Okay, I'm looking to design a custom pet collar, and I'd like it to be fully parametric so I can easily adjust it for different sized pets.

Here's what I'm envisioning:

The collar should be essentially a ring with a flat profile, designed to be 3D printed. I need to be able to specify the following parameters:

*   **`collar_id`**: This will be a text string that gets printed onto the *outside* surface of the collar. It could be anything – the pet's name, my address, phone number, whatever I need.
*   **`collar_radius`**: The approximate radius of the collar, roughly corresponding to the pet's neck. This should be a number, and I'll need to add some slack to that number for comfort and easy fastening.
*   **`collar_width`**: How wide the collar band is, from the inside to the outside edge.
*   **`collar_thickness`**: The overall thickness of the collar (how tall the cross section is).
*   **`break_thickness`**: I want a small gap in the ring to allow the collar to bend open a little to be placed around the pet's neck; this is how thick that little section should be.
*  **`catch_angle`**: How much the end of the collar will extend to form the catch.
*  **`catch_width`**: How far the catch will stick out from the main collar section.

The collar should have a sort of "catch" or overlapping tab to make it a little more secure (or at least appear so). I want a small section of the ring to extend out to make the two ends overlap. The catch should be on the inside of the collar, overlapping the other side.

The text should be printed so that it is perpendicular to the radius of the collar. And of course it should all be generated parametrically in OpenSCAD so that changing the values adjusts the whole thing easily. I would prefer if the text and ring were all one single object, rather than requiring a separate step.

I'd need the code for a `pet_collar.scad` file, and since you'll need text functionality, also any files needed to support that text generation, particularly a `write/Write.scad` file (which seems to be where the text writing functionality is stored). I don't have to have the Write library be the particular one I've specified, but I do need some way to write text onto a cylinder.

Let me know if you need any more clarification!

Okay, I'm looking to create a customizable Christmas tree ornament, kind of a spiral sphere design. I'd like to be able to control a few things, and I'm hoping you can generate the OpenSCAD code for me.

Here's what I envision:

1.  **Number of Ribbons:** I want to be able to specify how many "ribbons" wrap around the sphere. It should be a number between 4 and 20.

2.  **Spiral Type:** I'd like to choose between having one continuous spiral (a single helix) or two spirals that go in opposite directions (double helix).

3.  **Overall Diameter:** I need to be able to set the diameter of the sphere. The minimum should be about 20mm and the maximum should be 100mm.

4.  **Wall Thickness:** I need to control the thickness of the ribbons, with some options like very thin (0.25mm), thin (0.5mm), standard (0.75mm), and thick (1mm).

5.  **Ribbon Width:** Finally, I'd like to be able to set the width of each ribbon, with a range of 2mm to 10mm.

So, to recap, it's a spherical ornament with spiraling ribbons. It should also have a small flat base so it can stand up and a little hanger at the top so I can put it on the tree. All these parameters should be customizable. I'm not sure if you need any libraries for this, but if you do please specify them.

Could you please generate a single .scad file for me with these customizable parameters? Thank you!

Okay, I'm looking to get a parametric OpenSCAD design for a shadow band, something that can be 3D printed. I've got a basic idea already, but I need something that's fully customizable.

The core of the design is a cylinder, which will be the main band, but instead of being a complete cylinder, it will have a section removed. It's going to look somewhat like a C shape when viewed from the end. Think of it as a thick metal strip bent into a partial ring. I'd like to be able to adjust the height, radius, and thickness of this main band.

I also want to have a central extension – a cylindrical post coming out from the center of the C. This should be adjustable in terms of its width, and have a cylindrical hole going through the center of it.

Here are the specific parameters I'd like to control in the design:

*   `band_height`: The height of the cylindrical band.
*   `band_radius`: The radius of the cylindrical band.
*   `band_thickness`: The thickness of the cylindrical band.
*   `center_extension_width`: The width of the central cylindrical post.
*   `center_extension_hole_diameter`: The diameter of the hole through the center of the post.
*  `segment_angle`: The angular range of the main band - how much of the full circle it covers. This should also control the cut-out section. It should be set so that it is centered on the top of the band. So 90 degrees would be 45 degrees on either side of the top.

I'd like all these parameters to be accessible in the OpenSCAD file so that I can easily modify them. Please use a high level of mesh density for all cylinders so that the final render is as smooth as possible.

For the file or files that you generate, please be sure to include comments that explain what each section does, and comments for each parameter.

Could you provide the OpenSCAD code for this? I don't need any extra libraries, just core OpenSCAD features.

Okay, I'd like to request a new OpenSCAD design, something like a cluster of crystals growing from a base, kind of like a geode or a fancy mineral formation. I've seen some cool designs like the "Giant Crystal" on Thingiverse by Tothe, and something similar would be great.

Specifically, I'd need the design to be parametric, so I can adjust different aspects of it. Here's what I'm thinking:

*   **Number of Crystals:** I want to be able to set how many individual crystals there are in the cluster.
*   **Crystal Width:** I'd like to specify a minimum and maximum width for the crystals. This will allow some variety in their size.
*   **Crystal Height:** I'd need a parameter to control the overall height of the crystals.
*   **Number of Sides:** Each crystal should have a controllable number of sides, like a polygon. So, 6 for hexagonal, 5 for pentagonal, etc.
*   **Crystal Dropoff:** The crystals shouldn't all extend out to the same distance from the base - outer crystals should be shorter. I'd like a parameter that can control this effect. Lower values should create shorter outer crystals.
*   **Overhang Angle:** I want to be able to specify an angle so the outermost crystals flare out from the base. It would be awesome if there was a way to control this angle.
*   **Crystal Density:** This should control the overall "density" of the crystals.
*   **Base Width:** I'll need a way to set the width of the base that the crystals grow from.
*   **Randomization Seed:** Finally, I want a way to control the randomness, so I can reproduce the same crystal arrangement by specifying a seed number.

The overall look I'm going for is a cluster of varying sized, angled crystals growing out of a base. Each crystal should be formed by a cylinder with a tapering top and the whole structure should be customizable with the above parameters.

I think that's everything! I'm not too worried about the exact algorithm, as long as it works to create something that looks like a cluster of crystals. Thanks in advance for your help. I'm hoping that you can write the OpenSCAD code for me. I'm not using any libraries.

I'm looking to create a parametric battery holder for button cell batteries using OpenSCAD. I've seen a design that works, but I'd like to build one that is more flexible and easier to customize.

Here's what I need:

*   **Parametric Design:** The design should be easily adjustable for different battery diameters and heights. I want to be able to change parameters for battery diameter, battery height, tolerance around the battery, and wall thickness.
*   **Basic Shape:** The holder should be a cylindrical cup with a cutout on one side to allow the battery to be inserted. The cutout should also allow for wires to be threaded through to make electrical contact with the battery.
*   **Tolerance:** I'd like to specify a tolerance value that defines the space between the battery and the holder walls. This is useful to get the snugness of the fit correct.
*   **Wall Thickness:** The thickness of the holder's walls should also be adjustable to control strength.
*   **Wire Holes:** The design should include small holes on each side of the cutout, suitable for wires to make contact with the battery. These should be placed horizontally through the side walls of the cup. I'd like to specify a diameter for the wire holes.
*   **Single Cell:** The holder is only designed for a single button cell.
*   **No Base:** I do not need a base.
*   **OpenSCAD:** The design should be created using OpenSCAD.

Here are some example parameters for the design, but I need to be able to change them all:

*   **Battery Diameter:** e.g., 12mm, 20mm
*   **Battery Height:** e.g., 2.5mm, 3.2mm
*   **Tolerance:** e.g., 0.2mm, 0.5mm
*   **Wall Thickness:** e.g., 1mm, 2mm
*   **Wire hole diameter:** e.g., 0.8mm

Could you generate the OpenSCAD file(s) to accomplish this? I don't need any external libraries for this design.

I'd like to design a customizable Christmas ornament, essentially a tree-like structure with several horizontal bars connected by a central vertical support. The bars should have holes in them for hanging decorative items, and I'd like to be able to adjust the positions and spacing of these holes.

Specifically:

*   There should be a central vertical support, a rectangular prism that is centered. I'd like to control its height and width as parameters.
*   There should be a series of horizontal bars extending from the central support. These bars should also be rectangular prisms with adjustable lengths, widths, and positions along the vertical axis.
*   Each horizontal bar should have a number of holes placed symmetrically around its center. I want to control the distance of each hole from the center of the bar and control the hole diameter/radius.
*   The bars should also have small angled supports connecting them to the central support, two on each bar. The angle and position of these supports needs to be parametric, as well as their length, width and height.
*   I would also like a conical hole at the top of the center support for a hanging string.  I need to control the size and position of the cone and hole.
*   All of these dimensions - heights, widths, lengths, hole distances, cone parameters - should be parameters in the code, so I can easily tweak them. I'd prefer a single scad file to keep things simple.

Please generate an OpenSCAD file for this design. I'm not using any external libraries, so you don't need to worry about including any. Thanks!

I'd like to design a pencil holder that arranges pencils at an angle so they lean on each other. I have a basic idea of the shape, but I need some help making it parametric so I can adjust the number of pencils, their size, and the lean angle.

Here's what I'm envisioning:

*   **Pencil Arrangement:** The holder should position the pencils in a circle, leaning inwards. The pencils should all meet at a point if they were long enough.
*   **Parametric Controls:**
    *   `NUM_PENCILS`: The number of pencils the holder will hold.
    *   `PENCIL_DIAMETER`: The diameter of each pencil.
    *   `PENCIL_LENGTH`: The length of each pencil (this is mostly for calculation purposes, I think)
    *   `LEAN_ANGLE`: The angle at which the pencils lean inward.
    *   `BASE_HEIGHT`: The height of the base of the holder.
    *   `WALL_WIDTH`: The thickness of the base walls.
    *   `PENCIL_SHIFT`: A horizontal offset for the intersection point of the pencils.
*   **Shape:** The base should be a cylindrical shape, wider at the bottom and narrower at the top, like a truncated cone (frustum) for better stability, and with a hole cut out in the center. The pencils will be held by individual holes cut at an angle from the outside to the center.
*   **OpenSCAD Library Requirements**: I'd like to be able to customize the shape of the design further. I think I might be interested in using BOSL2 library, it seems very powerful.
*   **Output:** I'd like to get the final design as one or more `.scad` file(s) that I can then tweak further if needed.

Can you generate that for me? Thanks.

Okay, I'm looking to design a tiltable and rotatable mount for those circular G4-type SMD LED lamps, the kind you often find on eBay.  I've seen designs out there, but I'd like to have a parametric one I can adjust for different sized LED boards and to make it just how I want.

Essentially, I need two main parts: a holder for the LED board itself, and a base that the holder connects to. The holder should snap into the base using a conical hinge design that allows for tilting. This hinge needs to hold by friction, but should also include screw holes so I can tighten it more firmly if needed. The whole assembly should be able to rotate around a central mounting screw hole on the base, and also needs a small hole on one edge for running wires through. The LED holder should have cut-outs to allow air to circulate around the LED board to help with cooling. I'd like the LED carrier to snap into the led holder, and would like to have the space behind the led available so wires can fit there.

I'm familiar with OpenSCAD and would want the design to be entirely parametric, so I can change things like:

*   **ledD**: The diameter of the LED carrier board itself. This needs to be adjustable, as there are different sizes (like 23mm, 24.5mm and 30mm, and 22mm like I've seen).
*   **wall**: The thickness of the walls in the printed parts
*  **ledM**: Margin around the LED board where the holder starts
*   **ledH**: The height of the LED carrier board
*   **ledP**: The vertical position of the snap-in "click" feature (as a fraction of ledH)
*   **ledC**: The depth of the snap-in click
*  **ledG**:  Gap width between the air cooling cutouts
* **ledB**: Space needed behind the led for wiring.
*   **hingeW**: The width of the hinge
*   **hingeD**: The depth of the hinge
*   **hingeH**: The height of the hinge
*   **hingeR**: The radius of the hinge
*   **eps**: The separation between the outer and inner parts of the hinge (if any)
*   **granu**: The angular granularity of the hinge (for smoothness)

I'd like to have two separate modules, `ledholder` and `ledbase`, for each of the components. And maybe a combined module called `compose` for visualizing how it all fits together at a specified tilt angle.

Could you generate the OpenSCAD files for these, please? I think all of this can be done with the standard OpenSCAD libraries, so no need to include other libraries for this design.

Hi there, I'm looking to create a customizable rack for holding cuvettes or small vials, and I'd like to use OpenSCAD to generate the design.

Here's what I'm envisioning:

The rack should consist of a grid of cylindrical or square holes. I'd like the option to choose between round and square holes. Also, the rack should be based on a grid layout, with a set number of rows and columns.

I need to be able to control several parameters:

*   **`hole_shape`**: A variable to switch between round and square holes (e.g., 1 for round, 0 for square).
*   **`hole_size`**: The diameter of round holes or the length of a side of square holes.
*   **`hole_depth`**: The depth of the holes in the rack.
*   **`rows`**: The number of rows of holes in the rack.
*   **`columns`**: The number of columns of holes in the rack.
*   **`spacing`**: The distance between holes (edge to edge).
*  **`bottom_thick`**: The thickness of the bottom layer of the rack.
*   **`hole_punch`**:  A boolean variable to specify whether or not a central hole should be punched through the bottom of each chamber.

I'm hoping the design will automatically create the main body of the rack and then subtract out the holes in the specified grid layout. I think it'll be easier to 3D print if the central drain hole is added.

I'd be very grateful if you could generate the necessary OpenSCAD code for me. I don't have any experience using libraries like MCAD, BOSL, BOSL2, dotSCAD, NopSCADlib, or BOLTS so please do not include them in the design.

I'm looking to generate a customizable multi-well plate design, specifically one that can be easily adjusted to different sizes, mimicking the layout of a 96-well plate but without a skirt. I want to be able to define the number of rows and columns, the wall thickness, the well diameter, well depth, the spacing between well centers, and the thickness of the well bottoms.

Could you generate the necessary OpenSCAD files for this? I'd like it to be fully parametric, so I can easily change all of those measurements and the number of wells. Basically, I want to generate a well plate with a rectangular grid of cylindrical wells. The wells should have a flat bottom. The wells are connected by rectangular prisms.

I don't need any special libraries for this design, I just want to use base OpenSCAD functionality.

[User]
I'd like a parametric OpenSCAD script that can generate nuts, bolts, washers, and threaded rods, similar to the "Nut Job" script on Thingiverse. I want to be able to control all the dimensions through parameters, of course.

Specifically, the script needs to handle:

*   **Different component types:** I need to be able to choose whether I'm generating a nut, a bolt, a rod, or a washer.
*   **Bolt Head Types:** For bolts, I want to choose between a hex head, a socket cap head, a button socket cap head, or a countersunk socket cap head.
*   **Drive Types:** For socket cap, button, and countersunk heads, I need to select between socket, Phillips, and slot drives.  The slot drive should allow setting a slot width and depth.
*   **Thread Options:**  The script needs to allow me to set the outer diameter, pitch, and step shape angle for the threads, as well as the thread length. It should also include a countersink option.
*   **Non-threaded Section:** The bolts and rods should optionally include a non-threaded section, with the ability to specify the length and diameter of this section. The diameter should have an option to match the inner diameter, the outer diameter, or a user specified value.
*   **Nut Options:**  Nuts need to be either standard or wing nuts. I'll need to set the outer diameter and height for both, and the wing ratio for the wing nuts. The thread parameters for nuts should be independently controllable, allowing for a slightly larger inner diameter to create a proper fit with a bolt.
*   **Washer Options:** I should be able to define the inner diameter, outer diameter, and thickness of washers.
*   **Extended Options:** I would like to have a way to specify the number of facets on hex heads, nuts, and socket drive holes, and the depth of the socket drive hole. I'd like a resolution option that controls the level of detail for curves; this should apply to both nuts and bolts.
*   **Texture:** For socket head bolts there should be an option to include or exclude texture on the sides.

The generated parts should work well together without modification.  I'd also like the threads to be generated using the same algorithm as in the original script - I believe it's based on a library called "polyScrewThread.scad", so please incorporate that in.

I'm not asking you to create a customizer interface; I can use the built in OpenSCAD customizer for that.  Just a good, parametric script or collection of scripts that would provide these capabilities would be great.

Hi, I'm looking to create a personalized Christmas ornament and I'd like some help generating the OpenSCAD code for it. I've previously created one, but I'm starting over from scratch, and I'd like to make it fully parametric.

The ornament should be a sphere with a ring around it.  The sphere should be hollow, so a smaller sphere inside is removed, along with rectangular cutouts to create a window-like effect.  Inside the hollow sphere, I'd like to have a few different elements: a number of snowmen, presents, and a tree.  I'd like the number of snowmen to be adjustable, up to 5.  Each snowman should also have a gender that can be toggled between "man" and "woman."  I'd like to add some simple presents and a tree to complete the scene inside the sphere.

The ornament should also include text on the outside and inside of the sphere. On the outside, I want the text "Merry Christmas" repeated twice, placed on opposite sides. This should be engraved into the sphere surface and not printed separately. The text inside should be a customizable name or phrase and the current year. These should also be engraved on the interior surface of the sphere. I'd need parameters to set the name text and its size, as well as the year.

I'd also like to have an option for generated support, but instead of generating actual support material, I'd like the code to create small tabs and cones as support structures that I can easily break off after printing. I'd like to be able to toggle this on and off. This approach was used in a previous version of this design.

I'd like to be able to adjust different colors using parameters, for instance, main body, globe text (outside sphere text), snowmen hats and buttons, main scene color, presents ribbon, tree, and scene text (inside sphere text). These parameters should essentially toggle objects on and off, effectively turning them on if color is "1" and off if set to "0".

For text, I'd like to use the `Write.scad` library for writing the text. Can you generate the SCAD code to do all this? I'd also like to use the `knewave.dxf` font, specifically. Let me know if you need any more details, thanks!

[Assistant]
ornament_v2.3.scad:
```
use <write/Write.scad> ;
/* [Text] */

// Or any message
nameText = "MakerBot";

// May need to adjust this to make nameText fit nicely
nameTextScale = 7;

/* [Snowmen] */

// Adjust for family size
numberOfSnowmen = 5; // [0:5]

// Largest Snowman
snowmanOneGender = 1; // [1:Man,0:Woman]

snowmanTwoGender = 0; // [1:Man,0:Woman]

snowmanThreeGender = 0; // [1:Man,0:Woman]

snowmanFourGender = 1; // [1:Man,0:Woman]

// Smallest Snowman
snowmanFiveGender = 0; // [1:Man,0:Woman]

/* [PrintSettings] */

// You may need if you arn't printing with generated support (That's how I printed)
enableSupport = "Yes"; // [Yes,No]

/* [Year] */
yearText = 2015;

/* [Hidden] */

// Going to upload a dualstrusion version sometime.
//enableDualPrint = 0; [0:No,1:Yes];

// A few different things to toggle on and off when playing with dual extrusion
// Set the colors to 1 that you want on, and to 0 to subtract the items
// Note, if you place scene objects overlapping, the colors may not subtract correctly causing an overlap
// (eg. if you embedded one present into another and turn off primary scene color or ribbon color)

// I think main body,ribbon, and year text in a bright color, with the rest being in an off white looks great!
color1 = 1; // Main body
color2 = 1; // Globe text (Text on out side of globe)
color3 = 1; // Snowmen hats and buttons
color4 = 1; // primary scene color
color5 = 1; // Presents ribbon
color6 = 1; // Tree
color7 = 1; // Scene text  (Text that's part of teh scene)

I want to create a custom cryptex-style ring that can be used with the flash drive cryptex project on Thingiverse. I need an OpenSCAD script that will generate this ring with customizable text on the outside or inside.

Here's a breakdown of what I need:

**Ring Structure:**

*   The ring should be a cylindrical shape with a channel cut into the inner circumference. This channel needs a gap so the ring can unlock (as shown on the thingiverse page).
*   I need to be able to specify the outer diameter, inner diameter, diameter of the channel, width of the channel, and the height of the ring. I think I understand the structure in the provided code so here are those variables as I would expect to use them: `diameter_in`, `diameter_out`, `diameter_channel`, `channel_width`, and `ring_height`.
*   The ring should have a resolution of 50 faces per unit, controllable with the standard `$fn` variable.

**Text Customization:**

*   I want to put text around the circumference of the ring. This text will be composed of up to 10 symbols that I want to be able to individually customize. I should be able to select these symbols from letters, numbers, and special characters.
*   I need to be able to choose where the text is positioned - either on the outer surface of the ring, or imprinted into the inner surface of the channel.
*   I need to be able to specify the font used for the text. I would like to start with 'Letters.dxf', but be able to substitute 'BlackRose.dxf', or 'orbitron.dxf' later. This means I need to have some way to include my own fonts, I think the given code uses some kind of `write` module?
*   The text should have configurable height and depth. I need `font_height` and `font_depth` to work.
*   The text should be positioned evenly around the ring (i.e., 10 symbols, evenly spaced).
*   I need to be able to select which of the 10 symbol positions is the "opening position" (the position where the gap is located). This should be numbered 1 through 10.

**Modules Needed**

*   A main module to generate the ring structure including the cylindrical shape, the channel, and the gap.
*   A module to create the text around the ring, and to either imprint or extrude it based on the `font_position`.

I'm hoping you can generate a parametric OpenSCAD script (or multiple if needed) that will include all the functionality described, including the necessary `write` module and the dxf font files. I don't need any other libraries for this.

[Assistant]
RingCustomizerFonts.scad:
```
//inclusion of the write.scad in the Makerbot Customizer
//The directory "write" has to include Write.scad and the dxf-files,
//also the write-directory has to be in the same directory as this file

use <write/Write.scad> //customizer's location
//resolution faces
$fn = 1*50;

//Symbols

// Number, letter or special character
symbol_1="1";
symbol_2="2";
symbol_3="3";
symbol_4="4";
symbol_5="5";
symbol_6="6";
symbol_7="7";
symbol_8="8";
symbol_9="9";
symbol_10="0";

Hey, I'm looking to generate a 3D-printable sign that shows the distance from a given location to the North Pole. I want to be able to customize it with my latitude, have a choice of showing the distance in either miles or kilometers, and pick whether the arrow points left or right.

I already have a basic idea for the sign shape and text layout from a project I found online. I'd like to use that sign shape as a starting point, so I'll describe it. It has a sort of irregular, almost shield-like outline with a few curves and angled edges. There's a thicker base layer that's red, and a slightly thinner white layer on top of it that acts as a border. The text needs to be extruded on top of the white border as well. The text consists of two lines: "North Pole" on top, and then the distance on the bottom. The distance can be calculated based on the latitude input.

For the parameters, I need to set the latitude in degrees from the equator (the first number in a GPS coordinate). I need a parameter for `arrow_direction`, which can be either "left" or "right". And a parameter for `distance_units`, which should let me choose between "Miles" or "Kilometers".

Could you generate the necessary OpenSCAD files for this? I know the original design used the `write.scad` library from Thingiverse, but please don't use that library. I don't want any external library dependencies. I think you should be able to create the text extrusion functionality yourself, or use the built-in text capabilities within OpenSCAD. Also, please provide a hook so that I can hang it from something.
