Hi! I'm looking to design a customizable container for liquids and small objects, and I'd like your help creating the OpenSCAD files. I have a basic idea for the geometry, but I need it to be parametric and adjustable.

Essentially, I want a container that's a polygon-based cylinder with a specified target volume. The user should be able to set the volume in milliliters, fluid ounces, or cups, and the design should automatically scale to match. I'd also like the user to control the number of sides for the polygon, the wall thickness, and whether the container is "tall" or "wide" - where "tall" is approximately 1.6x the radius, and wide is approximately the radius.

Here's a breakdown of the parameters I envision the user controlling:

*   **`volume`**: The target volume of the container as a number.
*   **`conversion`**: A dropdown selection, or similar, to select the units for the volume: `1` for milliliters (mL), `29.5735` for fluid ounces (fl oz), and `236.5882` for cups (c).
*   **`sides`**: The number of sides of the polygon base for the cylinder.
*   **`thickness`**: The wall and bottom thickness of the container.
*   **`shape`**: A selection, possibly a dropdown, for 'Tall' or 'Wide'. This will adjust the height to radius ratio to be approximately 1.6:1 (Tall) or approximately 1:1 (Wide).

For the "shape" option, a value of `1` should indicate "Tall", and `0` for "Wide". The conversion of units should be handled internally and only the selected units used as input.

I'd like the output to be a single STL file for the whole container. The container should have a hollow interior, so it needs to be the difference of two cylinders. The inner cylinder should be just slightly taller than necessary, and then it should be subtracted from the outer cylinder.

Could you generate the necessary OpenSCAD file for me, and provide any needed explanation on how to use it? I'm expecting it will require a fair bit of math to translate the parameters into the appropriate cylinder dimensions.

I'd like to create a cable clip for aluminum extrusions, specifically designed to snap onto a profile and hold a cable in place. I have some specific parameters I need to be adjustable.

The clip should have a main body with a rectangular cross-section that wraps around the extrusion. The inside dimensions of this body will vary based on the extrusion profile I'm using. I will be inputting the width and depth (outside dimensions) of the extrusion, as well as the wall thickness of the clip itself (all in mm). It should have a snap-on design, with two hook-like features on opposite sides of the body. These "hooks" will extend inwards to grip the extrusion profile. The distance between the hooks (the opening that the extrusion will be inserted into) will also need to be a parameter. Finally, I need a hole for a zip tie, going through the center of the clip, that will allow the cable to be held in place. This hole needs to have a parameterized diameter. I plan to use the MCAD library for rounded boxes and teardrop shapes if that makes things easier. Could you please generate a parametric OpenSCAD file for this?

I'd like to design a customizable snowman for 3D printing. It should be made up of separate parts that can be printed individually without supports.

Here's what I'm thinking:

The snowman should consist of a hat, a head with eyes, a mouth, a nose, the main body (three connected spheres), arms, and a base.

I need to be able to customize a few things:

1.  **Individual Part Selection:** I want the ability to render and preview any specific part on its own – so the hat, the head, the nose, the body, the entire assembled snowman in a "model view," or just the parts in a "printable view".
2.  **Overall Size:** I need to adjust the total height of the assembled snowman, let's say from 50mm to 200mm.
3.  **Render Quality:** I would like a simple way to control the render quality to speed up previews.
4. **Colors:** I'd like the individual parts to have configurable colors by default: black for the hat, eyes, and mouth, snow color for the head and body spheres, orange-red for the nose, and deepskyblue for the bottom base.

The "model view" should show the snowman assembled as it would look in the final product, including the eyes, mouth, arms, and nose correctly positioned. The "printable view" needs to arrange the parts in a way that they can be printed without any supports. The eyes, mouth, and nose should be rotated for easy printing, and the hat needs to be separated from the head. The arms should also be separated from the body. The nose should have a flat connection point.

I am using the `write/Write.scad` library that was included with the original code submission, so make sure that is used in the code that is output.

//1. Made it all into a single oprnscad program, and make it costomizable.
//2. You can reveiw every individual parts and model view or printable view, every single parts are printable.
//3. You can choose the height, collors, render quality, and every individual parts you want.
//4. If you want to print that snow man, you need to print the printable view program, because that is printable and you do not need any supports.

I want to design a parametric gauntlet, like the kind used with e-NABLE prosthetic hands, but made from parts that are 3D-printable flat on the print bed and then hinged together. I've got some ideas, and I'd like to see if you can make an OpenSCAD design for it.

The basic idea is to have a few core parts: "left bar", "middle", and "right bar" pieces. Then, you can add any number of "left join" and "right join" pieces in between to customize the length for different arms. These parts will all hinge together.

Here are the specific parameters I'm thinking of, which I'd like to be adjustable in the OpenSCAD design:

*   **`part`**:  This is going to be an integer selector, where -1 is for showing the assembled gauntlet preview, 0 shows all parts laid flat for printing, 1 is the "right bar", 2 is the "right join", 3 is the "middle" part, 4 is the "left join", 5 is the "left bar", and 6 is the tensioner pin. This lets me look at specific pieces easily.
*   **`len`**:  The length of each of the "bar" and "join" segments.
*  **`rib`**: The thickness of the frame of the 'bar' or 'join' parts.
*   **`holeD`**: The diameter of the holes that will act as hinges. This should be able to be set to 2mm for 1.75mm filament and 3.5mm for 3mm filament.
*   **`boltD`**: The diameter of the wrist pin hole.
*   **`velcroWide`**: The width of the Velcro slots on the bars. I'm thinking either 37mm for 1.5-inch Velcro or 50mm for 2-inch Velcro.
*   **`tensionerPins`**: How many tensioner pins I need on the 'middle' section.
*   **`middleWide`**: The width of the 'middle' section, which includes the tensioner.
*   **`pinSize`**: The height of the tensioner pins on the 'middle' section.
*   **`tensionerHoleD`**: The diameter of the screw holes in the tensioner pins.
*   **`thick`**: The thickness of all of the printed parts.
*   **`bump`**: The height of the bumps that connect the ribs of each piece.
*   **`bumpLen`**: The length of those bumps.
*   **`numBumps`**: The number of 'bumps' along each piece.
*   **`gap`**: The clearance between parts to allow for easy movement.
*   **`velcroThick`**: The thickness of the material around the Velcro slots
*  **`tensionerLen`**:  The length of the tensioner section on the middle piece.
*  **`tensionerWall`**: The thickness of the wall of the tensioner.
*   **`tensionerBack`**:  The thickness of the back wall of the tensioner, which I need to be a bit thicker for strength.

I also have some 'calculated' parameters:
*   **`tensionerWide`**: width of the tensioner, calculated based on the pin size and number
*   **`tensionerTall`**: the height of the tensioner based on pin size and wall thickness

I need some modules, too:

*   **`bar(hole, top, bottom)`**: This module should create a bar/join part.  The `hole` parameter toggles the wrist pin holes and velcro slots. The `top` and `bottom` parameters control whether the bumps that connect it to the next part are on the top or bottom face.
*   **`middle()`**:  This module will create the central part with the tensioner pins and corresponding cutouts for them.
*   **`pinHole()`**: This module creates the hinge holes for filament pins and includes some material removed to allow for hinging.
*   **`bumps()`**: This generates the bumps on the top of the bar or join piece that slot into the next piece.
*   **`bumpsDown()`**: This module creates the matching slots for the bumps, including some cutouts.
*   **`tensioner()`**: This module creates the tensioner section on the middle part.
*   **`pin()`**: This creates an individual tensioner pin.
*   **`plated()`**: This module shows all the parts laid flat as they would be printed.
*   **`assembled()`**: This module shows a preview of the gauntlet assembled.

I think that's everything. Let me know if you have any questions.

I need a parametric OpenSCAD design for a rod connector, something like you'd use on a 3D printer like a Rostock or Kossel. I want to be able to connect a rod to this connector, and I need to be able to choose whether the outer shape of the connector is round or square.

Here are the parameters I need to control:

*   `Rod_diameter_outside`: The outside diameter of the rod that will fit into the connector.
*   `Jaws_diameter_outside`: The outside diameter of the "jaws" of the connector, where it might connect to something else (this will also be the diameter of the inner hole on one side of the connector) .
*   `height`: The total height of the connector.
*   `Wall_thickness`: The thickness of the walls of the connector.

The connector should have a cylindrical bore on one side sized for `Rod_diameter_outside` and a larger bore on the other side sized for `Jaws_diameter_outside`. The material of the connector should be `Wall_thickness` thick, surrounding those bores, forming the main shape. I need to be able to select if the external shape of the connector is round or square. The square option should have rounded corners. I am not going to be using any external libraries.

I also would like a good default value for `$fn`, maybe something like 50, and I want to be able to control it if needed.

Hey, I'm working on a customizable snowman project, and I'm stuck on adding text. I've got the basic snowman parts working, like the spheres for the body, eyes, mouth, nose, arms, a hat, and even a nail detail. It's all laid out in an OpenSCAD file where I can render individual parts, view an exploded version, or see the assembled snowman. I'm using a `write/Write.scad` library to get text functionality (I realize now this isn't ideal and you'll probably want a different approach).

I'm thinking I'd like the ability to add a custom text message to the snowman, maybe wrapping around the middle sphere, or even on a separate sign object that I can position near the snowman. It should be customizable— I want to change the text, the font, the size of the text, and even how far the text extrudes from the surface or how tall the letters are if it's a separate sign object. I'm not sure where the text would look best, so maybe allow me to pick placement and rotation of the text too. Could you generate the necessary OpenSCAD files, including any needed libraries, for me to do this? I'd like to use a standard font if that's possible, but also would like the option to choose between a few different font options if possible.

I'd like to create a 3D model of a snowman, and I'd like it to be parametric so I can adjust its size and features. I've got a pretty specific idea in mind, but I need help creating the OpenSCAD code for it.

Here's what I'm looking for:

The snowman's body should be made of three stacked spheres of decreasing size, with the largest at the bottom and the smallest at the top. The bottom sphere should have a flat bottom, as if it's been cut off by a horizontal plane.

I need to be able to scale the entire snowman using a `scale_factor` variable, with a reasonable range of say, 0.8 to 2. The fineness of the curves should be adjustable using `$fn`. I'd like to be able to set the value of `$fn` to LOW, MED, or HIGH with corresponding values of 25, 40, and 100.

The snowman's features should be separate pieces that can be glued into place after printing. This includes:

*   A smile made of several small cylindrical pieces, arranged in a curve.
*   A cone-shaped nose.
*   Two small cube-shaped eyes.
*   Two cylindrical arms.
*   A hat made of two stacked cubes.

I'd also like the option of adding an ornament hook to the top, which should be a sphere attached to a cylinder. This should be controlled by a boolean variable `ornament_hook` set to 0 for no hook and 1 for the hook.

Finally, each of the separate pieces (smile, nose, eyes, arms and hat) need to be created as *separate* objects in the scad file, not as subtractions from the body.

Could you help me generate an OpenSCAD file for this? I'm not using any specific libraries for this.

I'd like to design a parametric snowman toy for 3D printing, and I think I'll need some help from you. I've got a few ideas for features and parameters, and I want to make sure it's flexible enough for different printing needs.

First, the snowman should have the classic three-sphere body. I want to be able to adjust the radius of each sphere and the vertical distance between them. I'd like to be able to control the overall quality of the render, too; a draft setting for quick previews and a production setting for the final print.

He also needs arms, probably just simple cylinders coming out the sides. Let's make those adjustable in length and radius, with an angle parameter to change their direction.

For facial features, he'll need a carrot nose (a cone, I guess), with adjustable length and base radius. He should have simple eyes and a mouth made of little cubes. The positions of those should also be parameterized.

To make him a bit more fun, I want him riding a snowboard, which should be a central flat piece with rounded side edges and a difference() at the tips. And I also need a parameter to select if there's a hook on the back of his head for a string to turn him into a hanging ornament.

I guess that's most of it. It would also be good to have a base so he doesn't tip over. Can you generate the OpenSCAD code for this, please? I'm new to OpenSCAD, so I'm not sure what libraries I might need, but hopefully, you can handle that for me.

Hey, I'd like to design a customizable skiing snowman using OpenSCAD. I have a basic idea of the components and parameters I'd like to control, and I think this could be a fun project.

Here's what I'm envisioning:

The snowman should be made of three spheres, stacked on top of each other, with the largest at the bottom. I need to be able to control the overall scale of the snowman.

The snowman needs arms made of cylinders, sticking out at angles. I think 45 degrees up and down should look good, and they can just be simple sticks. It will need a carrot nose, which I'd like to make as a truncated cone. It should have eyes made of small cubes. Also, I'd like the mouth to be a series of small cubes creating a curve.

It needs a top hat on its head, made of two cylinders.

Finally, it should have skis. I'd like to use two elongated rectangular prisms for the skis, with cylinders on top, where the feet would theoretically go.

I'm also going to want some controls for the quality of the render, maybe just a simple `$fn` variable I can adjust.

I'd like to be able to render the whole snowman with the hat and skis, the snowman without the hat and skis, and a version that is split into parts for printing.

Can you generate an OpenSCAD file for me that I can customize?

Hey, I'm looking to design a parametric snowman in OpenSCAD, and I'd like to be able to customize a few things. I've seen a few existing designs online, but I want something that is easy to print in multiple parts and assemble, almost like a model kit.

Specifically, I'd like the snowman to be made up of three stacked spheres of increasing size from top to bottom for the body, with the bottom sphere being the largest and the head being the smallest.  I’d like the spheres to be slightly offset from each other to avoid full overlap, which should help with printing without supports (although I am not concerned with supports, especially on the face part.) I want to control the overall size of the snowman, meaning that when I change the overall height of the snowman the sphere radii are also re-calculated. The project size I am envisioning could be around 70-125mm tall when assembled.

I also need to add a few common snowman features - a couple of stick arms, a simple top hat, a scarf, and gloves. The arms should be cylinders, and I want to control their length and angle, and ideally, they'd be a different color from the body. The hat should be a simple cylinder with a slightly larger radius for the brim, also a different color. The scarf should also be a short cylinder wrapped around the neck, again, with a different color. Finally, the gloves can just be smaller cylinders at the ends of the arms, again in a different color.

Finally, I'd like a separate face part, so the eyes, nose and mouth can be printed separately and attached to the head of the snowman. The nose should be a cone shape. I would like the face to be offset a little to the front, to give it some depth. The eyes and mouth should be composed of several small cubes.

For printing, I want to split the body into two halves which can then be glued together. I'd also like to be able to render just the front face piece, or the back body piece, or all pieces, using a customizer parameter.

It would be great if I could control the overall project size with a parameter, and if the draft/production rendering quality could be a variable as well.

I'm thinking of using the `color()` module, so please make sure any color customization is included as parameters.

Could you generate the OpenSCAD code for this, including comments where appropriate? No libraries are needed beyond the built-in OpenSCAD modules.

I'd like to design a parametric snowman in OpenSCAD. I want to be able to customize a few things, including the overall size, text on the body, and rendering quality.

Specifically, I'd like the snowman to be made of three spheres stacked on top of each other, with the smallest sphere on top as the head and the largest at the bottom for the base. The head should have a small cone for a nose, two cube eyes, and a curved mouth made of several cubes. It also needs a small top hat. The torso should have three button spheres. The arms should be short cylinders sticking out to the sides, angled slightly upwards.

I also need to be able to add text to the torso. I'd like two lines of text wrapped around the middle sphere, one above the equator and one below. I need to be able to control the font and the height of the text, and shift them slightly up or down. The font choice should be from the `write` library.

Finally, I want to control the overall size of the snowman with a `scale_factor`, and the quality of the rendering with a `Render_Quality` variable, to speed up previewing. And I would like all of the measurements to be in millimeters.

Can you generate the OpenSCAD code for this? I'm not sure if it matters, but I don't have any pre-existing files.

Hey, I'm looking to design a parametric snowman in OpenSCAD, but with a twist. I want to be able to switch between a happy and an angry version, and also have it be printable in a couple of different ways.

Here's what I'm thinking:

*   **Overall Structure:** The snowman should be made of three spheres stacked vertically - a larger base, a medium mid-section, and a smaller head. I want parameters to control the size of each sphere as well as the overall height.

*   **Arms:** The arms should be stick-like and attached to the middle sphere. For the "happy" version, the arms should be simple cylinders angled slightly upwards.  For the "angry" version, the arms should have an extra angled segment and a small ball at the end. Basically, like a stick that makes a zig-zag.

*   **Face:** The nose should be a cone, pointing outwards. For the "happy" version, the eyes should be small rectangular blocks rotated slightly outwards, to give a cheerful look. For the "angry" version, the eyes should be the same blocks but rotated inwards, giving it a scowling look.  I'd also like to vary the length of the nose -- it should be longer for the angry version.

*   **Mouth:**  The mouth is where the personalities really come out. For the "happy" version, I want a semicircle of small cubes. For the "angry" version, I want the mouth to be a row of recessed spheres, like teeth. They should appear embedded in the front of the head.

*   **Accessory:** I want to give the snowman a pipe that sticks out of his head at an angle, like a jaunty hat. However, since this is for 3D printing, I need to add a couple of thin supports that will break off after printing so that there isn't a 90 degree overhang.  It should also have a little cap on the end.  This part should print separately and then slot into the snowman, so there should be an indentation in the head as well to receive it.

*   **Printing:** I need two main printing modes: one where everything is assembled and another where the snowman is "split" into two halves behind the arms, with the pipe also as a separate piece. The pipe should still be able to be inserted into a socket in the assembled snowman.

*   **Parameters:** Here's a summary of the parameters I want to control:
    *   `Personality`: An integer to switch between happy (0) and angry (1).
    *   `Render_Detail`: An integer to control `$fn` for rendering detail.
    *   `View`: An integer to switch between assembled (0) and split/printable (1) mode.
    *   `snowmanHeight`: The total height of the snowman.
    *   `baseSph`: Radius of the base sphere.
    *   `midSph`: Radius of the middle sphere.
    *   `headSph`: Radius of the head sphere.

I think that's everything! I'm not using any specific libraries like MCAD or BOSL, so all of this would need to be coded from scratch.  Let me know if you have any questions.

I'd like to design a parametric snowman for 3D printing, and I'm thinking it should have a few different parts that can be rendered separately or together. I'm hoping you can generate the OpenSCAD files for me. I'd like to be able to control the overall size of the snowman and also select which specific parts are rendered.

Specifically, the snowman should consist of a body, two branch-like arms, a top hat, and a carrot nose.

The body should be made of three stacked spheres, getting progressively smaller going up. I want to be able to control the overall height. The base of the body should have a flat bottom where the bottom sphere is cut-off so it can rest on a surface. There should be some simple circular indents for eyes and mouth. There should also be a small flat section on the middle sphere for the arms to attach to.

The arms should look like branches, not just cylinders. They should come out of the mid-section of the body. I'd like to be able to render them individually or with the whole snowman.

The hat should be a simple top hat with a cylindrical base and a wider, flat brim.

The nose should be a cone shape. I'd like it to be positioned on the face, pointing outwards.

I also need the ability to render a preview of the assembled snowman and another preview of the snowman with all parts exploded, like they are in different positions and not overlapping.

I'd like to have an option for render quality, maybe just two settings: "Draft" and "Production," where "Production" uses a higher `$fn`.

Could you please create the necessary .scad files for this project? I don't have any existing code or specific libraries in mind, so I'll need everything from scratch.

Hey, I'm looking to design a laser-cut card holder, and I'd like a parametric OpenSCAD file (or files if it makes more sense that way) to generate the design. It's basically a base with two upright supports, and I need to be able to adjust the dimensions of pretty much everything.

Here are the specifics:

*   **Material:** I'll be using wood and acrylic, so I need a way to specify the material thickness. I'd like to also add some tolerance to the slots to accommodate for kerf.

*   **Base:** The base will have a rectangular footprint and two sets of slots cut into it; these slots will hold the supports. I need to define the total width and depth of the base, as well as the number of slots for each support, and the amount of "buffer" space on all sides of the base. These buffers will mostly be to account for material width issues. Each slot should take a fixed proportion of the total base depth.

*   **Supports:** There will be two upright supports, each with a series of "fingers" that slot into the base. These supports will be at different heights and will have a different number of fingers, so those need to be adjustable parameters.

*   **Angled Sides:** The uprights will attach to angled "lateral" supports that start at the base and angle upwards to meet the sides. These pieces form the structural integrity of the overall object. I need to be able to adjust the angle of these lateral supports. The connections between these sides and the supports needs to also include tolerance. Also, I'd like a small lip added to the edge of the lateral supports to provide some additional stiffness. Finally, I'd like each slot along the base to have a small "tab" at the end that provides some additional stiffness.

*   **Corner Rounding:** I'd like to be able to define a radius for all internal and external rounded edges.

*   **Stress Relief:** Given this is going to be cut on a laser, I need some stress relief around corners.

In summary, I'd like the following parameters to be configurable:

*   `thick`: Material thickness.
*   `reserva`: Buffer space on all sides of base.
*   `width`: Total width of the base.
*   `extra`: Extra space to increase the overall length.
*   `height_1`: Height of the first support.
*   `height_2`: Height of the second support.
*  `qt_slot_1`: Number of slots in the base for the first support.
*   `qt_slot_2`: Number of slots in the base for the second support.
*   `between`: Distance between the two sets of slots in the base.
*   `base_slot`: The proportion of the total depth that is occupied by each slot along the base.
*   `neck`: Additional height for support stiffness
*   `theta`: The angle of the lateral supports.
*   `radius`: Corner rounding radius.
*   `fit`: Kerf tolerance for slots.

It would be great if you could generate a well-commented and easy-to-modify OpenSCAD file or files using those parameters. No libraries are necessary unless you think it will make your work easier. I would also prefer to avoid using functions if possible.

I'm looking to design a tool to help with filament changes on my 3D printer, specifically a Makerfarm i3v. I'd like it to be parametric so I can easily tweak it for different needs.

Essentially, the tool is a block with a stepped profile and a hole through it. The main body of the tool should be a rectangular block with rounded corners. I'd need to control the following:

*   **Body Thickness:** How thick the main block is (default should be around 5mm, range from 3 to 8 mm).
*   **Body Width:** The width of the main block (default about 10 mm, range from 5 to 15mm).
*   **Body Length:** The length of the main block (default around 35mm, range from 10 to 50mm).
*   **Step Height:** The height of the step at the back (default 4.5 mm, range from 0 to 6 mm).
*   **Step Offset:** How far the step extends along the length of the block (default 8mm, range from 0 to 15mm).
*   **Hole Diameter:** The diameter of the hole through the tool (default 4 mm, range from 0 to 8 mm).
*   **Hole Offset:** Distance of the hole from the end of the tool (default 5 mm, range from 0 to 15mm).
*   **Corner Radius:** The radius of the rounded corners of the main block (default 2mm, range from 0 to 10mm).

The step should start at the top edge of the main block and extend outward with a 45 degree angle and a short flat top. The hole should pass all the way through the block on the opposite end from the step.

I'd like the OpenSCAD file to use the `minkowski()` function to create the rounded corners.  Could you generate the necessary OpenSCAD file(s) for this?

I'd like to create a parametric furniture riser with rounded corners. I need it to have a wider base than the top, and a lip at the top to help keep the furniture from sliding off.

Specifically, I want the following parameters:

*   `steps`: Controls the number of extrusion steps to create the sloped sides.
*   `relief_thickness`: Controls the thickness of the lip at the top.
*   `relief_height`: Controls the height of the lip at the top.
*   `height`: Controls the overall height of the riser.
*   `bottom_width`: Width of the base.
*   `bottom_length`: Length of the base.
*   `bottom_corner_radius`: Radius of the rounded corners at the base.
*   `top_width`: Width of the top.
*   `top_length`: Length of the top.
*   `top_corner_radius`: Radius of the rounded corners at the top.

The riser should smoothly transition from the base dimensions to the top dimensions using linear extrusions, then include the lip at the top. All of this should use rounded corners. It should be designed to be 3D printed.

Could you generate an OpenSCAD file to do this? I don't have any specific libraries in mind, so whatever makes the most sense would be fine.
