I'm looking to design a set of Cessna-style engine controls for a home cockpit simulator, and I'd like to have the OpenSCAD code to generate all the parts. I've got some existing .scad files and stl files that describe the overall design, but I need a more parametric solution that can be easily adapted to changes in component dimensions. I'm including those for reference.

Here's what I'm trying to accomplish:
I need three control assemblies: carburetor heat, throttle, and mixture. Each will have a knob, a rod that attaches to the knob, a coupler that attaches to a potentiometer, a potentiometer holder box, a panel guide with a nut, and obviously the panel itself, which will be an arbitrary thickness (I will define that elsewhere). I'll be using linear slide potentiometers, and I'd like to make sure the design allows for easy replacement.

The knobs themselves already exist as STLs. For the carb heat knob, there's `carb_heat_knob_orig.stl`. I don't need you to generate code for the knobs, though I'd like you to include parameters for the rod hole diameter.

The rods will be metal rods, and I would like to parameterize the diameter of the rods.  I need to design the rod couplers to adapt the rods to the potentiometer levers.  The coupler should have a base that attaches to the potentiometer lever with two set screws to keep it from rotating, as well as a hole for the rod.  I want this hole to be a friction fit, with an adjustable friction fit parameter. I also want the rod to be secured by electrical tape rather than set screws because it reduces the risk of the rod becoming detached on rotation. I have provided the reference coupling.scad, which can be used as a guide, but I want to create something that is completely parametric.

The potentiometer holders should be a simple box with mounting holes for the potentiometers.  They should be designed in such a way that the potentiometer can be easily inserted into the box after printing and should have a way to screw them to the panel using the panel guides (see below).  The dimensions of the potentiometers are listed in the description as "linear slide potentiometers".

The panel guides will secure the rods to the panel.  They should have a threaded end that screws onto the box. I'd like the guides to also have a nut.

Here are some initial parameters I'd like to use:
- `RodDiameters`: A vector of the diameters of the rods I might use (e.g., `[3.17, 4.76, 6.35]` which are 1/8 in, 3/16 in, and 1/4 in respectively)
- `FrictionAllowance`: The amount of extra space to add to the rod hole for a friction fit (e.g. 0.4mm)
- `PotentiometerLeverHoleWidth`: Width of the hole on the potentiometer lever.
- `PotentiometerLeverHoleHeight`: Height of the hole on the potentiometer lever.
- `PotentiometerMountHoleSpacing`: Spacing between mounting holes on the potentiometer.
- `PotentiometerMountHoleDiameter`: Diameter of mounting holes on the potentiometer.
- `PotentiometerBoxThickness`: Thickness of the potentiometer box walls.
- `RodGuideScrewThreadDiameter`: Diameter of threads on the rod guide.
- `RodGuideScrewThreadPitch`: Pitch of threads on the rod guide.
- `RodGuideOuterDiameter`: Diameter of the exterior of the rod guide.
- `RodGuideHoleDiameter`: Diameter of the rod guide hole.
- `PanelThickness`: Thickness of the panel that everything is mounted on
- `KnobRodHoleDiameter`: Diameter of the rod hole in the knob

I'd like to use the `MCAD` library to handle the threads.

Could you generate the necessary OpenSCAD files based on these requirements? I'm hoping that this will be completely parametric so I can change these values easily later on. Thanks!

Hey, I need an OpenSCAD design for a parametric fan mount. I've got a few different sized fans I need to mount, and I'd like the design to be adaptable.

Here are the key parameters I want to control:

*   `fan_width_height`: The width and height of the fan. I need this to be one of the following sizes: 40, 50, 60, 70, 80, 92, 120, 140, 200, or 220 (all in mm).
*   `fan_depth`: The depth of the fan (in mm).
*   `fan_screw_diameter`: The diameter of the screws used to mount the fan.
*   `bottom_plate_z`: The thickness of the mount's base plate.
*   `bottom_screw_diameter`: The diameter of the screws used to attach the mount to whatever I'm mounting it to.

The mount should have a base plate and a frame to hold the fan. I'd like the base plate to extend back a bit, with a portion of it going under the fan. There should be a stabilization bar at the back of the frame that wraps around to meet the top. The fan mount frame should have a cutout for the fan, as well as a cutout at the top. The fan screws should attach at the appropriate spacing according to common fan sizes, and there should be two screw holes on the base for attaching the mount - one offset to the side and one in the center.

I'd like all the dimensions to be in millimeters. Please make sure it works for all the specified sizes in `fan_width_height`. I also want the design to be mirrored down the center, so I only have to define half of the object. I don't need any external libraries used for this - just the basic OpenSCAD functions.

Could you generate the OpenSCAD code for me, including comments to make it readable?

// Depth of your fan in mm (depending on your printer it might be better to add 1mm).
fan_depth = 16;

// Diameter of the screws of your fan in mm.
fan_screw_diameter = 4;

// Thickness of the mount plate in mm.
bottom_plate_z = 4;

// Diameter of the scews used to attach this item in mm.

I'm looking to design a tiered shelf system for my pantry. It needs to be parametric so I can adjust it to fit different spaces. I have some specific requirements in mind, and I think it can be made modular.

The overall design is a series of platforms, stacked vertically, to create a tiered effect, allowing for better visibility of items placed further back on the shelf. I'd like the following parameters to control the overall shape:

*   `shelf_count`: the number of tiers/platforms.
*   `shelf_width`: the overall width of the shelf unit
*   `shelf_depth`: the depth of each individual platform (how far back it goes). I'd like each platform to have the same depth, not cumulative.
*   `step_height`: the vertical distance/height between each platform.
*   `wall_thickness`: the thickness of the material used for the platforms and supports, if any.
*   `style`: a selection between a solid platform, a framed platform, and a bridged platform. A solid platform will have a full surface; a framed platform would have a border along the front and sides, and a bridged platform would only have a thin support across the front and sides.

I'd like the design to be such that the whole shelf unit is centered at (0,0,0). The platforms should stack directly on top of each other. If the selected style is "framed" or "bridged", then I'd like there to be supporting risers at the front of each tier to support the next tier, with the option of a support also at the back of the bottom tier if "bridged" is chosen.

I'm not sure how best to implement the different styles using OpenSCAD, but I imagine using conditional statements to either add or not add certain parts.

Could you generate an OpenSCAD file (or files) that achieves this? I'm not using any particular library, so no need to worry about that.

Hey, I'm looking to design a parametric set of plant trays and basins for growing cat grass, and I'd like to use OpenSCAD. I want the design to be flexible so I can adjust things like the size, wall thickness, etc. I've already done some prototyping and have a general idea of what I need, but I'd appreciate it if you could create the OpenSCAD code from scratch.

Specifically, I need two modules: one for the seed tray itself and another for a basin that fits underneath to catch water.

Here are the key features and parameters I'd like to control:

**General Parameters (for both tray and basin):**

*   `outer_diameter`:  The overall diameter of the tray/basin.
*   `height`: The overall height of the tray/basin.
*   `wall_thickness`: The thickness of the walls.
*   `bottom_thickness`: The thickness of the bottom.

**Seed Tray Specific Parameters:**

*   `hole_diameter`: The diameter of the drainage holes.
*   `hole_spacing`: The distance between drainage holes.
*   `outer_margin`: The width of the solid area (without holes) between the wall and the first row of holes.

**Basin Specific Parameters:**

*   The basin should be slightly larger than the tray so it nests nicely, but without needing explicit parameters for sizing. The inner diameter should be a little more than the outer diameter of the seed tray.
*   The basin should have some sort of ribs on the outside for easy grip and to give it some structural support. Maybe have 6 ribs equally spaced?

I'd like the code to be organized into two modules, `seedTray()` and `basin()`. I'd like to use a flag called `basin` that, if set to 1, will output only the basin and, if set to 0, will output only the tray.  It might be helpful to declare the key parameters at the beginning of the file.

I don't need any specific libraries beyond the core OpenSCAD functionality, just something parametric and reasonably robust that I can tweak. Let me know if you need more details.

[Assistant]
seed_tray.scad:
```
// basin/tray (basin=1, tray=0)
basin=0;                // set to 0 for seed tray, 1 for basin
//Outer Diameter
outer_diameter=84;
// Height
height=15;
// Wall Thickness
wall_thickness=0.6;
// Bottom Thickness
bottom_thickness=1;
// Hole Diameter
hole_diameter=2;
// Hole Spacing
hole_spacing=0.5;
// Outer Margin (width of area by wall with no holes)
outer_margin=2;

module seedTray() {
    difference() {
        cylinder(d=outer_diameter,h=height,$fn=90);
        translate([0,0,bottom_thickness]) cylinder(d=outer_diameter-wall_thickness*2,h=height,$fn=90);
        count = floor((outer_diameter/2-wall_thickness-outer_margin-hole_diameter/2) / (hole_diameter+hole_spacing));
        for(r=[0:(outer_diameter/2-wall_thickness-outer_margin-hole_diameter/2)/count:outer_diameter/2-wall_thickness-outer_margin-hole_diameter/2+0.1]) {
            inc = 360 / floor((2 * PI * r) / (hole_diameter+hole_spacing));
            for(a=[0:inc:359]) rotate([0,0,a]) translate([0,r,-1]) cylinder(d=hole_diameter,h=22,$fn=16);
        }
    }
}

module basin() {
    difference() {
        cylinder(d=outer_diameter+2+wall_thickness*2,h=height,$fn=90);
        translate([0,0,bottom_thickness]) cylinder(d=outer_diameter+2,h=height,$fn=90);
    }
    for(a=[0:60:359]) rotate([0,0,a]) translate([outer_diameter/2+1-outer_diameter/20,-1,0]) cube([outer_diameter/20,2,height/2]);
}

if (basin)
    basin();
else
    seedTray();

I need a parametric foosball holder designed in OpenSCAD. I've got a few specific requirements, and I want to be able to adjust the design easily through parameters.

First, the foosballs I'm using are 37mm in diameter, but I'd like to make that a parameter so I can change it later. Also, I want to stack a variable number of foosballs vertically, starting with two. I'll also need to specify the number of columns of foosballs, initially I'm thinking 8 columns, but I need this to be adjustable as well.

Next, I'd like the option to use either a single column or a double column layout, where in a double column layout, the number of columns would refer to the number of *pairs* of columns. I also need to have an option to allow picking the balls out from the bottom.

I want to consider side cutouts, but whether to actually use them should be a parameter, too. One side cut-out parameter should only enable the side cuts if the model will still be stable and another one that allows for side cuts even if they might destabilize the model if the user wants the look.

The frame width (the material around each ball and column) should be adjustable too; let's start with 2mm. The ground plate height should also be adjustable, starting at 5mm.

Finally, for smoother curves, I want to be able to control the number of fragments used for circles, etc. via the `$fn` variable, defaulting to 128. I also would like to be able to turn on more intensive rendering for previews, but have that default off since it's time-consuming.

The final model should have rounded edges for a nicer look. There should be bevels on the vertical edges of the holder itself, and also bevels on the edges of the ground plate. The model should be designed in a way that all these beveling functions can be applied in combination.

Basically, I need a fully parametric foosball holder, with options for single/double columns, bottom removal, side cutouts with different use-cases and rounded edges. I'd like this to be a single OpenSCAD file, with no external libraries needed. Can you generate that for me?

I'd like a design for a lathe faceplate that I can 3D print. It needs to be parametric so I can adjust the dimensions for different projects. I have a bolt I plan to use, so I need to be able to specify its diameter and head size as well.

Here are the basic parameters I'm thinking of:

*   **Overall Diameter:**  The main diameter of the faceplate.
*   **Plate Thickness:** How thick the main part of the faceplate is.
*   **Stem Length:** The length of the stem extending from the back of the faceplate, which will interface with the lathe.
*   **Stem Top Thickness:** The diameter of the stem at the top, where it attaches to the plate.
*   **Bolt Diameter:** The diameter of the bolt that will pass through the center.
*   **Bolt Head Size:** The size of the bolt head that will fit into the counterbore.
*   **Bolt Head Hole Depth:** The depth of the counterbore for the bolt head.
*   **Screw Diameter:** The diameter of the screws used to attach material to the faceplate.

I'd also like to have four screw holes spaced evenly around the faceplate, and I'd like the screw holes to include countersinks. I need a fillet where the stem meets the faceplate for added strength.

I think it would be great if you could also include a center finder that would fit over the bolt head.

Please generate this design in OpenSCAD. I'm not using any external libraries, so everything will need to be in a single .scad file. I have some existing code that I can share, but I'd prefer if you started from scratch to give me a clean design. Thanks!

Okay, I'd like to design a customizable container and lid using OpenSCAD. It needs to be parametric, so I can adjust the dimensions. I'm thinking something similar to what I saw on Thingiverse, specifically "Customizable Container with Knurled Lid" (thing:612709) but with the added ability to adjust the lid's height independently from the container and with a modified grip ring. I'd also like to incorporate the "Knurled Surface Library v2" from (thing:32122). I've attached a modified version of this design, but I would prefer to start from scratch to avoid any potential issues. Here are the specifications:

**Overall Design:**

*   **Container and Lid:** The design should consist of two parts: a container base and a screw-on lid.
*   **Parametric Design:**  All key dimensions should be easily adjustable through variables.
*   **Knurled Grip Ring:** Include a customizable knurled grip ring on both the base and the lid.

**Dimensions:**

*   `diameter`:  Inner diameter of the container (minimum 8mm). The outer diameter will be calculated based on the wall thickness.
*   `height`: Inner height of the container. Again, the outer height will be calculated based on the wall thickness and bottom/lid thicknesses.
*   `outside_chamfer`:  Chamfer percentage on the *outside* bottom edge (0 for flat). Default should be 2% of the diameter.
*   `inside_chamfer`: Chamfer percentage on the *inside* bottom edge (0 for flat). Default should be 0.5% of the diameter.

**Thickness:**

*   `wall_thickness`: Wall thickness of the container and lid. A default value of -1 should result in 2mm thickness for diameters up to 60mm, 2.5mm up to 100, and 3mm for larger diameters. Otherwise, respect whatever value the user inputs, but ensure the value is at least 1.0mm.
*   `container_bottom_thick`: Thickness of the container bottom. If set to -1, it should use the wall thickness. Users should be able to set their own value.
*    `lid_top_thick`: Thickness of the lid top. If set to -1, it should use the wall thickness. Users should be able to set their own value.

**Expert Settings:**

*   `part`: A variable to choose if you want only the container, only the lid, or both. Use `container_` for container, `lidCon_` for height adjustable lid, and `both` for both container and lid.
*    `backlash`: The space between the lid and container threads. A default of -1 should equal 1/4th of the `wall_thickness`, but users can also set a specific backlash. Should always be at least 0.2mm.
*   `quality`:  A variable to adjust the `$fn` for quality control. Options like 80 (good), 100 (high), 120 (very high), and 150 (best) would be helpful.

**Knurled Ring Settings:**

*   `ring_bottom`: A boolean (1 for yes, 0 for no) to add a grip ring to the container base. Defaults to 1.
*   `ring_top`: A boolean (1 for yes, 0 for no) to add a grip ring to the container lid. Defaults to 1.
*  `ring_thickness`: The thickness of the grip rings. Maximum value of 5/6 of the height of the container. Default is 20.

**Additional Notes:**

*   There needs to be a thread for the lid and container to screw together. The thread should use a trapezoidal shape and have a height that depends on the diameter. Thread height should be diameter/6 for diameters > 20, and 20/6 for smaller diameters.
*   The lid should have an internal lip that fits inside the container.
*   Ensure that all calculations for offsets and positions correctly consider `wall_thickness`, `container_bottom_thick` and `lid_top_thick`.

**Libraries:**

I think you'll need the functions from "Knurled Surface Library v2", so please include those.

I think this covers everything. I'm looking forward to seeing the design!

Hey, I'm looking to create some custom inserts for my HDX parts organizer. I've got the one with the different-sized compartments. I'd like to use OpenSCAD to generate these, and I want to make it parametric so I can easily adjust the number of compartments and the dimensions.

Here's the breakdown of what I need:

*   **Overall Structure:** I need to create rectangular inserts that fit into specific slots in the HDX organizer. The design should handle multiple inserts stacked vertically. I'll specify how many layers high I want the insert to be.
*   **Slot Sizes:** The HDX organizer has different-sized slots (as shown in the provided diagram). I need to be able to specify which slot the insert is being designed for (slots 1-4). Each slot has specific inner dimensions.
*   **Compartments:** Inside the main insert, I want to be able to divide it into smaller compartments using walls. I need to specify how many compartments in the X and Y direction. The height of each compartment should be the total height divided by the amount of vertical layers.
*   **Wall Thickness:**  I need to be able to adjust the wall thickness of the dividers and the outer walls of the insert.
*   **Chamfer:** I want to be able to chamfer both the outer and inner edges, with separate radius controls.
*   **Lid Cutouts:** The insert that will be closest to the lid needs to have small cutouts on the top edge for the lid to close. I want a flag to control when these are included. The cutouts should be located near each corner of the insert and also in the middle of the long sides for slot 3 only.
*   **Labels:** I need a way to label the parts with a text label on the side of each bin. The text should be automatically generated based on the dimensions of the final shape.
*   **Libraries:** I'm fine with using common libraries like BOSL2 if it helps with the chamfers or other features. I am using OpenSCAD 2021.01 if that helps with compatibility.

Essentially, I want a script that allows me to input the slot number, whether it's a top layer, the number of compartments in X, Y, and Z, wall thickness, chamfer radiuses, and have it generate the correct insert with internal divisions and lid cutouts if needed, with a text label. The number of vertical layers (compartmentsZ) refers to the amount of inserts stacked into a single slot.

Could you please create a parametric OpenSCAD file or files for me?

Hey, I'm looking to create a customizable box with a ventilated cover, specifically for mounting a power supply in a wall.  I need to be able to adjust the dimensions of the box, the ventilation holes, and some other features.

Here are the specific things I need to control, along with some initial values as examples:

**Box Dimensions:**
*   **Inside Width:** (e.g., 60 mm)
*   **Inside Length:** (e.g., 170 mm)
*   **Inside Depth:** (e.g., 60 mm)
*   **Wall Thickness:** (e.g., 2.4 mm)
*   **Inner Diameter of Screw Mounts:** (e.g., 4.8 mm) -  This is for the internal screw mount.
*  **Outer Diameter of Screw Mounts:** (e.g., 10 mm) - This is the outer diameter of the ring around the screw mount.

**Cover Parameters:**
*   **Cover Overhang:** (e.g., 5 mm) - How much larger the cover is than the box's footprint
*   **Screw Hole Diameter:** (e.g., 4.5 mm) - For the cover screw holes
*   **Ventilation Hole Width:** (e.g., 15 mm)
*   **Ventilation Hole Height:** (e.g., 3 mm)
*   **Ventilation Hole Spacing:** (e.g., 5 mm)
*   **Perforation Height:** (e.g., 35 mm) - This might be better described as the x-axis limit of the ventilation holes, I think. Also, maybe this should be named `perforation_width` instead?
*  **Cover Depth:** (e.g., 1.5 mm)

**Additional Notes:**

* The screw holes on both the box and cover need to align.
*   I plan to use M4 x 10mm screws and M4 brass inserts.
*   I'd like the option to generate just the box, just the cover, or both parts together.
* For some of the dimensions, I was planning to do calculations based on other input parameters, so keep that in mind.
* I'm okay with using the default circle quality settings, if that helps keep things simpler, but I would like to be able to customize the circle quality if I chose.

Can you create a parametric OpenSCAD design based on these specifications? I think that should cover the basics of what I'm aiming for.

I'm looking to create a set of customizable storage boxes, inspired by the "Assortment system box 1x1" design by chappel but with some key modifications and the ability to create larger sizes by combining units. I’ve already got a working version in my head, but it's a bit messy and I need a clean, parametric design, so I'm hoping you can help me generate the OpenSCAD files.

Here are the key features and parameters I need:

*   **Unit Dimensions:** The basic building block is a box, and I need to be able to define its width (`unit_x`), depth (`unit_y`), and height (`unit_z`). The default values should be around 55.6, 54, and 75mm respectively, to match the original design, but I need to be able to change these values, and have everything else adjust accordingly.
*   **Multiple Units:** I need to be able to create boxes that are multiples of the base unit in the x and y directions. So, I need parameters for `multiple_x` and `multiple_y`. For example a 2x3 box is 2 units wide and 3 units deep.
*   **Draft Angle:** The sides of the box should have a draft angle to make it easier to remove from a mold (if needed) and for stacking. This will be specified by a `draft` angle parameter, with 90 degrees being vertical. The default needs to be 87 degrees.
*   **Corner Rounding:** I'd like rounded corners, controlled by a `radius` parameter, default radius is 3.
*   **Top Lip:** There needs to be a lip at the top of the box with a variable height, which I'll call `top_lip`, default height should be 7. This will also have rounded corners.
*   **Label Ledge:** There should be a small ledge on one of the sides for attaching a label. This should have its own size parameters, `ledge_x`, `ledge_y`, `ledge_z` and a bit of a drafted edge.
*   **Wall Thickness:** I need to control the wall thickness of the box using a `wall` parameter. I'd like to change this value depending on if the base box is a single unit or wider.

So, in summary:
  *   I'd like an overall `box` module that accepts the multiples `multiple_x` and `multiple_y`.
  *   I need these primary parameters to control the box's size and shape: `unit_x`, `unit_y`, `unit_z`, `draft`, `radius`, `top_lip`, `ledge_x`, `ledge_y`, `ledge_z` and `wall`
  *   The design should create a box with the specified shape, rounded edges, draft, lip, and label ledge.
  *   I’m looking for a modular design that would allow for different combinations of multiple unit sizes
  *   I’ll also need a module called `round_plate_type1a` to create plates with rounded edges that I can use to create some of the rounded shapes (this will need parameters of `size_x`, `size_y`, `size_z`, and `r`, and creates the shape in the X direction). `round_plate_type2a` that creates a shape with rounded corners (also with parameters of `size_x`, `size_y`, `size_z`, and `r`, as well as a color parameter `col`) and one called `round_plate_type3_center` to create rounded corner cubes that can be used for the bottom corner rounding (with parameters `size_x`, `size_y`, `size_z` and `r`). And some modules called `round_plate_type1y` and `round_plate_type2a` that call these, but rotated as needed.
  *  I won't need any external libraries, just the core OpenSCAD functionality.

Essentially I'm looking for a set of .scad files that would let me generate a single box of any size based on multiples of the unit sizes. It would be great if the code was clean and well organized with comments. Thanks in advance!

[User]
I'd like to design a customizable container, like a jar or a vase, with a rippled or segmented look on its sides. I want to be able to control the overall height, the diameter at the bottom, and the diameter at the top. I also want to control how many radial segments there are, kind of like the sides of a polygon, but it should be a smooth curve between the edges, not a hard edge. The vertical segments or "ripples" should also be adjustable. Finally, I need to be able to specify the wall thickness of the container.

It would be really great if the resulting container had the rippled segments alternating in and out, so that the outer layer is not smooth, but bumpy. I think that the best way to do this would be to generate rings of a constant height and alternating inward and outward. The bottom of the container should be a flat disk.

Could you create the necessary OpenSCAD files for this? I don't need any particular library, I'd just like it to work with base OpenSCAD. I need a file to define the design and a file to set the parameters, or you can include it all in one file, if that makes more sense.

// vertical segments count
