I'm looking for an OpenSCAD design for a dual-ended hex bit driver. I've got some specific dimensions and a couple of requirements that I'd like to be able to easily change.

Here's the general idea: it should be a cylindrical handle, with a hex socket on each end. One end should take a standard 1/4" hex bit, and the other end should take a smaller bit, about 4mm in diameter. I'd also like to include space for magnets in each socket, to help hold the bits in place. The user should be able to control the depth of the sockets and the magnet pockets, as well as the overall length of the tool, the thickness of the handle and how many sides it has.

Specifically, I would like to be able to change these parameters:

**General Handle Parameters:**

*   `length`: The total length of the tool.
*   `side_thickness`: The minimum wall thickness of the handle.
*   `handle_sides`: The number of sides for the handle's cross-section, can have an alias of `handle_segments` as well.
*    `handle_thickness`: A multiplier for the radius of the handle relative to the sockets.
*   `tolerance`: A small amount of extra space around the bits, for easier insertion and removal.

**Bit 1 (Larger Socket) Parameters:**

*   `bit1_socket_diameter`: The diameter of the 1/4" hex socket
*   `bit1_socket_depth`: The depth of the 1/4" hex socket
*   `bit1_magnet_diameter`: The diameter of the magnet pocket
*   `bit1_magnet_depth`: The depth of the magnet pocket

**Bit 2 (Smaller Socket) Parameters:**

*   `bit2_socket_diameter`: The diameter of the smaller hex socket
*   `bit2_socket_depth`: The depth of the smaller hex socket
*   `bit2_magnet_diameter`: The diameter of the magnet pocket
*   `bit2_magnet_depth`: The depth of the magnet pocket

I'd like to see the final result as a single object, with the appropriate subtractions to create the sockets and magnet pockets. The handle should transition smoothly from one socket size to the other, so I think you'll need to use a `hull` to create the body shape.

I'd like the code to be organized for readability, so please use comments to explain each section. It should not rely on any external libraries.

I need an OpenSCAD design for a replacement garden valve handle. The original metal handle has these small ridges that are really hard to grip, so I want to make one that's easier to turn.

Here are the specifics:

*   **Shape:** I'd like a central cylindrical piece where it attaches to the valve stem. This central piece will have a hole for the valve stem, which can be either hexagonal or square, and this opening needs to be tapered for easier insertion. On the outside of the central cylinder, I want three handle "bumps" or ridges spaced evenly (120 degrees apart).
*   **Handle Size:** I need it to be parametric for two handle sizes, small and large. This affects how long the bumps/ridges are and the diameter of the central cylinder.
*   **Shaft Hole:** The hole for the valve stem should be parametric for both hex and square shapes. The dimensions for these holes need to accommodate a range of sizes with a small minimum and larger maximum dimension and a taper at the entry. Also, there should be a through-hole for a screw to secure it to the valve stem.
*   **Handle Height:** I want the height of the central cylinder to be adjustable for small and tall versions.
*   **Handle Bump/Ridge Design:** The handle bumps should be larger than the original ones with more leverage, and they should be attached to the central cylinder by some method such as hulling.

I'd like the design to be parametric so I can easily adjust different aspects of it. I'm also not sure which libraries would be useful, but I do know that I want the following features to be implemented:

*   **Parametric design**: The design should have parameters for shaft shape (hex or square), shaft size range (min and max), handle size (small or large), and overall height.
*   **Tapered shaft openings**: The shaft openings need to be tapered to help guide the valve stem into the handle.
*   **Three ridges**: The handle design should have three ridges that are easy to grip, spaced 120 degrees apart around the central cylinder.
*   **Screw hole**: A hole for a screw should be included for fastening the handle to the valve stem.

I think that's it, let me know if you have any questions.

I'm looking to create a parametric OpenSCAD design for dowel centers. These are little tools you insert into a drilled hole on one piece of wood, then press the other piece of wood against them to mark the exact spot to drill a matching hole. I'd like to be able to customize the design for different dowel sizes and depths.

Specifically, I need the following parameters:

*   **dowel\_units**: A way to switch between inches and millimeters for all dimensions. It would be a choice between 0 for inches and 1 for millimeters.
*   **dowel\_dia**: The diameter of the dowel the centers are intended for.
*   **dowel\_depth**:  The depth of the dowel hole. If set to zero, the program should make a best guess for the depth, making it about 4/3 the radius.
*   **hole\_dia\_oversize**: This is a bit of a magic number to make sure the centers fit properly. Default this to 0.43, and don't allow it to be set by the user.
*   **rib\_min\_thickness**: How thick (in mm) the base of the anti-friction ribs should be. Default to 0.3 mm. Don't allow the user to set it.
*   **rib\_thickness**: The overall thickness (in mm) of the anti-friction ribs. Default this to 0.6 mm and do not allow a user to set it.
*   **num\_ribs**: The number of anti-friction ribs. Default this to 6, and the user should not be allowed to change it.
*   **rib\_angle**: How many degrees the ribs tilt outwards. Default this to 1 degree and do not allow the user to change this.
*    **point\_sides**: The number of sides on the marking point. Default this to 4 and allow the user to set this.
*   **point\_radius**: The radius of the marking point. Default to 1.5 and allow the user to set this.
*   **point\_height**: The height of the marking point. If set to zero, it will be 4/3 of the radius, otherwise the user can input the height.
*   **rim\_overhang**: How much the rim overhangs. Default this to 1.5, and the user can set this.
*   **rim\_thickness**: The thickness of the rim. Default to 0.6, and allow the user to set it.
*   **fn**: The resolution (number of facets on the cylinders). Default to 48 and the user should be allowed to set this.

The design should have:

*   A central cylinder for the dowel with anti-friction ribs around it to grip the drilled hole.
*   A rim/overhang at the top that makes it easier to remove.
*   A sharp point at the very top to create the marking for the second drilled hole.

It should generate a single `.scad` file for the design. I'm looking for a pretty close replication of what I've shown you; I don't need any special features beyond this basic design. I'm not using any additional libraries, so the design can just rely on the built-in OpenSCAD functions.

Okay, I'm looking for a way to create a print-in-place fidget toy, and I really like the design of the "mathgrrl fidget star". It's a hinged cube that can fold from a box shape into a star (specifically, half of a Yoshimoto cube, apparently). It would be great if I could control the overall size of the cube and the hinge parameters.

Here's what I want the OpenSCAD design to be able to do:

*   **Two Main Assemblies:** I need two main ways to assemble the object, which are selected using a variable, like `assembly = "closed"` or `assembly = "standing"`. The "closed" version should start as a closed cube and the "standing" version should start as a flat star shape as seen in the provided images.
*   **Cube Shape:** I want a `shape` variable that I can set to "star", "snub", "cube", "crazy", or "doublestar" to control the general shape. These refer to a few of the different corner treatments seen in the original model, with `star` producing a star shaped outline, `snub` being a seven sided cube (missing a corner), `cube` resulting in a normal cube, `crazy` being a mixed star and poke shape, and `doublestar` having star shapes on both sides.
*   **Cube Height:** The main size parameter will be `cube_height`, which will control the dimensions of the individual cubes that make up the model.  This should be in millimeters.
*   **Hinge Radius:** The size of the hinge pin should be controlled by `hinge_radius`, also in millimeters.
*   **Hinge Clearance:** I need to be able to adjust the clearance around the hinges with `hinge_clearance` (also in mm).
*  **Stacking Clearance:** There should also be a `stacking_clearance` variable (in mm) to control the space between the different cubes in the stacked configuration.
*   **Corner Radius:** The corners should have a `corner_radius`, which is some fraction of the `cube_height` for a rounded look.
*   **Print-in-Place:** It is important that the design prints in one piece, with the hinges already functional, requiring no assembly.

I think I would like a variable named `fudge` which can help to provide small adjustments to the design as needed. I think that the `cone_height` variable should also be included to control the size of the cones inside the hinges.

I'm not sure about using specific libraries, but I think this is all pretty straightforward geometry, so it probably doesn't require any. I'm thinking a single .scad file should be able to do the job, but I'm open to multiple if it makes it more organized.

Can you help me with that?

Hey, I'm looking for help creating an OpenSCAD design for a customizable tube bracket for aquariums. I've seen some online but I want to make one myself that I can easily tweak for different setups.

Basically, I need a bracket that can hold glass tubes (for CO2 lines or other stuff), and it needs to clip onto the side of an aquarium tank. Here are the things I need to be able to adjust:

*   **`holeCount`**: The number of tubes the bracket should hold.
*   **`glassThickness`**: The thickness of the aquarium glass.

The bracket should have a few key features:

*   It needs to be printed standing on its side to avoid needing supports, so the main body of the design will be tall and thin, kind of like a "U" rotated on its side. The tubes will go through the arms of the "U" facing upwards when printed and attached.
*   It should have a flat part on the back to sit flush against the aquarium glass.
*   The clamp part should be kind of like a fork shape, that hugs the glass from the outside of the aquarium. There should also be a flat part to hold the tubes in the top and bottom. The top part of the fork will hold all of the tubes. The bottom part of the fork will be smaller but will have two screw holes and a slightly rounded shape.
*  For added reliability, there should be little bumps or sphere-like extrusions on the vertical part of the bracket to help prevent water from being drawn up the bracket due to capillary action.
*   I would also like rounded corners on the outer edge to add to the aesthetic of the print.

I'm not sure exactly how to best approach this with OpenSCAD and I haven't worked with it a lot before. Could you generate the .scad file for me? I don't need any extra libraries.

Okay, so I'm trying to design some customizable toy train tracks, similar to the ones I saw on Thingiverse by atartanian.  I'm really impressed with the flexibility of the design and how easy it seems to modify parameters using OpenSCAD, which I'm still learning.

My main goal is to have a parametric track system with a base, a middle section, and the male/female connectors at the ends.  I'd like to be able to easily modify the following:

*   **Track Length:** I need to be able to set the length of a track piece.
*   **Overall Dimensions:**  I should have the ability to define the width of the base, the width of the middle section, the height of the base, and the height of the middle section. I need control over the connector length as well.
*   **Track Type Presets:** I want to include a few track presets. The original design had custom and "Brio" presets that are fine.
*   **Extrusion Width/Line Thickness:** It's critical to be able to set the extrusion width for my printer, as well as the line thickness (as a multiple of the extrusion width) used to generate track lines.
*   **Connector Tolerance:** I need to be able to adjust the spacing between male and female connectors for a good fit.
*   **Flexibility:**  The flex track design that atartanian used is great - it involves these gaps and lines throughout the track that gives it the flexibility. I would like to keep this flexible pattern.

I'm envisioning this as an OpenSCAD project, and I'm looking for you to help me generate the .scad files, including any necessary modules or functions. I want the design to be parametric so I can make new track pieces easily. I don't need to include any external libraries, just a main .scad file that I can use directly to define and generate my track pieces.

Essentially, I want the user to define the parameters, and have the OpenSCAD generate the track using those parameters and the track design I described above.

Hey, I'm looking to create a parametric OpenSCAD file for a squareness check tool, kind of like the one used for MPCNC builds. I've got an existing SCAD file that does what I want, but it's kind of specific to my needs and I'd like to be able to easily customize it for different setups. The general idea is a flat base with two circular cutouts for pipes to fit into. There's also a rectangular cutout in the middle of the base.

Here's a breakdown of the key parameters I'd need to control:

1.  **Length Between Pipes:** This would be the distance between the centers of the pipe cutouts, and is directly tied to the length of the main base along the y-axis.
2.  **Width of Square Check:**  This would be the width of the whole base along the x-axis.
3.  **Thickness Between Inside Cut & Pipe Cut:** This is the width of the material between the rectangular cutout and the pipe cutouts, along the Y axis.
4. **Thickness on edges of inside cut:** This is the width of the material between the rectangular cutout and the edge of the base, along the X axis.
5.  **Height of Square Check:** This is just the overall height/thickness of the part.
6.  **Pipe Diameter:** This should be a parameter, so I can change the diameter of the pipe cutouts. I’d need to be able to specify a few sizes, like 23.5mm, 25.0mm, and 25.4mm, but it'd be great to allow any arbitrary diameter.
7.  **Cube Offset:** This refers to how far the outer edges of the base extend past the center of each pipe cutout, along the Y axis.
8. **Resolution of Pipe cut:** How smooth each circle should be.
9.  **Quantity:** Whether to make 1 or 2 square checks in the same print.  If 2 are requested, they need to be offset from each other by a small distance.

So, the main body should be a cube with the given width, total length (based on the distance between pipes + offsets), and the height parameters. Then, there should be cuts made in the base to create the rectangular cutout and circular cutouts for the pipes. The circular cutouts should have the specified pipe diameter and be located at the correct offset and distance from each other.

I think it would be beneficial to include comments to explain the different parameters, and maybe display the calculated values like the distance between the pipe cutouts using `echo()`. It would also be useful to use a module to create the basic square check, and then if the quantity is 2, just translate and call the module again to create the second square check. I'm not using any special libraries for this project, just the basic OpenSCAD functionality. I'm hoping you can help me generate a clean and customizable SCAD file for this.

Thanks!

Hey, I'm looking to create a customizable WiFi sign that I can 3D print. I've seen some examples online, and I'm imagining something similar but fully parametric.

Here's what I'd like:

**Overall Structure**

*   The sign should have a rectangular backplate with rounded corners.
*   There should be extruded text on the front of the plate for a welcome message, the WiFi network name (SSID), and the WiFi password.
*   I'd like the option to add holes in the top corners for wall mounting.
*   The entire design should be scalable in the XY plane.

**Text Elements**

*   **Heading Text:** This should be at the top, larger than the other text, and bold.
*   **Network Name:** Below the heading, should be clearly readable.
*   **Password:** Should be below the network name.
*   I want to be able to change the font family for all text elements. I'd like to use fonts that are commonly found on Google Fonts.
*   Each text element (heading, name, password) should have its own customizable font size.
*   The text should be extruded.

**Backplate**

*   The backplate should have a customizable width and height.
*   It should also have a customizable depth/thickness.
*   The corner radius should be adjustable.
*   The mounting holes (if used) should be circular, with an adjustable diameter, placed in the top corners.

**Extras**

*   I would like to be able to scale the whole model in the X and Y directions to easily change its size without having to adjust each dimension individually.
*   There should be a toggle to show or hide a small checkmark in the lock symbol. This can be useful to hide if making a small sign.
*   I want the design to be fully parameterized, with all these values accessible as variables at the beginning of the OpenSCAD file.

**Specific Visuals**

*   I'd like a WiFi symbol included, ideally something relatively standard.
*   A small lock symbol should be included near the password.

**Libraries**

*   I'm not asking for you to use any libraries, though if you have any you think would be useful I'm happy to hear about them!

I'm envisioning a user-friendly parametric design, so I'd prefer that all parameters be declared in the same file. Ideally, the file should define variables at the top that I can adjust, and the rest of the code should use those variables.

Can you help me create this OpenSCAD file? I am not sure about the proper way to generate the lock and wifi symbols.

I'd like to design a phone charger stand, but I need it to be compact and customizable. I'm thinking something similar to the designs on thingiverse (links below), but much smaller and more portable, like for a travel bag. I also need to be able to adjust the width for different phone sizes.

http://www.thingiverse.com/thing:247542
http://www.thingiverse.com/thing:15153
http://www.thingiverse.com/thing:7963

The design should have a base that holds a standard phone charger (the dimensions for my charger are in the attached code as charger_dimensions, and the charger itself will be scaled by 0.9). I'd also like a slot or groove in the base where the phone will sit upright during charging. This slot needs to be adjustable for the phone's width, so I want a variable for that (`phone_width` or similar). The phone's slot should be centered on the base. The charger shape and slot height are okay as they are in the example, but you may want to parametrically generate these values from the `charger_dimensions` and other dimensions for the best result. Assume the charger dimensions are fixed and should not be changed or parametrically generated.

Could you provide the OpenSCAD code for this? I don't need a ton of extra features but I would like it to be designed so it is easy to modify later.

Hey, I'm looking to design a heart-shaped box with a lid in OpenSCAD, and I've got some specific parameters in mind. I really liked the shape of the heart in that example file I found (the "Heart_shaped_box.scad"), and I'd like something similar, but I need it to be fully parametric so I can make adjustments.

Here's what I need:

**General Shape and Box Parameters:**

*   **Heart Shape:** The core heart shape should be created using a combination of a square and two circles, like in the original example. This shape should be able to be squashed or stretched on one axis for customization.
*   **Box Height:**  I need to control the overall height of the box.
*   **Width:** The overall width of the heart, from point to top, should be a parameter.
*   **Wall Thickness:** The thickness of the walls of the box should be adjustable.
*   **Base Thickness:** I need to set the thickness of the box's base independently from the wall thickness, as I sometimes prefer a thicker base.
*   **Squash/Stretch:** The heart shape should be able to be stretched or squashed (scaled) along one axis to change its appearance. I'd like this controlled by a parameter.

**Lid Parameters:**

*   **Lid Thickness:** The lid's thickness needs its own parameter.
*   **Lid Lip Height:** I need a parameter for the height of the inner lip on the lid that fits into the box.
*   **Lid Fit Adjustment:** This parameter would adjust the gap between the lid and the box, effectively making the lid fit tighter or looser, and should be adjustable.
*   **Cross Section View:** I would love an option to display a cross-section view of the box and lid to visually check the fit. This should be something like a toggle.
*   **Lid Color:** The lid should be colored differently so it's easy to distinguish when viewing or when creating a cross-section. I'd like to be able to set a specific color for this.

**Technical Details:**

*   **Minkowski:** The box should use minkowski sums to create the nice rounded edges that I really liked.
*   I would like to make sure all the shapes are aligned using transformations, not by using specific x, y, and z coordinate values in the core design.

I think that covers everything. Could you generate the necessary parametric OpenSCAD files for this? I'm not expecting you to use any pre-existing libraries, except the standard OpenSCAD library. I prefer that the file be written from the ground up.

I'm looking to design a custom mount for a phone on a DJI remote, specifically with a built-in sunshade. I want it to be easily customizable for different phone sizes and depths, and also let me control how deep the sunshade is.

Here are the basic features I need:

*   **Base Mount:** This will hold the phone and attach to the remote. It needs to be a robust block with cutouts for the phone.
    *   It needs to accommodate phones of varying width, height, and depth.
    *   There should be cutouts for the USB port, speaker, and home button.
    *   There need to be button cutouts on both sides to prevent accidental presses.
    *   The base needs to be a bit wider and taller than the phone to provide good support and a base for the sunshade.
*   **Sunshade:** A top piece extending forward to block sun.
    *   The depth of the sunshade should be parametrically controlled so I can use just a holder, or also have the full sunshade.
    *   The sunshade needs to have some kind of supporting structure connecting it to the base.
*   **Parametric Design:** All the key dimensions should be controllable as variables.
    *   Phone width, height, and depth
    *   Sunshade depth
    *   Base dimensions to be derived from the phone size to provide proper support
    *   Cutout positions for buttons, ports, etc, should be related to the phone size.

I have an existing design I can provide as reference, but I'd really like a parametric version from scratch. It also has some rounding on the outside that'd be nice to have.

I'd like to use OpenSCAD to create this. I'm okay with it not being a single file if that makes things easier for the parametric design. I don't need you to use any external libraries, it can all be done with primitives.

Hey, I'm looking for some help designing a customizable clamp and hook system for a project. I've seen some similar designs, but I need something that can tilt on two axes because my mounting bar isn't perfectly level.

Basically, I need a clamp that can attach to a cylindrical bar and a hook piece that attaches to the clamp and can hold something. I'd like the ability to adjust the tilt of the hook piece, both front-to-back and left-to-right, relative to the clamp.

Here's a breakdown of what I need, including some initial dimensions I'm thinking of in millimeters:

**Clamp Parameters:**

*   **Thickness:**  I'd like this to be adjustable; let's start at 5 mm.
*   **Width:** Adjustable too; maybe 21 mm to start.
*   **Inner Diameter:**  This will need to be adjustable for different bars; let's start at 33.5 mm.
*   **Clamp Tab Gap:** The gap between the clamp's tabs when open; let's say 3 mm initially.
*   **Slack:**  Some play between the clamp and bar; this could be an adjustable parameter; 0.35mm might work.
* **Tab Angle Adjustment:** This might be a tricky one - it's how much the tabs are angled when the clamp is open; something we might have to tweak.

**Hook Parameters:**

*   **Length:** How far the hook extends back from the clamp, maybe 120 mm to begin with, but it should be adjustable.
*   **Depth:** The depth of the hook, let's start with 22 mm.
*   **Lip Length:** How far the front lip extends, maybe 15 mm.
*   **Hook Screw Offset:** The vertical offset of the screw hole on the back side of the hook, relative to the point where the bottom of the hook is flush with the bottom of the clamp.  This might be zero to start.

**Fastener Details** (These should also be adjustable, since I might want to use different screw sizes):

*   **Screw Diameter:** Let's start with 3.2 mm for an M3 screw.
*   **Nut Diameter:** 6 mm for an M3 nut (corner to corner).
*   **Nut Thickness:** 2.4 mm for an M3 nut.
*   **Screw Head Diameter:** 5.5 mm for an M3 screw head.
*   **Screw Head Thickness:** 3.1 mm for an M3 screw head.
*   **Clamp Tab Screw Head Thickness:** We can allow this to protrude more, so maybe something like 2 mm.
*   **Clamp Ring Screw Nut Extra Height:** To make sure a longer screw doesn't stick out; 0.6 mm.

**Tilting Mechanism**
*   This is key - I need to be able to adjust the angle of the hook piece in two directions:
    *   Front-to-back tilt (around an axis perpendicular to the clamp's length)
    *   Left-to-right tilt (around an axis parallel to the clamp's length)
    *   These tilt angles should be independent and adjustable parameters.

I'd like the design to be done in OpenSCAD, and I'd like all the parameters listed above to be adjustable, so I can easily tweak the design. It would be fantastic if the design could use the `util.scad` library for fillets and rounded cubes.

Could you help me with this?

I'd like to design a grinding block in OpenSCAD, and I'd like it to be parametric so I can easily adjust the size. It'll be made of two parts: a base plate and a bracket that fits on top. The base plate will have a handle, and the bracket will hold the sandpaper in place. I'll need to be able to specify the dimensions of the grinding surface, the height of the bracket, the wall thickness of the bracket, and the handle dimensions.

Here are the specifics I'm envisioning:

*   **Base:**
    *   There will be a rectangular base plate, specified by `width`, `length`, and `height`.
    *   A handle will be centered on one of the sides of the base. The handle will be a rectangular prism specified by its `handleHeight` and `handleWidth`. The handle will have a length that fits within the base (and will be slightly less that the base width), and the handle will be located at `height`
*   **Bracket:**
    *   The bracket will fit onto the base, offset slightly by a `padding` value.  The bottom of the bracket will sit `height + padding` above the base.
    *   The bracket will also have a `bracketHeight` and a `bracketWall`.
    *   The internal width and length of the bracket need to be slightly smaller than the base to accommodate a sheet of sandpaper on the base. The bracket length will be a few millimeters shorter than the base length to allow for a small back end to the base.
*   **General:**
    *   I'd like a way to select if I want to see only the base, only the bracket or both for preview and rendering.

Could you generate the OpenSCAD code for this? I'm not using any special libraries at the moment, and the code should be clear and easy to follow. I'd like the design to be fully parametric, so I can easily adjust the dimensions. I'll use the customizer view, and I'd like to see the ability to select the viewable part. The preview view I'd like to be at `view:south west, tilt:top diagonal`.

grinding_block.scad:
```
// preview[view:south west, tilt:top diagonal]

/* [Base] */
// Width of the grinding surface
width = 60;
// Length of the grinding surface
length = 60;
// Height of the grinding surface
height = 3;

/* [Bracket] */
// The height of the bracket
bracketHeight = 5;
// Wall thickness of the bracket
bracketWall = 5;
// The padding between base and bracket has to fit the sandpaper and account for shrinking
padding = 1;

/* [Handle] */
// Height of the handle
handleHeight = 15;
// Width of the handle
handleWidth = 5;

/* [View] */
// Which parts would you like to see?
part = "all"; // [all:Base and Bracket, base:Base Only, bracket:Bracket Only]

/* [Hidden] */
backen = 5;
bracketWidth = width;
bracketLength = length - backen * 2 - padding * 2;

	difference() {

		translate([-1, backen, height])
			cube([width + 2, length - backen * 2, bracketHeight + 1]);
	}

	/* Handle */
	translate([backen, (length / 2) - (handleWidth / 2), height])
		cube([handleLength, handleWidth, handleHeight]);
}

module bracket() {
	innerWidth = bracketWidth - bracketWall * 2;
	innerLength = bracketLength - bracketWall * 2;
	bracketHeight = bracketHeight - padding;

	difference() {
