I need a parametric OpenSCAD design for a honeycomb wall rack. I want to be able to customize several key aspects of it.

First, the basic structure needs to be a grid of hexagonal cells. I need to be able to specify the number of rows and columns. I'd also like to control the minimum diameter of each hexagon's opening and the height of the cells. There should be a defined wall thickness around each cell. Finally, the cells should be tilted forward at a specified angle.

Second, I need the ability to add mounting plates at specific cell locations.  I'll need to specify these locations using a row and column coordinate system. Each mounting plate should have a screw hole of a given diameter, offset a specific distance from the edge of the plate. The mounting plate itself should have a customizable thickness.

Can you generate the necessary OpenSCAD code for this? I'm familiar with the basics, but creating the correct math for the hexagon layout and tilt is a bit beyond me.  I'm also comfortable manually defining the mounting plate locations if there isn't an easier method.

I'd like to create a customizable, chamfered nameplate using OpenSCAD. I'm thinking it should work similarly to the "Chamfered_text_2_V6.scad" example I found, but I want a fresh implementation. Here's what I need:

*   **Text Input:** The design should allow for up to two lines of text input, `textstring1` and `textstring2`. If the second line is left blank, only one line should render.
*   **Font Selection:** The user needs to be able to choose from a wide variety of fonts, just like the example file. It would be great to have a similar list of font options, including some bold and thinner fonts, and the ability to specify the font name, such as "Nova Mono".
*   **Chamfered Edges:** The text should have chamfered edges. This effect is achieved by using the `minkowski()` function with a cylinder in the example, but a different method might be used if there's a better approach. The `scale` variable should affect the width of the chamfer.
*   **Text Height:** The height of the extruded text, `textheight`, should be customizable.
*   **Text Size:** The font size, `textsize`, should be customizable.
*   **Line Height:** The space between the two lines of text, controlled by `lineheight`, should also be customizable and measured in multiples of font size.
*   **No Libraries Required** I am not trying to use any special libraries, so just a single .scad file should be sufficient.

Basically, I'm after a clean OpenSCAD file that takes these parameters and creates the chamfered text plate, like in the example, but without relying on the existing code.

[Assistant]
Chamfered_text_2_V6.scad:
```
//Set the 1st textline to render
textstring1="A";

//Set the 2nd textline to render - or leave blank if only 1 line is needed
textstring2="B";

//Font name. In the list is first a selection of bold fonts. After the dashed line you get a list of thinner fonts, which are not really recommended.

Hi, I'm looking for an OpenSCAD design for a simple fridge bottle coaster. I keep having issues with bottles falling over on the wire shelves in my refrigerator.

Basically, I need a pot-like coaster with grooves on the bottom that fit the fridge shelf grid to prevent it from sliding around. The design should be parametric so that it can work with different shelf spacing and different bottle sizes. I'd like the option to specify how many of the same sized bottles to store in a row, too.

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

*   **`bar_spacing`**: The distance between the bars on the fridge shelf grid (in millimeters).
*   **`bar_width`**: The diameter of a single bar on the fridge shelf grid (in millimeters).
*   **`pot_height`**: The height of the coaster pot (in millimeters).
*   **`bottle_diameter`**: The diameter of the bottle that the coaster will hold (in millimeters).
*   **`flange`**: How much the bottom of the coaster is wider than the top (in millimeters). This is to add some stability.
*   **`number_of_pots`**: How many identical bottle holders to create in a row.

I also want to make sure that the design takes into account the usual considerations for 3D printing:
*   **`wall_width`**: The thickness of the walls of the pot
*   **`bottom_thickness`**: The thickness of the bottom
*   **`top_thickness`**: The thickness of the top rim
*   **`clearance`**: A small bit of extra space to make sure things fit properly
*   **`angle`**: Overhang angle; this is less a parameter and more something to keep in mind when you're designing it, to make sure the design is easily printable and not just a bunch of overhangs.

I'm not sure what libraries are most appropriate to use for a design like this, so I'm happy for you to make those decisions.  Could you create the necessary OpenSCAD files, please?

I want to design an ashtray that sits on top of a standard tin can, like a tuna can. The idea is to have a sturdy base made of the can itself (which is resistant to cigarette heat) and a 3D printed top that provides places to rest cigarettes. I'd like it to be parametric, so I can adjust the size for different cans.

Here are the key parameters I envision:

*   `od`: Outer diameter of the can.
*   `di`: Inner diameter of the can.
*   `h`: Outer height of the can.
*   `wt`: Wall thickness of the printed part.
*   `cd`: Diameter of the cigarette holders.
*   `nh`: Number of cigarette holders.
*   `lh`: Length of the cigarette holders.
*   `pretty`: A boolean (or 0/1) to control whether the edges are rounded.

The design should consist of a hollow cylinder that fits snugly over the can, both outside and inside, with a flat top. The cigarette holders should be angled, and they should project slightly over the edge of the main cylinder to allow easy placement of cigarettes. I'd like the user to be able to control if these holders have a smooth rounded section where they meet the rest of the ashtray.

I'm looking for a full OpenSCAD file (or files if that makes more sense for the project) that implements this design. I don't have any external libraries that I am using, but please feel free to suggest any if you think they'd be helpful in the design.

I'm looking for an OpenSCAD design for some customizable soft mounts for drone motors. I'd like to be able to adjust the following parameters:

*   **Center Element Diameter:** The diameter of the central circular part of the mount.
*   **Center Hole Diameter:** The diameter of the hole in the center, which should be smaller than the center element's diameter.
*   **Wall Thickness:** The thickness of the walls surrounding the screw holes.
*   **Screw Hole Diameter:** The diameter of the screw holes/slots.
*   **Outer Screw Diameter:** The maximum spacing between the screw holes (diameter).
*   **Inner Screw Diameter:** The minimum spacing between the screw holes (diameter).
*   **Mount Height:** The height of the mount.
*   **Shape:** The overall shape of the mount, which should be selectable between a cross shape and a circle.

I want a parametric design so I can easily change these values. The "cross" shape should be based on four arms extending out from the center, and each arm should have a slot for the motor screws.  The screw slots need to be elongated in a way that allows some adjustment for different motor mounting hole spacings.  The "circle" shape should be based on a circular pad.

The design should be a single file, and I don't need any special libraries beyond the standard OpenSCAD features.

Hey, I'm looking for an OpenSCAD design for a linear bearing mount, but I need it to be highly customizable. I've got an existing design I'm working from, but I'd like a fresh, parametric version created from the ground up.

The mount needs to hold an LM8UU linear bearing (or similar, like an igus RJ4JP-01-08).  It should have four mounting points for M4 screws and nuts, and these need to be counterbored for the nuts. I'd like to be able to adjust the following parameters:

*   **Nut Notch Size:** This controls the size of the recess for the nut, and needs to be adjustable because not all nuts are perfectly the same size. Default should be 7.1mm (suitable for M4 nuts).
*   **Nut Notch Depth:**  The depth of the nut recess. The default should be 3.2mm (for M4 nuts).
*   **Nut Insert Bevel Bottom:**  The height of the bevel at the bottom of the nut recess. Default of 0.
*   **Nut Insert Bevel Top:**  The height of the bevel at the top of the nut recess. Default of 3.2 mm.
*   **Through Diameter:** The diameter of the through-hole for the M4 screw. The default should be 4.5mm.
*   **Bearing Diameter:** The diameter of the linear bearing. The default should be 14.8mm, and I'd like to be able to adjust this.
*   **Bearing Height:** The height of the linear bearing. The default should be 32.2mm, and I'd like to be able to adjust this.

The overall shape is kind of like a platform with a cylindrical cutout for the bearing. The platform needs some ribbing for strength and four corner cutouts, and should look generally like the one in the provided SCAD code but a more robust/cleaner design is preferred. I’d also like to adjust the size of the base platform so it can be used with different projects.

I’m not sure how to handle this within the code myself, but I was hoping the AI could generate a parametric version of this? Could the AI also provide comments explaining each of the modules? It would be awesome to get something relatively straightforward to customize and easy to understand. I’m hoping to not use any outside libraries or modules. It would be really helpful if the generated scad included the $fs and $fa variables as well.

Thanks so much!

Hey, I'm looking to design an LCD bezel for a 3D printer. I've got some measurements and requirements, and I'd like it to be parametric so I can adjust it if needed. I've seen some existing designs, but I want one that specifically fits my needs. Here’s what I have in mind:

First, the bezel needs to fit between an LCD screen and the housing it sits in. I need to be able to specify the following dimensions:

*   **display_width:** The actual width of the LCD screen itself.
*   **display_height:** The actual height of the LCD screen.
*   **housing_width:** The width of the opening in the housing where the LCD fits.
*   **housing_height:** The height of the opening in the housing.
*   **bezel_x_out:** The outer width of the bezel.
*   **bezel_x_in:** The inner width of the bezel opening (where the screen shows through).
*   **bezel_x_offset:** An offset for the bezel along the x-axis, so the bezel isn’t necessarily centered on the housing opening. 0 will center it.
*  **bezel_y_out:** The outer height of the bezel.
*   **bezel_y_in:** The inner height of the bezel opening.
*   **bezel_y_offset:** An offset for the bezel along the y-axis, also 0 to center.
*   **bezel_thickness:** The thickness of the main, visible face of the bezel.
*  **lcd_recess:** How much the LCD is set back behind the housing's surface. Use 0 if it's flush or protruding.
*  **lcd_protrude:** How much the LCD sticks out from the housing, set to 0 for recessed or flush.
*   **mount_depth:** How deep the bezel mounts into the housing – this will be for the friction fit part.
*   **mount_x_offset:** An offset for the mounting section along the x-axis, where 0 is center.
*   **mount_y_offset:** An offset for the mounting section along the y-axis, also where 0 is center.
*   **wiggle_room:** The tolerance for the mount, so it’s not too tight of a fit.

I need an OpenSCAD file that creates this bezel. The bezel should be designed with a faceplate that’s visible and then the mount that goes into the housing. The faceplate should have an opening that is the size of `bezel_x_in` and `bezel_y_in`, and an outer size of `bezel_x_out` and `bezel_y_out`. The mount should fit inside the housing opening, but be slightly smaller than that opening, and it should have a hole in the middle for the LCD to pass through. The LCD screen area should match the size of the LCD and account for any recess or protrusion.

I'm not looking for any complex or advanced features, just a good way to generate this parametric bezel, and I think basic OpenSCAD functionality should be fine. I’d like the final object to be a union of the faceplate and the mount. Could you help me with that?

Okay, I need a cookie cutter generator, but not just any cookie cutter. I want to be able to make a gingerbread man cookie cutter, but I want *lots* of control over the shape. I've seen some examples, but I want one that's completely customizable, with all sorts of parameters for the limbs, head, and body. I also want to be able to add support bars to the design if I need them.

Specifically, I want to be able to adjust the following:

*   **Head:** Diameter of the head.
*   **Body:** Height and width of the main body.
*   **Arms:** Length and width of the arms, and angles for both the upper and lower arm segments (at the shoulder and elbow). I need to be able to pose the arms.
*   **Legs:** Length and width of the legs, and angles for both the upper and lower leg segments (at the pelvis and knee). The legs need to be poseable too!
*   **Neck:** The angle that the head is tilted at.
*   **Symmetry:** A setting to mirror the limbs in different ways: either swap right and left, mirror only the right limbs, or mirror only the left limbs. Or have no mirroring.
*   **Cutter:** The depth of the cutter, the thickness of the sides, and the thickness of the cutting edge.

I also want the ability to add cross bars to the cutter, in case the outline becomes isolated. Each cross bar should have its own set of parameters: activate on/off, width, X and Y translation, and an angle.  I want to be able to use several crossbars.

Finally, I need a way to flip the cutter upside down for printing reasons.

I'd like the code to be well-commented, so I understand each part, and I would love it if all the settings were displayed in the console as numerical values after rendering, so I could double check things.

Can you provide a parametric OpenSCAD file (or files) that can do all this? I don't need any special libraries.

Hi there! I'm looking to design a parametric wind gauge, and I'd like your help creating the OpenSCAD files. I've been experimenting, and I have a pretty good idea of the structure, but I need it to be flexible based on a few parameters. I'm hoping you can generate the .scad files.

The basic design is a vertical mast with one or two levels of wind catchers, each composed of several angled "scoops" or blades attached to arms. I'm also going for a design that avoids using actual ball bearings, with a printable replacement instead.

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

**Global Parameters:**
*   `part`: A string that determines which part to render. Options should be `"wind_catcher_1"`, `"carrier_1"`, `"mast"`, `"assembled_1"`, `"wind_catcher_2"`, `"carrier_2"`, and `"assembled_2"`.
*   `wcr`: An integer to control the rounding of the wind catcher pyramid. Range: 0 to 19.

**For the first (main) wind catcher level:**
*   `r`:  The length of the arms from the center. Range: 30 to 100.
*   `dw`:  The angle between the arms, which controls the number of wind catchers.  I'd like to have pre-sets for 120 (3 arms), 90 (4 arms), 72 (5 arms), and 60 (6 arms).
*   `hsl`: The radius of each wind catcher "scoop." Range: 20 to 100.
*   `al`: The length of the mast below the first level. Range: 40 to 180.

**For the second wind catcher level (if present):**
*   `r2`: The length of the arms from the center for the second layer. Range: 30 to 100.
*   `dw2`: The angle between the arms for the second layer, controlling the number of wind catchers (same angle options as `dw`).
*   `hsl2`: The radius of the second layer's wind catcher scoops. Range: 20 to 100.
*   `al2`: The length of the mast between the two layers of wind catchers. Range: 30 to 180.

**Specific Components:**

*   **"KugellagerErsatzM" and "KugellagerErsatzW"**: These are the printable replacements for the ball bearings (male and female parts, respectively).  The male part should have a height parameter.
*   **"Pyramide"**: This is the basic shape of the wind catcher scoop, a pyramid, with optional rounding at the corners controlled by `wcr`.
*   **"Schaufel"**: This is the full wind catcher scoop, incorporating the pyramid, mounting features, and some internal support. It should accept `r` as an argument, as well as an optional brim toggle (`brim`). The length of the mounting arm should be calculated based on `r`.
*    **"Schaufelhalter"**: This is the piece that holds the wind catcher scoops and attaches to the mast. It should accept `r`, `dw` and brim as parameters.
*   **"Schaufelhalter2"**: This is the same as "Schaufelhalter," but includes the connection to the second mast and accepts 'h' (height) as a parameter.
*   **"Rohr"**: This is a general module to create a hollow cylinder with inner radius `r`, wall thickness `w`, and height `h`.
*   **"Achse"**: This is the vertical mast, also incorporating the male ball bearing replacement at the top, and should take height `h` and an optional brim toggle (`brim`).
*   **"zusammengebaut"**: This module should combine the mast, carrier and wind catchers of the first level. The parameters are all of the main parameters for the wind catcher and mast (`r`, `dw`, `hsl`, `al`).
*   **"zusammengebaut2"**: This module should combine all parts for a two-layer wind gauge. The parameters are all the parameters for the wind catchers and masts (`r`, `dw`, `hsl`, `al`, `r2`, `dw2`, `hsl2`, `al2`).

I'm not looking to use any external libraries for this project. I think all the needed geometry can be generated with standard OpenSCAD functions. It's important that the design is robust enough to handle some minor variation when 3D-printing.

Let me know if you have any questions!

Hey, I'm looking to get some OpenSCAD code for a parametric button guide, kind of like a bezel or trim that helps stabilize loose buttons. I have a design I've been using, but I need it generated from scratch, and a little bit more robustly.

Here's the breakdown of the features I need:

*   **Bezel:** This is the outer part of the guide that will sit flush against the housing. I need to be able to set its thickness and diameter.
*   **Mount:** This part goes inside the housing hole where the button sits. I need to be able to specify the diameter of this mount (it should be a snug fit), and its depth. I also need to be able to offset it from the center, in case my housing hole isn't directly centered.
*   **Button Guide:** This is the hole through the center of the guide. I need to be able to set two diameters for this guide, one at the base (where it meets the mount) and one at the top (where it meets the bezel). This is so I can accommodate conical shaped buttons.
*   **Bevel Recess:** I need to be able to create a shallow bevel recess on the top side of the bezel, kind of like a chamfered edge to help guide the button a little bit. I need to specify the diameter of the recess and its depth.

I'd like to have all of these as user-definable parameters, and I think it would be awesome if the code were designed to be modular and fairly readable. Also, I'd like to be able to generate it within a customizer, so make sure all parameters are accessible.

Essentially, what I am looking for is a single module that generates the entire part.

I don't have a preference of library usage for this project, so please use whatever you think is most appropriate.

Let me know if you have any questions.

I need a customizable cable clip generator for both 2020 and 3030 aluminum extrusion profiles. The clips should be circular and attach to the extrusion's channel. I'm looking for the following parameters to be adjustable:

*   **Profile Type:** Either 2020 or 3030.
*   **Inner Size (Diameter):** The diameter of the opening for the cables to pass through.
*   **Wall Thickness:** The thickness of the clip's wall.
*   **Height:** The height of the clip.
*  **Center Offset:** An offset along the x-axis for the circular cable channel, where 0 is centered on the extrusion.

The design should have a cutout to allow cables to be inserted into the circular channel without needing to thread the cable through. The circular part should always sit above the extrusion's channel with an appropriate amount of clearance. The center offset should be limited so that the circular part of the clip remains within the width of the extrusion.

I'd like to be able to download each generated cable clip in .stl format. Also, It would be good to be able to render the clip before downloading.

I don't have any specific requirements for the libraries but it should be as efficient as possible and should avoid any unnecesary code. Also, the code should be well structured.

I'd like to create a heart-shaped jewelry box with a customizable design. I need to be able to adjust the overall size of the box, the height of the base and lid, and the thickness of the walls. I'd also like a few different heart shape options to choose from.

Specifically, I envision these parameters:

*   `box_size`:  A single dimension to control the overall size of the box (e.g., a 100mm box would be 100mm wide, and roughly 100mm tall).
*   `base_height`: The height of the main box portion.
*   `cap_height`: The height of the lid.
*   `box_shape`: An integer to choose between different heart shapes (e.g., 1 for a classic heart, 2 for a heavy heart, 3 for a thin heart, and 4 for a more curved heart).
*   `bottom_wall`:  The thickness of the bottom wall of the box.
*   `top_wall`: The thickness of the top wall of the lid.
*   `side_wall`: The thickness of the side walls of both the box and lid.
*   `cap_to_body_inserting`: The length of the lid's lip that fits into the base.
*   `cap_to_body_gap`: A small gap between the lid and base for easy fit.

I'd like the code to generate two main parts: the base and the lid. The lid should fit snugly into the base, and I'd like to be able to control how much it inserts. The different heart shapes can be generated using imported data points to polygon functions.

Could you generate the necessary OpenSCAD files for this? I'm thinking this will probably need multiple modules, and I'd like to be able to use the parameters defined above.
