Okay, I'm looking to create a lenticular Christmas decoration, and I'd like it to be parametric in OpenSCAD. I have a rough idea of the design, but I need help putting it all together in a way that's easy to customize.

Essentially, I want a flat, elongated base with a series of vertical fins or vanes, kind of like a comb. Each vane will have text on it, viewed from different angles. So, looking at it from one side, you see one set of text; flip it over or look at it from the opposite angle, and you see a different set of text. I imagine the text is slightly raised. I'm planning on using a dual extruder setup, and the idea is for the two sets of text to be in different colors. The main body will be a base color. I'd like it to have a sort of Christmas tree shape extending up from the base as well.

Here are the parameters I'm thinking about:

*   **Overall Dimensions:**
    *   `length`: The overall length of the base. I'd like this to be around 140mm by default.
    *   `width`: The overall width of the base, maybe around 44mm.
    *   `thickness`: The total thickness of the base and fins, starting around 6mm.
    *   `textDepth`:  The height of the raised text, maybe something like .8mm.
*   **Vane/Fin Parameters:**
    *   `numberOfVanes`:  The number of vertical fins/vanes, maybe start with 7.
*   **Text Parameters:**
     *   `text1`: The first word (e.g., "PEACE").
    *  `text2`: The second word (e.g., "STAR").
    *   `text3`: The third word (e.g., "XMAS").
    *   `text4`: The fourth word (e.g., "NOEL").
    *  The text should use a bold Arial style font
*   **Tree Parameters**
    * `branchHeight`: The vertical height between tree branches.
    * `branchStartWidth`: The horizontal width of the first branch
*   **Hole:**
     * `holeDia`: The diameter of a hole to be placed in the base (for hanging the ornament).
*   **Text and Fin Alignment:**
    * I'd like the text to be centered on the fins, and the two different words should be on opposite sides of the fins such that each word is visible from a different angle.

For the Christmas tree, it should grow out of one side of the base in a series of layered branches.  The branches should get wider near the base and narrower at the top.

I think it would be useful if the OpenSCAD file(s) included modules for the base, the fins, the text, and the tree separately to make it easier to modify. Also, the text needs to be properly oriented for dual extrusion so the color change lines up with the visible text. This might mean rotating the text or the extrusion path, not sure. The lenticular effect needs to be carefully controlled. The text needs to be sliced with the fins.

It would also be good if the fins had a slight angle to create a sharper lenticular effect. If you're familiar with the concept, it's similar to how lenticular postcards work. Also, I'd need a way to specify the font to use (Arial bold is fine), direction of text, and spacing. It would be best if this was all done natively without relying on libraries like MCAD or BOSL.

I realize this is a fairly complex design, so if you need to break it down into multiple files or if you have any questions, just let me know. I'd like to be able to adjust these parameters and see how the design changes.

I'd like to create a customizable origami crane design using OpenSCAD. I need it to be parametric so I can easily adjust the size and thickness of the lines.

Specifically, I'd like to control the following:

*   **Maximum Size:**  I want to specify the maximum dimension of the crane (either width or height). The other dimension should scale proportionally.
*   **Model Height:** This will be the thickness of the extruded 2D shape.
*   **Outline Thickness:** The thickness of the outer border of the crane.
*   **Inline Thickness:** The thickness of the lines within the crane.
*   **Inline Edge Radius:** A small radius for the corners of the inner lines.
*   **Flip Model:** A boolean option to mirror the model along the y-axis.

The crane design itself is based on a set of coordinates, both for the outer edges and inner cut lines, which I have. I will provide these coordinates in the form of point lists representing the outline of the crane and cut line polygons. You need to calculate all sizes based off of these points and scale accordingly to the `max_size` parameter. I don't want to have to figure out scaling factors myself.

Also, I don't want any comments in the code that indicate they were generated by AI.

I'd like the output to be a single `.scad` file. I'm not using any additional libraries so none need to be included.

Could you generate the OpenSCAD code for me?

I need help creating an OpenSCAD model for a probe holder that I can use on my CNC. I'm using a Makita compact router, but I want the design to be easily adjustable for other spindles. I'm going to be using limit switches like the ones from this Amazon link: [https://www.amazon.com/gp/product/B00MFRMFS6/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1](https://www.amazon.com/gp/product/B00MFRMFS6/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1).

The basic idea is that it's a block that fits around the spindle and has a hole for the endmill to pass through. There should be mounting holes for the limit switches on the sides, and the design should have some kind of inset area on the mounting faces for the limit switches so they sit flush with the surface. I’ve been using the attached design but I’d like something more flexible and easier to adjust parametrically.

Here are the specific things I need to be able to control with parameters:

*   **Overall height:** How tall the main block is.
*   **Spindle portion height:** The height of the portion that wraps around the spindle.
*   **Spindle shaft diameter:** The diameter of the spindle.
*   **Colette holder clearance:** How much space to leave around the spindle so it slides in easily.
*   **Hole Spacing:** The distance between the centers of the mounting holes for the limit switches.
*   **Inset Depth:** How deep the inset area for the limit switches is.
*  **Inset Height:** How tall the inset area is, and therefore how tall the mounting face is for the switch to rest upon
*   **Inset Offset From Holes:** The distance the inset area is offset from the mounting hole centers.
*   **Separation:** How far from the main body the mounting holes for the switches should be.
*   **M3 Diameter:** The diameter of the M3 bolts.
*  **M3 Nut Width:** The width of the M3 nuts.
*  **M3 Nut Height:** The height of the M3 nuts.
*   **Wall thickness:** The thickness of the walls of the main block.
*   **Side cutoff:** The distance on each side to remove from the wall where it hits the base
*  **M5 Diameter:** The diameter of the M5 bolt used to clamp to the spindle
*  **M5 Nut Width:** The width of the M5 nut
*  **M5 Nut Height:** The height of the M5 nut
*  **Probe Offset:** The distance from the bottom of the block to the mounting holes for the switches
*  **Sides:** The number of sides on the main cylinder that forms the base. This should be six for a hex shape
* **Lip Height:** The height of the lip to help position the holder around the spindle.
* **Lip Min Diameter:** The minimum diameter of the lip so it fits around the spindle.

I'd like to make sure there's a cutout or similar where the endmill can pass through freely when the spindle's mounted in the holder. I also want to be able to adjust the side cutoff, as this helps reduce the amount of material used and doesn't affect the strength of the mount for the probes. I'd prefer using the BOSL2 library if possible, as I'm already familiar with it and it makes a lot of this easier to do parametrically.

I'd like to create a coin trap, and I want it to be parametric so I can adjust it for different sized coins. I want the trap to have a rounded, box-like shape with three cylindrical holes on the sides and a spherical hole in the center. The cylinder holes should also have beveled edges. I've already got some of the basic dimensions worked out so that part should be easy.

Specifically, I need the following:

1.  A `coin_diameter` parameter which determines the size of the coin that the trap is designed to hold, and which all the other sizes are derived from.
2.  A preview mode parameter, `preview`, which controls the number of facets used to render the model. This should also use fewer facets than render mode. 1 should be for preview mode and 0 should be render mode.
3. The overall shape should be a rounded cube. The corners of the box should be rounded with `corner_radius` equal to `coin_diameter/10`.  The rounded cube should be built using the hull operation on spheres, placed appropriately.
4.  The cylindrical holes should be positioned on the X, Y, and Z axes, and should have a radius of `coin_radius-1.5*corner_radius`. They should go all the way through the box and be long enough so that they extend past the edges of the box by at least 5 mm. The cylindrical holes should use the current value of `$fn`.
5. The beveled edges of the cylinder holes should be spherical sections, whose radius, `cylinder_bevel_radius`, is equal to `cylinder_radius+corner_radius/2`, and should be positioned such that they bevel the entry and exit of all the cylindrical holes.
6.  Finally, there should be a spherical hole in the center of the trap with a radius of `coin_radius+1`. It should also use the current value of `$fn`.

I don't have a specific library in mind, so go with whatever is most appropriate for OpenSCAD.

I'd like to create a customizable origami bat design in OpenSCAD, similar to the one I saw on Thingiverse, but I'd like to be able to adjust more parameters. The basic shape is defined by a set of outer points and inner polygons, and I want to control the overall size, height, and thickness of the outlines.

Specifically, I need to be able to set:

*   **Maximum size:** The longest side of the bat (either width or height) in millimeters. The other dimension should scale proportionally.
*   **Model height:** The thickness of the extruded model in millimeters.
*   **Outer outline thickness:** The width of the outer outline in millimeters.
*   **Inner outline thickness:** The width of the inner outlines in millimeters.
*   **Inner outline edge radius:** The roundness of the edges of the inner outlines.
*   **Flip model:** A boolean option to flip the model horizontally.

The model itself is based on a series of coordinates for the outer edge points (A1-A28) and inner polygons (C1-C24), which are defined in the existing file. I need the code to read those coordinates and use them to generate the 2D outline, then extrude it to create the 3D model. It should handle the scaling correctly, so if the user changes the maximum size, the whole model scales appropriately. The code should also make sure that inner outlines are correctly created based on the cut polygons.

I believe I'll need to use the `polygon`, `offset`, `linear_extrude`, `difference`, `resize`, and `mirror` operations, along with the necessary math operations. I'm not using any additional libraries at the moment. Could you generate the complete OpenSCAD file for this?

I'd like to design some custom Christmas ornaments, and I'm hoping you can help me generate the OpenSCAD code for them. I'm looking for something that mimics the shape of those classic blown-glass ornaments, but I want to have a lot of control over the details and add some interesting features like ripples and dimples. I want to be able to change the overall height and width of the main bulb of the ornament, as well as how tapered or round the bulb is. I also need to specify the dimensions for the cap where the hook or loop would go, since I've already got some in mind.

Ideally, the ornaments would have a smooth transition from the cap to the main bulb. The code needs to let me control the transition height and the easing of the transition from cylinder to the more complex shape. For the main shape, I'm looking for a way to add ripples around the surface. I'd like to be able to set the number of ripples, how deep they go (as a percentage of the width), and how much they twist as they go up the ornament. I'm also interested in adding some dimples - I need control over how many there are, how big they are, how far from the shape they sit, and if they should be rotated around the ornament. It'd be nice to preview the dimples as spheres before they're used to subtract from the main shape as well.

I need to specify a quality factor that will impact the layer thickness and the number of radial steps that will be used in creating the shape. I'd also like control over how the ripple strength varies from the cap to the tip, maybe even smooth them out at either or both ends. I'd also like an option to really amplify the ripples, making them into fins. I'd like the option to control how many facets the dimples have (or smooth them out) since I've seen them look a little faceted in some programs. Finally, I need an option to adjust the vertical position at which the shape profile begins, relative to the cap.

I guess I need some way to handle units in both mm, cm, and inches. I'd like to be able to set the shape's height, the shape's width, a shape control parameter to handle the roundness/taper, the cap's diameter, the cap's height, the cap-to-shape transition, the number of ripples, how far the ripples extend in/out, the ripple twist, the number of dimples, the dimple size, the dimple distance from shape, any dimple shifts around the object, and finally a preview option for dimples. I will also need to be able to make some advanced tweaks, like changing the cap shape easing parameter, the shape start parameter, the ripple strength near the cap, the ripple strength near the tip, a ripple fins parameter, the dimple fragments, and the quality factor.

Can you make it so I don't need to rely on an external library? If you could create all of the code directly in one or more .scad files, that would be great. It might be good to also include a few comments for clarity within the code as well.

I need a tea infuser holder designed. It should be a simple, circular cup-like shape that can hold a spherical tea infuser. The holder should have a flat base and slightly raised sides to cradle the ball. I'd like it to be parametric so I can easily adjust the size to fit different tea infusers. The main parameter should be `ballRadius` representing the radius of the spherical tea infuser in millimeters. The holder itself should be slightly larger than the ball to make space for it.

I'm picturing this being created by subtracting a sphere from a cylinder. The cylinder forms the main body, and the subtracted sphere provides the hollow for the ball.

[Assistant]
tea_holder.scad:
```
ballRadius = 40;
$fn=ballRadius*10;
difference() {
    cylinder(h=ballRadius+5,r=ballRadius+5, c=true);

        translate([0,0,ballRadius+5])
            color([0,1,0])
                sphere(r=ballRadius+1);
}

I'm looking for an OpenSCAD design for a stand to hold a curved lithophane, like the ones made by 3DP.rocks. I want to be able to print this in two parts, a top and a bottom, and have a hole to run an LED strip cable through the bottom piece.

Here are the key parameters I need to be able to adjust:

*   **`s`**: The width of the lithophane (along the curve).
*   **`h`**: The depth of the lithophane (the height of the arc).
*   **`walls`**: The thickness of the walls holding the lithophane,
*  **`height`**: The height of the lithophane walls (how far the walls stick up from the bottom and go down from the top),
*   **`thickness`**: The thickness of the bottom part where the lithophane sits, this is usually the max thickness of the lithophane at the bottom.
*   **`bottom`**: Padding for the bottom of the lithophane piece, to create a little space below the lithophane.
*   **`brim`**: The width of the brim around the bottom for better adhesion.
*   **`cableDiameter`**: The diameter of the cable for the LED strip.
*   **`cableOffset`**: The angle in degrees where the cable hole will be placed, with 0 as straight up, 90 as straight right, etc.
*   **`top`**:  The height of the top part walls.
*  **`thicknessTop`**:  The thickness of the top part, where the lithophane sits, this is usually the max thickness of the lithophane at the top.
*   **`spacing`**: The spacing between the top and bottom when both are rendered.
*   **`part`**: a string parameter that chooses which part to render, can be "both", "top", or "bottom".

I want the base of the lithophane stand to be a curved shape that closely matches the curvature of a lithophane made with the outer curve setting from the 3DP.rocks generator, and the top piece will be a similar curve.

It would be really great if the output could generate three separate STLs (or at least allow for this through the "part" parameter): one for the bottom piece only, one for the top piece only, and one for both pieces with a spacing between them.

I don't need any specific libraries, it should all be achievable with base OpenSCAD functions.

I'd like to create a customizable 2D origami cat design in OpenSCAD, similar to the one described in the provided text, but I want to be able to adjust a few more parameters. I need to be able to control:

*   **Overall Size:** Like the original, I need a parameter for the maximum size of the longest side, and the shorter side should scale proportionally.
*   **Height/Thickness:** I want to set the model's thickness.
*   **Outline Thickness:** Control the thickness of both the outer and inner outlines.
*  **Inner Outline Rounding:**  I need a parameter to set the radius of the rounded edges for the inner outlines.
*   **Flip:** A parameter to flip the model along the Y axis.
*   **Base shape:** I want to be able to edit the outer and inner shapes by editing a set of points that describe the outer edge and a set of polygons that describe the inner cuts
*   **Number of polygons:** Instead of having a fixed number of polygons for the inner cuts, I need to be able to edit an arbitrary number of them. Each polygon is described by an array of the outer and inner points.

I want the output to be a single .scad file containing all code and be parametric. Could you generate the OpenSCAD code for this? I want to use the default $fn, or allow it to be specified in the code.

I'd like to create a customizable origami butterfly design in OpenSCAD. I've seen a design I like, and I want to recreate it from scratch with some adjustable parameters.

The butterfly should be 2D, essentially a flat shape that could be laser cut or 3D printed. I need to be able to set the maximum size of the longest dimension of the butterfly, and the shorter dimension should scale proportionally to maintain the shape's aspect ratio. I'll also need to control the overall thickness (or height when 3D printed).

The design has an outer outline and a number of internal outlines that define the wings and body. I need to be able to set the thickness of both the outer and inner outlines. Also, for the inner outlines, I'd like to specify a radius for rounding the ends of these lines.

Finally, I'd also like a simple option to flip the butterfly horizontally, so I can create mirrored versions if needed.

I don't need to use any external libraries for this, everything can be done with basic OpenSCAD commands. The design should use specific coordinates for the outline and inner lines, I'll give you those in the following list, they are based off of a [0,0] origin, note that the units are in the same measurement as max size above. They will be scaled accordingly.

Here are the coordinates for the outer points (the outline), defined as A1 through A22:

A1 = [393, 40];
A2 = [922, 382];
A3 = [1011, 407];
A4 = [1108, 383];
A5 = [1632, 40];
A6 = [1915, 211];
A7 = [1725, 648];
A8 = [1618, 690];
A9 = [1688, 897];
A10 = [1564, 1116];
A11 = [1270, 1216];
A12 = [1115, 827];
A13 = [1079, 873];
A14 = [1014, 954];
A15 = [947, 871];
A16 = [915, 830];
A17 = [760, 1216];
A18 = [467, 1119];
A19 = [339, 892];
A20 = [410, 690];
A21 = [301, 647];
A22 = [112, 207];

These inner points will help define the inner sections, they are named B1 to B4:

B1 = [1014, 447];
B2 = [1016, 477];
B3 = [1545, 720];
B4 = [482, 718];

And the polygons that will define the inner cuts, named C1 to C13:

C1 = [A22, A1, A2, B1];
C2 = [A2, A3, A4, B1];
C3 = [A4, A5, A6, B1];
C4 = [A6, A7, A8, B3, B2, B1];
C5 = [B1, A22, A21, A20, B4, B2];
C6 = [A20, A19, A18, B2, B4];
C7 = [B2, B3, A8, A9, A10];
C8 = [B2, A10, A11, A12];
C9 = [B2, A18, A17, A16];
C10 = [A16, B2, A15];
C11 = [B2, A14, A15];
C12 = [B2, A14, A13];
C13 = [A13, A12, B2];

Let me know if you need anything else!

I'd like to create a customizable Christmas tree using OpenSCAD. I've seen a design on Thingiverse (thing:2694509) that has the features I'm looking for, but I'd like to have a fresh implementation of it. I want to be able to specify:

*   The overall height of the tree, in millimeters.
*   The diameter of the tree at its base, in millimeters.
*   The number of horizontal segments that make up the tree.
*   The number of sides the tree has (which affects its cross-sectional shape, from a low-poly look to a round one).

The tree is essentially a stack of truncated cones (or cylinders if you use a low number of sides) that get progressively smaller towards the top. I need to be able to control each of the above parameters to easily tweak the final design. The original Thingiverse design uses a for loop to generate the stacked segments; I'd like the AI to do the same. I don't need anything too fancy, just a functional tree design. Please provide the complete OpenSCAD code. I am not using any external libraries.

Hey, I'm looking to get a custom suspension mount designed for my RC car. I've already got something that mostly works, but it's not parametric, and I'd like to be able to adjust it more easily.

Basically, it's a mount with two pin holes for the suspension arms. The key parameters are the distance between those pin holes and the height of the mount above the chassis.

Here’s what I'm thinking:

*   **Pin Distance:** This needs to be adjustable. It's the center-to-center distance between the two pin holes that the suspension arms attach to. I want to be able to control the toe-in of my car by changing this distance. I've been using 42mm for zero toe, and that's a good starting point.
*   **Shim/Height:** I need to be able to specify the additional height of the mount. This would be like adding a shim underneath. I want to be able to easily change the height of the suspension mount. I think I need to be able to give positive and negative values for the height. I don't want the mount to break though; be careful with negative values and keep the pin holes structurally sound.
*   **Pin Holes:** The pin holes need to be 6mm in diameter and accept a pin with a diameter of 3mm. They should be reinforced with a sleeve in some way.

My existing design uses some pretty simple shapes, mostly cubes and cylinders, and I’m happy to keep it that way.

I also had a separate text idea, but it might be better to address that in another project. For now, I’d like to keep it simple with just the parametric mount.

It’d be great if you could generate the OpenSCAD file for this. I'd like to be able to change those two core parameters (pin distance, height) and have it generate a new mount. I don't need any external libraries. I don't think it is a difficult part, but I'm not a OpenSCAD expert.

Thanks!

Hey, I'm looking to create a customizable origami owl design using OpenSCAD. I have a basic design already outlined, but need to make it parametric. I want the ability to control the overall size, the height/thickness, and the thickness of both the outer and inner lines.

Specifically, the design will be based on a series of coordinate points that form an outer polygon and several inner polygons that will be cut out.  Here's what I need the OpenSCAD file to do:

1.  **Overall Size:**  I need a parameter called `max_size_in_millimeter` which will define the maximum dimension of the owl. The design should scale proportionally so the aspect ratio is maintained. This parameter should be adjustable.
2.  **Height:**  A `model_height_in_millimeter` parameter should control the thickness of the model (for 3D printing).
3.  **Outline Thickness:**  There should be a parameter `outline_size_in_millimeter` that controls the thickness of the outer shape.
4.  **Inner Outline Thickness:** There should be another parameter `inline_size_in_millimeter` that controls the thickness of inner lines.
5.  **Inner Line Rounding:** A `inline_edge_radius_in_millimeter` parameter should control the roundness of the inner line ends.
6.  **Flipping:**  There should be an option using `flip_model = "yes" / "no"` to flip the whole design along the Y axis.
7.  **Coordinate Points:** Use these specific sets of points to generate the outer and inner polygons. I'll provide those below.
8.  **Polygon Generation:** The code should create an outer shape and then cut out the inner polygon shapes.
9.  **Units:** All the sizes are in millimeters
10. **$fn:**  Set `$fn=32` for smoother curves.

Here are the coordinate points to use for the polygons:

**Outer Points:**
```
A1 = [1609, 769];
A2 = [1994, 914];
A3 = [2231, 865];
A4 = [2335, 706];

**Inner Points:**
```

B4 = [2567, 1524];

B27 = [1687, 2975];
B28 = [2268, 3552];
B29 = [2693, 1601];
```

**Polygons (use these sets of points):**
```
C1 = [A1, A2, B1, A22];
C2 = [A2, A3, A5, B1];
C3 = [A3, B1, A5];

C9 = [B2, B9, B4];
C10 = [B2, B8, B1];
C11 = [A22, B1, B8, B9, B16, B17, B23, B26, B25, B24, B15, B14, B11, B12, A21];

C20 = [A13, A14, A15];
C21 = [B20, B4, B5, B29];
C22 = [B4, B3, B6, A7, A8, A9, B29, B5];
C23 = [B3, B7, A6, A7, B6];
```
`cut_polygons = [C1, C2, C3, C4, C5, C6, C7, C8, C9, C10, C11, C12, C13, C14, C15, C16, C17, C18, C19, C20, C21, C22, C23];`

Can you create the OpenSCAD file for me with all of these features and parameters included? Thanks!

Hi there, I'm looking to design a customizable monitor shelf using OpenSCAD, and I'd like it to be parametric so I can adjust it for different monitors. I've seen a few designs, but I'd like to build one from scratch with a few specific features.

The basic idea is a shelf that sits on the top edge of a monitor, with a front lip and a back support that grips the monitor. I'd need the following parameters to be adjustable:

*   **`monitor_thickness`**: The thickness of the monitor at the top edge.
*   **`shelf_depth`**: How deep the shelf extends forward.
*   **`shelf_thickness`**: The thickness of the shelf itself. This can be different from the overall thickness of the supports.
*   **`front_length`**: The length of the front support that rests against the front of the monitor.
*   **`back_length`**: The length of the back support that rests against the back of the monitor.
*    **`move_mount_distance`**: A parameter to move the vertical support of the mount horizontally, for very thin monitors.
*   **`monitor_back_slope`**: An angle for the back support, to match a sloped back of a monitor.
*    **`monitor_top_wedge`**: An angle for the top of the monitor, to match a monitor that slopes downward away from the screen (not just the back)
*   **`shelf_width`**: The overall width of the shelf.
*   **`shelf_lip_size`**: The size of a lip on the front of the shelf to keep items from falling off.
*   **`bead`**: Radius of a bead along the joints. (should probably be derived from `shelf_lip_size` and a `thickness` parameter).
*   **`thickness`**: General thickness of the plastic of the supports
*   **`test_profile`**: Boolean to generate just a thin test profile of the mount.
*    **`lego_top`**: Boolean to include a LEGO compatible surface on top of the shelf

I'd also like to incorporate LEGO compatibility on the top surface as an option (I've seen the calculations for this in another project). So, I'll need the following LEGO parameters as well:

*   **`h_pitch`**: Horizontal unit for LEGO studs.
*   **`v_pitch`**: Vertical unit for LEGO studs.
*   **`tol`**: Tolerance for LEGO fit.
*   **`k_dia`**: Diameter of a LEGO knob.
*   **`k_height`**: Height of a LEGO knob.
*    **`k_n`**: Resolution for the knob.
*   **`wall`**: Wall thickness for LEGO brick.
*   **`brick_cyl_ex`**: Outer diameter of the LEGO brick cylinder.
*   **`brick_cyl_in`**: Inner diameter of the LEGO brick cylinder.
*   **`beam_cyl`**: Diameter of beam support.

I think that's everything. Could you generate the necessary OpenSCAD code for this? I do not want to use any external libraries.

I'd like to create a customizable 2D T-Rex design, similar to the Chrome offline game's dinosaur, that I can then 3D print. I'm thinking of something that could be used as a decoration, maybe in a picture frame or even as a pendant.

The design should have these features:

*   **Overall Shape:** It needs to match the general outline of the T-Rex as shown in the provided SCAD file, including the legs, body, head, and tail shape. There are some "cutout" polygons in the design that should be included.
*   **Size:** I need to be able to control the maximum size of the longest side of the design, and the other side should scale proportionally to maintain the correct aspect ratio.  I'd like to specify this size in millimeters.
*   **Height/Thickness:** I need to control the height of the model, also in millimeters. This will be the thickness of the 3D printed part.
*   **Outlines:** I need to have both an outer and inner outline, and I need to be able to control their thicknesses independently in millimeters.
*   **Inner Outline Edges:** I'd like to be able to control the roundness (radius) of the inner outline edges, in millimeters.
*   **Flipping:** I should be able to optionally flip the model horizontally (mirror it across the Y-axis) if necessary.
*   **OpenSCAD:** This all should be done parametrically using OpenSCAD so I can customize these settings.

I don't need any particular external libraries. I'm hoping you can generate the necessary OpenSCAD code.
