I'd like to design a door nameplate with some customizable features. It should have a rectangular base, and I want to be able to add text to it. The text should be able to be either embossed (sticking out) or engraved (cut in). I'd like to control the font, the text itself, the text's height, and the spacing between the letters.

For the base of the nameplate, can you just make it a simple rectangular shape for now? I'm not too concerned about the dimensions for now, but I do want the option to control its overall size later, ideally using a scale factor.

I'd like the ability to pick from some pre-defined font options, like "Knewave", "Letters", "Orbitron", "BlackRose", and "Braille", using the corresponding .dxf files.

I want to be able to use the "write" module from the `Write.scad` library to render the text.

Could you also please include the option to turn the text on or off, as there may be cases where I don't need any text at all?

Also, if you could color the text salmon, that would be great.

Hey, I'm looking to design a customizable arm for a robot I'm building, and I've got some pretty specific ideas about how I'd like it to work. I want to be able to adjust different aspects like the overall shape (either straight or curved), the length, and the size of the shoulder and hand. Also, the joint connecting the arm to the body needs to be configurable as either a male or female connector, with adjustable diameter and height.

I'd also like the hands to have variable types. In the existing code I'm using, they are described by a 'Tipo_Mano' variable and I'd like to maintain that behavior, so if the type is equal to 1, the hand should be of the same type, and so on.

The existing design uses some functions that limit the minimum and maximum values for parameters, which I'd like to maintain.

Can you write an OpenSCAD file that can generate this? I'm okay if it's multiple files as well. I'd also like to avoid having to deal with any external libraries or anything complicated like that.

I need to design a ring support for a chemistry lab, and I'd like a parametric OpenSCAD design. I've got a basic idea already.

The ring itself should be a hollow cylinder. I want to be able to control the outer radius, inner radius, and height of the ring. There should also be a rectangular bar connected to the side of the ring, extending outwards. The bar's length should be adjustable, and it should be the same height as the ring. The width of the bar should also match the ring's height. I need to be able to specify all those dimensions as parameters.

Can you provide a parametric OpenSCAD file that will allow me to generate this ring support? I don't have any particular preference for libraries, but any standard approach is great.

[Assistant]
simple_ring_support.scad:
```
//Outer radius of ring
o=25;
// inner radius of ring
i=20;
//height of ring
h=6;
//length of bar
l=100;

//ring
difference(){
cylinder(h=h,r=o, center=true, $fn=100);
cylinder(h=h+1,r=i, center=true, $fn=100);
}

//bar
translate([i+(o-i)/2,-h/2,-h/2])cube([l,h,h]);

I need to design a bracket to hold two aquarium heaters in the bottom of my sump. The suction cups that came with the heaters are useless and I want something more reliable. I'm envisioning a base with four posts that will hold the heaters in place. I'd like this to be easily customizable, mostly for different heater diameters.

Here are the details:

*   **Base:**
    *   The base should be a rectangular shape.
    *   I'd like to adjust the base width, length, and thickness.
    *   I'd like some rectangular cutouts on the base to allow water to flow through, and to save on plastic.
    *   I want some rounded fillets on the corners of the base for nicer look and better print quality.
    * I want to be able to set the number of cutouts along the base.
*   **Posts:**
    *   There should be four posts, two for each heater. The posts will be set up in pairs, with each pair meant to hold one heater.
    *   The posts will have a base and a ring to hold the heater, with a gap between the ring and the base of the post.
    *   The posts will have a rectangular base, and the ring will be a cylinder with a hole in the middle to fit the heater.
    *   I need to be able to set the heater diameter, the height of the center of the heater, and the distance between the center of the heaters.
    *   The post width and length should be calculated based on the heater diameter, and have a separate value for the ring.
*   **Customization:**
    *   I'd like to be able to adjust the base width, base length, base thickness.
    *   I'd like to be able to adjust the heater diameter, post height, post spacing (distance between the *centers* of the posts for each heater).
    *   I'd like a variable to control the number of holes in the base, and the spacing between them.

I'm hoping for a parametric design in OpenSCAD. Could you create the necessary .scad file or files to achieve this? I don't expect any custom libraries to be required.

Hey, I'm trying to make a customizable mug that screws onto different types of jars, like those used for canning or 2-liter bottles. I've got some basic dimensions and ideas, but I need help creating a parametric OpenSCAD design.

Here's what I'm thinking:

*   **Jar Compatibility:** I want to be able to easily switch between different jar types. I've already got measurements for 2-liter bottles and standard narrow/wide-mouth canning jars. I'm going to want an option for "Custom" jars as well.
*   **Parametric Design:** Everything should be customizable through parameters – jar size (both pre-defined and custom), rim thickness, handle length, handle thickness, and the space between the handle and the jar rim.
*   **Threads:** The mug needs screw-on threads that fit the selected jar properly. I need to be able to control thread height, depth, and angle.
*   **Modular Design:** It'd be great if the design was broken down into modules like 'bottleNeck', 'bottleHolder', 'bottleCap', 'bottleMug', and 'funnel' so it is easy to make new parts, or edit specific pieces.
*   **Output Options:** I want the ability to output just the thread geometry (for testing fit) or the full mug with handle, or even a funnel attachment (all as separate options).

Here are my base measurements for the jars:

*   **2-Liter Bottle:**
    *   Inner diameter (bottleID): 25.07mm
    *   Outer diameter (bottleOD): 27.4mm
    *   Thread vertical spacing (bottlePitch): 2.7mm
    *   Angle of thread screws (bottleAngle): 2 degrees
    *   Length of thread (threadLen): 15mm
    *   Height of rim around jar (bottleHeight): 9mm
*   **Narrow Canning Jar:**
    *   Inner diameter (bottleID): 70mm
    *   Outer diameter (bottleOD): 71.5mm
    *   Thread vertical spacing (bottlePitch): 5mm
    *   Angle of thread screws (bottleAngle): 2 degrees
    *   Length of thread (threadLen): 15mm
    *   Height of rim around jar (bottleHeight): 12mm
*    **Wide Canning Jar:**
    *   Inner diameter (bottleID): 86mm
    *   Outer diameter (bottleOD): 86.06mm
    *    Thread vertical spacing (bottlePitch): 5mm
    *   Angle of thread screws (bottleAngle): 2 degrees
    *   Length of thread (threadLen): 25mm
    *   Height of rim around jar (bottleHeight): 12mm

For the **Custom Jar** option, I'd need parameters for:

*   `jarID` (inner diameter)
*   `jarOD` (outer diameter)
*   `jarPitch` (thread vertical spacing)
*   `jarAngle` (angle of threads)
*   `jarThreadLen` (length of thread)
*   `rimHeight` (height of rim around jar)

And here are the other parameters for the mug itself:

*   `rim`: Thickness of the rim (e.g. 5mm)
*   `handleLength`: Length of the handle (e.g. 75mm)
*   `handleThick`: Thickness of the handle (e.g. 20mm)
*  `handSpace`: Space between the jar rim and handle (e.g. 25mm)

The `part` variable would select which part of the mug to render and the `clearance` variable would adjust the fit. These should be editable as well.

I want to generate the threads using the `linear_extrude` function for the thread geometry.

I think I've covered everything. Could you generate the necessary OpenSCAD code for this? I'd like it to be as flexible and easy to use as possible. I'm not using any libraries yet, but if it makes sense to use a particular library I'm open to that.

Hey, I'm looking to get some custom mouthpiece designs generated, specifically for brass instruments, and I'm hoping you can help me out. I've played around with some OpenSCAD code before, and I kind of like the way the design is approached, so I'm hoping you can create a parametric set of files for me. I've got a basic design I've been playing with, and I can use that as a starting point.

The core of the design involves a rotationally extruded shape defining the cup, throat, and backbore of the mouthpiece. I want to be able to control the overall dimensions and shapes through parameters. This is the basic idea:
```
// (c) 2012 Wouter Robers

// [Trumpet:16, Trombone:21] Larger Cup Diameters are optimized for lower ranges, giving a richer tone. Smaller diameters assist high range playing.
CupDiameter=32;

// [Trumpet:8, Trombone:16] Shallower cups greatly assist playing in high ranges but do so at the cost of fullness of tone. Deeper cups assist low range flexibility and rich tone.
CupDepth=30;

// [0 (Conical) - 1 (Spherical)] Spherical cups have brighter, more projected tones, while conical cups have less tone definition.
CupSphereFactor=0.4;

// [Trumpet:6 Trombone:8] Wider rim widths reduce the pressure on the lips, allowing greater stamina. It does, however, reduce flexibility.
RimWidth=6;

// [0 (flat) - 1(round)] Sharper rims reduce stamina but increase control.
RimShape=0.9;
RimRadius=RimShape*RimWidth/2;

// A sharper throat contour gives a more harsh, projected tone and a rounded contour gives a deeper, richer tone, but less definition.
ThroatRadius=3.5;

// [Trumpet:4, Trombone:5] Larger throat diameters give more volume but less control.
ThroatDiameter=10;

// Diameter of the pipe that fits into your instrument. [Trumpet:9.5, Trombone:12]
BackPipeDiameter=13.5;
FrontPipeDiameter=BackPipeDiameter+2;
BoreDiameter=BackPipeDiameter-1.7;

// Total length of the mouthpiece [All mouthpieces usually 88]
MouthPieceLength=88;

//Height of the "foot" that binds the mouthpiece to the platform. Set to 0 for no foot.
PrintingFootHeight=1;

MakeMouthPiece();

module MakeMouthPiece(){

$fs=1; // set minimum polygonsize
$fa=8; // set minimum circle angle

// ======================

//Making the cup shape

CupBottom=[ThroatDiameter/2+ThroatRadius*(0.17+CupSphereFactor*0.3),CupDepth+ThroatRadius*(0.43-CupSphereFactor*0.3)];
CupTop=[CupDiameter/2+RimRadius*0.02,RimRadius-RimRadius*.2];

Cup45Deg=(0.5+CupSphereFactor*.15);
Cup30Deg=(0.25+CupSphereFactor*.1);
Cup60Deg=(0.75+CupSphereFactor*.1);

CupshapePoint1=[Cup30Deg*CupTop[0]+Cup60Deg*CupBottom[0],Cup30Deg*CupTop[1]+Cup60Deg*CupBottom[1]];

CupshapePoint2=[Cup45Deg*CupTop[0]+Cup45Deg*CupBottom[0],Cup45Deg*CupTop[1]+Cup45Deg*CupBottom[1]];

CupshapePoint3=[Cup60Deg*CupTop[0]+Cup30Deg*CupBottom[0],Cup60Deg*CupTop[1]+Cup30Deg*CupBottom[1]];

// Putting the moutpiece on the platform

]);

//Rim rouding
translate([CupDiameter/2+RimRadius,RimRadius, 0])circle(RimRadius);

//Rim rouding
translate([CupDiameter/2+RimWidth-RimRadius,RimRadius, 0])circle(RimRadius);

//Throat rouding
translate([ThroatDiameter/2+ThroatRadius,CupDepth+ThroatRadius,0])circle(ThroatRadius);

//Printing base
translate([BoreDiameter/2,MouthPieceLength,0]) square([10,PrintingFootHeight]);

}

//decorative rims on the outside
translate([FrontPipeDiameter/1.35,CupDepth+RimWidth*2.5, 0])circle(RimRadius*1.45);
translate([FrontPipeDiameter/1.45,CupDepth+RimWidth*3, 0])circle(RimRadius*1.2);
translate([FrontPipeDiameter/1.55,CupDepth+RimWidth*3.5, 0])circle(RimRadius*1.0);
}
}
```
I'd like a design that lets me control:

*   `CupDiameter`: The diameter of the cup opening.
*   `CupDepth`: The depth of the cup.
*  `CupSphereFactor`: A factor that influences the shape of the cup, ranging from conical to spherical.
*   `RimWidth`: The width of the rim.
*   `RimShape`: How rounded the rim is, ranging from flat to round. This determines a `RimRadius`.
*   `ThroatRadius`: The radius of the throat rounding.
*   `ThroatDiameter`: The diameter of the throat.
*   `BackPipeDiameter`: The diameter of the backpipe.
*  `FrontPipeDiameter`: The diameter of the front pipe, derived from the BackPipeDiameter.
* `BoreDiameter`: The bore diameter, related to the BackPipeDiameter.
*   `MouthPieceLength`: The total length of the mouthpiece.
*   `PrintingFootHeight`: The height of the base for printing.

I'd like to keep the same kind of approach to generating the overall curve, using the `CupSphereFactor` and some calculated points to define a smoother contour in the cup area. You can see how the `CupTop`, `CupBottom`, `CupshapePoint1`, `CupshapePoint2`, and `CupshapePoint3` are derived.

Also, I'd prefer to have separate files for the main mouthpiece shape and for some additional decorative elements that are just circles extruded around the main form, if that's not too much trouble. The main file should generate the main form using the rotation extrusion and related subtractions, along with the print foot, but omit the decorative rings.  I think using the same variables in both files would be best.

Finally, I think I'd like the code to be self-contained if possible, rather than relying on any particular external libraries. I'm not sure if that is too much to ask, though.

Hey there! I'm looking to create a customizable name tag with integrated clips for my filament shelf. I've seen some good examples on Thingiverse, specifically a customizable name tag (thing:74621) and a customizable round clip (thing:65816), and I want to combine those ideas for my filament shelf (thing:339020).

Essentially, I need an OpenSCAD design that lets me specify the text on the tag, along with its size and depth, as well as the overall size of the tag itself. Then I want to be able to add a specified number of round clips to the back of the tag. These clips should also have their size and opening angle customizable.

I'd like to be able to control the following parameters:

*   **Text:** The text string for the tag.
*   **Text Height:** The height of the text.
*   **Text Depth:** The extrusion depth of the text.
*  **Font**: The font of the text, specifically I'd like to use any font readable by the 'write' function from the 'Write.scad' library.
*   **Plate Width:** The width of the rectangular tag.
*   **Plate Height:** The height of the rectangular tag.
*   **Plate Thickness:** The thickness of the tag.
*    **Plate Border**: The border thickness of the tag.
*   **Clip Number:** The number of clips on the back of the tag.
*   **Clip Spacing:** The distance between the centers of the clips.
*   **Clip Inner Diameter:** The inner diameter of the clip.
*   **Clip Width:** The width/height of the clip.
*   **Clip Wall Thickness:** The thickness of the clip walls.
*   **Clip Opening Angle:** The angle of the opening in the clip.

I also want to be able to choose whether I want to output just the nameplate with the text, or the nameplate with the clips. I think this means I'd need a parameter for outputting the "back" or "text" of the design.

Finally, I'd like to have the option to add a foot (angled support) to the back instead of the clips, or maybe a pin. I'm thinking this would require parameters for:

*   **Backing**: a selection between "none", "foot", "pin", or "clip".
*   **Foot Angle:** The angle of the support foot relative to the back of the tag.
*   **Pin Length:** The length of the pin
*   **Pin Diameter:** The diameter of the pin.

I think that about covers it! I'm comfortable using the 'write/Write.scad' library, so don't worry about needing to re-implement that function.

I'm looking to design a delta printer effector and carriage (or lift) system that uses magnetic joints. I've got some specific ideas about how I want it to work, and I'd like to create a parametric OpenSCAD model to make it easy to adjust and build.

Here's the general idea:

*   **Magnetic Joints:** The system should use ring magnets embedded in the effector and carriage, with bearing balls attached to the rods. The magnets will attract the bearing balls to create the joint.
*   **Parametric Design:** I need to be able to adjust the following parameters:
    *   **Ball Diameter:**  The diameter of the bearing balls in mm.
    *   **Magnet Outer Diameter:** The outer diameter of the ring magnets in mm.
    *   **Magnet Inner Diameter:** The inner diameter of the ring magnets in mm (the circle where the ball will touch).
    *   **Magnet Height:** The height of the ring magnets in mm.
    *   **Joint Distance:** The distance between the two magnetic joints in the X direction, when viewed looking down on the effector or carriage.
    *   **Joint Rest Angle:** The resting angle of the joints relative to the horizontal plane. So that the ball is attracted to a canted magnet and the joints themselves have some inherent angle when they aren't in tension.
    *   **Joint Offset Center (Effector):** How far the joint pair is offset from the center of the effector in the Y direction.
    *   **Joint Offset Center (Lift):**  How far the joint pair is offset from the center of the lift in the Y direction.
*   **Effector:**
    *   The effector should have three sets of magnetic joints arranged at 120-degree intervals around the center.
    *   It needs a customizable nozzle mount. I'm thinking something where I could define a nozzle radius and the mount is constructed using a conical drill pattern. Include mounting holes for attachment and cable routing.
*   **Carriage/Lift:**
    *   The carriage should have two sets of magnetic joints, in mirrored arrangement.
    *   It needs a user-defined mounting plate that I can customize. The mounting plate is mostly to illustrate mounting to a linear rail or similar.
*   **Visuals:**
    *   It would be great to have options to toggle the display of the bearing balls and magnets for visual clarity.
*   **Modules:** Break the design down into useful modules to make the code easier to follow.

I've seen some examples using the `hull()` function, but I'm not married to any particular approach. I'm not using any specific libraries like MCAD or BOSL. I would like this design to be fully parametric, and I'm hoping that the AI can generate this entire design without me needing to attach any starting code.

Could you please generate the OpenSCAD code for this design? I think it would be best if you generated different files for the Effector, Carriage, and a module file. I think having them broken up will make it easier for me to work with and customize.

Thank you!

I'm looking to generate some parametric connectors for building panels. I've got a rough idea laid out in a simple SCAD file, but I need something much more flexible and robust. I've attached the file.

Essentially, I need a system of cubic connectors that join panels along their edges and corners. The basic building block is a cube, and these cubes should be arranged with a gap between them. The attached file has them arranged in a kind of 3x3x3 configuration, but that's just a starting point. I want the overall dimensions of the panel connections to be controlled by parameters, not hardcoded.

Here's what I need in the final SCAD file(s):

*   **Parametric Cube Size:** The cubes should be defined by a parameter, say `cube_size`, that controls the length of each side.
*   **Parametric Gap:** The space between the cubes should also be a parameter, let's call it `gap_size`. This parameter should also be able to be zero if needed, in order to get a solid block (or a solid rod with a very long gap that equals zero).
*   **Overall Grid Size:** I want to control how many cubes are in each direction using a parameter like `grid_x`, `grid_y`, and `grid_z`. The basic layout should start from a corner, and the connectors should only go outwards.
*   **Connecting Rods:** There should also be rectangular prism connectors running between the cubes. I've started to make these in my file, but they should also be fully parametric based on `cube_size` and `gap_size`. Their length should always be `2*cube_size + gap_size`.
*   **Connector Type:** I want an additional parameter, `connector_type`, that allows me to choose different types of connectors. For instance, "corner" (like in the attached file, always using one cube in a corner as a start), "edge" (only cubes on one edge), "surface" (cubes on one surface), and "full" (all cubes). The connecting rods should also be generated only when necessary, depending on which type of connector is being used.
*   **Single Connector Output:** And, I need to be able to output *only one* of the connector blocks, not the entire grid. There should be a parameter called `connector_number`, which can output the first cube, the second, the third and so on, in an order I will define in the code.  I was thinking the first cube would be in the corner at 0,0,0, followed by the one on the x axis, then the y, the z, the xy, the xz, the yz and then finally the xyz.
*   **Parameter Defaults**:  Make sure default values for `cube_size`, `gap_size`, `grid_x`, `grid_y` and `grid_z` are used when these are not defined by a user, so that it is easy to test by just running the file. Also make sure that if `connector_number` is defined, `connector_type` is ignored.

I would prefer a single file if possible. I don't think I need any external libraries, or specific modules beyond what's in the basic OpenSCAD language. Thanks!

I'm looking to design a guitar neck support for when I'm working on my guitars. I have a basic idea in mind, and I'd like you to create a parametric OpenSCAD design for me.

Essentially, the support will consist of a rectangular base and a support section. The base should be a simple rectangular prism, and I'd like to be able to adjust its height. The support section should sit on top of the base, and should also be a rectangular prism with adjustable height and width. It also needs a v-shaped cutout running down its center, to cradle the neck of the guitar. I'd also like that v-shaped cutout to be parametric, adjustable in its depth and width, with the angles of the "V" remaining fixed.

I'd like all dimensions to be easily adjustable using parameters, and the design should be straightforward and easy to understand. I don't need any fancy features or complex shapes. I think it should be fairly simple, but I'm not sure how best to do the cutout. It would be great if you could also provide comments explaining each part of the code.

Could you please provide me with the OpenSCAD code for this design? I don't need any external libraries, just the core OpenSCAD functionality.

[Assistant]
guitar-neck-support.scad:
```
/* [Global] */

// The height of the base
base_height=5;

// The width of the support
support_width=80;

// The height of the support
support_height=40;

/* [Hidden] */
$fn=128;

translate([-5, -5, 0])
cube([support_width+10, 50, base_height]);

translate([0, 0, base_height])
difference() {
  cube([support_width, 40, support_height]);

  translate([0, 0, support_height-18])
  rotate(a=[90,0,0])
  linear_extrude(h=support_width/2, center=true, convexity=10, twist=0)
  polygon(points=[[support_width/2,0], [support_width,20], [0,20]], paths=[[0,1,2]]);

I'd like to create a customizable "peace sign" that can be 3D printed, and I want it to be parametric. Here's a breakdown of what I'm envisioning:

The design is fundamentally a ring with three bars coming inward. I'd like parameters for:

*   **Overall Diameter:** This controls the size of the outer ring.
*   **Height:** Controls the thickness/height of the sign.
*   **Wall Thickness:** Controls the width of the ring and the bars.
*   **Magnet Diameter:** The diameter of a hole in the back, for inserting a magnet.
*   **Magnet Thickness:** The depth of that magnet hole.
*   **Outside Resolution:** Controls the number of segments in the outer ring, for smoother curves. This could also allow for an octagonal ring instead of a circle.
*   **Inside Resolution:** Controls the number of segments for the internal void in the ring.

The design should include these features:

*   A ring (cylinder) as the base structure. There should be a hollow interior, also a cylinder.
*   Three bars that extend inward from the outer ring towards the center. One bar is horizontal and two others at 135-degree angles, they should be of the same width as the ring wall.
* A circular magnet hole on the back, centered and slightly inset within the ring thickness.

I'm not specifying materials, just dimensions.

I'd like to use OpenSCAD for this and would like to make sure all parameters are easily adjustable at the top of the file. I don't need any libraries at this time. Please let me know if you need any clarification!

Okay, I'm looking to design a ring light for photography, and I'd like to use OpenSCAD to make it parametric. I've got a basic idea, but it needs to be flexible enough to handle some different situations. I'd like this to be designed from scratch rather than making changes to existing code.

The core of it is a ring with two channels for LED light strips, kind of like a double donut shape. I'm planning to use flexible LED strips, the kind that are about 8mm wide and have a flat profile, these are the PVC strips you can find online. I need the channels to fit these strips snugly, but with a little wiggle room, so something around 8mm channel width and 5mm channel depth should work. I'd also need a way to run a power wire from the outside of the ring to the inner channel, so a hole for that. I would like to use the MCAD library, and in particular, the `boxes` module within that. I'm anticipating that this will require more than one scad file.

I'd like to be able to break the ring down into three pieces, mostly for printing on smaller printers. I want to include bolt ears on the three main parts so that they can be bolted back together after printing. This also means I need to design a sleeve for a dowel joint to keep the three parts in alignment. These dowels are going to be about 8.5mm in diameter. I'm anticipating using M5 nuts and bolts, so the ears should be designed to take these. M5 nuts are about 2.35mm thick and have a 5.5mm distance across the flats, and I'm planning to use standard 3mm bolts. Please include a slop variable so that the tolerances can be tweaked easily.

Finally, I also need a way to attach this whole ring to a camera. I've got a standard hot shoe adapter in mind, so I'll need to design a hot shoe with a way to connect to the ring. My thought is to use a dowel pin and screw joint on the main body of the ring, and I'm including a sleeve for the dowel in the current design. I'm thinking that the sleeve can also be a part of the hot shoe attachment.

Oh, and one more thing. I also need a small box for the DC power connector and some wiring. It doesn't need to be fancy, just a simple box with screw posts and a lid. The lid should have a hole for a DC barrel connector to protrude through, and it'd be nice if the connector was included as a separate module as well.
