Hey, I'm looking for an OpenSCAD design for a parametric drill bit carousel that mounts onto an Ikea Skadis pegboard. I've seen some similar designs online, but I'd like one that is fully customizable with specific parameters. I'm not looking to use any external libraries like MCAD or BOSL.

Here's what I need:

**General Shape & Dimensions:**
*   It should be a cylindrical carousel.
*   I need to be able to control the **radius** and the overall **height** of the carousel.
*   It needs a grip on the bottom for easy handling. I want to control the **frequency** and **amplitude** of those grip "waves" and also their **height**.

**Drill Bit Holes:**
*   The design needs to have a set of holes to hold drill bits.
*   I want to define the **drill sizes** through an array, and the holes should be sized accordingly.
*   The holes should also have a small edge around them. I need parameters to control the **edge width** and the **edge height**.
*   I want to specify the **spacing** between the drill holes as well as the spacing between the drill holes and the edge of the carousel.
*   I want to choose between `round` and `hexagon` shaped holes.
*   Optionally, labels next to each drill hole with their size should also be parametric. I'll need options to control the label **font**, **size**, and the label's **height** (to make it pop out from the body). I should also be able to pass in an array of strings to use for the labels, otherwise it will just use the drill sizes.
*   The number of holes should match the number of elements in the drill size array.

**Holder Base:**
*   The carousel needs an inset on the bottom to fit into a compatible holder (I'll provide the specs below).
*   I need parameters to set the **height** and **radius** of that base.
*   Similar to the drill holes, this inset should also have edges, so I'll need control over the **edge width** and **edge height**.

**Top Label:**
*   I want to add a text label on the top face of the carousel.
*   The text, font, size, and label height should be customizable.
*   I should be able to choose whether the label is **embossed** (raised) or **embedded** (engraved).
*  The label text should be rendered in either a **straight** line or on a **circular path** around the top of the carousel.
*   And finally I'll need a setting to adjust the **degree** span of the top label if it is on a circular path.

**Specific Parameters:**
*   **Body**
    *   `radius` (default: 25mm)
    *   `height` (default: 20mm)
*   **Grip**
    *   `freq` (default: 20)
    *   `amp` (default: 0.75)
    *   `grip_height` (default: 5mm)
*   **Drill Holes**
    *   `drill_style` (default: "round", options: "round", "hexagon")
    *   `drill_sizes` (default: `[4, 5, 6, 7, 8, 9, 10]`)
    *    `drill_labels` (default: `[]`)
    *   `drill_edge` (default: 1mm)
    *   `drill_edge_height` (default: 2mm)
    *   `drill_inner_spacing` (default: 0.2mm)
    *   `drill_outer_spacing` (default: 2mm)
*   **Drill Labels**
    *   `drill_label` (default: true)
    *   `drill_label_font` (default: "Liberation Serif:style=Bold")
    *   `drill_label_size` (default: 0.5)
    *   `drill_label_height` (default: 0.4mm)
*   **Holder**
    *   `holder_height` (default: 18mm)
    *   `holder_radius` (default: 4.825mm)
    *   `holder_edge` (default: 1mm)
    *   `holder_edge_height` (default: 2mm)
*   **Top Label**
    *   `top_label` (default: true)
    *   `top_lable_type` (default: "circular", options: "straight", "circular")
    *   `top_label_style` (default: "emboss", options: "emboss", "embedd")
    *   `top_label_text` (default: "Metall")
    *   `top_label_font` (default: "Liberation Serif:style=Bold")
    *   `top_label_size` (default: 3)
    *    `top_label_height` (default: 1mm)
    *   `top_label_degree` (default: 200)

Could you please provide the OpenSCAD code for this design? It's okay if it's multiple files. Thanks!

Hey, I'm looking for a way to generate some custom drawer pulls/knobs with labels, and I want it to be parametric in OpenSCAD. I'd like to be able to type in the text for the label, control its size, and also have an option to include a handle or not. I need it to be relatively easy to attach, like with a command strip.

Here's the gist of what I'm looking for:

*   **Label Text:** I need to be able to specify what text appears on the pull.
*   **Label Size:** I need to control the height of the text for the label. The width of the base should dynamically adjust to the length of the text.
*   **Handle Option:** I'd like an option to either include a handle or just have the label as a flat piece.
*   **Handle dimensions:** If the handle option is enabled, I need to have parameters to control the width, thickness and height of the handle, including a wider top section.
*   **Thickness:** Overall thickness of the label base needs to be controlled, as well as the handle if that option is used.
*   **Attachment:** I plan to use command strips or something similar to attach these to furniture, so the base needs to be flat.
*   **Material:** I'm planning on 3D printing these, so I need to keep the design print-friendly.

I think I need a main module that creates the label plate by extruding some text from a base and a separate module or set of modules to create the handle if the handle option is enabled. The label base should be a hull of a few cylinders, and the text needs to be centered. The handle should be two cubes combined using a hull, with an additional cube on top that's offset upward. I'd also like an option to add a little bit of extra 'meat' to the top of the handle, just as a style option that extends downward. I'm not sure if this should be another module, or part of an existing module. I guess the handle also needs to be scaled up a little bit before the negative space for the handle is subtracted.

Could you please provide an OpenSCAD file (or set of files) that can do this for me, with all those parameters? I'd like to be able to change all of the above settings, including the text and the handle on/off option. Also, make sure the code is well-commented so I can understand what's going on. Thank you!

Hey, I'm looking to create a parametric tool for laser cutter lens and mirror retaining rings using OpenSCAD. I've got a basic design in mind, and I need it to be flexible enough to handle different retaining ring sizes and tooth configurations.

The tool should basically be a cylinder with teeth that engage with the retaining ring. Here are the key parameters I need to control:

*   **`tooth_width`**: The width of each tooth that engages with the retaining ring.
*   **`tooth_height`**: The height of the teeth.
*   **`tool_diameter`**: The outside diameter of the main cylindrical part of the tool. This should match the inner diameter of the housing that holds the lens or mirror.
*   **`tool_height`**: The total height of the tool.
*   **`wall_thickness`**: The thickness of the tool's walls. I want it to be hollow inside.
*   **`4_teeth`**: A boolean flag. If true, the tool should have four teeth arranged in a cross pattern; otherwise, it should have two opposite teeth.
*   **`clearance`**: A small clearance value to ensure a good fit without being too tight.

I'd also like to have some knurling on the outside of the tool for better grip. It doesn't need to be super complex, just something that looks knurled and is controlled by a `knurl_count` and `knurl_d` parameters.

I'm thinking the main body of the tool should be a hollow cylinder, with the teeth extending from the bottom.  The knurling can just be some simple cylinders arranged on the outside body. I want to avoid using any extra libraries if possible and would prefer not to define a `preview` module.

Can you generate the OpenSCAD code for this tool? I need to be able to easily adjust these parameters in the customizer. Thanks!

I need a parametric OpenSCAD design for a hook that can hold a shower hose and be mounted to the wall. It should consist of a flat base plate and a hook extending from it.

Here are the key parameters:

*   **Base Plate:**
    *   `baseWidth`: Width of the base plate.
    *   `baseHeight`: Height of the base plate.
    *   `wallThickness`: Thickness of the base plate (and the hook itself).
*   **Hook:**
    *   `hookWidth`: Length of the hook (how far it extends from the base).
    *   `hookOpenAngle`: The angle of the hook opening – how much it curves outwards.
    *   `hoseDiameter`: The inner diameter of the hook to accommodate the hose.
*   **Printing:**
    *   `printOnSide`: An angle to rotate the entire object for printing, either flat on the base (`0`), or 90 degrees rotated for printing with supports (which is probably a better idea, structurally). I'd like this to be an option - we don't need to bake it into the default design.

I'd prefer a design that's easy to customize, with all of these parameters editable in the Customizer. I was thinking of something like the attached example, but I need it from scratch, not modified.

Could you please generate an OpenSCAD file for this, making sure the parameters are well-named and the design is easy to understand? No external libraries are needed for this design, I believe.

I'm looking to create a guitar pick holder, and I have a specific design in mind based on a guitar shape. I'd like it to be parametric so I can easily adjust the size and other features.

Here's the breakdown of what I want:

**Overall Shape:** The holder should be shaped like a stylized guitar body. It doesn’t need to be super detailed, but should have the general outline of a guitar, with the main body section and a slightly more narrow "neck" area.

**Two Parts:** I need two main parts, the base (or body) and a lid.

**Base (Body):**
*   **Walls:** The base should have walls of a consistent thickness all the way around the guitar shape.
*   **Inner Bump:** Inside the base, I'd like a raised bump or ridge in the center. This isn't for storage, but to make the picks easier to grasp and pull out. I'd like this bump to be adjustable via parameters - specifically its height and placement.

**Lid:**
*   **Fitting:** The lid should fit snugly onto the base.
*   **Depression:** The lid should have a depression on the top that could hold a couple of picks that you're actively using. This depression should be circular or slightly oval, and I'd like to be able to adjust its size and depth.
*   **Clear Effect:** I'm planning on printing the lid with a low infill so it will be slightly transparent, so I don't need any internal structures to be visible on the outside.

**Parameters:** I'd need to be able to adjust these parameters:
*   `R1`: Overall radius or size of the "body" part of the guitar shape.
*   `R2`: Radius for the "neck" or tip of the guitar shape.
*   `H`: Overall height of the base/body section.
*   `T`: Wall thickness of both base and lid.
*   `bump_height`: Height of the bump inside the base.
*   `bump_offset_x`: Position of the bump along the x axis.
*   `depression_radius`: Radius of the depression in the lid.
*   `depression_depth`: Depth of the depression in the lid.

**OpenSCAD:** Please generate the design using OpenSCAD. I don't have any specific requirements for libraries you must or must not use, but it might be worth checking out the MCAD library if it has any relevant shapes.

I think that's everything. Let me know if you have any questions.

Hey, I'm looking to generate a customizable coniferous tree for 3D printing, similar to the one I saw online. It should be parametric, allowing adjustments to the overall height, trunk and branch dimensions, and the number of branches. I want it to have a distinct trunk, branches that increase in length moving away from the tip, and a base for stability. I'm thinking of something that uses cylinders and rotations, probably. I'm comfortable using OpenSCAD, but I need the files.

Specifically, here are the parameters I would like to be able to control:

*   **Overall Height:** The total height of the tree.
*   **Trunk Diameter:** The diameter of the base of the trunk.
*   **Trunk Height:** The height of the trunk before the branches start.
*   **Tip Height:** The distance from the top of the tree where the branches start.
*   **Tip Diameter:** The diameter of the very top of the tree.
*   **Minimum Branch Length:** The shortest possible length of the branches.
*   **Maximum Branch Length:** The longest possible length of the branches.
*   **Number of Branch Rings:** The number of rings or layers of branches on the tree.
*   **Minimum Branches Per Ring:** The minimum number of branches in a ring.
*   **Maximum Branches Per Ring:** The maximum number of branches in a ring.
*   **Base Diameter:** The diameter of the base of the tree.
*   **Base Height:** The height of the base of the tree.
*   **Branch Diameter:** The diameter of the cylindrical branches.
*   **Branch Length Randomness**: It would be great if there was some randomness applied to the branch length, with parameters for minimum and maximum random trim applied to the branch length.
*   **Branch Angle Randomness:** Similarly, some random rotation applied to each ring of branches would be great, within a configurable range.

I’d like the branch lengths to vary, increasing in length from top to bottom, and also for the number of branches per ring to increase moving away from the tip. The code would need to calculate the branch length and spacing for each ring, based on the provided min/max values.

I am not using any external libraries for this, just stock OpenSCAD.

Can you generate the OpenSCAD file(s) for me? Thanks in advance!

I'm looking to create a customizable, indexed folding leg system for a quadcopter, similar to the design described in the included OpenSCAD file. I need an OpenSCAD design that allows for parametric adjustment of all the key dimensions. I'd like to control the leg length, leg foot radius, and the thickness of the leg walls. The pivot system should be adjustable in terms of the inner and outer pivot radii and thicknesses, the clearance between the pivots, the pivot hole diameter, and the offset of the pivot hole relative to the interlock blocks.

The leg should lock into both the extended and folded positions using a detent mechanism, and I need to be able to customize the detent bump length and width, the clearance between the bump and slot, as well as the clip lever length and thickness and the spring's parameters, such as clearance width, span angle, and gap width. The design should also include a customizable mounting plate thickness.

The layout should allow for three different views - Design (parts spaced for easy editing), Print (parts arranged for printing, potentially with mounting plate rotated), and Exploded (parts separated to see how they connect). All three should be easy to toggle between via a single layout parameter.

Could you please generate the OpenSCAD code for this? I do not need any of the code from my existing .scad file. Please use the following libraries in your design: MCAD, BOSL.

I'm looking to create a parametric bench dog for woodworking. I need an OpenSCAD design where I can easily adjust the dimensions.

Here's what I have in mind, based on my current design, but I want the AI to generate it from scratch:

*   **Core Body:** It needs a cylindrical body that fits into a dog hole. The key parameter here is the **Hole_diameter** which will dictate the size of the hole the dog fits into.
*   **Shaft Height:** The portion of the dog that sits inside the dog hole needs to have a configurable height: **Body_height**.
*   **Top Flange (Head):** Above the dog hole, I want a flat, circular flange or "head" to rest on the benchtop. The height of this flange above the bench surface will be **Head_height**.
*   **Flange Diameter:** The flange needs to extend out from the central cylinder. The extension distance will be controlled by **Protrusion** and additionally offset slightly (controlled by a **Percentage_protrusion** parameter related to the head height).
*   **Angled Underside:** To ensure good grip, I'd like the bottom edge of the flange (where it meets the body) to be angled slightly towards the shaft.  I was calling this offset "offset" calculated from Head_height, but you should make sure it's parametric.
*   **Bevel:** A small bevel at the very bottom of the cylinder is ideal, to ensure it slides in easily.  I called that "smusso".
*   **Fillet:** A small fillet or chamfer between the cylinder body and flange would be nice. I had a variable called 'lasco' for that, you can call it whatever makes sense to you.

I want to control all of these parameters:
*  `Head_height` - Height of the head above the surface
*  `Body_height` - Height of the shaft within the dog hole
*  `Hole_diameter` - Diameter of the cylindrical shaft
*  `Protrusion` - Radius distance the head extends past the shaft
*  `Percentage_protrusion` - Percentage of the head height that the head underslide is inset
* `lasco` - the radius of the fillet between the body and head
*  `smusso` - the bevel at the bottom of the body

I'd like a single `.scad` file for this. Please make sure all the parameters are well-documented and easy to modify. I don't think I need to use any external libraries for this, do you?

I'm looking for an OpenSCAD design for an SMD component organizer, similar to the one described in the file I've attached. Here are the key features I want:

*   **Circular Layout:** The organizer should be circular with a central hub and multiple radial sections.

*   **Parametric Dimensions:** I need to be able to adjust the following parameters:
    *   `capDiameter`: The overall diameter of the organizer.
    *   `height`: The overall height of the organizer (excluding any border).
    *   `sectorCount`: The number of compartments around the circle.
    *  `radialSections`: The number of concentric divisions within each sector to make a grid
    *   `parkSectorAngle`: The angle of an optional "parking" sector, which can be automatically calculated or set manually.
    *   `capThickness`: Thickness of the cap.
    *   `capHoleDiameter`: Diameter of the center hole in the cap.
    *   `washerDiameter`: Diameter of a washer piece
    *   `washerThickness`: Thickness of the washer
    *  `washerPoleDiameter`: Diameter of a pole on the washer to connect to the cap
    *  `washerPoleHeight`: Height of the pole on the washer to connect to the cap
    * `washerScrewDiameter`: Diameter of the screw head or other protrusion on the washer
    *   `washerScrewHeight`: Height of the screw head or other protrusion on the washer
    *   `washerScrewType`: Type of screw head (cone or flat).
    *   `centerDiscRadius`: Radius of the central disc at the bottom of the organizer.
    *   `outerWallThickness`: Thickness of the outer wall
    *   `wallThickness`: Thickness of the compartment walls.
    *   `floorThickness`: Thickness of the floor of the organizer.
    *   `heightDiff`: Height difference between the center of the organizer and the outer edge, for a slightly conical design.
    *    `borderThickness`: Thickness of the border
    *    `borderHeight`: Height of the border.
    *   `screwHoleDiameter`: Diameter of the screw hole.
    *  `stickerThickness`: Thickness of the sticker.
    *  `capGap`: The gap between the cap and the border
    *   `capPoleGap`: The gap between pole on the main body and cap hole.
    *   `capCross`: Thickness of the edge of the cap on the outer wall.
    *  `fn`: Smoothness of circles (number of faces in a cylinder).

*   **Compartment Calculation:** The compartment areas should be calculated to be approximately equal, based on the `sectorCount` and `radialSections` parameters.

*  **Washer:** Include a separate module to generate a washer that fits to the bottom of the cap, with adjustable dimensions.

*   **Stackable:** I want the design to be stackable. It looks like a slightly raised outer edge with a border at the top would accomplish this.

*  **Sticker:** Include a separate module to generate a sticker to use as a label. This isn't critical, and it's not clear how easy to print it would be, so it can be lower priority.

*   **Output:** I want to be able to export the main organizer, the washer, and the sticker separately as STLs, so it seems like having `part` as a variable to select the output is helpful.

I don't need any libraries other than the built-in OpenSCAD libraries, I think.

I need a parametric OpenSCAD design for a wall-mounted hanger, primarily for headphones or hats. I've got a good idea of what I want but need help with the implementation.

The main support should be a curved arm that extends out from the wall, with a rounded shape to cradle the item. I want to be able to adjust the radius of this curve to fit different objects, so that's the primary parameter. I'd also like it to have a flat mounting plate that scales based on this radius. This plate will be stuck to the wall with double sided foam tape.

I was thinking a quarter-circle shape for the arm, and it should have a slight cutout on the underside near the mounting plate to reduce the material needed. And the plate itself should be a rectangle, slightly larger than the circle radius. I need this to be fully parametric with the ability to control the curve radius, and I also want to be able to change the resolution of the curves via `$fn`.

Can you please generate the OpenSCAD code for this?

I'm looking to design a magnetic knife strip, and I'd like to make it parametric so I can easily adjust it for different magnet sizes. I'll be using neodymium magnets, and I want to be able to adjust the length, width, and thickness of the magnet pockets, as well as the overall thickness of the back, sides, and top of the strip. I would also like to have two countersunk screw holes on the strip to mount to the wall.

Here's a breakdown of what I'm envisioning:

*   **Magnet Pockets:**
    *   `magnetx`: Total length of the magnets placed end-to-end.
    *   `magnety`: Total width of the magnets. I expect to put magnets side-by-side as well as end-to-end.
    *   `magnetz`: Thickness of the magnets.
    *   These should create a channel for the magnets to sit in, with a solid back, and an open top which will be covered by the top of the knife strip.

*   **Knife Strip Structure:**
    *   `thickness`: Thickness of the top piece.
    *   `backthickness`: Thickness of the back piece.
    *   `sidethickness`: Thickness of the side pieces.
    *   `sidemargin`: How far the side pieces are from the edge of the magnet pocket, on both sides.

*   **Screw Holes:**
    *   Two countersunk screw holes placed symmetrically along the length of the strip. I would like to be able to specify the diameter of the screw hole and the countersunk part individually, and I would like a parameter specifying the depth of the countersink.

I'd like the design to be a single piece with the magnet pockets and structural components all unified. The screw holes should extend through the back and countersunk on the side that will be facing the wall.

Could you generate an OpenSCAD file for this?

I need a parametric design for a replacement strap for my Nalgene bottle, similar to the one I made before, but this time I'd like to be able to customize it for different bottles. I'm thinking of designing it to be printed in flexible materials like TPU or PETG, so it needs to be robust but still have some give.

The basic concept is a flat strap with circular cutouts at either end that fit around the bottle's neck and cap. Here are the key parameters I need to be able to adjust:

*   **`strap_thickness`**: The thickness of the strap (e.g., 1.75mm)
*   **`strap_width`**: The width of the strap (e.g., 10mm)
*   **`strap_length`**: The length of the strap (e.g., 105mm). This is the length of the straight part of the strap, *not* including the curved parts at the ends.
*   **`bottle_outer_dia`**: The outer diameter of the bottle's neck where the strap attaches (e.g., 65mm).
*   **`bottle_inner_dia`**: The inner diameter of the bottle's neck where the strap attaches (e.g., 55mm).
*  **`cap_outer_dia`**: The outer diameter of the cap where the strap attaches (e.g., 30.5mm)
*   **`cap_inner_dia`**: The inner diameter of the cap where the strap attaches (e.g., 13.7mm)
*  **`bottle_fillet_pitch`**: This is a small piece to add some clearance at the bottle, I guess you could think of it as the "pitch" of a fillet that goes around the circumference of the inner diameter of the strap, where the strap meets the bottle neck (e.g., 2mm)
*   **`bottle_fillet_depth`**:  The depth of the bottle fillet, extending radially inward into the cut-out (e.g., 2mm).
*   **`cap_fillet_pitch`**: Same as `bottle_fillet_pitch`, but for the cap end (e.g., 2mm)
*   **`cap_fillet_depth`**: Same as `bottle_fillet_depth`, but for the cap end (e.g., 4mm)

The "fillets" should be small cutaways, shaped like a section of a rounded, flattened cylinder, that provide a little clearance. They should go around the inside edges of the strap's openings at the bottle and the cap. They help a little with installation and also with ensuring a tight fit in PETG, where things tend to shrink slightly.

I need the whole design to be a single object in the end, so I can print it in one go. I'm looking for a design that's easy to adjust and generate for various bottles and caps, so having it parametric would be amazing. I don't need anything fancy.

Could you provide the necessary OpenSCAD code for this? I'd like to generate a 3D model without extra libraries if possible.

I'd like to create a customizable R-hop jig for cutting R-hop patches from silicone tubing. I need it to be parametric so I can adjust it to different barrel and tubing sizes, as well as blade thicknesses.

Here are the parameters I need to control:

**Basic Parameters:**

*   `Inner`:  The inner diameter of the silicone tube. I'll start with 6.1mm but it should be adjustable.
*   `Outer`: The outer diameter of the silicone tube, something like 9.7mm initially, but adjustable as well.
*   `a`: The initial depth of the cutting window. I'm thinking around 0.75mm to start but I will want to create a few at different depths at once.
*   `b`: The thickness of the blade I'll be using. I use 0.45mm but it must be editable.

**Array Size Parameters:**

*   `n`: The number of jigs in a single row. This will let me create multiple jigs at once with increasing window depths. The default should probably be 1.
*  `m`: The number of rows to make. Not likely I need more than 2. Default 1.
*   `da`: The increment in depth for the cutting window for each additional jig in a row. I think a 0.15mm step would be useful initially, but this should also be configurable.

**Advanced Parameters:**

*   `h`: The height of the jig. I'd like this to be adjustable, starting at 20mm.
*   `t`: The wall thickness of the jig, allowing me to adjust its stiffness. Default 2mm.
*   `Base`: The size of the base for the jig. 6.3mm seems good for now but this should be editable.
*   `Chamfer`: A boolean option to add chamfers to the jig's cutting edges. It should default to "Yes".
*   `Angle`: If chamfers are enabled, I need an angle parameter. 60 degrees seems right for now.
*   `Length`:  If chamfers are enabled, I need the length parameter. Maybe 0.8mm to start.
*   `Radius`: A radius for rounding the base corners. I should be able to turn this off by setting it to 0 and should default to 5.
*   `Indicator`: A boolean parameter that adds a small mark to the jig with the smallest window cut to visually indicate the smallest cut jig when creating an array. Default value should be "No", because it can interfere with printing if only one jig is used.
*   `Quality`: a variable to change $fs and $fa of circular shapes to impact printing performance of non-relevant shapes - should default to 90.

The design should have a cylindrical inner shape that matches the inner diameter, and a cylindrical outer shape that matches the outer diameter, with a rectangular cut-out for the cutting window. If I'm making multiple jigs, the cut-out should be offset incrementally. I'd also like a base that connects all of the jigs together and for the base to have rounded corners based on the `Radius` variable.

Could you generate an OpenSCAD file (or files) that would allow me to create this design? Make sure to use the parameters I listed above! I do not have any libraries installed so you will need to include all the necessary code in the generated file(s).

I'm looking to design a control panel for a K40 laser cutter, and I want it to be fully parametric, so I can adjust component positions easily. I've got a basic idea of what it should look like. It'll have cutouts for an LCD screen, a potentiometer, an ammeter, two switches, a button, and a voltmeter. I also need mounting posts at the corners and for the LCD.

Here's how I envision the panel's construction: It should be a flat plate with cutouts for the components. The positions of these cutouts should be adjustable using parameters, so I don't have to manually change the measurements for each component every time. I would also like to have the option to see the outline of the panel or the actual 3d model, based on a `STL_ready` variable. If `STL_ready` is true, I just need the basic panel with holes and posts; if it's false, the panel itself should be represented as a thin plate, and the areas around the holes should have a slightly extruded square around each.

I'd like you to create an OpenSCAD file that takes the following parameters:

*   **Panel Parameters:**
    *   `thickness`: The thickness of the panel.
    *   `STL_ready`: A boolean flag to switch between showing the 3D model or a 2D representation with extrusions.

*   **LCD Parameters:**
    *   `LCD_x`: X-coordinate of the LCD center.
    *   `LCD_y`: Y-coordinate of the LCD center.

*   **Potentiometer Parameters:**
    *   `POT_x`: X-coordinate of the potentiometer center.
    *   `POT_y`: Y-coordinate of the potentiometer center.

*   **Ammeter Parameters:**
    *   `AMP_x`: X-coordinate of the ammeter center.
    *   `AMP_y`: Y-coordinate of the ammeter center.

*   **Switch 1 Parameters:**
    *   `SW1_x`: X-coordinate of the first switch center.
    *   `SW1_y`: Y-coordinate of the first switch center.

*  **Switch 2 Parameters:**
    *  `SW2_x`: X-coordinate of the second switch center.
    *  `SW2_y`: Y-coordinate of the second switch center.

*   **Button Parameters:**
    *   `BTN_x`: X-coordinate of the button center.
    *   `BTN_y`: Y-coordinate of the button center.

*   **Voltmeter Parameters:**
    *   `VOLT_x`: X-coordinate of the voltmeter center.
    *   `VOLT_y`: Y-coordinate of the voltmeter center.

The file should create the panel with all the cutouts. It also should generate mounting posts that are 6mm in diameter with a 3mm diameter through-hole for the LCD posts, and the voltmeter mounting posts should be 6mm with 2mm hole. The panel should also include four mounting posts at each corner with 6mm diameter posts and 5mm holes

Make sure you use the `difference()` function to cut out all the holes so that the final result is a solid panel with empty areas where the parts should be mounted. I think it would be helpful if you break up each element into its own module, to improve the readability of the code, and make it easier to adjust individual elements.

I would also like you to use `$fn=60` in all cases when using circles. Please also use the `linear_extrude` function to create cutouts and posts. I think that should be all. Let me know if you have any questions.

I'd like to design a customizable insert for Sortimo-style boxes. The basic idea is a container with a sloped side wall, with customizable dimensions and a few other features.

Here's what I'm thinking:

**Overall Shape:** The insert will be a box with a rectangular base, but the side walls won't be vertical. Instead, they will be sloped inward from the base to a smaller rectangle at the top. This creates a kind of trapezoidal cross-section on all four sides.

**Parameters:**

*   `x`: Integer - number of modules wide (each module will be 52mm)
*   `y`: Integer - number of modules long (each module will be 52mm)
*   `height`: Height of the container in mm.
*   `thick_wall`: Thickness of the side walls
*   `thick_base`: Thickness of the base
*   `side_high`: How far the top edge of the sloped walls are recessed from the edge.
*   `side_low`: How far the bottom edge of the sloped walls are recessed from the edge.
*   `diff_high_low`: The difference in recession between the top and bottom of the slope. The bottom is further recessed by half of this.

**Details:**

*   The overall width should be `x * 52`, and length should be `y * 52`.
*   The sloped walls transition smoothly from the outer edge of the base to the smaller rectangle at the top.
*   The bottom edges of the slope are offset from the base edges by `side_low + (diff_high_low / 2)`, and the top edges are offset by `side_high`.
*   The walls and base should have the specified `thick_wall` and `thick_base` thicknesses respectively.
*   There should be four small circular holes, with a diameter of 3mm, centered 5mm in from the corners of the bottom face (offset by the recession).

**Libraries:** I'm not expecting any external libraries for this, just standard OpenSCAD features.

I'd like the code to be well structured with modules, and be fairly clear and easy to read. The design should also be parametric, so I can change the parameters and generate different sizes and shapes.

Could you generate the OpenSCAD code based on these requirements? I'm looking for a single .scad file. Thanks!

Hey, I'm looking to generate an end cap design for a tube, and I've got some specific parameters I need to control. I need an OpenSCAD file, or possibly multiple files if that makes sense.

The basic idea is that I have a tube with outer dimensions I need to match, let's call them EDmX and EDmY for the horizontal and vertical dimensions, respectively. Then there's the wall thickness of the tube itself, Tkt.

The end cap needs to have an insert that fits *inside* the tube, and that insert should be LnIn long. This insert also has a "gripper" system on the sides to hold it in place inside the tube, and it also needs an outer cover, so that it creates a kind of closed end for the tube. The cover should have a thickness of Tke. The grippers have a size or height, Gp, and a thickness of GpT.

Basically, what I'm envisioning is a rectangular (or squarish) end cap that slides inside a tube and then has an external cover. The gripper should be sort of a ribbed design, that is repeated at intervals along the length of the insert, and the outer cover needs to be blended to the edges of the insert.

I need to be able to adjust all these dimensions:

*   **EDmX**: External dimension on X direction (horizontal)
*   **EDmY**: External dimension on Y direction (vertical)
*   **Tkt**: Tube wall thickness
*   **LnIn**: Length of the insert that goes into the tube
*   **Tke**: Thickness of the external cover
*   **Gp**: Gripper size/height
*   **GpT**: Gripper thickness
*   **Resolution** ($fs) - should be easily adjustable.

I'd like the resolution to be controlled with the `$fs` variable so that I can adjust the quality of the generated mesh. I'm guessing something around `$fs = 0.1` is a good starting point.

Can you generate the OpenSCAD code for this? I'd prefer it to be parametric and easy to adjust via customizer. Also, could you include some comments that help me understand what's going on?

Okay, I'd like to commission a parametric OpenSCAD design for a customizable name tag keyring, but also with a cable slot so it can snap onto a lighting cable. I'm aiming for something like what's described below, but I need the AI to generate the SCAD code from the ground up; I don't want it to tweak my code.

Here's the breakdown of what I want:

**Core Functionality:**

*   **Text-based Keyring:** It should generate a name tag/keyring based on user-provided text.
*   **Font Selection:** The user needs to be able to pick a font for the text. I'd like the fonts in the standard OpenSCAD text() function, like "Lobster," "Anton," etc to be available as options.
*   **Letter Spacing & Height:** Each letter should have its own adjustable space relative to the preceding letter, and also its own height. I need this because I want to make an effect that is slightly wave-like.
*   **Twist:** The entire name tag should be able to have a twist applied to it. I want to be able to specify the angle and the center of the twist.
*   **Cable Slot:** There should be an option for a cable slot, which is essentially a cylindrical void that can be adjusted. I need it to cut through a portion of the main body.
*   **Optional Loop:** I'd like to add the option for a small loop at one end, using a single letter.
*   **Loop Font:** A specific font can be selected for the loop itself.
*   **Overall Rotation:** Finally, the entire design should be rotatable for preview purposes

**Specific Parameters:**

*   **Text & Font:**
    *   `Font_name`:  Dropdown list of fonts (e.g., "Lobster," "Anton," etc.)
    *   `Text`: Text input for the name/word.
    *   `Rotation`: Rotation angle of the preview (0-360 degrees)
*   **Letter Spacing & Height:**
    *   `letter_1_height` to `letter_9_height` (adjust height of the letters),
    *    `letter_2_space` to `letter_9_space` (adjust horizontal spacing between letters)
    *   Note that there should be a default offset of zero for the first letter.
*   **Twist:**
    *   `twist`: Angle in degrees for the twist.
    *   `center`: Center of the twist.
*   **Loop Settings:**
    *   `Loop_x_position`: Horizontal position adjustment of the loop.
    *   `Loop_y_position`: Vertical position adjustment of the loop.
    *   `Loop_character`:  Text input for the loop character. Leave blank for no loop
    *    `Loop_font`: Dropdown list of fonts for the loop.
*   **Cable Slot:**
    *   `CableSlot`: A boolean for enabling or disabling the cable slot.

**Important Notes:**

*   Please make sure the parameters are well-commented in the SCAD code so I understand how it works.
*   I'm not looking for existing library dependencies or external code. I need this generated from the ground up.
*   I want to be able to edit all of the values of spacing and height for the individual letters, rather than have them tied to an overall setting or a scale.
*   I'm aiming for fine granularity on the height and spacing parameters – fractions of a mm are essential.
* The cable slot is for a standard USB cable, so the default needs to be sized accordingly.

I know it's a big ask, but I think it would be a really useful tool. Thanks in advance for your work.
