I'd like a parametric OpenSCAD design for an egg holder. I need to be able to specify the number of egg holders in both the length and width directions. For example, I want to be able to say I want a 2x6, 6x6, 4x3, 1x1, or any other combination. The base of the holder should automatically adjust to accommodate the specified number of egg holders, making sure it fits the total layout.

I also need an option for a "minimalistic base." This should only be used when there is more than one row and column of egg holders, and it would create a base that's just the size of the egg holder grid, rather than a larger platform underneath. If I select a single row of holders, or a single column, it should revert to using a standard base. And I need the option to generate only the footprint of the egg holder layout so I can measure it against a surface.

The egg holders themselves should be cone-shaped with a flat base that fits on the main base platform. The diameter at the bottom of each cone should be smaller than the diameter at the top. It should be a hollow cup with walls of a set thickness. I would like to specify a set of parameters, such as wall thickness, height, and the diameters of the top and bottom. Finally, there should be a set gap between the holders. I'd like all dimensions to be parametrically defined, so all the dimensions can be changed.

Could you please generate the OpenSCAD file(s) for this design? I'd like it to be fully parametric, so I can change all those values easily. I don't have any preferences on how the file(s) are structured, other than that they should be parametric, and that I don't need any specific libraries.

Hey, I'm looking to create a custom container, kind of like a bottle, with a screw-on top that's compatible with standard PCO1881 bottle caps. I found a design online that's close to what I want, but it uses an STL import for the cap, which makes it hard to customize. I'd like a fully parametric design I can tweak in OpenSCAD, particularly the overall height and the knurled texture on the outside.

The basic shape is a cylinder, and then the top has the specific shape that fits a PCO1881 cap. The sides should have a knurled texture, almost like a series of small threads going both directions around the cylinder. I'm thinking we can generate these using linear_extrude and rotation.

I need to be able to easily adjust the following:

*   **Body Height:** This should change the main cylindrical height of the container body, without altering the top part.
*   **Knurl Height**: The height of the knurled texture, and if possible also the width of the individual lines/ridges.
*  **Number of knurl lines**: How dense or spread out the knurl should be.

Can you create an OpenSCAD design that does all of this? I don't want to use any pre-existing STLs. This should be a fully parametric design I can adjust in OpenSCAD. I don't really need the STL file for the bottle top to be rendered in the code, but it would be nice if the code created a matching screw-on top (that fits the PCO1881 threading) as a separate model so I can export it and test-print them separately. Also, I'd prefer to avoid any libraries except if there's something that's really necessary that I am not aware of, in order to keep the .scad files simple.

I'm looking to create a parametric OpenSCAD model of a cylinder with a hexagonal knurled surface. The knurling should be adjustable in terms of the height of the nubs, the number of nubs around the circumference, and how blunt or sharp they are. I'd like to be able to specify the radius of both the top and bottom of the cylinder, so it can be a cone as well.

Specifically:

*   **Cylinder Height:** This should be a parameter.
*   **Bottom Radius:** This should be a parameter.
*   **Top Radius:** This should be a parameter; defaulting to the bottom radius if not specified for a true cylinder.
*   **Nub Height:** This should control the height (or depth, if you will) of the hexagonal nubs.
*   **Number of Circumference Nubs:** I need to be able to control the number of nubs arranged around the cylinder's circumference.
*   **Nub Blunting:** This should control how sharp or flat the hexes appear; a value of 0 will result in sharp corners, and a higher value (approaching 1) will flatten them more. This should likely be a value from 0 to just under 1.

I'd like the code to handle the necessary calculations to achieve this. I'm thinking that it should also automatically figure out the number of nubs vertically along the cylinder, but I'd like to provide the flexibility to override this if need be.

I'd really like this in a self-contained file. No need to worry about external libraries.

I'm looking to create a modified version of a handwheel, and I need some help with the OpenSCAD code. I've been using the handwheel design from Thingiverse thing:5550987, which uses NopSCADlib and Round-Anything. I'd like to move away from the standard design though and make something more like the handwheel in Thingiverse thing:2086, with an offset hub and angled spokes.

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

*   **Outer Diameter (od):** The overall diameter of the handwheel rim.
*   **Bore Diameter (bore):** The diameter of the hole in the hub for the shaft.
*   **Hub Thickness (hub_t):** The thickness of the hub.
*   **Hub Diameter (hub_d):** The diameter of the hub.
*   **Hub Offset (hub_offset):** The distance the center of the hub is offset from the center of the rim along the X-axis.
*   **Number of Spokes (spokes):** The number of spokes connecting the rim and hub.
*   **Spoke Diameter (spoke_d):** The diameter of the spokes where they attach to the rim.
*   **Spoke Angle (spoke_angle):** The angle of the spokes relative to a line directly between the rim and the hub along the X axis, and a line tangent to the rim on the far side of the hub.
*   **Handle Height (handle_h):** The height of the handle above the rim.
*   **Handle Radius Bottom (handle_rb):** The radius of the handle at its base.
*   **Handle Radius Thinned (handle_rt):** The radius of the thinned portion of the handle.
*   **Handle Radius End (handle_re):** The radius of the handle at its end.
*   **Handle Stub Length (handle_stub_l):** The length of the stub connecting the handle to the rim.
*   **Handle Stub Radius (handle_stub_r):** The radius of the stub.

I'd also like to include a nut trap for an M3 nut, similar to the original design, for securing the handwheel to the shaft. Please make sure to use the `nut_trap_pocket` module from NopSCADlib.

The original file I was using included the following modules in addition to what I already listed: `teardrop`, `hub`, `handle2`, and `spoke`, although these would all need to be rewritten to accommodate the angled spokes and offset hub.  I was also using `polyRound` from the Round-Anything library and the nut_trap functions from the NopSCADlib library.

I’m not sure the best way to approach creating the angled spokes. I'm hoping the AI can figure that part out. I'm not concerned with the specific shape of the spoke, so long as it gets the job done and looks clean, it's fine with me. It would be nice if the rim and hub had a consistent thickness as well.

The goal is to create a fully parametric OpenSCAD file that can be easily customized. Please generate the code, and let me know if you have any questions.

I need help designing a parametric text stencil generator in OpenSCAD. I've seen a few examples out there, but I'd like one that has a lot of flexibility built-in. I need to be able to control the size of the stencil, the text content, font, alignment, and a few other things.

Specifically, here's what I'm looking for:

*   **Template Dimensions:** I need to set the overall width, length, and thickness of the stencil. All should be easily adjustable using variables. I'd like to be able to set a minimum for each if possible.
*   **Text:** The text itself should be a variable.
*   **Text Size:** This should also be a variable, controlling the height of the characters.
*   **Text Spacing:** Control over the spacing between characters is important.
*   **Text Alignment:** I need both horizontal (left, center, right) and vertical (top, center, bottom) alignment options.
*   **Text Orientation:** This is critical – I need the option for left-to-right, right-to-left, top-to-bottom, and bottom-to-top text flow,
*  **Fonts:** Access to the standard fonts available in OpenSCAD.  A really large selection would be helpful for a variety of projects.

I want to use OpenSCAD because of the customizer app in Thingiverse, so I can easily create different stencils for others to download and use. I would like a file that has the variables specified at the top for easy adjustment. I'd also like a suggestion on which fonts might work best as stencils because some may not render as desired. Finally, can you add a small border around the stencil as a visual indicator when the text doesn't fill the entire template?

I don't need any specific libraries, just the base OpenSCAD functionality, please. Thanks!

Hey, I'm looking to create a customizable dimpled cylinder in OpenSCAD, and I've got a pretty specific idea in mind. I'd like it to be parametric so I can adjust several aspects, and I'm hoping you can help me generate the code.

Basically, I want a cylinder with hexagonal dimples evenly spaced around its surface. Here's what I need to be able to control:

*   **Overall Cylinder Height:** I need to set the height of the cylinder.
*   **Bottom and Top Radius:** The cylinder should be able to taper, so I need separate radii for the top and bottom.
*   **Dimple Depth:** I need to be able to control how deep each dimple is.
*   **Number of Dimples:** I need to specify how many dimples are spaced around the circumference.
*   **Dimple Blunting:** The dimples should be either sharply defined or have a flat section between them. This will essentially control how sharp the ridges between the dimples are. I want to control the ratio of flat to curve, from 0 (sharp point) to 1 (completely flat).
*   **Number of Dimple Rows (Optional):** It would be nice to have an option to control how many rows of dimples there are vertically. If this is left undefined, the dimples should be automatically distributed to roughly equal a hex pattern. I'd like the height of each dimple to be about equal to the width of each dimple.

I'm not too concerned about the exact formula being used as long as the dimples are hexagonal and evenly distributed around the cylinder. I also want to avoid using any libraries for this.

Can you generate the OpenSCAD code for me? Thanks!

I'm looking to create a parametric, in-place printable ball bearing in OpenSCAD. I'd like the design to have a few key features:

1.  **Parametric Design:** I need to be able to easily adjust the inner and outer radii of the bearing, the radius of the ball bearings, the width of the channel, the number of balls, and clearances for printing.

2.  **In-Place Assembly:** The bearing should be designed to print fully assembled, requiring only support removal.

3.  **Support Generation:** I need an option to automatically generate internal supports within the bearing that prevent it from fusing during printing. These supports should also be parametric, allowing me to control the clearance from the bearing surfaces.

4.  **Debug Mode:** I'd like a debug mode that lets me visualize the 2D profile of the bearing cross-section without performing the rotation. This would be helpful for fine-tuning the parameters before generating the full 3D model.

5.  **Modular Code:** The design should be created using modules. This includes a core bearing module and a support generation module so that each part of the design can be updated without affecting the other unnecessarily.

For the parameters, I'm envisioning:

*   `innerR`: Inner radius of the bearing.
*   `outerR`: Outer radius of the bearing.
*   `channelHoleW`: Width of the channel where the ball bearings will sit.
*   `ballR`: Radius of the ball bearings.
*   `ballCount`: Number of ball bearings.
*   `clearance`: Clearance between the balls and bearing races for printing.
*   `supportClerance`: Clearance between the supports and bearing races (if support generation is enabled).
*   `supports`: Boolean to enable/disable support generation.
* `debug`: Boolean to enable debug mode to display a single 2D profile.

I am not using any libraries for this project. Thanks!

I'd like to design a parametric display stand in OpenSCAD. I need it to hold an item at a specific angle, and I want to be able to adjust several dimensions.

Here are the parameters I need to control:

*   **item_depth**:  This will be the thickness of the object being held in millimeters.
*   **width**: The overall width of the stand, also in millimeters.
*   **support_depth**: The depth of the rear support leg in millimeters. A good starting point is 45% of the width.
*   **height**:  The total height of the stand in millimeters.
*   **angle**: The angle, in degrees, at which the item will be displayed relative to vertical.
*   **base_h**:  The height of the platform at the base of the stand, in millimeters.
*   **preview**: A boolean to toggle the display of rounded edges. I want this to be fast when it's `false`, and prettier, but slower, when it's `true`.
*   **plate_mode**: A boolean, when true makes the stand work better for plates. In plate_mode, the height should be set to the radius of the plate.

The stand should have a kind of tripod shape, created from a pyramid-like form. It will have a base platform with holes for bolting it down. It should also have two "item catch" parts on the front of the stand, these will be small cuboidal shapes with rounded edges, that stop the displayed object from sliding off. These item catch parts should also have a small support structure, that will vary depending on plate_mode.

When plate mode is enabled, a plate object should be displayed in the stand.

I'm not using any specific libraries right now, but I expect you might use the minkowski() function, and others built-in to OpenSCAD.

Could you generate the OpenSCAD file(s) for this?

I'm looking for an OpenSCAD design for a simple, customizable fridge handle. I want it to be easily printable and have parameters for the mounting hole distance, hole inset from the edges, the hole diameter, and the overall thickness of the handle.

The handle should have two mounting holes, and a central section that's a little wider and more comfortable to grip.

I've got a few specific ideas about how it should look:

*   The main body should be a kind of rounded rectangular shape, sort of like a stretched capsule or a rounded race-track.
*   The mounting holes should be created by cutting cylindrical holes all the way through the handle.
*   There should also be cylindrical cutouts that are wider than the mounting holes that go partway into the handle on the top and bottom surfaces.
*   Finally, I'd like to be able to cut out a section in the middle to allow more space for fingers to grip the handle. This cut out should also have rounded ends.

I don't have any code yet, so I'm starting from scratch. I'm hoping you can provide the complete OpenSCAD file(s) for this design. I don't need any external libraries for this.

	translate([(holeInset + holeRadius +holeDistance ), holeInset + holeRadius, -1]) cylinder(h=100, r=holeRadius, $fn=100);

	translate([(holeInset + holeRadius), holeInset + holeRadius, thickness - 1]) cylinder(h=100, r=holeRadius*2, $fn=100);
	translate([(holeInset + holeRadius +holeDistance ), holeInset + holeRadius, thickness - 1]) cylinder(h=100, r=holeRadius*2, $fn=100);

I want to design a parametric GoPro pipe mount using OpenSCAD. I'm envisioning a clamp that wraps around a pipe and has a standard GoPro mounting interface. I'd like to be able to customize the mount for different pipe diameters and orientations of the GoPro mount.

Here are the specifics:

**General Structure:** The mount should consist of two halves that clamp around the pipe. One half will have the GoPro mount, and both halves will have screw holes and optional nut recesses for assembly.

**GoPro Mount Parameters:**
*   **Nut Recess:**
    *   Shape: Can be either a 4 or 6 sided polygon.
    *   Outer Diameter: This is the outer diameter of the nut recess.
    *   Depth: Depth of the nut recess.
*   **Hook Height:** The height of the GoPro mounting legs.
*   **Hook Leg Width:** Width of the GoPro mounting legs.
*   **Orientation:** The GoPro mount can be either horizontal or vertical relative to the pipe.

**Pipe Mount Parameters:**
*   **Pipe Diameter:** The diameter of the pipe the mount will clamp onto.
*   **Pipe Mount Thickness:** The thickness of the mount material.
*   **Screw Diameter:** The diameter of the screw holes.
*  **Nut Recess**:
    *  Shape: Can be a 4 or 6 sided polygon
    *  Outer Diameter: Outer diameter of the nut recess.
    *  Depth: Depth of the nut recess.

**Advanced Parameters:**
*   **Pipe Mount Center Offset:**  An offset for the position of the pipe mount.
*   **Assembly Clearance:**  A small clearance around screw holes.
*   **Global Curves Resolution:** This can be used to define the resolution of curves.

**Parts to print:** I'd like to be able to generate either both halves of the clamp together or separately as upper and lower parts.

I'm using the "GoProScad" library from github.com/ridercz/GoProScad which I believe provides standard GoPro interface modules. I don't need to specify files within this library.

Could you provide the necessary OpenSCAD code?

I'm looking to create some custom holders for my DeWalt Tough Cases, specifically for bits and jigsaw blades. I'd like them to be parametric so I can adjust them for different sizes and configurations. I'll need a library file to handle some common functions and parameters, and then separate files for the different types of holders.

For the library, `DeWaltLibrary.scad`, I'll need to define things like:

*   `EnableDebug`: A boolean to control whether debug info is printed
*   `HexBitClearance`: A value to adjust the clearance for hex bits
*   `HexBitFaceToFaceWidth` and `HexBitTipToTipWidth`: Calculations based on the 1/4" hex shank dimensions, taking `HexBitClearance` into account.
*   `arraySum` and `partialArraySum`: Functions for calculating sums of array elements and partial array sums.
*   Parameters and modules for generating the DeWalt dovetail tab, including `TabAngle`, `TabBottomOuterWidth`, `TabBottomInnerWidth`, `TabTickness`, `TabDistance`, `TabTotalTickness`, `maximizeTabNumber`, `TabTopWidthDifference`, `TabTopOuterWidth`, `TabTopInnerWidth`, `generateTab`, and `generateTabTest`.

For the bit holders, `DeWaltAngledBitHolder.scad` should do the following:
*   `ObjectToPrint` parameter to specify which component to render.
*   `InsertWidth`, `BitAngle`, `DepthInBits`, `WidthInBits`, `BitHolderBottomWallTickness`, `BitHolderGrip`, `BitHolderHeight`, and `InsertHeight` parameters that define the size and shape of the holder.
*   `BitTightenerDiameter`, `BitTightenerLength`, `MinimumDistanceBetweenBits`, `BitHolderLength`, `BitHolderDepth`, `BitHolderDepthBorder`, and `BitHolderDepthOverlap` parameters.
*   Calculations of `BitClearance`, `InsertDepth`, `ExtraDepth`, `BitTightenerOffset`, and `tabNumber` based on other parameters.
*   A `generateBitHolderKnockOff` module to create a single bit holding feature at a specified position and angle.
*   A `generateMainBody` module to generate the main body with cutouts for the bits.
*   A `generateBitHolder` module that creates the complete bit holder including the main body and tabs.
*   A `generateHolderTest` module to generate a test object.

For the jigsaw blade holders, `DeWaltJigsawBladeHolder.scad`, I'll need:

*   `ObjectToPrint` parameter to specify which component to render.
*   `InsertHeight`, `InsertWidth`, `InsertDepth`, and `BladeTicknessConfiguration` parameters to control the size and the number of blades.
*   `JigsawBladeBackWallTickness`, `JigsawBladeUpperWallTickness`, `JigsawBladeTightenerDiameter`, `JigsawBladeTightenerLength`, `JigsawBladeTightenerHorizontalOffset`, `JigsawBladeTightenerVerticalOffset`, and `MinimumDistanceBetweenJigsawBlades` parameters.
*   A `generateMainBody` module for the main body and tabs.
*   A `generateJigSawBladeKnockOff` module to create the blade-holding feature.
*   A `generateJigSawBladeHolder` module to assemble the holder.
*   A `generateJigSawBladeHolderTest` module for a test piece.

And finally for the long bit holders, `DeWaltLongBitHolder.scad`:
*   `ObjectToPrint` parameter to specify which component to render.
*   `InsertHeight`, `InsertWidth`, and `InsertDepth` for the overall size.
*   `BitsConfiguration` parameter for specifying the width of each bit in the holder
*   `BitCenterHeight` parameter for the center height of the bit holders.
*    `HexHolderOffset` parameter to control the fit of the hex bits.
*   `BitHolderBackWallTickness`, `BitHolderTiltCover`, `BitHolderTiltHole`, `BitHolderTightenerDiameter`, `BitHolderTightenerLength`, `BitHolderTightenerOffset`, and `MinimumDistanceBetweenBits` parameters.
*   Calculations of `HexBitFaceToFaceWidth` and `HexBitTipToTipWidth`
*   A `generateBitHolderKnockOff` module to create the bit holding feature.
*   A `generateMainBody` module to generate the main body with tabs.
*   A `generateBitHolder` module to assemble the holder.
*   A `generateHolderTest` module for testing.

All the files should include the standard header and license information from my examples.

I think this should cover everything. Let me know if you have any questions.

I'm looking to create a parametric PCB holder, similar to what I've seen others use, but I want to be able to customize it for different board sizes and mounting configurations.

The basic idea is a set of support rods with pegs that the PCB sits on, connected by cross beams. I'd like to be able to choose if I have a central support, and if I want a screw plate for mounting the whole thing to something else. I also need the option to have board holders, which are those little cube-like pieces that help keep the PCB from sliding around. I want all of these to be customizable.

Here are the parameters I'm thinking of, and the kind of control I'd like to have:

*   **Board Dimensions:**
    *   `X` (float): Width of the PCB.
    *   `Y` (float): Length of the PCB.
*   **Rod and Peg Details:**
    *   `D` (float): Diameter of the support rods.
    *   `DP` (float): Diameter of the pegs that the PCB sits on.
    *   `RH` (float): Height of the support rods.
    *   `SH` (float): Diameter of a hole in the rods for a screw if needed (can be 0).
*   **PCB and Edge Distances**
    *   `PCH` (float): Thickness of the PCB.
    *   `Ex1` (float): Distance from the left edge of the PCB to the support rod/peg.
    *   `Ex2` (float): Distance from the right edge of the PCB to the support rod/peg.
    *   `Ey1` (float): Distance from the top edge of the PCB to the support rod/peg.
    *   `Ey2` (float): Distance from the bottom edge of the PCB to the support rod/peg.
*    **Beam and Base Details**
    *   `BH` (float): Height of the cross beams.

*   **Features**
    *  `Board_holders`: boolean to turn board holders on/off
    * `Sentral_support`: boolean to turn central support on/off
    *   `Screw_plate`: boolean to turn the screw plate on/off.

I'd also like it if I could control visibility; for example, the PCB outline should be something I can switch on or off for visualization. The visibility is the same as the "show PCB" parameter from the example I looked at.

Could you generate an OpenSCAD file that allows me to configure all of these things? I’m not looking for external libraries like MCAD or BOSL for this, I just need a basic SCAD file using built-in functions.

Hi, I'm looking for a way to generate a customizable shop vac adapter in OpenSCAD. I need it to be parametric so I can easily adjust it to different vacuum and tool sizes. Here's what I'm envisioning:

The adapter should have a cylindrical base that connects to the shop vac hose. This base needs to be configurable by its diameter and the length of the overlap between the adapter and hose. It also needs a bit of taper as it transitions away from the vac hose for a tighter fit (also configurable).

Then, there should be a section that chamfers (or rather transitions with a curved section) from the circular base to the final tip shape. I need to control the length of this chamfer area.

The tip needs to be customizable as well. It should be able to have a rectangular, elliptical, or circular shape, all of which need to have their dimensions customizable (height, width, or radius). I need to also control the overall length of the tip. Also the corners of the tip shape should be filletted, and the amount of fillet should be controllable.

There should also be a flange that can be added to the end of the tip, for mounting the adapter for dust collection purposes. This flange needs to have adjustable width and thickness, and also the option to not have a flange at all. It would also be nice to control the number of mounting holes in the flange and their radius. The flange should be on the back of the tip and should be at an angle relative to the tip section.

Finally, I need to be able to control the overall material thickness of the adapter.

I'm looking for a single OpenSCAD file that includes all of this functionality. I've got some experience with OpenSCAD so the only library that I expect to use would be built into OpenSCAD. Let me know what you come up with!
