I'm looking to design a car phone mount that can hold a phone in landscape orientation and clip onto a car's vent. I'd like it to be parametric, so I can easily adjust the dimensions for different phone models and cases.

Here's what I'm envisioning:

**Core Structure:**

*   The main body of the mount will be a box, sized to accommodate the phone's width, depth, and height when held in landscape. I need to be able to adjust the inner dimensions and the wall thickness. The wall thickness should be consistent all around.
*   There should be a front cutout, roughly cylindrical, to allow easier access to the phone's screen. The diameter of this cylinder should be adjustable, and the depth of the cut should be controlled with a parameter, too. I'd like to ensure the cylinder is centered relative to the main rectangular body.

**Side Slots:**

*   I need the option for either one or two slots on each side of the phone mount. These slots should be designed to accommodate things like charging cables or buttons. When there are two slots, they should be placed symmetrically, one above and one below the vertical midpoint. When there is only one slot, I'd like to see it placed at a suitable location between the other two.
*   I'd like to control the position of those slots vertically, the radii, and the extrusion depth. The slots should be centered relative to the mount's side wall thickness.
*   I need to be able to choose between a single slot or dual slot config, ideally with a simple variable set to 1 or 2.

**Expansion Slots:**

*   I want to include a series of small slots along the back of the main mount body, as well. They should be roughly cylindrical cutouts on the backside of the mount. I'd like to be able to specify a start/end location on the mount, how many rows and columns of slots to generate, and the size of the cutout. These should be arranged as multiple rows of 3 cutouts with different diameters.

**Vent Clip Attachment:**

*   The mount should have a feature that allows me to attach a vent clip. I would like to control the dimensions of the rectangular base. It should have a cutout area on one of its faces. I want to be able to set its overall position, dimensions and a the cut area using variables. The base and cutout don't need to be fancy or complex; just something simple for the vent clip to attach to.

**Parameters:**

I'd like to have parameters to control:

*   `phone_width`: Width of the phone in landscape (mm)
*   `phone_height`: Height of the phone in landscape (mm)
*   `phone_depth`: Thickness of the phone (mm)
*   `mount_thickness`: Thickness of the mount's walls (mm)
*   `slots`: Number of side slots (1 or 2)
*   `front_cutout_radius`: Radius of the front cylindrical cutout (mm)
*   `front_cutout_depth`: Depth of the front cutout (mm)
*   `slot_radius`: Radius of the side slots (mm)
*   `slot_vertical_offset_1`: Vertical offset of the side slots relative to the vertical center of the mount, should be relative to a single slot
*   `slot_vertical_offset_2`: Vertical offset of the side slots relative to the vertical center of the mount when two slots are desired.
    *   `expansion_start`: Start position of the expansion slots along the width of the mount, a float from 0 to 1
    *   `expansion_end`: End position of the expansion slots along the width of the mount, a float from 0 to 1
    *   `expansion_rows`: Number of rows of expansion slots
    *   `expansion_cols`: Number of columns of expansion slots
    *   `expansion_slot_radius1`: Radius of the smallest slot
    *   `expansion_slot_radius2`: Radius of the middle slot
    *   `expansion_slot_radius3`: Radius of the largest slot
*   `vent_clip_base_width`: Width of the vent clip base (mm)
*   `vent_clip_base_height`: Height of the vent clip base (mm)
*   `vent_clip_base_depth`: Depth of the vent clip base (mm)
*   `vent_clip_base_pos_x`: X Position of the vent clip base.
*   `vent_clip_base_pos_y`: Y Position of the vent clip base
*   `vent_clip_base_pos_z`: Z Position of the vent clip base
*   `vent_clip_cutout_width`: Width of the vent clip base cutout (mm)
*    `vent_clip_cutout_height`: Height of the vent clip base cutout (mm)
*    `vent_clip_cutout_depth`: Depth of the vent clip base cutout (mm)

I think that should cover everything. I don't need any external libraries for this. I'm aiming for a simple, customizable design. Can you generate the necessary OpenSCAD file?

I'm looking to create a corner brace, something like a 90-degree angle bracket, but with customizable holes for both a hex nut and a bolt. I have some basic OpenSCAD code, but I need something more robust, with proper parameters, using a library if possible.

Essentially, I'd like two perpendicular plates joined at a corner, each with a hole for a hex nut and a hole for a bolt, all configurable. I need to be able to change the overall size of the brace (length of each side), the thickness of the plates, the size of the hex nut, the size of the bolt, and maybe even the spacing of the holes from the corner and each other.

Could you generate an OpenSCAD file for this, using the BOSL library, please? I think that would make it easier to handle the hex nut and bolt features correctly. I want to be able to define parameters for:

*   `plate_length`: the length of each side of the brace.
*   `plate_thickness`: the thickness of the material.
*   `nut_size`: the diameter of the hex nut.
*   `bolt_size`: the diameter of the bolt hole.
*  `hole_offset_from_edge`: distance from the edge of the plate to the center of the nut/bolt holes.
* `hole_offset_from_corner`: distance from the corner to the center of the nut/bolt holes.

Also, make sure the bolt hole is a simple cylinder, not a counterbore or countersink. I'd also like the code to be well-commented so I can understand what's going on.  And the default orientation should be the corner at the origin, with the two plates extending along the positive X and Y axes.

I'd like a customizable key ring designed in OpenSCAD. The basic shape is a rounded rectangle, formed by two half-cylinders connected by straight segments, with a clasp mechanism to allow it to open and close.

Here are the parameters I'd like to control:

*   **ring\_diameter:** The diameter of the circular parts of the ring.
*   **ring\_thickness:** The overall thickness of the ring material.
*   **hole\_length:** The total length of the straight portion between the circular parts.
*   **rounded:** The width of the bevel on the outer edges of the ring. I'd like to be able to control this as an actual radius or distance.
*   **overhang:**  This would be the angle of the bevels, specifically used to make sure the bevels are printable, and should be less than 45 degrees.
*   **facets:** The number of sides for the cylinders, so I can control the smoothness of the curves. This is more for visual appeal, rather than functionality.

For the clasp:

*   It should be located in the middle of the straight section of the ring.
*   It should be a simple box with diamond-shaped cutouts, basically a pair of wedges that interlock to prevent accidental opening.
*   The clasp should be integrated so that it isn't a separate part but part of the ring itself.

Please make the design fully parametric. Also, I'd like to use the minkowski() and hull() functions for the ring shape as it can produce nice smooth edges. The diamond bevel should be done with differences and rotations of cubes.

Please let me know if you have any questions.

I'd like to design a parametric tablet holder using OpenSCAD. I've got some specific ideas in mind, and I'd like to be able to customize it for different devices.

Essentially, I need a holder with a rectangular base that acts as a stand. The front of the stand should have a raised lip or frame to securely hold the tablet in place. Think of it like a shallow groove that the tablet sits in. Behind that tablet-holding section, I'd like a box-like area that's open at the top. This box will be used to store things like cables or chargers.

Here's a breakdown of the parameters I'd like to control:

*   **`holder_width`**: The overall width of the holder.
*   **`holder_height`**: The overall height of the holder.
*  **`holder_depth`**: The overall depth of the holder.
*   **`tablet_thickness`**: The thickness of the tablet that the holder is designed for.
*   **`frame_height`**: The height of the lip or frame that holds the tablet.
*   **`storage_box_height`**: The depth of the box area on the back of the holder. This might be the same as `holder_depth` but should be adjustable independantly.

Ideally, the tablet holding area should be positioned at the front of the overall holder, and the storage box should be centered behind it. The lip should be fairly close to the front face of the holder.  I'm imagining the tablet holder sitting upright on a desk, so the base would be the bottom side.

I'd like for the holder to be designed using the basic OpenSCAD primitives (cubes, translates, etc.).

Can you generate the necessary OpenSCAD code for this?

[Assistant]
tabletHolder.scad:
```
holder_width = 100; // [1:500]

holder_height = 300; // [1:500]

holder_depth = 50; // [1:200]

tablet_thickness = 15; // [1:40]

frame_height = 15; // [0:40]

//tablet_width = 205; // [0:500]

difference(){

	cube([holder_width,holder_height,holder_depth],center = true);
	translate([0, holder_height/3, (holder_depth/2)-frame_height+1])
	linear_extrude(height=frame_height)
	square([holder_width+10,tablet_thickness],center=true);

	translate([0,-holder_height/10,holder_depth/5])
	cube([holder_width-5,holder_height*3/4,holder_depth],center = true);
	//translate([(holder_height/8), -(tablet_width/5), (holder_depth/2)-frame_height+1])
	//linear_extrude(height=frame_height)
	//rotate(90) square([tablet_width+10,tablet_thickness],center=true);

	//translate([holder_width/2-3, -(tablet_width/5), 20])
	//	cube([8,tablet_width,frame_height],center = true);

Hi! I'd like to get an OpenSCAD file for a measuring spoon, something I can use for protein powder and the like.

I was thinking a cylindrical cup with a handle. The cup part should be parametric, so I can adjust the volume easily. I'd like to specify the volume in milliliters, and the code should handle the conversion to cubic millimeters. I think I'd prefer to enter it as `volume` rather than something more verbose like `milliliter_volume`. The cup should be a cylinder, and we can calculate the height based on the volume and a fixed radius. Let's set the radius of the cylinder to 8mm, meaning diameter of 16.

The handle should be a simple rectangular prism sticking out of the side of the cylinder. It should start at a height about one mm below the top of the cylinder. Let's say it should be 50mm long, 10mm wide and 3mm thick. It can just be centered on the cylinder when viewed from above. So, 5mm to either side of the cup.

Finally, I'd like the inside of the cylinder to be hollow, creating the cup. This should be done by cutting out a slightly smaller cylinder, maybe with a radius of 8mm, starting a couple of millimeters up the bottom, and going much taller than the height of the cup.

So in summary:

*   Parametric volume of cylindrical cup (in mL), called `volume`.
*   Cylindrical cup, radius 9mm.
*   Handle as a rectangular prism, 50mm x 10mm x 3mm, starting one mm below the cup's top.
*   Hollowed interior using subtraction of cylinder with radius 8mm, starting 2mm above the base.
*   Use a fixed radius of 9mm and a radius of 8mm for the hollowed interior.
*   No need to use any external libraries.

measureingspoon.scad:
```
$fn=150;

volume = 5; // in mililiter

height = (volume * 1000) / (PI * 64);
// h = V / pi * r^2
// 1 mililiter = 1000 cubic milimeters
// -> Volumen * 1000

	union(){
		cylinder(h=height+2,r=9);
		translate([0,-5,height-1])cube([50,10,3]);
	}
	translate([0,0,2])cylinder(h=100,r=8);

I'd like to create a parametric design for a bottle-mug with a handle, suitable for 3D printing. I envision it having a cylindrical base, transitioning to a narrower mouth via a sloped section, and topped with a short cylindrical mouthpiece. The design should include a handle that is attached to the side of the base.

Specifically, I need the following parameters to be easily adjustable:

*   `base_radius`: The radius of the cylindrical base.
*   `base_height`: The height of the cylindrical base.
*   `slant_height`: The height of the sloped section.
*   `mouth_opening_radius`: The radius of the mouth opening.
*   `mouth_piece_height`: The height of the cylindrical mouthpiece.
*   `handle_height`: The height of the handle.

The design should use a boolean difference to create a hollow space inside the bottle-mug. The handle should be formed with a rotation, be attached to the base and be large enough to hold comfortably. I would prefer the handle to be a half circle, although I would like the angle of the rotation to be parametric. Also, I would like the handle to be made out of a swept circle. Please use the `rotate_extrude()` to achieve this.

Please provide the OpenSCAD code for this design and ensure that it's well-commented and easy to understand. This would ideally all be in a single .scad file.

I'd like to design a simple, parametric bench for 3D printing. The bench should have a rectangular top with a cylindrical hole in the center, and four cylindrical legs.

Here's the basic idea:

*   **Bench Top:** A rectangular prism with dimensions that are parameters `bench_x`, `bench_y`, and `bench_z`. There will also be a cylindrical hole going through the top. This hole should have a diameter `hole_diameter` and will go all the way through the bench. It should be centered on the top face.
*   **Legs:** There should be four cylindrical legs. They should each be a specific `leg_diameter` and should have height `leg_height`. They will all start `leg_offset` from each edge of the bench (so their coordinates will be `[leg_offset, leg_offset, -leg_height]`, `[bench_x - leg_offset, leg_offset, -leg_height]`, `[leg_offset, bench_y - leg_offset, -leg_height]`, `[bench_x - leg_offset, bench_y - leg_offset, -leg_height]`.

The whole thing should be parametric and defined in an OpenSCAD file. I'd prefer if the base of the legs was at z=0, so we might need to do a translation. It would also be nice if the object was centered.

I need a parametric grating design for my sink. I'd like to be able to adjust several key parameters, such as the overall height, the thickness of the material, and the spacing of the grating elements.

Specifically, I want a grating that consists of several concentric circles and radial bars. The design should be constructed in layers, with circles at the top, middle, and bottom, and radial bars connecting the circles.

Here's a breakdown of the adjustable parameters I need:

*   **Total Height:** The total height of the grating, excluding the thickness of the base and top circles. This will determine the overall depth of the grating.
*   **Thickness:** The thickness of all the circles and radial bars.
*   **Circles Bottom:** The number of concentric circles at the bottom of the grating.
*  **Circles Top:** The number of concentric circles at the top of the grating
*   **Grating Space:** The space between each concentric circle. This will determine the size of the openings in the grating.
*   **Radians Bottom:** The number of radial bars at the bottom of the grating.
*   **Radians Top:** The number of radial bars at the top of the grating.
*   **Side Grating Number:** The number of radial bars in the middle layer of the grating connecting the bottom and top circles.
*   **Overhang Fix:** A small extra height added to the bottom most elements to make printing easier without supports when inverted (printing the last element first).
*   **Resolution:** A variable to control the smoothness of the circles, implemented by varying the `$fn` value in the cylinder calls.
*  **First Circle**: an integer value, either 1 or greater, where 1 would generate the innermost circle of the grating, and a greater number would start the bottom circle farther from the center.
*  **First Circle Full Height**: a toggle (yes/no) that controls whether the very center of the grating (controlled by the "First Circle" parameter) will have a vertical height or not; a value of "yes" should make this central circle as tall as the other vertical grating, and a value of "no" should have a disk.

I'd like the design to include a function to create radial bars and a function to create concentric circles. The radial bars should be generated using a loop that rotates a cube, and the circles should be generated using a `difference()` operation of two cylinders. Please take into account that printing these gratings upside down can be helpful to avoid supports when using FDM printers.

I'd also like some basic `echo` statements at the beginning that calculate and report:
  * The diameter of the largest circle at the bottom.
  * The diameter of the largest circle at the top.
  * The diameter of the innermost circle.
  * The total height of the assembled grating (including the thickness of base and top circles).

Could you generate the necessary OpenSCAD code for this?  It would be great if this could be a single `.scad` file. I'm not using any libraries, so all the functions should be written from scratch, if that's possible.

Hi, I'm looking to create a customizable shadow mask for UV lithography, specifically for use with negative photoresist in microfabrication. I've got a basic idea of what I want, but I need your help generating the OpenSCAD code.

Essentially, the mask should be a rectangular plate with a grid of cutouts. I need to be able to define the following parameters:

*   **Overall Dimensions:**
    *   Length of the mask
    *   Width of the mask
    *   Thickness of the mask

*   **Cutout Shape:** I'd like to choose from several different shapes for the cutouts. Specifically, I need to be able to select:
    *   Triangle
    *   Square
    *   Pentagon
    *   Hexagon
    *   Circle

*   **Cutout Size:**
    *   The size of the chosen shape. For example, the radius for a circle, the side length for a square, etc.

*   **Grid Arrangement:**
    *   Spacing between the cutouts (center to center)

I need the cutouts to be arranged in a grid pattern, covering most of the mask's surface. The code should subtract the array of the cutouts from the rectangular plate. It also needs to be parametric, so I can adjust all these values through the Customizer. Could you generate the necessary OpenSCAD file(s) to achieve this?

// Enter the length of the shadow mask in mm

// Enter the width of the shadow mask in mm

// Choose the desired shape from the drop down menu:
$fn = 25; //[3: Triangle, 4:Square, 5:Pentagon, 6:Hexagon, 25:Circle]

//Enter the size of the shape
shape_size = 3;

//Enter the spacing between shapes (Center-to-Center in mm)
spacing = 9;

module ShowPegGrid(Size) {
difference(){

//Creates the the general rectangular shape of the shadow mask based on parameters defined above
cube ([length,width,thickness],center = true);

//Based on parameters defiend, a shape is cut out of the rectangle in a 2D array
 for (i=[-length/((spacing+1)*2) : length/((spacing+1)*2)])

Hey, I need a parametric battery tray generator in OpenSCAD. I want to be able to specify the battery type (AA, AAA, AAAA, C, D, or custom) as well as the number of batteries in the tray, and whether I want brackets to hold each individual cell in place.

For the battery types, I want to use these dimensions:

*   AA: 14mm diameter, 50mm length
*   AAA: 10mm diameter, 44mm length
*   AAAA: 8.3mm diameter, 42.5mm length
*   C: 26mm diameter, 50mm length
*   D: 34mm diameter, 61mm length

If I choose "custom," I'd like to be able to define the diameter and length of the battery.

The tray itself should have a base thickness that's also a parameter, and the cell holders should have a similar thickness. The walls of the tray should be flush with the battery edges with some small tolerances so they're easy to print, but I'd like to make the overall external dimensions parametric based on my "thickness" variable.

So, to sum up the parameters, I need:

*   `thickness`: overall wall and base thickness
*   `batteries`: number of batteries
*   `brackets`: boolean, whether to include individual cell brackets
*   `type`: string, either "AA", "AAA", "AAAA", "C", "D", or "custom"
*   `custom_diameter`: custom battery diameter, only used if `type` is "custom"
*  `custom_length`: custom battery length, only used if `type` is "custom"

Could you generate the OpenSCAD code for this? I'm not using any special libraries for this.

if (type == "custom") batteryTray(custom_diameter, custom_length);
else if (type == "AA") batteryTray(14,50);

Okay, I'm looking to design a parametric capo for a guitar, and I'd like to use OpenSCAD. I have some basic dimensions in mind, but I'd like it to be easily adjustable for different neck sizes.

Here's what I'm picturing:

The capo will have a front piece that presses down on the strings, and a curved back piece that fits against the guitar neck. I'd like the front to have a flat face, with cutouts so that it doesn't press directly on the frets. Also, I'd like to have a little cylinder that goes through the front to act as a point of contact on the strings. The front needs to have a thickness so that I can attach an articulation piece.

The articulation piece will connect the front to a curved back piece. I'd like it to have a cylindrical shape, almost like a little pivot point. It needs to be attached to the back with a bit of material that has a small cutout so that it pivots without getting caught. The other end of the articulation piece would be attached to the front piece on the side of the guitar neck.

The back of the capo needs to have an inner curve that fits the guitar neck. It should also have an outer cutout, with a little gap for the articulation piece to connect, and then a sort of half cylinder shape that goes down the neck, so the capo doesn't move. I'm envisioning that this will get scaled to match the curvature of different necks.

Finally, I need a clip mechanism that clamps the front and back pieces together. It should be a hinged structure on one side, and the other side will just push on the back and hold the capo against the strings.

Here are the parameters I have initially:

*   `nut_width`: The width of the guitar neck (e.g., 44mm)
*   `capo_length`: The length of the capo (e.g., 12mm)
*   `capo_back_thickness`: The thickness of the back piece (e.g., 4mm)
*   `capo_front_thickness`: The thickness of the front piece (e.g., 4mm)
*   `neck_shape`:  A scalar to adjust the curvature of the back of the capo (e.g., 0.5)
*   `fretboard_height`: The height of the guitar frets, or how much of the fretboard the articulation piece needs to take up (e.g., 5mm)
*    `articulation_radius`: The radius of the articulation joint (e.g., 2mm)
*   `articulation_offset`: The offset of the articulation piece from the main body (e.g., 2mm)
*   `clip_height`: The height of the clip mechanism (e.g., 7mm)

I'm not attached to these values, but they are a good starting point. I think the best way to implement this would be as one main file that uses the parameters and then does all of the modeling. I am okay with using libraries, so if you think that something like BOSL2 would help implement the clip mechanism or other parts of the design, feel free to use it. I also think that using `difference()` and `union()` will help model the main body. I think that it's really important to make this design fully parametric because I need to print this and it's going to need some tweaking. Let me know if you have any questions.

I'd like to design a customizable cylindrical container with a latticed design and the option to add custom text. I'm thinking something like a pen holder or desk organizer.

Here are the key features I'm looking for:

*   **Overall Shape:** The base shape should be a cylinder.
*   **Dimensions:** I need to be able to specify the radius and height of the cylinder as parameters.
*   **Lattice Structure:** The cylindrical wall should be made up of interconnected rings of "links" rather than a solid wall, forming a sort of lattice or mesh.
*   **Link Design:** The individual links that make up the lattice should be small, thick, and sort of rectangular.
*   **Customization:** The number of links per layer (horizontal ring) should be a parameter.
*   **Layering:** The number of layers should be determined by the overall height and a layer height parameter, so the height of each layer should be a customizable parameter.
*   **Text:** I want the option to add custom text to the outer wall of the cylinder. I should be able to specify this text and a text thickness.
*   **Dependencies:** I'm using the MCAD library, specifically to use the 8bit polyfont for the text.
*   **OpenSCAD Specifics:** The code will need to be compatible with OpenSCAD.

Could you generate the OpenSCAD code for this? I'd like the ability to control all those parameters.

I'm looking for an OpenSCAD design for a parametric L-shaped bracket, specifically for holding PCBs and stencils during solder paste application. I want the design to be adjustable, so I can easily adapt it to different PCB sizes and thicknesses. The brackets should essentially act as a frame, clamping the PCB and stencil.

The key features I need are:

*   **L-Shape:** The bracket should have the basic L-shape, with two arms.
*   **Parametric Dimensions:** I need to be able to specify:
    *   The inner length of each arm (let's call them `inner_length_1` and `inner_length_2`).
    *   The width of each arm (`width_1` and `width_2`).
    *   The overall thickness of the bracket (`thickness`). This should match the PCB thickness.
    *   The radius of the external corners (`corner_radius`).
    *   The radius of a center hole that goes all the way through, for securing the brackets (`center_hole_radius`).
    *   A parameter called `num_parts` to chose between printing a single bracket or a pair.
    *   If printing a pair, a parameter `pieces_separation` for the distance between them.
*   **Rounded Corners:** The external corners of the L-shape should be rounded with the specified radius.
*   **Optional Pair:** I'd like to have the option to print either a single bracket or a pair. When printing a pair they should be oriented as if mirroring the first one, but also with a separation between them.
*   **Simple Design:** The design should be relatively simple and easy to print without needing supports.

I don't have any existing code to start with, so I'm looking for a fresh design. I do not need to make use of any OpenSCAD libraries.

I need an OpenSCAD design for a Raspberry Pi camera mount. The mount should be parametric so I can easily adjust the size of the pegs for the camera mounting holes and also the overall size. I've got a Raspberry Pi and the official color and infrared cameras, and I want to be able to either glue or attach the mount with elastics. I'd like to be able to specify a tolerance parameter to account for printing inaccuracies.

The design should have four pegs that correspond to the camera mounting holes. There should be a supporting structure connecting these pegs, and then arms that extend out with a flat area that would be glued to a flat surface or used for securing with an elastic.

Could you please create an OpenSCAD file that handles these parameters and generates the mount? I am not using any existing libraries and do not need the code to import other files. I need a single OpenSCAD file, not several.

Hi! I'm looking for an OpenSCAD design for a box to hold Carcassonne tiles. I've got a basic idea of what I want, and I'd like to make it customizable with parameters. Here are the details:

*   **Tile Storage:** The box should be designed to hold a specific number of tiles laid flat. I’m targeting 72 tiles, arranged in two rows. This should be adjustable based on the input tile length.
*   **Box Shape:** It’s a rectangular box with a base, walls, and a lid.
*   **Parametric Design:** I'd like to be able to adjust the following parameters:
    *   `tile_length`: The length of a single tile. (This is what I'd measure for my particular tile set.)
    *  `tile_width`: The width of a single tile. This will be a constant.
    *   `tile_height`: The height (thickness) of a single tile.
    *   `num_tiles_per_row`: The number of tiles that will be placed in a single row. The total number of tiles will be twice this value.
    *   `floor_thickness`: The thickness of the box's base.
    *   `wall_thickness`: The thickness of the walls.
    *   `wall_height`: The height of the box walls.
    *   `lid_thickness`: The thickness of the box lid.
    *   `lid_overlap`: The amount the lid overlaps the box walls.
    *  `tab_height`: The height of the tab to keep the lid on the box.

*   **Lid:** The box should have a lid that fits snugly. I'd like there to be a small tab system to keep the lid in place.
*   **Material:** I'm planning to 3D print this, so the design should be suitable for that.
*   **Libraries:** Please use the BOSL2 library, since I like having the extra features there. I don't have any need for other libraries.
*   **Units:** Everything should be in millimeters.

To help visualize this, the current design I’ve been using has dimensions roughly based on a 46mm x 46mm tile, with a two-row setup for 36 tiles each.  I use a 1.3mm wall, 1mm floor and 30mm wall height and a 28mm tab height.  It's not a great design, which is why I want to remake it with all this in mind.

Let me know if you need any other information! I'm excited to see what you come up with!

Hey, I'm looking to create a set of custom rock climbing holds and I'd like to use OpenSCAD for the design. I've seen some cool designs that use random sphere placements to make unique shapes, and I was hoping you could help me generate a parametric model.

Essentially, I'd like to be able to generate holds with the following features:

*   **Overall Size:** I need to be able to set a maximum size (diameter) for the hold.
*   **Difficulty:** I'd like a parameter that changes the thickness of the hold, simulating different difficulty levels. A higher difficulty level should result in less hold material, kind of like a more minimal nub.
*   **Randomness:** I want the shape to be based on a random distribution of spheres, but I need to be able to control the seed so that I can reproduce a specific design if I like it.
*   **Bolt Hole:** The hold needs a central hole for a bolt. The diameter should be adjustable.
*  **Countersink:** The hold also needs a countersunk section for the bolt head. The diameter of the countersink needs to be adjustable, and it should be positioned so the bolt head sits flush.
*   **Number of Spheres:** I should be able to control how many spheres are used for each hold, since that will impact the complexity of the shape.
*   **Sphere Size Variation:** I'd also like to control how much the sphere radii vary from the center to the edge of the hold. Smaller radii at the edges should make more spiky looking holds.
*   **Resolution:** Some form of resolution control for the number of facets would be useful.

I'm planning to use this for 3D printing, and it would be awesome if you could also generate the design for a mold to make them in resin. There should be the option to print the molds directly (as a negative), and also to print a tray, pour in silicone or latex to make a flexible mold, and then remove the flexible mold and use it to make the resin holds. I'm hoping you could design this so that I can select between the holds, molds, and trays.

Also, it should be designed so that I can make an array of holds in the x and y directions. I'm thinking of eventually using this on a home climbing wall I have plans for.

Ideally, the output file should have a way to create a filename suggestion, based on the parameters I have set.

I am not sure which libraries would help with this, but it seems that BOSL2 might be relevant? Also, I have seen some things about using the `hull()` function to combine spheres.

Could you design this for me? Let me know if you have any questions.

/*Instructions:

This program creates an array of rock-climbing holds to be 3D printed. The resulting holds are designed to be secured with a bolt and washer into a (presumably wood) rock-climbing wall. Since the holds need to never move, I imagine they will be secured with an impact-driver and socket-wrench. This requires hex bolts, which can be sharp when falling off of a wall. Therefore the holds are made already-countersunk.

There are 3 types of output: holds, molds, and tray. Holds are designed to be 3D printed at 100% infill. The molds are designed to be 3D printed in silicone (or other flexible material), filled with a resin, cured, and then removed from the mold. The tray is desinged to be printed with low infill of PLA/ABS, poured with a light coating of silicone or latex to make a flexible mold. The mold is then removed from the tray, coated with release agent, filled with resin, cured, and then removed from the tray. The holds will then need to be drilled and counter-sunk to make space for the bolt and socket wrench.

When using this program in OpenSCAD, a suggested filename is provided in the console, which reflects the most important parameters used when creating the STL files. To copy it, highlight the output, right-click, and then select “copy”. Ctrl-C will not work in Windows. Nor can you interact with the console when the “save file” window is up.

Theory:

The “rocks” are made by using the hull() function around n spheres, whose centers are randomly placed inside of a cylinder of Dmax width and  Dmax/4 height. Each sphere is made from a triplet of random numbers between 0 and 1. These numbers are then converted into a triplet of r, theta and z, which define the sphere's position in a cylinder. The radius of the sphere is a Gaussian function of the distance from the center of the sphere. The “a” parameter is related to the width of the Gaussian. Smaller “a” will mean smaller radii of the spheres at the edge, which will result in rocks that have sharper points. Aesthetically, I like a=7. Because the program doesn't “know” if the spheres will poke through the cylinder they were put in, a fudge-factor of mold_thickness_ratio is used. Adjust this higher is you find that some molds have holes in them, adjust lower if your molds are too thick, or to speed up printing.

Once the “rock” is created, the bottom is sliced off to have the rock lie flush on the wall, and then a counter-bore cylinder and bolt hole are “drilled” into the hold so that the holds can be placed without drilling. The "difficulty" changes what percentage of the rock is sliced away. 5.7 slices the rock in half, 5.10 slices a lot away, leaving those annoying little nubs you find on 5.10s, and 5.4 makes orblike easysauce holds that you could climb with 2 limbs.

Hull() has a time of order n*log(n). Where n is the number of points being hull()ed. The number of points in a sphere is proprtional to $fn. Therefore the runtime of a single hold is O($fn*n*log(n*$fn)) and the total runtime is then O(Number_of_units_in_x *Number_of_units_in_y*$fn*n*log(n*$fn)). Therefore it is very important that these numbers not be set too high, or you will crash OpenSCAD.

OpenSCAD has 2 rendering modes, F5=Compile, and F6=Compile and Render. For most things, F5 is faster, for this project, F6 is faster for higher n, $fn. For 3 elements, n=12 and $fn=12 the rendering time on my computer using F5 was about 1 minute. F6 reported 3 seconds to render 3 elements, n=12 and $fn=20. I think because of some differnece in processing the elements inside hull(). As a result, if you are experimenting, and just rapidly want to see different holds (playing with “a” and “seed”), just turn on “testing mode=true” in the “Hold Options” section.

Because OpenSCAD does not have runtime variables, I had to make a long vector with all possible random numbers, and then use the call of "rock_number" to specify a starting position in the vector. The easy way, would be to pass a new random vector to each call of “rock” but you cant do that. The slightly more complicated way would be to be to make a vector of 3*n* Number_of_units_in_x *Number_of_units_in_y random numbers, and then break up the vector into pieces, and then pass those sub-vectors to “rock”. But OpenSCAD can't split vectors either. So I made a big long vector as a global variable, and then in various ways, effectively passed the position in the vector that rock() was supposed to read from. This is hackish bullshit and hard to parse, but it works. Also because of the lack of runtime variables, and the lack of string manipulation, it is impossible to figure out the actual height of a rock. Therefore the position of the counter-bore is just a guess (the 0.5 in hold()) and can be adjusted if you feel adventurous I didn't make a variable for it because I figured it's just easier to change the seed than explain what that parameter is. Also, for the same reason, the center of mass of the rock cant be obtained, and many bores will be off-center.

Alright, I'm looking to create a 3D model that combines a few interesting shapes. It's kind of a weird Christmas ornament, I guess.

Essentially, I need something that looks like two wings attached to a central, bulbous, spirally shape. The wings should be identical but mirrored, and they're going to be mounted opposite each other on the side of the spirally shape. The wings are kind of like rounded, stylized wings, built from a circle and a polygon hull. They will need to be extruded. The spirally shape, I'm calling that a "shit" for now (just a placeholder name). It starts out as kind of a wide, conical base then gradually turns into a sphere. It's actually made from stacked rotated cylinders. And, finally, I'll need an optional cylindrical fixation point that sits on top of the "shit" shape. This fixation point is essentially a cylinder with a rounded head.

Here are the specific things I need to control with parameters:

*   **`wing_thickness`**: The thickness of the extruded wing.
*   **`wing_size`**: Overall size of the wing.
*   **`wing_position`**: How far from the center the wings are positioned.
*   **`shit_size`**: The size/radius of the "shit" shape.
*   **`fixation`**: Boolean, to include or exclude the fixation point.
*   **`fixation_hole`**: Radius of the fixation cylinder and rounding.

The "shit" shape's spiral should be relatively smooth. I'd like it to be built using a `for` loop so that I can control its overall shape through changes in the loop.

I'm expecting that the base of the wings should start along the x-y plane and the top of the `shit` shape should be along z. Also the `fix` should also align with z.

I'd like the whole thing to be built in OpenSCAD, of course, and it should all be in a single file. I don't need to import from any other files or use any libraries. Could you please provide the necessary code?

I need a custom enclosure for a power supply, and I'm hoping you can generate the OpenSCAD code for me. I've got the basic dimensions and placement of components, and I'd like it to be fully parametric so I can tweak things later.

Here's the breakdown:

*   **Overall Box:** The main case should be a rectangular box. I want to define the `Case_Width`, `Case_Height`, and `Case_Depth`. It also needs a `Case_thickness`. The top should be open.
*   **Mounting:** I need a solid bottom and solid side walls, but no top.
*   **Connector:** There needs to be a cutout for a connector, rectangular in shape. I'll need to define `Connector_Width`, `Connector_Height`, and `Connector_Position` (how far up from the bottom the cutout should be). This cutout needs a small offset from the side with a space between the cutout and the walls of the object, and be a hole in the wall.
*   **Connector Screws:** Two small cylindrical holes are needed for screws near the connector cutout. The distance between these holes should be controlled by a `Connector_Screw_Distance`. The screw holes must pierce the wall, from the outside in.
*   **Button:** I'll need another cylindrical cutout on the opposite side of the connector cutout for a button. This should be defined by the `Button_Radius` and its distance from the edge (`Button_Distance`). This cutout needs to be a hole in the wall, from the outside in.
*   **Wire Hole:** I also need a rectangular hole in one of the short sides for wires, defined by `Wire_Hole_Height` and `Wire_Hole_Width`, and some distance in from that short side.

I'd like to avoid using screws if possible, so please make the base solid and the main case walls fit nicely with a good thickness. This case will sit on a flat surface, so there's no need for any mounting on the bottom. I don't want a lid at this time.

I think that covers everything. Can you provide the OpenSCAD file for this? I'd prefer the main box, cutouts, and holes to be separate steps if that makes sense, so it's easier to understand. Also, please don't include any libraries.

Hey, I'm looking to create a custom mount for a filament caliper, primarily to get really accurate measurements for extruder calibration. I'm providing a pretty basic existing SCAD file as an example of the general idea, but I'd like a much more flexible and robust design that's also easier to customize.

Essentially, this mount needs to:

1.  **Attach to an existing extruder:**  I want to be able to define the positions and sizes of mounting holes. The existing file uses two mounting holes, but it might be nice to be able to specify three or even four, and adjust the spacing. I'll need to specify the diameter of these holes, and their distance from the center of the mount. It would also help to adjust the width of the mounting blocks that the holes are embedded in.

2.  **Guide the filament:** I need a clear path for the filament to travel through. The inner diameter of this guide should be adjustable, probably based on the filament diameter. I also need to be able to adjust the length of the filament guide. The existing design has the filament entering from the top and going straight through, I'd like to preserve this orientation.

3.  **Incorporate the caliper:** The design needs a slot for a digital caliper. Crucially, the distance of the "measuring" section from the filament entry point will need to be adjustable so I can accurately record the filament movement in the caliper. The slot needs to allow enough of the caliper's jaws to extend for effective measurements. I also need to specify the thickness of the caliper's jaws and have the mount accommodate them and provide a place for the bottom jaw. I also need to be able to adjust the length of the main slot as well as the "rest" after the measurement area that is present in the example file.

4. **Bowden Tube Coupler:** I need to include a hole to attach a bowden tube coupler, the diameter should be adjustable and the length should also be adjustable.

5.  **Be Parametric:**  I want to be able to easily adjust *all* of these dimensions, and ideally have clear names for each parameter. The existing SCAD is okay but it doesn't provide enough customization for my needs and is not very clean or easy to understand.

I'm not very experienced with OpenSCAD, so a well-commented and easy-to-understand design would be awesome. Ideally, the code should use libraries when appropriate, but I don't really know which ones would be best here. If you could generate multiple scad files, maybe with different mounting options, that would be great as well!

Thanks in advance for the help!

Hi, I'm looking to design a frame and wheels for a small maze-solving robot, and I need some help generating the OpenSCAD files for it. I've got some specific requirements and parameters that I need to be adjustable, so I'd like the design to be fully parametric. I'd prefer to keep the frame and wheel in separate files.

First, for the frame, I need to be able to choose between a few different servo motors. Specifically, the "SM-S4303R" and a "Parallax" servo. The dimensions of the frame and screw holes will need to adjust depending on which one is selected. Similarly, I also need to be able to specify which mouse sensor board is being used. I need support for "Logo Mouse v4+", "Logo Mouse v1 - v3", and "Nano Mouse / espMouse" options. The marker cutout for the mouse board should change depending on this choice. There's also a parameter for the angle of the side sensors called 'sensorAngle', which should default to 10 degrees.

The overall frame design should be a symmetrical shape, with mounting points for the servo motors, a breadboard, and sensors. I need screw holes for mounting the servos, cutouts for the servo wires, and a small cutout to access the potentiometer on the SM-S4303R servo if that option is chosen. There should also be sensor slots and divots to help with sensor installation, along with cutouts for the mouse marker. The frame design also includes a section where a battery and castor ball would be mounted. PCB mounting holes should be included based on the selected mouse sensor board.

For the wheels, I need to specify the diameter of the servo post, the number of spokes, and the inner and outer diameters. I also need a parameter for an O-ring that fits between the two diameters, and a small screw hole to attach the wheel to the servo post. The design should have a cylindrical hub and a section that protrudes for the o-ring to sit into.

I would like to use color to help visualize the different sections of the model, but this isn't a hard requirement. I'd also like to use a fillet to smooth out the edges on the wheel design.

I'm not using any existing libraries, so please don't assume I have any preinstalled.

I'm looking to create a customizable case for a phone, similar in concept to a DODOcase. I have a basic idea in mind, but I'd like it to be parametric so I can easily adapt it for different phone models.

Specifically, I need a design that consists of a frame. The frame should have an outer shell and a recessed area to hold the phone itself. I'd like to define parameters like:

*   `phone_height`
*   `phone_width`
*   `phone_depth`
*   `frame_thickness`: The overall thickness of the frame material.
*   `side_rail_width`: The width of the left and right side rails of the frame.
*  `frame_padding`: the additional space around the phone for a snug fit.

I'd like the frame to be generated with the outer dimensions calculated from `phone_width` and `phone_height`, plus the padding on all sides. The recessed area where the phone goes should have the precise dimensions of the phone, as defined by the parameters. The frame should have side rails on the left and right.

Could you generate an OpenSCAD file (or files) using these parameters? I'd prefer to keep it simple for now, without any fancy curves or cutouts. The primary goal is a functional parametric design that I can build upon. I want to specify all dimensions in millimeters. Please do not use any external libraries.

dodocase.scad:
```
//Size of phone, default iphone 4
height = 58.6;
width = 115.2;

depth = 1*20;//9.3;
//iPhone 4 : 115.2 mm (4.54 in) H; 58.6 mm (2.31 in) W; 9.3 mm (0.37 in) D
//iPhone 5 : 123.8 mm (4.87 in) H; 58.6 mm (2.31 in) W; 7.6 mm (0.30 in) D

module dodocase()
{
	difference() {
		//outer frame
		union()	{	translate([-140/2,-75/2,-8/2]) cube([140,75,8]);
			translate([-140/2,-75/2,8/2]) cube([3,75,5]); //side left
			translate([140/2-3,-75/2,8/2]) cube([3,75,5]); //site right
		}
		//phone
		{
			translate([-width/2,-height/2,-depth/2]) cube([width,height,depth]);
		}
	}
}

dodocase();
