Okay, I need to design a parametric plug for a hole, something like the one I already have but I want it totally re-written. I've attached the SCAD code for the plug I'm currently using, named "Parametric_Rig_plug_v5_paramaterized.scad".

The key aspects of the design are:

*   **Bottom Plug:** This is the part that actually goes into the hole. It has a tapered shape, starting with a smaller diameter at the bottom and flaring out to a larger diameter. I need to be able to control the starting diameter, the height of the bottom plug, and the taper angle (using a ratio).
*   **Base Plug:** This sits on top of the bottom plug and forms a kind of shoulder. It's cylindrical, and I need to be able to control its height and diameter. The diameter is bigger than the top diameter of the bottom plug.
*   **Stem:** This extends from the base plug, with a uniform diameter along its height. I need to be able to control both its diameter and height.
*   **Ball:** A spherical part at the top of the stem. Its diameter needs to be controllable, but it's usually going to match the stem diameter.
*   **Lower Belt:** This is a ring that sits between the base plug and the bottom plug, to help keep it in place.
*   **Upper Belt:** Another ring, this one sits higher up, near the top of the stem. This one also keeps it in place.

I'm looking for a fully parametric design, so I want to control all the critical dimensions with variables. The attached file should give you a sense of how I'd like those parameters laid out. I'd really like all those calculations to be part of the file, so I don't have to deal with it myself. I'd like the echos at the end so I can easily check the dimensions. I need the $fn to be parametrically controllable, too. I think we can make it 50 by default though. I'd prefer if you used the `rotate_extrude` function to create the belt objects, rather than just cylinders.

I'm not using any special libraries for this, so let's keep it in core OpenSCAD.

I'm looking to design a snap-fit mechanism for 3D printing, and I'd like it to be configurable through OpenSCAD. I have some basic parameters in mind, but I'd like the design to be flexible enough to adjust these and others.

Specifically, I need a mechanism consisting of two parts: a "snap" part with flexible arms and catches, and a "bracket" part to receive it. I need parameters for:

*   **Mounting Centers:**
    *   The distance between the centers of mounting holes on each part (`mount_cc_dist`). This should be the same for both pieces.
    *   The width of the mount, measured between the outer edges of the mounting screws (`mount_cc_width`). This should be the same for both pieces.

*   **Thickness:**
    *   The base thickness of the main parts (`thickness`).

*   **Mounting Hardware:**
    *   The diameter of the mounting screw (`screw_dia`).
    *  The diameter of the screw head (`screw_head`). I understand there should be a function relating `screw_dia` and `screw_head`.
    *   A screw head land, measured as an offset from screw diameter on the outside of each screw head (`screw_land`). I understand this should be a function of `screw_dia`.

*   **Tolerance:**
    *  A general tolerance gap for all parts (`gap`).

*   **Snap Mechanism:**
    * The width of the snap mechanism itself, not including the mount (`snap_width`). I understand this should be a function of `mount_cc_width` and other parameters.
    * The width of the catch on each arm (`catch_width`). I'd like this to be a fraction of `snap_width`.
    *  The width of the flexible bar in each snap arm, between the mount and catch (`snap_bar_width`). I'd like this to be a function of `snap_width` and `catch_width`.
    *  The minimum width of the catch, for a rounded form (`catch_min_width`). This should be a fraction of `snap_bar_width`.
    * The length of the catch, how far it projects (`catch_length`). I'd like this to be a function of `mount_height` and `mount_cc_dist`.
    * A constant `d` used in some areas of construction.

The snap arms should have a rounded or filleted profile where they flex, and the catches should be nicely rounded as well, with the tips angled inward a bit to help them flex. The mounting screw holes should include both the screw diameter hole and a countersink for the head.

I need the design to be generated as two separate modules within the same OpenSCAD file: `snap()` for the part with the flexible arms, and `bracket()` for the receiving part. It would also be helpful if the output is easily viewable with different orientations, so please include the `demo` and `both` views as described in the original code.

I don't need any specific libraries, but I am fine with you using helper modules if you think it will make things simpler. Just make sure everything is contained within one file. Thanks!

I'd like to design a parametric base for mounting a small 5.8Ghz TV to an RC controller. I have a basic idea from a previous design (attached), but I'd like something cleaner and more flexible. I need it to be easily customizable via parameters.

The main body should be a rectangular platform with an inner cavity for the TV. This cavity will have a floor with reinforcing ribs. I need to be able to adjust:

*   The inner dimensions of the rectangular platform (length and width).
*   The wall thickness of the platform.
*   The height of the platform walls.
*   The height and width of the reinforcing ribs.
*   The thickness of the floor.
*   The number of divisions/rooms the ribs create along the length and width.

I also need mounting holes. These will be for M4 screws, and should be countersunk. I need:

*   The distance between the mounting holes along one side.
*   The spacing between alternative mounting holes along the same side.
*   The diameter of the mounting holes.
*   The diameter of the countersunk head.

There also needs to be a way to mount snap clips to the sides (like the ones from the thingiverse link, but I don't need help modeling the snap clip itself). These will be mounted with small screws, and I will need to be able to adjust:

*   The screw diameter for mounting the snap clips.
*   The screw length for the snap clips.
*   The overall width of the snap clip flange.
*   The width of the main body of the snap clip flange.
*   The height of the snap clip flange.
*   The spacing of the snap clip mounting screws.

Finally, it would be great if there were optional pads on the bottom corners to help prevent warping. I'd like to be able to set the:
*   Diameter of these pads.
*   Height of the pads.

I want the design to be parametric, so I can easily adjust the dimensions for different TV sizes and mounting setups.

I think using BOSL2 would be really useful for managing the parameters and some of the more complex shapes.

Could you generate the necessary OpenSCAD file(s) for this?

I'm looking to create some parametric mounting brackets for my multicopter. I've got a design in mind that uses twin tubes as the base for mounting various components. My current setup uses 10.1mm diameter tubes spaced 110mm apart, center to center. I want the ability to create three different types of mounts: a dual mount that connects to both tubes, a single mount for just one tube, and a servo mount.

For all the mounts, I'd like to have these parameters:
*   `mount_tube_dia`: This is the diameter of the tubes themselves, currently 10.1mm.
*   `mount_tube_dist`: The center-to-center distance between the tubes, currently 110mm.
*   `mount_width`: The width of the mounting clamp, I'd like to set this to 12mm by default.
*  `mount_wall`: The wall thickness of the mount, let's start with 3mm.
*   `screw`:  The diameter of the mounting screw, M3 is 3.0 and M2.5 is 2.5,  defaulting to 3mm.
*   `nut`: The size across flats for the nut, using 5.5mm for M3.
*   `nut_h`: The nut height, 1.5mm for M3.

Here's how I envision the three specific mount types:

1.  **Dual Mount:** This mount should connect to both tubes and extend outwards at an angle. I need parameters for:
    *   `mount_offset`: The distance from the centerline of the tubes to where the angled section starts. I'd like a default value of 28mm.
    *   `mount_angle`: The angle at which the mount extends outwards from the tubes. I think a default of 65 degrees is good.

2.  **Single Mount:** This mount should connect to only one tube and extend outwards along the same plane. It should have a parameter:
    *   `mount_offset`: The length the mount extends from the tube center. The default value of 40mm should work.

3.  **Servo Mount:** This mount attaches to a single tube, but has a flat area with holes designed to mount a standard servo. I need these parameters for this:
    * `servo_flange_width`: The width of the servo mounting flange, default 35mm
    * `servo_screw`: The diameter of the servo mounting screw, default 2.5mm
    * `servo_flange_height`: The height from the tube to the bottom of the servo flange, let's start with 20mm.

For all mount types, there will be a gap between the clamping portion and the mounting flange. This needs the parameter:
*   `mount_gap`: The size of the gap, should be 1mm.

I'd like all the mounts to use a nut and screw to clamp to the tube. The nut should be captured within the mounting flange.

Could you generate the OpenSCAD code for these three types of mounts? It would also be ideal if I could select the `mount_type` from "dual", "single", and "servo". I don't need the nut_cage module separately from the rest of the code. It might make sense to use `hull()` or a similar function to create some of the solid shapes so the code looks clean. I don't need to use any external libraries, just the core OpenSCAD functions.

I'm trying to design a customizable Christmas ornament, and I'm having some trouble figuring out how to get certain inputs working correctly, specifically around text and color choices. Here's what I'm imagining:

The main shape should be a globe with a hoop at the top for hanging. The globe should have text written on its surface, something like "Merry Christmas," but I'd like to be able to adjust the text, its position, and possibly its font later.

Inside the globe, I want a winter scene. This scene should include:

*   A variable number of snowmen (I'm thinking from 0 to 5), each with an option to be either a "man" or a "woman" (represented by a hat style)
*   A Christmas tree
*   A few wrapped presents.

I need to be able to set the text for a name and a year to be part of the scene inside the globe, as well. I want to adjust the scale of this text.

Also, I want to control some colors, ideally with an on/off toggle. I'd like to be able to control the color of:

*   The main body of the ornament (globe and hoop).
*   The text on the outside of the globe.
*   The snowmen's hats and buttons.
*   The overall scene inside the globe.
*   The ribbons on the presents.
*   The tree.
*   The year and name text in the scene.

Finally, I need to have a toggle for "enableSupport." If that is set to "Yes," I need supports under the hoop for the ornament to print correctly.

I'd like this all to be controlled with parameters in a customizer, if that's possible. The text input is the most problematic thing I'm dealing with, so I would like that to work correctly.

I would also like to use the `Write.scad` library to handle the text.

[Assistant]
ornament_v2.3.scad:
```
use <write/Write.scad> ;
/* [Text] */

// Or any message
nameText = "MakerBot";

// May need to adjust this to make nameText fit nicely
nameTextScale = 7;

/* [Snowmen] */

// Adjust for family size
numberOfSnowmen = 5; // [0:5]

// Largest Snowman
snowmanOneGender = 1; // [1:Man,0:Woman]

snowmanTwoGender = 0; // [1:Man,0:Woman]

snowmanThreeGender = 0; // [1:Man,0:Woman]

snowmanFourGender = 1; // [1:Man,0:Woman]

// Smallest Snowman
snowmanFiveGender = 0; // [1:Man,0:Woman]

/* [PrintSettings] */

// You may need if you arn't printing with generated support (That's how I printed)
enableSupport = "Yes"; // [Yes,No]

/* [Year] */
yearText = 2015;

/* [Hidden] */

// Going to upload a dualstrusion version sometime.
//enableDualPrint = 0; [0:No,1:Yes];

// A few different things to toggle on and off when playing with dual extrusion
// Set the colors to 1 that you want on, and to 0 to subtract the items
// Note, if you place scene objects overlapping, the colors may not subtract correctly causing an overlap
// (eg. if you embedded one present into another and turn off primary scene color or ribbon color)

// I think main body,ribbon, and year text in a bright color, with the rest being in an off white looks great!
color1 = 1; // Main body
color2 = 1; // Globe text (Text on out side of globe)
color3 = 1; // Snowmen hats and buttons
color4 = 1; // primary scene color
color5 = 1; // Presents ribbon
color6 = 1; // Tree
color7 = 1; // Scene text  (Text that's part of teh scene)

I'm looking to create a customizable pegboard holder system, and I'd like your help designing it in OpenSCAD. I need the design to be parametric so I can easily adjust different aspects of the holders. The goal is to be able to create holders for tools, parts, or even display objects.

Here's what I'm envisioning:

*   **Holder Shape and Size:**
    *   The holders should be generally rectangular with rounded corners. I need to be able to specify the width and depth of the opening (the "orifice" as the attached code calls it) which I'll call `holder_x_size` and `holder_y_size`, and also a `holder_height`. I also need to be able to round those corners off using `corner_radius`.
    *   I need to be able to specify the number of holders along the x and y axes, `holder_x_count` and `holder_y_count`.
    *   I also want to be able to taper the bottom of the holders using `taper_ratio`.

*   **Wall Thickness and Reinforcement:**
    *   The thickness of the walls of the holder should be adjustable (`wall_thickness`).
    *   I also want to control how much of the holder is reinforced at the base, using `strength_factor`. I also need to be able to specify if the bottom of the container is closed (using `closed_bottom`).

*   **Pegboard Attachment:**
    *   The design needs to include pegboard attachment pins or clips. I'm using US-style pegboard with 1-inch spacing (25.4mm) and 1/4-inch holes (6.0035mm). The board itself is 5mm thick. This spacing and hole size, with the board thickness, should be parameterized so it can be changed if need be but should default to the mentioned US standards.
    *   The attachment clips should be able to have an optional lip feature which allows the holder to grab onto the pegboard securely.

*   **Advanced Options:**
    *   I need an offset from the pegboard surface using `holder_offset`.
    *   I need to be able to specify an angle for the holder relative to the pegboard, using `holder_angle`.
    *   I need to be able to cut a percentage of the side of the holder, using `holder_cutout_side`. This will allow for objects to be placed into the holders from the side.

I've attached a sample OpenSCAD file as an example, but it would be great if you could create a new clean version with better structure.  I would prefer it if the code didn't calculate dimensions based on variables defined elsewhere. I'd also like the `round_rect_ex` module to be simplified to just take the outside dimensions of the round rectangle. That way it'd be easier to conceptualize and use.

Also, please don't include a logo, that's not necessary for my use case.

I want a parametric OpenSCAD file or files, such that they do not rely on any external libraries besides the standard OpenSCAD library. It would be preferable to have one main file that includes all the modules and logic.

Hi, I'd like to design a little clip for holding LED strips, and I think I need your help with OpenSCAD. I want it to be parametric, so I can easily adjust it for different strip sizes and mounting methods.

Basically, the clip needs to have a channel for the LED strip itself, and then a way to mount it, probably with a screw or nail hole, but I'm open to suggestions there.

For the strip channel, I was thinking it should be a simple rectangular cutout that matches the strip's width and thickness, plus some wiggle room. I'm initially thinking about a strip with a width of about 16.5mm and thickness of 4mm. Let's call this `strip_width` and `strip_thickness` in the code.

The mounting part is where it gets more interesting. I envision a small tab extending from the main body of the clip with a hole. I'd like to be able to control the overall length of the clip (including the tab), which I'm calling `clip_length`, and the tab extension itself (`tab_length`). I'd also like to have the hole's diameter, which is `hole_diameter`. I'd like this part to be round, maybe a cylinder at first, and I'd like to be able to set the diameter. The whole thing will need to be thick enough to be durable, let's say `clip_thickness`. Let's make that the same thickness as the LED strip plus a bit more, say 5mm. So maybe `clip_thickness = strip_thickness + 1` as the default.

I was also thinking maybe to make the base of the clip thicker so it's a bit more sturdy in that region. Let's call this `base_thickness`. Perhaps that could be double `clip_thickness` by default.

And I'd also like some wiggle room for the nail. So let's make the hole diameter a bit bigger than the nail.

I think it might be helpful if we also have a parameter for the size of the screw/nail itself, let's call it `nail_diameter`, so we can use that to control the actual hole size and allow some wiggle room as well. I'm not quite sure how much wiggle room to allow, but maybe something like `hole_diameter = nail_diameter * 1.25` as the default.

Could you generate a basic parametric OpenSCAD file for me? I'd like all of the dimensions to be adjustable by variables, and would like to avoid hardcoded values.

Also, I'd like to use the `BOSL2` library, so I don't have to code from scratch. Thanks!

I'd like a parametric OpenSCAD design for a bed level test pattern, similar to a spiral but with some key differences and more flexibility. I need it to be able to generate both rectangular and circular spiral patterns, controlled by a parameter.

For the rectangular pattern, I need control over the bed's width and length, the thickness of each printed line, the height of the lines, the spacing between the lines, and the number of "loops" or passes across the bed. I'd like the rectangular spiral to actually be a series of concentric rectangles, not a true spiral - so each 'loop' would be a rectangular path, starting from the outside and spiraling inward towards the center.

The circular pattern needs similar control: radius of the bed, line thickness, line height, spiral spacing, and number of loops. And similar to the rectangular version, the circular version should consist of concentric circles rather than a true spiral curve, again starting from the outside and going inwards.

I'm envisioning these parameters:

*   `bed_type`:  Either "rectangular" or "circular" (or perhaps an integer like 4 for rectangular and 120 for circular, if it's easier internally).
*   `bed_x`: Width of the rectangular bed (only used if `bed_type` is "rectangular").
*   `bed_y`: Length of the rectangular bed (only used if `bed_type` is "rectangular").
*   `bed_radius`: Radius of the circular bed (only used if `bed_type` is "circular").
*   `line_width`: Thickness of each printed line.
*   `line_height`: Height of the printed lines.
*   `spiral_gap`: Distance between each loop.
*   `loops`: Number of loops in the pattern.

I'd prefer the output be a single SCAD file if possible. I don't need any fancy features, just the ability to generate this basic test pattern. I'm not expecting any dependencies on external libraries.

I'd like to design a hanging herb container rack that can be attached to a shelf. I want to avoid drilling or gluing, so the design will use a board that's already part of the shelf to secure it. The rack should hold multiple small, cylindrical containers in a grid pattern, and I'd like the dimensions and layout to be easily customizable.

Specifically, I need a design where the containers are held by individual hexagonal frames, with a U-shaped profile at the top that fits snugly around the board of the shelf. The hexagonal frame should have a small base plate for added stability.

The parameters I'd need to adjust are:

*   **`container_diameter`**: The diameter of each container.
*   **`container_height`**: The height of each container.
*   **`board_thickness`**: The thickness of the board the rack will attach to.
*   **`wall_thickness`**: The thickness of the material used for the rack itself.
*   **`number_of_columns`**: The number of container columns.
*   **`number_of_rows`**: The number of container rows.

The containers should be arranged in a grid, but with an offset for every other row. So the second row is offset halfway relative to the first row, the third row is lined up under the first and so on.

I think that's all the parameters. Could you generate the necessary OpenSCAD files to achieve this? I'm not using any external libraries or modules right now. I want all files to be created from scratch.

I'm looking to design a Z-wobble suppressor for my 3D printer, similar in concept to the one I've been using, but I need a parametric version. I want to be able to adjust several key dimensions, and I think it would be useful if it was designed in a way that makes it easy to change things up for other printers.

The basic design is a plate that mounts to the Z-screw, with an arm extending out from it to the side. This arm should reach the makerslide channel on my printer, and it uses a relatively simple design. Specifically, I need to be able to control the following:

*   **`height`**: The overall height of the suppressor.
*   **`thickness`**: The thickness of all the parts, which is determined by the width of the makerslide gap.
*   **`mount_width`**: The width of the plate that mounts to the Z-screw.
*   **`offset`**: The offset between the mount plate and the arm.
*   **`arm_length`**: The length of the arm that extends towards the makerslide.
*   **`hole_diameter`**: The diameter of the mounting screw holes.
*   **`hole_separation`**: The center-to-center separation between the mounting screw holes.

The mounting plate should have two holes for screws. The arm attaches to the side of the plate and should be connected in a smooth and solid manner so that there are no stress points along the connection.

Could you generate the OpenSCAD files for this? I am envisioning this as a single file, but let me know if you think it's better to break it up into multiple files. I would like to use the BOSL2 library if possible, but feel free to use other libraries that would make things easier.

Thank you!

I'd like a design for a parametric box with hexagonal cutouts, sort of like a honeycomb pattern. I've seen some designs like this before, but I want a version that maximizes the amount of open space by putting the holes right up to the edges, even the corners, and also adds angled support under the horizontal surfaces so I don't need supports when printing.

Here are the parameters I want to be able to adjust:

*   **box_width**: The width of the box.
*   **box_length**: The length of the box.
*   **box_height**: The total height of the box.
*   **wall_thickness**: The thickness of the walls of the box and lid.
*   **hole_diameter**: The diameter of each hexagonal hole, measured point to point.
*   **hole_spacing**: The space between each hole.
*   **lid_clearance**: The space between the lid and the box.
*   **support_angle**: The angle of the support under the lid and horizontal surfaces of the box (like the floor).
*   **lid_height**: The height of the lid itself.
*   **grip_width**: The width of the grip on the lid, as measured from the edge of the lid.
*  **grip_thickness**: The thickness of the grip on the lid.

I want the design to include both a box and a lid. The lid should fit snugly onto the box, accounting for the `lid_clearance`. The cutouts should be created automatically based on the other parameters, so they cover the entire surface. The support angles should prevent overhangs during printing. I'm also aiming for a clean look, so make sure the edges line up properly.

I don't have any existing code for this - it'll all need to be from scratch. I'd like it if the generated code used the BOSL2 library to help simplify things. I guess I will be importing and using `BOSL2/std.scad`.

I need a parametric stand for a cylindrical object, like an e-cigarette. I'd like to be able to customize several aspects of the design.

First, the core of the stand should have a cylindrical hole. I need to specify the diameter and height of this hole.

Then, the stand itself will have some thickness around the hole. I'd like to control that thickness, as well as an additional, separate thickness value on the top edge of the cylinder, which will affect how the legs connect to the top. This top thickness can be positive or negative to create different looks.

The stand needs to have legs. I need to specify the number of legs, the distance of each leg base from the center, the diameter of the leg base, and how much space there is under the middle of the stand.

Finally, I want some rendering options. I need the ability to cut the model in half for a cross-section view, rotate the model, and add a tolerance value to slightly enlarge the hole diameter, which can be helpful for printing. I also want to control the resolution of round objects.

I'm thinking this will be a single OpenSCAD file with all of these parameters defined. I don't think any external libraries should be needed, but I'll let you decide if you need any.

I need a cable clip designed, but I want it to be customizable and mountable.

Here's what I'm thinking:

The clip should have a circular opening for the cable. I need to be able to define the radius of that opening, as well as the overall wall thickness of the clip. The clip should also have a height.

I'd like the design to include a mounting method, something I can screw down to a flat surface. A simple screw hole will do, but I want to be able to define where that mounting hole sits relative to the main cable channel.

So, ideally the OpenSCAD file should allow me to specify:

*   `cable_radius`: The radius of the cable opening.
*   `wall_thickness`: The thickness of the clip's walls.
*   `clip_height`: The overall height of the clip.
*   `mount_hole_offset`: How far the center of the mounting hole is from the center of the cable channel.
*   `mount_hole_radius`: The radius of the mounting screw hole.

For the basic shape, I'm picturing a cylinder as the outer form, with a flat face on one side to allow for mounting, and the cable opening in the center. The mounting hole can be a simple cylinder that cuts through the mount face. I'd also like the whole design to be built using `hull()`.

I am okay using functions from the BOSL2 library.

I'm looking to create a decorative Christmas ornament based on the Fibonacci spiral patterns you see on things like pinecones and sunflowers. I've seen some examples where people use OpenSCAD to make these, and I'd like to do something similar but with a few specific features and parameters.

Essentially, I want a spherical base, and then I want to generate a series of "petals" or "scales" that spiral around it using Fibonacci angles. I'd like these petals to be cone-shaped, starting from a point at the sphere's surface and expanding outward.

Here's what I'm thinking in terms of parameters:

*   **`ball_radius`**: This would control the size of the main sphere.
*   **`petal_size`**:  This would control the overall size/length of the cone shaped petals.
*  **`petal_base_size`**: This would control the size of the base of the cone petals, where they meet the sphere.
*   **`twist_factor`**:  This would determine the overall "tightness" of the spirals. A higher number would make them spiral more rapidly.
* **`num_spirals`**:  This should be adjustable so I can change how many spirals are generated.
*   **`fixation_position`**:  This controls the height (z-axis position) of a mounting or fixation point on the bottom of the sphere.
*   **`fixation_size`**: This would control the size of the fixation point, which should consist of a disk and a small cylinder underneath.

The model should do a boolean difference, subtracting the inner sphere from the outer sphere before adding the petals, as in the example I saw online.

Could you generate OpenSCAD code that accomplishes this? I don't need any special libraries, just standard OpenSCAD features.

I'd like to get some help creating a parametric OpenSCAD model for a Futaba S3004 servo, similar to the one I found online, but with a few more options and a bit more control. The goal is to be able to use it both as a 3D model and for generating 2D projections for laser cutting. I've got some specific ideas in mind.

Firstly, I need the servo body to be parametrically defined, with overall dimensions for the box shape, and also dimensions for the mounting flanges, their hole sizes, the shaft, and the wire gland. I need control over the position of the flanges and all the other features as well.

For the flanges, I want to be able to choose if the holes are for bolts or pilot holes for wood screws, so I need to have a parameter to switch between the two hole sizes. I also need to be able to specify the bolt hole diameter, screw hole diameter, and pilot hole diameter. I'll also need to set the spacing of the holes from the edges of the flanges.

The shaft needs to be parametrically adjustable for both cylinder and the taper/stepped area. I want to control the diameter of the cylinder, the diameters of each end of the taper, and the length of both cylinder and taper. The position of the shaft along the X axis from the edge of the box is important as well as along the Z axis.

The wire gland is basically a rectangular cuboid and I need to be able to adjust its dimensions, and its position along X and Z axis. I would also like to be able to control a parameter to adjust whether or not to include the wire gland in the model.

I also need the servo horn, with adjustable parameters for the overall width and height of the horn, the arm width, and also the radius of the cylindrical ends. It's important that I can position the horn relative to the servo body's shaft and also turn the horn on and off.

For generating 2D projections, I want a way to control the scaling of the projection, so I can adjust the size of the hole for laser cutting, by setting a percentage.

I'd also like to choose the origin point, either at the center of the servo, the center of the shaft, or the center of the flange. Also I need to be able to turn the flange holes on and off for laser cut projection.

The original model had a `hornZoverB` parameter, which seemed a little weird, since I'd expect the horn's vertical position to be relative to the shaft. I would like the horn vertical position to be determined by the vertical position of the shaft, and then the height of the horn above the shaft.

Finally, I'm hoping that the code can be flexible enough that all these parameters are well-defined and clearly laid out. Also it would be nice if the code had a module for each major feature; body, flange, shaft, horn, wire gland.

I'm not attached to any specific libraries, so just use what you think would work best.

This library produces a fotuaba S3004 futaba servo or a projection for cutting

The scale of the projected hole for the body can be adjusted below

It can be used in other models by calling:

The library can also produce a 2D projection that is useful for making a cutout for

I'm looking to create a parametric IPD (interpupillary distance) adapter for the Oculus Rift DK2 using OpenSCAD. This adapter will hold B lenses and will require a slight modification of the DK2 lens housing, which I will handle myself.

The design should allow for adjustments of the IPD from 59.5mm to 67.5mm, incrementing from -2 to 2 in millimeters (the provided code uses a variable called `ipd_incrase` for this). I'd like the final result to be two separate adapter pieces, one for the left eye and one for the right, that are mirror images of each other. The model should be relatively smooth, using a `model_resolution` variable to control the number of facets when creating arcs (with a default value of 360).

Here are some details on the individual components the design should have:

**Base Rings:** The main body of each adapter should consist of a ring with an outer diameter of 59.5mm, an inner diameter of 54.9mm, and a thickness of 2.9mm. It will need to be constructed using a `ring` module.

**Tab System:** There should be three tabs equally spaced around the base ring to hold the adapter in place. These tabs are created using a `tab` module, which should include a small cylinder feature at the tip of the tab. The tabs are then positioned with the help of a `tab_set` module which should ensure the tabs are properly placed on the main ring. I will also need a small cutout in the main ring where the tab attaches.

**Clip System:** Additionally, there should be a clip mechanism around the outside of the ring that will hold the lenses in place, implemented by the `clip` and `clip_set` modules. These clips also need to be spaced around the outside of the base ring.

**IPD Adjustment:** A secondary ring with an outer diameter of 64.5mm and an inner diameter of 55.3mm will be used for IPD adjustments. It has a thickness of 2.9mm, and should be displaced by the `ipd_incrase` variable along the y-axis. The `cut_set` module should make a cut around the secondary ring at an angle.

**Cutout:** Finally a cutout at a 97 degree angle will be made to provide clearance for the nose bridge.

I will need two adapters, one for the left and one for the right eye, which are mirror images of each other. The left adapter will have a "L" text and right a "R" text. These should be written with the `write` module, which should center the text.

I will require the `Write.scad` library for the text. Could you generate the necessary OpenSCAD files for this, please?

I'm looking to generate a highly customizable cogwheel model in OpenSCAD. I'd like the design to be more flexible than what I've seen online, specifically surpassing the capabilities of the one found at http://www.thingiverse.com/thing:525490/.

Essentially, I need a module that can create a cogwheel with the following adjustable parameters:

*   **Number of Teeth:** This should be a user-defined integer.
*   **Inner Radius:** The radius of the base circle before the teeth start; also a user-defined real number.
*   **Outer Radius:** The outer radius of the teeth tips; user-defined real number.
*   **Top Land Width:** The width of the flat part at the top of each tooth; real number.
*   **Space Width:** The width of the space between the teeth; real number.
*   **Depth:** The height or thickness of the cogwheel; real number.
*   **Cutout Radius:** The radius of a central hole or cutout; real number.

The cogwheel module should calculate the tooth thickness based on the other parameters. I envision a single module that takes all these parameters as input.

I'd like to be able to call this module multiple times, with different sets of parameters, to create different sized cogwheels. For example, I'd want to create a larger cogwheel with 30 teeth, and a smaller one with only 9 teeth, as well as changing the depth, inner, outer radii, and the other parameters.

Could you please generate an OpenSCAD file that allows me to do this? I don't have any preference for any specific libraries, but if you do use them, please list them explicitly.
