I'm looking to design a WiiMote and Nunchuk holder, and I'd like it to be parametric in OpenSCAD. I've seen a design that's close, but it's designed to accommodate the silicone jacket, which I don't want. I'm looking for something that fits the bare WiiMote and Nunchuk.

Here's what I'm envisioning:

**General Layout:**

*   The holder should be able to accommodate a variable number of WiiMotes, from 1 to 4.
*   Each WiiMote should have its own individual slot/holder, so they aren't stacked or bumping into each other.
*   The Nunchuk should be held securely, with a place for the joystick to fit into, and should be positioned in front of the wiimote.
*   There needs to be a small cutout on the holder for the Nunchuk's cable to pass through.
*   I'd like to be able to choose whether or not to have mounting holes, with options for 0, 1 or 2 holes. If I choose 2 holes, they should be separated by a distance that I can specify.
*   I would like a version number stamped on the back of the holder

**Dimensions (these should all be parameters):**

*   WiiMote width (side to side): 37mm
*   WiiMote depth (front to back): 34mm
*   Height of the back of the holder: 50mm
*   Height of the Nunchuk joystick on the holder: 35mm
*   Thickness of the holder walls: 3mm
*   Thickness of the bottom of the holder: 3mm
*   Width of the front slot for the cable: 6mm
*   Size of the escutcheon for the Nunchuk: 26mm
*   Diameter of the top of the Nunchuk joystick: 16mm
*   Thickness of the top of the Nunchuk joystick: 4mm
*   Diameter of the Nunchuk joystick shaft: 12mm
*   Chamfer on the back corners of the Wiimote holder: 8mm
*   Chamfer on the front corners of the Wiimote holder: 2mm
*   Chamfering on the bottom edges of the Wiimote holder: 3mm
*   Chamfering around the Nunchuk escutcheon: 4mm

**Screw Hole Parameters (also parameters):**

*   The user should be able to choose between a counterbore or countersink.
*   Diameter of the screw holes: 5mm
*   For countersinks, the angle should be adjustable (60, 82, 90, 100, 110, or 120 degrees).
*   Depth of the countersink or bore: 2mm
*   Counterbore diameter: 9mm

**Stamp Parameters:**
*   The stamp will just be the version number of the print, and the user needs to specify the font, font size, and font thickness

**Other Design Details:**

*   The bottom of the holder should be scaled down slightly from the main body - I have parameters for scale_x and scale_y in my current code, and I think that's how it should be done here.
*   There needs to be a angled cut on the top part of the holder, it should start about 15mm back from the front of the holder, and be at 30 degrees.

I'd really like the code to be well-organized and easy to understand with comments. It would be great if you could generate all necessary files for this design including helper modules to make the code clean. I do not want to use any external libraries like BOSL or MCAD.

I'd like to design a customizable Christmas ornament bowl, kind of like a candy dish, but with a more ornament-like feel. I need two parts: the bowl itself and a connector piece that will fit into the top of the bowl, but also allow it to hang from a string or ribbon.

For the bowl, I want to be able to adjust the outer radius, how big the opening cut is, the wall thickness, the angle of a little shaft that will be connected to the top, and the position of that shaft along the bowl's circumference. I also want to control how much of the bowl is actually cut off at the bottom - the base part.

Specifically, I need these parameters to be adjustable:

*   `bowl_radius`: The outer radius of the bowl itself. I'd like to set a range for this, like between 50 and 130.
*   `open_cut`: This is the radius of the opening at the top. I need to adjust the diameter of this, so a range like 20-60 would work.
*   `wall`: This is the thickness of the bowl walls. A range of 1-5 should work.
*   `shaft_angle_correction`: This is the angle of the little cylinder that sticks out to be the mounting point, a range between 0-50 degrees will allow enough variation.
*   `shaftpos`: The position along the bowl's radius for where the shaft attaches. I'd like to set this to a range of 50 to 80.
* `cut_position`: The depth of the cut edge of the hole, like a chamfer, with a range of 0-15 would be ideal.

The connector piece needs to have a cylindrical base that fits into the hole at the top of the bowl, some sort of geometric array to add some form for decorative or structural use, and a smaller hanging ring on top. I'd also like to be able to switch between the bowl and the connector pieces when I'm viewing and printing the different parts.

Could you generate the OpenSCAD files for these parts? I'm not using any libraries, so I'd like a single, standalone .scad file for both parts. Please make sure that the code is well commented and easy to read.

I want to create a customizable hexagon monogram coaster that fits into the Two-Piece Stacking Hexagon Coaster design I found on Thingiverse. I need an OpenSCAD file that lets me specify three letters for the monogram. The first two letters should be from the standard alphabet, and the third letter should be from a special character set that's part of the Hex-ornate.otf font.

The code should allow me to choose between two font styles - a simple one called "Hex:style=monograms" and an ornate one called "Hex:style=ornate". These styles are also found within .otf font files. The .otf font files that I want to use are called "Hex-monograms.otf" and "Hex-ornate.otf". I'm not sure if it matters, but in the original code I was looking at it used $fn=50 for circle generation and a fudge factor of 0.02.

The final design should have a hexagonal base with a thickness of 1.5mm, and the monogram should be extruded to the same thickness and sit on top of it. I need to be able to adjust the letters used, the font style, and the overall thickness. I don't need to adjust the size or diameter of the overall hexagon. It should be the same size as the original Two-Piece Stacking Hexagon Coaster on Thingiverse (which has a diameter of 90 mm and an inner diameter of 87.22 mm, with a 30-degree rotation).

It would be great if you could also include a comment in the code that tells the user that they'll need to run the code locally as the Thingiverse customizer doesn't support custom fonts. Also, please make it a parametric design where I can change the font style, letter and extrude thickness.

I'm looking to create a customizable paint bottle stand for The Army Painter brand paints. I've got the bottle diameter (25.2mm), but I'd like a design that allows for a flexible number of rows and columns, and ideally, a staggered row option.

Here's what I'm imagining:

*   **Basic Structure:** The stand should consist of individual cylindrical holders for each bottle.
*   **Rows & Columns:** I want to be able to specify the number of rows and columns.
*   **Staggered Rows:** An option to stagger the rows, with a variable to choose if odd rows are short or long.
*   **Bottle Fit:** The bottles should sink into the holders to a specified depth (28mm), with some extra room. The bottle holder cylinders should have some degree of edge overlap to save on print material, the amount needs to be configurable.
*   **Tiered Design:** Each row should be a little higher than the one in front (25mm).
*   **Base:** The entire structure should sit on a base with a configurable height (3mm).
*   **Front Opening:** I need an opening in the front of each holder to see the paint label. This should be configurable by angle (90 degrees), and height (16mm, or the tier height, whichever is smaller). I'd like this opening to have some rounding.
*   **Material Savings:** I'm not too worried about this, but if the base could be more like a supporting structure than a solid block it might save time/plastic.

It would be fantastic if the design could also use OpenSCAD's `linear_extrude` and `rotate_extrude` functions for the opening, along with tori for rounded edges, because these generate nice surfaces for 3D printing. Also, please keep the design reasonably parametric, and use comments in the code. I’m assuming all of the code to do this will be created from scratch, including any helper modules. Let's start with the main module that calls the others, and then include the modules for the individual parts. I want to avoid any assumptions about the underlying library availability. This would include any libraries.

Oh, and since the bottles are round, the outer edges of the cylinder holding the bottles should also be round. I don't think it's necessary to add the small rounding to the inside of each cylinder, but the outsides should be nice and round.

I need to design a parametric faucet lever, and I'd like to use OpenSCAD. I have a basic concept I want to build on.

The design will have a cylindrical base with a socket for the faucet stem. The main part of the lever, or levers, will extend out from this base. I'd like the option to have either a single lever or dual levers extending from the base.

Here are the specific parameters I'd like to be able to control:

*   **Base:**
    *   `base_hi`: Height of the base cylinder.
    *   `base_dia`: Diameter of the base cylinder.
*   **Lever:**
    *   `lever_wid`: Width of each lever.
    *   `lever_leng`: Length of each lever.
*   **Socket:**
    *   `socket_dia`: Diameter of the socket hole.
    *  `socket_wid`: Width of the socket cutout.
*   **General:**
    *  `part`: Integer to select the type: 0 for a test socket, 1 for a single lever, and 2 for dual levers.
    *   `smooth`: Controls the smoothness of curves, using `$fn = smooth` (and should affect only the rounded sections)
    *   `i_tol`: Internal hole tolerance, for printing. This should be added to the `socket_dia`.
    *   `rounding`: Edge rounding value to be used on corners.

I'd like the levers and base to have rounded ends for comfort and aesthetics. It's also important that the socket be a bit larger than the `socket_dia` to account for printing tolerances, using the parameter `i_tol`. The socket should be a hole that's cut into the base cylinder. The socket cut out is basically a square with a width of `socket_wid` and depth that is equal to the diameter of the socket.

I'd like to have a single .scad file for this. Please use standard OpenSCAD syntax; I don't use any extra libraries.

I'd like to design a parametric egg holder for my refrigerator. I need it to hold at least two eggs side-by-side, and be easily tileable to hold more. I've got some measurements that I think should be adjustable to make this useful for a lot of folks, and also some parameters that make it a better fit for my specific situation.

First off, the key measurements I want to be able to control are:

*   `ws`: wall thickness (default 0.8mm)
*   `hd`: the area for a single egg, width, in mm (default should be `50-(4*ws)`) This is the width of an egg plus some wiggle room.
*   `ol`: overlap between eggs, in mm. (default `2*ws`). This will reduce the total width needed.
*   `ed1`: lower diameter of the egg cup, in mm (default 32mm)
*   `h1`: lower height of the egg cup, in mm (default 5mm)
*   `ed2`: upper diameter of the egg cup, in mm (default `48-(4*ws)`)
*   `h2`: upper height of the egg cup, in mm (default 18mm)

I'd like the egg cup itself to be a truncated cone, so that the egg is well supported, and then a small cylindrical section on the top of that. There needs to be a baseplate, and I'd like some "ears" on the sides to make it easier to pick up and move around - these should use a trapezoidal shape. The egg holders should be connected by a thin wall of material (thickness equal to `ws`). And, just for a bit of extra stability, a small cylindrical peg on the bottom of the baseplate, centered on the divider wall between the egg cups.

Finally, I'd also like the design to perform some error checking, in the module, and print to the console if any of these are true:

*   `ed1` > `ed2`
*   `h2` < 5
*   (`ed2` + 2 * `ws`) > `hd`
*   (`ed2` - `ed1`) / 2 > `h2`

I think that about covers it. I'd prefer if this were all in a single .scad file. No need to use any libraries here, I think. Thanks!

Hey, I'm looking for a parametric OpenSCAD design for a throttle slider mount, kind of like the one I found on Thingiverse (thing:3866960), but fully customizable to fit different potentiometer sizes. I also want it to be designed from scratch, not by modifying existing code.

Specifically, I need the mount to have adjustable parameters for:

*   **Slider Length:** The length of the slider potentiometer itself (in mm).
*   **Slider Width:** The width of the slider potentiometer (in mm).
*   **Slider Depth:** The depth/height of the slider potentiometer (in mm).
*   **Rod Diameter:** The diameter of the throttle rod that the mount will grip (in mm).
*   **Screw Diameter:** The diameter of the screws used to mount this whole fixture (in mm).
*   **Tolerance:** A printer tolerance value (in mm).

The design should basically have:
* a rectangular channel for the slider to fit into with a retaining slot (or several, for flexibility, it's up to you)
* a back wall
* a sort of faceplate at one end that also includes screw holes for mounting
* a hole for the throttle rod

I'd prefer the faceplate to have rounded corners for aesthetic reasons. It should be printable without supports, too. I'm not really particular about the default values for these parameters. I'm not really concerned about the connector or the limiting block; just the fixture itself. Oh yeah, and the hole for the rod should be located off to one side of the main body, and should go all the way through.

I'm not using any external libraries, but I know that you'll probably need the `hull()` command for rounded corners.

Could you generate the OpenSCAD code for this?

Okay, I'm looking to design a parametric coat hanger for 3D printing, and I'd like to be able to adjust quite a few parameters. I've been looking at some existing designs, and I've got a good idea of what I want. I want a design that is made of three main parts that press-fit together: two sides and a hook.

For the sides, I envision them being composed of a horizontal bar connected to a diagonal bar via a rounded corner. At the ends of the horizontal bar I want to have a pin-plate with pins that connect to the hook. The diagonal bar will have a corresponding pin-plate at its top, which also attaches to the hook. I want to specify the following parameters:

*   **`length`**: The overall length of the hanger, end-to-end.
*   **`height`**: The approximate height from the center of the horizontal bar to the top of the diagonal bar.
*   **`bar_d`**: The diameter of the bars that make up the hanger.
*   **`bend_d`**: The diameter of the bend connecting the horizontal and diagonal bars.
*   **`hook_d`**: The diameter of the hook.
*   **`hook_h`**: The total height of the hook, measured from the top of the diagonal to the top of the hook.
*  **`pin_offset`**: Distance of the pin on the side part from the corner.
*   **`overhang_angle`**: A setting for how much overhang my printer can handle, to ensure parts print smoothly, probably should default to 45 degrees.
*   **`pin_buffer`**: The space between pins on the pin plate.
*   **`tolerance`**:  A value to add to the diameters of the pins to ensure a tight press-fit.
*  **`$fn`**: facets parameter for the circle, default value of 32 should work.
*   **`Section_View`**: A boolean setting to enable or disable a section view for debugging purposes.
*  **`Section_X_Position`, `Section_Y_Position`, `Section_Z_Position`**: position parameters for the section view.

I'd like the parts to be joined together using a press fit, so I'll need to take into account how much spacing to add for that. I also want to be able to control the roundness of the bars, without impacting how it prints. The ends of the bars should be flat rather than completely round (as in a full cylinder). Ideally, this should be done by creating a trapezoidal wedge that is fit into the circular profile. The crossbeam in the hanger should be strong and stable.

The pins on the pin plates should be cylindrical with a bit of a spline to aid press fit, and have mating holes on the hook. I'd also like to have an optional clothespin-like clip that can be added to the side of the hanger for holding clothes, like what is done in version 2.2 of the original code. I want to be able to control whether or not the clip exists via a parameter.

I think that's all, please let me know if you have any questions!

I need a custom wall mount for my quadcopter drones, and I'd like it to be parametric so I can easily adjust it for different models. It should have two main supports that cradle the drone's arms and a way to mount it to the wall.

Here are the basic parameters I'm thinking of:

*   `quadSupportDistance`: The distance between the two supports, where the drone arms will rest.
*   `quadFrameThickness`: The thickness of the quad's frame. This will help determine how far the supports protrude to cradle the arms securely.
*   `screwHoleWidth`: The diameter of the mounting hole for the screw that will attach the mount to the wall.
*   `bevel`:  The size of the bevel on the corner.
*   `thickness`: The overall thickness of the mount.

The design should have a sort of "hook" on each support to hold the arm, and it should be fairly simple to print. The main body of the mount can be a modified triangle with the support hooks at the ends. I'm also thinking the main body triangle will have a cutout so it uses less material.

Could you generate an OpenSCAD file for this, using these parameters? I'd like to be able to modify these and re-render it. I don't need any special libraries, just the basics.

I'd like to design a customizable cable tie in OpenSCAD, and I need your help creating the code. I've seen a few designs, but I want to be able to control several key aspects.

First off, the main part of the cable tie will be the flexible, zig-zagged strip. I need to be able to set the length of this zig-zag section, as well as its width and overall thickness. The thickness should be something thin, probably around two layers when 3D printed, so it remains flexible.

Then there's the head of the cable tie, where it locks into place. I'd like to be able to choose between an angular or rounded head shape. A crucial feature I need is the option to create two slots within the head, allowing it to be more permanently attached to a cable. It's important this is controlled by a parameter.

Finally, the head should allow for some space for labels, either to write on or to emboss text into. This should also be parametric so that I can increase the size of the label area. I need to be able to specify the text and font used for these labels.

So, to summarize, I need a parametric OpenSCAD design for a cable tie with the following features:

*   **Zig-zag strip:**
    *   `length`: Adjustable length of the zig-zag section.
    *   `width`: Adjustable width of the zig-zag section.
    *   `thickness`: Adjustable thickness of the entire cable tie (should be thin for flexibility).
*   **Head:**
    *   `doubleSlots`: Boolean parameter to enable/disable two locking slots.
    *   `roundHead`: Boolean parameter to switch between rounded or angular head shape.
    *   `labelLength`: Additional length to add to the head for labeling space.
*   **Label:**
    *   `labelText`: Text to be included on the label.
    *   `labelFont`: Font used for the label text.

I think it should be possible to achieve this without using any external libraries. Please provide the OpenSCAD code for this.

Hi! I'm looking to create some customizable stitch markers for knitting/crochet using OpenSCAD. I saw a file online, and I'd like something similar, but I want a parametric design that I can easily adjust.

Here's the basic idea:

*   **Shape:** The main body should be a disc with a slot cut out of it.
*   **Clip:** There needs to be a small, partial circle that connects to the main disc to act as a clip. It shouldn't close completely around the disc.
*   **Parameterization:** I'd like to control the following:
    *   Number of rows and columns of markers to generate.
    *   Outer diameter of the marker.
    *   Height/thickness of the marker.
    *   Thickness of the "clip" part.
    *   Width of the slot opening
    *   Spacing between markers.
*   **Functionality:** The design should be such that the clip part can open enough to clip onto a yarn strand but will not disconnect easily. The slot should have enough width to allow for easy insertion and removal of yarn but not so much that the marker easily falls off.
*   **Libraries:** I'd like to avoid using any external libraries if possible, so vanilla OpenSCAD is fine.

Could you generate an OpenSCAD file that implements this?

[Assistant]
marker.scad:
```

// number of rows of markers to generate
rows = 3;
// number of columns of markers to generate. Total number of markers generate = rows * cols
cols = 2;

// outer diameter of marker (mm)
outer_diameter = 15;

// height of marker (mm)
height = 2;   // height

// thickness of marker (mm). Use a multiple of nozzle width.
thickness  = 1.6;

// width of the slot (mm)
slot_width = 2; // slot width

spacing = outer_diameter * 1.5;

for(ox=[0:spacing:spacing * rows - 1],
    oy=[0:spacing:spacing * cols - 1]) {

    translate([ox, oy, 0]) {
        union() {
            difference() {
                cylinder(d=outer_diameter, h=height);
                translate([0,0,-1]) { // extend for clean cut
                    cylinder(d=outer_diameter - 2*thickness, h=height+2);
                    translate([0, thickness - outer_diameter/2, 0]) {
                        cube([outer_diameter, slot_width, height+2]);
                    }
                }
            }
            translate([0, - outer_diameter/2, 0]) {
                cube([outer_diameter/2, thickness, height]);
            }
            translate([outer_diameter/2, thickness/2 - outer_diameter/2, 0]) {
                cylinder(d=thickness, h=height, $fs=1);
            }
        }
    }

I'd like to create a customizable screw box, similar to the one described in the thingiverse links (662476 and 582221) and the github link. The key thing is it needs to be parametric so I can adjust the dimensions.

Here's what I need to be able to control:

*   **Overall Design:** The box will consist of two pieces that screw together, using a spiral finger design.
*   **Fingers:**
    *   The number of "fingers" in the spiral should be adjustable.
    *   The inclination of the spiral fingers should be adjustable via a factor.
*   **Dimensions:**
    *   The inside diameter of the box.
    *   The inside height of the box.
    *   The minimum wall thickness.
    *   An extra thickness at the bottom (so the bottom is a bit thicker and easier to rotate the pieces).
*   **Part Coverage:**
    *   I need to be able to set what percentage of the inside box height each of the two halves covers. They should sum to less than 100% so there's a little bit of tolerance, and for example one half could cover 48% and the other 48%, or one could cover 13% and the other 83%.
*   **Tolerances:**
    *   There should be a tolerance setting (in mm) to account for printer imperfections.
    *   There should also be a tolerance for the angle between the spiral parts so they fit smoothly.
*  **Resolution**
    * A $fn setting should control the resolution of the circular and curved parts.

I'd like to be able to configure these parameters and generate the two pieces of the screw box as separate STL files. I'm not looking to use any external libraries for this.

Hey, I'd like to design a quickdraw/gear holder that I can clip onto a bag. I'm envisioning something similar to the provided example, but with a few important changes, and the ability to change a whole lot more about the design.

First, I need the main body to be a sort of flattened cylinder, but with customizable radius, thickness, and a customizable number of gear slots that are evenly spaced along the circumference. Each slot should be able to hold a quickdraw or similar piece of gear. These slots should be roughly rectangular in shape, but with rounded ends for smoothness, and the ability to control the dimensions of the slot.

Second, I'd like a customizable text label on the front. Just like in the provided example, I need to be able to control the string, font, and size. This text should be raised so that it's easy to read. It should be centered along the flattened face of the cylinder.

Third, I want a customizable clip that attaches to the back of the flattened cylinder. This clip needs to be designed to fit various sized straps, like those you would find on a backpack, and I'd like control over how it mounts (e.g., does it attach flat, at an angle, etc). The clip should also be parametric such that I can change the thickness of the clip, the length, and the angle that it curves at to hook onto a strap.

Finally, I need everything to be parametric. So, I need to control things like the number of gear slots, the size of each slot, the overall diameter and thickness of the main body, the text label, and the dimensions of the clip. I'd also like it all to be driven from a single main file. I don't need complex features, so no libraries are required for this design, it should be accomplishable with only built in primitives in OpenSCAD.

Can you generate an OpenSCAD file that can do this?

I'd like to design a parametric storage container for rolls of bags, like the ones you get in the grocery store produce section. I have an existing SCAD file that I've used, but I want a new one with more configurability and cleaner code.

The basic shape is a half-cylinder with a back wall that extends out from the flat side to allow for mounting. The key parameters should be:

*   `dia`: The outer diameter of the cylindrical portion. This determines the overall width of the storage area.
*   `hgt`: The thickness of the reinforcing rim around the opening and at the back.
*   `oh`: The overall height of the container.
*  `wall_thickness`: The thickness of the cylindrical wall.
*   `mounting_hole_dia`: The diameter of the mounting holes on the back panel.
*  `mounting_hole_spacing`: The vertical distance between the mounting holes.
*   `num_mounting_holes`: the number of mounting holes.
*   `hex_pattern_radius`: The radius of the hexagons in the base pattern.
*  `hex_pattern_wall_thickness`: The wall thickness between the hexagons in the base pattern.
*   `base_thickness`: The thickness of the base of the container.
*   `top_rim_height`: The height of the small rim at the top of the container.
*   `top_rim_inset`: The amount to inset the rim at the top compared to the outer diameter.
*   `top_rim_chamfer`: The angle/distance of the chamfer on the top rim.

I need it to have a base with a hexagonal pattern cut into it to save on material. The cylindrical portion should have a reinforcing rim at both the top and the bottom, and there should be a small chamfer at the top edge. The back wall should have mounting holes.

I would like the design to use the `BOSL` library for any mathematical operations or geometric constructions it makes sense to use. I also want all parameters to be explicitly named and configurable at the top of the file and the code to be well-commented. I think that should be all.

I'm looking to create a customizable, stackable game counter, similar to the one I found on GitHub, but I want to be able to generate it using OpenSCAD. The core idea is a cylindrical or slightly deformed shape with text engraved on top, and a design that allows multiple counters to stack on top of each other.

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

*   **Marker Dimensions:**
    *   `diameter`: The overall diameter of the marker (in mm).
    *   `height`: The overall height of the marker (in mm).

*   **Marker Shape:**
    *   `sides`: The number of sides to use for creating the base shape. A high value should result in a circle. This should support a range of at least 4 to 150.
    *   `rotation`: The rotation of the base shape (in degrees), for aligning text correctly.
    *   `deformation`: A factor to scale the shape in one axis, this should give me the ability to create rectangularish markers and not only perfect circular ones.

*   **Text:**
    *   `text`: The text to be engraved on the top of the marker.
    *  `text_size`: The size of the text.
    *   `text_spacing`: The spacing between letters in the text.

*   **Printer Settings:**
    *   `tolerance`: A tolerance value (in mm) to account for printer inaccuracies when creating the stackable parts.

*   **Other:**
    *   `fn`: Resolution setting for circles and curves.

The design should be a solid base with a recess or lip on top so that another marker can sit on it. I need a main module called `marker_text` that uses the parameters for marker shape and text to create the final counter. This `marker_text` module should internally use another two modules called `marker_base` and `marker`, and also an `etruded_text` module for the text. I'd also like the text to be slightly inset into the base.

Could you generate the OpenSCAD code for this? It would be great if you could include comments to explain the different parts. No need for any external libraries.
