I'm looking to create a decorative Christmas ball with a specific spiral pattern based on the Fibonacci sequence. I've seen examples online, and I'd like to replicate that design in OpenSCAD.

The core concept is a spherical base with a series of cone-like protrusions arranged in spirals that follow the Fibonacci pattern. The spirals should originate from a central point, similar to what you'd see on a pinecone or sunflower.

Here are the parameters I'm thinking of, and I'd like to be able to adjust these easily:

*   **`ball_size`:** The radius of the main sphere.
*   **`spheres_size`:** The radius of the base of the cone protrusions.
*   **`twist_factor`:** A multiplier controlling the overall twist/rotation of the spirals. This determines how rapidly the spirals wrap around the sphere.
*   **`fixation_position`:** The distance from the center of the sphere along the Z-axis where I want to add a connection for a hanging mechanism.
*   **`fixation_size`:** The size/radius of the connection mechanism for the hanging part.
*   **Number of Protrusions**: I’d like to control the total number of protrusions used, as this is related to the overall Fibonacci spiral pattern. This is probably related to how many times we iterate around the ball, so a user-specified parameter for that would also be useful.
*   **Protrusion Shape**: Rather than simple cones, I’d like the protrusions to be truncated cones, so the actual point is flat.

I'm envisioning the protrusions as truncated cones, rather than full cones, with the base of the cone attached to the sphere.

I'd like the code to be parameterized, so I can adjust all these values without having to dig into the geometry calculations, and I'm not looking to use any external libraries for this design. I'd also like a version of the design that is only the Fibonacci pattern itself, without the hanging mechanism, to let me experiment with the pattern without the fixation getting in the way.

{
	difference()
	{
		sphere(size);
        translate([0,0,-size]) cube(2*size,center=true);
	}
}

	for (i = [-150:164])
		rotate([0,0,i*twist_factor/PHI])
			rotate([exp(i/120)*45,0,0])
				translate([0,0,ball_size])
					cylinder(
						h=spheres_size/2,

						r2=0
					);

I'd like to design a parametric pegboard hook system using OpenSCAD. I need a few different types of hooks:

*   **L-shaped hook:** A basic L-shape that extends out from the pegboard.
*   **Round hook:** A simple rounded hook, like a half-circle or "J" shape.
*   **Supported round hook:** Same as the round hook, but with an extra support arm underneath.
*   **U-shaped hook:** A U-shaped hook.

I'd like the following parameters, with defaults that I'll list in parenthesis:

**Peg Type Parameters:**
*   `peg_item`: (String, "U") Type of peg to generate, should accept "L" for L-shape, "R" for round, "B" for supported round, "U" for U-shape.
*   `end_arm_percentage`: (Integer, 25) For U-shape hooks, the length of the upright arm, as a percentage of `peg_length`. Should be between 10 and 100.
*   `peg_length`: (Integer, 20) Length of the hook extending from the pegboard. Should be between 20 and 80.
*   `add_shelf_support`: (String, "N") Whether to add a support arm for L, U, or supported round hooks.  Should be "Y" or "N".
*   `hook_width_percentage`: (Integer, 100) How wide the hook should be in relation to the peg hole size. Should be between 60 and 100.  This would determine the width of the bar stock used to create the hook.
*  `drop_bottom_arm`: (Integer, 0) How much to drop the bottom arm of the peg, if the arm is meant to sit below the peg. Should be between 0 and 20.

**Pegboard Parameters:**
*   `hole_size`: (Integer, 7) Diameter of the peg holes in the pegboard. Should be between 1 and 10.
*   `tolerance`: (Integer, 5) Tolerance for the peg fit.  Higher numbers for softer material. Should be between 1 and 10.
*   `backing_board`: (Integer, 6) Thickness of the pegboard backing. Should be between 1 and 20.
*   `peg_offset`: (Integer, 25) Distance between peg holes (center to center). Should be between 20 and 40.

I also need a module for generating the peg that fits into the pegboard, call it `fit_peg()`.

For the support arm, could you use an angled arm? In other words, instead of using an upright arm to support the main hook (in the case of supported hook styles), could you use one that is roughly 45 degrees?

The peg designs should be parametric so that if the parameters are changed, the design adjusts accordingly.

Please make sure to include clear comments in the code explaining what each section does and also make sure that the code is properly formatted and indented.

I don't need to use any external libraries for this design, so just native OpenSCAD features would be great.

I'd like to design a parametric toggle switch in OpenSCAD. I want it to be pretty flexible in terms of dimensions and mounting options. I've got a basic idea of what I need, and I'll try to break it down into manageable parts.

First, the base of the switch should be a rectangular prism. Let's call the dimensions `bX`, `bY`, and `bZ`. These should be parameters. I'd like it to be centered at the origin.

Next, there are the terminal tabs. There will be three tabs, located on the bottom of the base. One should be in the center, and the other two should be symmetrically on either side along the x-axis. I would like to be able to use these as connection points. Each tab should be a small rectangular prism with dimensions `tabX`, `tabY`, and `tabZ`. The positions of these tabs should be parametrically controlled, using `centerX`, `centerY`, `endX` and `endY`. It should be mirrored across the z axis.

The toggle itself should start as a cylinder that goes up into the base. The top of this cylinder becomes the bottom of a second, angled, truncated cone. A small sphere is attached to the top of this truncated cone. The diameter of the initial cylinder should be `tgDia1` and the top of the truncated cone should be `tgDia2`. The total length of the cone and final sphere (without the base cylinder) should be `tgZ`. It should start at `screwZ` above the base of the cylinder, and be tilted at a `swAngle`. I want it all together to look like a single object. I am not sure how to make the connection points yet. The bottom cylinder's height should be equal to `screwZ`.

There will be two mounting nuts on top of the base. The nuts should be hex nuts, and I'd like to be able to specify their dimensions. The distance across the flats should be `nutFlat` and the thickness should be `nutThick`. I should be able to specify the height of the bottom nut (`nut1H`) relative to the top of the base. The height of the top nut above the bottom nut should be `nut2H`.

Finally, I want a `switch()` module that can assemble all of these elements. I would like an optional parameter `center`. If it is set to `"body"` (the default), the assembly should be centered with respect to the base. If set to `"nut"`, the assembly should be centered on the top of the first nut. This allows the switch to sit directly on a surface or have a nut underneath.

Could you generate this as one or more OpenSCAD files? I don't need any of the MCAD or other libraries.

I'd like to create a shelf talker, basically a vertical label holder for a retail shelf. I have some ideas from looking at a few designs on Thingiverse, but I'd like something parametric and built from scratch.

The basic concept is this: There will be a vertical plate that displays text, and then a bracket that mounts onto the shelf to hold the plate. The plate will have raised lettering so I can print in two colors. The bracket will clip onto the shelf itself.

Here's the breakdown of what I need:

**Text Plate:**

*   **Text:** The text should be customizable. I should be able to enter any text string.
*   **Font:** I need the ability to choose different fonts, ideally from a selection. I’d also like to be able to control the size of the font.
*   **Dimensions:** The plate should fit snugly into the bracket. The overall length of the plate should be determined by the length of the text, width should be parametric, and thickness should be controllable.
*   **Lettering:** The letters will need to be raised from the plate by a bit so that they stand out. There needs to be adjustable spacing between the letters.

**Bracket:**

*   **Shelf Thickness:** The bracket must be parametric and adjust to different shelf thicknesses, or have a range of sizes.
*   **Mounting:** The bracket should clip onto the shelf securely, possibly with an angled lip to hold it in place.
*   **Holder:** The bracket needs a slot or channel to hold the text plate. It should provide clearance, but hold the plate firmly.
*   **Dimensions:** The dimensions of the holder slot should be adjustable to accommodate for different plate thicknesses.

**Overall:**

*   **Parametric Design:** Everything should be parametric, so I can adjust sizes and dimensions easily. I'm looking for all dimensions to be controlled as parameters.
*   **Libraries:** I would like you to use the Write.scad library to generate the text. Please include build_plate.scad to generate the build plate.
*   **Two-Color Printing:** The design should be suitable for two-color printing where the main body is printed in one color and the lettering in another. This might require an offset in the z-axis when printing the lettering.
*   **Units:** I'd like all dimensions to be in millimeters.

I think that covers everything. Could you help me build this?

I need a parametric OpenSCAD design for a cooling fan holder that attaches to the left side of a Makerfarm Prusa i3v extruder. The holder needs to support a fan that will blow air towards the workpiece to cool it during printing.

Here are the key parameters:

*   **Fan Angle:** The fan should be angled downwards towards the workpiece. This angle should be adjustable with a default of 35 degrees (and a reasonable range of say, 15-45 degrees).
*   **Base Attachment:** The bracket attaches to the extruder with a single screw. I need a hole for an M3 screw (3.3mm diameter) with a sink for the screw head. The hole should be slightly slotted vertically to allow for some play (1mm in either direction). The sink should have a diameter of 9mm and a depth sufficient for a standard M3 screw head, leaving about 4mm of material for the screw thread. The horizontal position of this hole should also be configurable.
*   **Fan Mounting:** The fan is mounted with two M3 screws. The holes for these screws should be perpendicular to the angled surface of the bracket, with a center-to-center distance of 32mm. The horizontal offset of the holes should also be adjustable. The diameter of the screw holes is 2.5mm.
*  **Fan Vent:** There should be a large, round cut-out on the sloped face for air flow. This cut-out should be perpendicular to the surface of the slope with a diameter of 35mm. The horizontal position of this should be configurable, perhaps based off the fan mounting holes position.
*   **Overall Dimensions:** The base of the bracket should have adjustable length, width and height. The side wall should be 12mm thick at the base of the slope. The top of the base should be 3mm thick. The overall height should be about 10 mm greater than the top thickness.

I'd like the design to use a solid base with a cut out section forming an L-shape. The fan angle cut should be generated using a subtraction, and the fan screw holes and the fan vent should also be cut from the solid. I'd prefer to work with solid parts and subtraction rather than creating the bracket with polygons and extrudes. Also, for debugging purposes a debug parameter that reduces the render quality for quick testing would be great. I'd also appreciate if the final output was oriented for printing, that is rotated such that it's flat on the print bed. The design should avoid using any external libraries.

Can you generate the OpenSCAD file(s) for this?

I'd like a cable catcher design, something that clips onto the edge of a desk to prevent cables from falling behind it. I need it to be parametric so I can easily adjust the design for different desk thicknesses and the number of cables I want to manage.

Specifically, I envision a design with a main body that clamps onto the desk edge. This body should have a flat, horizontal top surface and a vertical face that rests against the edge of the desk. There needs to be a sort of lip or flange at the bottom of the vertical face that hooks under the desk to securely grip it. The main body would also need to have multiple semi-circular or u-shaped cutouts along its top surface that allow individual cables to pass through. These should be equally spaced apart, with the overall width of the catcher and the number of cutouts being configurable. I'd also like some kind of support structure at the rear to help with holding the cables. Something like a wall with some holes or cutouts for zip ties maybe.

The design should be in OpenSCAD. I don’t have any libraries set up other than the standard OpenSCAD modules, so please make sure to use only modules provided by that standard library.

I think that's about it for now, let me know if I need to clarify anything!

I'm looking to create a design that resembles a section of a vinyl record, but much larger. I'd like it to have a defined groove that wraps around the circular section. It should also have some elements that look a bit like a soundwave pattern around the central vinyl section.

Here are the key things I'm envisioning:

*   **Vinyl Record Section:**
    *   It should be a rectangular piece, with configurable width, depth, and height in millimeters.
    *   The groove should be cut into one of the flat faces.
    *   The distance between the bottom of the section and the start of the groove should be adjustable.
    *   The groove should be made of a series of connected slices that use the `hull` operation to create a smooth, continuous groove.
    *   The slices should be generated around a line that can be shifted and rotated sinusoidally, which is what gives the groove a realistic curve to it.
    *   The number of faces of the groove should be adjustable, which controls the smoothness of the curve.
*   **Soundwave Decorations:**
    *   Around the central vinyl section, I want to include several soundwave-like decorations.
    *   These should be generated from a 2D shape that is extruded and differenced with other shapes to give it a 3D form.
    *   The height of these decorations should also be adjustable.

I'd like to control these parameters:

*   `width`: The width/depth of the vinyl record section in mm.
*   `height`: The thickness of the vinyl record section in mm.
*   `faces`: The number of faces for the groove.
*   `grooveheight`: The distance between the bottom of the section and the groove in mm.
*   `shift_freq`, `shift_phase`, `rot_freq`: The frequency, phase, and rotation frequency for the groove.
*   `decoration_height`: The height of the soundwave decorations in mm.

I'd like the design to be parametric so that I can easily adjust these values. Can you generate a parametric OpenSCAD file for this? I'm not looking to import any pre-existing libraries for this.

[User]
I'd like to create a parametric, hinged sign that I can customize with my own text. The sign should be designed so that it prints flat, fully assembled, without any supports, and the text is only readable after it's folded. I'd like to be able to specify the height of the panels, the number of characters in the word or phrase, and then enter each character (including spaces) individually. It needs to be hinged and the hinge has to have a specified radius and clearance.

I'd also like to control some of the other parameters, like a 'mysterious thickness parameter' that's mentioned in the code, and the amount of clearance space for stacking between the panels. The code includes a stacking clearance, a rounded corner radius, and other variables related to panel and hinge construction. Basically, I need the ability to adjust the various physical characteristics of the sign and the hinges.

The existing code uses the `write/Write.scad` library, so please make sure to include that in the design. The basic idea is that each character is on a separate panel, and they are hinged together. The first and last panels need to have some differences in the hinge design, as they will only have one hinge. I need to be able to specify the text and have it appear on each panel.

Could you generate an OpenSCAD file (or files) that does all of that?

Hey there! I'm looking to create a parametric model of an E3D-v6 All Metal HotEnd in OpenSCAD. I've seen a few versions out there, but I want something I can easily tweak for different nozzle sizes, heater block dimensions, and potentially even different heatsink profiles.

The basic structure should follow the standard E3D-v6 design: a cylindrical heatsink, a threaded heatbreak, a heater block, and a nozzle. I'd like to be able to adjust the following parameters:

*   **Heatsink:**
    *   Overall height
    *   Base diameter
    *   Top diameter
    *   Number of fins (if possible, with fin height and thickness parameters)
    *   Heatsink bore diameter
*   **Heatbreak:**
    *   Threaded length (both ends)
    *   Total length
    *   Minimum inner diameter
    *   Outer diameter
    *   Thread pitch
*   **Heater Block:**
    *   Length, width, and height
    *   Nozzle thread hole diameter and thread pitch.
    *   Heatbreak thread hole diameter and thread pitch
    *   Thermistor/Cartridge heater bore diameter
    *   Set screw hole diameter
*   **Nozzle:**
    *   Overall length
    *   Threaded length and diameter (to match the heater block)
    *   Tip diameter
    *   Inner diameter (bore)

I'd also like to be able to toggle the inclusion of mounting features like the groove mount or the block clamp for the heater block. I'm hoping for a design that is clean and easy to modify in the future, and I would like all dimensions to be controlled by variables at the top of the file, with clear comments.

I'm not too concerned about visual detail beyond a good basic representation - I'm mostly concerned about accurate sizing and proportions.

I would prefer the core functionality be built using built-in OpenSCAD functions, and I'd like it to be modular, breaking the design into separate modules for the heatsink, heatbreak, heater block and nozzle.

Could you help me generate an OpenSCAD file (or set of files) with these parameters and modules?

Hey, I've been making some molds for Oogoo balls and I'm looking to create a more customizable version of what I've got. Basically, I'd like to be able to easily change the ball size, mold thickness, and have an option for either a single-part or two-part mold.

The basic idea is to create a spherical mold. For a two-part mold, you would essentially create a sphere, cut it in half and subtract a smaller sphere from each half, leaving a void for the Oogoo to be poured into. The mold should have some thickness to it. My current script uses a cylinder to support the mold, which could probably be done with a cube and a couple of translates.

I'd like the following parameters:

*   `ball_diameter`: The diameter of the final Oogoo ball.
*   `mold_thickness`: The thickness of the mold material.
*   `mold_type`: An option to select either "single" for a single piece mold or "two-part" for a mold that comes in two halves.
*   `$fn`: Resolution for the sphere and other curved surfaces.

So, the output should be either a single mold or two halves depending on the `mold_type`. I'd also like to have the ability to change the resolution `$fn` globally. I'm pretty new to OpenSCAD and not sure if MCAD would be useful. I think I'll just try to define all of the shapes natively, but if you know of a good MCAD function for a sphere, then feel free to use that.

Can you help me put this together in OpenSCAD?

I'm looking to create a parametric heart-shaped cookie cutter using OpenSCAD. I need to be able to adjust several parameters to get the exact shape and size I need.

Specifically, I need the following adjustable parameters:

*   **Overall Dimensions:**
    *   `width`: The width of the heart shape.
    *   `length`: The length of the heart shape.
    *   `height`: The total height of the cutter (including the blade and any base).
*   **Blade Parameters:**
    *   `wall_thickness`: The thickness of the cutting blade.
    *   `cutting_angle`: The angle of the blade's cutting edge.
*   **Base Parameters:**
    *   `base_width`: The width of the base of the cutter.
    *   `base_height`: The height of the base of the cutter.

The cutter should have a heart shape and be created by using a minkowski sum of cylinders and a polygon for the body, and have a blade that tapers to a cutting edge using the provided angle. I'd also like a base at the top of the cutter for added strength and comfort, with adjustable width and height. Please generate the necessary OpenSCAD file(s) to achieve this, and make sure to include comments explaining what the different parts of the code do. I'm not using any libraries.

I need an OpenSCAD design for a customizable, rounded-corner box, with an optional cover. I'd like to be able to specify the external length, width, and height of the box (without the cover), as well as the wall and bottom thickness. The corners of the box should be rounded, with a customizable radius.

The cover should also have rounded corners matching the base and should fit snugly over the base, with a small clearance between the box walls and the cover. I need to specify the external and internal height of the cover, the cover's thickness, the margin for clearance between the base and cover, and the thickness of the cover's walls. It would be nice if the cover could be offset on the Y axis for printing both parts at the same time.

I'd like a parameter to select whether I want to generate the base only, the cover only, or both the base and cover.

Could you generate the OpenSCAD code for this? I don't need any particular libraries besides OpenSCAD standard functions.

[User]
I'm looking to create a customizable vinyl record cleaner, and I've seen a really cool design that I'd like to use as a base. I need it to be parametric so I can tweak it.

Here's what I'm thinking:

*   **Overall Shape:** The cleaner should have a long, rectangular body with rounded ends. Imagine a long, slightly flattened cylinder shape. The main body needs to have a handle portion, kind of like a wider flat bit on the bottom, that the user can grip and run over the record.

*   **Dimensions:**  I'd like to control the overall length, width, and height, as well as the radius of the rounded ends. The "handle" portion should be a flat rectangle extending along most of the length of the cleaner, and I need to control that height too. I'll need the height of that handle portion, and a "notch" that affects how wide it is.

*   **Optional Hole:** I want to optionally be able to include a hole through the main body to save on print material. This hole would need to be made up of two cylinders which are then 'hulled' into one, like a kind of capsule shape. I also need a way to set the position and radius of this hole. The position should be a relative offset in the x and y.

*   **Label Options:** I'd like a few options for the top face:

    *   **No Label:** Just a clean surface.
    *   **Text Label:** Two lines of customizable text. I should be able to set the text, the font, the height, the thickness, and a general position for both lines of text. I want to use a different font than the default one so I'll need to include the write.scad library, and I'll need to be able to select from fonts included in that library, like "orbitron.dxf", "BlackRose.dxf", "Knewave.dxf".
    *  **Ghost Vinyl Logo:** I need to optionally put the Ghostly International logo (like the thing on their website, I think it looks like a ghost) on the back.  I understand I need to use a function that draws the ghost from a set of points so that would need to be included.

*   **Plate:** It should also include a thin rectangular base (or plate) that I can glue fabric onto to do the actual cleaning. I need to control the width and length of the base, as well as its thickness and how much of an offset it has relative to the main body. It also has a rounded end shape that needs to be controlled via a radius variable.

*   **Color:** It would be helpful to have the main body be white and the text/logo be black by default, but this isn't critical.

Essentially, I want a highly customizable record cleaner that I can adjust to suit my needs, but has a general shape as I described. I'd like all of this controlled through variables at the beginning of the file. I need to use the `write.scad` library for the text functionality, and the ghost logo needs to be included as a module, too.

Could you please generate this parametric OpenSCAD file for me?

I'd like to design a parametric cable holder, similar to the one I've got here, but I want to make it more flexible and easier to customize.

The core idea is a series of "holder units" sitting on a base. Each holder unit should consist of two sets of teeth that can grip the cable. These teeth are like small rounded triangles, with a gap between each set for the cable to pass through.

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

*   **`cable_width`**: The spacing between the two sets of teeth in a holder. This is the width of the gap for the cable.
*   **`cable_holder_thickness`**: The thickness of the material that makes up the holder unit.
*   **`tooth_depth`**: The depth of a single tooth in each set of teeth.
*   **`number_of_teeth`**: The number of teeth in each set of teeth in a holder.
*   **`number_of_holders`**: The number of holder units on the base.
*   **`holder_spacing`**: The distance between each holder unit on the base.
*   **`base_thickness`**: The thickness of the base on which the holders sit.
*   **`base_height`**: The height of the base on which the holders sit.

I'd like to be able to specify all these parameters and have the OpenSCAD generate the complete design. The base should be a rectangular prism. The teeth themselves should be cylinders rotated to give a triangular look. I'd also like to add two small cylinders on the base, below each holder, to allow for screws. The screw holes should also be parameterized, so I can change their radius (`screw_radius`) without issue.

Essentially, I'm aiming for a fully parametric design that allows me to easily adjust the number of holders, the size of the cable gaps, and the overall dimensions. It would be great if this could be accomplished in a single .scad file. I'm not using any libraries so it'll just need to use basic OpenSCAD commands.

Hey, I'm working on a shovel handle design and I'd like to generate a parametric model in OpenSCAD. I've got a specific shape in mind that involves a cylindrical overlap section for the shovel handle, a curved connecting section, and a grip portion.

Here's the breakdown of the parameters I want to control:

**Overall Dimensions:**

*   `O_Length`: Length of the overlap section that goes onto the existing shovel handle.
*   `In_Dia`: Inner diameter of the overlap section.
*   `Out_Dia`: Outer diameter of the overlap section.
*   `S_Length`: Length from the start of the overlap section to the center of the grip.
*   `G_Dia`: Diameter of the grip portion.
*   `G_Length`: Length of the grip portion.
*  `trim`: A length to trim off excess material.

**Mounting Holes (up to 3):**

*   For each hole (Hole 1, Hole 2, Hole 3) I'd like to be able to define:
    *   `H#_Dia`: Diameter of the hole.
    *   `H#_X`: X coordinate of the hole center relative to the origin (center of overlap).
    *   `H#_Y`: Y coordinate of the hole center relative to the origin.
    *   `H#_Z`: Z coordinate of the hole center relative to the origin.
    *   `H#_Xrot`: X rotation of the hole.
    *   `H#_Yrot`: Y rotation of the hole.
    *   `H#_Zrot`: Z rotation of the hole.

**Additional Notes:**

*   The transition between the overlap section and the grip should be a smooth curve. Use two cylinders joined at the same starting point and a shared length for that curvature.
*   The holes should go entirely through the overlap section.
*   I’d like the design to be easily customizable, so using modules and variables is great.
*   I'd like a "cap" on the end of the overlap portion.

Could you generate an OpenSCAD file or files to handle this?
