I'd like to design a pepper mill inner saucer that can be customized for different sized mills. I need an OpenSCAD file, or a few files if it makes sense, that will let me specify the outer and inner diameters of the mill, and the saucer will then be created to fit.

The saucer needs to have a base, a wall rising up from the base, and a small connector where the wall meets the base. I'll need to be able to specify the thickness of the base, the thickness of the wall, and the height of the wall. Also, I'd like to specify the size of the edge bevels on the top and bottom of the saucer.

Also, it should have the word "Pepper" embossed on the side of the saucer, repeated twice around the circumference of the wall, and then have small dashes separating the letters to make them more legible after printing, like the file provided. I'd also like to specify which font to use for the embossing, and would like to use "orbitron.dxf" font if that is available.

I'll be using an external library called `Write.scad` for the text embossing, along with the `orbitron.dxf` font. I already have these libraries in a "write" subdirectory within my OpenSCAD library path.

So, the parameters I need to be able to control are:

*   `millOuterDiameter`: The outer diameter of the mill.
*   `millInnerDiameter`: The inner diameter of the mill.
*   `wallThickness`: The thickness of the wall.
*   `bottomThickness`: The thickness of the base.
*   `innerWallHeight`: The height of the wall.
*   `edgesCut`: The size of the bevels on the top and bottom edges of the saucer.
*   `labelFont`: The font to use for the embossing.

I think that covers everything. Can you help me with this?

Hi, I'm looking to design a strain relief bracket for my 3D printer's X-axis. It's a Prusa i3 clone with an offset leadscrew setup, similar to the HIC Prusa design. Basically, when I tighten the X-axis belt, it puts strain on the Z-axis rods, which I want to avoid.

I need a bracket that clips onto the X-axis idler end piece and then pushes back against the X-axis smooth rods. It doesn't need to be a fancy tensioner, just something simple that redirects the force to the X-axis rods themselves.

Here are the key parameters I need it to be parametric in:

*   **Upper arm inside length:** (how far the upper arm extends inwards)
*   **Lower arm inside length:** (how far the lower arm extends inwards)
*   **Bracket inside height:** (the overall height between the arms)
*   **Bracket width:**
*   **Bracket thickness:**
*   **Nut/Screw Size:** (for M3 or M4 screws and captive nuts - I need the appropriate sized holes.)
*   **X-axis straight rod diameter:**
*   **Overhang Lip Depth:** (the lip that keeps the bracket attached to the idler)

I'd like to be able to adjust all of those. I'm using metric sizes and would like to keep it that way. I think for my current printer, I'm using 8mm smooth rods, M3 screws and nuts. I'm not 100% sure what the actual inside lengths or heights should be, but that's why I want it to be parametric, so I can iterate with the design until it fits correctly on my printer.

Could you generate the OpenSCAD file for this? I'm using the MCAD library, particularly `motors.scad`, `boxes.scad`, and `nuts_and_bolts.scad`.

Hey, I'm looking to design some steampunk-style goggles for a project. I have a couple of round, mirrored orange lenses from old sunglasses that I want to use, so the design needs to accommodate those. I've got some specific requirements for the design that I think are important.

First, the lenses are 47.5mm in diameter, and I'd like the pupil distance (the distance between the centers of the lenses) to be adjustable, but the default should be around 70mm. The main structure of the goggles, where the lenses sit, should be about 2mm thick for some structural integrity. The overall height of the lens holders should be around 50mm. I want a kind of sweeping, almost wing-like shape to the lens holders that angles back, and for that sweep I’m thinking maybe a radius of 2 times the lens diameter would work? The height of the part connecting the lenses should be about 10mm.

For the connection between the two lenses, I'd like a central bar that’s about 10mm tall and connects the lenses about 5mm below the top edge of the lens housing. And I’d like a smaller, secondary connector that is about 8mm in height. I was thinking maybe add a small decorative piece on top, like a small bar for more vintage look.

I'm also planning on having decorative caps that attach to the outside of the lens holders with some kind of interlocking tooth/gear mechanism. The caps should be about 10mm long, and I was thinking each should have 12 "teeth" that interlock with the frame, each tooth should be about 5mm diameter.

Finally, I want to include inner rings that can be used to secure the lenses from the back. They should be slightly shorter in height, maybe about half the length of the eye caps, and have a lip on the inside to help hold the lenses in place.

I need all of this done in OpenSCAD, so it can be easily modified by others. I'm not really interested in any kind of custom or complex modules, just the basics should do. The whole thing should be designed to be printable without supports. Use `$fn=128` for the circles to make them nice and smooth, please. And I'd like the design to be fully parametric, so things like lens diameter, pupil distance, thickness, cap lengths etc. can all be easily modified. It would be great if you could organize it in a way that the different parts are easy to find and modify too.

I'd like to design a customizable dice in OpenSCAD. It should be a standard six-sided die, but with a heart shape instead of the number 6. The user should be able to control the overall size of the dice (the distance between opposite flat faces) and the thickness of the numbers/heart on the faces.

Specifically:

*   The core shape is a sphere that's intersected with a cube to create the dice shape, so it has rounded edges.
*   The number '1', '2' and '3' are placed on three faces like normal. These should be text objects that are extruded.
*   The '6' should be replaced with a 2D heart shape that's also extruded.
*   The heart should be constructed from a square and two circles attached to the sides, rather than using the built-in heart function for better control.
*   All the numbers and the heart should be centered on their respective faces.
*   I need to be able to set the overall size of the dice as a parameter (let's call it `size`). This parameter will determine the overall size of the die and also affect the size of the numbers and the heart.
*   I also need to set the thickness of the numbers and the heart (let's call it `thick`).

Could you generate the necessary OpenSCAD code? It would be great if it's a single .scad file that I can run.

Hi, I'm looking to generate an OpenSCAD design for a coupler that connects a stepper motor shaft to a threaded rod. I'd like it to be fully parametric, so I can easily adjust dimensions to fit different motor and rod sizes.

Here are the main parameters I need to be able to control:

*   **couplerHeight:** The total height of the coupler. It will be split equally between the motor shaft and the rod.
*   **couplerExternalDiameter:** The outer diameter of the coupler.
*   **motorShaftDiameter:** The diameter of the motor shaft that will be inserted into the coupler.
*   **threadedRodDiameter:** The diameter of the threaded rod that will be inserted into the other side of the coupler.
*   **screwDiameter:** The diameter of the screws used to secure the motor shaft and rod.
*   **screwHeadDiameter:** The diameter of the screw heads.
*   **screwThreadLength:** The length of the screw threads.
*   **nutWidth:** The width across the flats of the nut used with the screws.
*   **nutThickness:** The thickness of the nut.
*   **halvesDistance:** The gap between the two halves of the coupler.

The design should consist of a cylindrical body. There will be a cylindrical cutout on one half for the motor shaft, and another cylindrical cutout on the other half for the threaded rod. Each side will have two radial screw holes for securing the motor shaft and threaded rod, respectively. The screws should include a cylindrical head and a nut on the opposite side. The coupler should be split in half with a small gap between the two halves.

I'm not looking for anything fancy here, just something solid and functional. I think that's everything. Let me know if you have any questions.

I'm looking to create a 24-hour word clock using OpenSCAD, and I'd like it to be parametric so I can adjust the dimensions easily. I'm thinking of a box-like design with a front plate where the words are cut out, a spacer behind that, and a backplate to hold it all together.

Here are the key specifications:

**Overall Dimensions:**

*   **Box Size:** The box should be rectangular, with adjustable X and Y sizes. Let's call these `X_SIZE` and `Y_SIZE`. It should also have a height, `Z_SIZE`.
*   **Character Spacing:** The space between the characters (LED locations) should also be adjustable, with `X_CHAR_SPACE` for horizontal spacing and `Y_CHAR_SPACE` for vertical spacing.
*   **Font Size:** The text size should be controlled by a `FONT_SIZE` variable.

**Construction:**

*   **Wall Thickness:** The box walls and front plate should have a consistent thickness, `WALL_THICKNESS`.
*   **Spacer Height:** The spacer that holds the LEDs behind the front plate should have a separate adjustable `SPACER_HEIGHT`.
*   **Corner Radius:** The box should have rounded corners with a radius controlled by `CORNER_RADIUS`.

**Text Layout:**

*   **Word Matrix:** The words to be displayed are arranged in a 2D array. Here's the array I'm planning to use:
```
    "ES#IST#VIERTELEINS",
    "DREINERSECHSIEBEN#",
    "ELFÜNFNEUNVIERACHT",
    "NULLZWEI#ZWÖLFZEHN",
    "UND#ZWANZIGVIERZIG",
    "DREISSIGFÜNFZIGUHR",
    "MINUTEN#VORBISNACH",
    "UNDHALBDREIVIERTEL",
    "SIEBENEUNULLZWEINE",
    "FÜNFSECHSACHTVIER#",
    "DREINSUND#ELF#ZEHN",
    "ZWANZIG###DREISSIG",
    "VIERZIGZWÖLFÜNFZIG",
    "MINUTENUHR#FRÜHVOR",
    "ABENDSMITTERNACHTS",
    "MORGENS....MITTAGS"
```
*   **Random Character Replacement:** The '#' characters need to be replaced with random letters (A-Z) each time the design is rendered.
*   **Font:** I'd like to use a stencil font. Specifically, let's use "Taurus Mono Stencil:style=Bold".

**Desired Output:**

*   **Parametric Design:** The code should use variables for all the key dimensions and parameters I've mentioned, making it easy to adjust.
*   **3D Model:** I need a complete 3D model of the word clock box.
*   **Separate Components:** I'd also like to have modules for generating individual pieces of the design: the front plate (2D and 3D), the spacer (2D and 3D), the back plate (3D), the box itself (3D) and cutouts to make the box using the components.
*   **Library Usage:** I am not expecting you to use external libraries. Please try to use the basic language.
*   **Comments:** The code should be clearly commented to make it easy to understand.

Could you generate the necessary OpenSCAD code to create this parametric 24-hour word clock?

Okay, so I'm looking to create a customizable toast stamp for Valentine's Day. I'd like to be able to put two lines of text on it, and ideally, have each line be up to six letters long. It would also be amazing to adjust the font for each letter individually, as well as the spacing between them. I also need the ability to mirror the text, so it stamps correctly on the toast. Finally, there should be some X and Y adjustment available to center the words properly.

Here’s a more detailed breakdown of what I'm after, please let me know if any clarification is needed:

1.  **Overall Shape:** The stamp should have a rectangular base with a rounded top, almost like a stylized speech bubble. The base would be solid, and the text should extrude from that base, creating the stamping surface.

2.  **Text Lines:**
    *   Two separate lines of text should be possible.
    *   Each line should support a maximum of six letters.

3.  **Letter Customization:**
    *   Each letter should have an independently adjustable font. I would want to pick from a predefined list of fonts such as "Open Sans Extrabold", "PT Serif", "Chewy", "Dancing Script", "Indie Flower", "Lobster", "Snowburst One", "Londrina Outline", and "Arial".
    *   The spacing between each letter should also be individually adjustable.

4.  **Text Positioning:**
    *   There should be X and Y adjustments available for each line of text, allowing for precise centering on the base.

5.  **Mirroring:**
    *   A mirroring option should exist for each line of text so that the words are stamped correctly and not backwards.

6.  **Libraries:**
   * I don't need any specific libraries for this. It should all be buildable with standard OpenSCAD operations.

7. **Dimensions:** I would like the total size of the stamp to be approximately 95mm x 92mm, with the text extrusion about 10mm. The text should be fairly deep at 13mm.

I think that covers everything. I'm hoping for a fully parametric OpenSCAD file(s) that will allow me to dial all of this in easily. Thanks!

I'd like to create a customizable lidded box, similar to the one described in that Instructables article, but with a few modifications. I'm aiming for a design where the box itself is separate from the lid, and the lid has a tab for easy opening.

Here's what I need:

*   **Parametric Design:** The key dimensions should be easily adjustable through parameters. This includes:
    *   `box_length`: The length of the box.
    *   `box_width`: The width of the box.
    *   `box_height`: The height of the box.
    *   `corner_radius`: The radius of the rounded corners of both the box and the lid.
    *   `wall_thickness`: The thickness of the box walls and the lid.
    *  `lid_thickness`: The thickness of the lid.
    *   `tab_radius`: the radius of the circular tab on the lid.
    *   `tab_thickness`: the thickness of the tab.
    * `tab_offset_from_edge`: How far the center of the tab is from the edge of the lid.
*   **Rounded Corners:** Both the box and the lid should have rounded corners using the minkowski function.
*   **Separate Lid:** The lid should be a separate piece from the box. It should sit on top of the box, so it should have a slight inset to fit over the box walls.
*  **Lid Tab:** The lid should include a circular tab on one side that is slightly recessed to allow a finger to grab it. The tab should be parametric in size and position, sitting a defined offset from the lid edge. It needs a cutout to clear the edge of the lid itself.
*   **Global Settings:** I need to be able to globally adjust the mesh resolution with `$fs` and `$fn`.

I'm not sure if this will need multiple files, so go ahead and structure it how you see best for customizability. I'm fine with it all being in one file if that's easiest. Could you generate that for me in OpenSCAD? I don't have any specific library requirements beyond basic functionality.

I'd like to create a customizable bookmark in OpenSCAD, with a text tag and an image head.

The bookmark should consist of two main parts: a rectangular tag with text engraved on it and a head piece attached to the tag, which will have an image on it.

Here are the parameters I'd like to be able to control:

**Tag Parameters:**

*   `text`:  The text to be engraved on the tag. I'd like to use a heart symbol, specifically ♥.
*   `length`: The length of the tag. I want to control this numerically.
*   `thickness`: The thickness of the tag.
*   `tag_color`:  The color of the tag.
*   `width`: The width of the tag, fixed at 15mm.
*   `gap`: Space between the edge of the tag and the start of the engraved text, fixed at 2mm.
* The text should resize to fit the tag, but I want to be able to control the size of the text. If the text would be too long, have the text use multiple lines vertically.

**Head Parameters:**

*   `head_thick`: The thickness of the head.
*   `head_height`:  The height of the image printed on the head.
*   `rotation`: The rotation of the image. I need to rotate the image by 0, 90, 180, or 270 degrees, which should be equivalent to right, top, left, and bottom, respectively.
*  `image`: The 15x15 image on the head, and it must be configurable.
*   `head_color`: The color of the head.
*   `head`: the size of the head, fixed at 15mm.

**Other:**

* I will be using a customizer and I want the image on the customizer to be at 1/4 scale and the one on the 3d to be 1/15 scale.
* I want to add a small fixed value of `0.2` of thickness to prevent 0 thick surfaces. This is not configurable.
* It is important that there are not any 0 or negative thickness values.

I'm hoping you can write the OpenSCAD code to achieve this. Please use the `surface()` module to add the image. I don't need any special libraries for this design, just the standard OpenSCAD functionality.

Hey, I'm looking for an OpenSCAD design for a twisted pot, something like a vase. I'd like to be able to adjust the height, width, and the amount of twist in the pot. It should also have a thickness parameter so I can control how thick the walls of the pot are.

Ideally, I'd also like to be able to add randomly placed holes through the pot's walls. I'd like to be able to control the thickness of the cylindrical hole makers and a 'poly' setting for the resolution of all curves and holes. So, I guess that means I'd have settings for enabling the holes, the thickness of the hole cylinders, and the resolution. I'd like the holes to be randomly rotated.

I don't have any particular preference for libraries, and I'm not expecting anything particularly advanced or optimized. I'm fine with just the core OpenSCAD functions. Could you generate the necessary `.scad` files for this?

Hey, I'm looking to design a custom slingshot, specifically a pickle fork style one, and I'd like it to be parametric so I can easily adjust the dimensions. I've been messing around with OpenSCAD, but I'm still pretty new to it.

Here's what I have in mind:

**Overall Shape:**
I want the slingshot to have a handle and two forks extending upwards. The forks should have a groove for the bands.

**Handle:**
*   I'd like the option to choose between a round handle or a more square/rectangular shaped handle.
*   The handle should have adjustable parameters for:
    *   **Depth**: How thick the handle is.
    *   **Corner Radius**: The radius of the rounded corners on the handle.
    *   **Handle Length**: The length of the handle.
    *   **Handle Top Width:** The width of the handle where it transitions to the forks. This would be the upper width if the handle is rectangular.
    *   **Handle Bottom Width:** The width or diameter of the handle at its base. This would be the base width if the handle is rectangular or the diameter if the handle is round.
*   I'd like to include an optional lanyard hole at the base of the handle that can be disabled using a parameter. I'd also like the lanyard hole to have optional rounding applied at each end.

**Forks:**
*   The forks should also be parametric, with controls for:
    *   **Fork Length:** The length of the forks.
    *   **Fork Outer Width:** The overall width of the forks.
    *   **Fork Gap:** The gap between the two forks.
    *   **Groove Depth:** The depth of the band groove.
    *   **Groove Width:** The width of the band groove.

I'd really appreciate it if the design is robust and user-friendly for parameter adjustment. I'd also like the design to be generated entirely from scratch, rather than modifying or improving on any existing code. I'm not using any libraries right now, but I'm open to using them if you think they'd improve the design. I'm just looking for the core slingshot design. Thanks in advance!

Hey, I'm trying to design a simple, parametric lid for a can using OpenSCAD. I've already had a go, but wasn't super happy with the results, so I'm starting over with a simpler approach.

The lid basically consists of three cylinders and a lip that I've made by rotating a polygon. I need to be able to control the diameter of the can it's designed for, the wall thickness of the lid, the lip thickness and height, a handle ratio for the small cylinder on the side, the overall lid height, and a lip Z adjustment, if needed.

So, the primary cylinder forms the main body of the lid, and a second cylinder is subtracted to create a cavity that would fit over the can. The third, smaller cylinder serves as a sort of handle/grip on the side. Then, the lip is created with a `rotate_extrude` of a polygon.

I'd like to control these parameters:

*   `canDiameter`: The diameter of the can the lid is designed for.
*   `lidWallThickness`: The thickness of the lid's main cylinder walls.
*   `lipThickness`: The thickness of the lip that grips the can.
*   `lipHeight`: The height of the lip.
*  `handleRatio`: a ratio of the canDiameter used to define the grip cylinder diameter.
*   `lidHeight`: The overall height of the main lid cylinder (not including the lip).
*   `lipZAdjustment`: An adjustment to the vertical position of the lip.

Could you generate a parametric OpenSCAD file for me that does this? The file should define all the parameters mentioned as variables at the top, and the code should build the lid using those parameters. I'm using OpenSCAD so no libraries are required as far as I can tell.

[Assistant]
CanLid_v2.scad:
```
canDiameter = 86.4;
lidWallThickness = 1;
lipThickness = 0.35;
lipHeight=2;
handleRatio = 0.25;
lidHeight = 5;
lipZAdjustment = 0;
$fn=60;

union() {
    translate([0,0,(lidWallThickness+lidHeight)/2])
    difference() {
        cylinder (h = lidWallThickness+lidHeight, d = canDiameter+lidWallThickness, center=true);
        translate([0,0,lidWallThickness/2])
        cylinder (h = lidHeight+0.1, d = canDiameter, center=true);
    }

    translate ([-canDiameter/2,0,lidWallThickness/2])
        cylinder (h = lidWallThickness, d = canDiameter*handleRatio, center=true);

    translate([0,0,lidWallThickness+lidHeight-2+lipZAdjustment])
    rotate_extrude(angle = 360, convexity = 2)
    polygon( points=[[canDiameter/2,2],[canDiameter/2-lipThickness,2-lipHeight/2],[canDiameter/2,2-lipHeight]] );
}

Hi, I'm looking to design a magnetic endstop for my Kossel delta printer, specifically a z-probe. I've seen a few designs out there, but I want something that is easily customizable and uses parameters. I’ve included a description of the design that I like, along with some parameters and modules I'd like it to include. The design is based on a remix of a zero offset probe by a user named "paul_delta," but it’s modified to be lower, lighter, and with a low activation height. It uses magnets for attachment, which I'd like to have parametrized so I can change the magnet size easily.

The overall concept is a bridge-like structure that holds the probe pin and attaches to the delta effector via magnets. There's an upper and lower bridge part, and a probe holder that connects them. I want to be able to print just the probe pin separately too.

Here’s a breakdown of the parameters I’d like to be able to control:

**General/Part Selection:**

*   `Print`: A string variable that determines what gets printed. Options should be "probe" (the full z-probe), "pin" (only the probe pin), "both" (the full z-probe and the probe pin separately), and "nopin" (z-probe body without the probe attachment).

**Probe Holder Dimensions:**

*   `height`:  Overall height of the assembly.
*   `depth1`: Depth (thickness) of the bridge part.
*  `depth2`: Depth of the probe holder part.
*   `length1`: Width of the upper bridge.
*   `length2`: Width of the lower bridge.
*   `length3`: Width of the probe holder, needs to be adjustable based on probe pin radius and clearance.
*   `offset`: The effector offset for the delta.
*   `savematerial`: A factor for material saving/removal (this should be a multiplier on dimensions for cut-outs).
*  `magnetdia`: Magnet diameter, for the cutouts
* `magnetdepth`: Magnet depth for the cutouts.
*   `magnetsep`: Separation between the magnets on the effector.

**Probe Pin Dimensions:**

*   `r_probe`: Radius of the probe pin, needed for both the pin itself and the hole in the probe body.
*   `d_probe`: Thickness of the probe pin, also used for the shape of the lower part of the pin.
*   `h_pin`: Height of the probe pin.
*   `clearance`: Clearance between probe pin and the probe hole.

**Hidden (fine-tuning):**

*   `$fs`: Minimum segment size.
*   `$fa`: Minimum angle for segments.

I'd also like these modules:
* `holder()`: Generates the endstop holder.
* `probe_pin()`: Generates just the probe pin.
* `probe_cut()`: Generates the cut in the z probe for the pin

Can you generate the necessary OpenSCAD files to accomplish this? I would prefer using BOSL2 or similar if you would like to include any existing libraries.

Okay, I'm looking for a way to generate leaf-like structures in OpenSCAD, something that's both customizable and visually interesting. I have a few ideas I want to explore.

Basically, I want to start with a central stem, and then have branches coming off of that, which can themselves have further branches. I'd like parameters to control:

*   The starting diameter and length of the main stem
*   The angle of the main stem (maybe a slight curve?)
*   The positions along the main stem where branches come off
*   The angles of these branches
*   The scaling of subsequent branch levels
*   And finally, a minimum diameter for any branches, so it doesn't keep generating infinitely small ones.

I'd like to have the option to render just the vein structure, or a solid leaf shape. If I choose the solid leaf, I'd like it to be created by extruding the 2D outline of the vein structure. Also, I'd like to have a kind of "skeleton" option when rendering the solid leaf - where the inner shape is cut out to leave a brim and veins.

I think the best way to handle the solid leaf is to create a 2D version of the veins structure and use `linear_extrude` to make it 3D. This would mean having `rod`, `veins` and `veins2D` modules, and likely a `base` module to create the extruded shape. There would be separate `petal` module controlling which elements are included.

I imagine all of the above using modules, and that you'll provide the final instantiation to generate the model.

I need this to be parametric and easily adjustable. I also want a good user interface with comments showing the minimum, maximum and default values of the configurable variables.

I'm looking to design a fully parametric quadcopter, and I'd like your help generating the OpenSCAD code. I'd like to be able to output STL files for individual parts or see a preview of the whole thing.

Here are the parameters I need to control:

*   **Output Object:** An integer that selects which part to generate (0 for preview, 1 for motor mount, 2 for main plate, 3 for bottom plate, 4 for top plate, 5 for landing gear, and 6 for arms).
*   **Arms Material:** A string defining the material for the arms ("peru" for wood, "gray" for aluminum, "black" for carbon, or 0 for printed).
*   **Print Material Color:** A string for the color of printed parts ("red", "orange", "yellow", "green", "blue", "pink", "purple", "brown").
*   **Thickness:** The general thickness of many components.
*   **Arms Height:** Height of the arms.
*   **Screw Holes Size:** Diameter of the screw holes.
*   **Quadcopter Size:** Overall size of the quadcopter (from 100 to 1000).
*   **Plate Thickness:** Thickness of the main plates.
*   **Main Plate Size:** Size of the main plate (from 10 to 500).
*   **Main Plate Extra Size:** Extra size added to the main plate.
*   **Top Plate Size:** Size of the top plate (from 0 to 500, 0 means no top plate).
*   **Vibration Dampener Holes Size:** Diameter of the vibration dampener holes.
*   **Motor Mount Thickness:** Thickness of the motor mounts.
*   **Motor Diameter:** Diameter of the motors (from 5 to 100).
*   **Shaft Hole Size:** Diameter of the motor shaft hole.
*   **Motor Bolt Holes Size:** Diameter of the motor bolt holes.
*   **Motor Bolt Holes Distance:** Distance of the motor bolt holes from the center.
*  **Landing Gear Thickness:** Thickness of the landing gear.

I need to be able to produce the following components:

*   **Motor Mount:** A mount to attach the motors, with holes for bolts and the motor shaft.
*   **Main Plate:** The main structural plate, with optional extra size and rubber band attachment points.
*   **Bottom Plate:** A structural plate, meant to be mounted below the main plate.
*   **Top Plate:** An optional plate above the main plate, with holes for vibration dampeners.
*   **Landing Gear:** Legs for the quadcopter to stand on.
*   **Arms:** The arms that connect the motors to the center plates.

I think that should cover everything. Let me know if you have any questions. I'm hoping for a fully parametric design, so I would want that to be reflected in the code. I don't have any preferences for libraries, but I assume you'll probably need to use one. Also, this is my first time doing this, so please be sure to make it easy for me to understand!
