Okay, I'm looking to design a personalized pen body using OpenSCAD, and I have some specific requirements. I'd like the design to be parametric so I can easily adjust it for different pens or to customize it further.

Here's what I need:

**Core Functionality:**

*   **Pen Body:** The primary function is to create a pen body that houses a standard Pilot G2 ink cartridge. The design should include a hollow core to fit the cartridge, and an outer shell to form the body of the pen.
*   **Cap:**  The design must also include a cap that fits snugly onto either end of the pen body. The fit should be tight enough to stay on, but not so tight that it's impossible to remove.
*   **Plug:** There should be a plug for the end of the pen to secure the ink cartridge. It should insert and have a locking mechanism (e.g., a twist lock) to prevent it from easily falling out.
*   **Personalized Text:** I need to be able to emboss or engrave personalized text onto the pen body. This text should be customizable, including the text content, font, spacing, height and position on the pen body. The ability to do left or right handed text is important, so the direction of the text should be controllable as well.

**Specific Dimensions & Parameters:**

*   **Cartridge Fit (Pilot G2):**
    *   Inner diameter (ID) of the pen body to fit the Pilot G2 cartridge. The existing code has it at 7mm, but it would be good if this could be a parameter.
    *   Overall cartridge height, and how far back into the pen body the cartridge can go (including accounting for the plug) should also be parameterized, as the total pen height is dependent on this value.
    *   Tip diameter where the pen body meets the cartridge tip should also be a parameter.
*   **Pen Body:**
    *   Outer diameter (OD) of the pen body.
    *   Overall height/length of the pen body.
    *   Number of sides for the pen body (e.g., round, hexagonal).
*   **Cap:**
    *   Outer diameter (OD) of the cap.
    *   Inner diameter (ID) of the cap, to fit snugly over the pen body.
    *   Overall height of the cap.
    *    Clearance between the cap ID and pen body OD.
*   **Plug:**
    *   Diameter of the plug to fit into the pen body.
    *    Height of the plug.
    *   Details of the locking mechanism.
*   **Text Parameters:**
    *   Text string.
    *   Font selection (including basic, futuristic, and fancy options, as in the example). The code example specifies the font file as a dxf file.
    *   Text height/scale.
    *   Letter spacing.
    *   Vertical position of the text on the pen body.
	*   Text rotation to specify right or left handed text.
*   **General:**
    *   Clearance between parts for printing (e.g., cap and pen body).
    *   Option to include support structures under the tip of the pen (to reduce warping).
    *   Option to include 'ears' on the ends of the pen to further reduce warping.

**Modules:**

The provided code defines several modules ( `body`, `tip1core`, `tip2core`, `core`, `plugCore`, `writeText`, `writing`, `pen`, `printable`, `capcore`, `cap`, `plug`, `print_cap`, `print_body`, `print_plug`, `print_support` ) . I would like the generated code to also be modular using a similar or better organization.

**Libraries:**

The provided code uses `write/Write.scad` for text and `utils/build_plate.scad` for the build plate, I would want the response to include these, or similar libraries if appropriate.

**Additional Notes:**

*   The design should be easily customizable through parameters.
*   I would like the generated scad file to be well-organized and commented, to help me understand and modify the design further.
* The included code handles single and dual extrusion, and it would be great if that behavior was preserved.

Could you please generate a parametric OpenSCAD file based on these requirements?

Okay, I'm looking to create a parametric, printable fastener similar to Velcro, but using interlocking mushroom-shaped posts instead of hooks and loops. I've been experimenting, and I'm mostly happy with the basic design, but I'm hoping an AI assistant can help make it more robust and flexible.

I've attached my current OpenSCAD file ("Fastener_v1_0.scad") as a starting point. It defines the basic geometry: a rectangular platform with an array of mushroom-shaped posts on top.

Here are my key requirements for the new design:

1.  **Parametric Control:** I need to be able to adjust all the key dimensions of the fastener, including:
    *   **Overall Width and Length:**  Like my current `Width` and `Length` parameters, but I also want the option to adjust the size of the platform.
    *   **Post Spacing:** The horizontal and vertical spacing between the posts should be individually adjustable parameters, rather than just relying on the `NotchDistance` which doesn't clearly indicate what we're spacing.
    *   **Post Dimensions:**
        *   **Notch Diameter:**  This is the diameter of the wide part of the mushroom. This is currently calculated as `NotchSize/100` and I would like a variable for `NotchDiameter`.
        *   **Stem Diameter:** I'd like a separate parameter controlling the stem diameter. This is currently calculated in two parts of the code, once as `NotchShape*NotchDiameter/2` and then as `NotchDiameter/2` again. I would like a single `StemDiameter` parameter.
        *  **Mushroom Height:** The overall height of the post, i.e., how high the 'mushroom' stands off the platform. This is currently the sum of `NotchHeight` (1.3) and `NotchHeight * 0.3`. I would like a single `MushroomHeight` variable.
        * **Stem Height:** How tall is the stem itself from the base. This is currently indicated by `NotchHeight`.
        *   **Post Shape:** Currently, the 'mushroom' shape is a frustum (truncated cone). I'd like an option to choose between a frustum and a rounded mushroom shape (e.g., using a sphere or torus). Perhaps an enum `["frustum", "rounded"]`.
    *   **Platform Height:** The height of the base platform. I want to adjust this.

2.  **Interlocking Behaviour:** I want the ability to easily adjust the design of the posts so they interlock securely with another identical fastener. I need the ability to add a small undercut or a slight angle to the mushroom cap to allow for secure interlocking. I'm open to suggestions on the best way to achieve this - maybe some additional parameters or alternative post shapes.

3.  **Array Handling:** I would prefer to use more modern looping methods (e.g. using `for` with vector ranges) instead of the `for` loops and `floor()` in the original design to be more flexible.

4.  **Libraries:** I would like the design to be compatible with BOSL2. I don't need to use every possible feature of the library, but it should be using BOSL2 for some of the functionality.

5.  **Modularity**: The basic unit should be a single post, the platform, and the array of posts should be their own modules, so that I can re-use them as needed.

6.  **Comments:** Please ensure the generated SCAD file is well-commented, explaining the purpose of each section, parameter, and module.

7. **Units**: Please use millimeters for all units.

Essentially, I'd like a more sophisticated, flexible, and parametric version of my existing design, leveraging best practices. Can you provide an improved version, using BOSL2 to implement the changes described?

// Width of your fastener in mm
Width=10;

// Length of your fastener in mm
Length=20;

// Notch Size. This makes determines the holding force. For me 140 was a bit loose and 150 was really tight.
NotchSize=145; // [130:160]

module Fastener(){
NotchDiameter=NotchSize/100;
PlatformHeight=0.7;
NotchDistance=2;
NotchHeight=1.3;
NotchShape=0.9;
$fn=12;

cube([Width,Length,PlatformHeight]);

for(i=[1:NotchDistance:NotchDistance*floor(Width/NotchDistance)]){
for(j=[1:NotchDistance:NotchDistance*floor(Length/NotchDistance)]){
translate([i,j,PlatformHeight]) cylinder(r1=NotchShape*NotchDiameter/2,r2=NotchDiameter/2,h=NotchHeight);

Okay, I'm trying to design a customizable button using OpenSCAD. I've seen some great tutorials that got me started, but I need help making it a bit more robust and user-friendly with parameters.

Basically, I want a cylindrical button with some options for holes and an optional lip and edge. Here's a breakdown of what I'm looking for:

**Overall Shape:**

*   The base of the button should be a cylinder.
*   I need to be able to control the **diameter** and **height** of this cylinder.

**Holes:**

*   I want to be able to choose the **number of holes** in the button – between 1 and 5.
*   All holes will be cylindrical, and I need to be able to control their **diameter**.
*   I also need to be able to adjust their **offset** from the center. For multiple holes, they should be arranged in a pattern.
    *   **1 Hole**: Centered.
    *   **2 Holes**: Symmetrically placed along the x-axis on either side of the center.
    *   **3 Holes**: Placed in a triangle shape centered on the origin.
    *   **4 Holes**: Placed in a square shape centered on the origin.
    *   **5 Holes**: Placed in a pentagon shape centered on the origin.

**Lip and Edge:**

*   I'd like to optionally add a slight lip or raised edge to the top of the button.
*   The **lip** should be a cylinder extending from the top surface of the main cylinder. I need to be able to adjust the lip height as a percentage of the base cylinder height (e.g. 60% of the main cylinder height for the base of the lip). It should extend above the main cylinder by a set constant value, not a proportion.
*   The **edge** should be a cylinder with a slightly larger diameter than the main button. The diameter of this edge should also be controlled as a percentage of the main button diameter (e.g. 90% of the main button diameter). I think it should start from the top of the lip, if a lip is included, otherwise from the top of the button.

**Parameters:**

I need to be able to adjust all of these through parameters:

*   `diameter`:  The diameter of the main button cylinder.
*   `height`: The height of the main button cylinder.
*   `number_of_holes`: The number of holes (1-5).
*   `hole_diameter`: The diameter of the holes.
*   `hole_offset`: The offset of the holes from the center.
*   `lip_ratio`: The height of the lip's base as a percentage of the main cylinder height.
*   `edge_ratio`: The diameter of the edge cylinder as a percentage of the main cylinder diameter.

**Other:**

*   I'm not too concerned about the *depth* of the holes. They can just go right through the button.
*   I'd prefer to have the button centered at the origin.

Could you please generate the OpenSCAD code for me? I'm not using any libraries beyond standard OpenSCAD features.

Okay, I'm trying to design a customizable ziggurat-like structure in OpenSCAD, and I've got a basic concept working, but it's not quite flexible enough for what I need.

Here's what I'm going for: I want a series of truncated cones stacked on top of each other, each with a slightly increasing radius, kind of like a stepped pyramid. I need to control the bottom radius, the top radius of the final cone, the height of each step, and the number of steps (layers). Importantly, each layer should also have a slight height *increase* from the previous layer, starting from the base. I want the increasing height to be a fixed parameter, not a percentage change, for example.

I've tried to implement it using a for loop and `cylinder` but it’s a bit rigid.  Specifically:

1.  **Bottom Radius:**  I need a parameter to set the radius of the very first cylinder at the bottom of the stack.
2.  **Top Radius:** I want to control the radius at the top of the *last* cylinder.  This radius should be used at the top of the final cylinder.
3.  **Number of Layers:** I need a parameter to control the total number of steps in the ziggurat.
4.  **Height:** I need a parameter to set the base height of each layer.
5.  **Height Increase:** I want a parameter to control the *additional* height added to each successive layer.

Ideally, the code would use a module to create the ziggurat. The module should handle the stacking and the incremental height adjustment of the steps. It would be helpful if the module could calculate the radius of each layer automatically based on the bottom radius, the final top radius, and the number of layers using a linear interpolation, so that I only have to specify the two ends. I also need the final z-translation to be calculated automatically so that each cylinder stacks nicely.

I am _not_ looking for a spiral staircase ziggurat.

I would like to avoid relying on any libraries, if possible, so just the basic OpenSCAD primitives and features would be preferred. Please generate the OpenSCAD file for this customizable ziggurat.

Okay, I'd like to design a customizable die, and I'd like to use OpenSCAD. I need a design that lets me control several aspects of the die, and I've got a pretty specific idea of the kinds of options I want.

First, I need to be able to set the overall width of the die, and I’d like to be able to specify that using a variable. Let's start by calling it `die_width`, and it should have a reasonable range to allow for smaller or larger dice, so maybe have that adjustable from 5 to 20.

Next, I want to be able to pick the colors for the main body of the die and the symbols on the faces separately. I'd like to have predefined color options, so let's say "red", "green", "blue", "yellow", and "white" for both the die body and the symbols. So, I'd need two variables: one called `Die_Color` and the other `Symbol_Color`.

I’m also really interested in making sure the die looks smooth and high quality so I’d also like to control the resolution for the curves, and I'll need a variable to set the `$fn` parameter in the code, let’s call that `resolution`. I'd like to be able to set this value between 22 and 36.

I would also want the option to round the corners. It should be a toggle variable called `rounded`. It will be either 0 (false) or 1 (true).

Now for the faces themselves, I'm looking to do a few different things with the markings on each face. For each of the six sides, I want to choose between two modes: either using a series of dots, similar to a standard dice, or using custom characters. So, I'll need 6 variables for each side, let's call them `side_1_mode` through `side_6_mode`, each with the option of 0 (dots) or 1 (characters).

If I choose the "characters" mode for a side, then I’ll need the text itself, the size of that text, the rotation on the face, and the font that is used. So, for example, for the text on side 1, I would have `side_1_characters`, `side_1_size`, `side_1_rotation`, and `side_1_font`. I need all of those variables for all six sides: `side_2_characters`, `side_2_size`, `side_2_rotation`, `side_2_font`, and so on.

For the font, I would like to use the "write/Letters.dxf" font that is included with the Write.scad library, as well as "write/orbitron.dxf" and "write/BlackRose.dxf" as well. I need to include the Write.scad library.

For the dot mode, the size of each dot should be specified by the same `side_*_size` variable that is used to specify the text size in the character mode. I'd also like to control rotation for the dots with the same rotation variable as well, `side_*_rotation`

Finally, I would like to have an option for dual extrusion. If it's turned on, then only the symbols on the faces should be output. I would like to have a variable for this, called `dual_extrusion`, set to 0 for "off" or 1 for "symbols only." This means in dual extrusion mode it should print a thin shell version that has the color of the Symbol color and has only the symbols.

So, in summary, I'd like to control:
*   Overall die width (`die_width`)
*   Die body color (`Die_Color`)
*   Symbol color (`Symbol_Color`)
*   Curve resolution (`resolution`)
*   Rounding of corners (`rounded`)
*   Mode for each face: dots or character (`side_1_mode` through `side_6_mode`)
*   Character text for each side (`side_1_characters` through `side_6_characters`)
*   Character/dot size for each side (`side_1_size` through `side_6_size`)
*   Rotation of characters/dots on each side (`side_1_rotation` through `side_6_rotation`)
*   Font for each side (`side_1_font` through `side_6_font`)
*   Dual extrusion mode (`dual_extrusion`)

Also, the `write/Write.scad` library will need to be included at the beginning. Please make sure that the code is well formatted and commented. Also, please use the `main()` module to call the code.

Okay, I'm looking to create a customizable luggage tag that holds a card, and I'd like it to be parametric so I can adjust the card size. I also want to be able to adjust the amount of material around the card and make some other tweaks.

Here's what I'm envisioning:

The tag should be composed of two parts: a base and a top. The base will hold the card and the top will clamp it down. They will be bolted together at each corner.

**Card Dimensions and Fit:**

*   **Card Width:** I want to be able to set the width of the card that fits into the tag.
*   **Card Length:**  I want to set the length of the card.
*   **Card Height/Thickness:** I need to set the thickness of the card (this is likely a small value, since it's just a card).

**Extra Material/Size:**

*   **Extra Thickness X/Y:** I need a way to set extra material around the card in both the X and Y directions. This helps the card fit within a frame.
*   **Extra Thickness Z:**  I want to control the extra material applied to the base and top separately in the Z direction. This will determine the thickness of each part, so the total thickness of the assembled tag is actually 2 * extraZ + cardThickness.

**Visibility Window:**

*   **Visible Percentage:** I'd like a parameter that controls how much of the card is visible through a window cut in the top piece, expressed as a percentage of the card's dimensions.

**Logo (Optional):**

*   **Logo Cutout:** I'd like an option to toggle a logo cutout in the base. It should use the Open Source Hardware logo.

**Other Details:**

*   **Layer Height:** I need a parameter that determines the layer height used to create a solid bridge, which I think should be disableable.
*  **Bolt Diameter:** I want to specify the diameter of the bolt used to join the two halves of the tag together.
*  **Recessed Bolt Head:** I want to include parameters for a recessed bolt head, specifically the head's diameter and height. If the bolt head should _not_ be recessed, it would be acceptable to simply set the head's diameter equal to the bolt diameter.
*   **Hex Nut Recess:** I need parameters for a recessed hex nut on the base, specifically the diameter of the nut recess and the height of the recess.

Essentially, I'd like the OpenSCAD file to have all these parameters exposed and configurable.

I also think it would be good if the design is flexible enough that the user can easily change the location of the bolt holes. Perhaps they should be a fixed distance away from the edge or from each other. For now, I can live with just the four in each corner, but please include that in the design for the future. Also, I think it'd be good to have a small notch in the top piece that helps to align the two pieces when assembling the tag.

Finally, this all feels like it should just be one OpenSCAD file with a single root `module`.

To clarify, I am *not* expecting you to be able to implement all of this *right now*. For this iteration, you should produce a functional OpenSCAD file that is parametric. You should not use any libraries beyond the core OpenSCAD features; I expect the code to be entirely in a single `.scad` file.

Okay, I'm looking to design a customizable, modular magic wand using OpenSCAD. I really like the spiral/wiggle effect in the example I found and want to make something similar but with a few more options and a focus on printability.

Here's what I'm thinking:

**Core Features:**

1.  **Modular Design:** The wand should be composed of segments that screw together. I need at least three types of segments:
    *   **Top Segment:** This will have a decorative top (a sphere, maybe with some options) and a screw-in socket on the bottom to connect to other segments. It should also have space for an LED and potentially a small battery or wiring for external power, within the top sphere.
    *   **Middle Segment:** These will be the "body" of the wand. They should have a screw on top and a screw-in socket on the bottom.
    *   **Bottom Segment:** This segment will have a screw on top, and a tapered bottom for a nice finish.

2.  **Spiral/Wiggle Effect:**  I want to maintain that cool wavy, spiral effect on the outer surface of each segment, controlled by parameters. Specifically, I want to be able to:
    *   Control the amplitude of the "wiggle" (how much it deviates from the cylinder shape)
    *   Control the number of wiggles per segment.
    *   Choose between a regular spiral and counter-spiral for a "cross shape" pattern.

3.  **Threaded Connections:** The screw connections need to be functional and printable without supports. The provided code uses a clever approach of cone-shaped screw threads that I would like to replicate (or improve, if possible). They also should be parameterized for tolerance.

4.  **Decorative Top:**  The top segment should end in a sphere (or other shape) of configurable size, with an optional thinness for a translucent look. The sphere should also be able to be vertically stretched into an egg-like or oblong shape. I want to be able to add decorative features to the top, but can discuss that more after we get the base design working.

5.  **Customization Parameters:** I want to control a wide range of aspects, so I need many parameters for the following:
    *   Segment height
    *   Wand radius
    *   Wiggle amplitude
    *   Number of wiggles per segment
    *   Spiral direction
    *   Sphere size
    *   Sphere vertical stretch
    *   Sphere thinness
    *   Print resolution (number of facets for curves)
    *   Screw thread clearance
    *   Battery hole dimensions (radius and height for cylindrical space)
    *   LED hole dimensions (radius and height for cylindrical space)
    *   Wire channel dimensions
    *   Optional build plate dimensions (or some way to preview the parts on a build plate)

**Specific Requests and Questions:**

*   Can you make the battery compartment optional? I might want to power the LED externally for smaller builds, and would want to avoid printing an unnecessary internal cavity
*   The example code's screw and nut implementation works well. I would like to use something like that. Is there a standard thread module I should know about before using that approach? Is there a better standard library approach?
*   Can you add a preview mode where we can assemble the wand virtually to see how the whole thing looks before printing? This could be using 'exploded' views for individual parts.

**Libraries:**

I'm not using any specialized libraries right now, but am open to using one. Let me know if one would be helpful.

**Output:**

I want the final output to be a single .scad file with all the parameters at the top and well-commented so I can easily change things.

I think that's about it for now. Let me know what you think, and if you need any further details from me!

//
// Solder one LED lead to center of 15 mm disk (top of AA) so
// that the LED sticks up straight from the center of the disk.
// Solder wire to other LED lead, shrink wrap to avoid shorts.
// Slide LED assembly into rod, so that disk stops at top of
// battery compartment and LED is within the sphere, with wire
// trailing out of rod.

// Solder other end of wire to the spring.

// Insert AAA batteries into rod, so that + end of battery presses
// against disk, and press the spring against the - end.
//
// If the LED does not light, check your connections.
//
// If it worked when contact is made by hand, verify that it works
// when you screw another rod segment into the bottom of the top
// rod segment. The LED should light when the lower rod segment is
// screwed in tightly, and should go out when it is loosened
// or removed. The spring should go around the point of the lower

Okay, I'd like to create a customizable wrench, and I'd like an OpenSCAD file that lets me easily adjust the key parameters. I have a basic design in mind that I'll describe, but I need it to be parametric so I can change the dimensions and the text on the wrench.

The wrench design is essentially a modified dogbone shape, composed of three main parts: two cylinders at either end connected by a rectangular prism. I'll need to specify the nut size this wrench will fit, which will define the diameter of the wrench's jaws.

Specifically, the design should allow for these things to be changed:
*   **Nut Size:** The wrench will be designed to fit a specific nut size. This should directly affect the opening size of the wrench as well as the size of the jaws.
*   **Tool Height:** This is the thickness of the wrench itself.
*   **Tool Length Adjust:** A multiplier to adjust how long the overall length is. It should adjust the length of the rectangular section of the wrench, effectively spacing the jaws further apart
*   **Message:** The text engraved on the wrench.
*   **Font:** Which font to use for the engraving.

Here's the breakdown of how it should work and some of the design specifics I want:

1.  **Basic Shape:**
    *   Two cylinders will form the wrench's jaws, positioned at either end of a central rectangular prism.
    *   The cylinders should have a diameter slightly larger than the specified nut size, with a configurable margin that I will define (kerf). The cylinders should be centered on the length of the wrench.
    *   The rectangular prism connects these cylinders, effectively forming the "handle" of the wrench and the body of the dogbone.
2.  **Wrench Jaw Cutout:**
    *   Each jaw will have a hexagon cut out from it which fits the nut. The hexagon needs to be sized using the nut size defined earlier, and have a margin.
    *   There should be an additional clearance cut, also based on the nut size that is used to clear the base of the nut..
3.  **Engraving:**
    *   The specified text should be engraved onto the body of the wrench.
    *   I should be able to select the font from a list of available .dxf fonts (such as the ones found in the `write/` directory of the MCAD library).
    *   The text should be centered on the rectangular prism section, and the height of the text should be scaled using a multiplier that is dependent on the nut size. The text should not be flush with the surface of the part and should be set below by a reasonable amount.
4.  **Libraries:**
    *   I will need the `shapes.scad` and `Write.scad` files from the `MCAD` library in OpenSCAD to create the basic shapes and do the text engraving. I do not need the files included, just that the code will use them.

So, to summarize, I need a parametric OpenSCAD file that allows me to customize the wrench dimensions, text, and font. The design should include two cylinders connected by a rectangular prism, with hexagonal cutouts to fit the nut, and engraved text on the body. I need to use the `shapes.scad` and `Write.scad` files in the MCAD library for this.

Okay, I need a parametric OpenSCAD design for making round things with angled sides, like lids, dishes, cups, and even frisbees.

Basically, I want to be able to specify:

*   **The internal diameter at the base (bottom):**  This will let me set how big the bottom opening is. Let's call this `base_diameter`.
*   **The internal diameter at the top:** This will let me control the size of the opening at the top, which can be different than the base for angled sides. Let's call this `top_diameter`.
*   **The height of the sides:** This will be the distance between the top of the base and the top edge of the object.  Let's call this `side_height`.
*   **The thickness of the base:** This sets how thick the flat bottom part is. Let's call this `base_thickness`.
*   **The thickness of the wall:** This will be the thickness of the sides.  Let's call this `wall_thickness`.

I'd like to be able to adjust these parameters to create different kinds of objects, like a lid with straight sides, a cup that tapers, a vase, or a flat dish.

The design should use a `linear_extrude` for the base and a `cylinder` for the sides with a difference() to hollow it out, like in the example I saw.

Also, I'd like it if you can include a function to show the build plate for my printer. It's a Type A Machines Series 1, which has a build plate of 230mm x 200mm. I'd like to use the `build_plate` function from `utils/build_plate.scad` so that I don't have to define the build plate size every time I want to see it. Please make sure it shows the build plate by default.

Could you generate the OpenSCAD code for this?

Okay, I'm looking to design a custom, curvy, star-like bowl or vase, but I want it to be parametric so I can easily change the size and shape. I'd like to control the following aspects of the design:

*   **Overall Shape:** I want to be able to define the diameter of the base and the top opening separately, as well as the height of the object. I also want to control the number of "points" or segments around the circumference - fewer for a star, more for a smoother circle.
*   **Grooves:** I'd like to be able to create a groove or sharpness in those points, so I can create sharper star points or smoother curves, with a groove depth percentage.
*   **Curvature:**  The walls shouldn't necessarily be straight, so I want a parameter to control the curvature of the wall. A positive value will make it thicker in the middle, a negative value thinner, and zero will give a straight wall.
*  **Ovality:** There should be a parameter to control how oval the shape is, for a value of 100 it should be circular.
*   **Wall Thickness:** The wall thickness should be adjustable and should have a value in mm.
*   **Bottom Thickness:**  I want to control the thickness of the bottom of the object and make this adjustable as well.
*   **Hole:** I'd like the option of having a circular hole in the bottom, with a defined diameter.
*   **Cross Section Preview:** For debugging purposes it would be cool to have an option to show a cross section of the design.
*   **Build Plate:** For visualization I would like to include standard build plates like the Replicator 2, Replicator, Thingomatic, or also have a manual build plate with user defined dimensions

I think that covers everything. I'd like to get this all implemented in a single OpenSCAD file, and it needs to be entirely parametric, so I can tweak all of those settings. Please let me know if anything is unclear or if I need to specify anything else, and thank you so much for this.

Okay, I'd like a parametric OpenSCAD file for a stamp handle.

The handle should have a tapered, pyramid-like base, and a curved, ergonomic top that incorporates a small sphere. I want to be able to adjust the overall width and length of the base, as well as the height.

Specifically:

**Base:**
*   The base should be a truncated pyramid, with a rectangular base.
*   I want to be able to control `WIDTH` and `LENGTH` of the base rectangle.
*   The overall height of the pyramid should also be adjustable. The pyramid should not be a full pyramid but should be cut off at a certain height.
*   I want to control the height at which the pyramid is truncated (i.e., where the taper stops and becomes a cylinder).

**Top/Handle:**
*   The top should have a curved profile.
*   I want a single extrusion to create a curved handle shape on the center of the top of the base. I would like to control the specific shape of the 2D profile being extruded. The profile should start and end on the X axis.
*   I want to also be able to adjust the Z position of the extrusion.
*   The handle should also have a small sphere on top, slightly inset. I want the sphere radius to be adjustable, and to have control over its X and Z position relative to the top of the curved handle.

**Parameters:**
*   `WIDTH`: Width of the base rectangle.
*   `LENGTH`: Length of the base rectangle.
*   `PYRAMID_HEIGHT`: Total height of the pyramid base.
*   `TRUNCATION_HEIGHT`: Height at which the pyramid is truncated/becomes cylindrical.
*   `PROFILE_POINTS`: An array of points defining the 2D profile of the curved handle.
*   `HANDLE_Z_OFFSET`: Z offset of the curved handle from the top of the truncated pyramid.
*   `SPHERE_RADIUS`: Radius of the sphere on top of the handle.
*   `SPHERE_X_OFFSET`: X offset of the sphere from the center of the handle.
*   `SPHERE_Z_OFFSET`: Z offset of the sphere from the top of the handle extrusion.

I'd like the design to use the standard OpenSCAD library functions for creating the pyramid, extrusion, and sphere. I don't need any external libraries for this design.

Could you provide the OpenSCAD code for this?

	   translate([0,0,5]) cube([WIDTH,LENGTH,200]);
	}

	translate([WIDTH/2,LENGTH/2,5]) {
		rotate_extrude($fn=200) polygon(points=[[0,0],[3.5,0],[4.5,3],[3.5,6],[5.5,25],[0,27]]);

Okay, I need a parametric OpenSCAD file for a stamp handle.

The basic design has a rectangular base, a raised grip area, and a small angled brace connecting the base and grip.

The base should be a rectangular prism, centered on the origin in x and y, with its bottom face at z=0. The base needs parameters for `WIDTH`, `LENGTH` and a thickness of 2.5, with the top of the base at 2.5.

The grip is centered on the origin, like the base, but it's taller (top at z=10+2.5=12.5) and slightly smaller than the base. The grip should also be a rectangular prism, with a length of 6 and parameters for a width offset from the base. The width of the grip should always be a fraction (e.g. 0.3) smaller than the width of the base, e.g. if the base is 60 wide and the offset is 0.3, the grip should be 60-0.3*60 = 42 wide.  The grip needs to be created with a `difference()` using the same logic described below for the brace, with a centered cylinder subtraction at each end, for a radius at least 10 times the `LENGTH` and `WIDTH` to be outside the shape.

The brace is a smaller prism, oriented diagonally. It should attach to the base at the specified point (5.7, -1.25, 3.25) and then angled up at 45 degrees to the grip. It is composed of a `cube`, and a second `cube` which is perpendicular to the first and translates up in y, both created using `rotate()`. This second `cube` should be joined to the angled `cube` at one point along the edge. It should have parameters to control the `BRACE_X`, `BRACE_Y`, and `BRACE_Z` as the location of the center of rotation and the `BRACE_WIDTH` , `BRACE_DEPTH`, and `BRACE_HEIGHT` of the angled portion of the brace and the straight portion of the brace.

Please make all dimensions parametric so I can easily adjust the overall size and proportions of the stamp handle. I'd like to be able to control the base dimensions (`WIDTH` and `LENGTH`), the grip offset factor, and the brace dimensions (`BRACE_X`, `BRACE_Y`, `BRACE_Z`, `BRACE_WIDTH`, `BRACE_DEPTH`, and `BRACE_HEIGHT`). The height of the grip should remain constant, as it's important to fit inside a stamp body.

Use comments to clearly identify each part of the design (base, grip, brace). Also, it would be helpful if the final code uses the `color()` function to use the same green for the grip and red for the brace, like the example file.
