Okay, I'd like to design a customizable hexaflexagon that displays a three-word message, similar to the provided example but with a few more parameters for customization.

Here's what I'm looking for:

**Overall Structure:**

*   The design should be based on a hexagonal arrangement of triangles that can be folded to reveal different faces, each with a word.
*   The core structure is based around a series of triangular panels, connected by hinges. It should function as a flexagon.
*   It should leverage the MCAD library, specifically the `fonts.scad` module, to handle text display.
*   The design should allow for 3 words, with each word being on one face of the hexaflexagon.

**Customization Parameters (I'd like these to be editable parameters at the top of the file):**

*   **Words:**
    *   `word1`: String, the word to display on the first face (max 6 letters).
    *   `word2`: String, the word to display on the second face (max 6 letters).
    *   `word3`: String, the word to display on the third face (max 6 letters).
*   **Triangle Dimensions:**
    *   `tri_length`: Number, the length of the edges of the triangles.
    *   `tri_height`: Number, the height of the triangles (also the radius of the hinge cylinders).
*   **Hinge Tolerance:**
    *   `tolerance`: Number, the tolerance between hinge parts for fit.
*   **Font Scaling:**
    *   `font_scale`: Number, this parameter should scale the font size relative to the triangle length
*   **File output:**
  *    I want it to produce two parts that can be printed on a 3d printer.
  *   There should be enough space to remove the support structures that will be generated.
  *   I need it to be easy to print without supports after the initial print

**Specific Design Elements (Keep these generally the same as the example):**

*   **Triangles:**  Each face of the hexaflexagon is composed of six triangles connected by hinges.
*   **Hinges:**  Hinge pins should be designed with a cylindrical shape and proper tolerances for smooth folding.
*   **Linkage:** There should be link pieces to connect the hinge portions
*   **Text:** Words should be embossed/engraved onto the faces. They should be displayed centrally on the triangle, scaling to fit if necessary

**Functionality:**

*   The hexaflexagon should be able to fold and reveal each of the three words.

**Things to Note (Again, based on the example):**

*   I'm expecting the output to be printable without additional support structures after the first print.
*   I expect that if i use a space in the word that it will result in a bad experience.
*   I'm using the 8-bit polyfont from `fonts.scad`.
*   I expect a single .scad output file, no other files are needed.
*   I expect all library functions to be called using the `<>` syntax.
*   The words should be displayed without a visible backing material behind the words

I think that covers everything. Please provide the OpenSCAD code when you can.

Okay, I'd like to design a customizable board game card holder with a label, but I'd like a completely parametric design. I've already got the basic functionality figured out in the provided code, but I want to make it more robust and flexible with the following changes.

Here's what I'm looking for:

**Core Functionality (Keep these):**

*   **Card Storage:** The design needs to store a stack of cards of a specified length, width, and height.
*   **Locking Mechanism:** I like the lock and key mechanism for stacking holders and lids. It should remain similar.
*   **Customizable Label:** The ability to add text to the side of the holder, either engraved or printed, using various fonts is necessary. The location of this label needs to be parameterizable.
*   **Multiple Holders/Lids:** The code should allow for printing multiple holders and lids with a configurable spacing between them.

**Requested Enhancements and Parametrization:**

1.  **Overall Dimensions:**
    *   `cardX`, `cardY`, and `cardStackZ` should remain, controlling the internal card dimensions.
    *   I'd like to add `holderWallThickness` as a single parameter to control the thickness of *all* walls (long, short, and bottom). This simplifies things and makes changing the overall robustness easier. It should replace `longWallStrength`, `shortWallStrength`, and `bottomWallStrength`.
    *   I want to introduce `holderOverallX` and `holderOverallY` that control the overall external x and y dimensions of the main holder body. The internal dimensions based on cardX and cardY should adjust based on these and `holderWallThickness`, such that changing one does not break the others. This would allow the user to make a wider case without changing the card dimensions, for example. `holderOverallZ` would remain the same as `holderZ` (the key, the base, and the locks).
    *   Additionally, add `lidOverallX` and `lidOverallY` to control overall dimensions for the lid and its grip. The main key and grip dimensions should adjust to make sure the parts fit as described previously and according to the new overall dimensions.

2.  **Locking Mechanism:**
    *   `lowerLockY`, `lowerLockZ`, `upperLockY`, `upperLockZ`, `keyRailZLid`, `keyRailZBody`, `stopBitStrength`, `lockNubRadius` and `lockNubDistanceToCorner` should remain as direct parameters.
    *   I would like to add `lockFudgeFactor` to the locking mechanism specifically. This factor should not affect the space around the cards (which should be controlled by `spaceAroundCard`). This factor should affect the x, y, and z dimensions of the locking mechanism only.
    *   I would like a parameter `keyRailOffset` that controls the x position of the key rail in relation to the body edge.

3.  **Card Spacing:**
    *   The `spaceAroundCard` parameter should remain to control the spacing between the cards and the inside walls.

4.  **Lid Customization:**
    *   The `lidGripStrength` should remain.
    *   I would like `lidHoleRadius` to be based on a percent of `cardX` rather than being based on a series of other parameters. This would make it simpler to adjust the lid size. This should become `lidHolePercent`.

5.  **Label Customization:**
    *   The `label`, `font` and `style` parameters should remain.
    *   Introduce a `labelOffsetX` and `labelOffsetY`, and `labelOffsetZ` parameter so I can change the text position along the x,y, and z-axis, in addition to left or right sides.

6.  **Printing and Assembly:**
    *   The `printDistance` parameter should remain to control the spacing between printed items.
    *   I no longer need the `release` parameter from the original code.

7.  **Parameter Naming and Organization:** Please group related parameters for better organization in the customizer (e.g., Card Dimensions, Holder Dimensions, Lock Dimensions, Lid Dimensions, Label Customization, Printing Settings).

8.  **General Clean-up:** Please rename variables and modules to be more descriptive when it makes sense.

**Libraries:**

*   Please use the `Write.scad` library from the original code.

**Output:**

The code should output the holder and lids as separate objects as before. I would like all parameters to be modifiable via the OpenSCAD customizer.

Can you provide me with the OpenSCAD code for this?

Okay, I'm looking to generate a bunch of crystal-like shapes, and I have some very specific control over how they're arranged and shaped. I'd like a parametric OpenSCAD file that lets me adjust these features easily.

First, the overall concept is to have a central spherical "base" with crystal shapes radiating outwards from its surface. The crystals are not all the same height and are distributed in a circular pattern that gives the illusion of the crystals growing outwards. Think of a bouquet.

Here are the specific parameters I want to be able to control:

*   **`seed`**:  An integer that will control the random placement of the crystals. Changing this should change the arrangement while keeping the same number of crystals and overall shape.
*   **`num`**: An integer representing the number of crystals to generate.
*   **`wide`**: A floating-point number that represents the base width of a single crystal.
*   **`high`**: A floating-point number that sets the maximum height of the crystals (the crystals vary in height).
*   **`side`**: An integer that represents the number of sides for each crystal shape (e.g., 6 for a hexagonal crystal, 4 for a square).
*   **`dropoff`**: A floating-point number between 0 and 1 that influences how rapidly the height of the crystals decreases as they get farther from the center. A lower number would mean shorter outer crystals, and values close to 1 will give almost no height difference based on distance to the origin.
*   **`bouquet_angle`**: A floating-point number (in degrees) that controls the angle of the outward tilt of the crystals.
*   **`density`**: A floating-point number that influences how closely packed the crystals are. Higher numbers will produce more packed crystals. This is related to `R_max`, which I calculate as `wide*num/density`.
*   **Crystal base:** The crystals should be based on cylinders with tapered tops, much like a classic crystal shape.

**Specific details on arrangement and shape:**

*   **Random Placement:** The crystals should be placed in a circular arrangement, with the radius and angle of each crystal's position determined randomly using the `seed`. The distance from the origin for each crystal should be no more than `R_max` and the angle distributed from 0 to 360 * 10.
*   **Crystal Angle:** Each crystal needs to be angled outward from the center sphere, according to `bouquet_angle`. The actual angle of each crystal should be modified according to the angle of each crystal and its distance from the origin using the calculations provided.
*   **Crystal Height:** The height of each crystal is determined by `high` but is further modified using the equation `high*exp(-pow((rad[i]/(dropoff*R_max)),2))` so that the crystals closer to the center will be the maximum height and those near `R_max` will be shorter.
* **Base sphere:** There should be a central base sphere for the crystals. The radius of this sphere should be a function of `bouquet_angle`, `R_max`, and `hyp` using the equations `hyp=R_max/sin(bouquet_angle)` and `adj=R_max*cos(bouquet_angle)/sin(bouquet_angle)`.
* **Base removal:** The base sphere and the crystals should be cut by a cube that has a depth of `hyp`. The purpose is to create a flat plane of the sphere with crystals growing out of it.

**What I need from the SCAD file:**

*   All parameters should be clearly defined at the top of the file for easy editing.
*   The code should use the built-in `rands()` function in OpenSCAD to generate random numbers based on the `seed`.
*   The final object should be a single, combined shape made using `union()` and `difference()`.
*   I would like you to include the `crystal` module so that I can examine how the shapes are generated.

I believe that should cover it. I am not using any specific libraries, just the standard OpenSCAD built-ins.

Okay, I'm looking to create a printer calibration test, specifically for testing the tolerances my printer can handle. I'd like a design that has a central cube, and then four additional cubes surrounding it. These cubes should each have different clearances from the center cube. Specifically, two cubes will have a gap of 0.5mm between them and the central cube, and two cubes will have a gap of 0.7mm. I’d also like a marker, a cylinder, offset diagonally from the central cube.

Here's the breakdown of what I'm envisioning:

*   **Central Cube:** This will be the main reference point.
*   **Four Surrounding Cubes:** These will be placed along the X and Y axes, with two cubes on either side of the center cube.
*   **Two Tolerance Values:** Two of the surrounding cubes will be placed 0.5mm away, and two will be placed 0.7mm away from the central cube. The cubes with the same tolerance will be placed on the same axis relative to the central cube.
*   **Marker:** A cylinder will be placed diagonally from the central cube, using the same dimensions as a surrounding cube as part of the calculation of its position. The marker should be slightly smaller than a cube.
*   **Parametric Design:** I need to be able to easily adjust several things:
    *   The cube height
    *   The side length of the cubes
    *   Both tolerance values (the 0.5mm and the 0.7mm values)
*   **OpenSCAD:** I need this as an OpenSCAD file with the `//` style comments, not the `/* */` style.

Could you help me generate an OpenSCAD file that can accomplish this? I am not using any libraries for this project.

Okay, I'm looking to create a customizable drilling template for woodworking or other projects, and I'd like it to be parametric so I can easily adjust the dimensions. I have a basic idea in mind based on a design I found, but I need to be able to control a few key things.

Here's what I need the template to do:

*   **Base Shape:** The template will essentially be a rectangle with a cut-out section for a leg.
*   **Leg Spacing:** I need to be able to control the spacing from the edge of the template to the edge of the leg area:
    *   `xEsp`: The spacing on the X-axis (in millimeters).
    *   `yEsp`: The spacing on the Y-axis (in millimeters).
*   **Leg Dimensions:** I need to define the size of the leg cutout:
    *   `xLeg`: The length of the leg on the X-axis (in millimeters).
    *   `yLeg`: The length of the leg on the Y-axis (in millimeters).
*   **Drilling Hole:** The template will have a drilling hole in the center of the leg cutout.
    *   `hDia`: The diameter of the drilling hole (in millimeters). This should be adjustable.
*   **Support Structure:** I need a triangular "transversal" support structure connecting two sides of the leg cutout.
*   **Cutouts:** There needs to be cutouts for proper printing:
    *   A downward cutout around the main body
    *   An upward cutout around the main body
    *   A slant cutout running diagonally.
*   **Quality:** The circle and curves should be high quality.
*   **Units:** Everything should be in millimeters.

I'd like to be able to easily change all of these parameters.

I've tried my hand at an OpenSCAD file, but it's a bit messy. I also think it could be more elegant, and I'm hoping you can help with that.

I'm not expecting you to use any external libraries, just pure OpenSCAD.

Okay, I'd like to request a parametric OpenSCAD design for a docking connector, inspired by the HackDock project. I've seen the original design and have some specific requirements and preferences, but want it to be highly customizable.

The basic concept is a two-part connector: a main body and a lid. The main body should have a cavity to hold various cables and plugs, and the lid attaches on top. The connector needs to have openings for the cables to exit and also zip tie attachment points. It's designed to be a "one-click" docking solution for a laptop, consolidating multiple connections into a single physical connection.

Here's a breakdown of the specific parameters I need:

**General Dimensions:**

*   `width`: The overall width of the connector. This will be measured based on my laptop's plugs and cable protrusion plus a bit of buffer for the connector walls.
*   `length`: The overall length of the connector, measured between the outer connectors plus a bit of a buffer.
*   `height`: The overall height of the connector's base, measured from the table up to the top rim of the thickest plug, plus some extra room for Sugru or other filler material.
*   `wall`: The wall thickness of the connector.
*   `slide`: A small offset (wall thickness + a small increment, like 0.15mm) for sliding parts between the lid and the base.

**Main Body Parameters:**

*   `cableopening`: The width of the opening in the back of the connector where the cables come out.
*   `ziptieopening`: The width of the openings for zip ties in the back of the connector. I may not always need these, but I'd like the option to have them.

**Lid Parameters:**

*   The lid should fit snugly onto the base and have appropriate protrusions to hold it in place, also taking the `slide` parameter into account.

**Functional Requirements:**

*   The design should include a `roundedBox` module for rounded corners, with configurable radius, and should support creating both a rounded box and rounded box sides (as seen in the included code).
*   The design should have the main body (base) which is the main cavity, and the lid that closes on top.
*   The base should have an inner cavity, as well as cable exit and ziptie openings, and lower gripper elements to help hold the lid in place.
*   The lid should have corresponding elements to slide into and hold on to the base (including upper and lower grippers).
*   All dimensions should be customizable using the parameters I listed.

**Code Style Requirements:**

*   Please keep the code well-organized, with comments explaining each section.
*   Use modules for each of the distinct parts of the connector: basic shape, inner cavity, cable openings, zip tie openings, the lid, and any other major pieces.
*   Make sure there are no hardcoded dimensions. Everything should be derived from the given parameters.
*   For the rounded box module I will be using the library shown in the example code.

**Libraries**

* I will be using a `roundedBox` from the example code and will not need a specific library for that module.

I think that covers everything. I'm eager to see what the AI assistant creates. Let me know if you have any clarifying questions.

Okay, I'm trying to design a customizable box, and I've seen a design that's pretty close to what I need called the "HackDock Base Unit". I like the overall approach, but I want to be able to adjust more of the parameters, and I want the AI to generate the code for me.

Here's what I'm thinking. The HackDock Base Unit is basically a rectangular box with a lid that slides on. I need to be able to define all the dimensions: the inner height, the overall width, and the overall length of the box. I also need to specify the thickness of the walls - basically, all the structural parts. I want it to have rounded corners, like the HackDock.

Now, for the cutouts, I need more flexibility.

First, there's a main I/O opening on one side, and I need to set its width. The height of this one should always be maximized to the height of the usable space (innerheight, as defined above). Then I need two more openings on that same side; these will need their own width and length settings. On an adjacent side, I need two *more* openings, also with their own length and width settings. I want to be able to use a variable to describe the distance between all four of those openings (two per side).

For the lid, I need to control the sizes and locations of the mounting holes, including the four standard VESA mounting holes and a single center mounting hole. VESA mounts have a settable distance between the mounting holes (75mm or 100mm, for instance), and I need to set that parameter. And of course, I need to specify the diameter of all the screw holes.

Finally, I need the lid to have "click-in noses" that secure it to the box, and I need to control how far these slide in (some adjustment for manufacturing tolerances, presumably). I should also be able to turn this feature on or off since I could potentially use screws instead. If I do use the click in part, I need to be able to adjust the length and height of the actual cutouts on the base for this feature. The 'slideadjust' parameter in the file I've seen looks useful here.

I'd like the OpenSCAD code to be fully parametric, so I can change these parameters and have the box update automatically. The rounded corner function is great, and it needs to be included (or I would be fine with using a library that already has a rounded corner function). I also need to make sure the library used for the rounded corner feature is fully contained within the final generated .scad file to avoid library dependency issues. The original design had a `roundedBox` function inside the file, and I would like to keep that. If I do need a library, I would prefer it to be a more basic one such as MCAD.

I'd like it so that I can choose to render just the box, just the lid, or both.

Could you please generate the OpenSCAD code for this?

Okay, I've been playing around with OpenSCAD and made a simple helical coupling, and I'd like to take it to the next level. I'm looking for a parametric design that is more robust and customizable.

Here's what I'm envisioning:

**Core Concept:** A helical coupling that connects two shafts of potentially different diameters. The design should have cylindrical hubs at each end for connecting to the shafts and a flexible helical section in the middle.

**Key Parameters (I want these to be customizable):**

*   `coupling_outer_dia`: The outer diameter of the main coupling body.
*   `hole_dia_top`: The diameter of the hole for the shaft on the top (or larger diameter) side.
*  `length_top`: The length of the top hub (the cylindrical part that contains `hole_dia_top`)
*   `hole_dia_bottom`: The diameter of the hole for the shaft on the bottom (or smaller diameter) side.
*  `length_bottom`: The length of the bottom hub (the cylindrical part that contains `hole_dia_bottom`)
*   `helix_length`: The axial length of the flexible helical section.
*   `helix_twist`:  The number of 360-degree twists in the helix, e.g., 2 would be two complete rotations.
*   `helix_inner_dia`: The inner diameter of the helix; controlling how much material is removed when creating the helix.
* `screw_diameter`: The diameter of the holes for set screws in the hubs (should be the same for top and bottom)
*   `screw_offset_radius`:  The radial distance from the center of the hub to the center of each set screw hole.

**Features:**

*   **Cylindrical Hubs:**  Solid cylindrical hubs at the top and bottom of the coupling, with holes for the shafts (`hole_dia_top` and `hole_dia_bottom`) going through them.
*   **Set Screw Holes:** Each hub should have two radial set screw holes for better gripping of the shafts. The location of these holes should be customizable via `screw_offset_radius`. I think I want them 90 degrees apart.
*   **Helical Section:** The center should be a helix formed by a "removed" square. This should create a spring-like structure with customizable length and twist. The inner radius of the helix should be customizable using `helix_inner_dia`.
*   **Parametric Design:**  All the dimensions should be easily adjustable via parameters at the beginning of the file.
*   **Commented Code:** The code should be commented to explain the design.
*   **Flexibility:** The design should allow for some flexibility in shaft alignment and should be relatively printable.

**Additional Considerations:**

*   I'd like the top and bottom hubs to connect seamlessly to the helical section so there aren't any sharp corners or discontinuities at the transition.
*  It would be nice if it had more of a "spring-like" appearance.
*   I'd like the set screws to be a reasonable distance from the shaft hole.
* I would like to use a higher `fn` for the circles. Something like 100.

**Libraries:**

I don't think I need any special libraries for this. It seems fairly straightforward.

Could you please generate an OpenSCAD file with all these parameters? I'm hoping this will be a more flexible and reliable version of my original coupling.

```

// Tip: Make the larger rod hole the upper one

// Outer diameter of the coupling
coupling_outer_dia = 20;

// Diameter of the upper hole
hole_dia_top = 10;
// Length of the holder for the upper hole
length_top = 10;

// Diameter for the lower hole
hole_dia_bottom = 6;
// Length of the holder for the lower hole
length_bottom = 10;

// Length of the helix itself
helix_length = 10;

// Hole size for the fastener screws
screw_diameter = 3;

$fn = 100;

// Top
translate([0,0,helix_length+length_top/2])
rod_connector(length_top, coupling_outer_dia, hole_dia_top, screw_diameter);

// Bottom
translate([0,0,-length_bottom/2])
rod_connector(length_bottom, coupling_outer_dia, hole_dia_bottom, screw_diameter);

// Helix

  circle(r=coupling_outer_dia/2);
  circle(r=coupling_outer_dia/4);
  translate([-coupling_outer_dia/2,0])
  square([coupling_outer_dia, coupling_outer_dia]);
}

  rotate([0,90,90])

Okay, I've been messing around with this really cool customizable ruler script I found, and I'd love to expand on it. It's called "Ruler-custom-mark-v7.6-forweb.scad". The current version is pretty neat, it uses the `write/Write.scad` library to generate raised text and sunken rule markings on a ruler, and has parameters for length, width, bevels, text, and line depths etc. I'm hoping you can help me create an even more advanced, parametric version that allows for additional customization.

Here's what I'm thinking:

**Core Functionality (Keep these from the existing design):**

*   **Ruler Body:** The basic rectangular prism shape with a bevel on the scale side.
*   **Scale Markings:**  Sunken (engraved) major and minor lines at cm and mm intervals, respectively.
*   **Text:**  Raised text (using the `write/Write.scad` library) for personalization and markings.
*   **Key Hole:** The optional circular hole for a keychain.
*   **Units:** Everything is in millimeters (mm).

**New Parametric Features I'd like to add:**

1.  **Customizable Scale Intervals:** Instead of just mm and cm, I want to be able to specify the major and minor scale intervals as parameters. For example, I might want major divisions at 2 cm and minor at 5 mm.
2.  **Line Style:** Add a parameter to choose between solid, dashed, or dotted lines for the scale markings. If dashed or dotted, I'd like to control the length of the segments and spacing.
3.  **Variable Text Placement:** Rather than just left/top displaced, I would like a parameter that allows setting x/y coordinates, and also an alignment (left, center, right) option for text.
4.  **Multiple Text Lines:** I would like to be able to define a string as a multi line string (e.g. "\n") and be able to produce that on the face of the ruler. Perhaps a list of text and their locations?
5. **Rounded Corners:**  Add a parameter to control the radius of rounded corners on the ruler.
6. **Notches:** Add a parameter to allow user-defined notches along the ruler edge. These should have a width, depth, and spacing parameters.
7.  **Material Thickness:** I'd like to have a parameter called `material_thickness`, that controls the height of all parts of the ruler and makes sure the depth/lineheight never goes beyond the ruler height.
8. **Engraving depth**: rather than just `LineDepth`, I'd like to be able to specify a `text_depth` and `scale_depth` parameter, this should be able to go positive or negative.
9. **Text style**: I would like to be able to control the text style (font) through use of the `font` parameter for the `Write.scad` library

**Things I want to keep in mind:**

*   **`Write.scad` library dependency:**  The code should still use the `write/Write.scad` library for text generation.
*   **OpenSCAD-friendly:** The new script should be easy to customize and use within OpenSCAD.
*   **Clarity:** The code needs to be clear and commented so I can understand how it works.

**Parameters I anticipate:**

*   `ruler_length`
*   `ruler_width`
*   `bevel_width`
*   `font_size`
*   `number_size`
*   `text_height`
*   `hole_radius`
*   `material_thickness` (replaces `RulerHeight`)
*   `bevel_height`
*   `line_width`
*   `text_x`
*   `text_y`
*   `number_offset`
*   `major_interval`
*   `minor_interval`
*   `line_style` (`solid`, `dashed`, `dotted`)
*   `dash_length` (if line style is dashed)
*   `dash_spacing` (if line style is dashed or dotted)
*   `dot_spacing` (if line style is dotted)
*   `text_align` (`left`, `center`, `right`)
*   `text_lines` (a list of strings for text on different lines)
*  `text_locations` (a list of lists [x,y] corresponding to the text lines)
*   `corner_radius`
*   `notch_width`
*   `notch_depth`
*   `notch_spacing`
*   `scale_depth`
*  `text_depth`
*  `font`

I know that is quite a bit, but I think it would make an incredibly powerful and versatile ruler generator. I'm really excited to see what you come up with! Let me know if you need any clarification!

Okay, I'm working on a design for a Babbage Difference Engine, and I've got a good chunk of it modeled in OpenSCAD, but I'm hitting a wall with some of the more complex mechanisms. I've included my current file, `DifferenceEngine.scad`, which uses the `MCAD/involute_gears.scad` and `pins/pins.scad` libraries. I'm using `$fn=50` for general smoothness, and I've got a few parameters defined at the top: `tab_offset`, `sliding_tab_offset`, `bearing_thickness`, `view` (for isolating parts), `bottom_plate_thickness`, and `stack_height`.

Here's a breakdown of what I have and what I need help with:

**Current Functionality:**

*   **Basic Components:** I've got modules for creating gears (`make_a_gear`), arcs (`arc`), technic axles (`technic_axle`), interlocking tabs (`interlocking_tab`), the figure wheel (`figure_wheel`), the sector wheel (`sector_wheel`), sector wheel tab (`sector_wheel_tab`), figure wheel restore arm (`figure_wheel_restore_arm`), sector wheel restore arm (`sector_wheel_restore_arm`), and the two bottom plates (`bottom_plate_one` and `bottom_plate_two`). I also have the `sector_wheel_lift_plate` and `sector_wheel_bearing_plate`.
*   **Assembly:** The `if (view==0)` block displays a rudimentary assembly. I'm using the `view` parameter to isolate individual components.
*   **Libraries:** I am making use of `MCAD/involute_gears.scad` for gear generation and `pins/pins.scad` for pin features.

**Missing Mechanisms and Requests:**

I need your help to design the following mechanisms as parametric OpenSCAD modules:

1.  **Carry Mechanism:** This is crucial for the engine's function. I need a mechanism that will transfer a carry from one wheel to the next when it completes a full rotation (specifically, a carry from the figure wheels to the sector wheels and from one sector wheel to the next). This mechanism needs to be able to be added to both the figure wheel and sector wheel axles. It should engage with the gear on the neighboring wheel. I'd like parameters to adjust the throw distance and the engagement geometry. This should not be a simple gear, but instead a pawl/ratchet style mechanism that would require a small amount of rotation from the wheel to trigger the carry, allowing for an over-travel/slop of rotation in the figure wheels.
2. **Timing/Lift Mechanism:** I need a mechanism that, when the sector wheel rotates to a certain point in it's movement, will engage the lift plate and lift the next figure wheel up a small amount, allowing it to be rotated. Once this rotation is complete, the lift mechanism would be disengaged and the figure wheel lowered again. The lift height and timing should be adjustable parameters. A possible method would involve a cam system on the sector wheel that will activate an arm to lift the lift plate.
3.  **Detents for Wheels:**  I need a reliable method to prevent unwanted rotation of the figure wheels and sector wheels, essentially a locking mechanism. This will likely involve a spring-loaded detent that interacts with indents on the wheels themselves. I need parameters to adjust the strength of the spring, as well as the number and depth of detents. This should allow for rotation in only one direction.
4. **Thrust Bearings:** I'd like to add some basic thrust bearings to the wheels and axles to reduce friction. I'd like a generic module that I can apply to any cylinder, including a parameter for the thickness of the bearing and diameter.

**Parametric Design:**

Please ensure all the modules are parametric, so I can adjust them easily. I'd like the parameters to control things like:

*   Sizes (diameters, thicknesses, lengths, offsets)
*   Engagement (carry throw, pawl engagement, lift height)
*   Spring strength (detents)
*   Material (though this will only be for visual representation, not physics simulation)

**Integration:**

I'd like the output to be in .scad format, and I plan to integrate these new modules into my existing `DifferenceEngine.scad` file. Therefore, try to use a consistent naming convention. Please provide guidance on how the new modules should be incorporated in the current `DifferenceEngine.scad` file and into the current structure.

I think these additions will complete the functional aspects of my engine, and I look forward to your assistance. Let me know if you need more clarification on any of the described features.

Okay, so I'm looking to create a parametric coin tube generator in OpenSCAD, similar to the one I've been using but I'd like it to have some more flexibility and a cleaner code base. I've been using this `coin_tube_1_3_1.scad` file, and while it works, it's a bit clunky and hard to modify.

Here's what I need:

**Core Functionality:**

*   **Parametric Coin Support:** The design needs to be driven by a `coin_type` parameter, which would select from a list of predefined coins. Each coin should have data for its name, diameter, and height.
*   **Tube Generation:** Based on the selected coin and the number of coins to store (`number_of_coins`), the script should generate coin tubes. It would be great if the tubes could be generated at an offset for easy printing.
*   **Cap Generation:** The design should include an optional cap that fits the generated coin tube, also controlled by a `generate_cap` parameter. This cap needs to have a snug fit and I would appreciate a fudge factor for better tuning.
*   **Customizable Parameters:**
    *   `number_of_coins`: Number of coins each tube should hold.
    *   `number_of_tubes`: Number of tubes to generate.
    *   `generate_tube`: Boolean to toggle tube generation.
    *   `generate_cap`: Boolean to toggle cap generation.
    *   `tube_wall`: Wall thickness of the tube.
    *   `clearance`: Clearance between coin and the tube wall.
    *   `fudge_factor`: Adjust the cap's size for better fit (e.g., 0.975).
*   **Clearance for Printing:**  There should be a small clearance between the inner diameter of the cap and the outer diameter of the tube so they can actually fit.

**Specifics:**

*   **Coin Data:** I need to have a data structure (like an array of arrays) holding the coin data (name, diameter, height) for various coins (e.g., Euros, US Dollars, Canadian Dollars, Mexican Pesos).  The current file has this so please keep the current coin selection.
*   **Tube Length:** The internal tube length should be two coins higher than the number of coins it is intended to fit.
*   **Cap Fit:** The cap should have a recessed section that fits inside the tube and it should have a solid top.
*   **Modular Design:** The code should be easy to read, maintain and modify and I prefer a more modular design where the tube and cap generation are in separate modules.
*   **User Interface:** The parameters at the top of the script should be easily modifiable to change parameters.

**Libraries:**

I'm not specifically requesting any library, but if you are to use one, I am fine with that.

Essentially, I'd like a cleaner, more flexible version of the existing script, with the same functionality but in a modular and better structured format.  I think it would really help my coin organization. Can you design a script in OpenSCAD to do this?

Okay, here's what I'm looking for. I've seen a cool customizable cable holder on Thingiverse that I really like, but I want to make a new version with some different parameters and a slightly different design approach. It's a captive cable holder, meaning the inner part rotates within the outer part, and once you put the cable in, it can't fall out. The original is called "Customizable Cable Holder" by xifle, but I'm looking to do something a bit different.

Here's a breakdown of what I need, including the features I want to control with parameters:

**Overall Design:**

*   The design should consist of two main parts: an outer holder and a rotating inner barrel.
*   The inner barrel is captured within the outer holder and can rotate freely.
*   The cable sits in a groove within the inner barrel.
*   The assembly attaches to a table edge using tabs.

**Key Parameters:**

*   `cable_diameter`: The diameter of the cable that the holder will accommodate (in mm).
*   `table_thickness`: The thickness of the table edge where the holder will be attached (in mm).
*   `tolerance`: The clearance between moving parts (in mm).
*   `tab_length`: The length of the tabs that hold the holder to the table (in mm).
*   `tab_thickness`: The thickness of the tabs (in mm).
*   `grip_height`: The height of the triangular grip protrusion on the lower tab (in mm).
*   `grip_width`: The base width of the triangular grip protrusion (in mm).
*   `thumbwheel_height`: The height of the thumbwheels at the top and bottom of the inner barrel (in mm).
*    `retainer_factor`: This one is a bit confusing, but it seems to control the lift and amount of material in the middle barrel. I'd like to have a range like `[3,4,5,6,7,8,9,10]`
*   `plane_cut_factor`: This seems to control the depth of a slice in the overall holder, range should be [0, 2]
*   `neck_thickness`: The thickness of the inner rotating cuff (in mm).
*    `holder_thickness`: Controls the overall thickness of the outer holder (in mm).
*   `barrel_lift_factor`: The height the retaining barrel is lifted
* `barrel_thickness`: The thickness of the retaining barrel

**Specific Features and Requirements:**

*   **Inner Barrel:**
    *   The inner barrel should have a groove/channel for the cable to sit in.
    *   There should be "thumbwheels" at the top and bottom to make rotation easier.
    *   It needs to rotate freely inside the outer barrel.
*   **Outer Holder:**
    *   The outer holder should fully enclose the inner barrel.
    *   It needs to be designed so that the inner barrel is captive but can still rotate.
    *   The outer holder should also include the mounting tabs.
*   **Table Tabs:**
    *   The tabs that attach to the table edge should be designed to hold securely.
    *   The lower tab should have a triangular grip protrusion for better hold.
*   **Printing:**
    *   The design should be printable in a single piece (though I'd like the *option* to print it in two parts for machines that struggle with tight tolerances). The user should be able to select `show_seperate = "yes"` or `show_seperate = "no"`
     *   The STL should be oriented to allow for no supports.
*   **OpenSCAD:**
    *   The design should be fully parametric in OpenSCAD, meaning that all of the parameters listed above can be easily changed.
    *   I'd like for the script to include color highlights using `preview_tab` so it's easy to see the different features in a 3D preview.
    * I would like to add a $fn variable to control the number of sides of the circles used for the cylinders.
    *  Please add a `highlight` module for applying color for the `preview_tab` parameter.

**Output:**

I am looking for a fully functional OpenSCAD file that I can use.

I'm hoping this is clear! Let me know if you have any questions.

Okay, I'm looking to design a speaker holder that will let me mount a small, round speaker that doesn't have its own mounting holes. I've got a rough idea of what I want, and I'd like to make it parametric in OpenSCAD so I can easily adjust it for different speaker sizes and mounting situations.

Here's the basic concept:

The holder will have a circular cutout in the center to hold the speaker. This cutout needs to have two levels - one deeper level that the speaker flange sits on and then a slightly smaller diameter cut that allows the sound to escape. Around the speaker cutout, there needs to be a larger circular base with mounting tabs on opposite sides. Each tab will have a screw hole.

Here are the specific parameters I need to be able to adjust:

*   **`cross_length`**: The total length of the holder across the mounting tabs (not including the tabs themselves).
*   **`cross_width`**: The width of each mounting tab.
*   **`holder_diameter`**: The diameter of the larger circular base of the holder. This should be a bit bigger than the speaker's outer diameter.
*   **`speaker_diameter`**: The diameter of the speaker itself.
*   **`screw_radius`**: The radius of the screw holes in the mounting tabs.
*   **`flange_depth`**: The depth of the recessed area where the speaker flange sits.
*  **`flange_width`**: The difference in radius between the flange area and the main speaker cutout.
*   **`height`**: The total height/thickness of the holder.
*   **`bounding_size`**: The length and width of the bounding box the main part fits within. This doesn't need to be user adjustable as it depends on `cross_length` and `cross_width`. Specifically this will be `cross_length + cross_width`.

I need the design to use simple extrusions and circles and unions and differences. Specifically,

1. The main body should be a cylinder with the `holder_diameter`. Then two tabs should be added on opposite sides. The tab assembly should be created via a hull with two `cross_width` diameter circles centered on x positions of +/- `cross_length`/2, rotated about the z-axis by 0 and 90 degrees, respectively. Then each tab has a single screw hole, represented by a circle at the center of each tab. The whole structure should be extruded by `height`.
2.  The speaker cutout should be a difference of two cylinders. The first cylinder should have a height equal to `flange_depth` and a radius of `speaker_diameter / 2`, and the second cylinder should have a height equal to `height` and a radius of `speaker_diameter / 2 - flange_width`.
3. This whole speaker cutout should be subtracted from the extruded main body.
4. Finally the entire shape should be reflected vertically about the xy plane, so that the deeper speaker cut is on top.

I do not need any external libraries. Can you generate an OpenSCAD file that implements this parametric speaker holder?
