Hi, I'm looking for help designing a bottle opener in OpenSCAD. I have a version that works but it's kind of clunky and I'd like something more streamlined, parametric, and easier to customize. I'd like to specify key parameters and have the model generated from that.

The basic shape should be a curved handle with a circular opening at one end for the bottle cap and a lever for the cap using a 1 Euro cent coin. It should also allow for optional text on the surface for personalization.

Here’s what I have in mind:

**Overall Shape:**

*   The main body will be a curved shape, essentially a section of a ring, but with a flattened profile on top and bottom, not just a circle.
*   The overall length should be controlled by an outer radius parameter and an angle parameter defining the arc.
*   The handle will be thick to hold. I want a parameter to control handle width.

**Cap Opening:**

*   At the end of the curved handle, create a standard bottle cap opening. This should be controlled by a radius parameter for the opening and a thickness parameter.
*   The main part of this opening will be made from intersecting two arcs, and then cutting away the space between them.
*   A small part of the opening should remain on the bottom to be used to get leverage for the cap.

**Coin Lever:**

*   A pocket must be made for a 1 Euro cent coin (17mm diameter, 2.1mm thickness).
*   The coin pocket should be positioned near the cap opening to act as a lever. It should have some extra height to provide more leverage.
*   A partial cylinder will be needed to secure the coin.

**Handle:**

*   The handle profile should be rounded on the top and bottom to make it easier to hold.

**Text:**

*   I'd like the option to add text, with each line being configurable separately (i.e. string and size for both). The text should be embossed onto the surface of the main body.

**Other:**
*   A brim should be an optional add for printing with settings.

**Parameters I need to control:**

*   `outer_radius`: The radius of the main curved body (e.g., 300).
*   `arc_angle`: The angle of the arc of the curved body (e.g., 24 degrees).
*   `handle_width`: The width of the handle profile (e.g., 3).
*   `handle_height`: The height of the handle (e.g., 20).
*   `cap_opening_radius`: The radius of the cap opening (e.g., 25).
*   `cap_opening_thickness`: The thickness of the cap opening, same as handle width.
*    `coin_diameter`: Diameter of the coin recess (17).
*    `coin_height`: Height of the coin recess (2.1).
*   `text1_string`: First line of text (e.g., "info@dg-cybersicherheit.de").
*   `text1_size`: Size of the first line of text (e.g., 7).
*   `text2_string`: Second line of text (e.g., "www.cyberscan.io").
*   `text2_size`: Size of the second line of text (e.g., 7).
*   `include_text`: Boolean to include text (0 or 1).
*    `include_brim`: Boolean to include a brim (0 or 1).

Could you please generate the OpenSCAD code for this? I don't need separate modules for each parameter, the whole thing should be controllable by a single module or top level file. I don't require any specific libraries, just standard OpenSCAD. Thanks!

Hey, I'm looking to design an earphone wrap for USB-C headphones, and it also needs to support a TRRS (3.5mm audio) plug. I've seen some existing designs that do parts of this, but nothing that handles both.

Basically, I need a central part where you can wind your headphone cord around. On the sides of this central body there should be cutouts or slots to hold the earbuds themselves and one end should have a socket for a USB-C plug. Additionally, there should also be a place to store a TRRS (3.5mm audio) plug, probably by making that part of the USB-C socket design. I was thinking that this plug storage might involve some sort of locking feature that prevents the plug from falling out.

I would also like this design to be parametric so I can adjust the size of the overall wrap, as well as the diameter of the earbud holders and the tolerances for the plug sockets. Could you generate a complete OpenSCAD file, or potentially multiple if it makes sense to break it down? I'm not using any external libraries, just base OpenSCAD, so no need to worry about that part.

I was looking at an existing earphone wrap design by Brian Khuu that's available on Thingiverse which was inspired by 80am33's "iPhone 7 Earphone Wrap," but it lacks the TRRS support that I need, and could use a more adaptable design. I liked the idea of having the earphone storage on the edges, and how it made use of cuts to hold the wrapped cable.

I'd like to create some custom buttons for my Pocket Operator, similar to the design in the `PO_ButtonGen01.scad` file I found. I need a design that allows for the following:

1.  **Customizable Characters:** I want to be able to specify which characters or symbols appear on the buttons. I’d like to use text, but also some unicode symbols.
2.  **Multiple Buttons:**  The design should automatically create multiple buttons based on the input characters. If I input "abc", it would generate three buttons. If I input more than 4, it should arrange them in a grid. I need to be able to control the spacing between each of these buttons.
3.  **Emboss or Deboss:** I need to be able to select whether the characters are raised (embossed) or indented (debossed) on the button.
4. **Button Dimensions:** I should be able to specify the overall height, the radius, and the fillet radius of the button.
5. **Font Options:** I need to have control over the font face and style used for the characters, and the size of the characters and their offset to adjust position.
6. **Simple Shape:** The basic button shape is cylindrical with a rounded top edge, with a cylindrical post or 'cross' below the main surface.
7. **No libraries:** I don't want to depend on any external libraries.

So, could you generate a parametric OpenSCAD file (or files if that makes it easier) to accomplish this? I'd also like to set the `font_face` to "Segoe UI", the `font_style` to "Bold", and the initial `characters` to be "abc". The initial button dimensions can be `button_height = 6.0`, `button_radius = 3.5`, and `button_fillet_radius = 0.6`. The initial `button_spacing` should be 15, `char_size` should be 4.0, and `profile_depth` to 0.6. The initial `style` should be "emboss". Character offsets should initially be 0.

I'd like to design a customizable mounting system for a printer chassis, specifically a t-nut and bolt setup. I need to be able to adjust the screw thread diameter and length, as well as the washer dimensions.

Here’s what I'm envisioning:

*   **T-Nut:** The t-nut should have a central threaded hole and a circular base with a slightly curved profile. I want to ensure the screw doesn’t slip when tightened, so the circular base of the t-nut needs to fit securely within the printer chassis.
*   **Bolt:**  The bolt should have a standard hex head, with a threaded portion that matches the t-nut.  I need to be able to set the thread length separately from the overall bolt length.
*   **Washer:** A simple washer, with a hole to match the bolt diameter and adjustable outer diameter and thickness.

Specifically, I need the following parameters to be customizable:

*   `longueur_vis`: The length of the threaded portion of the bolt.
*   `diametre_filetage`: The diameter of the screw thread (for both the bolt and the nut).
*   `largeur_rondelle`: The width of the washer (how much it extends beyond the bolt).
*   `epaisseur_rondelle`: The thickness of the washer.

I'd like to use the following libraries in OpenSCAD: BOLTS. I'm not sure if it has all the features I want though, so please let me know if another library would be more helpful.

Could you generate an OpenSCAD file (or files) to achieve this?

I need a parametric tube adapter designed in OpenSCAD. I've got some specific requirements for it. It'll be a simple adapter, going from one diameter to another, with optional grooves on either end.

Here's what I need to be able to control:

*   **Large Diameter Outer Diameter:** The outer diameter of the larger end of the adapter.
*   **Small Diameter Outer Diameter:** The outer diameter of the smaller end of the adapter.
*   **Wall Thickness:** The thickness of the adapter's walls.
*  **Large Diameter Length:** The length of the straight section on the larger diameter side.
*   **Small Diameter Length:** The length of the straight section on the smaller diameter side.
*   **Overall Length:** The total length of the adapter.
*   **Large Diameter Groove:** A toggle (on/off) for a groove on the large diameter end.
*   **Large Diameter Groove Width:** The width of the groove on the large diameter end.
*   **Large Diameter Groove Thickness:** The thickness (depth) of the groove on the large diameter end.
*   **Large Diameter Groove Distance:** The distance from the large diameter end to the start of the groove on the large diameter end.
*   **Small Diameter Groove:** A toggle (on/off) for a groove on the small diameter end.
*   **Small Diameter Groove Width:** The width of the groove on the small diameter end.
*   **Small Diameter Groove Thickness:** The thickness (depth) of the groove on the small diameter end.
*   **Small Diameter Groove Distance:** The distance from the small diameter end to the start of the groove on the small diameter end.

Essentially, the main body of the adapter should be a hollow, tapered cylinder. Then, if enabled, grooves are added on each side at the specified locations and dimensions. I don't need any chamfers or fillets.

I'm hoping you can provide me with a single OpenSCAD file that handles all of this. I don't need any external libraries.

Hey there, I'm looking to design a bit holder for Milwaukee Packout cases, similar to the one I found on Thingiverse but I need it to be completely parametric so I can tweak it for different bit sizes and spacing. I'd like it to have a main bin to hold a number of individual bit holders.

Here's how I envision it:

**Overall Structure:**

*   **Main Bin:** This will be a rectangular box with rounded bottom edges. It should have space for holding multiple bit holders side by side. It should have a couple of chamfers on each of the top edges of the box and on the edge of the rounded bottom.
*   **Bit Holders:** These will be long, thin pieces that fit snugly within the main bin. Each will have multiple holes to hold drill bits. I'll need to be able to easily adjust the number of holes, hole diameter, spacing between the holes, depth of the holes and the material thickness of each holder.
*   **Spring Slot:** Each bit holder will need a slot for the spring mechanism in the Packout case. This needs to have adjustable depth and width.

**Key Parameters I Need to Control:**

*   **Main Bin:**
    *   `bin_width`: overall width of the main bin
    *   `bin_length`: overall length of the main bin
    *   `bin_height`: overall height of the main bin
    *   `bin_thickness`: the material thickness of the bin walls.
    *  `chamfer_size`: how large are the edge chamfers
*   **Bit Holder:**
    *   `holder_width`: overall width of the bit holder
    *   `holder_thickness`: the material thickness of the bit holder
    *   `holder_length`: overall length of the bit holder.
    *   `bit_diameter`: diameter of the bit holes
    *   `bit_depth`: depth of the bit holes
    *   `num_bits`: number of bit holes
    *   `bit_spacing`: spacing between the centers of the bit holes
    * `spring_slot_depth`: Depth of the spring slot
    * `spring_slot_width`: width of the spring slot
    *   `holder_pivot_dia`: Diameter of the pivot shaft
    *   `holder_pivot_length`: Length that the pivot shaft extends beyond each side of the holder

**Other Considerations:**

*   The bits should sit somewhat deeply in the holes.
*   I'd like to be able to easily adjust the bit hole diameters.
*   I need to be able to adjust the number of bit holder modules that fit inside the main bin.
*   The bit holders need to have a pivot point (a cylinder) at the bottom that matches the bottom of the main bin.

It would be great if the design could be made using OpenSCAD and if it would be easily customizable. I'm not too familiar with libraries other than `MCAD`, so if you use any I'd appreciate it if you could mention what is being used.

Hey, I'm looking to generate some bee hive frame spacers, and I think I need a parametric design in OpenSCAD. I've got some basic requirements and a sketch of how they should work, but I'm not sure how to best structure the code.

Basically, the spacers will hold frames apart at a consistent distance. Here's what I need to be able to customize:

*   **`distance`**: This is the center-to-center distance between frames. Typically this will be in the range of 35-38mm, but I need to be able to set it precisely.
*   **`framesize`**: The width of the frame rest. It's better if I can make this a bit larger than the actual frame width.
*   **`frames`**: The number of frames the spacer is meant for. I need to vary this, usually between 3 and 6 frames.
*   **`Thickness`**: The thickness of the spacer.
*   **`holesize`**: The diameter of the mounting holes, and really, these should be circular holes.

I’d like the design to generate a single piece with the frame rests and mount holes.

The frame rests need to have a "U" shaped profile, with two rectangles connecting by a rounded piece. There should be a cutout going down the middle of the frame rest, and some small supports on the bottom to allow for easy placement of the frames. I'd like it to be sturdy enough to support the frames, but not so bulky that it takes a huge amount of material. The mounting holes I would like along one edge of the piece. The outer holes will be placed slightly in from the edges.

I'm hoping to get the OpenSCAD code so I can generate the .stl and print these myself. I don't need any special libraries, just the core OpenSCAD language. Can you help me with that?

Hi! I'm looking to create a customizable bracket for attaching carbon fiber rods to flat surfaces, kind of like the one I've been using, but I need it to be fully parametric and a little bit more flexible.

Here's what I have in mind. The basic idea is a flat base with mounting holes, and a stem that extends from the base at a 45-degree angle (relative to the base) to hold the end of a carbon fiber rod.

Specifically, I'd like to be able to control the following parameters:

**Base:**

*   `baseWidth`: The width of the flat base (in mm).
*   `baseLength`: The length of the flat base (in mm).
*   `baseThickness`: The thickness of the flat base (in mm).
*   `screwHoleDiameter`: The diameter of the mounting screw holes (in mm).
*   `screwHoleOffset`: The distance from the edge of the base to the center of the screw hole(s) in mm. (I think it needs to be the same for both x and y axes for ease of use).
*    `screwHoles`: The number of screw holes on each side of the base, allowing for 1 or 2 on each axis (should default to 2).

**Rod:**

*   `braceRodType`: A choice between "Square" or "Round" to determine the shape of the rod being held.
*   `braceRodWidth`: The width or diameter of the rod (in mm).
*   `braceRodHeight`: Only used for square rods, the height (in mm) of the rod (If square rod, should default to the same value as braceRodWidth).
*   `stemLength`: The length of the stem holding the rod (in mm).
*    `rodTolerance`: A value (percentage) which is added to the dimensions of the rod holder to provide tolerance and a tight fit. Defaults to 8.5%.

**Other:**

*   `shrinkPCT`: Percentage that part shrinks on printing.  Should default to 2% and should also affect the tolerance value.
*   `fudge`: A small value in mm to prevent overshoots or coincidences. Should default to 0.02.
*  `$fn`: should be configurable.
*  `res`: a value of 1 (normal) or 2 (higher) to affect the resolution of curves.

I'd also like it if the base could optionally have some small "grip" dimples/spheres around the screw holes to increase the holding power. I would like to toggle that with a boolean variable `extraGrip`, which should default to `false`. These should be on the opposite side of the base as the rod attachment.

Also, it'd be great if I could set a cleanup box which has a negative height. This would allow me to clean up any overshoots generated during development. That height should be variable, but be based on stem radius so that it auto-scales with changes to the rod. This cleanup cube can default to `true`, with the option to turn it off via a `cleanup` variable. It should default to `true`.

The mounting holes should extend through the base and the grip spheres should only be on the bottom of the base. The stem should bury itself slightly into the base (1mm is fine) to give it a little more strength. The angle should remain fixed at 45 degrees for now.

I think that covers everything! I am happy to take it from there once I have some basic scad files, and I’d like to use the standard OpenSCAD libraries (not BOSL or any others for now). Thanks!

I'd like to design a parametric case for a Pokewalker, which is a small pedometer. I'm aiming for something that's highly customizable. Here's what I have in mind:

**Core Structure & Dimensions**

*   The clipping mechanism needs to be adjustable in terms of the number of segments used for the clips, and a tolerance setting to help with printing.
*   I need to be able to decide whether or not to include an IR port and a screen cutout, so I'd like those to be optional parameters.

**Button Options**

*   I need control over how the buttons are treated. I'd like options to have the buttons exposed, completely covered with individual caps, or covered by a flat base.

**Customization Options**

*   I also want to be able to add custom modifications to the back of the case, including an avatar (a pixel-art style image), or custom text that I can specify. The scale of this modification should also be configurable.

**Specific Dimensions (Initial Values):**

*   Pokewalker Radius: 24.5
*   Pokewalker Height: 14.0
*   Clip Segments: 6
*   Clip Segment Tolerance: 1 degree
*   IR Port Radius: 10
*   IR Port Z Position: IR Port Radius / 2
*   IR Port Y Position: Pokewalker Radius + 5
*   Screen Height: 18
*   Screen Width: 26
*   Screen Y Position: 2
*   Small Button Radius: 2.8
*   Small Button Height: 1.7
*   Large Button Radius: 3.5
*   Large Button Height: 1.7
*   Small Button X Position: 10.5
*   Small Button Y Position: 13
*   Large Button Y Position: 15

**Other Requirements:**

*   I'd like to be able to render just the top half, just the bottom half, or both together using a parameter.
*   The code should use `$fn` for circle smoothing control. Default should be 96.
*   I don't have any libraries in mind, so you can suggest appropriate ones if you think they would help! I definitely want it all to be parametric, though.

It would be great if the output files were something like `pokewalker_case.scad` with the various modules and settings. Let me know if you have any questions!

I'm looking for an OpenSCAD design for a simple pencil protector. Basically, it's a sleeve that goes over the sharpened end of a pencil to keep it from poking through pockets or getting broken.

Here's what I'm thinking:

*   It should have a short, cylindrical section at the base that fits loosely over the unsharpened part of a pencil.
*   Then it should taper into a cone shape towards the tip.
*   The tip should be a rounded, mostly closed end, just enough to protect the sharp point.
*   I also need a small tab on the side of the base, sticking out to act as a roll stop.

I'd like it to be parametric so I can adjust the following things:

*   `pencild`: The diameter of the pencil (both hexagonal and round pencils), roughly 7.3 or 7.6 mm.
*   `coneh`: The length of the conical part.
*   `wall`: The general wall thickness of the protector.
*   `tipod`: The outer diameter of the tip.
*   `cylh`: The length of the short cylinder at the base
*   `cylid`: The inner diameter of the cylinder at the base.

I think that should cover the basics. I don't need anything super complex. And because it'll be 3D printed in TPU, the sizes are somewhat flexible because it will stretch. It doesn't have to be a super snug fit, but shouldn't be super loose either.

I'm using OpenSCAD so no need for any libraries unless they are very useful, and I'd like to get the code with comments. I'm expecting all code in one file unless it's a lot.

od = id+wall;
// length of short cylindrical section on the unsharpedened part of the pencil
cylh = 10;
cylid = pencild + 0.5;  // make the opening loose

// shaft
difference() {
    union(){
        cylinder(h=cylh, d = od);
        // roll prevention
        translate([-od/2,-od/2,0]) cube([od/2, od, wall]);
    }
    cylinder(h=cylh, d1=cylid, d2=id);

translate([0,0,cylh+coneh]) difference() {
    // should fix the tangent here, but it's close
    sphere(d=tipod);
    translate([0,0,tipod/2-wall-tipid/2]) sphere(d=tipid);

I need a custom cable clip designed for 3D printing, similar to the ones used on Weller desoldering stations. I'm looking for a parametric design that I can adjust for different cable sizes.

Specifically, I need the clip to hold two cables side-by-side. The design should include the following parameters:

*   **`thickness`**: The wall thickness of the clip, probably around 1 to 3 mm.
*   **`w`**: The length of the clip. I'd like to be able to set the length of the clip to between 5 to 20 mm.
*   **`dia1`**: The diameter of the first cable. This needs to be adjustable between 3 and 10 mm.
*   **`dia2`**: The diameter of the second cable, which also needs to be adjustable between 3 and 10 mm.

The clip should have a rounded, cylindrical shape for each cable opening, and an opening angle to be able to push the cables in. I think an angle of 60 degrees would work fine for that. I also need the two halves of the clip to overlap slightly, to make it manifold for printing.

I would prefer that the design is generated using a standard OpenSCAD library, like BOSL2, if possible, to maintain design consistency and utilize already available functions.

Hi, I'm looking for an OpenSCAD design for a customizable tray to hold QFP chips for shipping and storage. I want to be able to adjust the dimensions to fit different sized chips, as well as control the number of chips it can hold.

Here are the specific parameters I'd like to control:

*   **Chip Dimensions:**
    *   `SizeX`: The horizontal length of the chip body, excluding legs.
    *   `SizeY`: The vertical length of the chip body, excluding legs.
    *   `SizeZ`: The height of the chip body.
    *   `LengthLeg`: The length of the pins/legs extending from the chip body.
*   **Holder Details:**
    *   `HeightFoot`:  The height of the raised area on the base that holds the chip so the legs don't touch the tray base.
    *   `Tolerance`:  A tolerance value, which would act as a small gap added to all the box dimensions.
    *  `SizeWall`: Wall thickness of the holder
*   **Tray Layout:**
    *   `NumHor`: The number of chip holders horizontally.
    *   `NumVer`: The number of chip holders vertically.

I'd also like the holders to have a small base plate and walls that extend up past the top of the chip, and the holders need to be properly spaced, accounting for the wall thickness and tolerance. I would also like it to be parametric and easy to adjust for any QFP or similar chip package. I'd prefer if the design doesn't rely on any external libraries, so it's just pure OpenSCAD.

Could you create the OpenSCAD file for this design?

I want to create a customizable tombstone-shaped plant marker. I'd like to be able to specify the plant name that's engraved on it, the size of that text, the length of the anchor that goes into the soil, and the thickness of that anchor. The tombstone itself should have a rounded top and be a certain thickness. I also want to specify how deep the letters are engraved.

Specifically, here are the details:

*   **Plant Name:** This should be a text parameter, so I can write the name of the plant. I need to be able to pass this in. I'd like the default to be "Basil"
*   **Text Size:**  I need to be able to adjust the size of the plant name text. The default size of the plant name text should be 15.
*   **Anchor Length:**  This is the length of the stake that sticks into the ground. The default length should be 70.
*   **Anchor Thickness:**  This is the thickness of the stake. The default thickness should be 1.5.
*   **Tombstone Thickness:** The thickness of the tombstone itself. The default should be 10.
*   **Letter Thickness/Depth:**  This controls how deep the letters are engraved into the tombstone.  The default should be 1.
*  **Tombstone Shape:** The tombstone should be a rounded rectangle shape - basically a cube with a cylinder on top.
*  **Engraving:** The text "RIP" should be engraved above the plant name. The font should be "Times New Roman". This should be engraved to the letter thickness specified by the user.

I'd like this to be generated with a single OpenSCAD file that I can customize with these parameters. I'd like all of the units to be in mm. I'd like the object to be centered at the origin. Can you please generate that for me?

Okay, I'm looking to create a customizable nautilus shell-like design in OpenSCAD, and I want it to be pretty flexible. I'd like to be able to control quite a few aspects of it.

First, I'd like to choose the basic shape of the rings that make up the shell. I'm thinking of three options: a standard cylinder, a polygon with a configurable number of sides, and a sphere.

Next, I need control over the number of rings in the shell. I'd like to set this as a parameter, so it's easy to make shells with more or fewer rings.

Also, I want to make the rings elliptical. The way I see it, the first ring (at the center of the spiral) and last ring (outermost ring) would be scaled differently on the X-axis, making them elliptical, and the scaling of the rings in between would be a linear interpolation of those two scale factors.

Another thing, I'd like to stretch the whole shell in the Z-axis. A parameter that controls how much the shell is pulled in the z direction would be awesome.

I also want to control the angle used to create the shell's spiral shape. I need a parameter to multiply the default angle between rings to control how tightly the shell curls, so I can get a range of spiral types.

If I pick a polygon for the ring shape, I need a way to set the number of sides on the polygon.

And then, for those polygon rings, I’d like each ring to be able to rotate relative to the one before it. So a parameter to control the angle of that relative spin would be great.

Finally, and very importantly, I want to be able to re-orient the whole shell in 3D space. I'll need parameters that control the rotation around the X, Y, and Z axes separately. I think that's everything, but I'll let you know if I think of anything else. I am not planning to use any libraries. Can you create this for me as a parametric OpenSCAD file?

I'm looking to create a parametric OpenSCAD model for a whetstone holder, similar to the one described in the provided text, but I want it to be entirely generated from parameters, rather than importing an STL. I need to be able to specify how many whetstones the holder should accommodate, and the holder should consist of a base and multiple middle layers, similar to the way the described model uses `pt1`, `pt2`, and `pt3`.  I'd like to use a library to assist in generating a rounded cuboid, rather than using the built-in `cube` function and a lot of `hull()` operations to give it the nice rounded corners. It'd also be nice if the library supported a general chamfer operation, or something equivalent.

My whetstones are 150mm long, 50mm wide, and 18mm thick, but I would like these dimensions to be parameters in the design. I'd like the "base" to be 8mm thick below the bottom surface of the whetstone. I also want a gap of 1mm between each stone, so if I have two stones, the second stone will be placed 1mm from the right edge of the first.

The holder should have a raised rim along its length, to keep the stones from sliding off. The rim should be 8mm wide at the base of the holder and taper at 45 degrees such that it's only 3mm wide at the top, and it should be 15mm tall. The rounded corners for the body should have a radius of 5mm. The rounded corners for the inner support structure should have a radius of 3mm. For the middle layers, the space for each whetstone should be 20mm tall, and the part itself should be 10mm tall with 1mm of extra space at the top.

I'd also like the bottom of the base to have small, rounded feet on each corner, so the base is raised 3mm off the table. These feet should be 5mm radius, 2mm tall cylinders, joined to the bottom with 2mm tall rounded cylinders of the same radius.

So to summarize, I need:
*   A parametric design that can handle an arbitrary number of stones
*   Parameters for stone length, width, and thickness.
*   Parameters for base thickness, gap size, raised rim width/height/taper, the radii for all rounded corners, the middle layer height, and the height of the gap for the middle layers.
*   Feet on the corners, described by radius and height.
*   I want to use a library that does rounded cubes and chamfers.
*   The base of the box should be 8mm taller than the bottom of the stone.
*   The gap between stones should be 1mm.
*   The middle layers should be 10mm thick with 1mm of additional vertical space for the stone.
*   The space for each stone in the middle layer should be 20mm tall, with 11mm of the height belonging to the part itself.

I would prefer to use the BOSL2 library, if possible, but if another library is much better, I'm open to that as well.

I'm looking to create a customizable kitchen knife sharpener using OpenSCAD. I've got a pretty good idea of what I want based on an existing design, but I need help implementing it parametrically.

The sharpener will consist of a main body with two parallel screws or rods holding a series of washers. These washers will be the actual sharpening elements. I want to be able to adjust the following parameters:

*   **`d_screw`**: The diameter of the screws or rods holding the washers.
*   **`l_screw`**: The length of the screws, which effectively determines the width of the washer stack.
*   **`d_washers`**: The diameter of the larger washers used for sharpening.
*   **`dist_screws`**: The distance between the two screw/rod axes.
*   **`handle_len`**: The length of the handle portion of the sharpener.
*   **`handle_h`**: The thickness of the handle.
*   **`handle_r`**: The radius of the rounded corners of the handle.
*   **`spacing`**: The spacing between each washer and its cover within the body.
*    **`wt`**: The wall thickness for the washer cover.

I need the design to account for a few things specifically:

1.  The washer stacks should be offset such that the larger washers on one screw are positioned opposite smaller washers on the other, allowing a "staggered" sharpening action. I’ll be inserting smaller washers between each pair of the larger ones, so the model should accommodate that.
2.  There should be a clearance around the washers so they’re not pressed against the body itself. This clearance is controlled by the `spacing` parameter.
3.  The handle should be a rounded, ergonomic shape, as in the original file.
4.  The design should include screw holes for mounting the screws (or rods).
5. There should be a knife slot on one side.

Could you please generate the necessary OpenSCAD code for me? I don’t want to use a library; please write the functions and modules in the main file.

Hi, I'm looking for an OpenSCAD design for a wall-mounted drill holder. My drill has a conical head, so the design needs to accommodate that. I need it to be fully parametric so I can tweak it for different drills I might get in the future.

Here's what I have in mind:

*   **Main Body:** The main body should be a kind of rounded rectangular prism with a hole to hold the drill. The hole will be conical, matching the drill head.
*   **Conical Hole:** The conical hole needs to have parameters for the larger radius (at the front), the smaller radius (at the back), and the overall height of the cone.
*  **Rear Gap:** I need to be able to specify a space at the back of the holder to accommodate the body of the drill if needed.
*   **Material Thickness:** A parameter to control the thickness of the material around the drill hole, this will also control the "frame" of the holder.
*   **Optional Half-Open Design:** It'd be nice if I could define how much larger than half the width the surround is. Setting this to a large value should effectively make a "closed" holder; a smaller value would make it more like a clip, open on the front. The default, however, should be a closed surround.
*   **Mounting Holes:** I'll need mounting holes for screwing the holder to a wall. These should have parameters for the screw hole radius, the screw head radius, and the screw head depth, as well as the length of the hole.
*   **Front Mounting Hole:** A larger hole on the front, possibly to allow an appropriate tool to be inserted. This should have a defined radius.
*   **Rear Mount:** A rear mount piece should be created, with parameters for width, thickness and height as well as offset and screw hole size, and distance. There should be two on each side.
*   **Rounded Corners:** All corners and edges should be rounded using a radius parameter.
*   **Overall Dimensions:** The overall width and length are dependent on other parameters but should be easily calculated.

I think that covers it. It would be great if the generated files could use the BOSL2 library for its more advanced functions. Thanks!
