Hi! I'm looking to design a parametric IR pen for a Wii remote, similar to the one described on Johnny Lee's website. I've got a couple of basic scad files here (`wii_3c_pen_02.scad` and `knob.scad`) that have some of the features, but I'd like a more robust and customizable design. I'm envisioning something that's easy to adjust for different battery sizes, knob styles, and overall dimensions.

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

*   **Battery Diameter (batt\_d):** This should control the size of the battery compartment. I'd like to use AAA batteries as a default but be able to switch to others.
*   **Wall Thickness (wall):** The thickness of the pen body material.
*   **Overall Height (height):** The total height of the pen.
*   **Board Thickness (board\_thin):** The thickness of the internal circuit board.
*   **Board Height (board\_height):** The height of the internal circuit board.
*   **Board Width (board\_width):** The width of the internal circuit board
*   **Knob Diameter (knob\_d):** The diameter of the knob.
*   **Knob Offset (knob\_offset):** The distance of the knob from the top of the pen.
*   **Knob Depth (knob\_depth):** How much the knob protrudes into the pen body.
*  **Diode Diameter (diod\_d):** The diameter of the diode hole.
*   **Pit Scale (pit\_scale):**  Controls the scaling of the indentation around the knob.
*   **Twist (twist):** How much the body twists, using linear extrudes
*   **Wing Scale** Controls the size of the fins

The main body should be a twisted shape with cylindrical sections for the battery and a hole for a diode at the top.  I'd like to have a "pit" around the knob. There should also be space for an internal circuit board. The knob itself can be a simple shape with a cylindrical base and a rounded top.  The code should be parametric so I can adjust all these dimensions.

Ideally, I'd like to keep the general structure as in `wii_3c_pen_02.scad` but make it more adaptable. The `knob.scad` file can be used as a starting point for the knob, but it also needs to be parametric.

Would it be possible to generate a set of OpenSCAD files for this, including one for the pen body and one for the knob? I'm not using any particular libraries.

Okay, so I'm trying to design a modular bottle storage system that fits inside a cardboard tube, like the kind used for concrete forms. I want to be able to stack trays inside the tube and then secure them with endcaps and a strap. I'm envisioning something that can hold paint bottles, test tubes, or really anything cylindrical.

Here's the breakdown:

**Core Components:**

*   **Holder Tray:** This is the main tray that holds the bottles. It should be hexagonal with a grid of circular holes to hold the bottles. I'd like to be able to easily control how many bottles fit in the hexagon, specifically how many bottles are along one side of the hexagon. The tray itself needs to have a thickness, and the cylinder parts holding the bottles will need a cylinder wall thickness and a height. There will be a bit of extra space around the outer edges and outer points of the hexagon.
*   **Bottom Plate:** This is a base plate that stacks underneath the holder tray, It will have a similar shape, and could potentially be printed separately. Like the holder, I'll need to be able to set a thickness and a depth for the center and corner posts which the holder sits upon.
*   **Support Plate (Optional):** A thin, flat plate that can be glued between the holder and bottom plate for added rigidity if needed. Like the holder and bottom plate, I'll need to be able to set a thickness for it.
*   **Simple Endcap:** This endcap will fit snugly around the outside of the cardboard tube, and have a groove on the outside for a strap.
*   **Holder Endcap:** An endcap that combines the functionality of the simple endcap with an additional layer for holding bottles. This will need to be similar in design to the simple endcap, but will have an added cylindrical holder and the holes for bottles.
*   **Hex Endcap:** Another style of endcap, this one should be like the simple endcap but is hexagonally shaped.

**Key Parameters:**

I need to be able to control these things via parameters:

*   `plate_thickness`: Thickness of the main plates (holder, bottom, support).
*   `cylinder_wall`: Thickness of the cylinder walls in the holder tray.
*   `bottle_diameter`: Diameter of the bottles I want to hold.
*   `holder_height`: Height of the cylinders in the holder.
*   `bottom_height`: Height of the posts that connect with another tray below.
*   `bottle_spacing`: Gap between the bottles in the tray.
*   `tray_border`:  Distance from the outermost bottles to the edge of the tray.
*   `tube_diameter`: Inner diameter of the cardboard tube I'm using.
*   `tube_wall`: Thickness of the cardboard tube wall.
*   `strap_width`: Width of the strap groove on the endcaps.
*   `corner_rounding`: Controls how rounded the tray edges are within the tube.
*   `bottle_columns`: Number of bottles along one side of the hexagonal pattern, affecting how many bottles are held.
*  `generate_item` - A string parameter that lets me choose which item to generate.

**Design Goals:**

*   **Modular:** The trays need to stack easily and securely.
*   **Parametric:** I want to be able to adjust all the measurements to fit different sized tubes and bottles.
*   **Easy to print:** Designs need to be suitable for printing, and I imagine most of it will be best printed as upside-down shapes.

I'd prefer you generate the files using OpenSCAD. I don't need any external libraries at the moment, but if that would make generating the code easier, I'm open to it.

Does this all make sense?

I'm looking to design a support arm for mounting two filament spools above my Geeetech i3 printer. I've seen a few designs, but I'd like something parametric I can easily adjust. Here's a breakdown of what I'm envisioning:

The basic shape will be a rectangular arm that clamps onto the printer's frame. This arm will then have a round mounting point at the end for the spool holder.

Here are some specifics:

*   **Arm Dimensions:**
    *   I'd like a `Height` variable for the overall height of the arm.
    *   A `Width` variable should control the width of the arm, as viewed when mounted.
    *   The arm needs a clamp, so I need to specify a `Frame_Thickness` variable for how thick my printer's frame is.
    *   I'll need another variable, `Frame_Height`, for the height of the frame I'm clamping to.
    *   Also, how thick the material needs to be around the printer frame should be parametric, so a `Fram_Wall_Thickness` variable should be used.

*   **Mounting Hole:**
    *   There needs to be a circular hole on top for the spool holder, and I need a `Hole_Diameter` variable for that.

*   **Screws:**
    *   I'd like to mount the arm with a screw at the bottom, so I need a `Screw_Clearance` variable for how much space it needs from the bottom of the frame mount.
    *  A `Screw_Gap` variable to specify the clearance around the screw.
    *  And a `Screw_Diameter` to define the size of the screw.
    * I also need a `Thickness` variable which is the `Fram_Wall_Thickness` * 2 plus the `Frame_Thickness`

*   **Clearances:** Please build in a little extra clearance around the frame and screw mounting to ensure it fits properly. It should be a little wider than the frame plus wall thickness.

I think that about covers it. Could you generate the OpenSCAD files for this? I don't have any specific libraries I need you to use.

I'm looking for a parametric cable clamp design that I can 3D print. I need to be able to adjust several dimensions to fit different cable sizes and mounting scenarios.

Specifically, I need to control:

*   **Cable Diameter:** The diameter of the cable the clamp will hold.
*   **Cable Pressing Offset:** An offset that determines how much pressure the clamp exerts on the cable.
*   **Cable Multiplier:** The number of cables to hold side-by-side.
*   **Cable Separator:** A boolean to decide if separators should be used or not between side-by-side cables.
*   **Clamp Width:**  The minimum width of the clamp section that holds the cable(s).
*   **Clamp Height:** The overall height of the clamp.
*   **Screw Hole Diameter:**  The diameter of the mounting screw hole.
*   **Screw Head Diameter:** The diameter of a countersunk screw head to accommodate for.
*    **Screw Head Height:** How deep the countersunk screw should be accommodated in the material.
*   **Width of Screw Part:** The width of the section of the clamp containing the screw hole (and potentially a countersink).
*  **Double-Sided Clamp:** A boolean to decide if the cable holder should be single-sided or double-sided.

The design should also output a grid of clamps using the following parameters:

*   **Print Columns:** The number of clamps to print in a row.
*   **Print Rows:** The number of rows in the grid.
*   **Print Spacing:**  The space between each clamp when printed as a grid.

I would like this to be generated using OpenSCAD. The design should use `hull` to join the basic shapes and make a smooth, printable body. Make sure to add a small tolerance to ensure good fits between different parts of the design.

Hi, I'm looking to create a 360 camera rig for action cameras, like GoPros. I'd like it to be parametric so I can adjust things like the number of cameras, the overall size, and some connector details.

Here's what I'm envisioning:

**Core Structure:**

*   The basic shape should be derived from an intersection of a cube and an octahedron, giving it a sort of chamfered cube look, with the octahedron's vertices extending beyond the cube.
*   I want to control the ratio between the cube size and the octahedron using a `ratio` parameter.
*   The faces of this main shape should have rounded cutouts/holes for mounting the cameras. I need to adjust the roundness and size of these holes with a parameter, `faceR`.
*   There should be a border around the edge of the structure that can be set with a `B` parameter, which should be twice the z-dimension of the GoPro connector.
*   The overall size of the rig should be controlled by a `S` parameter, which is derived from `MaxCamDim` plus `B`, where `MaxCamDim` is the maximum camera dimension.
*   I'd like to have an optional fillet on the edges with a controllable smoothness, set using a `Smoothness` parameter (0 to disable).
*   A `tol` parameter should allow for a small tolerance on the edge connectors, to account for printer variance.

**Camera Mounting:**

*   The rig should support mounting GoPro cameras using standard mounts, and I need a parameter for this: `gopro_connector_z` and `gopro_hole2base`. Assume there's a gopro_mounts_mooncactus library with the `gopro_connector` module.
*   I need to optionally include external GoPro connectors (for accessories) controlled by a boolean `ExtGoPro` parameter and also external 1/4" tripod nuts controlled by a boolean `ExtQIN` parameter.
*   I want to control the number of cameras horizontally, `N`, with a default of 5.

**Orientation:**

*   I want to define the camera's orientation on each edge using a vector/array `orientations`,  which will be 0 for side mounting, 1 for top and -1 for bottom.
*   Also, I want an overall `orient` variable, which can be set to either 0 or 1.

**Other Features:**

*   I would like optional screwdriver holes with a given diameter, set by the `driverHoles` parameter (set to 0 to disable)
*   I want a `model` parameter with options "Full Frame", "Simple Edge", and "Main Edge", where "Full Frame" renders the whole thing, and the other two are single, modular edge pieces

**Modules Needed:**

*   `octahedron(size)`: Creates an octahedron of a given size.
*   `face(s, d, h)`: Creates a rounded cutout face, derived from hulls of cylinders.
*   `faceO(n, S, o)`: Applies rotations and translations to the face module, for different sides.
*   `tripodConnector(d1, h1, d2, h2)`: creates a connector for tripod mounting.
*   `goproConnector2()`: Places the two arm gopro connector with proper translation and rotation for accessories
*   `goproConnector3(z)`: Places the three arm gopro connector with proper translation and rotation, with a modifiable z-axis position.
*   `cornerO()`: Applies rotations and translations to modules placed in a corner.
*   `frame(S, B, ratio)`: Creates the main structure by intersection of a cube and an octahedron, with the face cutouts.
*   `edge(S, B, ratio, extra)`: A reduced version of the frame, with the size parameter.
*   `sedge(S, B, ratio, extra, Smoothness)`: Applies the minkowski to the edges.
*   `edgeConnectors(S, B, o)`: Adds the holes for the cameras and screws in the edges, with proper translation and rotations for different sides.
*   `PosSideA()`: Translate and rotates to the correct position for placing edge modifications.
*   `PosSideB()`: Translate and rotates to the correct position for placing edge modifications.
*   `edge2edgeCon(s)`: Creates the edge to edge connector
*    `SimpleEdgeModifications(o)`: Applies the specific cutouts and edge to edge connectors for the edge.
*   `MainEdgeConnectors(o)`: Creates the connectors and screw holes for the main edge, plus the extra gopro mount.
*  `full()`: Constructs the entire rig by positioning the individual edges.
*   `gopro_torus(r,rnd)`, `gopro_rcyl(r,h, centered, rnd)`, `gopro_profile(th)` and `gopro_connector(version="double", withnut=true, captive_nut_th=0, captive_nut_od=0, captive_rod_id=0, captive_nut_angle=0)`: modules for gopro connectors (from library), that take care of the gopro mount.

**Libraries:**

*   I expect the code to use the `gopro_mounts_mooncactus.scad` for the gopro mount specific details.

I think that covers everything. Let me know if you have any questions!

I'd like to design a parametric PCB slide holder for mounting things like optical end stops or small sensor boards. I have a rough idea of what I'm after, but I need it to be flexible enough to work with different board sizes.

Here's the basic idea: The holder should have a base and two side pieces that grip the PCB. The PCB will slide into the holder from one end. The base should have mounting holes. I want to be able to control the key dimensions of this holder through parameters, including:

*   **PCB Dimensions:**
    *   `pcbWidth`: The width of the PCB.
    *   `pcbLength`: The length of the PCB.
    *   `pcbHeight`: The thickness of the PCB.
    *   `pcbOverhang`: How much the side pieces should overlap the sides of the PCB.
*   **Holder Dimensions:**
    *   `holderLength`: The overall length of the holder.
    *   `holderHeight`: The overall height of the side pieces.
    *   `bottomHeight`: The thickness of the base.
    *  `sideWidth`: the width of the side pieces.
*   **Mounting Holes:**
    *   `holesDiameterBottom`: The diameter of the bottom portion of the mounting holes.
    *   `holesDiameterTop`: The diameter of the top portion (countersink) of the mounting holes.
    *   `holesHeadHeight`: The height of the countersink.
    *   `holesX`: The number of mounting holes in a line.
    *   `holeXStep`: The spacing between the mounting holes.
    *   `holesAngle`: The angle of the line of holes from the x axis.
    * `holesInAngle`: the number of lines of holes

I'd like it so that the mounting holes are a countersunk style and are generated along a line in the base, which could be rotated by `holesAngle` . For easier calibration of optical sensors or similar the holes should be positioned centered on the width of the base. I need to be able to specify multiple rows of mounting holes via `holesInAngle`. The code should be well-commented so I can understand the parameters.

I'd prefer to use the standard OpenSCAD functions, and no external libraries. Could you generate this for me as a single OpenSCAD file?

I'm looking to create an adapter to use SMA-Female antennas on a Yaesu radio, which uses an SMA-Male connector. I've seen a design that does this with a simple sleeve and a subtracted SMA hole, but I'd like a more robust and customizable design.

Here's what I need:

1.  **Core Design:** The adapter needs a cylindrical body, kind of like a sleeve. It should have an outer diameter that can be adjusted, a height that's variable, and a hole in the center that's the size of an SMA-Male connector.

2.  **SMA Connector Hole:** This hole needs to be sized correctly for an SMA-Male connector. I'm thinking that'd be a 6-sided polygon with a radius, and then maybe we'll need a bit of wiggle room. Let's have a parameter for the number of sides on the polygon (maybe defaulted to 6), a parameter for the radius, and a parameter for some extra squish to account for 3D printing tolerances.

3.  **SMA Thread Cavity:** I'd also like the option to include the female thread cavity to accept the male end of the SMA connector. I think that'll need to be an inverse of the SMA male connector in terms of size. Let's add a parameter to control the depth of this cavity, and maybe add a parameter for an additional thread clearance.

4.  **External Threading (Optional):** I want the option to add external threading on the sleeve's exterior to be able to screw it into something. The thread standard I'd like is M14x1, the most common for radio antennas of this size. Let's make this optional with a boolean variable. The height and placement along the cylinder should be controllable. I know this will require a thread library so let's go with the "threadlib" library for that.

5.  **Chamfers:** It would be good if the top and bottom edges of the sleeve could have chamfers. The chamfer should be controlled by a width parameter.

6.  **Parameters:** I want all of these dimensions to be parameters in the OpenSCAD file so I can easily adjust them. Things like the outer diameter of the sleeve, its height, the SMA connector radius, the 'squish' parameter, chamfer width, thread depth, and if we want threads or not. Plus, the number of sides on the SMA connector polygon. I'd also want parameters for where the optional threads begin and end, and any extra clearance for the thread cavity.

7.  **Testing:** I also would like a test module that only renders a small section of the adapter body near the SMA connector hole. This would help me make sure the SMA connector sizing is correct before printing the whole piece.  Let's make that a height parameter as well for how tall this testing piece is.

8.  **File Structure:** It would be great if this was all in a single .scad file.

Basically, I need a highly customizable adapter that is suitable for 3D printing, with the option for SMA threads, and a test module to verify fit. I'm ready to start customizing the parameters myself once I have the base model working.

I need a parametric design for a wire pass-through cover, something that can hide the hole you often need to drill for electrical wires going through a desk or cabinet.

Ideally, it would consist of two threaded rings that screw together from either side of the hole, clamping onto the material. The outer rims should have a lip or flange that covers the edges of the hole nicely. The rings will sandwich the wood, or whatever it's in. Then, a plug would fit into the hole, covering the space in the middle and also acting as a grommet for the wire.

Here are the key parameters:

*   `hole_dia`: The diameter of the hole I've drilled in the material.
*   `hole_depth`: The thickness of the material the cover is being applied to.
*   `lip`: The width of the flange/lip on each ring.
*   `wire_dia`: The diameter of the wire that will pass through the plug.
*   `framewall`: The wall thickness of the threaded rings, including the threads themselves.
*   `wall`: The wall thickness of the flange/lip.
*   `have_lower_frame`: A boolean (1/0) to control whether there is a lower threaded ring or not (sometimes I might only want the upper ring and rely on friction, so it's nice to have the option).
*    `wire_hole_offset`: How far from the center the wire hole in the plug is located.
*   `tol`: A tolerance value to ensure a good fit for threads and plug.
*   `t_pitch`: The pitch of the threads.
*   `t_starts`: The number of thread starts.
*   `lip_cut_left`: An optional cut in the upper lip, for cable routing, on the left side, zero if no cut.
*    `lip_cut_top`: An optional cut in the upper lip, for cable routing, on the top side, zero if no cut.

I'd like the design to use the `metric_thread` module from the provided thread library by Dan Kirshner.  I think the code for the threads might already be included, but if it isn't, then it should be included somehow.

Finally, I need to be able to specify which part to generate from an enum: "frame", "frame_upper", "frame_lower", "plug", or "section". "section" would be the whole thing together.

I think that's everything. Thanks!

[User]
Hi there, I'd like to get an OpenSCAD file (or files, if needed) that can generate a variety of hose connectors. The design I have in mind is based on some existing work, but I'd like a fully parametric version. I need to be able to adjust the following:

1.  **Number of Ports:** I need to be able to specify how many ports I want for each of two different hose sizes (let's call them Size A and Size B). For example, I might want 2 of Size A and 0 of Size B, or 1 of each, or any other combination.

2.  **Hose Sizes:** I need to be able to set the inside diameter (bore) for both Size A and Size B hoses.

3.  **Wall Thickness:** For each hose size, I need to be able to define the wall thickness around the bore. The wall thickness needs to be less than the bore.

4.  **Junction Type:** For multi-port connectors (more than 2 ports), I want to be able to choose between a "T" (square), "Y" (polygon/radial), or "L" (right angle) configuration. The "L" shape will only apply to two port connectors.

5.  **Barb Count:** I need to control how many barbs are on each output port, to accommodate for smaller and larger tubing. This value must be settable for both sizes A and B.

6.  **Inline Connector Shape:** For inline (2-port) connectors, I'd like an option to choose between a round or hexagonal shoulder in the middle.

7. **Hex Size:** If the inline connector shoulder is set to hexagonal, I need a parameter for the size across the flats of the hexagon.

8. **Shoulder:** For round inline connectors, I need a parameter to specify how much the shoulder overhanging the ports.

I think that's all the parameters, but I would like the output to be well structured and readable, and I'd prefer it to be modular if possible to make it easier to read and understand. I'm looking for an entirely new file (or files), not a modification of the one I have. This code will not need to use any libraries.

Hi, I'm looking to get a parametric OpenSCAD model made for a latch spacer. I've got one I made already, and I've attached the code, but I'd really like a fully parametric version that's easier to tweak and extend.

The basic shape is a rectangular block with a rectangular cutout in the middle and two screw holes. I need all of the dimensions to be adjustable through variables. So, I need variables for the overall thickness, the outer rectangle's width and length, the inner cutout's width and length, the screw hole diameter, and the center-to-center distance between the screw holes.

I think the most obvious way to do this would be by using `difference()` with a main rectangular cube, then cutting away a second rectangular cube, and finally subtracting two cylinders for the screw holes. The screw holes should be centered along the central long axis of the part. Could you make sure to keep them evenly spaced around the center of the part?

I'd like it to be clean, simple and easy to understand. I don't need comments in the code, as long as the variable names are clear. I am very comfortable with OpenSCAD, so I don't need any introductory explanations either.

Thanks!

I need an OpenSCAD design for a double pipe clamp, specifically one that sits flat on a surface. I have some specific requirements for flexibility in the design.

Here's what I'm looking for:

1.  **Two Pipe Diameters:** The design needs to clamp two pipes of different diameters. These diameters should be parameters, let's call them `pipe_diameter1` and `pipe_diameter2`.
2.  **Thickness:** The clamp itself should have a consistent thickness, let's call this `clamp_thickness`.
3.  **Clamp Height:** The overall height of the clamp (along the cylinder axis) should be configurable as `clamp_height`.
4.  **Mounting Option:** There should be an optional "pylon" or base that extends from the bottom of the clamp for wall mounting. This should be controlled by a boolean parameter called `use_pylon`.
5.  **Mounting Hole:** I need an optional hole that runs through the center of each pipe clamp to enable screw mounting. This should be controlled by a boolean parameter called `use_mounting_holes`. The diameter of these holes will be `mounting_hole_diameter`.
6.  **Tolerance:** The clamp should have a small gap for tolerance for a secure fit. You can define a default tolerance value, but the whole model should be easily adjusted for the user.
7.  **Clamping Method:** The clamp should be a partial circle around each pipe with a gap removed to allow the pipe to snap in.
8.  **Flat Base:**  The mounting "pylon" should create a flat base for the structure.

The base should be on the opposite side of the pipe holders, forming a flat base, like a "T".

Could you provide the OpenSCAD code? I don't expect any external libraries, just a single .scad file will be great.

Hey, I need an OpenSCAD design for a keyguard for a speech-generating device, specifically something like the GoTalk Now app. I'd like it to be parametric so I can easily adjust it for different device sizes and different grid layouts.

Here's what I'm envisioning:

*   **Basic Shape:** The keyguard should be a flat, rectangular piece that sits on top of the device screen.
*   **Device Size Parameters:** I need to be able to set the width and height of the device screen so the keyguard fits correctly. I'd also like a parameter for the thickness of the keyguard itself.
*   **Grid Layout:** The keyguard will have cutouts arranged in a grid. The number of rows and columns in this grid should be controllable as a single parameter, something like a "field" size. So, for example, a field of 4 would mean a 2x2 grid, a field of 9 would be 3x3, etc., but also fields of 1, 2, should be supported. I'm assuming that for fields 1, 2, and 4 the grid should use 1 row and an appropriate number of columns; otherwise the grid should be a square with an equal number of rows and columns.
*   **Cutout Spacing & Size:** The cutouts themselves should be evenly spaced within each grid cell. Also, the size of the cutouts should be calculated relative to the size of the grid cells themselves, as well as some parameter that controls a spacing value within each cell. I was thinking something like an alpha value that inversely scales the cutout size.
*   **Mounting:** I don't need anything super complicated for mounting, just a simple flat keyguard that sits on the screen.
*   **Library Usage:** I don't want to do everything from scratch, so it would be great if you could use a library like BOSL2 for some of the basic shapes and positioning, if that would be useful. But don't worry about including the library code itself, just make sure the design is using it correctly.
*   **Extra Feature:** Could you include a small lip or edge on one side of the keyguard, just a small rectangle extending from the body on one side that can be used to help orient the user? It should probably be less than 1/5 the screen width, and maybe only extend to around 90% of the height, with a small inset from the bottom of the main body of the keyguard.

Basically, I want a flexible design that I can use for a variety of devices and different grid setups for communication. I think those are the key requirements. Let me know if you have any questions.
