I need a parametric OpenSCAD design for a first layer print test, specifically for a delta printer. The test should consist of four circles arranged in a somewhat diamond pattern, plus some thin lines connecting them.

Here's how I'd like it to work:

*   **Overall Size:** I need to be able to define the overall size of the test print using a single parameter. This size will determine the bounding box for all the features. Let's call this parameter `size`.
*   **Circle Diameter:** I also need a parameter to control the diameter of the circles, let's call it `circle_diameter`. The circles should be centered.
*   **Circle Placement:** One circle should be at the origin (0,0), and the other three should be evenly spaced around it, forming a sort of diamond shape. The three off-center circles should be equidistant from the origin and the same distance from each other. The spacing should be calculated such that they are all within the bounds of the `size` parameter.
*   **Lines:** There should be thin lines connecting the origin to the other circles, also within the bounds of the `size` parameter.
*   **Thickness:** The circles and lines should all be a consistent, thin thickness. Let's use 0.3mm for the thickness.

I'd like to be able to easily customize both the overall size and the circle size using Customizer. I expect the design to be in a single `.scad` file.

Please let me know if you need any more information.

Hey, I'm looking for an OpenSCAD design for a modular pen holder, kind of like the one I saw on Thingiverse, but I'd like it to be fully parametric. I have a general idea, but I need help putting it all together.

Basically, I want to be able to specify:

*   The thickness of the material.
*   The height of the pen holder.
*   The diameter of each pen slot (they should all be the same for now).
*   The number of rows of pen slots.
*   Whether or not to include end rings at the beginning and end of the rows.
*   The angle of the opening cut out of each slot.

I'd also like the pens to sort of clip into place. The one I saw achieves this by having a cut-out in each slot with a small spherical extrusion that creates a little bump.

I want to be able to adjust that clip as well, so I'd want to specify:

* The cap angle for the cut-out used to make the clip, to adjust the shape.

I'd also like it to be modular so that I can easily change the number of rows and have them fit together nicely. It would probably work best by using a basic shape and a few modules, like you often see in OpenSCAD.

So, in summary, I need a parametric design where I can control material thickness, holder height, pen slot diameter, the number of rows, whether there are end rings, the opening angle for the slots, and the clip angle for the cutouts. It would be helpful to also have the ability to easily scale the height, kind of like in the provided example.

It looks like some existing modules like `minkowski()`, `rotate_extrude()`, and `linear_extrude()` could be useful.

I'm not sure if this would require one or two files, but whatever makes the most sense to you would be great.

I'm looking to generate some 3D models using a Brownian noise pattern. I've seen some implementations that look pretty interesting, where you get these kind of lumpy, organic looking shapes. The idea is that there's a grid of potential blocks, and Brownian noise determines the likelihood of a block existing at each grid location. So if one block exists at a certain point, there's a higher probability the surrounding points will also have blocks.

I'd like an OpenSCAD design that does this, but I want to be able to control several things:

*   The overall size of the generated cube area, expressed as `cubeSize`. This should determine the size of the overall 3D grid area within which the blocks can appear. For example, if `cubeSize` is 100, that means the total grid has a length, width, and height of 100 units.

*   The number of blocks along each edge of the grid area, which I'll call `blockNumber`. So if `blockNumber` is set to 20, there will be 20 block placement positions along each axis, meaning a 20x20x20 grid. This should be configurable.

*   The size of each individual block, which I'll call `blockSize`. This should control the physical dimensions of the block at each position. This should be distinct from cubeSize. If blockSize is 1, and blockNumber is 20, the total space will be 20 units across in each direction assuming no margin, but cubeSize could be larger.

*   A `seed` value to control the random noise pattern. This will let me generate different patterns and find ones I like.

*   A `density` value that can be used to control the overall density of the generated shapes. I want to be able to adjust it to add or remove blocks from the final shape. It could be thought of as a threshold value that the noise result is compared to.

I'm also hoping the implementation would use some of the more common libraries like `BOSL` or `BOSL2` if it's appropriate for the design of the blocks. Otherwise, you can rely on basic OpenSCAD primitives. I need the final design to output a single 3D polyhedron.

Hi, I need some help designing a set of parametric vacuum hose adapters. I'm using a shop vac and I need to connect different size hoses and tools. I'm working in metric and prefer mm.

Essentially, I need a tapered adapter that goes from one cylinder diameter to another. The user should be able to specify whether they are entering the *outside* diameter or *inside* diameter of both the large and small ends of the adapter. So for each end, the parameter should be like "LargeEndMeasured", which can be "outside" or "inside", and then the associated diameter like "LargeEndDiameter." Then the length of the large end, "LargeEndLength," similarly for the small end, "SmallEndDiameter", "SmallEndMeasured", and "SmallEndLength". Then I also need a "TaperLength" parameter for the length of the tapered section connecting the two ends.

I also need a parameter to control the wall thickness for the adapter, call that "WallThickness".  I want the code to calculate the inside diameter from the given outside diameter and wall thickness, and vice versa. I will need an optional internal lip at the end of the small diameter for situations where the tool is easily sucked into the adapter. A parameter called "InsideStop" with the options "yes" or "no" would be great for this. Finally, can there be a grip ring on the outside of the large end of the adapter? A parameter "LargeEndGripProjection" that controls the projection of the ring outwards would be great.  A zero value would mean no ring.

I'd like to keep the code simple and have no dependencies on external libraries if possible.

Could you help me generate the .scad file for this?

Hey, I'm looking to get some OpenSCAD code for a customizable rocket body segment. I've got some specific needs in mind, so let me walk you through them.

First off, the basic shape is a cylinder, but it needs to be parametric, so I can adjust the length, diameter, and skin thickness. These should all be in millimeters. I'd like to set the length of the section, the diameter of the section, and the thickness of the skin.

Next, I'd like to have the option for connectors and sockets on the ends, so I can stack these segments to make longer rockets. I need to be able to set the type of connector for the top and bottom of each section. The options are "connector," "socket," or "none" and they should probably be represented by a number like 1, 2, and 0, respectively. I'll need to be able to set these separately for the top and bottom of the cylinder.

Finally, I need internal bracing. I need to be able to specify the number of braces around the inner diameter of the tube, and these braces should run the length of the cylinder.

So, to recap, I need:

*   Parametric cylinder with:
    *   Adjustable length (mm)
    *   Adjustable diameter (mm)
    *   Adjustable skin thickness (mm)
*   Connectors/sockets at each end:
    *   Top connector type (connector, socket, or none)
    *   Bottom connector type (connector, socket, or none)
*   Adjustable number of internal braces that run the length of the cylinder

I'd like the code to be in multiple files, so it's easier to work with. I don't have any preferred file naming structure, so whatever makes sense to you is fine. I'd like to avoid using external libraries or modules if at all possible. Could you help me out?

I'd like to create a customizable 3D printable maze in the shape of a sphere. I've seen some examples that use a grid-based approach to generate the maze paths, and I'd like to do something similar.

Here's what I'm envisioning:

The maze itself should be formed by walls on the surface of a sphere. The sphere should be divided into a grid of "blocks" both vertically and horizontally. I should be able to control the number of blocks in each direction.  The walls will separate those blocks. I'd like the maze generation to be done via an algorithm, not just manual placement of walls. I am envisioning a recursive backtracker.

I need to control the following parameters:

*   **`radius`**: The radius of the sphere.
*   **`vertical_blocks`**: The number of grid blocks vertically.
*   **`horizontal_blocks`**: The number of grid blocks horizontally (around the sphere).
*   **`wall_height`**: The height of the maze walls.
*   **`wall_thickness`**: The thickness of the maze walls.
*   **`arm_and_base`**: A boolean flag (or maybe a "yes"/"no" string) that determines whether or not to generate a support structure for the sphere. If this is true (or "yes"), then a base and a small arm structure should be generated to help the sphere stand up. I envision this as a cylinder going through the center of the sphere, another cylinder for a base at the bottom, and some arching support structures going from the cylinder to the surface of the sphere.
*   **`simple_support_on_the_top`**: A boolean flag (or string) to generate small removable support blocks at the top of the sphere, if `arm_and_base` is also set.

The maze should be generated using a random algorithm - the recursive backtracker mentioned above is a good place to start - and should be different every time the design is compiled, at least as a default.

Could you provide me with the necessary OpenSCAD code to achieve this? I don't need any external libraries. All of the functions and modules should be defined within a single .scad file.

Hey, I'm looking to create a vase-like shape with a kind of twisted, flared design using OpenSCAD. I have a basic idea in mind, but I'd like it to be parametric so I can easily tweak the shape.

The vase should be built up in sections. It starts with a base, then a series of cylindrical body sections that twist and flare outwards. Each body section is connected by a short rim section. I want the cross-section of each body and rim section to be the same base shape, just scaled and rotated appropriately.

The base shape is a circle with four smaller circles "stuck" to it, one in each quadrant. Each of these should be offset slightly inward from the main circle, controlled by a "stickout" parameter, and I'd like to be able to control the number of sides of all of the circles making the shape. The base shape has to be able to have a thickness parameter so I can make it either solid or hollow.

I'd like to control the radius of the base shape, the number of sides in the circle, the thickness of the shape, the height of each of the body sections, and the amount of twist and flare applied to each section as it goes up.

The flare should be cumulative, so each body section should be more flared than the last. The twist should alternate direction and can be a single angle rather than cumulative.

Each rim should be a small linear extrusion connecting body sections. It should scale along with the body sections, and I want a single base height that controls the height of all rims and base.

The cross sections for all extruded sections (body, rim, and base) should be the same - that is, the described base shape.

I don't need any additional libraries included, just a single .scad file with all the modules defined within it. The design seems to look best when the polygon sides is an even number.

Hey, I'm looking to get an OpenSCAD design for a manhole cover and its base, kind of like a desk toy. I have some specific ideas for the cover itself, and I'd like it to be parametric.

The manhole cover should be a cylinder with a few main features. I want four "feet" equally spaced around the circumference to act as supports, kind of like tabs. The top surface should have a recessed pattern - I'm thinking concentric rings that have a small groove cut in them. Finally, I'd like to be able to add some text to the top of the cover, and I want it to extrude _downward_ into the cover.

For the base, I'd like it to be a bit like a wide, flat cylinder with an indented top so the cover can sit nicely inside. I want the base to have supports like the manhole cover, but I want them to be larger and more like wedges than tabs, and angled. The wedges should not be flush to the base but they should extrude a small amount. I'd like the feet on the manhole cover to fit loosely on top of these wedges.

I need these to be parametric, so I can change the diameter, thickness, text, etc. I'm open to your ideas though! Let me know what you think.

Hey, I'm looking to design a bracket for my Makeblock ultrasonic sensor that will allow me to mount it to a servo. I've got the basic dimensions for the sensor and servo, but I'd like to make it parametric so I can tweak things easily.

Essentially, I need a faceplate that holds the sensor, a middle section that connects to the servo bracket, and the servo bracket itself. The faceplate will have two holes for the "eyes" of the sensor, and the bracket will need to accommodate the Makeblock servo.

Here's a breakdown of the dimensions and how they should relate to each other. This might be a bit much, but I'm not sure how else to be clear:

**Faceplate:**
*   **faceWidth:**  The width of the front panel. I'm currently using 34.
*   **faceHeight:** The height of the front panel, currently 20.
*   **faceDepth:** The thickness of the front panel, currently 3.

**Ultrasonic Sensor "Eyes":**
*   **eyeDiameter:** The diameter of the sensor eyes, 17.1.
*   **eyeCentersDistance:** The distance between the center of the eyes, 32.25.
*   **eyeBoardThickness:** The thickness of the sensor's circuit board, 2.

**Middle Connection Piece:**
*   **middleHeight:** The height from the bottom of the faceplate to the bottom of the bracket, I think this needs to be at least 24.
*   **middleBottomPercentage:**  This is the proportion of the middle connector that joins to the lower bracket (as a percentage). I need to be able to control how far the middle of the connector juts in. I'm starting with 0.75.

**Servo Bracket:**
*   **servoDepth:** The depth of the servo, 13.
*   **servoWidth:** The width of the space between the side brackets, 23.1.
*   **bracketHeight:** The height/thickness of the side brackets, 3.
*   **bracketWidth:** The width of the side brackets, 5.
*   **screwDiameter:** The diameter of the screw holes on the servo mount, 2.0.

**Hidden Internal Dimension (Needed to properly place the servo mounting block):**
*  **servoTopHeight:** the height of the servo mounting block, 15

Basically, the faceplate holds the ultrasonic sensor, the middle piece connects the faceplate to the bracket, and the bracket is what attaches to the servo. The center of the sensor eyes should be flush with the front of the faceplate and protrude into the back.  The servo bracket should have screw holes to mount to the servo.

I’d like to keep the design parametric, so I can easily adjust the dimensions if needed. It should also be easy to print. I'm also not very good at coding, so I need the SCAD code to be organized and easy to read. I'd prefer to avoid using any extra libraries if possible. Could you create the OpenSCAD code for this?

Alright, I'm looking to design a modular shelf system for storing empty glass jars, like the ones that pickles come in. I have a few key ideas in mind.

First, the system should be made up of individual modules that can be connected together. Each module will hold a single jar upside down, so the open end (the former bottom) faces outwards and the cap is hidden. The modules should have a slightly tilted cutout for the jar, so that the jar doesn't fall out easily, and will also slide back into place if the shelf is moved.

I need the modules to be parametric, so I can adjust the size to fit different jars. I was thinking I should be able to set the module's width, depth, height, the diameter of the jar opening, and the tilt angle of the jar cutout. I'd also like to define the wall thickness for the module.

The connection between modules should be done with separate connectors. This makes it easier to adjust the connector's fit without reprinting the whole module. The connector should slot into the sides of the module. I need a parameter for the keyslot size/shape so that they fit snuggly into each other. It would also be nice to have a parameter for a "fit gap" which allows the connector to be adjusted for a particular printer. I would like it to be able to have an inset and a dent inset.

For each module, I need a few more specific features.  The bottom edges should have a small chamfer or "fase". Also, there should be a "tube" around the glass opening, with adjustable depth and diameter, which is angled slightly. Finally, I'd like a snapping mechanism for each module, which has adjustable height.

I'd like to control what gets generated. Something like "parts" as a parameter, that lets me select to generate just the module, just the connector, or both. I'm not sure about other parameters at this time.

For libraries, I think this would work best with OpenSCAD's built in functions. No need to worry about MCAD or BOSL or anything like that.

I think that's it for the basic idea. Please let me know if anything is unclear.

I'm looking to design a new bracket for mounting an ultrasonic sensor and servo, similar to the design I'm currently using, but with a few modifications and some parameters. Currently, I'm using a bracket I found online (and I have the .scad code for it) which works, but is a bit inflexible. I'd like to be able to more easily adjust things like the bracket length, width, servo hole placement, and the servo brace dimensions.

Essentially, I need a bracket with:

*   A main body with rounded corners, with adjustable length, width and corner radius.
*   Holes for mounting screws, at locations that can be specified. It would also be helpful to be able to specify the diameter of these holes.
*   A central hole for mounting a servo, with a diameter and X offset from the edge of the bracket that is also adjustable.
*   Servo braces (or "stoppers") on either side of the servo hole, that are also adjustable in length, width and offset from the center of the hole.

The current bracket's design uses these parameters:
 *   `bracketHeight = 3;` (I would like this to be adjustable too)
 *   `servoBraceSpace = 5.2;`
 *  `servoHoleDiameter = 7.3;`
 * `servoHoleXLoc = 40;`
* `bracketLength = 51;`
*  `bracketWidth = 24;`
 *`servoBraceLength = 15;`
*`servoBraceWidth = 5;`

I need a parametric OpenSCAD design for this. It would also be good if it uses the `rounded_square` module from the BOSL2 library for generating the rounded rectangle with corners. It doesn't need to have the `rotate([180,0,0])`, so I don't expect the design to be inverted by default.

I want the main bracket to have screw holes for mounting to another piece. I'm thinking three screw holes would be sufficient and it would be ideal to be able to adjust the x and y location of these holes along with the diameter.

It's important to me that I can easily adjust all these dimensions with parameters. Could you create that design for me?

I need a parametric OpenSCAD design for an angled ruler. I'm looking to cut angled corners on woodworking projects, so it needs to be fairly precise.

Here's a breakdown of what I'm envisioning:

*   **Angled Ruler Portion:** This is the main part that creates the angled edge, with the angle as a parameter. So I'd need a `degree` variable, which I can set between, say, 15 and 80 degrees. The width of this ruler section should also be adjustable, a `width` parameter for the ruler itself.

*   **Alignment Base:** I want a flat base section, perpendicular to the angled part, that allows me to align the ruler easily against the edge of my workpiece. This needs a `base_length` parameter. It should have the same width as the angled ruler portion.

*   **Connector:** The base and angled ruler should be connected by a rectangular connector. Its length would be `connector_length`, and its width should also be adjustable with a `connector_width` parameter.

*   **Thickness:** The entire ruler should be extrude to some thickness, with a `thickness` variable.

*   **Notch:** Include a small notch on the angled edge of the ruler. This helps with alignment and makes printing easier by avoiding extremely thin sections. Make its length a variable: `ruler_notch`

*   **Text:** I also want the option to display the degree angle on the ruler itself. I'd like a toggle `show_text` to turn it on or off (1 or 0). If enabled, make the text an adjustable `text_thickness` thicker than the base thickness of the ruler. It should be positioned centered on the base and be sized relative to `base_length`, and display the value of the `degree` variable using the degree symbol ("°").

So, to summarize the parameters:

*   `degree` (angle in degrees, 15-80)
*   `width` (width of the ruler)
*   `connector_length` (length of the connector)
*   `thickness` (thickness of the ruler)
*   `show_text` (1 to show text, 0 to hide text)
*   `text_thickness` (thickness of the text)
*   `base_length` (length of the base)
*   `connector_width` (width of the connector)
*   `ruler_notch` (length of the notch on the angled ruler)

I don't think I need any special libraries for this. Can you generate the OpenSCAD code for this?

[Assistant]
ruler.scad:
```
// Degree of the ruler
degree=45; //[15:80]

// Width of the ruler
width=50;

// Length of the connector between alignment base and angled ruler
connector_length=30;

// Thickness of the ruler.
thickness=1;

/* [Text] */

// Do you want to add degree as text to the ruler
show_text = 1; //[1:Yes,0:No]

// Thinckness of the text
text_thickness = 1;

/* [Advanced] */

// Length of the base that helps with alignment.
base_length = 15;

// Width of the base to angled ruler connector
connector_width = 10;

// Notch on the side of the ruler. Helps to maintain ruler alignment. Additionally, it helps while printing as extremely thin parts do not print good enough.
ruler_notch = 5;

    [0,0],
    [width,0],

    [0,ruler_notch+tan(degree)*width]

cube([connector_width,connector_length,thickness]);

//Base
cube([width,base_length,thickness]);

//Text
if(show_text) {
    translate([width/2, base_length/3/2, 0])
    linear_extrude(thickness+text_thickness)
    scale([base_length/15, base_length/15, 1])
    text(str(degree, "°"), halign="center");

Hi, I'm looking to get an OpenSCAD design for a parametric tripod. I've seen a design I quite like, and I'll describe that, but I want to make sure I can customize it.

The tripod has a central cylindrical base and three legs that attach to it. The base itself should also be a cylinder. The legs are attached to the base by angled plugs, and the legs themselves are essentially elongated, slightly thickened, cuboids. It's important that the legs attach to the base with an angled plug and that the legs themselves are hollow, so they can be printed with little infill.

Here's the breakdown of parameters I'd like to control:

*   **Base:**
    *   `BaseRadius`: The radius of the main cylindrical base.
    *   `BaseHeight`: The height of the main cylindrical base.

*   **Legs:**
    *   `LegWidth`: The width of the leg.
    *   `LegThickness`: The thickness of the leg (this should be the smaller dimension).
    *   `LegHeight`: The length of the leg.
    *   `LegPlugThickness`: The thickness of the plug attaching the leg to the base.
    *   `LegAngle`: The angle of the leg with respect to the base.
    *   `LegOffset`: A parameter to shift the position of the leg slightly, especially important if I'm playing with XY compensation later. This should affect where the leg attaches to the plug, in the direction of the leg axis.
    * `LegPlugXYCompensation`: A parameter to modify the leg itself, essentially adding a bit of extra width and thickness to the legs, and affecting how they fit into the plug.

*   **Center Holder:**
    *  `HolderRadius`: The radius of the central hole.
    *  `HolderType`: An option to choose the hole's shape, either `"Circle"` or `"Hexagon"`.

*   **Display:**
     * `DrawType`: The ability to display only specific parts, ` "Head"`, `"Legs"`, `"All"`, or `"Demo"`, for testing and inspection. This "Demo" should also flip the `Head` component upside-down.

Also, please try and make the design as close as possible to the example I will paste here, which was also made in OpenSCAD, with similar structuring.

```
BaseRadius = 30;
BaseHeight = 4;
LegWidth = 10;

I'm looking to get an OpenSCAD design for a wire clip that mounts to the side of a table. I want to be able to customize a few things, like how many wires it can hold, the table thickness, the wire size, how far the bracket extends, the wire clearance, and the bracket thickness.

For the wire clip itself, I'd like to be able to adjust how flat it is (using a scale factor), the roundness of the fillets, the angle of the clamp to make the wires grip better, and optionally, the extrusion amount if I don't want it to just be the same as the bracket thickness. I'd like to be able to set a custom extrusion amount or use bracket thickness if that is zero.

I'd like to have the bracket extend under and over the table edge. Also, the wire clearance should be less than the wire thickness to make the wire snap in. The wire clips should also be positioned vertically to keep wires neatly tucked away. The bracket should use fillets on the inside and outside of the corner to give the design a smoother more durable look.

I don't really know much about code so I am not going to attach any libraries.

Hey there! I'm trying to design a parametric flying wing, and I've got some specific ideas about how it should be constructed. I'd love some help generating the OpenSCAD code.

The design will have a central wing section, and then the wing on either side of that central section. I'd like the code to allow me to control a few key parameters:

*   **Wing Length:** Obviously, the overall length of the wing (from root to tip).
*   **Wing Angle:** I want to be able to change the angle at which the wing sweeps back from the root.
*   **Visibility Spread:** This determines how far apart the two mirrored wing sections are from each other on the z axis. Basically, this will change the visibility of each mirrored wing.
*   **Chord:** The chord of the wing profile should be adjustable. This is essentially the length of the wing at its cross-section.
*   **Airfoil:** I want to use a NACA airfoil. The code should include the full definition for this. I think the specific profile should be adjustable (NACA 4-digit series, though just letting me tweak the digits would be fine). I should also be able to change the number of segments that make up the airfoil curve.
*   **Bulkheads:** The design should use bulkheads to define the shape of the wing. The bulkheads should be spaced along the length of the wing and should also have adjustable parameters like their thickness. It should also be possible to make a series of bulkheads with different chord lengths and offsets to change the shape of the wing.
*  **Wing Sections**:The wing should be constructed of wing sections that build up to the overall wing shape. I should have control over the length, scale, and sweep of each section.

I’m also envisioning some design features like:
    *   A way to create internal sockets within the wing for structural integrity
    *   The ability to add holes to the bulkheads for weight savings, while still allowing them to maintain their shape.

I'd like the main function to be a module called `wing_pair`, that creates two mirror wings that are controlled by a visibility spread. Then it would call the `wings` module, which creates a single wing, and then the `wings` function would call `wing` which defines the actual shape of the wing. Then that `wing` function calls the `wing_part` module, which builds the various sections of the wing that make up the overall shape, which then builds using the `wing_section` module. The `wing_section` module builds the shape with the `skin` and `bulkhead` modules, then the `skin` and `bulkhead` modules use the `airfoil_outline` function to create the airfoil shape, which uses the `airfoil` function and the `airfoil_data` function. I think I've pretty much covered what the code should do.

I'm not worried about any specific libraries; I'd like to just generate all of the code. Let me know if you have any questions. Thanks!

I'm trying to create a 3D printable object that looks like different words from different viewing angles. I saw this really cool concept based on the Raetz "Yes No" sculpture and the Mojoptix sundial, and I want to try making something similar.

The basic idea is to take two words, extrude them, rotate one, and then take the intersection. The intersection will then form the 3D object. I'd like to be able to customize several things:

1.  **The two words:** Obviously, I need to be able to specify what text is shown.
2.  **The rotation angle:** I want to be able to control the angle between the two extruded texts, like the example uses 90 degrees.
3. **Font selection:** I'd like to be able to choose which font to use for both texts and ideally style parameters like bold or italic. I know not all fonts will work well, but I'd like to experiment.
4. **Base:** I need a base to print the text on, so there would be a flat extrusion for the base, using a hull and projection of the letters. I want to be able to control the thickness of the base.

Also, I need to consider that some letters work way better than others for this method. Letters with overhangs like F, P, S, T, Z and lowercase letters tend to be very difficult to print without support. I should probably stick to simple, all-caps letters without disconnected parts like 'AHIKLMNVWXY' or maybe some of 'BDJOQRU'.

I'd prefer to get an OpenSCAD file, or maybe a couple of files if it makes the design easier to manage, that would let me customize all of these parameters. I know there might be issues with certain fonts, so I’m prepared to use a simple font to test before trying more complicated ones. Also, could you please use the BOSL2 library? I've used it before, and I like how it works.

text2 = "MIA";

text_font = "DejaVu Sans:style=Bold";
offset_angle = 90; // [0:90]
base_thickness = 1;

module letters() {
     rotate([90, 0, 0])
     render(convexity=10)
     intersection() {
	  translate([0, 0, -500]) linear_extrude(1000) text(text1, font=text_font);
	  rotate([0, offset_angle, 0]) translate([0, 0, -500]) linear_extrude(1000) text(text2, font=text_font);
     }
}

module base() {
     translate([0, 0, -base_thickness + 0.1]) linear_extrude(base_thickness) hull() projection() letters();
}

union() {
     base();
     letters();

Hi! I'd like to get a parametric OpenSCAD design for a radiator bleed key, something that I can easily adjust for different sizes. I have a rough idea of the shape, and I'd like to make sure all the dimensions are configurable.

The basic design has a cylindrical base with a spherical end. Then, it has a handle offset from the base, attached by a connecting piece, kind of like a "T" shape rotated. The handle itself will be made of rounded parts. Finally, there's a square hole through the cylindrical base.

Here are the parameters I think I need:

*   **Cylinder Base:**
    *   `cylinderHeight`: Height of the cylinder.
    *   `cylinderRadius`: Radius of the cylinder.
*   **Spherical End:**
    *   The sphere should have the same radius as the cylinder.
*   **Square Hole:**
    *  `holeSize`: The size of the sides of the square hole, it should cut through the base cylinder.
    *  `holeOffset`: How far up the base the hole should be located.
*   **Handle:**
    *   `handleDepth`: The depth/thickness of the handle.
    *   `handleWidth`: The width of the handle.
    *   `handleHeight`: The length of the handle, before the rounded parts.
    *   `handleRadius`: The radius of the rounded parts of the handle.
    *   `handleOffset`: How far from the cylinder top the handle will sit.
    *   `handleHoleRadius`: The radius of a hole I will need on the handle.

I'm assuming that the handle offset will be relative to the top of the cylindrical base and the handle's rounded parts are actually short cylinders. It would be great to have the handle connect to the base with a solid connection.

Also, I'd like the design to have a `fragments` parameter that I can use to control the smoothness of the curves.

I'm hoping you can provide me with an OpenSCAD file or files using these parameters.
