I'm looking to design a floating money box, kind of like a miniature oil rig. It's going to be a hexagonal platform supported by pylons, and the idea is that kids can save money in it, and maybe "sink" it to get the coins out later. The design is inspired by the PetroSA oil rig I saw in Mossel Bay.

Specifically, I need a hexagonal platform that has six pylons supporting it, one on each corner. Each pylon should have a cap on top that allows coins to be inserted. The design should use standard, readily available coin sizes for the slot and the overall container, but everything should be parametric so I can adjust it to different sizes if needed.

Here's a breakdown of what I need:

*   **Platform:** A hexagonal platform with a defined radius. The platform itself can be made of six rectangular segments, rather than an extrusion of a hexagon, and each one has slots for attaching the pylon caps.
*   **Pylons:** Cylindrical pylons that fit into the platform. The pylons should have a locking mechanism that mates with a slot on the cap and slot in the platform to keep them in place. These should be hollow so the money can be placed inside
*   **Pylon Caps:** These fit on top of the pylons and have a slot for inserting coins, and also a slot that allows them to lock into the pylons.
*   **Parameters:** Everything needs to be parametric, meaning I can change things like the coin diameter, coin thickness, pylon height, platform radius, and the clearances of all mating parts. It would be nice if we could also control the number of sides to the platform, to make a pentagon or octagon as well.

I'm aiming for a design that can hold around R100 worth of R2 coins (South African currency). The coin diameter is approximately 23mm, and coin thickness is approximately 2mm, but please allow for tolerances. It's important that the design is printable on a standard 3D printer.

I have provided an example file previously.

I'd like the design to use the MCAD library for any functions that can be obtained from it.

Can you generate the necessary OpenSCAD files for this project?

Hey, I'm looking to get an OpenSCAD design for a twisted key fob, kinda like the one I saw online, but I need it to be fully parametric. It should have a twisted central section, and I'd like to be able to add text on the outside surface.

Specifically:

*   **Text:** I want to be able to specify up to four lines of text, each with its own string. There should be a parameter to choose how many lines are actually shown (0 to 4). Each line should be evenly spaced around the fob, and I need an option to set an initial text rotation angle.

*   **Font:**  I'd like to be able to pick from a few common fonts, like "Liberation Sans", "Montserrat", "Open Sans", and "Oswald". Also, I need to choose from font styles like "Regular", "Bold", "Italic", and "Bold Italic". It's important that there be a parameter to make the text's length adjustable for spacing.

*   **Shape:** The twisting of the central section needs to be parameterized, including a "center twist" angle. There should be a parameter to control the surface height where the text appears, as well as the amount the text surface is twisted. I want an option to adjust the ring's "stretch" to change the shape.

*   **Advanced:** The model should use a configurable number of facets for curves. I'd like to adjust the text size, its width, and its height scaling.

*   **Hidden:**  I'd also like to have hidden parameters for fine-tuning, like adjusting text position on the x axis, text vertical z position, ring slice amount, length percentage of center slope, an overall center scale, and a parameter for if the ring is fully closed.

The overall design is an open ring with a twisted segment, where the text appears on the outer surface of this twisted area. The design looks kind of like an infinity symbol that's partially open to allow a keyring to be attached.

I'm also assuming this will be built using built-in OpenSCAD functions like `linear_extrude`, `rotate_extrude`, and `text`. I'm also going to need the design to be a standalone set of files; I don't want to depend on external libraries like MCAD or BOSL.

Okay, I'm looking to design a customizable ring that holds a coin, kind of like a wearable coin display. I've got some specific dimensions in mind, but I'd like to make it easily adjustable.

Here's what I need:

**Coin Holder:**

*   It should hold a coin that's roughly 20.88mm in diameter and 1.53mm thick.
*   The coin has a middle hole with a diameter of 4.46mm.
*   I want a raised border around both the inner and outer edges of the coin. The inner border should extend about 1mm out from the hole, and the outer border should be about 1mm in from the coin's outer edge.
* The coin should sit in a recessed area such that the top of the coin is flush with the top of the coin holder.

**Finger Ring:**

*   The ring needs to fit various finger sizes. I want to be able to adjust the finger diameter with a parameter, something like 14mm, 16mm, 18mm, 20mm, 22mm, and 24mm.
*  There should be a small tolerance for the ring size - let's say 1.5mm on the diameter.
*   The ring design itself should have a circular shape, but it should also have a flat portion that connects to the main structure.
*   The ring should also have a small offset from the center of the ring to the structure. Let's start with 0.1mm.
*   The diameter of the ring section, excluding the flat part, is approximately 4mm.
* The actual diameter of the ring circle should scale in size, but start at around 75%. The parameter should be called `RING_SCALE`

**Main Structure:**

*   This is the part that connects the coin holder to the finger ring.
*   The depth of the structure can vary in segments; start with an overall depth of about 20mm. The segments don't need to be very sophisticated, but I'm open to ideas for a cool stepped/layered kind of design. Use the following segments, with the assumption that there should be twelve height segments that are equal:
    *   Segment 1 & 2, depth 0
    *   Segment 3-5, depth of 2
    *   Segment 6 & 7, depth of 1.5
    *   Segment 8, depth of 0
    *   Segment 9 & 10, depth of 1.5
    *   Segment 11 & 12, depth of 2
*   The main structure has an offset from the circular ring section, start at 0.1mm.

**General Requirements:**

*   I'd like to be able to change the overall thickness of the main structure by a multiplier. So, if I set it to "3" it'll be three times the coin's thickness.
*   I want to have a few predefined color schemes. I'd be great if the different parts (coin middle, coin border, structure, ring) could be set to different colors within each color scheme. For this initial iteration, please include these three color schemes:
    *   "Silver" (all parts should be a silver-ish color, like "Snow", "Gainsboro", etc.)
    *   "Pink" (all parts should be pink-ish, but feel free to use different pinks)
    *   "Grey" (all parts should be a neutral grey color).
*   I'd like to have different rendering modes, so I can see the full assembled object and also just the ring for size adjustment.
*   I'm thinking a resolution of 128 for smooth curves would be good.

I know that's a lot, but I want a design that's flexible and easy to customize. It would be great if the output file contained descriptive comments to help future users. Thanks for your help!

[User]
I'm looking to create a parametric cable tie generator, similar to the one I found on Thingiverse by Jetty (thing:58776) but with some key modifications and improvements to make it more robust and easier to customize. I'm thinking of the design being modular in that it has separate functions for the different parts of the tie so that I can easily add or change features.

Here’s what I need:

**Core Functionality:**

*   **Parametric Cable Tie Length:** The primary parameter should be the overall length of the cable tie. This should include a head, a toothed tape, and a leader.
*   **Tape Width and Thickness:**  I need to be able to control both the width and thickness of the toothed tape section.
*   **Toothed Mechanism:** The tape should feature teeth that engage with a pawl in the head. I want to control the tooth pitch and the gear border thickness.
*   **Leader Design:** A tapered leader section at the end of the tape, with the ability to add small retainers to it.  I’d like to control the length of the taper, the overall leader length, the diameter of the round end of the leader, and the spacing and number of retainers.
*   **Head Design:** The head should have a cutout for the tape to pass through and a separate cutout for the pawl mechanism. I need to control the length, width, and height of the head, as well as the corner radius.

**Added Features:**

*   **Label Integration:** I want to add a rectangular label area to the side of the head, where I can easily write with a marker. This should be customizable in width, depth and thickness.
*  **Optional Screw Hole:** The user should be able to choose to add a screw hole at the end of the head. I need to be able to specify the diameter of the hole and the border surrounding it and the length of the attachment section.
*   **Release Tab:** An optional release tab for the pawl to allow for the reuse of the tie.

**Technical Details:**

*   **OpenSCAD Libraries:** Please use the `utils` library, particularly the `build_plate.scad` module for build plate customization (if possible). I want to be able to chose from different printer models and also specify a manual x/y dimension, all from the customizer.
*   **Modularity:** The code should be modular. I would like separate modules for the head, tape, leader, and pawl mechanisms to keep things clean and customizable. Also a separate module to generate the label.
*  **Clear Customization:**  All the key parameters should be easily adjustable from the Customizer.
* **Units:** I'm using mm units throughout.
*  **Comments:** Please add detailed comments to explain the purpose of code sections and design choices.
*  **Optimization:** Please optimize for 3D printing, taking into consideration layer height, nozzle diameter and manifold correction for best results. I would like to be able to adjust these settings as well.

I believe these features should cover all my needs, while also being quite flexible.

Hey, I'm looking to get an OpenSCAD design for a modular cable chain, similar to the one in the provided link, but I need it to be parametric. I want to be able to easily adjust the width of the chain and choose between having rounded or squared-off edges.

Specifically, the design should consist of a repeating link. Each link has a base with a central hole for the cable to pass through, a middle section that provides flexibility and an end section that allows the links to snap together.

The base should have a flat bottom with some side walls, and it should have the ability to choose between rounded and squared off edges on the top of the sides. The mid section connects the ends of the base and allows the whole thing to bend. The end of the link has a snap which connects to the next link.

I need the following parameters to be easily changeable:

*   `width`: This controls the overall width of the cable channel.
*   `round`: A boolean or yes/no option to determine whether the top of the base will have rounded edges or square edges.

I'd like a main scad file that defines the cablechain module with the above parameters, and shows 3 links as described in the provided scad code - with the middle one visible, and the first and last partially transparent, as in the provided example.

Hey, I need some help designing a parametric nut trap for a CNC router tool holder, and I think I've got all the details you'll need. I'm kind of basing it off something I found online, but I need it to be fully flexible.

Basically, it's a cylindrical base with two nut traps cut into it for M3 nuts. The goal is to have the dimensions fully adjustable through parameters, so I can easily tweak it for different setups.

Here's the breakdown of the parameters I need:

1.  **Nut Spacing (NutSpacing):**  The distance between the centers of the two nut traps. The original design I was looking at used 76.2mm, but this needs to be adjustable for different setups. This needs to be a parameter.
2.  **Nut Trap Diameter (THNT_Dia):** The diameter of the cylindrical base. The example had 21mm, but, again, I might want to change that.
3.  **Nut Trap Resolution (ires):**  This determines how many segments are used to create the roundness of the cylinder.  More segments mean a smoother cylinder, but higher computation cost. I used 96 for the sample, which seemed like a good compromise for a 21mm diameter.
4.  **Bolt Hole Diameter (M3Dia):** The diameter of the holes for the M3 bolts that will secure the nut trap. This should be slightly bigger than the bolt itself (I had 3.6mm).
5.  **Bolt Hole Resolution (M3_ires):** The resolution for the bolt holes (number of segments to define the circle). I used 24 in the original.
6.  **Nut Diameter (M3NutDia):** The outer diameter of the nut, which for an M3 is around 9.18mm.
7. **Nut Height (M3Nut_Ht):** The height of the nut, which is 4.7mm for an M3 nut.
8.  **Left Nut Trap Offset (LtNutOffset):** The distance from the left edge of the base cylinder to the center of the first nut trap. Original design was 19.05mm
9.  **Right Nut Trap Offset (RtNutOffset):**  The distance from the *right* edge of the base cylinder to the center of the second nut trap. Originally 6.35mm, but I adjusted this to 8.35mm.
10. **Nut Rotation (RotNut):**  The rotation angle of the nut traps. I had options of 0 for the nut flat facing the sides, or 30 degrees for the nut flat faces parallel with the end of the part. This parameter will have drop-down box with those two options.
11. **Quantity (Qty):**  A parameter that determines whether to print one or two nut traps.
12. **Z-Origin (Z_Origin):**  A parameter for setting the Z-coordinate at which the nut trap is extruded. This can be used to make the base thicker or thinner. I was using -2 for a base that extruded above the z-plane.

I'd also like for the code to calculate the total length (Len) using `LtNutOffset + RtNutOffset + NutSpacing`. I also used a variable `RtNut_X` that is `Len-RtNutOffset` for use in determining the x-coordinate of the center of the second nut trap.

I think that's everything. Could you generate the OpenSCAD code for this?  No libraries needed, I don't think, just plain vanilla OpenSCAD. Let me know if you need anything clarified. I appreciate the help!

Okay, I'm looking to design a customizable corner joint for making polyhedral frames, primarily for use as a screen support. I need it to be parametric, so I can easily adjust the dimensions and the type of polyhedron it creates.

Here's a breakdown of what I need:

**Polyhedron Shape:**
*   I'd like to be able to choose between a Tetrahedron, Octahedron, Cube, Dodecahedron, and Icosahedron. The design should automatically adjust the angles based on the selected shape.

**Tubes:**
*   The number of tubes extending from each joint should be adjustable, with a maximum of 5. This will depend on the selected polyhedron shape - for example, a cube will only need 3, but a dodecahedron may need more.
*   The design should accommodate tubes with a specific radius (e.g., 4.95mm for a 10mm OD aluminum tube), and a specified depth of insertion.
*   There should be a slight taper at the ends of the tube insertion for easier assembly.

**Dimensions:**
*   I need to control the overall thickness of the joint itself, as well as the clearance between the tube and the joint's sleeve.
*   A key parameter is the depth to which the tubes are inserted into the joint
*   I need to be able to adjust the length of the small support "legs" that are used to make the joint, as well as their thickness.

**Magnet Support:**
*   A crucial feature is an integrated magnet support that can hold a thin film screen within the frame. This should accommodate a round magnet of a specified radius and thickness, with an air gap for clearance. The magnets should be set at a sufficient distance from the center of the joint. I'd like the magnet to be on the tips of the joint, that is, each face should have a magnet.

**Other:**
*   I need an option to include or exclude a small support that will act as a guide for the film screen.
*   I need parameters for a bolt and nut, as well as bolt head dimensions.
*   All the dimensions should be customizable, and the design should be robust and printable.
*   I'd like the ability to specify the $fn variable.

Could you please create a parametric OpenSCAD file or files for this? It seems like it could be broken down into smaller modules to make it easier to read. Also, I'd like the bolt and nut function to be separate modules, rather than primitives.

Hey, I'm looking for an OpenSCAD design for a tube clamp that can hold a GoPro. I need it to be parametric so I can adjust the tube diameter, clamp thickness, and mounting style.

Specifically, I'd like these features:

1.  **Tube Clamp:** The clamp should wrap around a tube of configurable diameter. I need to be able to set the tube diameter, the thickness of the clamp material, and the overall width of the clamp. It needs to be a split clamp design with bolts on either side to tighten it, and I need to be able to specify the bolt hole diameter. Also, I need to be able to choose between round holes, or holes sized for a hex nut. I also need to be able to specify the nut and bolt head size, as well as the contact thickness where the clamp is squeezed by the bolts. And lastly, I need to specify an offset for the bolt holes away from the center to ensure sufficient thickness of the clamp.

2.  **GoPro Mount Options:** I want two different GoPro mount options that are selectable:
    *   **Standard Tab Mount:** This is the standard two-pronged tab with a bolt hole that is compatible with most GoPro housings. I need to be able to set the mount height, the mount width, the tab width, the tab slot width, the bolt hole diameter, the bolt nut width, and an inset value for the mount to sink into the clamp. I also need the nut flare and nut flare width.
    *   **Quick Release Buckle Mount:** This should be a slot for a standard GoPro quick-release buckle. I need to be able to specify the overall buckle mount height, its overall length and width, the inside width of the area where the buckle slides in, the inside height of the slot, the width of the alignment ridge in the center, the height of that ridge, the overhang over the buckle, the thickness of the overhang, the inset of the buckle mount into the clamp, a rounding value, and a ridge rounding value. I also need to be able to specify a notch width on the overhang.

3.  **Mount Positioning:** I need the option to rotate the mount on the clamp in 90-degree increments, and to rotate the buckle mount sideways in 90-degree increments so I can mount to a vertical tube while keeping the camera oriented properly. I also need the option for the buckle mount to be either centered on the clamp or offset to one side.

4.  **Build Modes:** I want the option to generate the whole thing, just the top half, or just the bottom half, in print orientation.

It would also be great to have a variable for the resolution of the model using `$fn`.

I think that covers it all! Please let me know if you have questions.

I'm looking to create a parametric bearing in OpenSCAD. I'd like the design to calculate the optimal number of ball bearings based on the specified dimensions and tolerance, and then adjust the bearing race diameter so the gaps between the bearings roughly match the tolerance. This is what I'm envisioning:

*   **Parameters:**
    *   `Outer_Diameter`: The outer diameter of the bearing.
    *   `Hole_Diameter`: The diameter of the inner hole of the bearing.
    *   `Thickness`: The thickness of the bearing, which is also the diameter of the ball bearings.
    *  `Tolerance`: A tolerance parameter to control the spacing between the ball bearings.

*   **Functionality:**
    1.  **Optimal Ball Count Calculation:** The code should determine the best number of ball bearings to use, without them overlapping. It should start by calculating the circumference of the center of the race, and then determine the maximum number of ball bearings that can fit around it based on ball diameter and the tolerance.
    2.  **Race Diameter Adjustment:** Based on the calculated number of ball bearings, the code should adjust the diameter of the ball race to ensure that the gaps between the ball bearings are as close to the specified tolerance as possible.
    3.  **Tolerance:**  The ball bearings should not touch, with the spacing between each being as close to the specified `Tolerance` as possible. It should ensure the diameter of the race does not place the bearings too far inwards or outwards.
    4.  **Bearing Geometry:** The design should create:
        *   An outer ring.
        *   An inner ring (hole).
        *   A channel for the ball bearings.
        *   The ball bearings.

I think it would be good to include error checking to make sure that the bearing is at least printable. I don't expect any additional libraries like BOSL to be used for this, just base OpenSCAD functionality.

Hey, I'm looking to generate some custom connector housings for my electronics projects, specifically for those standard male and female header pins. I'd like to be able to create housings that hold a variable number of pins, either in a single or double row. It's also important to have the option of including wire dividers to help keep things neat, as well as a strain relief section for the cable. Oh, and it'd be super helpful to have a small orientation indicator on the housing.

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

*   **Number of Pins:** I need to specify the number of pins in a single column.
*   **Column Type:**  I need to be able to choose between single or double column of pins.
*   **Wire Separators:**  A boolean to turn wire separators on or off.
*   **Height:** The height of the main housing body.
*   **Wall Thickness:** The thickness of the walls of the housing.
*   **Header Dimension:** I need to specify the dimension of the plastic part of the header pins (usually about 2.5mm) which will be used to calculate the space for the header.
*   **Socket or Plug:** A setting to account for whether the connector will be a plug or a socket (sockets are typically a bit longer to accommodate the pin).
*   **Orientation Indicator:** A boolean for including an orientation indicator, and its position (left or right).
*   **Nozzle Diameter:**  For adjusting the internal dimensions for my specific 3d printer nozzle.
*   **Strain Relief:** A boolean to include a strain relief section.
*   **Cable Radius:**  The radius of the cable exit from the strain relief.
*   **Strain Relief Height:**  The height of the strain relief section.
*  **Strain Relief Cut Adjustments:** Separate X and Y adjustment factors for the cut-out where the header housing fits into the strain relief shell. This is useful for getting a nice tight fit when printing.

I'd also like to have the option to include the blocking bar used for lodging the header into place if the wire separators aren't included. The orientation indicator should be on the correct side of the housing, or the strain relief, if that is included. I’m also thinking that it could be good for the strain relief shell to have an indicator as well, that matches up to the header housing. I'm also looking for this to be relatively efficient and easy to customize so it will be good for generating housings with a wide range of numbers of pins.

I'd like the design to be parametric, so I can easily change these values within the customizer. Could you generate the OpenSCAD code for this?

Also, I don’t want any of the libraries included in this - I'd like it to be pure OpenSCAD code, please. I need it to work with all the options, and I would want it to be configurable within the customizer.

Hey, I'm looking to create a mount for a bicycle chainring, and I have some specific requirements. I want a design that I can 3D print, so it needs to be relatively robust, or at least flexible enough not to shatter. I have some code already, but I'd like to start fresh with something more parameterized.

Here's the basic idea:

It's a circular mount that will attach to a bicycle crank using four bolts. There needs to be a central opening and four bolt holes. The mount will have a raised section on top with a cross pattern to increase strength. I also want to add a retaining wall on the back that will keep the chainring centered. I'm aiming for something similar to a spider for a bike crank but with a retaining wall at the back.

The main variables I need to control are the BCD (Bolt Circle Diameter), which determines the bolt hole positions, and the number of teeth on the chainring. I'd also like to be able to adjust the bolt head size, overall height of the base, height of the rise, and the thickness of the retaining wall.

Specific parameters:

*   **BCD (Bolt Circle Diameter):** This is the diameter of the circle that passes through the center of the bolt holes. It will be a key input to calculate bolt hole positions.
*   **Teeth:** The number of teeth on the chainring. I need this because the diameter of the main body of the mount will change based on this.
*   **Bolt Head Size:** The diameter of the bolt head, used for the bolt hole cutouts.
*   **Bolt Height:** The height of the bolt hole cutouts.
*   **Base Height:** The height of the main circular base of the mount.
*   **Outer Base:** The height of the flat section of the main circular base that will attach directly to the crank.
*   **Rise:** The height of the raised section, which connects the base to the chainring.
*  **Wall Width** Thickness of the retaining wall.
*   **Total Height:** Calculated height from base and rise.
*   **Cutout:** The dimension of the length and width for the cross patterns.

I'd like to use the following libraries: BOSL2

Could you create the OpenSCAD files to generate this? I am mostly interested in the final part and the retaining wall together in a single part, but all parts should be parameterized and independent.

Thanks!

I need to create a 3D model that has a text element extruded both linearly and with an offset.

Here are the specifics:

1.  **Text:** The text itself, its font, and its size should be adjustable parameters. Also, the spacing between characters should be configurable. Let's default the text to "Sample," the font to "Times New Roman," the size to 10, and the character spacing to 1.

2.  **Extrusion:** The text should be extruded in two ways: a) linearly by a small amount (let's default this to 2mm), and b) linearly by a different, configurable height that is separate from the offset extrusion height. The second linear extrusion is Z in the included scad file. Z defaults to 2. The first extrusion is an offset of the second extrusion and defaults to 1 mm.

3.  **Offset:** Before the first extrusion, the 2D text should be offset by a configurable amount. Let's default this offset to 1mm.

4.  **Positioning/Sizing:** The combined extruded text should be centered around the origin on the X axis and sitting on the XY plane. Its dimensions along the X axis are also adjustable, as is the Z height. Default the X axis length to 20 and the Z axis height to 2.

5.  **Visualization Aids:** To help me see the dimensions and positioning of the main text object, could you also include a series of small cubes on all three axes, arranged with a 10mm spacing and 1mm size up to a count of 10. These don't need to be adjustable, but they should be rendered in alternating colors, so I can distinguish each cube.

6.  **Color:** The extruded text should be blue.

I would like all of this defined parametrically so I can change the values easily. I think it would be easiest as a single .scad file.
