Hi, I'm looking to create a custom leg component for a small robot project. I've got a good idea of what I need, but I'm not great at OpenSCAD, so I'm hoping you can help generate the code.

The leg consists of three main parts: a central body with a rounded corner, and then two endcaps that attach to the top and bottom of that body. Each of the endcaps needs a hole that goes through the leg for an axle, and a cutout to accept a small servo rotor.

Here are the specifics:

**Central Body:**

*   I want a rounded, or filleted, corner on this part. I'd like to define the fillet radius as a parameter. There will be a kind of "inverse fillet" on the other side of that corner, and that radius should be the same as the fillet.
*   The central body has two different width measurements. Let's call these `top_width` and `bottom_width`.
*   It also has a height for each of these widths, `top_height` and `bottom_height`.
*   The hole for the axle should also have a parameter for the radius `axle_radius`, and I also want to specify how much extra padding is around that hole to reach the edge of the body, `axle_padding`.
*   There needs to be a cutout for the rotor, and this cutout has a few measurements:
    *   `rotor_width`
    *   `rotor_length` (center to center of circles)
    *   `rotor_height` (this will be the depth of the cutout)
    *   The cutout shape is essentially two circles, each with a `rotor_width` diameter, joined with a `hull()`
    *   One of the circles should be the same diameter as the axle, `axle_diameter`, or `axle_radius*2`.

**Endcaps:**

*   The endcaps will have the same thickness as their respective height on the central body.
*   They also need the same axle hole with radius `axle_radius` and the same padding `axle_padding`.
*   They need the rotor cutout similar to the one on the central body, but I will set the depth of this to match the `rotor_height`.
*   The main shape of the endcap needs to attach to the main body at the `top_width` (top endcap) and `bottom_width` (bottom endcap), and extend the width out to be flush with the outside of the axle padding.

I'm thinking we'll need a few modules: one to create the rounded/filleted corner, one for the main body, and one for each endcap. Also, the central body is a good starting point for the endcap parts, which I think we can use as a base and then apply some transformations to orient them as needed.

I would like to use the `hull()` function for creating the rotor cutouts, and I also want to make sure to use `linear_extrude()` where it makes sense. Also, I think that it would be helpful to use variables throughout, and to use comments, especially when parameters are being defined. I'd also like to define `$fn` for the circle and cylinder segments.

I think that about covers it. Let me know if you have any questions. I don't think I need anything from a library, but if there's something that would be helpful, let me know. Thanks!

I need an OpenSCAD design for a 9V battery holder, basically a box with a clip to hold the battery in place. The battery dimensions I'm working with are 26mm tall, 16.75mm deep, and 44.8mm long, with the terminals on the left side when the battery is lying on its short side. I'd like the box to have a wall thickness of 2mm.

It should also have the option for two small, alignment "slot" protrusions on one of the long sides to help with positioning the holder. These protrusions should be 19mm wide and 6mm long, and they need to be centered on the side, one above and one below the midpoint of the vertical axis. These should be optional with a toggle variable.

I'd like it to have a retaining clip on the left side (the terminals side) to help keep the battery from falling out.  The clip should stick up about a third of the height, and the clip should only come up over the bottom edge by 2.02mm and not obstruct the terminals.

Finally, the box itself should be hollowed out to fit the battery snugly, so there's an internal void with the exact dimensions of the battery (not including the clip or slots). And, I'd like the battery cavity to have a small set of guide tabs in the clip area at 1/3 and 2/3 height that are roughly 2mm wide and 0.5mm tall to help with alignment, but they shouldn't stick out more than 0.5mm from the inside walls of the box.

Could you make this a parametric design? I'd like to be able to change the battery dimensions, wall thickness, slot dimensions, and clip position easily.

```
// All measurements in mm
// Battery dimensions with it laying on it's short side, terminals to the left

battery_h = 26;  // height of battery
battery_w = 16.75;  // depth of battery
battery_l = 44.8;  // length of battery
shell = 2;  // thickness of box

slot = true;  // (bool) auto-centered slot alignment protrusions
slot_h = 19;  // width of "slot" protrusions
slot_w = 6;  // length of "slot" protrusions

difference() {
  union () {
    // Battery box:
    cube([battery_w + (shell * 2),
          battery_l + shell,
          battery_h + (shell * 2)]);
    // retainer clip
    translate([-.02, -1 * shell, (battery_h + shell) * .33])
      cube([shell * 2, shell + .02, (battery_h + shell) * .33]);
    if (slot) {
      translate([battery_w + shell * 2 - .02,
                (battery_l + shell) / 2 - (slot_w / 2),
                (battery_h + shell) / 2 - (slot_h / 2) - shell])

                (battery_h + shell) / 2 + (slot_h / 2)])
        cube([shell, slot_w, shell]);
    }

  }

Hey, I've got this idea for a customizable wax seal stamp, and I'd love your help creating the OpenSCAD code for it!

Essentially, I want a design that lets users specify the letters they want on the stamp, their angle, the depth, whether there should be a border around the edge and what the style of that border should be, and the border depth.

Here's a breakdown of what I'm imagining:

**Core Stamp:**

*   The stamp itself will be cylindrical with a handle extending up from the center.
*   The main face of the stamp will have the letters indented.
*   I'd like two letters, and the user should be able to specify what both of those letters are, or just one.
*   The letters should be centered on the stamp face.
*   The user should control the angle of the letters (a positive value would tilt the first letter counter-clockwise and the second letter clockwise), and the user should have a horizontal-letters option with a value of zero.
*   The user should also be able to control the depth of the letters/indentation.

**Border:**

*   The user should be able to choose if they want a border around the edge of the main stamp face.
*   If a border is chosen, the user should be able to pick between a circle or a square style of border.
*   The border itself would be made of several repeating elements arranged around the circumference of the stamp face.
*   The user needs to control the border's depth.

**Parameters:**

I need to be able to set the following through the customizer:

*   `first_character`: Text input for the first letter (default value: "W")
*   `second_character`: Text input for the second letter (default value: "S")
*   `text_depth`: Numerical input to control the depth of the letters. Use a range (0.5, 1.0, 1.5, 2.0, 2.5) with a default of 1.5.
*    `text_angle`: Numerical input to control the angle of the letters. Use 3.5 (angled letters) or 0 (horizontal letters) as choices with a default of 3.5
*   `show_border`: Dropdown menu with "Yes" or "No" options (default: "No")
*   `border_type`: Dropdown menu with "Circles" and "Squares" options (default: "Circles", which should correspond to a numeric value of 0).  "Squares" should correspond to a value of 1.
*   `border_depth`: Numerical input to control the depth of the border elements.  Allow 0.3, 0.4, and 0.5 as choices with a default of 0.3

**Output:**

The final design should be a single solid object that is ready for 3D printing.  I'd like to keep the handle of the stamp separate from the face of the stamp.  This way, someone could use the core stamp and attach it to some other handle later.

Also, I'd like to use the `write()` module from the Write.scad library.

Could you generate the necessary OpenSCAD files for this? Let me know if you need any more clarification!

I'm looking to design a cable clip for my CNC mill, something that can hold motor and sensor cables securely and be screwed down. I'd like it to be parametric so I can adjust dimensions easily. I’ve attached the design notes from a previous version I found online which should give you a general idea of what I want. I really liked its customizability, especially the text options.

Essentially, it should be a clip with a cable channel running through it, with screw holes on either side for mounting.  Here's what I need:

*   **Basic Shape:** A main body with chamfered edges.
*   **Cable Channel:** A semi-circular channel running through the body to hold the cables, with a customizable diameter and depth.
*   **Screw Holes:** Two holes for mounting, with customizable spacing, screw diameter (for M2.5 or M3 screws), head diameter, and head depth. I'd like the screw holes to have countersinks or chamfers for the screw heads.
*   **Text:** I need the ability to add text to the top of the clip, either embossed or added on as a separate object. The text size and depth should be customizable, along with the text itself.
*   **Customizable dimensions:** The overall length, width, and height of the clip needs to be customizable.
*   **Libraries:** I will be using the `write/Write.scad` library for the text function.

Could you generate OpenSCAD code that meets these requirements? I think it would make sense to separate the text related code into the `write/Write.scad` file but I think you'll be creating that from scratch too, right? Also, I would like the main file to be named `cable_clip.scad` please. Thanks!

I'd like to design a parametric car wheel center cap using OpenSCAD. I have a few specific dimensions in mind and would like it to be easily customizable.

The basic design will be a cylindrical cap sitting on a cylindrical throat, which in turn sits on the wheel. The cap will have a defined radius and height, and the throat will have its own radius and height, both defined as outside dimensions. There will be a set of rectangular cutouts spaced around the perimeter of the throat to grip the wheel.

Specifically, I'm looking for the following parameters:

*   `Cap_Radius`: The radius of the top cap (outer dimension).
*   `Cap_Height`: The height of the top cap.
*   `Throat_Radius`: The radius of the cylindrical throat section below the cap.
*   `Grip_Height`: The overall height of the throat section (and thus, the wheel grips).
*  `Thickness`: This will determine the interior radius of both the throat and the cap, and create a uniform wall thickness.
*   `notch_offset`: The vertical distance between the top of the cap and the beginning of the angled notch leading to the grips.
*   `notch_height`: The radial height of the notch section, measured from the radius of the throat.
*   `Notch_Bevel_Height`:  The radial height of the bevel on the outer edge of the notch.
*   `Cut_Width`: The width of the rectangular cutouts around the throat.

The throat will extend past the cap's bottom edge, and there will be an angled or beveled section between the cap and the throat. The cutouts will extend through the throat and a bit into the cap's interior for proper wheel grip.  I'd like the cutouts to be evenly spaced at 90-degree increments.

I'd like to have the code to include a module for each main component (cap, throat, notch, cutouts) and a main module that assembles the final object. Please use `difference()` to cut out the negative spaces from the main body, and use `hull()` to generate the bevel for the notch. Don't forget a module to make the inner cutout. I'd also like `$fn=64;` to make the cylinders smooth.

I don't need any specific libraries, just the basic OpenSCAD modules.

I've got a super basic OpenSCAD file here, and I need help making it parametric and useful. All it does right now is start a `group()` with another empty `group()` inside it. It's from a FreeCAD export, so it's pretty much useless as is.

What I'm trying to do is make a generic, configurable box. I want to be able to define the overall external dimensions (width, depth, height) and the wall thickness. It should be a simple rectangular box with a lid that fits snugly on top. The lid should have the same wall thickness as the base. I don't need any fancy features, just the basic box and lid.

Can you generate the OpenSCAD code for this, using a single file with parameters for the external dimensions and wall thickness? I'd like to keep it relatively simple and easy to understand, without including any unnecessary complexity. Please ensure the lid fits properly by accounting for the wall thickness and clearance.

I don't have any special library requirements beyond OpenSCAD itself.

I'm looking to create a vase holder, something with a kind of rounded, pot-like shape and some decorative holes around the base. I'd like to be able to adjust the overall size easily.

Specifically, I want a design that's essentially a hollowed-out vase shape sitting on a base. The base should have a circular footprint, and also include four smaller circular holes evenly spaced around the perimeter.

The main body should start with a cylindrical section at the base, then gradually widen outwards in a curved fashion and eventually narrow again before reaching the top edge. The base should be solid. It might be easiest to create this using a series of linear extrusions with scaling. I'm picturing something like a stepped curve, rather than a perfectly smooth one.

The inside of the main body should be hollowed out, and the hollow should follow the general curve of the outer shape. I'd like to have the option to change the diameter at the base, so I would prefer to see a diameter variable at the top. I don't have a preference about the library used.

I'd like a parametric strap clip for backpacks, similar to the one described in the Thingiverse link, but I'd like to be able to control all of the dimensions. Specifically, I need to define:

*   The width of the straps that the clip will hold
*   The thickness of each of the straps individually, and they might be different (but if I don't need it, one strap's thickness should be able to default to the other's)
*   The size of each of the openings in the clip, again, they might be different sizes. (And similarly, one opening's size should default to the other's if desired)
*   The vertical position of each opening (as a percentage of the clip's height)
*   The overall length of the clip
*   The wall thickness of the clip
*   A general margin for error to give the straps a bit of room
*   The resolution of the curve generation

I need the clip to be designed in such a way that it can hold two straps, and that each strap enters through it's own opening. The clip should have rounded edges where the straps contact, and also smooth corners on the outside.

It also should be fully parametric, so I can adjust all these values. Please make sure it uses the BOSL2 library for its shapes since I'm already using that in other models.

Thanks!

Hi, I'm looking for some help creating an OpenSCAD file to generate custom wheel center caps with logos. I'd like it to be parametric so I can easily adjust the size and logo.

Here are the general specs I'm thinking of:

*   **Cap Shape:** The cap should be a circular disk with a rounded edge, like a fillet. It will also have an inner cylinder that fits into the wheel with some clips to hold it in place.
*   **Parameters:** I'd like to control the following dimensions through variables:
    *   `th`: Overall cap thickness.
    *   `id`: Inner diameter of the cylinder that fits in the wheel.
    *   `od`: Outer diameter of the cap.
    *   `slheight`: Height of the inner cylinder and clips.
    *   `logoName`: File name of the logo in STL format.
    *   `logoXoffset`, `logoYoffset`, `logoZoffset`: Offsets for positioning the logo.
    *  `logoXscale`, `logoYscale`, `logoZscale`: Scaling factors for the logo.
    * `NoSides`: Sets the smoothness of the circles.
*   **Logo:** The logo should be imported from an STL file and placed on the top of the cap. I need to be able to scale it and position it properly.
*   **Clips:** There should be some clips on the inner cylinder to provide a friction fit.
*   **Rounded Edge:** The outer edge of the cap should have a rounded fillet.
*   **Modularity:** It would be great to have the clips, logo, and fillet functionality as modules that can be reused if needed.
*   **Libraries:** I'm not sure if you will need any particular library but I have seen people using MCAD for similar projects

Could you please help me create this OpenSCAD file? I think having these modules will make it easier to manage.

Hey there, I'm looking to design a 3D printable gadget for my homebrewing setup. It's essentially a pipe holder that will hook onto the rim of a brew kettle or carboy, allowing me to direct hot wort smoothly down the inside wall of the vessel when transferring between containers. This is to prevent splashing and reduce the chance of off-flavors.

Here's what I envision:

*   **The core:** A curved pipe section that holds the transfer pipe (hose). This pipe section should have a radius of 1.25 times the inner diameter of the pipe it's holding, and a bend angle that can be adjusted, likely between 90 and 180 degrees.
*   **Hooking Mechanism:** It needs a couple of "legs" on the outside that will rest on the lip/rim of the vessel, plus a single inner "leg" that will rest against the inside wall of the vessel. These legs need to be adjustable in length, to handle different vessel lip thicknesses and geometries.
*   **Pipe attachment:** The curved part needs to be a half-pipe section (like a trough) for most of its length, so the hose can sit inside it without being completely enclosed, but there should be overlap sections at both ends with the full pipe profile to hold the hose securely in place.
*   **Parametric Design:** It's important that all of the dimensions are easily adjustable through parameters, so that I can tweak the design for different pipe diameters and vessel sizes. For example, I need to be able to adjust the thickness of the walls, the diameter of the pipe, the curve angle, the lengths of the straight sections of the pipe before and after the curve, the length of the overlap sections, the length of the outer legs, and the length of the inner leg. Also the rendering quality needs to be tunable with a parameter.

I think it could be helpful if the design was created in separate modules for each piece so it's easy to adjust.

I'm hoping you can create a parametric OpenSCAD file, or set of files, for this. I'm not too familiar with libraries, so I don't have any specific requests beyond not being tied to any particular version of OpenSCAD.

Let me know if you have any questions, thanks!

Okay, I'm looking to design a parametric pillow block for a linear rod, something similar to a half SC8UU block but with more customization options. I need it for a Prusa I3 Y-carriage. I've got a rough idea of the basic shape from a design I found, which I've included the code for. I want to be able to adjust not just the size of the bearing housing, but also the dimensions of the base plate, the mounting holes, and the zip tie channels.

Specifically, I need the design to be driven by the following parameters:

*   **`boltLength`**: The length of the bolt pattern on the base plate.
*   **`boltWidth`**: The width of the bolt pattern on the base plate.
*   **`bracketLength`**: The overall length of the base plate.
*   **`bracketWidth`**: The overall width of the base plate.
*   **`bracketHeight`**: The thickness of the base plate.
*   **`bracketScrewDiameter`**: The diameter of the mounting bolt holes.
*   **`bracketScrewHeadDiameter`**: The diameter of the countersunk area for the bolt heads.
*   **`bearingLength`**: The length of the linear bearing to be used.
*   **`bearingDiameter`**: The outer diameter of the linear bearing.
*  **`bearingOffset`**: The vertical offset of the bearing's center from the top of the base plate.
*   **`bearingThicknessOffset`**: The extra width added to the bearing block to allow for fitting.
*   **`bearingLengthOffset`**: The extra length added to the bearing block to allow for fitting.
*   **`squareRadius`**: The radius of the rounded corners on the base plate and bearing block.
*   **`rodDiameter`**: The diameter of the rod that the bearing slides on.
*  **`ziptieWidth`**: Width of the ziptie channel.
*  **`ziptieHeight`**: Height (or depth) of the ziptie channel.

The design should have these features:

*   A rectangular base plate with rounded corners.
*   A rectangular block on top of the base plate that houses the linear bearing, also with rounded corners.
*   A cylindrical hole through the bearing block for the linear bearing.
*   A cylindrical hole through the bearing block for the linear rod.
*   Countersunk screw holes for mounting the base plate.
*   A recessed channel for zipties to secure the bearing block.

I'd like the design to be fully parametric, so I can easily adjust any of these values. It would also be helpful if the bearing block height was calculated based off of the other parameters, similar to how it was done in the code I provided, rather than requiring a separate user parameter. I'm expecting the output to be a OpenSCAD file, or multiple if that would make it more modular. I’m not asking you to improve the code I sent, as it works for demonstration purposes, but I need a completely parametric solution. I do not want to use MCAD or BOSL.

I'd like to design a dog tag shaped like a bone in OpenSCAD, but I want it to be parametric so I can easily change the size, text, and other details. I'm envisioning a bone shape created from cylinders for the ends and a cube for the center portion, all joined together. I'd like the text to be extruded and placed on the bone, one line for the pet's name and another line with the phone number. I'll also need a hole for attaching it to a collar or keyring.

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

*   **bone\_height**: This will control the thickness of the tag.
*   **pet\_name**: The pet's name, which will be displayed on the tag.
*   **phone\_number**: The phone number, also displayed on the tag.
*   **font\_face**: I need to be able to change the font. It's really important this is a monospaced font or the text will not center correctly.
*   **font\_thickness**: This will be how high the text is extruded.

The text should be centered as it currently is in the file I'm referencing. The attachment hole should be at one end and I would like the cut to be made as a 'difference' to avoid the non-manifold errors I'm currently seeing. I'm not using any libraries currently, but I'm open to using them if they'd help. I'd like all the code to be in one .scad file please.

Hi, I'm looking to get a parametric fingerwheel designed in OpenSCAD. I've got some basic dimensions in mind, but I want to be able to easily tweak them. I need it to have an overall cylindrical shape with a few different features.

First, it needs an overall outer diameter and total height, which I'd like to control via variables. Then I need to make it so I can cut out a recessed area on the bottom using two different diameters and the height of this recessed cut. I also need to put a through-hole in the center.

Next, there should be a shoulder on the top that I can define with two different diameters at the top and bottom of the shoulder, as well as its height. After this, I'd like to add a hexagonal cut-out on top of the shoulder, and I should be able to control its width and depth.

Then, around the perimeter, I want to add a number of grip notches, basically by subtracting cylinders, that I can control their radius, depth, and how many of them there are.

Finally, I'd like to have a chamfered edge on both the top and bottom of the fingerwheel, each with its own height controlled by a single variable.

I don't have a specific library preference for this one; I'm fine with whatever you think is easiest to work with. Let me know if you have any questions, but I think I've given you a pretty good starting point.

Hey there, I'm looking to design a parametric adapter for my pen holder, specifically for holding a stylus. I've got a few key dimensions in mind, and I'd like to be able to adjust these easily.

Basically, I need a cylindrical adapter that will fit inside my pen holder. This adapter needs to have a hole going through it to hold the stylus. I'm going to call this the "stylus mount."  The outside diameter of the adapter and the height of the adapter will need to be adjustable, as will the diameter of the hole for the stylus. I'd also like to include a little cutout in the side of the cylinder for some flexibility, and a hole perpendicular to the main stylus hole for a small screw.

Here's what I'm thinking for parameters:

*   **`stylusDiameter`**: The diameter of the stylus itself.
*   **`tolerance`**: A tolerance value to add/subtract from diameters.
*   **`mountDiameter`**: The outer diameter of the adapter that will fit inside my pen holder.
*   **`mountHeight`**: The overall height of the adapter.
*    **`spaceSize`**: The size of the cube cutout on the side of the adapter.

The main body should be a cylinder defined by `mountDiameter` and `mountHeight` and a `tolerance` value should be subtracted from it's radius. Then I'd need a cylindrical hole to go all the way through the adapter's center. The diameter of the hole needs to be equal to the `stylusDiameter` plus the tolerance. Then I want a little rectangular cutout on the side, a small cube, that I'd like to call `space`. Lastly, there needs to be a hole for a 3mm screw, perpendicular to the stylus hole. The diameter of this hole should be 2.6mm.

I think that's it for now. Can you generate the OpenSCAD code for that, so I can test it out?

I'm looking to create a customizable bin system similar to the removable compartments in a Harbor Freight parts organizer. I've seen some designs out there for Stanley organizers, but the dimensions are different, so I need a new design. I'd like the design to be parametric, so I can adjust the number of compartments and the overall size.

Specifically, I need to be able to control:

*   **Number of slots:** I want to be able to specify the number of vertical and horizontal slots (like a grid).
*   **Number of dividers:** I need to specify how many internal dividers there are horizontally and vertically, creating sub-compartments.
*   **Case height:** I'd like to be able to choose between a shallow or deep case version using the same code.
*   **Skirt:** I'd like to have an optional skirt around the base.
*   **Wall thickness:** I want to be able to set the wall thickness.

The design should use the following as a starting point for the single and double compartment dimensions, as well as the spacing between those compartments:

*   **Single compartment height:** 52.25mm
*   **Double compartment width:** 77.1mm
*   **Double compartment height:** 107.4mm

The internal spacing is derived from the difference between the double and single compartment dimensions, which needs to be calculated in the code (rather than being explicitly set).

Additionally, the case should have rounded corners and feet. I want to specify a radius for the rounded corners and a height and size for the feet.  The feet should have an optional skirt.

It would be great if you could generate a single OpenSCAD file that uses the MCAD library, specifically `boxes.scad`.  It shouldn't be hardcoded for a specific number of slots/dividers/heights.

I'd like to design a combination lock with rotating dials. I have a design concept, but I need an OpenSCAD file (or files) to generate the parts.

Here's what I'm going for:

*   **The Basics:** The lock should have four rotating dials, each with the numbers 0 through 9. Each dial should have a small 'gate' that, when aligned correctly, allows the lock mechanism to open.

*   **Dial Design:**  Each dial will essentially be a cylinder with a hollowed-out center and a lip on both the front and the back. The numbers will be printed around the outer edge of each dial and slightly raised. When viewed from the side, the hollowed-out center of the dial will be partially blocked off (similar to the geometry of the code example) by a cube-shaped 'gate'. The 'gate' should be inset relative to the edge of the inner hollow of each dial.

*   **Combination Setting:** The user should be able to define a 4-digit combination using variables `numberOne`, `numberTwo`, `numberThree`, and `numberFour`. Each of these will represent one digit of the final combination from 0-9 and each dial will rotate to a position determined by `rotationOne`, `rotationTwo`, `rotationThree`, and `rotationFour`, calculated as `180 - (number*36)`. The rotation should align the 'gate' within each dial to the correct position.

*   **Assembly:** I am imagining that the dials will be placed side-by-side, each in its own shell. The mechanism will need to fit onto some sort of frame which provides the necessary space for the mechanism to align when the correct combination is entered. The specific details of the shackle and frame are not a part of this ask.

*   **Parametric Design:** It's really important that the dial design and combination setting are fully parametric. I want to be able to change the dial dimensions, gate size, number size, and combination easily through the variables in the OpenSCAD file.

For any libraries needed, I think I'd be happy using BOSL2, or any other well known OpenSCAD library to generate the parts.

Hey, I'm looking to design a customizable fan nozzle/duct in OpenSCAD, similar to the one described in the fan_nozzle.scad file I'm attaching. I need it to be highly parametric so I can easily adjust it for different fan sizes and output requirements.

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

**Nozzle Body:**

*   `nozzle_length`:  The length of the main nozzle body (in mm).
*   `nozzle_wall`: The thickness of the nozzle wall.
*   `nozzle_tilt`: The tilt angle of the nozzle body (in degrees).
*   `nozzle_extension`: The length of the base extension from the fan mount.

**Output Hole:**

*   `nozzle_dillation`:  The size (diameter) of the output hole.
*   `nozzle_scale`: The ratio of height/width of the output hole. For example, 0.5 would result in a horizontally squashed shape.
*   `nozzle_edges`: Number of sides/corners of the output hole.  (3 for triangle, 4 for square, etc.)
*   `nozzle_edgeradius`:  Curvature radius of the output hole corners.
*  `nozzle_edgerotate`:  Boolean to rotate the nozzle output such that either a corner or a flat side is pointing directly upwards.
*   `nozzle_end_tilt`: Tilt angle of the output hole relative to the nozzle body (in degrees).

**Base (Fan Mount):**

*   `base_thickness`:  Thickness of the base (0 for no base).
*   `inlet_inner_diameter`: Inner diameter of the nozzle inlet (where the fan attaches).
*   `mntholes_diameter`: Diameter of the mounting holes/pins.
*   `mntholes_radius`:  Distance from the center of the nozzle to the center of the mounting holes/pins.
*   `mntholes_angles`: A list of angles (in degrees) for the mounting holes/pins around the base.
*   `pin_length`: Length of the mounting pins (set to 0 for holes instead of pins).

I'd also want to use `$fn` to control the smoothness of curves, but I'll handle that myself.  I also understand I need to import a fan STL, but I'll handle that myself too. I'd like to have the option of using mounting pins or just holes on the baseplate.

I'm not looking for anything too fancy, just a good, solid, parametric nozzle generator.

For this design, please use the standard OpenSCAD library. I don't need any additional libraries.

I'd like a parametric OpenSCAD design for a holder for a small, rectangular remote control, similar to the one I use for LED strip lights. It should be a relatively simple design that can be attached to a surface using double-sided tape.

The holder will consist of a main body that the remote slides into, and a clamping mechanism that secures it. I'll need to be able to adjust the key dimensions: the height, width, and depth of the remote itself.

The main body should have a flat back and a "U" shaped front profile with a raised portion, where the remote sits on. To provide a more secure hold I'd like to include 4 clamping blocks or "enforcements" that can be positioned horizontally. These blocks should be small, reinforced cubes which can be placed anywhere along the vertical length of the remote. I would like a value to define their horizontal location as a percentage (0 to 1) of the holder's length. In addition to the clamp blocks, i'd like an optional clamp at the top of the holder, and clamps along the sides, which can be set to any depth.

I'll need parameters to control the width of the clamps, the depth of the clamp plates, and the depth of the notch on the clamp plates. I'd like the side clamps to come up the sides of the main holder.

I think that covers everything. If it helps, here's a visual explanation: imagine a remote control sitting vertically, then the holder has a u-shape that wraps around the front and sides, a clamp sits on top to prevent it from falling out, and clamps that come in from the sides.

[Assistant]

I'm looking to create a customizable gift box using OpenSCAD, similar to the one I've seen on Thingiverse. I need it to be parametric, so users can easily adjust the dimensions, and I want the design to include a top, bottom, and a ribbon that goes around it.

Specifically, I want the following parameters to be adjustable:

*   **Box Dimensions:**
    *   `Width` (in mm)
    *   `Depth` (in mm)
    *   `Height` (in mm)
*   **Wall Thickness:**
    *   `WallThickness` (in mm) - This should ideally calculate automatically based on the smallest of Width and Depth, but I want to be able to manually override that. Let's say if the user inputs -1, calculate as BaseDimension * 0.06.
*   **Clearance:**
    *   `Clearance` (in mm) - Distance between the lip of the top and the inner walls of the bottom.
*   **Ribbon Dimensions:**
    *   `RibbonWidth` (in mm) - again, auto-calculate if set to -1 (BaseDimension/5)
    *   `RibbonThickness` (in mm) - again, auto-calculate if set to -1 (BaseDimension/40)
    *    `RibbonDiameter` (in mm) - again, auto-calculate if set to -1 (BaseDimension*.18)
    *   `RibbonSize` (in mm) - This will control the total width of the ribbon bow. If set to -1, calculate as BaseDimension*.45. Should be halved for use in calculations.
    *   `RibbonEnd` (in mm) - Length of the ribbon ends. If -1, calculate as BaseDimension*.35.
*   **Other:**
    *   The height of the top (`HeightTop`) should be a quarter of the overall box height, and the bottom (`HeightBottom`) should be the remainder.
    *   There should be a lip on the top that fits inside the bottom, controlled by the `LipHeight`.
    *   The ribbon cutouts should be calculated and located correctly.
    *   There should be fillets and chamfers to avoid sharp edges, with a user-definable `FilletRadius` and `ChamferSize`.
    *   The ribbon should consist of two parts that can be printed flat and assembled.
    *   The ribbon should be slightly thinner at the portion that intersects the box to enable printing and allow for some clearance of printing imperfections.

I’d also like the design to include different view options: "bottom" (bottom piece only), "top" (top piece only), "ribbon1" (first ribbon part), "ribbon2" (second ribbon part), "ribbon" (both ribbon parts combined), "all" (all parts laid out on one build plate) "exploded" (all parts separate, offset for better visibility), and "assembled" (all parts assembled).  The selection of which view should be rendered can be controlled via a variable called "part."

I'd appreciate it if the code used best practices and was well-commented, so it's easy for others to understand and modify. Please do not use any external libraries, I need it to be a single scad file.

Thanks!
