwgroove`, which also should default to 0 if I don't want them. If there are vertical grooves I also want to be able to specify how many to create, `nvgro`.

Finally, I would like the option to include magnets in the design to hold the covers in place. I need a switch, `mshape` that lets me select either no magnets (0), rectangular magnets (1), or round magnets (2). If I use magnets I need to specify the magnet's width, length (only for rectangle), and thickness (`wmagnet`, `lmagnet`, `tmagnet`). The magnet should sit flush on the surface (or very slightly recessed) so the parameters should be used to size the cutouts properly.

The final design should use `difference()` to cut out the vise jaw shape from the cover, as well as any grooves and magnet holes. And please make sure the grooves are calculated properly with a 45 degree rotation of a cube shape, like they do in the example code I attached. Also the magnets should be positioned on the corners of the vice with the magnet holes being created by using the magnet module.

So that's it I think! I'm happy to answer any questions you might have.

I need an OpenSCAD design for a customizable lid, and I want it to be parametric. Here's what I'm looking for:

**Lid Types:**

*   **Internal Lid:** This lid fits *inside* the container.
*   **External Lid:** This lid fits *over* the container.

**Lid Parts:**

*   I need the option to generate the full lid *with* the knob.
*   I need the option to generate just the lid.
*   I need the option to generate just the knob.

**Lid Shapes:**

*   **Flat:** Just a simple flat disk.
*   **Flat with Rim:** A flat disk with a raised rim around the edge.
*   **Flat with Overhanging:** A flat disk with a small overhanging lip around the edge.
*   **Pan:** A flat disk with a curved vertical offset at the edge.
*   **Pan with Overhanging:** A 'Pan' shape with an additional overhanging lip.

**Parameters:**

Here are the parameters I need to be able to control.  I'm including example values in brackets as a guide.  I want all of these to be adjustable variables at the top of the file.

*   **General:**
    *   `$fn` (smoothness): \[96]
    *   `type`: \[1 or 2]  (1=internal, 2=external)
    *   `part`: \[0, 1, or 2] (0=lid & knob, 1=lid, 2=knob)
    *   `shape`: \[1, 2, 3, 4, or 5] (1=flat, 2=flat with rim, 3=flat with overhanging, 4=pan, 5=pan with overhanging)
*   **Lid:**
    *   `lid_id`: Inner diameter of the lid \[194.6]
    *   `lid_od`: Outer diameter of the lid \[200]
    *   `lid_thi`: Thickness of the lid \[1.8]
    *   `rim_hi`: Height of the rim \[7.8]
    *   `rim_thi`: Thickness of the rim \[1.9]
    *   `overhang_wid`: Width of the overhanging lip \[4.0]
    *   `overhang_thi`: Thickness of the overhanging lip \[1.6]
    *   `v_offset`: Vertical offset of the "pan" shape \[10]
*   **Knob:**
    *   `knop_base_dia`: Diameter of the knob's base \[20]
    *   `knop_top_dia`: Diameter of the knob's top \[30]
    *   `knop_hi`: Height of the knob \[22]
    *   `knop_chamfer`: Chamfer of the knob \[3]

I think I'd also like to include these parameters even though they're less visible and shouldn't be considered for "easy" customization.
    *   `knop_thread_dia`: Diameter of the knob's thread \[8]
    *   `knop_thread_len`: Length of the knob's thread \[10]
    *   `knop_nut_thi`: Thickness of the knob's nut \[4.8]

**Additional details**
The model should use these .stl files: "BNM7T67L10.stl" and "BNM7N67T30.stl".  These will be used for the threaded portion of the knob.  Please make sure they are imported and used properly. They are for an M7 thread, and I need these parts to be included by default when the knob is generated. I would like for the stl files to be imported rather than designed in OpenSCAD.

I'm not using any libraries in the current version.  I'd like the code to be as self-contained as possible.

Please provide me with the OpenSCAD file(s) that generate the lid and knob based on the given parameters. I'd prefer just one file if possible.

I'm looking to create a lithophane calibration tool, and I've seen some great ones out there, but I want something that's highly customizable. I'd like to design it in OpenSCAD, and I was hoping you could help me generate the code.

Essentially, I want a square grid of cells, each with a different thickness, that can be used to test the optimal thickness for making lithophanes. The tool should have these basic features:

1.  **A square grid:** Each cell in the grid will have a slightly different thickness. Let's start with a 10x1 grid - so ten cells in a row, not a full grid.
2.  **Base thickness:** The entire thing will have a base thickness for stability, and this should be adjustable.
3.  **Variable cell thickness:** Each of the ten cells should increase in thickness by a set amount. The minimum thickness of the first cell should also be adjustable, so we can go from 0.5mm to 1.4mm or 1mm to 1.9mm etc.
4. **Cell width** The width of each cell should also be adjustable, so we can make them wider or narrower.
5. **Borders** Each cell and the entire grid should have a border surrounding it. This border thickness should be customizable.
6.  **Labels:** Each cell should have a label indicating its specific thickness. These labels should be centered on a small tab above each column, and their alignment should be adjustable, and the size of the text should also be adjustable.
7.  **Title:** The tool should also have a title tab at the top with some customizable text (like "Material", "Printer name", etc.) The text size, horizontal and vertical alignment should be customizable.

I think that's everything! Oh, and if it's not too much trouble, can you add a little output so that the user can see the dimensions of the model and the range of thicknesses? That's something that I've found really helpful in other models.

I don't need any specific libraries for this right now, just pure OpenSCAD.

Thanks so much!

I'm looking to create a customizable coin generator in OpenSCAD. I'd like it to have a few key features that I can control:

First, the coin itself should be a circular disk. I need to be able to set the diameter of the coin. It should also have a raised border around the edge, and I'd like to be able to adjust both the width of that border as well as its height. So three parameters here: `coin_diameter`, `coin_border_width`, and `coin_border_height`. The base disk's thickness should be a separate parameter too - `coin_base_height`.

Next, I want to be able to engrave an emoji in the center of the coin. It needs to be configurable, so I'll need to be able to specify either an emoji character directly (like "🦄"), or the unicode number that corresponds to it. It'll also need parameters to set the font, the size of the emoji, and the depth of the engraving. I want to control the font via a string, so it should support font files that are installed on my computer, like "Segoe UI Emoji". So that's four more parameters: `emoji_char`, `emoji_number`, `emoji_size`, `emoji_font`, and `emoji_depth`.

Finally, I want to add the option for decorative spikes around the outer edge of the coin. This should be optional with a configurable number of spikes and the height of the spikes controlled via a multiplier of the `coin_diameter`. These should also be raised, not engraved. I also want the height of the spikes to match that of the coin border. So, lets say parameters: `num_spikes`, `spike_size_mult`, and `spike_height_offset` - the offset is because they should be at the same height as the `coin_border_height`.

I think that covers all the customizable elements. I don't have any specific requirements for libraries but do want to ensure the code is well-structured and readable. So, could you please generate an OpenSCAD file that handles all of this?

I'd like to design a spice rack that uses wooden sticks as supports. I've got some ideas about how it should work and some specific parameters I'd like to be able to control.

The rack will be made of a back piece with a couple of mounting surfaces and then the stick supports that come out from it. I'll be using standard wooden dowels so I need to account for that when creating the supports.

First, I'd like to control the overall dimensions of the back piece, including the width, height, and thickness. I also need to specify the thickness of the joiners that will hold the sticks and the radius of the wooden sticks I'm using. Let's also allow for some "quality" settings so the model renders quickly for adjustments or slowly and precisely for printing.

The placement of the wooden sticks needs to be adjustable, so I'll need to be able to control the horizontal and vertical positions of the top, middle, and bottom stick supports. These should be controlled as percentages of the overall back piece's width and height, so that everything scales nicely.

For mounting the rack, I need to define the size of mounting tape surfaces on the left and right. These can have adjustable widths and a height that's a percentage of the overall back piece height and its own thickness.

Finally, I'd like an option for a hook on one of the stick support locations, that is adjustable for its height, start angle, thickness, curve angle, curve radius, and sphere point radius.

So to summarize, I need a parametric design where I can adjust the following:
*   **Model Properties:**
    *   `q`: Quality setting (0 for fast, 1 for fancy) which impacts `$fn` and `fst`.
    *   `w`: Width of the back piece
    *   `h`: Height of the back piece
    *   `t`: Thickness of the back piece
    *  `st`: Thickness of the stick joiner
*   **Stick Properties:**
    *   `sr`: Radius of the wooden sticks
    *   `tx`: Top stick x position (% of width)
    *   `ty`: Top stick y position (% of height)
    *   `mx`: Middle stick x position (% of width)
    *   `my`: Middle stick y position (% of height)
    *   `bx`: Bottom stick x position (% of width)
    *   `by`: Bottom stick y position (% of height)
*   **Adhesive Mount Properties:**
    *   `fl`: Left mounting tape width (0 to disable)
    *   `fr`: Right mounting tape width (0 to disable)
    *   `fh`: Mounting tape height (% of back piece height)
    *   `ft`: Mounting tape thickness
*   **Hook Properties:**
    *   `hook`: Enable/disable hook (0 or 1)
    *   `hh`: Hook height
    *   `hs`: Hook start angle
    *   `ht`: Hook thickness
    *   `hc`: Hook curve angle
    *   `hr`: Hook curve radius
    *   `hpr`: Hook sphere point radius

The file should be designed using OpenSCAD, including the use of the minkowski operation, and a custom `fillet` module, and should output a single solid. Please use functions to compute the stick support coordinates (`p0x`, `p0y`, `p1x`, `p1y`, `p2x`, `p2y`, `p3x`, `p3y`, `p4x`, `p4y`) rather than having them be global variables, and also use functions to compute the internal values such as `srt`, `rh` and `rw`.
