Hey, I'm looking to create a customizable reading block toy, kind of like the Montessori phonetic reading blocks, and I need some help designing the OpenSCAD files for it.

Here's what I'm thinking:

**Core Components:**

*   **Blocks:** I need a cube-shaped block that can be customized with letters on all four sides. The block size should be parametric. I'll need to specify the letters on each side as well.
*   **Bolt:**  This will be a threaded rod that the blocks can stack onto. The bolt should have a head and a threaded portion, with the length of the non-threaded portion being determined by the number of blocks used. The bolt's dimensions (head diameter, head height, thread diameter, thread step, thread length) should all be customizable. The bolt should also feature a countersink to accommodate the nut.
*   **Nut:** A matching nut to screw onto the end of the bolt to hold the blocks in place. It should have corresponding threads and be designed with hex faces for easy turning and adjustable dimensions like diameter and height.
*   **Lettering:** I'd like to use a specific font (like "Liberation Sans"), a customizable letter size, and a defined letter height for the lettering on the blocks.

**Customization Parameters (User-Defined):**

*   `type`: (enum) To be able to chose between generating "Nut", "Bolt", and "Block"
*   `number_of_blocks`: An integer to specify how many blocks are needed. This will impact the length of the bolt's non-threaded section.
*   `First_Letter`, `Second_Letter`, `Third_Letter`, `Fourth_Letter`: Strings to specify the letters on each face of the block.
*   `block_size`: The length of one side of the cube block.
*   `letter_size`: The font size of the letters on the block.
*  `letter_height`: The height that the letters should be extruded from the block
*   Bolt Parameters:
    *   `head_diameter`, `head_height`, `drive_diameter`, `slot_width`, `slot_depth`, `thread_outer_diameter`, `thread_step`, `step_shape_degrees`, `thread_length`, `countersink`, `non_thread_length`, `non_thread_diameter`
*   Nut Parameters:
    *   `nut_diameter`, `nut_height`, `nut_thread_outer_diameter`, `nut_thread_step`, `nut_step_shape_degrees`
*    `resolution`: Affects the precision of the model.
*   `nut_resolution`: Affects only the nut.

**Functionality:**
* The bolt should be parametric to allow for an expansion of the toy.
* The blocks should have the letters placed in a manner where they are readable.
* The nut should fit snugly onto the bolt.
*The code should be easily customizable through the customizer.

**Libraries:**
* No libraries needed.

I'd like separate modules for the screw threads, bolt head, nut, and block, which will be combined in the main module based on the user's selection of "Nut", "Bolt", or "Block" to output.

Could you generate the necessary OpenSCAD files?

I'm looking to create a parametric die wrench for threading small bolts, kind of like a palm ratchet but without the ratchet mechanism. I've found a basic SCAD file that I like the general idea of, but I want to improve upon it and make it more robust and customizable. It's currently a double-sided wrench for 1" and 5/8" dies, but I want to easily adapt it to other sizes.

Here's a breakdown of what I need in a parametric design:

1.  **Overall Shape:** It should be a roughly cylindrical design with die cutouts on opposing faces.
2.  **Die Cutouts:**  I need to be able to specify the flat-to-flat width and thickness for *two* different die sizes. The cutouts should be hexagonal, accommodating standard hex dies, and have a slight tolerance adjustment parameter. It'd be great if the hex cutouts are generated using the `polygon` function so that it can be easily customized.
3.  **Handle:** The main body should have a diameter that I can control, and the height should be based on a total height parameter. I also like the finger notches idea to get a better grip, so they should be included, with adjustable diameter, number, and distance from the center.
4.  **Parameters:** I want to be able to control all of the above:
    *   `total_height`:  Overall height of the wrench.
    *   `die1_width`: Flat-to-flat width of the first die.
    *   `die1_thickness`: Thickness of the first die.
    *   `die2_width`: Flat-to-flat width of the second die.
    *   `die2_thickness`: Thickness of the second die.
    *   `die_width_adj`: Tolerance adjustment for die width (e.g., 1.01 for 101%).
    *   `finger_notch_dia`: Diameter of the finger notches.
    *   `finger_notch_dist`: Distance of the notches from the center.
    *   `finger_notch_count`: The number of finger notches around the handle.
    *  `handle_dia`: the outer diameter of the main body
    * `render_offset`: A small value for making cuts look cleaner.
5.  **Libraries:** I'm not using any special libraries, so this should be doable with base OpenSCAD functions.

I'd like this to be flexible enough that I can tweak it for various dies.  A single .scad file would be ideal. Thanks!

I'm looking to create a parametric propeller guard for my Parrot ANAFI Thermal drone, and I'd like to use OpenSCAD. I have some specific design parameters and a few different guard shape options in mind.

First, the main guard should be a circular shape with a configurable radius, which I'll call `fanguard_radius`. I'd like to be able to adjust this between 65 and 100, with a default value around 70. The vines, or struts, of the guard should also have configurable width and height, `fanguard_width` and `fanguard_height` respectively. I think `fanguard_width` should be adjustable from 1.5 to 10 with increments of 0.5, and a default of 2.5. The height, `fanguard_height`, can be adjusted from 2 to 5, in increments of 0.5, with a default of 3.

Now for the guard shape itself, I want to be able to choose between a few different patterns, controlled by a variable `fanguard_armType` which can take the values 0, 1, 2, or 3.
 * 0 would mean no guard at all
 * 1 would create a simpler guard with straight edges intersecting the main circle
 * 2 and 3 would be more complex, with the edges angled and possibly scaled. I'm not quite sure of the exact scaling, but you can see the shapes I mean in the attached `ANAFI_PropellerGuard.scad` file.

Also, I need a way to attach the guard to the drone's arms, using some sort of hagger or locking mechanism. The hagger itself should have adjustable dimensions `width_upper`, `width_lower`, `length_upper`, `length_lower`, and `length_lock`. `width_upper` should range from 17 to 21, `width_lower` from 12.5 to 16.5, `length_upper` from 5 to 8, `length_lower` from 2.5 to 5.5, and `length_lock` from 25 to 28, all in increments of 0.1. Default values of 19, 14.5, 6.5, 4, and 26.5 respectively should be fine.

I'd also like some logic to handle the folding of the guard. A boolean parameter `isFineFolding` should control a rotation of the hagger for fine-tuned folding. The rotation amount for fine-tuning should be derived using `fanguard_height` using the formula `atan(fanguard_height/40)`.

Finally, I'd like a debug mode controlled by the boolean `isDebug`. This would display multiple copies of the guard in various orientations, to help visualize overlapping when folded, as you can see in the attached example `ANAFI_PropellerGuard.scad`. If `isInvert` is true, the whole model should be rotated 180 degrees around the X-axis for optimal printing.

Could you generate the necessary OpenSCAD files to implement all of this? I am not using any specific libraries like BOSL, MCAD or similar, so the code must be fully self-contained.

[User]
I want to design a modular LED strip mounting system with an optional diffuser, all parametric for easy customization. I've got some basic ideas and measurements already figured out, and I'd like to be able to adjust things like the rail size, diffuser thickness, and clearances.

Specifically, I envision a rail that holds the LED strip, and then a separate diffusor that can snap onto it. The rail will have a main base part that rests on the mounting surface, and then a raised section with hooks to hold the LED strip in place. I need to be able to adjust the angle of the base relative to the mounting surface (e.g., for angled wall mounts). I will be 3D printing it.

I want a single OpenSCAD file or a minimal set of files which handle this LED strip mount system. I'd like the main parameters to be exposed in the OpenSCAD customizer, and I'd also like to be able to individually generate STL files for the rail and diffuser, either with solid fills or with a specific wall thickness for less material usage.

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

**General:**

*   `height`: Overall height of the rail and diffusor when extruded (for linear extrude), defaulting to 100, but should be able to be set to 0 for non-extruded 2D versions.
*   `hollow`: Boolean (yes/no) to choose between solid and hollow parts with wall thickness, defaulting to no.
*   `rail_wall`: Wall thickness for the rail if `hollow` is "yes", defaulting to 0.8.
*   `angle`: Angle of the rail base relative to the mounting surface in degrees, defaulting to 30.
*   `offset_x`, `offset_y`: Offsets for positioning, defaulting to 0, although offset_x ideally needs to be zero for all generated parts.

**LED Strip Rail:**

*   `strip_width`: Width of the LED strip, defaulting to 10.0.
*   `strip_clearence`: Clearance between the LED strip and the rail walls, defaulting to 0.2.
*   `strip_border_height`: Height of the borders that hold the LED strip, defaulting to 2.0.
*   `strip_border_width`: Width of the borders that hold the LED strip, defaulting to 1.2.
*   `strip_hook_width`: Width of the hook that secures the LED strip, defaulting to 0.7.
*   `strip_thickness`: Thickness of the rail material holding the strip, defaulting to 0.8.

**Rail Base:**

*   `profile_slot_width`: Width of the slot for mounting rail in profile. Defaults to 6.2.
*  `profile_thickness`: Thickness of the profile where it interfaces with a slot. Defaults to 2.0.
*  `profile_tooth_edge`: Width of the teeth that interface with the slot. Defaults to 0.7.
* `profile_tooth_depth`: Depth of the teeth that interface with the slot. Defaults to 2.0.
*   `profile_slot_pressure`: Amount of extra width in the rail slot to provide for a pressure fit, defaults to 0.3.
*   `profile_clearence`: Clearance between profile and base, defaults to 0.2.
*   `profile_edge_min_width`: Minimum width of the profile edge. Defaults to 2.0.

**Diffusor:**

*   `enable_diffusor`: Boolean (yes/no) to enable the diffusor or just render a basic rail, defaulting to yes.
*   `diffusor_wall`: Thickness of the diffusor walls, defaulting to 0.8.
*   `diffusor_slot_depth`: Depth of the slot in the rail that holds the diffusor, defaulting to 1.0.
*   `diffusor_holder_wall`: Thickness of the diffusor holder walls, defaulting to 1.2.
*   `diffusor_pressure`: Additional space on the holder to make diffusor fit tightly, defaulting to 0.3.
*   `diffusor_clearence`: Clearance between the diffusor and the rail, defaulting to 0.1.

I'd like a `demo` mode where the rail and diffusor are shown together in different colors.  Also, I'd need to be able to generate just the `rail` or just the `diffusor` part from the same code.

I don't need any external libraries, just standard OpenSCAD features should be fine.

I'm looking to design a tapered, frustum cone, but I want to be able to make it from several different segments.  I'd also like the option to add a lip at the base and a screw thread on the top. I need to specify all dimensions in inches, and I need to specify the number of segments it will be composed of, so it won't always be just one piece.

So basically, I need a parametric OpenSCAD design that lets me specify:

*   **Base Diameter (in inches):** The diameter of the widest part of the cone
*   **Top Diameter (in inches):** The diameter of the narrowest part of the cone. If it's set to 0, then it is a complete cone with a point
*   **Overall Height (in inches):** The total height of the entire cone.
*  **Number of Segments:** How many segments the cone will be broken into. Each segment will be the same height.
*  **Base Lip Height (in inches):** How tall the lip is at the base (if any).  0 for no lip
* **Base Lip Thickness (in inches):** How thick the lip is at the base. 0 for no lip
* **Screw Thread Diameter (in inches):** The nominal diameter of the threads
*   **Screw Thread Pitch (in inches):** How far apart the threads are
*   **Screw Thread Length (in inches):** How much of the top of the cone will have threads

I'd like to use the `thread` module from the [BOSL2](https://github.com/BOSL2/BOSL2) library, and I guess standard `cylinder()` calls for the main cone body. I also assume we'll need a `union()` and a `difference()` to make everything work.

I also need each segment to be printable so I want the design to account for this by offsetting each segment up so that they stack on top of each other when printed and not on top of each other in the coordinate system. It needs to be possible to print each segment individually.

I think that covers everything. I'm not sure if that's one file or several, but I'd like to see your implementation.

I'd like to design a 90-degree pipe connector for a project I'm working on. It needs to be parametric so I can adjust it for different pipe sizes and spacing.

Here are the key features I need:

*   **Two Pipe Holes:** It should connect two pipes of the same diameter at a 90-degree angle.
*   **Press-Fit Design:** I want it to have a press-fit design, so the pipes fit snugly.
*   **Fixing Holes:** Include small holes that can be drilled out for bolts to secure the pipes.
*   **Adjustable Dimensions:** I need to control several parameters:
    *   **Pipe Diameter:** The inner diameter of the pipe holes.
    *   **Pipe Offset:** The distance between the centers of the two pipes.
    *   **Wall Thickness:** The thickness of the connector walls.
    *   **Wall Chamfer:** The size of a chamfer on the outer edges.
    *   **Fixing Bore:** The diameter of the fixing holes.
    *   **Gap Size:** The size of a gap around the pipe holes for a better press fit.
*   **Printability:** It should be designed to print vertically without supports.  I'm imagining a bridge at the top of each pipe hole with some gap extending past the pipes.
*  **Libraries:** I'm comfortable using MCAD for any math or common parts, but otherwise, please don't use external libraries.

I'm hoping the OpenSCAD code will be well-structured and easy to modify. I'd like it in a single .scad file if possible. Thanks!

I'm looking to create a parametric design for a structural arm that clamps onto two pipes at right angles to each other. Imagine two pipes, one running horizontally and the other vertically. I want an arm that wraps around each pipe, kind of like a C-clamp, and connects the two.

Specifically, I need these parameters:

*   **Pipe Diameters:**  The diameters of both pipes should be adjustable. Let's call them `pipe1_diameter` and `pipe2_diameter`.
*   **Arm Width:** This is the thickness or width of the arm material itself. Let's call it `arm_width`.
*   **Arm Height:** This will be the height of the arm at the top and bottom of the pipe. Let's call it `arm_height`.
*   **Arm Gap:** This is the gap between the pipe and the arm. Let's call it `arm_gap`. This value will create a press-fit connection.
*   **Center Distance:** The center distance between the two pipes should be adjustable, I want to be able to offset them from each other, this will be a 2D vector `center_offset`.
*   **Arm Offset**: I want to offset the arm from the center of the pipes, along the axis of the pipe, this value will be a 2D vector `arm_offset`.
*   **Wall Thickness:** I'd like to be able to define a wall thickness for the main body of the arm as well, call this `wall_thickness`.

The arm should be a solid piece that's formed by the union of two clamping sections that wrap around the pipes and a connecting piece. The clamping sections should be roughly "C" shaped, or partially circular, that allows the arm to be pressed onto the pipes.

Could you generate the OpenSCAD code for me? I'm not using any custom libraries, but I'm comfortable using the standard OpenSCAD library.

Hey, I'm looking to create a customizable cache container that fits on top of rectangular posts. I've been tinkering with some code, but I think a parametric design would be better. I'd like to be able to define a few key dimensions and have the OpenSCAD model adjust accordingly.

Specifically, I need to control:

*   **`capdia`**: The diameter of the circular opening where the actual cache container will sit.
*   **`capheight`**: The height of that circular opening.
*  **`postwidth`**: The width of the rectangular post it's going to sit on.
*  **`postlength`**: The length of the rectangular post.
*   **`elementheight`**: The overall height of the rectangular base that fits over the post, and which the cap sits on top of.
*  **`wall`**: The thickness of the walls all around.

The design should have a rectangular base with a hole in the middle that fits snugly over the post, and a circular receptacle on top where the cache container can sit. The base should sit atop the post, and the receptacle should be centered on the base. I'd like for there to be a small lip where the top of the base meets the post, so that it doesn't slide off. There should also be internal walls, where the post is located, which are a `wall` thickness on all sides. Also, the actual circular hole for the container should be `capradius` with a `wall` thickness all around. This should probably use a cylinder and a cube, and difference() operations.

Could you generate a parametric OpenSCAD file for this? I don't need any libraries, just a single .scad file with variables at the top. Please make sure it checks for nonsensical configurations like the cap opening being larger than the post dimensions, or the cap height being taller than the base height, and issues an echo statement if those occur.

// Elements height

// Wall strength

    echo ("Capheight higher than elementheight. Please change it.");

Hey, I'm looking for help designing a dice tower and storage solution. I've seen some cool designs out there, but I'd like something that's a bit more customized and uses parametric design principles so I can tweak it later. I was particularly inspired by the design from Platcham but wanted to make a few key changes.

Essentially, I'd like to create a set of OpenSCAD files that produces a system with a lower tray, an upper tray, a drawer for holding dice sets, a tower for rolling dice, and a peg for securing the drawer. The tower should sit on top of the lower tray, and everything should fit nicely together, using magnets. Here's a breakdown of what I'm imagining:

**Core Components:**

*   **Drawer:**  This is where the dice sets will be stored. It needs to have multiple slots to hold the sets, and also needs a handle for easy access. The size and number of slots should be adjustable. It should be able to slide into the lower tray. Also, there should be an option to add labels to the outside edge of the drawer (either front to back or back to front labels).
*   **Lower Tray:**  A base to hold the drawer, the tower, and the upper tray. It should have a recessed space for the drawer to sit in and should use magnets to secure the other parts.
*   **Upper Tray:**  A cover that sits on top of the lower tray and holds the tower in place with more magnets. It should have finger holes or some kind of cutout for easy removal.
*   **Tower:** This will be the dice rolling mechanism. It needs to have baffles inside to randomize the dice and an exit at the bottom that allows the dice to roll out onto the tray.
*   **Peg:** This is a small piece that prevents the drawer from sliding out when transporting the whole system. It can be printed flat.

**Key Design Parameters:**

*   **`DDie`**: The diameter of a standard D20, which should be adjustable so I can use it with dice of different sizes. Should be used in creating the dice slots in the drawer.
*   **`Sets`**: The number of dice sets the drawer needs to store. Should drive the number of slots in the drawer.
*   **`LSet`**: The length of one set of dice (i.e. the length of the slots in the drawer). Should be adjustable.
*   **`DMag`**: The diameter of the magnets.
*   **`ZMag`**: The thickness of the magnets.
*   **`Cutouts`**: A boolean switch to include or exclude decorative cutouts, such as arches or diamonds.
*   **`Deco`**: A boolean switch to include or exclude decorative textures, such as brick patterns and text labels
*   **`thk`**:  The thickness of the standard walls and floors in the model. Should be used for the majority of walls.
*    **`THK`**: The thickness of walls and floors in areas of high stress. Should be used for areas where more strength is needed.
*   **`part`**: A string that allows me to choose which part to generate ("Lower_Tray", "Upper_Tray", "Drawer", "Tower", "Tower_Back", "Tower_Front", "All_Packed", "All_Assembled", "Peg").

**Other Important Considerations:**

*   **Magnets:** The design needs to accommodate the use of cylindrical magnets (specified by `DMag` and `ZMag`). Should also be configurable so that the magnets can be omitted.
*   **Assembly:** The parts should fit together well, with enough clearance to allow for variations in printing. There should be alignment features for gluing pieces together, and the peg needs to lock in place with the tower.
*   **Aesthetics:** It would be nice to have options for decorative cutouts and surface textures, as mentioned earlier (`Cutouts`, `Deco`).
*   **Customization:** I'd like to be able to easily adjust the overall size, number of dice sets, and other dimensions through the parameters listed above.
*   **Baffles:** Tower baffles should be at the correct angle to randomize the dice, and should also be offset slightly to provide adequate space for the dice to roll.

I think that covers most of it. Could you generate OpenSCAD files that would handle this design? It'd be great if the design also takes into account alignment features.

I need to create a customizable button for 3D printing, and I'd like it to be parametric so I can easily adjust it for different projects. I'd like to be able to control the overall diameter, the thickness, the diameter and number of mounting holes, the distance of those holes from the center, the size of any outer rim, and how rounded the edges are. I'd like for the design to make a best guess at hole placement if I don't specify a distance to center.

More specifically, the button should start as a cylinder, then have the appropriate rounded chamfered edges subtracted out. Mounting holes should be cylinders that pass all the way through the button.

I think I would like parameters for:

*   `diam`: The overall diameter of the button.
*   `thick`: The thickness of the button.
*   `holepos`: The distance of the mounting holes from the center of the button.  If this is `-1`, the script should automatically calculate a good distance based on the `holediam` and `holecount`. The automatically calculated value should also never put the holes closer to the center than a distance equal to 1/8th of the overall diameter, `diam/8`.
*   `holediam`: The diameter of the mounting holes.
*   `holecount`: The number of mounting holes.
*   `rim`: The width of a small outer rim on the top face of the button. If `rim` is zero, no rim is added.
*   `smoothby`:  A value to control the radius of the rounded edges on the top face of the button. This value must be less than half of `thick`, and if it's greater than `thick/2`, it should be automatically set to `thick/2 - 0.001`.

I think I want to make sure that there is a single module named `Button`, that can take all the above parameters. The basic construction will involve `difference()` with the outside shape produced by `rotate_extrude()`.

I don't need any special libraries; I'm hoping the basic OpenSCAD primitives will be enough.

I'm looking for an OpenSCAD design for a parametric battery box, with a lid and mounting flanges. I'd like it to be highly customizable for different cylindrical battery sizes and quantities, and also include options for mounting holes. Here's the breakdown:

**Core Requirements:**

*   **Parametric Battery Size:** The design must allow me to specify the length and diameter of the cylindrical batteries. I'll be using various sizes, like AAA, AA, C, D, and 18650, and need to be able to adjust these dimensions easily.
*   **Adjustable Cell Count:** The battery box should be able to hold a variable number of cells, ranging from 1 to at least 4 (or more if it's not too complicated).
*   **Lid:** The design needs a separate lid that fits snugly onto the box. I'd like a tolerance parameter to account for printer inaccuracies, and the lid should use some sort of overlapping lip/edge to secure itself onto the box.
*   **Mounting Flanges:** I need mounting flanges with holes that can be positioned at both the top and bottom of the box. I need to be able to define the size, position, and thickness of the flanges, as well as the diameter of the mounting holes.
*  **Terminal Considerations**: There should be space for a terminal, as described, created from strips of metal flashing that are bent into shape.

**Specific Parameters I'd like to be able to control:**

*   `Length`: Battery length in mm.
*   `Diameter`: Battery diameter in mm.
*   `Tolerance`: Gap between the box and lid in mm to allow for printer errors.
*   `Cell_Count`: Number of cells in the battery holder.
*   `Mounting_Hole_Height`: Distance between mounting holes, center-to-center, when using a vertical orientation.
*   `Mounting_Hole_Width_Offset`: Distance of the mounting holes from the battery cells.
*   `Mounting_Hole_Diameter`: Diameter of the mounting holes.
*  `Mounting_Flange_Thickness`: Thickness of the mounting flange

**Other Desired Features:**

*   Rounded corners and edges for a smooth finish. I'd like these to be customizable as much as possible (fillet radius).
*   Clear markings for battery polarity (+/-), both inside the box and on the outside where the wires connect.
*   Cutouts to ease battery removal and make space for cell connections.
*   Cutout to ease wiring.

It would be great if you could provide a well-commented and organized set of OpenSCAD files using these parameters. I'm not using any particular libraries right now and would prefer not to, if possible.
