Hey, I'm looking to create a customizable text object in OpenSCAD, and I'd like a bit of flexibility in how it's put together.

I need to be able to have two separate text strings, each with its own set of parameters. So for each text, I need to be able to control:

*   The text content itself
*   Font size
*   Extrusion height (depth)
*   X, Y, and Z position in space
*   Rotation around X, Y, and Z axes
*   The font face to use (and ideally be able to choose from a long list of options, or maybe even allow the user to specify their own).

I also want to be able to connect these two text objects with a connecting shape. This connector should also be parametric, allowing me to choose between a box and an ellipse as the connector shape. The connector shape should also have adjustable X, Y, Z position, width, depth, and height.

Could you generate the OpenSCAD code for this?

I need a parametric OpenSCAD design for a hose adapter. This adapter should connect two hoses or pipes with different diameters, with one hose sliding *inside* one end of the adapter, and the other hose sliding *over* the other end.

Here's how I envision it:

*   **Part A Inner Diameter:**  This is the *inner* diameter of the end that the hose will slide *into*.
*   **Part B Outer Diameter:** This is the *outer* diameter of the end that the hose will slide *over*.

I also want these parameters:

*   **Material Strength:**  A thickness value that determines how thick the walls of the adapter are.
*   **Slide-on Length:** This will be how long the 'slide-on' section is for *each* side of the adapter, where the hose connects.
*   **Connection Length:** This will be the length of the section *between* the two "slide-on" parts.
*   **Slide-on Ramp:** This is a slight ramp effect at the beginning of each slide-on section, creating a tighter fit as the hose is pushed on. It should start slightly *smaller* than the target diameter and then widen to slightly larger at the end of the section. This way you can really press the hose on tight!

I'm imagining the adapter is shaped like a cylinder. Part A starts with a smaller inner diameter, ramps up slightly, then keeps that diameter over the 'slide-on length'. It also has a wall thickness defined by the material strength parameter.

The connection section should smoothly go from the end diameter of part A to the beginning diameter of part B (which should also have a slight ramp). Part B then continues its 'slide-on length' to the defined outer diameter.

I'd like to be able to set the fragment count for the circles. I also want the default orientation to be standing on end, along the z-axis.

Could you create this design in OpenSCAD? No external libraries are needed.

Hey, I'm looking to design a parametric impeller for a ducted fan, and I'd like to use OpenSCAD. I've been messing around with an existing customizer, and I think I have a decent handle on what I need now, but I'd really like a clean implementation that I can further modify.

I need to be able to control the following parameters:

*   **`show`**: An integer to choose what to display. `0` for the assembled impeller (top and bottom), `1` for just the printable top, `2` for just the printable bottom, and `3` for both printable parts side-by-side for easy printing.
*   **`total_height`**: The total outside height of the assembled impeller.
*   **`plate_thickness`**: The thickness of both the top and bottom plates.
*   **`outside_dia`**: The overall diameter of the rotor.
*   **`hub_dia`**: The diameter of a central hub that extends from the bottom plate (set to < 0 to disable the hub).
*   **`hub_height`**: The height of the hub extending from the top of the bottom plate.
*   **`nut_inset_dia`**: The diameter of a circular inset on the bottom of the bottom plate, designed to accommodate a nut. Set to < 0 to disable the inset.
*   **`nut_inset_height`**: The depth of the nut inset.
*   **`hub_recess_dia`**: The diameter of a circular recess on top of the hub (set to < 0 to disable).
*   **`hub_recess_height`**: The depth of the hub recess.
*   **`intake_dia`**: The diameter of the intake hole in the top plate.
*   **`num_vanes`**: The number of vanes in the impeller.
*   **`vane_thickness`**: The thickness of each vane.
*   **`shaft_dia`**: The diameter of the center shaft hole.
*   **`vane_start_dia`**: The diameter where the vanes start. Use the intake diameter if set to < 0.
*   **`direction`**: An integer to choose vane direction: `0` for counterclockwise, `1` for clockwise.
*   **`vane_fit`**:  A gap that controls how tightly the vanes fit into the top plate.
*   **`resfactor`**: An integer resolution factor, where 1 is low, 2 is mid and 3 is high.

The impeller should be constructed with the following design elements:

*   **Involute Vanes**: The vanes need to be based on involute curves. I know the formula, but I'd like your implementation.
*   **Top and Bottom Plates**: The design consists of a top and bottom plate, with the vanes extending from the bottom plate and fitting into the top plate.
*   **Fillets**: There should be a fillet at the base of each vane where they meet the bottom plate, with the fillet dimensions configurable (I don't have to have a variable for fillet radius - just choose something reasonable).
*   **Hub**: The central hub (if enabled) should have optional recesses on both the bottom for a nut inset and the top for an additional hub.
*   **Assembly**:  If `show` is set to `0`, the top plate should be rotated and translated into an assembled position, and the two plates should properly match up, with the vanes fitting correctly into the top plate cutouts.

I'd like to have a separate module for the involute curve generation since that could be reused, and another module for each of the top and bottom impellers. Finally, a module to assemble them all together. It would be really nice if the module parameter lists matched the global variables as closely as possible.

I'd prefer not to use any external libraries like MCAD or BOSL.

Thanks!

I'd like to create a customizable bookmark using a cellular automata algorithm. I have a basic design in mind, but I need an OpenSCAD file that allows me to easily tweak the parameters and generate different bookmark patterns. I'm looking for a parametric design where I can control things like the rule set for the automata, the initial line, overall bookmark dimensions, thickness, and the number of generations.

Here's a breakdown of the features and parameters I need:

**Core Functionality:**

*   **Cellular Automata:** The design should use a 1D cellular automaton. I should be able to specify the rule set, which will be an array of 8 values (0 or 1), representing the output for each possible neighborhood configuration.
*   **Initial Line:** I should be able to specify the initial state of the automaton as an array of 0's and 1's of any length, determining the starting line.

**Parameters:**

*   `regle`: Array of 8 integers (0 or 1), defining the cellular automata rule.
*   `lignedepart`: Array of integers (0 or 1) representing the initial line of cells.
*   `largeursignet`: Width of the bookmark.
*   `longueursignet`: Height of the bookmark.
*   `epaisseursignet`: Thickness of the bookmark.
*   `nbriterations`: Number of iterations of the cellular automata (generations). This also affects the number of rows in the bookmark design.
*    `enchevretrement`:  Overlapping factor for the cubic cells.
*   `avecsouscouche`: Boolean; if true, add an underlayer to the bookmark.
*   `epaisseursouscouche`: Thickness of the underlayer (only matters if `avecsouscouche` is true).

**Output:**

*   The OpenSCAD file should generate a 3D bookmark with the pattern created by the cellular automata, following the parameters I set. Each cell in the automata will be represented as a cube in the design.
*   If `avecsouscouche` is `true`, generate a base underlayer at the same width and height, with a specified thickness.
* The cellular automata should be toroidal. That is, cells on the edges will look at cells from the opposite edge.

I'd like the code to be well-structured and commented so that it's easy to understand and modify. Could you generate a parametric OpenSCAD file for this? Thanks!

[User]
I need a parametric drawer divider system, and I'd like to use OpenSCAD to generate the models. I'm envisioning a modular system with several different types of connectors and dividers that can be combined to organize drawers.

Here's what I need for the design:

**Global Parameters:**

*   **`part`**: A dropdown menu to select the type of part to generate. It should include options for:
    *   All connectors combined
    *   Zero length straight connector
    *   Straight connector
    *   Edgy T-connector
    *   Round T-connector
    *   Edgy X-connector
    *   Round X-connector
    *   Edgy corner connector (both inner and outer edges are edgy)
    *   Corner connector (outer edge is edgy, inner edge is rounded)
    *   Round corner connector (both inner and outer edges are rounded)
    *   Straight divider
    *   Divider with a lowered section
    *   Divider with a right bend
    *   Divider with a left bend
     *  All border connectors combined
    *   Border zero length straight connector
    *   Border straight connector
    *   Border edgy T-connector
    *   Border round T-connector
    *   Border edgy corner connector
    *   Border corner connector
    *   Border round corner connector
    *   Border divider parts
*   **`height`**: The overall height of the dividers and connectors.
*   **`width_bottom`**: The width of the divider/connector at the base.
*   **`width_top`**: The width of the divider/connector at the top.
*   **`connector_length`**: The length of the connector pieces.
*   **`border_overhang`**: An overhang value, used for border pieces to accommodate non-vertical drawer walls.
*   **`snap_connection_size`**: A size for the bump on the connectors to make a "satisfying click" during assembly, set to 1mm by default, and should be able to be set to zero to disable the feature.

**Divider Settings:**

*   **`divider_length`**: The length of the straight dividers.
*   **`bend_radius_factor`**: A factor relative to the `divider_length` used to calculate the radius for the bend dividers.
*   **`bend_distance`**: The horizontal displacement for bend dividers.
*   **`lowered_height`**: A factor (between 0 and 1) specifying the height of the lowered section of the lowered divider, relative to total height.
*   **`lowered_radius1_factor`**: A factor to determine the radius for the lowering on one side of the lowered divider.
*   **`lowered_radius2_factor`**: A factor to determine the radius for the lowering on the other side of the lowered divider.

**Tolerances:**

*   **`gap`**: Horizontal gap between parts.
*   **`gap_top`**: Vertical gap between parts.

**Internal Parameters:**

*   `$fa`: $fa for circles.
*   `$fs`: $fs for circles.
*   **`line_up_space`**: Space used when multiple pieces are in one .stl file.

**Connector Details:**

*   The connectors should have a male fitting on each side. The male fitting should be a truncated conical shape with a rounded end.
*   The "T" and "X" connectors should have the option to be "edgy" (sharp corners) or "round" (filleted corners).
*   The corner connector should have options for both inside and outside corners to be either edgy or rounded.
*  The border connectors should have the same male fitting as the regular connectors.
*  The border connectors should be thinner to accommodate a thinner drawer border or a not-fully-vertical drawer wall.

**Divider Details:**

*   The straight dividers should have a female fitting at both ends.
*   The lowered divider should have the center lowered on the top part. The amount of lowering should be parametric, as should the radius of the curves where it blends into the non-lowered section.
*   The bend dividers should bend at 90 degrees. The bend radius should be adjustable.

**Output:**

*   The script should be able to generate individual STL files for each part type. When the `part` variable is set to a value ending in `_all` multiple parts should be output in the same stl file, spaced out by line_up_space.
*   The STL files need to be printable without supports.
*   The generated parts should fit together smoothly, accounting for the specified gaps and tolerances.

I think this is comprehensive.  I don't expect you to use any libraries but please let me know if you think it would help. Can you generate the OpenSCAD files for this design?

I need a parametric OpenSCAD design for a watch case opener, specifically for the kind that has multiple pins that fit into the notches on the back of a watch. I've seen a few designs out there, but I want one that's easily customizable.

Here are the key parameters I'd like to be able to adjust:

*   **`pin_dist_inner`**: This is the crucial one – it’s the inner diameter, or distance across, between opposite pins. So, the diameter of the circle formed by the pins.
*   **`pin_thickness`**: The thickness of each pin.
*   **`pin_num`**: The number of pins the opener will have. This needs to be easily adjustable for watches with different pin counts.
*   **`handle_length`**: The length of the handle.
*   **`handle_width`**: The width of the handle.

The design should consist of:

*   A central disc. This should be slightly larger than the pin circle to allow for pin placement. It should have a recessed central area to form a "lip".
*   The pins, evenly spaced around the perimeter of the disc at the correct radius.
*  A handle attached to the central disc. The handle should be centered on the disk diameter (x axis) for ergonomic use.

Ideally, this would be set up so that I can use the Thingiverse Customizer to adjust these parameters. Could you also include comments in the code to explain each section and parameter?

I also want to be able to easily use different colors for different parts of the opener, so please include color() calls before each main component. And please do not use any libraries other than the standard OpenSCAD library.

[Assistant]
customizable_watch_opener.scad:
```
// inner distance between opposite pins
pin_dist_inner = 34.3;
// thickness of pin handle
pin_thickness = 1.6;
// number of pins. normally it's 6
pin_num = 6;
// length of handle. longer is easier to hold
handle_length = 76;
// width of handle.
handle_width = 8;

// [hidden]

// cicle
color("red")
difference(){
    cylinder(h=8,d=(pin_dist_inner + 4));
    translate([0,0,-1])
        cylinder(h=10,d=pin_dist_inner - 2);
};

// pins
color("blue")
for (i=[0:pin_num]){
    rotate([0,0,(360/pin_num)*i])
        translate([(pin_dist_inner + 4)/2-2,0,0])
        cube([4,pin_thickness,10]);
};

// handle
translate([-4,-1*(handle_length/2),0])
    cube([handle_width,handle_length,5]);

I need a parametric tool for opening watch cases, similar to the design I saw online. It's essentially a circular base with pins that engage with the watch case back, and a handle for applying torque.

Here are the key parameters I'd like to control:

*   **`pin_dist_inner`**: This is the inner distance between opposite pins, which determines the diameter of the circle where the pins make contact with the watch back.
*   **`pin_thickness`**: The thickness of each pin.
*   **`pin_num`**: The total number of pins equally spaced around the circle. Typically this is 6, but I'd like to be able to adjust it if necessary.
*   **`handle_length`**: The length of the handle.
*   **`handle_width`**: The width of the main part of the handle.
*   **`wf`**: A widening factor that controls how much wider the knobs at the end of the handle are compared to the main handle width.
*   **`pin_length`**: The length of each pin.

The base should be a cylindrical disc with a hollowed center, and the pins should extend upward from the base. The handle should be a bar extending from the edge of the base. It should have a slight chamfer along its length and rounded knobs at each end to make it more comfortable to grip and turn.

Could you generate the OpenSCAD code for this, using the above parameters? The handle should be connected to the base on the *top* of the cylinder. I'm envisioning a single .scad file. I'm not using any libraries at this time.

I'm looking for an OpenSCAD design for a clip that will hold pan lids inside cabinet doors. I need it to be parametric so I can easily adjust it for different lid thicknesses and screw sizes.

The clip should consist of three main parts: a rectangular base that attaches to the cabinet door, a curved "pie" piece that provides some support, and a beam angled away from the base that actually holds the lid. There should also be a mounting hole for a screw, countersunk for a flat head or a countersunk screw.

I need to be able to control these parameters:

*   `base_size`: the width and depth of the rectangular base.
*   `base_height`: the height of the rectangular base.
*   `mounting_hole`: the diameter of the mounting screw hole.
*   `screw_head`: the diameter of the screw head.
*   `screw_head_angle`: the angle of the countersink for the screw head (0 for flat bottom, use higher values for a countersunk screw).
*   `keep`: the depth to which the screw can grip before it reaches the inside of the cabinet door.
*   `beam_length`: the length of the angled beam.
*   `angle`: the angle of the beam relative to the base, 0 would be a 90-degree angle.

I would like the design to use the `arc.scad` library to generate the curved "pie" piece. I know that this library contains two functions: `2D_arc` and `3D_arc`.

Also, I'd like it if the three components are in different colors (e.g., yellow for the base, red for the pie piece, and green for the beam) so that it's easier to visually debug when I adjust the parameters. I've included a file that describes most of what I'm after.

Could you please generate the necessary OpenSCAD code?

Hey, I'm looking to design a cool 3D printable object that involves nested cubes, kind of like those Russian nesting dolls but with cubes. I want each cube to be a frame, not solid, and they should get progressively smaller as they nest inside each other.

Here are the key features I'm thinking of:

*   **Nested Cubes:** I want to define how many cubes there are.
*   **Cube Size:** The size of the outermost cube should be a parameter.
*   **Frame Width:**  The thickness of the frame for each cube needs to be adjustable.
*   **Rounded Edges:**  I'd like to have rounded edges on both the outer and inner parts of the frames.
*   **Base:** I need the option to include a base that sits under one of the corners, and this should have some configurable dimensions and a number of sides.
*   **Resolution:**  I'd like to control the resolution of the circles, I mean rounded edges, with a variable like `$fn`.

I think I need a couple of modules, something like this:

*   `rCube(x,y,z,rd,fn)`: For generating a rounded cube, which looks like it would be done with the `hull` function and translated spheres.
*   `cubeF(cs, ro, f_width)`: For making the cube frame using difference. This function would use the `rCube` module.
*   `cubeT(n)`: Would handle looping to generate the nested cubes, taking the number of cubes as input.
*   `stand()`: To create the base that supports the corner of the structure, making it stable.

I'd like to be able to set the size of the biggest cube, the width of the frame, the round radius of the outside, the round radius of the inner cuts, and the resolution for the round edges. Also, things like whether or not to show the base, the base size modifier, its thickness, diameter, and the number of sides.

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