Okay, I'd like to design a laser-cut box generator, but I want to add some new features to it and make it a bit more flexible. I've been using this simple one (attached for reference, I guess?), but I think we could make it a lot better.

Here's what I'm thinking:

1.  **Parametric Joinery:** I like the tabbed joinery from my example, but I'd like the ability to adjust the tab size and spacing independently, not just through a single "js" scaling factor. I'd also like different joinery options, like finger joints or even dovetails. I'm open to suggestions on the best way to approach those.
2.  **Rounded Corners/Edges:** I'd love a way to add rounded corners and edges to the box parts. This should be a parameter, so I can control the radius of the curves.
3.  **Lids/Closures:** I want the option to include a lid. It could be a simple friction-fit lid or something with a hinge (though maybe that's a bit too advanced for this first pass). Ideally, there would also be options for closure mechanisms (like a simple latch or a magnetic clasp), maybe with small cutouts to embed magnets.
4.  **Internal Dividers:** It would be super useful to have the option to add internal dividers or compartments to the box. This would also need to be fully parametric.
5.  **Material Thickness Variations:** I should be able to input the material thickness and have the design adjust accordingly, with separate parameters for kerf. I'd like it to allow not just for a single material thickness, but to have different material thicknesses for the base/top, sides and dividers.
6.  **Customizable Cutouts/Engravings:** I’d like to be able to easily add cutouts (for handles, cable passthroughs, etc.) and engravings (logos, text, etc.) on any surface, not just the top/bottom like in the current example.
7.  **OpenSCAD Libraries:** I’m comfortable using OpenSCAD libraries like BOSL2, so let's use those for some of the more complex features if it makes sense.

So, to summarize, I'm looking for a parametric box generator that allows for different joinery types, rounded edges, lid options (including hinges and closures), internal dividers, and customizable cutouts/engravings. It would be great if the design could be adjusted for varying material thicknesses. I'd prefer to use BOSL2 where appropriate. I also need the output to be a valid OpenSCAD file and be easy to customize.

Let me know if you need more information or if I'm asking for too much at once!

Hey, I'm looking to design a cyclone separator for my workshop, and I think I've got a good idea of what I need. I'd like to make it parametric, so I can adjust it for different size hoses and buckets. I've seen some designs out there, but I'm not sure where to start with the OpenSCAD code.

Here's what I'm thinking:

**Core Components:**

*   **Bucket:** The separator will attach to a standard bucket, like a 5-gallon bucket. I need to be able to adjust for the top and bottom circumferences and height. This will let me customize for a variety of different sized buckets.
*   **Blower Port:** This is where the air and dust will enter. It needs to be sized for a specific hose diameter, and I'd like a coupling section that gradually tapers to meet the hose. It needs a flange (plate) for affixing to the bucket.
*   **Sucker Port:** This is the output for the cleaned air. Again, this will have a flange (plate) for attaching to the bucket or lid, as well as a hose coupler.

**Key Parameters:**

*   `hose_diameter`: The inner diameter of the hose I'll be using.
*   `bolt_diameter`: The diameter of the bolts I'll use to attach everything.
*   `bucket_top_circumference`: The circumference of the bucket at the top.
*   `bucket_bottom_circumference`: The circumference of the bucket at the bottom.
*   `bucket_height`: The height of the bucket.
*   `part_thickness`: How thick the flanges/plates should be.
*   `hose_coupling_length`: The length of the hose coupling section.
*   `hose_coupling_taper`: The taper percentage for the coupling.
*   `blower_plate_factor`: A factor to make the blower plate bigger than the hose diameter.
*   `$fn`: The number of sides for circles.

**Specific Design Features:**

*   The blower port flange should be sized such that it extends beyond the hose diameter by the `blower_plate_factor`.
*   The coupling section of both the blower and sucker ports should taper to meet the hose.
*   The blower port should have mounting holes for attaching to the side of the bucket. I don't think these need to be evenly spaced - it might make sense to put them at some angle.
*  The sucker port should also have mounting holes, presumably evenly spaced.
*   The parts should be designed to fit flush against the bucket, so taking into account the curvature of the bucket would be ideal.
*   I'd like some example text printed, maybe on the bucket itself, so I can easily identify what bucket it's for. Something like "HD" and "5 Gallon".

Could you generate the OpenSCAD code for this? Also, I'm not very familiar with the available libraries; if there are any that could help with the design, please use them. I'm happy to install whatever I need to. I don't need to use any specific library.

Hey, I'm looking to create a parametric twister container, kind of like the one Make Anything demonstrated, but I want to be able to fully customize it. I've seen some OpenSCAD files that do this, and I'd love to get something similar. I'd like to specify things like the overall height of the twisting part, the amount of twist (in degrees from top to bottom), the number of sides on the polygon base shape (I want to use circles, regular polygons, and maybe even a simple hull of two circles), the maximum radius of the inner part, a smoothing radius to round out corners, the line width for printing (which will affect the gap between parts), the gap between the inner and outer parts, the vertical resolution (the height of each slice for the twisting), plus chamfer depth and height for the top and bottom edges. I also need a variable to specify the bottom height – this would effectively shorten the inner part to account for bottom layers.

The design consists of two parts: an inner and outer twister. I should be able to generate each of these separately, or both at the same time, or even an assembled view. I'd like to be able to set a variable to switch between generating just the inner part, just the outer part, both parts side-by-side, or the two parts assembled as a container.

The inner part should have a chamfer on both the top and bottom edges and a flat bottom surface that accounts for the bottom layers. The outer part should also have a bottom chamfer. The inner and outer parts should be solid (not hollow). I'll be printing these in vase mode.

Could you generate the OpenSCAD code for this? I'd prefer a single SCAD file to manage everything. I'd like to see comments explaining key parameters and the overall structure of the code.

Hey, I'm looking to get an OpenSCAD design for an allen key holder. I've got a few specific things I need, and I'd like it to be customizable using parameters.

Basically, it should hold a series of allen keys of different sizes, arranged in a row, and I'd like to be able to specify the sizes of the keys it will hold. I need the holder to have a cut at an angle to make it easier to grab the keys.

Here's what I'm thinking:

*   **Key Sizes:** The design should use an array parameter where I can list the diameters of the allen keys I want to store. For example, I might want it to hold sizes like 1.5mm, 2mm, 2.5mm, 3mm, and 4mm.
*   **Spacing:** A parameter to control the spacing between the holes for the allen keys.
*   **Thickness:** A parameter to set the thickness of the holder.
*   **Rotation:** A parameter to rotate the entire array of keyholes.
*   **Tolerance:** A parameter to control the extra space around each keyhole, so it's not too tight.
*   **Height:** A parameter to control the overall height of the holder.
*  **Cut Height:** A parameter to control the height of the angled cut along the length of the holder
*   **Cut Angle:** A parameter to control the angle of the cut.
*   **Body Shape:** I'd like two options for the main body shape. One should be a hull around the keyholes making a smooth body, the other should be a hexagon based on the keyholes, sort of like a gear. The code should use a comment to toggle between these shapes.
*   **Circular Keyholes:** The actual holes for the allen keys need to be circular with a set number of facets, which should be controllable with the `$fn` parameter in the `circle()` function. I'd like to be able to change that to increase the number of facets for a smoother circle if I need to.

Essentially, the design should create a series of circular holes based on the provided key sizes, and position these holes in a row, and then provide a cutting shape for the angled cut. Make sure it is fully parametric, and that it is easy to change the parameters to change the shape/size/features of the keyholder. I think that should do it. Let me know if you have any questions.

I'd like to create a vase generator, but with some specific features. I want it to be parametric so I can adjust things easily.

The base of the vase will be a regular polygon, and I need to be able to specify how many sides it has, as well as the radius of the circle it's inscribed in. I also want the polygon to be offset from the Z-axis by a certain distance.

The vase will be created by extruding the polygon upwards, and I'd like to be able to control both the height of the extrusion, and the twist applied to the shape as it extrudes. There should also be parameters to scale the top of the vase differently on the X and Y axes, relative to the base.

Finally, I need to be able to create multiple of these vase shapes arranged in a circle, and optionally have a central pillar. So I need controls for the number of base polygons and a flag to enable/disable the central pillar. I think I'll also want the shapes to rotate along the z axis by an equal amount.

Could you write me an OpenSCAD file for this? I'm new to OpenSCAD, so I don't have any libraries I use yet. It's fine if you need to use some libraries, but let me know what they are.

I'm looking to create a set of 3D-printable tools for making chopsticks, similar to the design I've seen online but I need a parametric design so I can adjust it easily. I'm picturing three main parts: a main block that acts as a template, a plane block that holds a small hand plane, and an end stop guide. The final output should be a chopstick with a taper and a prism-like end.

The main block should have a central channel to hold the chopstick blank and should also have guides to define the thickness and taper of the chopstick. I'd like to plane the chopstick blank in four stages. The first stage will bring a square blank down to the desired maximum thickness, which is initially equal to the start width of the chopstick. The next two stages will add the taper and trim the sides of the blank, and a final stage to make an octagonal shape prior to the end being cut. The plane block will house a small hand plane and should allow for smooth movement along the template block. The end stop should clamp onto the chopstick and allow for the end to be cut to the desired angle.

I'd like to be able to adjust several things: the overall length of the chopsticks, the starting width (at the handle end), the ending width (at the tip), the angle of the end cut, and the size of the initial blank material. I'd also like some adjustability in the spacing of the plane block. I want to use a metal rod to hold the whole assembly together, so there needs to be a central hole for that. Maybe I can also have a washer or something on the end to serve as an end stop. The central hole should be sized for an M6 bolt. It would be good to have a label that shows the length of the chopstick that the tool is set up for.

Here are some more specific dimensions:

*   **Chopstick Length:** User defined, but I'd like to be able to make anything between 200mm and 400mm.
*   **Start Width (Handle):** User defined, probably 5mm to 10mm.
*   **End Width (Tip):** User defined, probably 2mm to 10mm (but needs to be smaller than the start width).
*   **End Cut Angle:** User defined, probably between 0 and 60 degrees.
*   **Initial Blank Size:** User defined, probably 6mm to 15mm, and obviously a bit bigger than the start width.
*   **Tolerance for Smoothing:** User defined. This is the amount of "slop" that allows the plane to slide without binding.
*   **Plane Block Width:** User defined, probably 20mm to 100mm.
*   **Plane Nose to Blade Distance:** User defined, probably 20mm to 100mm.
*   **Plane Block Support Width:** User defined, probably 60mm to 250mm.
*   **Washer Thickness:** User defined. Probably 1mm to 3mm.
*   **Central Hole Diameter:** 7mm.

I think that covers everything! Can you generate an OpenSCAD file for this design? I don't have any libraries I want to use in particular, so please use whatever you think makes the most sense.

// chopstick (hashi) maker
// Neon22 - github

// User chooses:
//	- length of sticks,
//	- desired start and end diameters (taper)
//	- angle of end cut (45)
//	- amount of tolerance in initial blank for first cut operation

// Instructions:
//  - Assuming a taper from 7mm end to 5mm head (actually adjustable)
// Side1
//		- planes oversize blank to 7mm thickness
//		- user rotates blank by 90 and so planes two adjacent sides to get to 7mm
// Side2
//		- puts taper onto two sides
// 		- goes from 7-6mm
//		- user planes first two adjacent sides of blank
// Side3
//		- puts taper onto the other two sides
//		- goes from 7mm to 5mm final resulting in equal taper on all sides
//		- user planes remaining two adjacent sides of blank to final taper
// Side4
//		- v cut to bring into octagonal shape approximating round (sanding)
//		- user does all four diagonals of blank
// End cut
//		- end cut does diamond shape at handle end of chopstick(hashi)
//		- user attaches guide and inserts chopstick through top plate guide,
//		  cuts and rotates 4 times to get pointed (octagonal) end

// Lengths:
// - typically 210mm to 270mm, cooking chopsticks are longer.
// chinese 	- (kuaizi) longer (270) and thicker - do not taper as much as other two.
// korean 	- (jeotgarak, sujeo-with spoon) toughest and heaviest of them all. Medium taper.
// Japanese - (hashi-eating, ryoribashi-cooking, saibashi-serving)
//			- shortest, tapers more than others, taper closer to the end.
//			- can be ribbed near tip to grab fish.
//			- 23cm male, 21cm female, 30cm cooking.
// Perfect length is 1.5 times the distance between tip of your extended thumb and forefiner.

I'm looking to design a flexible bracelet using OpenSCAD, and I'd like it to be fully parametric. I want to control several aspects of the design, specifically:

*   **Overall Radius:** The intended radius of the bracelet when worn.
*   **Number of Segments:** How many individual segments make up the bracelet.
*   **Height:** The vertical height of each segment.
*   **Outer Segment Length:** The length of the outer, more exposed part of the segment.
*   **Inner Segment Length:** The length of the inner part of the segment that is closer to the wrist.
*   **Segment Angle Length:** The length of the angled, connecting portion of each segment.
*   **Width:** The overall width of the segment.
*  **Thickness:** The thickness of the material, creating the 3D effect.

I need a design where the segments connect smoothly to form a circle. The bracelet segments should have a consistent thickness and allow for a slightly overlapping interlock between segments, ensuring a smooth flex. I'd like to define a small margin for that overlap as a variable, maybe something like "o", which is probably around 0.1 to 0.2.

Also, the main segments should have a profile that is essentially a rectangle with the height, thickness and the outer/inner segment lengths, with angled connectors of the segment angle length, that link these rectangular regions together on the segment's sides. In other words the segments are connected by these angled parts.

I also want the bracelet to be created as a union of individual segments rotated around a center, to make it circular, rather than as a whole shape. The rotation step will be equal to 360 / num_segments.

Could you help me generate the OpenSCAD code for this bracelet design? I don't have specific libraries I need in mind, but please use whatever you think makes sense and clearly list them for me.

Hey, I'd like to get an OpenSCAD model for a guitar pick based on the Stylus Pick. It's a pretty unique design, so here's a breakdown of what I'm looking for, plus some parameters I'd like to control.

The pick has two main sections: a conical "picking" section at the very tip that transitions into a larger body, and then a cone section at the base for stability. The picking cone starts at a point and the top of that cone should be joined smoothly to the body; the base is joined to a larger support cone. The overall shape is kind of like a paddle with a cone on both ends when you look at it in profile, with a flat bottom when it's printed.

Here are the parameters I'd like to be able to adjust:

*   **`support_cone_height`**: The height of the cone that connects to the flat base.
*   **`cone_diameter`**: The diameter of the cone base (which is also the width of the body at that end).
*   **`picking_cone_height`**: The height of the cone that forms the actual picking tip.
*   **`body_thickness`**: The overall thickness of the paddle-shaped main body of the pick.
*    **`body_edge_thickness`**: The additional thickness at the edges of the main body. There is an offset that I want to control that creates a slightly raised rim; this should be controlled separately from the total thickness.
*    **`body_offset`**: The offset of the edge of the main body, in units of distance *per side*, relative to the main body. Note that this can be negative (as it usually is)
*   **`body_major_height`**: The height of the wider portion of the main body.
*   **`body_major_width`**: The width of the wider portion of the main body.
*   **`body_minor_width`**: The width of the narrower portion of the main body.
*   **`body_total_height`**: The overall height of the main body (from the base of the picking cone to the end of the main body).

I'd also want to have a boolean called `print_half`. If this is true, the code should only generate one half of the pick; otherwise, it should generate the whole thing. You'll need to use `rotate` and `mirror` or similar. I think `rotate_extrude` would make the conical portions a lot easier. Please ensure the conical sections join smoothly with the main body of the pick. The base of the model should lie flat on the print surface.

I think that's everything. Let me know if you need any clarification. I'm fine with the default `fn` being high, but it should be exposed as a parameter, also. I don't need any of the standard libraries for this, just something straightforward to get the basics right.

  hull() {
    translate([0, 0, body_thickness/2 - 0.01]) linear_extrude(0.01) offset(body_offset) pick_body();
    linear_extrude(body_edge_thickness/2) pick_body();
  }
}

I'd like to create a parametric toothbrush holder, similar to the one described on Thingiverse (thing:2246209), but I'm looking for a completely new implementation. I want to be able to customize several aspects:

First, the basics: the number of toothbrush slots, the space between each slot, and the overall height of the stand. Let's call these `number_of_toothbrushes`, `space_per_slot`, and `height`, respectively.

Then, for the toothbrush slots themselves, I need to be able to control the radius of the cutout at the top and bottom. Let's call these `top_radius` and `bottom_radius`.

I also need to be able to adjust the width of the stand at the top and the base. I'd call these `top_width` and `base_width`.

Finally, it'd be great if I could optionally add text labels to each slot, specifying the toothbrush owner's name. I'll need to be able to customize whether this is embossed or engraved, the text size, spacing, top margin, and the font (like in the original). So, parameters like `add_text` (yes/no), `text_type` (embossed/engraved), `toothbrush_owners` (a string with names separated by semicolons), `text_size`, `text_spacing`, `text_top_margin`, and `text_font`. It would be great if you could handle a comma separated string of names for `toothbrush_owners`.

The stand has some rounded corners that should be generated with `hull()` to create a smooth transition between different shapes. I'm not sure if that helps, but it's in the original code. It also has some "fudge" factors based on the width of the base/top, so make sure to parameterize those as well.

I'm hoping you can generate this all in OpenSCAD as parametric design so it's easy to change all of these things. I don't need you to worry about any library files. I'm not using any, at least not now.

I'm looking to design a cooling fan duct for my Wanhao Duplicator i3 Plus 3D printer. I want something similar to what's described in the provided documentation, but I want to be able to easily customize it. I need two main modules: a simpler one like the original cooler, and a more advanced one with a cooling ring.

Here's what I need for the design, specifically:

**Core Functionality (Both Modules):**

*   **Base Shape:** The base of both designs needs to have a roughly rectangular shape with a curved front, like a "cover". The overall dimensions should be customizable, but initially, the base "cover" should be about 41mm wide, 44mm deep, and 25mm high. The front curve should be less than 1/2 of the height.
*   **Mounting:** The cooler needs four mounting points for M3 screws. These should be located symmetrically, approximately near the front left, front right, back left and back right corners of the base, with offsets as described in the sample code. The mounting points should have a nut block integrated for capturing the nut or, ideally, a threaded hole.
*   **Fan Duct:** A rectangular duct should extend from the base, leading air towards the hotend. For the simple cooler, this duct should be fairly straightforward; for the advanced cooler, it'll connect to the cooling ring.
*   **Material Removal:** I need to be able to cut out the inside of the base and duct to create a hollow, airflow channel. I need to use a boolean difference operation.
*   **Screw Mounts to Gantry:** I also need two cylindrical holes that can be used to mount the fan to the print head gantry. These holes should be positioned so that they do not collide with the fan screws. The holes should be suitable for M3 screws and nuts or, again, be threaded.

**"SimpleCooler" Module:**

*   This should be a more basic design, resembling the original cooler. It should have a simple rectangular duct extending from the base.
*   The duct opening should be slightly smaller than the base opening.

**"CoolingDuct" Module:**

*   **Cooling Ring:** This module should include a circular cooling ring that surrounds the hotend. This ring should be hollow to allow airflow. I need to be able to customize the angle of the ring, with 0 degrees meaning no ring and 360 degrees creating a full ring. I should be able to set this to 270 as a starting point.
*   **Ring Tilt:** The ring should also be able to tilt slightly to compensate for a bent mounting arm, within a range of +/- 10 degrees from the horizontal.
*   **Connection to Base:** The cooling ring should connect to the rectangular duct from the base. This should be a smooth transition.
*   **Internal Hollow:** I need to hollow out both the duct to the ring and the ring itself.

**Customization Parameters:**

*   `angle`: Angle of the cooling ring in degrees (0-360), applicable only to the CoolingDuct module.
*   `tilt`: Tilt angle of the cooling ring in degrees (-10 to 10), applicable only to the CoolingDuct module.
*   Base Dimensions (x, y, z) should be adjustable.
*   Duct Dimensions (width, depth, radius) should be adjustable.
*   Hole diameter for screws should be adjustable.
*   `fast`: A boolean flag to use either faster cylinder approximations for the screw holes or use actual threaded models.

**Libraries:**

*   I need the `metric_thread` function from the `threads.scad` library (or something equivalent) in order to generate threads for the screw holes.

**Other Notes:**

*   The base of the cooling fan duct should be roughly at z=0.
*   I would like to use the `hull()` function to create smooth transitions between the different parts.
*   Use boolean `difference()` and `union()` operations to combine and subtract the shapes.
*  Please make the code as readable as possible.
*  Please use meaningful names for variables.

Can you provide me with the SCAD code to generate these two modules and a way to switch between them with a simple variable?

I want to design a customizable fidget spinner, similar to the "What-the-Hex" design, but I'd like it to be more flexible and easier to adjust. Here's what I'm thinking:

First off, I'd like a central core that fits a standard 608 bearing. That part seems pretty standard.

For the "arms" or rays, I'd like to be able to choose how many I want – probably between 2 and 6. Also, each arm can have multiple weights, like in the original design. So, I need a parameter to choose how many weights are on each arm; I'd like to be able to choose from 1 to 4.

The weights themselves should be configurable. I'd like to be able to select from a list of options, including: a 608 bearing, 5/16", 3/8", and 1/2" hex nuts, M8, M10, and M12 hex nuts (with both the 16mm/18mm and the 17mm/19mm size options for M10 and M12), M4 square nuts, and 5/16", 3/8", 1/2", and 5/8" ball bearings. I think if we used a list or a dropdown menu, that would make it easy.

I'd also like a way to adjust the amount of "extra" length between the arm and the weight, like the `extra` variable in the original code. It should be a parameter so it is easy to control.

Finally, a big thing: I'd really like to add a small radius to all the corners. The code mentioned a `radius` variable that was causing timeouts. I want to be able to set that radius.

It seems like a minkowski operation was used to create that rounded look. I think using a `minkowski` operation with a sphere is a good way to accomplish this, so we should use that. I think that the `hfcylinder` module from the given code could still be useful for our purposes. Also, a version of the `fcylinder` function from the provided code would be a good starting point for the overall base.

I think the core ideas from the original code are good, but we need to do the corner radius right and make everything a bit more parameter-driven and straightforward. I'm hoping this will all come together into a nice, easily-customized spinner design. The original code used the standard OpenSCAD libraries; there's no need to use anything else at this time.

I'd like to create a customizable cocktail stirrer using OpenSCAD. I've got a basic design idea in mind, but I'd like the parameters to be more flexible and the design to be a bit more polished.

Here’s what I’m thinking:

The stirrer should have a long, rectangular stick for stirring.  I want to be able to adjust the length of the stick, its width, and its thickness.

At the top of the stick, there should be a decorative element, a disk that can be twisted. I want to control the diameter, the number of sides, and the amount of twist of that disk. Also, I should be able to choose if I want a completely flat disk or one with a slight vertical "thickness".

I also want to be able to add text to the stirrer, kind of like a name or an event. I need parameters for the text itself (the string), the size of the text, its font, and its height (how much it extrudes). It should be centered above the disk element.

For the core features of the stirrer, I'd like the stick to have configurable length, width, and thickness.  The decorative top piece should have a configurable diameter, number of sides, twist, and height/thickness if desired. Finally the text parameters should be: text string, font, font size and extrusion height.

I want to make sure that all of these parameters can be easily adjusted in OpenSCAD, and that the whole thing is created in a way that is relatively easy to 3D print. I'm imagining this all to be generated from a single .scad file, as it's a pretty simple design overall.

I'm looking to create a parametric spinner design that can accommodate different bearing sizes and allow for adjustments to thickness and smoothness. I've been experimenting with triangular shapes but I'm open to other ideas too.

I want the core to be a difference between a smoothed triangular prism and a set of holes for the central bearing and optional outer bearings. I want to be able to define:
* **Bearing Model:** Use a lookup table to define inner diameter, outer diameter, and height based on a bearing model number (e.g. 608, 625, etc). It should have a default to 8x22x7 if nothing is specified. This should be in its own `bearingDimensions` function. I need to be able to add/modify the list, so make sure it's easy to do that. I've been using the following table for reference (but a different list is fine):
```

```
* **Thickness (t):** The thickness of the material around the outer edge of the bearing, should be a value like `3`.
* **Hole Tolerance (o):**  A small tolerance value (e.g., 0.1) to ensure the bearing fits in the hole.
* **Smoothness (dOx, dOz):** Two parameters that control the smoothness of the design (dOx and dOz). dOx affects the smoothness in the XY plane, and dOz affects the smoothness in the Z direction. Make them defaults of 1 and 20, respectively.

The main body should be created using a `minkowski` operation. Start with a cylinder for the base triangular shape, add a smaller cylinder to smooth the sides, and use a sphere to round the edges. The triangle base should be scaled and rotated based on dOx, dOz, and bearing size.

I want to include the central bearing hole as well as three outer bearing holes placed in a triangular pattern, and some smaller cylindrical cutouts to blend them in a little. These cutouts should be a `cylinder` with a `split(h, o)` operation and `antitoroid(d+o,o)` as a sort of blended cap.

I'd also like to have a `toroid(d,h)` module for general use, and that `antitoroid(d,h,o)` that is a `difference` between a `cylinder` and the `toroid`.

Finally, there's a module called `cyl(d,h,o)` which combines a cylinder with the split antitoroids as caps.

I am *not* looking for a specific look, but I want something functional that demonstrates this approach. Feel free to use whatever modules, functions, and variables that you think make the most sense - just make sure they're all parametrically defined. Let me know if you have any questions!

Hey, I'm looking to design a clock face, and I'd like it to be parametric so I can easily adjust things. The basic idea is a disc with the first 12 elements of the periodic table arranged around the edge like numbers on a clock. The center will have a stylized atom graphic. Also, there needs to be a hole in the center for mounting to the clock mechanism.

Here are the details:

*   **Overall Shape:** It's a flat disc.
*   **Elements:** The first 12 elements (H, He, Li, Be, B, C, N, O, F, Ne, Na, Mg) should be positioned around the disc like hour markers.
*   **Text:** The element symbols should be in a font called "Harlow Solid Italic". Make sure the font is centered appropriately.
*   **Atom Graphic:** There's a central design with 3 orbits around the center. They should be a specific size smaller then the main disc and the center should have a small hole in it.
*   **Hole:** A central hole for mounting to a clock mechanism.
*   **Parameters:** I'd like these parameters to be easily adjustable:
    *   `hole_diameter`: Diameter of the center mounting hole.
    *   `r`: Radius of the main disc.

I want to be able to easily change the diameter of the center hole and the radius of the face.

The general look should match what is described in the provided SCAD file.

I'm not looking for any libraries to be used, just plain OpenSCAD. Thanks!

                    text(str(elemente[11-i]), font = "Harlow Solid Italic", valign = "center", halign = "center", size = 18);

Hi, I'm looking to create a customizable cross and base design with text on the base, and I'd like to use OpenSCAD to make it parametric. I'm thinking something along the lines of the design I saw here:

[Link to image or example if available]

Basically, I want a cross that sits on top of a base, and I'd like to be able to easily customize the dimensions of both, as well as the text on the base. Here are some specifics:

**General Parameters:**

*   I need a general "tolerance" setting (in mm, but expressed as mm/100) to help adjust for printing inaccuracies when generating the base cutout, adjustable from 1 to 100 (integer, representing mm/100).
*   I want a simple selection for what gets displayed - either the cross by itself, the base by itself, both combined, or the combined model, but with the cross rotated into its final orientation for display. This can just be an integer selection: 0 for cross, 1 for base, 2 for both, and 3 for a display version of both
*   A "resolution" parameter (integer) that controls the fineness of the curves, maybe something from 15-150 and increments of 15 should be fine.

**Cross Parameters:**

*   I'd like to be able to specify the total height of the cross in millimeters. Let's start with an adjustable range of 15-150 in increments of 5.
*   The width of the cross (the horizontal part) should be a percentage of the cross height, something like 40-75 percent, in 5% increments.
*   Similarly, the depth of the cross should be a percentage of the cross width, maybe 10-25 percent with increments of 5%.
*   I'll need to pick a color for the cross as well, it doesn't need to be parameterized but a good default would be "SaddleBrown".
*   I want to be able to offset the cross from the base wall, a small value in mm should work (0-50, in increments of 1).

**Base Parameters:**

*   The base width should be a percentage of the cross width, let's say 50-250% with increments of 10%.
*   I'd like to have an adjustable top angle on the base, something from 0-10 degrees with increments of 1 degree. Let's use 5 degrees for a default.
*   A default color for the base would be great, something like "DarkKhaki".

**Text Parameters:**

*   I'll need an offset for the top of the text to start, maybe between 5 and 70mm, in increments of 1.
*   I'll also want spacing between the lines of text, 0-40 mm in 1mm steps.
*   Let's make a default color, maybe "MediumSlateBlue"
*   I'd like a font selection to pick my font, and I'd like to specify the font size (3-12 increments of 1). I'm thinking "Arial Rounded MT Bold" as a default for the font.

**Message Text:**

*   I need an array or list of string variables to enter my message. I'm thinking 10 lines should be plenty.

Could you generate an OpenSCAD file or files for me based on these parameters? I'm not looking for any libraries like MCAD or BOSL, just standard OpenSCAD modules.
