I'd like to design a customizable two-ended measuring spoon, similar to the one described in the provided code, but I need it generated from scratch. I want to be able to set the volume for each end, choosing from units like milliliters, cubic inches, fluid ounces (both imperial and US), tablespoons (UK and US), teaspoons (UK and US), and also grams of coffee, sugar, and salt. It should have different spoon shapes available (flat, conical, cylindrical short, cylindrical long, and spherical).

I need to be able to set the thickness of the walls and handle, and the handle length and width, as well as the size of a hanging hole at the end and its distance from the second spoon. It should also have an option to add a text label, specifying the font (I'd like to be able to use fonts like Orbitron, Letters, Knewave, BlackRose, and Braille), height, and thickness of the label.

I also need to have an option to make a cross-cut for easier printing, and to have a reference volume displayed for testing, and the ability to adjust volume to compensate for variations from printing. It should use the `write/Write.scad` library from OpenSCAD.

I'm looking for a parametric design, so all of these parameters should be easily modifiable.

Also, the code seems to have some internal scaling to handle different sizes, but I'd like to start with a base design and then scale everything from the ground up with just my specified volumes.

I'd like to design a wall-mounted spice rack, and I'm hoping you can help me with the OpenSCAD code. I've got some specific ideas about how I want it to be, and I'm aiming for it to be pretty customizable.

Essentially, I envision a rack composed of multiple identical containers, each designed to hold a standard spice jar. These containers will be arranged in a row. I want the rack to be parametric, meaning I can easily adjust the dimensions of the containers and the whole structure through variables.

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

*   **`container_diameter`**: This will set the diameter of the spice jar the container is designed for. I'd like to be able to adjust this from 20mm to 80mm.
*   **`holder_height`**: This will be the height of the container, allowing for different heights of spice jars. I'd like to be able to control this from 40mm to 120mm.
*   **`back_thickness`**: The thickness of the back wall of the rack. I'd like a range for this from 1mm to 10mm.
*   **`mounting_hole_scale`**: A scaling factor for the mounting holes. This will be important since I want to use 6 x 1/2 countersunk screws, and I'd like to be able to adjust the hole size. I'd like a range for this from 0.1 to 2.
*   **`bottom_opening`**: A boolean toggle to control if the container has an opening at the bottom. This could be "yes" or "no".
*   **`front_opening`**: A boolean toggle to control if the container has an opening at the front. This could also be "yes" or "no".
*    **`mounting_holes`**: A boolean toggle for including the mounting holes. It could be "yes" or "no".
*   **`containers`**: The number of containers the rack will have. This should be configurable from 1 to 6.

I also need the mounting holes to be designed for 6 x 1/2 countersunk screws. I need the overall mounting hole pattern to be vertically spaced based on the minimum spice container height and also I need to account for screw head placement in the model.

The design should use hull() and difference() operations to create the container shape. I'd also like for the code to be efficient and easily understandable. It would be really great if I could define the screw in a separate module and have the mounting holes added as a loop.

I don't need any specific libraries for this design, so just using the basic OpenSCAD functions would be perfect.

Okay, I'm looking to design a customizable case for playing card decks, similar to "The Vault" cases I've seen online. I'd like it to be parametric so I can adjust it for different deck sizes.

Here are the key features I want:

*   **Basic Case:** The case should consist of a box with a bottom and four side walls that wrap around the deck. There will be no lid. I'll need to be able to specify the dimensions of the card deck, the wall thickness of the case, and the height of the case itself (how tall the walls are). I'm assuming the card deck dimensions include the tuck box that comes with most decks.
*   **Rounded Edges:** The corners where the walls meet should be rounded, and it should be possible to adjust this radius.
*   **Front Grip Detail:** I'd like the front of the case to have a cut-out that makes it easier to grip and slide the deck in and out. This grip should have a curved shape - I think it should be based on a quarter circle, so it's kind of like a circular cut-out where it transitions to the full height of the walls on either side, if that makes sense. The grip should also be angled back to be easy to grab onto. I need parameters to control the size of the radius and the angle of the grip.
*  **Optional Diamond Pattern:** I'd like the option to add a diamond pattern to the exterior of the case for decoration. It should be an array of small cube features that creates a grid-like diamond pattern on the side walls. I'd need to be able to enable or disable this and control the size of the diamonds. It should only affect the outside of the case; the interior should be flat.
*  **CC Tag:** There should be a customizable CC Tag on the side with the rounded grip. It should include a border, stylized chevrons, and three star shapes. It should be able to be positioned flush or centered.
*   **Units:** I will be using millimeters (mm).
* **File Organization:** Please use a modular approach, using functions and modules as much as possible.

I'm thinking the main parameters should include:

*   `DeckHeight` (mm): The height of the deck and tuck box.
*   `DeckWidth` (mm): The width of the deck and tuck box.
*   `DeckThickness` (mm): The thickness of the deck and tuck box.
*   `WallThickness` (mm): The thickness of the case walls.
*   `CornerRadius` (mm): The radius of the rounded corners.
*   `GripRadius` (mm): The radius of the quarter-circle grip.
*  `GripAngle` (degrees): The angle of the grip cut-out.
*   `DiamondPattern` (boolean): Enables/disables the diamond pattern.
*   `DiamondSize` (mm): Size of the diamonds in the pattern.
*    `TagSize` (mm): Size of the CC Tag.

I'm not planning on using any specific libraries right now, but I'll let you know if that changes. Could you provide me with the OpenSCAD code for this?

Hey, I'm looking to create a customizable, cage-like box with randomly generated internal struts. I'd like to be able to control the overall dimensions, wall thickness, density of the struts, and whether or not to include a frame around the edges. It'd be super useful if the design was parametric in OpenSCAD.

Specifically, here's what I'm imagining:

*   **Overall Box Dimensions:** I want to be able to define the height, width, and length of the box as parameters – let's call them `box_h`, `box_w`, and `box_l`, respectively.

*   **Wall Thickness:** The struts and optional frame should have a defined thickness, controlled by a parameter I'll call `wall`.

*   **Strut Density:** I need to be able to control how many struts are used within the box. A parameter `density` would work well for that. The struts should run between each of the six sides of the box, starting at random points on each side's boundary and each having a random end point in the boundary opposite to its beginning. So, for a strut that begins on the front of the box, the end of that strut will be a random point in the rear of the box.

*   **Randomness:** The starting and ending points of the struts should be pseudo-randomly generated, but I'd like to use a `seed` parameter so I can create consistent, repeatable designs and slight variations.

*   **Frame:** It would be great if I could toggle a frame on or off with a boolean parameter `useframe`. The frame should be made up of cylinders running along the edges of the box, effectively connecting them.

*   **Strut Construction:**  Each strut should be a cylinder, rendered using the `cylinder()` primitive in OpenSCAD, with its ends at the random coordinates on the sides of the box that I described above.

I think that's it! I don't have any particular library requirements, but I'm familiar with OpenSCAD so I should be able to understand the code. Let me know if you have any questions.

Okay, I'm looking for a parametric OpenSCAD design for a belt clip. I've seen a few designs out there, and I really like the idea of having a customizable image or pattern on the clip.

Here's what I need:

The clip should have a basic "U" shape to wrap around a belt, sort of like a staple that's been bent into a U. The inside of the "U" needs to fit snugly around a belt. Here are the parameters that should be adjustable:

*   **`belt_width`**: This is the width of the belt, in millimeters (the "y" dimension in the provided code).
*   **`belt_thickness`**: This is the thickness of the belt, in millimeters (the "z" dimension in the provided code).
*   **`clip_height`**: This is the height of the clip, in millimeters (the "x" dimension in the provided code).
*   **`clip_shell_thickness`**: This is the thickness of the material the clip is made of, in millimeters (a uniform wall thickness all around the U shape.)
*  **`image_scale`**: This is the height in millimeters of the raised surface design on the clip.

Now, for the image or pattern, I would like to load a 2D image and have it turned into a relief on the front of the belt clip. I'll be providing a data file (like a `*.dat` file).

*   **`image_file`**:  The path to the 2D image data file.
*   **`pixels_x`**: The horizontal resolution of the image data file (number of columns).
*   **`pixels_y`**: The vertical resolution of the image data file (number of rows). The image should scale to fit the surface area available within the clip.

Also, I'd like to include a tolerance for the inner part of the "U" to make sure it fits even with slight variations in belt thickness. Let's call it `inner_tolerance` and make it a small value like 0.15mm.

Finally, the OpenSCAD code should not require any third party libraries and should generate a single .scad file.

The clip should have the image on the front of the "U" facing outward. The bottom of the "U" shape should be on the bottom, of course.

Hey, I'd like to create a parametric snowman generator in OpenSCAD. I'm envisioning something where I can control the overall height of the snowman and the relative sizes of the three snowballs and a top hat via sliders. It would be nice to also have a slider to control the nose and the resolution of the spheres and cylinders that are used to create the snowman.

Specifically, the snowman should be built from three stacked spheres of varying diameters, with the largest on the bottom and the smallest on top. Each of these spheres should have a diameter that can be set as a ratio of the total height of the snowman. I'd like there to be three separate parameters for the bottom, middle, and top spheres' size ratios. There should be another ratio for the hat. The ratio values will be used to divide the total height of the snowman amongst the spheres and the height of the hat's cylinder, which I'll explain later.

Also, I'd like to add a top hat on top of the topmost sphere. The hat would consist of two cylinders stacked on top of each other - the bottom cylinder would have a slightly larger radius than the top cylinder and be shorter. I'd like a ratio for the height of the entire hat as well, also relative to the total height.

Additionally, it would be great if there was a parameter that controls whether or not the snowman has a nose. If yes, I'd like the nose to be a cone (cylinder with a tapered end) that protrudes outwards from the center of the top sphere, using the top sphere's diameter to determine the dimensions of the cone.

Finally, I want the user to be able to adjust the resolution of the spheres and cylinders through another parameter using a slider. I'd like to avoid using any OpenSCAD libraries. Could you generate the OpenSCAD code for me please?

Okay, I'm looking to create a book holder similar to the one described as "Joe" that I found on Thingiverse, but I need it to be fully parametric and adjustable for different book sizes and desired angles. I want to be able to easily tweak the dimensions for both the book and the support itself.

Here's what I'm thinking:

The design is essentially a stylized "man" figure that acts as a bookend. The figure has two legs (front and back), a torso/arm area, a shoulder, and a head. The book rests on the front leg and against the torso. I need the following parameters to be easily adjustable:

*   **`H`**: The height of the book (this will mostly determine the size of the figure).
*   **`s`**: The thickness of the book (used in calculating the position of the front foot/leg).
*   **`l`**: The depth or thickness of the support (how far the support extends).
*   **`a`**: The inclination angle of the book (how far back the book leans). Should be adjustable within a range, like 70-85 degrees.
*   **`t`**: The thickness of the material for the figure. (like the original, this should be adjustable, something like 0.5-5).

I also want the code to use a scale factor that is automatically determined by H.  Specifically, the `w = H/104.1212/2` calculation in the original code is important.

The figure's shape is described by a series of polygons and differences with circles. I want the code to generate these shapes based on the provided parameters using a combination of `polygon()`, `intersection()` with `difference()`, `circle()`, `translate()`, and `linear_extrude()`.

I'd like the design to also incorporate the offset library as `offset.scad`, which includes `inset()` and `inset_shell()` functions, allowing me to easily create shelled versions of the man, where you specify the thickness (`t`) of the shell. The `inset_shell` function is important and works using the difference of the original shape and an inset, scaled and translated, version of the shape to create a shell of a given thickness.

So, in summary, I need an OpenSCAD design that creates a parametric book holder in the style of "Joe", utilizing the `offset.scad` library, and controlled by parameters `H`, `s`, `l`, `a`, and `t`. I need to be able to adjust each of these parameters and see changes to the design, especially the ability to change the book height (H) and see all other dimensions adapt accordingly. The `offset.scad` library should be used, and the  `inset_shell()` and `inset()` modules from it should work as described in the code provided in the original prompt.  I'm requesting you generate a single `Joe.scad` file incorporating all of the code, including the `offset.scad` library code, so I do not have to include it.

I'm looking to create a customizable holder for my hex bits, and I'd like to use OpenSCAD to do it. The basic idea is a honeycomb-style arrangement of hexagonal cells, each designed to snugly hold a bit. I need to be able to adjust a few things:

*   **Bits per row:** This will control how many bits are in a single horizontal row.
*   **Number of rows:** This will control the number of rows stacked vertically in the honeycomb pattern.
*   **Bit diameter:** This is the diameter of the hex bits that will fit in the holder. I have a few different sizes, so it needs to be a variable.
*   **Holder height:** This determines how tall the holder is, effectively how deep each cell is.
*  **Margin thickness:** The thickness of the material surrounding each bit, which I'd like to specify as a *ratio* of the bit diameter.

Essentially, I want to specify the number of rows and bits per row and the other dimensions and the code will generate the holder. I would prefer to use as few libraries as possible. I think I can get away with no libraries.

Okay, I'm looking to create a customizable drawer system, and I'd like it to be parametric in OpenSCAD. I have a pretty good idea of what I want but need some help implementing it. I'm not very skilled with the code, so I'm hoping you can do most of the heavy lifting.

I want the design to have a few key components: a drawer box (housing) and individual drawers that fit within it. The number of drawers should be adjustable, as well as the overall dimensions of the drawers (height, depth, and width). It also needs to have a text label on each drawer. The text, the font of the text, height, and placement should all be configurable.

Here's a more specific breakdown:

**Core Features:**

*   **Drawer Box:**
    *   A box that serves as the housing for the drawers.
    *   The overall height of the box should be calculated based on the number of drawers and the drawer height plus clearances between the drawers.
    *   The depth and width should also be configurable and take into account wall thicknesses and clearances.
    *   I want the option to have hexagonal pattern cutouts in the sides.
    *   I'd like to add "mouse ears" on the box for bed adhesion.
*   **Drawers:**
    *   Individual drawers designed to fit snugly inside the drawer box.
    *   They should have adjustable height, depth, and width.
    *   Each drawer should have a customizable text label. The font for the text should be selectable from a range of options that are available in the Write.scad library, like "Letters.dxf," "BlackRose.dxf," "orbitron.dxf," "Knewave.dxf," and "braille.dxf."
    *   The text height, horizontal shift, and vertical shift should be adjustable.
    *   The text can be either embossed or raised (cutout).
    *   There should be a handle on the front of the drawer.
    *   I'd also like to incorporate a dimple stop system to keep the drawers from sliding all the way out, but also to provide a nice click when inserted into the housing.

**Parameters:**

*   `part`: A variable to determine whether to display a single drawer, or a drawer housing or some other variant.  "drawer1", "drawer2", "drawer3", "drawer4", or "drawerbox" should be the possible values.
*   `NUM_DRAWERS`: The number of drawers in the box.
*   `DRAWER_HEIGHT`: The height of each drawer.
*   `DRAWER_DEPTH`: The depth of each drawer.
*   `DRAWER_WIDTH`: The width of each drawer.
*   `MESSAGE`: The text label for the drawer.
*   `TEXT_FONT`: The font for the text label (using the "write/\[font name].dxf" format). This should be a dropdown menu with the available font options.
*   `TEXT_HEIGHT`: The height of the text label.
*   `TEXT_SHIFT_RIGHT`: Adjust the horizontal position of the text label.
*   `TEXT_SHIFT_UP`: Adjust the vertical position of the text label.
*   `EMBOSSED`:  A "yes" or "no" option as to whether to emboss or raise the text.
*   `india`: This should be a parameter related to hex pattern hole size and I will leave it up to the implementation.  I believe it is the diameter of the inscribed circle of the hexagon.
*   `spacing`: This should be a parameter related to the hex pattern, and should define the amount of space between hexagon holes.
*   `HANDLE_SIZE`: The size of the handle.
*   `DRAWER_CORNER_RAD`: The corner radius for the drawers.
*   `CLEARANCE`: The clearance between drawers and the drawer box.
*   `WALL_THICK`: The thickness of the walls.
*   `FLOOR_THICK`: The thickness of the floor of the drawers.
*   `FILLETS`:  A yes or no option to determine whether to have rounded fillets.

**Specifics about the dimple stops:**

*   I'd like the dimples to be offset so that they don't interfere with dividers in multi-sectioned drawers. There should be dimples on both sides, front and back, and on both top and bottom of drawer.

**Additional Notes:**

*   I'm using the `Write.scad` library for text rendering. You'll need to make sure that's included in the design.
*   I want the design to be clean and easy to modify.
*   I'm fine with a single file that has all of the components in it.

I think that should cover everything. Let me know if you need any additional details or clarification. I am looking forward to seeing your implementation.

Hey, I'm trying to design a stud finder and I have a basic idea, but I need help making it parametric and more robust.  I was playing around with OpenSCAD but I'm pretty new to it, so I'm hoping you can help me generate the files.

Basically, I want a rectangular box with two cylindrical handles on the sides, a cylinder that's partially cut out from the front, and space for two magnets on the front.  It should also include a simple design on the front, like my attempt at the "GS" logo.

Here are the dimensions I was experimenting with:

*   **Overall Box:** 18mm wide, 25mm deep, and 15mm tall.
*   **Handles:** Cylinders with a radius of 7.5mm and a height of 17mm, placed on each side, starting from the bottom.
*   **Front Cylinder:**  A cylinder that's hollowed out from the front, 18mm diameter and 15mm tall
*   **Magnet Holes:** Two cylindrical holes for magnets, each 12mm in diameter and 6mm deep.  They should have a smaller diameter hollowed out at the bottom with a diameter of 3 mm and a depth of 3 mm, so the magnet sits flush.  I have 12mm x 6mm magnets and they sit on the inside face, not through the face.  The first magnet hole is near the base, and the second magnet hole is near the top on the front face.

*   **GS Logo:** 15mm wide, 30mm tall, 2mm deep, located centered at the front. I'm not sure how to add things like this that are complicated.

I'm planning on using magnets from [http://www.magnets365.com/10pcs-x-strong-round-12mm-x-6mm-magnets-disc-rare-earth-neodymium-n35.html](http://www.magnets365.com/10pcs-x-strong-round-12mm-x-6mm-magnets-disc-rare-earth-neodymium-n35.html) so if the hole could be a bit bigger that would be great. I will be 3D printing the stud finder.

Could you create a parametric OpenSCAD file that allows me to easily change all of these dimensions (box size, handle size, magnet dimensions, etc.)?  I think that would be really useful. Also, I'd like to make the logo into its own module in case I want to add or remove it easily. It might be helpful to use the `difference()` module and `translate()` and `rotate()` to make things easier. Finally, can you add comments to the file so I can learn? Thanks!

I'm looking to generate some auger designs, similar to what you'd see in a drill or an Archimedes screw. I've got some specific parameters I need to be able to adjust, and I'd like to have the option to cut the auger in half lengthwise for easier printing.

Here's the breakdown:

*   **Overall Length:** I need to be able to specify the total length of the auger.

*   **Number of Rotations:**  I need to set how many full rotations the thread makes. This is crucial, as I will want to control the pitch of the helix and also, if I use a length, I can convert from a thread-per-inch type measurement.

*   **Outer Diameter:**  I need a parameter to set the outer diameter of the auger.

*   **Inner Diameter:** I need a parameter to set the inner diameter of the auger. This should effectively set the core diameter.

*   **Auger Thickness:** I need to be able to define how thick the "paddles" of the auger are. This is important to be able to produce ACME-style screw threads.

*   **Inner Shaft Option:** I need a boolean parameter to specify whether there is a solid shaft at the inner diameter or just a hole.

*   **Outer Shaft Option:** I need a parameter to specify the thickness of an outer shaft. A value of 0 would disable the outer shaft, while any other value would specify the thickness beyond the outer diameter. This is useful for Archimedes screw pump type applications.

*   **Cut in Half Option:** A boolean parameter to cut the auger in half lengthwise, for easier printing.

It would be great if the design used a smooth helix instead of the stair-stepped version that you might get with a naive rotational extrude. Also, include the ability to define the number of segments/slices in the helix - the more the better for a smooth spiral. Let's say there will be 500 slices by default.

Could you generate an OpenSCAD file or files for this design? I'm not sure if any specific libraries are needed here, but please let me know if you choose to use any.

I want the holder to be a circular base with slots around the perimeter to hold business cards.  I'd like to be able to specify:

*   The number of cards it can hold
*   The thickness of the card slots (to fit different card stock)
*   The dimensions of the cards (width and height), although these are mainly for preview purposes
*   How far the card sits from the inner edge of the base (as a percentage)
*   The tilt of the card within the slot
*   The lean angle of the card relative to the tangent of the circle
*   The height of the card slot itself
*   The radius of the base circle
*   The overall height of the base
*   The ring thickness (as a percentage of the height)

I'd also like a toggle to show the card preview in the design itself.

Ideally, the design would use a `difference()` operation to carve out the slots in a cylinder.

So, to summarize, I would need parameters for the following: `number_of_cards`, `card_thickness`, `card_width`, `card_height`, `card_position`, `tilt`, `lean`, `slot_height`, `base_radius`, `base_height`, `base_ratio`, and a `card_preview` option.  I'm thinking a simple `Show` / `Hide` toggle for the card preview.

I'm hoping the generated OpenSCAD code won't be too difficult, but let me know if anything is unclear!

I'm looking to create a customizable platform for my shower niche that will help bottles and cans dry properly and hopefully avoid rust and mold. I'd like a design that can be easily adjusted to fit different niche sizes.

Specifically, the platform should be a rectangular shape with rounded corners. It should have a raised border around the perimeter, and a support running down the middle lengthwise. The top surface should have a mesh-like pattern to allow for drainage and air circulation, and I'd like weep holes across the bottom that go through the side of the platform for drainage.

Here are some parameters I'd like to be able to control:

*   **Width:** The width of the platform.
*   **Length:** The length of the platform.
*   **Height:** The overall height/thickness of the platform.
*   **Corner_Radius:** The radius of the rounded corners.
*   **Border_Thickness:** The thickness of the raised border.
*   **Mesh_Width:** The width of the mesh slats.
*   **Mesh_Thickness:** The thickness of the mesh slats.
*   **Weep_Holes:** The number of weep holes.

I'd also like to use the `MCAD` library, specifically for the `roundcube` module (if appropriate).

Could you help me generate the OpenSCAD files for this? I'd really appreciate it!

I need a parametric design for a reel holder, specifically for Super 8 film reels or similar, and it needs to be customizable for reels of varying widths. The holder should consist of two main parts: a base/rod with a flange and a cap that locks onto the rod.

Here are the details:

**Overall Structure:**

*   The holder needs to be designed to fit onto a bolt or axle, so there should be a central hole through the entire assembly.
*   The rod part will have a flange at one end and a series of fins around its circumference and also castellations at the far end for the cap to lock onto.
*   The cap should have matching castellations to lock onto the rod, with a recess for a spring and bolt head.
*   The design should aim for minimal support during 3D printing.

**Parameters:**

*   **`SpoolW`**: The width of the reel being held, used to set length of the main rod.
*   **`AxleD`**: Diameter of the axle hole through the holder. (add an allowance for print accuracy in the code)
*   **`AxleContactL`**: Length of the axle hole at each end that contacts the axle, the middle part of the hole will have clearance to allow free rotation.
*   **`AxleClearance`**: Radial clearance around the axle hole in the middle section.
*   **`FlangeOD`**: Outer diameter of the flange.
*   **`FlangeEdgeT`**: Thickness of the straight part of the flange.
*   **`FlangeBevelT`**: Thickness of the bevelled part of the flange.
*    **`RodR`**: Radius of the inner rod where the reel sits.
*   **`CastleR`**: Radius of the castellations for locking the cap.
*   **`FinW`**: Width of the fins around the rod.
*   **`FinT`**: Length of the fins around the rod.
*   **`FinExtraL`**: Extra length the fins extend beyond the spool width, if any.
*   **`CapL`**: Length of the cap, including the recess.
*   **`CapRecessD`**: Diameter of the recess in the cap for the spring and bolt head.
*   **`CapRecessH`**: Depth of the recess in the cap.
*   **`CapBevel`**: bevelled edge at top of the cap.
*   **`CapSpringL`**: Length of the spring used with the cap (mostly used to calculate the bolt length), this should be at least 3*`CastleR`.

**Modules/Functions:**

*   The code needs to have a `cubec` module, `TZ` module, `Castle` module, `FinRod` module, and a `Cap` module, as seen in the original code, these can be re-created or copied directly if it's easier, but if you can think of better way to represent the design, please feel free to improve on the modules.
*   The design should be able to create an assembly of both cap and base in the same position, or an exploded view of the parts, or an exploded view with a cutaway, and a view of parts ready to print. There will be a "View" variable to set that.
*   There should be a "Show" variable that will show all parts, just the rod, or just the cap.

**Additional Notes:**

*   The design should minimize the need for support material during printing.
*  The design should echo the length of the bolt needed for the design.
*   I'd like to keep the `$fn` value at 50.

I think that's all the important stuff. Let me know if I've missed anything or if you need more clarification.

Hey, I've got this idea for a charm, and I'd like to get a parametric OpenSCAD file (or set of files, whatever works best!) to make it.

Basically, I want a small cube with a different image embossed on each of the four sides, and a hole through the center so I can put it on a charm bracelet. I saw this design online that uses the `surface()` function with pre-generated .dat files, and I like that. I'm providing a reference OpenSCAD file for you, to better understand the idea.

Here's the gist of what I need, with some specifics:

**Images:** I'll be creating the images as 40x40 pixel greyscale images, and using the Makerbot image converter to get the .dat files. I expect to be able to specify 4 different .dat files, one for each side. The design should automatically stretch each image to fit on the appropriate side. I need to be able to change which images are used for each side.

**Dimensions:**

*   **Depth of the embossed images:**  I want to be able to control how deep the images are embossed, as a parameter.
*   **Cube Size:** I want to set the length of one side of the cube.
*  **Image Size:** I need to be able to set the size of the image on the cube faces, in millimeters.
*   **Charm hole diameter:** I need to control the diameter of the hole for the charm bracelet.  I think 6mm is a good starting point but it needs to be adjustable.

The reference file does some rotations to get the images on the correct sides, and I need that to happen in the new file(s) too.  Also, to make sure the image subtraction works correctly, the reference file inverts the colors, so I would like that to be part of the instruction as well.

I'm not too familiar with all the OpenSCAD libraries, but it looks like this will need the `surface()` function, so I believe that's a built-in function, and I don't think I need anything else. Let me know if that is inaccurate.

Thanks!

/*To get this to work offline, any image must be converted to a .dat file using the tool at http://customizer.makerbot.com/image_surface. That will output an array of values from 0-1 corresponding to the greyscale values 0-255 of the image. Inverting the colors of the image will ensure that the recessed image gets subracted from other objects properly. Copy the arry to a text file. IMPORTANT: be sure that your file is actually a dat file and not e.g. foo.dat.txt. Some operating systems (like Windows 7 by default) hide the actual extension. Once the dat files are in the same directory as the .scad file, and are named properly the surface() function should work.

The way I prepared my image files was to:
	1	Import the image into gimp.
	2	Crop the image as tightly as possible
	3	Right click on the image: Image>Scale Image
	4	With the aspect ratio locked, change the Higher of the width and height to 100 pixels.
	5	Right click on the image: Image>Canvas Size
	6	With the aspect ratio UNlocked, change the Lower of the width and height to 100 pixels. Click "Center". Click "Resize".
	7	Right click on the image: Colors>Brightness-Contrast
	8	Increase the contrast to remove the effects of the resize, and get sharper edges.
	9	Export the file to jpg/gif/bmp/png (it doesnt really matter as long as the customizer tool can read the file).
	10	Open  http://customizer.makerbot.com/image_surface in a web browser.
	11	Select the file you want to convert. Click "Invert Colors".
	12	Copy the array of numbers to a text file.
	13	File>Save As. In the drop-down menu "Save as type:" select "All files". This will allow you to actually set the extenstion to ".dat". Name the file <whatever>.dat.

Your image should now create a surface() as intended. */

I'd like to create a customizable squobe, which is basically a cube with a sphere cut from the middle, then three perpendicular cylinders cut through it. I'd also like to be able to select from a few different printer build plates.

So, the main things I'd like to control are:

*   **`squobe_size`**: This determines the overall size of the squobe, which the cube and sphere are based on. I was thinking a range of 5 to 100 would work.
*   **`hole_size`**: This is the diameter of the cylinders that cut through the squobe. Also, maybe a range of 5 to 100? It should be configurable to be smaller than the squobe size so the holes stay within the squobe.
*   **`build_plate_selector`**: This selects the preset build plate from a list. The options I have in mind are:
    *   0: Replicator 2 (285 x 153 mm)
    *   1: Replicator (225 x 145 mm)
    *   2: Thingomatic (120 x 120 mm)
    *   3: Manual
*   **`build_plate_manual_x`**: If `build_plate_selector` is set to 3 (Manual), this sets the x dimension of the build plate. Should have a range from 100 to 400.
*  **`build_plate_manual_y`**: If `build_plate_selector` is set to 3, this sets the y dimension of the build plate. Range from 100 to 400.

The build plate should just be a thin cube that's slightly below the squobe, with grid lines on top of it.

Could you generate the OpenSCAD code for that? I don't think I need any extra libraries.

Hey, I'm looking for an OpenSCAD design for a tape cap, like the kind you put over a roll of tape to protect it. I want it to be parametric so I can adjust it for different sized tapes.

I need the cap to have a cylindrical body with a lip that goes inside the tape roll and a raised outer rim, so it sort of cups the end of the tape. I'd like the main parameters to be things like the tape's inner and outer diameter, the height of the cap, and the wall thickness of the plastic. I also want the inside lip part of the design to have a slightly thicker wall than the rest of the cap to give it some strength.

Additionally, I'd like to put some text on it, I'm thinking like two lines of text, one on top and one on the bottom, wrapping around the cap, and I need to control the text's height, thickness and spacing. The text should be positioned around the middle of the height of the cap, one line on the top half, and one on the bottom. I also need to specify the font, ideally something that's handled through the Write.scad library. I also want to have the ability to add some small dots, spheres really, around the edge on the outer diameter as sort of little decorative elements - I should be able to control how many there are.

I'd like to have a modular design - ideally I'd like to be able to easily switch between generating the whole cap with text and the dots, or just the text by itself, by setting a variable.

So, to summarize, I need:

*   A cylindrical cap with a lip that fits inside the tape roll.
*   Adjustable parameters for tape dimensions (inner/outer diameter, height), and wall thicknesses.
*   Two lines of text wrapping around the cylinder using the Write.scad library, with control over font, text height, thickness, and spacing.
*   Decorative spheres/dots around the outer edge, configurable by number.
*   A modular design where I can choose to render just the text or the entire cap with the text and dots.

The library I need is Write.scad. Thanks!

I need a parametric OpenSCAD design for a strap clip, kind of like an "S" shape, that can hold two straps or similar thin materials together. Think of it as two "C" shapes joined at their backs. The straps will slide into the openings at the "C" shapes. I already have a design that works, but it's not very flexible in terms of how it's configured. I'd like to be able to adjust some key parameters.

Specifically, I'd like to control the following with variables:

*   **`strap_width`**: The width of the center section of the clip, where the two "C" shapes meet. This will also be the width of the strap, or whatever other thin material, that I'll be holding together.
*   **`strap_thickness`**: The thickness of the strap or material to be held. This is the size of the opening the strap will slide into.
*   **`wall_thickness`**: The thickness of the walls of the clip itself.
*   **`height`**: The overall height of the clip.
*   **`tabs`**: A boolean option, enabled by default, to generate small tabs on the inner surface of the clip to provide some extra grip to the straps. I'd also like to be able to adjust the dimensions of the tabs. Perhaps with a few parameters: `tab_radius1`, `tab_radius2`, and `tab_height`.

I'd like the clip to be symmetrical and generated using the same base shape, just reflected across an axis. I think I could have used a module to do that in my design, but I'm not sure exactly how. It would be nice if the generated code used modules and wasn't quite so redundant.

It doesn't need to be terribly complex - just robust and flexible. I'd prefer it if the generated code was well-commented so I can understand what it is doing.

I think that covers all the key parts. Please let me know if I've missed anything or if you need further clarification. I expect this would need to use standard OpenSCAD functions, but if you think it's appropriate to utilize a library such as MCAD, BOSL, or BOSL2, feel free to do so. I'm open to that.

I'd like to design a nylon foot for some projects. I've been using the attached code, but I want something a little more flexible, and it could be a lot more elegant.

The basic idea is a sphere cut in half, creating a dome. I'd like to be able to specify the diameter of that sphere. Also, instead of a simple boolean difference with a cube, I'd like to have the option of creating a flat section at the bottom of the foot, a cylinder that can be used to mount a screw, and a counterbore for the screw head.

Here are the parameters I think would make the design as flexible as possible:
*   `diameter`: The diameter of the sphere used to create the dome, just like my current code.
*   `flat_height`: The height of the flat section at the bottom of the foot. If this is set to 0, the foot should just be a hemisphere.
*   `screw_diameter`: The diameter of the cylinder that will serve as the screw mount. If set to 0, no cylinder should be included.
*   `screw_height`: The height of the screw mount cylinder.
*  `counterbore_diameter`: The diameter of the counterbore for the screw head. If set to 0, no counterbore should be included.
*  `counterbore_depth`: The depth of the counterbore.

I'd also like to have the option of creating multiple of these at once, with a specified distance between them in both the x and y direction. If this isn't easily done, that's not a huge deal, though. I think I'd prefer to keep the single foot centered at the origin rather than the array, which I would like to be arranged around the origin.

Could you create an OpenSCAD file that would handle all of this? I'd like to use the BOSL2 library if possible.

Nylon_Foot.scad:

  sphere(d=Diameter, $fn=100);
  // Move
  translate(v=[0,0,-(Diameter/2)]) {
    //The cube for cutting
    cube(size = Diameter, center = true);
   }
}

Hey, I need a parametric spacer for a ZMR 250 quadcopter frame, something similar to the one I've made before, but I want it to be fully adjustable. I've attached my old code as a starting point, so you can see the basic shape and dimensions. Basically, it’s a rectangular block with two holes for mounting screws and a cutout for another part to fit in and also a central cylindrical hole.

I need to be able to adjust the following:

*   **Overall Height:** This should control the height of the entire block.
*   **Block Dimensions:** The x and y dimensions of the main rectangular block need to be parametric.
*   **Screw Hole Diameter:**  The diameter of the two screw holes needs to be adjustable.
*   **Screw Hole Spacing:** The distance between the centers of the two screw holes needs to be adjustable.
*   **Cutout Height & Width:** The dimensions of the rectangular cutout need to be adjustable.
*   **Cutout Position:** The position of the rectangular cutout along the x, y, and z axes should be adjustable, relative to the origin.
*   **Cylinder Diameter:** The diameter of the central hole should be adjustable.
*  **Cylinder Y-Position:** The position of the central hole along the y-axis should be adjustable.
*   **Z cut cylinder radius**: The radius of the Z cut cylinder should be adjustable.
* **Z cut cylinder position**: The position of the Z cut cylinder along the x and y axes should be adjustable.
* **Z cut cylinder height**: The total height of the Z cut cylinder should be adjustable.

I'd like to keep the same general shape as my example code, but the goal is to make everything configurable, including the number of facets on the cylindrical features (but maybe default to a high enough number to appear round). I think this would be best created using `difference()`, `cube()`, and `cylinder()` primitives, if that is possible. Please be sure that all parts are created via OpenSCAD primitives or modules from standard OpenSCAD libraries. I'm trying to keep it simple without using external libraries.
