I want to create a parametric, custom-fit flip-flop design using OpenSCAD. I'd like to be able to define the overall shape of the sole using a series of Bezier curves, with control points to fine-tune the shape. I need to specify the fixed points along the contour, the control points for each Bezier curve, and the thickness of the sole.

Specifically:

*   **Sole Shape:** The sole should be defined by a series of connected Bezier curves. I've provided the fixed points (P01-P08) and control points (CT01-CT08). Each segment of the sole edge should be a 2D Bezier curve.
*   **Thickness:** I need a parameter to control the sole's thickness.
*   **Left/Right Version:** A parameter to create a left or right version of the flip-flop (mirroring the design).
*   **Drainage Holes:** I'd like to add drainage holes to the sole. These holes should be cylinders and be positioned in a grid. Parameters to control hole size, shape (number of sides), rotation, the type of pattern, and offsets for X, Y, and Z positioning should be included. I need to be able to have the holes on the top only, or on both top and bottom.
*  **Laces:** There should be an option to include the anchors for the laces, and also to control each lace's X and Y position, and its rotation. Each lace anchor should be comprised of a base, and an extruded section that attaches the string to the flip flop.
*   **Edit Mode:** I'd like a way to visualize the control points and tangent lines during the design process, as well as the start and end points for each curve. This should be a toggleable "edit mode".
*   **Visualization:** I would like markers placed along the outside edge of the flip flop at regular intervals so that I can visually determine where the design will be cut out.
*  **Resolution:** I need a parameter to control the curve resolution.

Could you generate the OpenSCAD code for this? I do not need any external libraries for this design.

I'm looking to create a parametric nozzle plate for M6 nozzles, similar to the one I found on Thingiverse. I need it to be customizable in terms of the number of nozzles and have some text on it to identify the material. Basically, it's a rectangular block with holes for the nozzles and some raised text on top.

The original design had a few limitations, like not working correctly with numbers in the text and not functioning in online OpenSCAD customizers. I'd like to avoid those problems if possible.

Here are the specific features I need:

*   **Nozzle Holes:** The design should accommodate M6 nozzles (6mm diameter), arranged in a row. The number of nozzles should be a parameter I can adjust, from 1 to 6. I guess I need clearance, so maybe 6.5mm diameter for the holes. I also need to be able to position those holes.
*   **Text:** There should be an area for text, to identify the filament material like "PLA," "PETG," etc. This text should be configurable and should be raised from the surface of the plate. I don't want it to be knocked out like the thingiverse reference design, I want it to be printed. I would like to select the font and size. I want to be able to place the text anywhere on the block.
*   **Plate Size:** The overall plate dimensions need to scale with the number of nozzles and text length, but should have some adjustable parameters for width, height and thickness. I'd like the main body to be rectangular with rounded edges.
*   **Rounded edges**: All the external edges should be rounded for aesthetic reasons.
*   **Customizability**: Everything should be easily configurable through parameters (number of nozzles, material text, font, size of text, dimensions of the plate)
*   **OpenSCAD**: The design should be created in OpenSCAD and use standard modules where appropriate.
*  **Compatibility**: The design needs to work in the online OpenSCAD customizer.

I'm not too familiar with the various libraries available for OpenSCAD, but I'm aware that there are some good ones for more advanced functions. I'm open to using libraries like MCAD or BOSL2 if they're helpful for implementing this. Specifically, if there is an efficient way of rounding the edges other than using `minkowski`, I'd like to use that.

Could you provide me with the OpenSCAD file(s) to accomplish this?

Hey, I'm looking to create a customizable spinning top generator in OpenSCAD. I have a basic idea in mind, but need help making it parametric.

Essentially, the top should have a central hub with a customizable number of "petals" extending outwards. The hub itself should be a rounded cylinder, and there should be a hole through the center of the top for a separate stick.

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

*   **Number of Petals:** This should be a whole number that determines how many petals the top has (e.g. 3, 6, 10, etc.)
*   **Petal Shape:** I'd like to be able to choose between at least three different petal profiles:
    *   *Quadratic*: The petals have a curved shape that sort of follows a quadratic equation, bowing inwards a bit.
    *   *Square*: The petals have a simpler, more 'square' profile.
    *  *Linear/Straight*: The petals are created by lines, straight and not curved.
*   **Petal Block Size:**  Petals are constructed from segments, and I want to adjust the width and height of these segments independently.
    *   *Block Width*: width of each petal block.
    *   *Block Height*: Height of each petal block.
*   **Hub Radius:** The radius of the main cylindrical body of the top.
*   **Hole Radius:** The radius of the hole in the center of the top for the stick.
*   **Tip Radius:** The radius of the rounded tip at the bottom of the hub and the top.
*   **Hub Height:** The overall height of the main hub (cylindrical part) of the top.
*   **Number of Petal Blocks:** The length of each petal in terms of the number of building blocks.
*    **Stick Height**: The height of the removable stick.
*   **Stick Radius**: The radius of the removable stick, should be smaller than or equal to the hole_radius
*   **Rounded Stick**: Boolean value to define if the stick end should be rounded or flat
*   **Stick position x**: x-coordinate of the removable stick.
*   **Stick position y**: y-coordinate of the removable stick.

The petals should be created by a *hull* operation. The main body should be created using a *difference* operation between a union of hub elements and a cylinder to create the hole. The stick should be a cylinder, optionally with a sphere on the end.

Can you help me generate an OpenSCAD file or set of files that can handle all this? I think that's all I need, let me know if you need more info. Thanks!

Hi, I'm looking to create a parametric picture frame generator using OpenSCAD. I'd like to have a few different frame profiles to choose from, and the ability to customize the inner dimensions of the frame.

Specifically, I envision something like this:

*   **Frame Profiles:** I'd like to be able to choose between at least three different frame profiles. I have the profiles designed as 2D DXF files, so the design should be able to import those. Let's call them `section1.dxf` (a classical style), `section2.dxf` (a gallery style), and `section3.dxf` (a modern style).
*   **Inner Dimensions:** The user should be able to specify the inner width and height of the frame in millimeters. I'd like to set defaults and a range, like, say, 80 mm for both width and height, and a range of 0 to 200 mm for both.
*   **Part Selection:** The user should be able to choose to generate the whole frame, or just a single vertical or horizontal border. This will be helpful for 3D printing.
*   **Decorations:** I'd like each profile to have some unique decorations, which should also be parametric.
    *   For the `section1.dxf` (Classical) frame, I'd like to add some small spheres along the inside edge. The user should be able to set the distance from the edge, the height of the spheres, and the sphere diameter. Let's set the default to `[3, 2, 3.5]` for x, y, and diameter, respectively.
    *   For the `section2.dxf` (Gallery) frame, I'd like to add some small notches along the inside edge. Again, the user should be able to specify distance from edge, height, and length of these notches. A good default might be `[26.5, 10, 5]` for x, y, and length.
    *   The `section3.dxf` profile will not have any decoration for now.
*  **Assembly:** When printing separate borders, I'd like to include small alignment pins to help assembly. There should be pins on both the vertical and horizontal pieces. The location of these pins, as well as the diameter should be parametric as well. Let's set the default to `[15, 4, 1.75]` for the classical profile, `[15, 3, 1.75]` for the gallery profile, and `[10, 3.5, 1.75]` for the modern profile, in terms of x, y, diameter.

I'm hoping to have it create the frame by using linear extrusion and then combining the parts together. I think that should work?

I think that's about it. Let me know if you need any more info.

Hey, I'm looking to create a simple, printable funnel in OpenSCAD, and I'd love some help designing the code. Here's what I have in mind:

**Core Structure:**

*   **Funnel Body:** The funnel will have a main body consisting of three parts - a rim (the top wide part), a stem (the narrow tube at the bottom), and a conical section connecting them.
*   **Rim:** This will be a cylinder at the top of the funnel.
*   **Stem:** This will be another cylinder at the bottom, narrower than the rim.
*   **Conical Section:** This angled section will smoothly transition from the rim diameter to the stem diameter. It should have a user-adjustable angle.
*   **Wall Thickness:**  I need control over the wall thickness of the entire funnel.

**Parameters:**

I need to be able to easily adjust these dimensions:

*   `StemOD`: Outer diameter of the stem (the narrow part).
*   `StemZ`: Length of the stem.
*   `RimOD`: Outer diameter of the rim (the wide top part).
*   `RimZ`: Height of the rim.
*   `T`: Thickness of the funnel walls (should be consistent throughout).
*   `Slope`: Angle of the conical section, in degrees.

**Additional Features:**

*   **Tapered Tip:** I'd like a slight taper on the very end of the stem. Nothing fancy, just a simple taper to make the flow a bit better.
*   **Hidden Seams:** I'd like the layer start point to be in a not-so-obvious location to make 3D printing look better. I think this can be done by rotating the whole funnel slightly.

**Libraries:**

I'm not sure if there are any libraries that would be helpful with this design, but if there are any that might simplify the design or make it more robust, feel free to include them. I don't need specific .scad files; just point me to the names of libraries you think would be helpful, and I can make sure I have them installed.

The design should be as straightforward and easy to print as possible.

Thanks for your help!

I'd like to design a customizable license plate tag that can be attached to the bottom of a standard U.S. license plate. I want it to have a few specific features and be highly customizable.

First, the basic shape should be a flat rectangular plate with two rounded-off corners. I would like there to be cutouts in the plate so that the screws securing the license plate itself do not interfere with the tag. These cutouts should be placed in a way that accommodates typical license plate screw hole placements. I think some rounded features and chamfers on the edges would also be good.

Second, I want to add text to the tag. This text should be customizable, of course, with controls for both the content of the text and the font used to render it. I also need to be able to control the text's extrusion thickness, as well as its horizontal position on the tag, so it can be centered correctly depending on the text's length.

Third, I'd like the design to be parametric. I want to be able to change the overall size of the tag (length, width, and thickness), the radius of the rounded corners and chamfer, the depth and diameter of the cutouts, and the placement of the text (both vertical and horizontal). The text parameters should include font selection, size, offset and extrusion depth, as I described above. It would be great if all of this is adjustable via the customizer.

I think it would be useful if the cutouts used to accommodate license plate screws were themselves parametric (like diameter and depth) and if there was a way to specify the location of the first cutout using parameters (e.g., an x and y offset from the left edge) as well as a distance from the first cutout to the second cutout.

I'm hoping to use this design for 3D printing, so I would prefer it to be as simple as possible for printing. No complex overhangs and a general ease-of-printing approach.

I'd prefer it if the design doesn't rely on any external libraries, to keep things simple. I think this should be doable with standard OpenSCAD functions. I'm hoping to use it for multi-color printing on a Prusa, so a layer change parameter for dual color printing would be a nice touch. Thanks!

Hi there!

I'm looking to create a design for a small, decorative piece with embedded magnets. I've got the basic STL model of a dragon, called "Luci.stl," which I downloaded from Thingiverse. I need to modify this model by adding cylindrical holes to embed two magnets.

Here are the specific requirements:

*   **Base Model:** The design starts with importing the "Luci.stl" file. I can handle providing that, but your SCAD code will need to be able to import it.
*   **Magnet Holes:** I need to create two cylindrical holes within the model.
    *   **Magnet 1:**
        *   Diameter: 10mm
        *   Height: 2mm
        *   Position (relative to the center of the imported STL): x = -2mm, y = -4mm, z = 0.  (The z value is zero because the holes should be on the surface.)
    *   **Magnet 2:**
        *   Diameter: 10mm
        *   Height: 2mm
        *   Position (relative to the center of the imported STL): x = 19mm, y = 45mm, z = 0
    *   **Hole Depth:** The holes should actually be slightly deeper than the magnets, so they can be inserted easily (and to give a little wiggle room for printing).  I think making them 2.1mm deep would work.
*   **Parametric Design:** I'd like to make this design fully parametric, so I can easily change the magnet dimensions, positions, and even the resolution of the circles/cylinders if needed. The more parameters the better!
*   **Orientation:** The final output should be rotated by 180 degrees around the Y-axis (to flip it for better printing), so the final rotation is `rotate([0, 180, 0])`.
*   **Output:** The final output should be a single STL that includes the original mesh with the two magnet holes. I don't need to be able to print it in multiple pieces.
*   **Libraries:** I'm not looking for a complex design, so hopefully just the standard OpenSCAD primitives are necessary, but if any other libraries are needed, I'm ok with that as well. I'm open to any standard library, but I have no idea what is needed.

I'd love it if you could create the OpenSCAD files for me, including any necessary imports or setup. It would be fantastic if the magnet hole code used modules to create the holes, making it easier to add more in the future if needed. I'm also aware that Customizer won't work with STL imports, so it does not need to be designed for that.

[Assistant]
Luci_magnet.scad:
```

/*magnet hole options*/

magnet_1_diameter = 10;
magnet_1_height = 2;
magnet_1_x = -2;
magnet_1_y = -4;
magnet_2_diameter = 10;
magnet_2_height = 2;
magnet_2_x = 19;
magnet_2_y = 45;
circle_resolution = 200;

$fn=circle_resolution;

// flip it all over for better printing
rotate ([0,180,0]){
difference (){
// move the imported STL to match center x
    translate ([-153,-129,0])  {
		import(file = "Luci.stl", layer = "plate", convexity = 20);
    }
// move and create the magnet holes
translate ([magnet_1_x,magnet_1_y,-0.1])
#cylinder (r=magnet_1_diameter/2, h=magnet_1_height+0.1);
translate ([magnet_2_x,magnet_2_y,-0.1])
#cylinder (r=magnet_2_diameter/2, h=magnet_1_height+0.1);
}

Okay, so I'm looking to design a box with a sleeve, and I'd like to be able to control all the dimensions with parameters in OpenSCAD. I want to be able to generate just the box, just the sleeve, or both. The box should have a floor, rounded inside horizontal and vertical corners and chamfered edges where the sleeve slides in. I also want pins on the sides of the box for the sleeve to lock onto. I'm envisioning a hexagonal pattern on the sleeve too, which I'd like to toggle on or off.

Here are the specific parameters I want to control:

*   **Selector:** A dropdown to choose between "Both", "Sleeve", or "Box" to only render a specific piece.
*   **Hex\_On:** A dropdown to turn the hexagonal pattern on or off.
*   **Width:** Overall width of the box.
*   **Depth:** Overall depth of the box.
*   **Height:** Overall height of the box.
*   **Sleeve\_Wall:** Thickness of the sleeve walls.
*   **Sleeve\_Gap:** Gap between the sleeve and the box.
*   **Box\_Wall:** Thickness of the box walls.
*   **Floor:** Thickness of the box floor.
*   **Scoop\_Radius:** Radius of the horizontal inside corner scoops.
*   **V\_Radius:** Radius of the vertical inside corners.
*   **Chamfer:** Size of the chamfers on the box sliding edges.
*   **P\_Dia:** Diameter of the pins.
*   **P\_Inset:** Inset of the pins from the box's edge.
*   **P\_Offset:** Offset of the pin's retention bump.
*   **Hex\_Size:** Flat side measurement of the hexagons in the pattern.
*   **Border:** Minimum distance from the edge to the hex pattern.

I need the design to include:
*   The box with the specified wall and floor thicknesses, rounded corners (both horizontal and vertical), and edge chamfers.
*   Pins on the box sides that create a retention mechanism on the sleeve.
*   A sleeve with the specified wall thickness and a gap from the box. This sleeve should slide over the box.
*   An optional hexagonal pattern on the outside of the sleeve, positioned with the specified border.

Could you generate the necessary OpenSCAD files to achieve this? Also, I am not using any external libraries like MCAD, BOSL, etc. so everything should be self-contained.

Hi, I'm looking to create a parametric machine foot, and I have some specific requirements. I've seen something similar that I quite like, and I'm hoping you can help me create something similar that I can then further modify as needed.

Essentially, I need a foot that's circular on top and bottom, with a hollow cylindrical core for a screw. I need to specify the overall diameter of the foot, its height, the diameter of the screw, the diameter of the washer (or screw head), and the thickness of the bottom of the foot (between the washer/screwhead and the mounting surface). I also want to specify the thickness of the outer wall, relative to the overall foot diameter. Finally, a way to toggle between rounded and non-rounded edges at the top of the foot would be great.

I don't need anything complex with libraries. I'm just trying to get a good starting point for a parametric design in OpenSCAD.

To summarize, the main things I need are:

*   **Parametric control** of the foot diameter, height, screw diameter, washer diameter, bottom thickness, wall thickness ratio, and rounded edges.
*   **Circular profile** for the top and bottom surfaces.
*   **Hollow cylindrical core** for the screw.
*   **Option for rounded or non-rounded** top edges.

Could you help me generate this as an OpenSCAD file? Thanks so much!

I'm looking to create a parametric tap wrench in OpenSCAD. I've seen a design that I like, and I'd like to have something similar, but with a few more options that are easy to customize.

Here's what I'm thinking:

**Core Structure:**
The wrench needs a central square hole to hold a tap. The size of this square, and the depth of the hole, should be adjustable. There should also be small circular holes at each corner of the square to allow for some flex. There should also be a handle that extends from the main body of the wrench.

**Parameters I'd like to control:**
*   **Tap Square Size:** The side length of the square hole for the tap, in mm.
*   **Tap Height:** The depth of the square hole, in mm.
*  **Flex Hole Diameter:** The diameter of the small holes at the corners of the square, in mm.
*  **Grip Length:**  The length of the handle, in mm.
*   **Grip Width:** The width of the handle, in mm.
*   **Grip Height:** The height (thickness) of the handle, in mm.
*   **Material Thickness:** The thickness of the material around the flex holes in mm - this can probably control the whole thickness of the core structure.
*   **Roundness:** A general rounding parameter for the edges of the main body and handle, in mm. I'd like to be able to set this to 0 if I don't want rounded edges.
*   **Debug Mode:** A boolean to toggle rounded edges on or off, for faster rendering.
*   **Resolution:** To control $fn for smooth curves.

**Specifics:**
The central part of the tap wrench, which has the square hole, should be cylindrical, and the handle should extend from the edge of that cylinder. The square hole should go all the way through the cylinder, and should have the corner holes. The handle should be attached to the side of the cylinder, and not protrude into the hole area at all.

I would like the design to be completely parametric, so that I can change all of the parameters above and have the model update accordingly.

I'd also like the ability to use `rcube` for the handle, which I can include in the SCAD file. It will be really helpful for rounding the edges as I need. I'm not sure what other libraries might be helpful, so if there's something you would recommend or include, feel free.

Could you generate the necessary OpenSCAD files for this design?

Okay, I'm looking to create a parametric phone mount for FTC robots, and I want to be able to customize it for different phone sizes and mounting systems. I've seen some designs that use clips to hold the phone, and I like that approach, but I want to be able to control various aspects of the design.

Specifically, I'd like a design that allows me to specify the phone's width and thickness as parameters. I also need to set the overall thickness of the mount itself. I'd like the mount to have a base with mounting holes for Actobotics, goBILDA, and Tetrix. It should use a "center hole pattern" for mounting, with options to extend the mounting holes for each system: that is, in addition to the core hole pattern, there should be options to add more mounting holes in a standard pattern. I want to be able to choose which mounting systems I'm using, so each one should have a boolean parameter to enable or disable it.

Additionally, I want to be able to add gaps along the edges of the mount so that buttons or ports on the sides of the phone aren't covered up. These gaps should be configurable with boolean parameters for the top-right, top-left, bottom-right, and bottom-left corners.

I've seen some designs with straight edges on the clips, and some with curved edges on the clips. I'd like both designs to be parametric and selectable using a single boolean switch, or some other simple means of selecting which clip design is used.

I don't need anything fancy, just a functional, robust, and easily configurable design that works for a wide variety of phones, and the flexibility to select from a variety of mounting hole patterns. I'm not looking for multi-part assemblies: the design needs to be a single part suitable for 3D printing.

I'm expecting the OpenSCAD code will use functions to create each clip, base, and mounting hole pattern, and those will be called in a "master" module. I'm hoping that the overall structure is similar to the example code that I attached (which uses boolean values to enable parts of the design), but it needs to be entirely new code. I'm expecting to use the standard OpenSCAD functions rather than any specialized libraries for the core structure, but I don't know if any libraries for the mounting holes exist. If a suitable library exists, please use it, but if you decide to use a library, please tell me which one you're using. If a library doesn't exist for these mounting hole patterns, you can just make them manually.

I'd like to make a customizable "Springo" based on the Make Anything design. You know, the thing that turns any 3D model into a springy, slinky-like object. I want a parametric OpenSCAD design where I can input an STL file, and then adjust how the springo is created around it. I'm envisioning something like what's already implemented, but I want a new implementation, not a modification of the existing code, and more easily adjustable.

Here are the parameters I need:

*   **STL File Input:** The path to the STL file that I want to "springo-fy".
*   **Positioning:**  X, Y, and Z position offsets for the STL object.
*   **Scaling:**  An overall enlargement and shrinkage factor for the STL.
*  **Turn Direction:** A simple boolean or integer for clockwise or counter-clockwise springo direction.
*   **Springo Width:** The width of the springo portion, expressed as a percentage of the object's radius.
*   **Springo Thickness:**  The thickness of each coil of the springo.
*   **Springo Clearance:** The gap between the coils.
*   **Springo Height:** A separate control for the bottom and top heights of the springo along the Z axis, to truncate the springo if necessary.
*   **Springo Smoothness:**  A setting to control the smoothness of the springo coils, probably using the `$fn` parameter in OpenSCAD for circular segments.

The output should be a single 3D printable object, where the original STL is hollowed out and replaced by the springo coils. I do _not_ need any dependencies or libraries. The file should be standalone, vanilla OpenSCAD. I'm hoping for a clean, well-commented design that will be easy to modify if necessary. Can you generate that for me?

I'd like to design a customizable box organizer using OpenSCAD. I've seen a few designs that are close, but I'd like a more general solution that works a bit differently. I want to be able to specify the outer dimensions, wall thickness, and whether there's a base. But more importantly, I want the internal dividers to be controlled by a grid where I can specify if each unit has a right-hand wall, a bottom wall, or both.

I need a way to define a grid configuration. I think it should be an array or list of arrays, where each inner array represents a row, and each item in that inner array describes the walls for a specific unit. I was thinking of using constants, like `N` for no walls, `R` for right wall, `B` for bottom wall, and `RB` for both. It needs to handle cases where a wall is defined for the very last unit in a row/column, even though the exterior walls act as a wall there.

Here are the specific requirements:

1.  **Basic Dimensions:**
    *   `width`: Outer width of the box.
    *   `length`: Outer length of the box.
    *   `height`: Outer height of the box.
    *   `walls`: Wall thickness (this should be the same for all walls, including internal dividers and the base).
    *   `base`: A boolean to enable/disable the base of the box.

2.  **Grid Definition:**
    *   Constants (`N`, `R`, `B`, `RB` - or something similar) to define wall presence.
    *   A 2D array (`grid`) defining the internal layout. Each element should use the constants. The order of the rows in the array should correspond to the order of the compartments in the organizer from top to bottom, though the math should be able to handle this backwards or forward.

3.  **Calculations:**
    *   Automatically calculate the size of each unit within the grid.
    *   Handle wall thicknesses correctly when calculating the internal dimensions.

4.  **Output:**
    *   Render the box with the outer walls, base (if specified), and internal dividers based on the grid.
    *   Use `cube()` to generate the basic box elements, not other primitives.
    *   I would like the code to make use of a `reverse()` function from a library like dotSCAD, and a `bitwise_and` function from a similar library like that one.

It should be fully parametric, so I can change the grid, dimensions, and wall thickness easily. The code should handle any grid size (as long as all rows have same amount of columns), no hard-coded limits. If you need to use any other specific libraries, please specify them too.

Please provide the complete OpenSCAD file(s) for this design, including the reverse and bitwise functions.

Hey, I'm looking for an OpenSCAD design for a Bahtinov mask. I've seen a few around, but I need something parametric so I can customize it for different telescopes.

Here's what I'm thinking:

*   **Basic Shape:** It needs to be a circular disc with a customizable outer diameter. I need to be able to specify the diameter of the whole mask.
*   **Aperture:**  There needs to be a circular opening in the center for the telescope's aperture. I'll need to specify this diameter, and the design should cut away everything inside this circle, except for the Bahtinov pattern of course.
*   **Center Hole (Optional):** Some telescopes have a secondary mirror in the center. I'd need a customizable circular center hole for that. If I don't have one, it should be set to 0, and not included in the model.
*   **Bahtinov Pattern:** The actual mask part should have the typical three sets of angled bars. I should be able to specify the width of both the bars and the gaps between them. The bar pattern should roughly cover the aperture area and then be clipped to the aperture's boundary.
*   **Structural Support:**  I want some structural bars added to the design, running horizontally and vertically. They should be the same width as the gaps in the Bahtinov pattern.
*   **Outer Margin:** There should be a margin between the edges of the aperture circle and the outer edges of the mask. The width of this margin can be fixed, maybe around 1mm.
*   **Handle:** I would like a small cylindrical handle on the outer edge of the mask. It should extend from the mask to help with installation and removal from the scope.
*   **2D then 3D:** The design should be made in 2D and then extrude to a specified height.

I think that about covers it! I'd like all the parameters to be easily customizable at the top of the file. Please use the default `$fn` of 72 for all circles. No external libraries are needed for this design.

I'd like to make some endcaps for miniature figure trays, similar to the ones I saw on Thingiverse. I've attached a basic OpenSCAD file (endcaps.scad) that generates a simple endcap, but I need something more flexible and customizable.

Essentially, I need a design that creates a rectangular block with a slightly smaller rectangular cutout in the middle, creating a lip around the edge. The height is always the same. The base idea is in the attached file.

I need to be able to control the width, depth, and height of the endcap. I'd also want to be able to control the thickness of the lip.

I'd like to have it parameterized, specifically I need to be able to specify:

*   `endcap_width`: The overall width of the endcap.
*   `endcap_depth`: The overall depth of the endcap.
*   `endcap_height`: The overall height of the endcap.
*  `lip_thickness`: The thickness of the edge lip.

I want the inner rectangle to have a width that is the same as the overall width minus `2 * lip_thickness`, and a depth that is equal to the overall depth minus `2 * lip_thickness`.

Could you generate an OpenSCAD file (or files, if it makes more sense) that does this? I don't need any fancy features, just the basic endcap as described, but it needs to be fully customizable based on the parameters I mentioned. Also, I don't need any external library dependencies.

endcaps.scad:
```
width = 56.31;
depth = 7.05;
height = 7;

//single: w=28.31
//double: w=56.31
//triple: w=84.31

difference () {
    cube([width+2,depth+2,height]);
    translate([1,1,1]) cube([width,depth,height]);
};
```
