Hey! I'm looking to create a parametric design for a sauce packet organizer, something that can hold those flat, single-serve condiment packets. I've got some specific ideas, and I'd like to be able to customize the design through parameters.

Basically, I want a box-like holder with an open top, sized to fit a standard ketchup packet (about 51mm wide and 90mm long). The height should be customizable, but let's start with something like 180mm. I need to control the wall thickness too, maybe start with 2.8mm.

I'd like a ramp at the back of the holder, inside at the bottom, to help bring the sauce packets forward. The ramp should be a certain percentage of the packet length (maybe 60% initially), and also adjustable for ramp height (say, 15mm).

Also, I want to have a lid that can slide over the top of the holder. The lid should have a depth of 3mm, and I’d like a parameter to let the lid cover or not cover the side connector if present.

I need the option to add connector locks on the sides of the holder, so I can link multiple organizers. I want to be able to control whether a lock appears on the left side, right side, both sides or none. The connector should be a trapezoidal shape, where the width at the top is about 5mm, and the depth around 2mm, I also want a parametric value that adjusts the tightness of the trapezoidal joint.. I need that tightness to also affect the lid slide fit, ideally a single `SlideTightFit` parameter.

I'll also need the option to add text labels, for the front of the main holder, and for the lid, with parameters for the text, font size, and position. On the front of the holder, I'd like to add a label at the top, and potentially one in the middle. On the lid, I'd like to be able to specify a label along its short axis, and one along its long axis, with parameters for positioning on the lid and rotation for the long axis text.

I want all of this to be controlled parametrically in OpenSCAD, so I can tweak things easily. I'm thinking that it should be possible to render each component of the final object separately, or all together. I'd like to use a `PieceToRender` parameter to select what to render and a global `$fn` parameter to control mesh quality.

So, in summary, parameters needed:

*   `$fn`: mesh quality
*   `PieceToRender`:  0: All pieces, 1: Main holder, 2: Lid, 3: Connector lock, 4: Main and Lid printable, 5: All pieces printable
*   `Font`: text font
*   `FontSize`: text font size
*   `FontDepth`: how far text is extruded
*   `WidthOfPacket`: width of packet
*   `LengthOfPacket`: length of packet
*   `HeightOfHolder`: height of the holder
*   `WallThickness`: thickness of the walls
*   `Connectable`: 0: No, 1: Left side only, 2: Right side only, 3: Both sides
*   `FrontLabel_Top`: front label text, top
*   `FrontLabel_Mid`: front label text, middle
*   `IncludeRamp`: 0: No, 1: Yes
*   `RampPercent`: percentage of packet length for ramp
*   `RampHeight`: height of ramp
*   `LidDepth`: depth of lid
*   `LidCoversConnector`: 0: No, 1: Yes
*   `LidLabel`: label on lid
*   `LidLabel_Position`: 0: Font, 1: Middle, 2: Back
*   `LidLabel_LengthWise`: label on lid lengthwise
*   `LidLabel_LengthWise_Position`: 0: Bottom, 1: Middle, 2: Top
*    `LidLabel_LengthWise_Rotation`: 0: Left, 1: Right
*   `SlideTightFit`: the tightness of the sliding joint and lid fit.
*   `ConnectorDepth`: depth of the connector lock
*    `ConnectorTopWidth`: width of the top of connector lock.

I think that's everything.  I don't think I need to use any specific external libraries other than the built-in OpenSCAD functions. Thanks!

I want to design a sunglass holder that clips onto a car's air vent. It should have a ball-and-socket joint so the glasses can be positioned easily. I'd like to be able to customize it for different car vent fin widths and different sunglass temple (arm) sizes.

Specifically, the design should have the following features:

*   A cylindrical part that holds the sunglasses. The cylinder should be hollowed out to fit the sunglass temple.
*   A post extending from the side of the cylinder that acts as the "ball" part of the joint.
*   A socket to hold the ball, and connected to the vent clamp. The socket should have a small amount of clearance to allow the ball to move.
*   A clamp that fits over the car's vent fin. This should consist of two fingers extending from the socket part and gripping the vent.

I need the following parameters to be customizable:

*   `vent_fin_width`:  The width of the car's vent fin.
*   `length_of_fingers`: The length of the clamp fingers that grip the vent fin.
*   `inner_diameter`: The inner diameter of the cylinder that holds the sunglass temple.

I'd like the design to be in OpenSCAD, and I'd appreciate it if you could use the BOSL2 library because I'm familiar with it. I'd like to receive all the files necessary to create the design. I would prefer that everything be included in one file so it is easier for me to work with.

I want to design a customizable toilet paper holder, and I'd like it to be parametric so I can easily adjust the dimensions. I'm envisioning two main parts: an arm that holds the toilet paper roll, and a wall-mounted holder that the arm slots into. I'd like the ability to generate either just the arm or the holder separately.

For the arm, it should be basically a bent rod with a few key features. I need to be able to set the overall length, height, and diameter of the rod. The corners should be rounded with a configurable radius. I also want a cut-out on the bottom of the arm at one end. This cut-out will act as part of the locking mechanism, so it needs to have a configurable width and depth. Also the cut-out needs to have rounded corners to make the insertion smoother. I need to be able to mirror the arm so I can make left and right-handed arms.

The holder should have a mounting plate that attaches to the wall and a loop that holds the arm. I need to set the overall width, height, and thickness of the mounting plate. I should also be able to change the loop's width. There needs to be a corresponding notch on the inside of the loop for the arm's cut-out locking mechanism. The mounting plate should have configurable screw placements. I want to choose between no screws, screws on the sides, screws in the corners, or screws on the top and bottom. I will need to set the distance of the screws from the edges, the screw hole diameter, and the countersink angle and depth. The hole that receives the arm needs to have a slightly larger diameter than the arm itself for ease of insertion - this will also need to be a configurable parameter. I also need some fillet around the arm holder.

Ideally, this would be done in OpenSCAD and use parameters so I can change these dimensions easily. I don't have any code to start with, so you'll be creating all the necessary .scad files.

Toilet paper holder by Jkk79.
It started as a copy of something I have on my bathroom's wall and then expanded into fully customizable thing.
Well, originally, I broke the arm on the one I have and decided to print a replacement arm (it would have been faster and perhaps cheaper to just go and buy a new one), and then I thought that It would be cool to make the whole thing, but the holder part would be impossible to print with the original locking mechanism, at least without support structures, so I had to make my own design.

I'd like to design a parametric object that consists of three triangular forms arranged around a central point.  I've got some specific requirements.

Each form will be based on a 3D triangle, which is created by extruding a 2D triangle. The 2D triangle is essentially a circle with a smaller circle subtracted from it to make a ring, and with `$fn=3` to give it the triangle shape. I need to be able to control the diameter of the circle, the thickness of the ring, and the extrusion depth.

The key is the arrangement of the three triangles. They should be rotated around the z-axis, 120 degrees apart. Then they are translated outward along a line which begins on the circle, and rotated to lean inward. Finally, they should be rotated 90 degrees along the x-axis to point "up" or "outwards".

I need to control a few parameters:
*   `depth`: The extrusion depth of the 3D triangle.
*   `size`:  The diameter of the circle used to create the 2D triangle
*   `thickness`: The thickness of the ring making the 2D triangle
*   `lean`: The angle at which the triangles are rotated to "lean" inwards.
*   `div`:  A number used to calculate the distance of the translation of the triangles from the center. Specifically, the translation should be by a vector of (0, `size/div`, 0).

I'd like an OpenSCAD file that defines a `formGenerator` module that takes these parameters.  It should also define a `forms` module that includes a few example arrangements of these forms, each in a different color. I'd appreciate it if the `forms` module specifically includes an example where `div` is explicitly set. I don't need any libraries.

[Assistant]
triangle.scad:
```
depth = 2; //[1:10]
size = 30; //[10:100]
thickness = 5; //[1:10]
lean = -30; //[-180:180]
div = 7; //[1.5:10]

formGenerator(depth, size, thickness, lean, div);

//base 2D triangle
module triangle2D(dia = 20, thickness = 2) {
    translate([0,dia/2,0])
    rotate([0,0,90])
    difference() {
        circle(dia,$fn=3);
        circle(dia-thickness,$fn=3);
    }
}

//base 3D triangle
module triangle3D(depth = 2, size = 20, thickness = 2) {
    linear_extrude(height = depth , center = true, convexity = 10, twist = 0)
    triangle2D(size, thickness);
}

module formGenerator(d, s, t, l, div=2) {
    depth = d;
    size = s;
    thickness = t;
    lean = l;

    for (a=[1:3]) {
        rotate([0,0,(360/3) * a])
        translate([0,size/div,0])
        rotate([lean,0,0])
        rotate([90,0,0])
        triangle3D(depth, size, thickness);
    }
}

module forms() {

    translate([80,0,0])
    color("green")
    formGenerator(2,30,5,45);

    translate([0,80,0])
    color("lime")
    formGenerator(2,30,5,20);

    translate([80,80,0])
    color("red")
    formGenerator(2,30,5,20, 5);

    translate([-80,0,0])
    color("pink")
    formGenerator(2,30,5,-30,7);
}

Hey, I'm looking to create a customizable 3D model using OpenSCAD and I need some help getting started. I want a basic rectangular prism (a box) where all three dimensions can be adjusted using the customizer.

Here's what I'm thinking for the customizer options:

*   **X Dimension:** A dropdown menu with values like 1, 5, 10, 15, 20, and 25.
*   **Y Dimension:** Another dropdown menu, but this one should have text labels associated with each value. Something like "1:small", "5:medium small", "10:medium", "15:medium large", "20:large", and "25:extra large".
*   **Z Dimension:**  A slider that allows the user to select any value between 1 and 25.

I'd also like to include a few other customizer items to demonstrate functionality, like:

*   A text box (shouldn't affect the object, just there to display text).
*   Another text box, same as the first.
*   A number dropdown with values from 0 to 10.
*  A text dropdown with options "yes", "no", and "maybe"
*   A labeled dropdown similar to the Y dimension, but this one should have options like "1:small", "5:medium", "10:large", and "50:supersized".
*  A numerical slider going from 0 to 10.

It would be great to include a "build plate" for reference in the viewport. I want a dropdown to select from common printer build plate sizes, and an option for a manual setting where I can define the X and Y dimensions. I've got a list of options to pick from: Replicator, Replicator 2, Replicator 2X, Replicator (5th Generation), Replicator Mini, Replicator Z18, Thing-O-Matic, Cupcake CNC, Afinia H480, Afinia H800, AW3D HD, B9Creator, Robox, Bukito, Bukobot V2, Form 1, Form 2, hyrel, Creatr, Xeed, TAZ, TAZ Mini, Makergear M2, Printrbot Plus, Printrbot Simple Kit, Printrbot Go small, Printrbot Go medium, Printrbot Go large, and Diamond Age Moa. "Manual" will be another option. If the user selects manual, then we need the ability for them to input values for manual build plate x and y, using sliders between 100 and 400.

Finally, I'd like to add a unit conversion feature. The user should be able to enter the units they are designing in and the desired output units from dropdowns. For design, the options should be mm, cm, meter, inch, and foot. And for output they should be mm, cm, meter, inch, and foot.

The final object should take into account the unit conversions before it's drawn, so it's properly sized for 3D printing or whatever else it needs to be used for.

I need the build plate to be a distinct module that can be re-used in other files, so put that into a file called build_plate.scad and use an include statement.

So to summarize I need:
* A .scad file called template_including_unit_conversions.scad that is the main file
* A .scad file called build_plate.scad that includes the build plate module described above.

Thanks in advance for your help!

Okay, I need a parametric OpenSCAD design for a box base that will house an Arduino board and a joystick. I've got some specific dimensions and configurations in mind that I need to be adjustable. I'll be using this to 3D print it.

Here’s what I need:

*   **Overall Shape:** The main shape is a rectangular box with rounded corners, and a hollowed out interior. The exterior of the box needs to have a groove running along its sides to allow it to interlock with a top half.

*   **Dimensions:**
    *   The length of the base (`L`) should be adjustable, with a range from 130mm to 180mm.
    *   The width (`l`) should be adjustable, with a range from 90mm to 150mm.
    *   The height (`h`) should be adjustable, with a range from 35mm to 60mm.
    *   The wall thickness ( `e` ) of the base should be 4mm, and the corners should have a radius of 2mm. The inner cavity should follow the outer box shape and its dimensions be automatically calculated based on these values.

*   **Mounting Holes:** There need to be four mounting holes for screws at the corners of the base. The hole diameter should be adjustable to fit different screw types. I'd like to have presets for three screw types: "A", "B", and "C", but I need to know what those are (maybe you can generate them based on my dimensions here?). Let's assume screw type "A" for now, and use a hole diameter of 1.45mm with a corresponding head diameter of 5.6mm and a height of 1.65mm. The screw heads should be recessed.

*   **Side Grooves:** There should be grooves or slots ( `pt` depth of 5mm) around the perimeter of the base to allow for interlocking with another part. The grooves should be 0.5mm in radius.

*   **Arduino Mounting:** The design should accommodate an Arduino board. The coordinates of the four mounting pins for the Arduino are calculated from a base point and offset using some given math from the provided file. These need to be adjustable based on whether the design is for a "droitier" (right-handed), "gaucher" (left-handed), or "ambidextre" (ambidextrous) configuration, and should account for the Arduino being raised off the bottom of the base by a few mm (variable "hrc"). It should use 1.59mm diameter pins for support and have some extra material around the pins to give them enough resistance during prints.

*   **USB Cable Pass-through:** There should be a pass-through for a USB cable on one side of the base. The hole should be roughly 5.5mm high, 2mm deep and 1.5mm in radius.

*   **Joystick Mounting:** There is a basic representation of a joystick mounting which needs to be added but I need a simpler version as it is only an placeholder. This should be a simple cylinder of a given diameter and height.

*   **Parametric Design:** All of these dimensions should be parameters so I can easily modify them without having to edit the code directly.

*   **Libraries:** I need to use the `arduino.scad` and `K.scad` libraries.

Could you please generate the necessary `.scad` files for this? Please be as detailed as possible and assume I have little OpenSCAD experience.

[User]
Okay, I'm looking to design a two-part enclosure, and I'd like to start with the top part. This top will house an Arduino board and a joystick. I'd like this to be parametric in OpenSCAD, so I can easily change the dimensions later.

Here are the basic requirements:

*   **Overall Shape:** The main body will be a box with rounded corners using the minkowski sum with a sphere. I'll need to be able to specify the overall length (L), width (l), and height (h) of the box. The walls of the box should have a thickness (e).
*   **Internal Cavity:** Inside the box, there should be a cavity of equal wall thickness.
*   **Material Thickness:** The thickness of the top should be (e).
*   **Corner Rounding:** The edges and corners of the box should be rounded using Minkowski sums. I also need to be able to modify the sphere radius (s) used for this.
*   **Mounting Trenches:** I need trenches on the sides of the enclosure to join the top and bottom parts of the enclosure. The trench should have a depth (ht), rounded corners (s2).
*   **Mounting Holes:** I need four mounting holes for screws. I need to be able to control the radius of the screw hole (rv). The holes should be countersunk.
*   **Corner Pieces:** I need to add corner pieces to add thickness to the model.
*   **Joystick Mount:** There should be a hole for a joystick. This should be placed in either a center, left, or right-handed location. The location should be defined by variables (Lj, lj, and rj).
*   **USB Cable Slot:** I need a slot for a USB cable to exit the enclosure, on a side. I need to be able to control the slot depth (hfc).
*   **Jack Ports:** I need to be able to create holes for audio jacks on the side of the case. For the jack ports, I need holes to accommodate a female jack and a separate hole for a washer. The coordinate of the ports should be controlled with a variables.

I'd also like to specify the overall design mode as "droitier" (right-handed), "gaucher" (left-handed), or "ambidextre" (ambidextrous) as a variable. This should affect the joystick and audio jack placement.

I am using the K.scad library for the logo. Please generate a .scad file for this.

I'd like to create a customizable pendant design in OpenSCAD, something I can easily tweak for different shapes and text. I want the main body of the pendant to be either a circle or a rectangle.

For the circle option, I need to specify the radius. For the rectangle, I need to specify both length and breadth. The pendant should also have a thickness that I can control.

I also want to add text to the pendant. I need to be able to specify the text content, its size, the font used (using any font available), and the text thickness. It would also be nice to have options for text spacing, text twist (rotation), and horizontal/vertical alignment (like center, top, baseline, etc.). The text should be centered on the pendant.

Finally, I want to add a keychain loop at the top. I need to specify the height of the loop, its outer diameter, inner diameter and position the keychain relative to the pendant with X, Y and Z offset values.

Could you generate the OpenSCAD files for this design? Make sure the code is parametric so I can easily change all those values. I don't need any special libraries, just standard OpenSCAD functions.

I need some help designing an OpenSCAD file for a print that will help me check my printer's backlash settings. I want to be able to test this across the entire print bed, so I need a parametric design that lets me specify the number of test circles to print in the X and Y directions.

The basic idea is to print a grid of flat circles, each connected by a thin line. This way, the print head moves in a continuous path across the entire print bed, and any inconsistencies in the movement should be visible in the printed circles. Each circle should be approximately 2.5 cm x 2.5 cm, and the overall print should be 0.4 mm thick with lines that are 0.7 mm wide. I'm not sure exactly how to calibrate backlash from this, but it should be useful for checking consistency.

Here's a more detailed breakdown of what I'm envisioning:

1. **Circles:** Each circle should be a flat cylinder with a diameter of 15 mm and a height of 0.4 mm. There should be a smaller, 13.6 mm diameter cylinder subtracted from the center to create a thin ring. Additionally, there should be a rectangular cutout on each circle. This cutout should be made by rotating a 7.5 mm x 2.5 mm x 0.4 mm rectangular cube by 135 degrees and subtracting it from the ring.

2. **Connectors:** The circles should be connected by a series of thin, rectangular prisms. These connectors should form a continuous path that connects all the circles in the grid. They should run between the circles both horizontally and vertically to create the grid pattern. The rectangles should be made of the following:
    *   A horizontal rectangle along the bottom of the circle connecting it to the next circle.
    *   A vertical rectangle along the left side of each circle.
    *   A horizontal rectangle connecting each circle to its horizontal neighbor.
    *   A vertical rectangle along the right side of the rightmost circle in each row, connecting it to the circle in the row below.

3. **Parameters:** The design should be parametric, allowing me to specify the number of circles to generate in the X and Y directions using variables (e.g., `nox` for the number of circles in the X direction, `noy` for the number of circles in the Y direction). The distance between each circle should be 25 mm.

I'm using a printer with a 0.35 mm nozzle, but I'd like the design to be adaptable to other nozzle sizes if possible. I know slicing might be tricky since the print is so thin, so any advice on that would be appreciated. Also, my print bed needs to be very well-leveled for this to work.

Could you help me create an OpenSCAD file that implements this design? I don't need any external libraries for this, everything should be achievable with built-in OpenSCAD functionality.

I'm looking to create a parametric screwdriver design in OpenSCAD. I want the ability to switch between a Phillips head, a flathead, and a hex head bit, and I want to be able to adjust the overall scale of the screwdriver. I also need to be able to add a short text label on the handle.

Specifically, the design should have these features:

*   **Bit Selection:** The design needs to have the ability to easily switch between different bit types: a Phillips head, a flathead, and a hex bit. Only one bit should be active at a time. I want to control this using parameters, so I can choose which bit type to render.
*   **Scale Adjustment:** The overall size of the screwdriver should be adjustable using a single scale parameter, which affects the entire model.
*   **Text Label:** There should be a space on the side of the handle where I can add a short, user-defined text label, probably limited to 15 characters. It should be raised text, not engraved.
*   **Basic Geometry:** The screwdriver will consist of a cylindrical rod, a handle, and the chosen bit. The handle should be roughly cuboid with rounded edges, and the rod should be centered on the handle.
*   **Rotation:** The entire design should be easily rotated to the proper print orientation with a single rotation, before printing. The rotation should be [0,0,90].
*   **No external Libraries:** I would prefer not to use any external libraries for this model if possible. Please let me know if any libraries are required.

I'm aiming for a simple design that showcases the parametric capabilities of OpenSCAD. I want to be able to generate different versions of the screwdriver with different sizes, bits, and text labels.

Can you generate the OpenSCAD code for this?

I'm looking to create a customizable vase or pot using OpenSCAD, and I really like the idea of using `linear_extrude` for the main shape. I'd like to have a design where the user can easily adjust the height, radius, and amount of twist, kind of like a spiral. I think it would be cool to also allow the user to adjust the scale of the top compared to the bottom, so that it can be wider at the top or bottom. It should probably be hollow, and the user should be able to optionally specify a hole at the bottom for drainage.

My starting point, though, is a little different, and that's why I need you to make this from scratch.

I want to take a circle, extrude it, and twist it to make a vase. Then, scale the entire vase slightly smaller, move it up a little bit, and extrude *that* shape. This second extrusion should be completely hollow, so that the main shape is the vase, and the scaled down shape is the inside of the vase. Finally, there should be an option to add a hole at the bottom.

Could you please generate an OpenSCAD file with the following parameters exposed to the user?

*   `height`: Total height of the vase.
*   `radius`: Radius of the base of the vase.
*   `twist`: Total twist in degrees applied during the extrusion.
*   `scale`: Scale factor for the top of the vase relative to the bottom.
*   `slices`: Number of slices used for the extrusion; this affects the smoothness of the final shape.
*  `holeRadius`: Radius of the hole at the bottom; set to 0 to disable.
* `innerScale`: a scale to apply to the interior shape of the vase.
* `innerHeight`: This is the height at which to place the extrusion of the interior vase shape. (The final shape of the interior vase will be moved upwards by this variable)

I don't need you to pull in any libraries for this design; I think it can be accomplished with the core OpenSCAD features.

[Assistant]
Vase.scad:
```
Height = 100;
Twist = 360;
Scale = 1.5;
Slices = 10;
Radius = 30;
//Set to 0 if not hole desired
HoleRadius = 3;

difference(){
    translate([0, 0, Height/2]){
        linear_extrude(height = Height, twist = Twist, scale = Scale, center = true, slices = Slices)
            circle(Radius);
    }
    scale([0.85,0.85,0.85]){
        translate([0, 0, Height*.75]){
            linear_extrude(height = Height, twist = Twist, scale = Scale,        center = true, slices = Slices)
                circle(Radius);
        }
    }
    cylinder(100, HoleRadius, HoleRadius, center=true);

Hey, I'm looking to design a customizable comb for 3D printing, and I'd like to use OpenSCAD.  I have some specific parameters in mind, and I'm hoping you can generate the necessary SCAD file(s) for me.

Here's what I'm thinking:

**Overall Structure:**

*   The comb will have a main body, teeth, and optionally a handle.
*   Everything should be created using 2D shapes extruded to a specified thickness.

**Parameters:**

*   **`Thickness`**: The overall thickness of the comb, ranging from 0.4 to 5mm, with steps of 0.1mm.
*   **`BodyHeight`**: The height of the main body of the comb, ranging from 1 to 50mm with steps of 1mm.
*   **`TeethWidth`**: The width of each tooth, ranging from 0.4 to 5mm, with steps of 0.1mm.
*   **`TeethLength`**: The length of each tooth, ranging from 2 to 50mm, with steps of 1mm.
*   **`TeethSpacing`**: The space between teeth, ranging from 0.5 to 30mm, with steps of 0.5mm.
*   **`TeethNumber`**: The total number of teeth, ranging from 1 to 100, with steps of 1.
*   **`HandlePresent`**: A boolean (0 for no, 1 for yes) that determines if a handle is present.
*   **`HandleRounded`**: A boolean (0 for no, 1 for yes) that determines if the handle end is rounded.
*   **`HandleLength`**: The length of the handle (if present), ranging from 2 to 300mm, with steps of 1mm.
*   **`HandleHeight`**: The height of the handle (if present), ranging from 1 to 50mm, with steps of 1mm.

**Specifics:**

*   The teeth should be evenly spaced along the main body.
*   The handle, if present, should be attached to one side of the body.
*   If `HandleRounded` is set to 1, a half-circle should be added to the end of the handle.

I'm thinking a single SCAD file should be sufficient, but if you think a different structure makes more sense, I'm open to suggestions.  I would prefer not to use any libraries for this design - everything should be vanilla OpenSCAD. Let me know what you come up with!

Hey there! I'm looking for some help creating a parametric fan mount for my 3D printer. It's for a Fabrikator Mini, and I've gone through several iterations trying to get it just right, but I'd love an AI's help to do it properly.

The mount needs to attach to the Y-axis stepper motor and hold a 25mm fan. I've found that existing designs don't quite fit the newer V1.5 model, so that's a key issue I'm trying to solve. It needs to be parametric so I can adjust the dimensions for different fan sizes if needed, although right now I'm using a 25mm fan.

Here are some specific things I've been tweaking and would like to control through parameters:

*   **Overall Height:** This will need to be adjustable to accommodate for different motor heights etc.
*   **Fan Hole Diameter:**  The default should be 23mm but it needs to be parameterized so I can use different fan sizes later on.
*   **Fan Screw Distance:** This is currently at 20mm for the 25mm fan, but should be customizable.
*   **Fan Screw Diameter:** Currently using 3mm screws.
*   **Fan Hole Angled:** A boolean parameter to make the hole either angled to direct airflow or not. I think it's helpful to have the fan on a slight angle to the board so that the airflow moves from the stepper toward the electronics board.
*   **Left Arm Inward Angle:** An angle for the left arm to give it a slight inward tilt. I'd like to control this with a parameter. I'm using 4 degrees right now
*   **Right Arm Inward Angle:**  Similar to the left, I may want a small angle on the right arm as well.

There are a few other design considerations based on the printer I'm using. Here's some specific measurements/features that you will want to consider:

*   There's a bracket on the Fabrikator Mini V1.5 that is 10mm high which needs to be taken into account with the design. The design will have to accommodate for this height.
*   The motor itself is 28.3mm wide, 27mm deep and is mostly rectangular.
*   I've also been adding a cutout for a 24.4mm heat sink on the motor.
*   I found a small nub on the Z-axis rod holder that I had to design around on the right side.
*   I am trying to minimize the amount of free space, which helps to keep the bracket rigid.

I think that's the major stuff, hopefully, you can help me design a parametric OpenSCAD design for this. I'd prefer if it didn't rely on any external libraries except for perhaps a standard one like the `MCAD` one for standard sizes and bolts, if needed. I haven't been using any extra libraries for this, but I'd be open to using them if it made sense for this design. Thanks!

Hey, I'm looking to get a parametric OpenSCAD design for a pipe end piece, similar to the Intex-style ones, but a bit more robust around the knob. I've got some dimensions in mind, but I'd like to be able to tweak them easily.

Here's what I'm thinking:

The main body will be a cylindrical shape, hollow in the middle. I want to control the overall `height`, the thickness of the cylinder walls `breadth` and a larger breadth near the base called `breadth_big`. Also, the cylinder has a larger section near the base that is controlled by `height_big`. The inner diameter is important and that is controlled by the `diameter`.

There will be a knob on the side, also cylindrical with a rounded end, that will slide into a corresponding gap. The knob will have a `knob_diameter`, a `knob_roundness` factor, and a `knob_length`. The gap for the knob will be a rectangular cutout, defined by `gap_width` and `gap_height`, with a rounded end. There needs to be two such gaps, mirrored across the center of the part. The rectangular cutout should also have a small rectangular cutout that extends the gap by the width of a smaller half circle.

There should be a sloped transition from the smaller `breadth` to the larger `breadth_big` near the bottom, controlled by a `slope_height` and a `slope_factor`.

I'd like all of these values to be customizable parameters at the top of the file, so I can easily adjust them. Make sure to use the `$fn` variable for smoother cylinder rendering, and also use a `$fn_detail` for more detailed knob rendering.

I'm hoping this part will be strong, especially where the knob attaches. Maybe the ability to increase the `gap_height` easily will help with that.

I'm not sure if it's necessary, but I'd prefer if it used standard OpenSCAD functions and not any external libraries. It'll just be easier for me to understand. Thanks!
