I'm looking to create a parametric s-hook for my oven handle. I want to be able to adjust the size of the hook ends to fit different handle diameters.

The basic design is an s-shape, with two curved hook ends. One end will be larger to fit over the oven handle, and the other will be smaller, designed to hold onto a smaller bar, like a metal rack.  I'd like to be able to specify the inner diameter of both the large and small end. The hook also needs a body diameter, which is the thickness of the material.

A good starting point for sizing the small end is to make the inner diameter about 30% larger than the handle it's intended to grip, this is to ensure the opening is large enough to fit the handle through. So if I had a 27mm handle, the small diameter on the hook should be about 35mm, as in the example. I'd also want to control the diameter of the large end and the thickness of the hook material.

Could you generate a parametric OpenSCAD file for this? I don't have any code to start with, so it should be from scratch. I'm not using any particular libraries either, so you should not assume that I have any helper functions available.

S-Hook.scad:
```
/**
 * S-hook with different sized ends.
 */

// Large end inner diameter
diameter_large = 41;

// Small end inner diameter.
diameter_small = 35;

// Hook body diameter.
diameter_body = 5;

module s_hook(diameter_large=41, diameter_small=5, diameter_body=5) {
	$fa = 0.1;
	$fs = 0.25;

	assign(radius=(diameter_small / 2) + (diameter_body / 2), angle=60) {
		translate([radius, 0, 0]) rotate([0, 0, 180]) difference() {
			rotate_extrude() translate([radius, 0, 0]) circle(r = diameter_body / 2);
			translate([0, 0, -diameter_body / 2]) linear_extrude(diameter_body) pie_slice(r=(2 * radius) + (2 * diameter_body), a=angle);
		}
	}

	assign(radius=(diameter_large / 2) + (diameter_body / 2), angle=90) {
		translate([-radius, 0, 0]) rotate([0, 0, 0]) difference() {
			rotate_extrude() translate([radius, 0, 0]) circle(r = diameter_body / 2);
			translate([0, 0, -diameter_body / 2]) linear_extrude(diameter_body) pie_slice(r=(2 * radius) + (2 * diameter_body), a=angle);
		}
	}

}

module pie_slice(r=3.0, a=30) {
	intersection() {
		circle(r=r);
		square(r);
		rotate(a-90) square(r);
	}
}

s_hook(diameter_large=diameter_large, diameter_small=diameter_small, diameter_body=diameter_body);
```

Hey, I'm looking to create a customizable outer ring for a cryptex design I'm working on. I want the ring to have 10 faces, and each face should be able to display either text or an imported image.

For the text, I need to be able to set the font, bold, italic, size, spacing, and direction. I also need to be able to move the text horizontally and vertically, as well as rotate it. I want to be able to set a depth for the text which would either emboss or deboss the text depending on if the value is positive or negative.

For the images, I want to import png files. They should also have a set depth so that I can emboss or deboss them. The images should be able to be manipulated like the text by horizontal and vertical movement, and rotation.

I want to have a default set of settings for the text, but then also be able to override these settings for each individual face.

Could you generate the OpenSCAD code for this? I'm not familiar with OpenSCAD, so I want the code to be really easy to use, and would ideally have it work with the Customizer window in OpenSCAD, so I can adjust the settings through the GUI.

It'd be great if the code would also label each face with the number of the face for the preview.

/******************** DESCRIPTION ********************//*

Outer_Ring_Customizer_03    14/09/2022

This Scad file is for quick and easy creation of custom "Outter_Rings" for my cryptex design "Combination Safe 00" http://www.thingiverse.com/thing:586169

 I've made this file as simple as possible to use, so you don’t need to be familiar with OpenSCAD to use it, just follow the instructions below

This is the third version of Outer_Ring_Customizer. I have tried to make it as user friendly as possible my making all the setting, plus a few new ones, accessible via the Customizer window.*/

/********* HOW TO USE OUTER RING CUSTOMIZER **********//*

1)  If you're reading this you've already open the Scad file. Well done :)

2)  Open the "Window" menu (above) and select "Customizer".

3)  Inside the "Customizer" window that you have just opened, you will see a number of drop-down menus, with headings like "Input Text"

4a) If you would like to change the numbers on the ring to something different simply open the "Input Text" drop-down menu and replace the number in each text box with whatever you want.

4b) To change the style of the text use options inside the "Text Settings" menu. Inside the "Other Settings" menu you'll find the option to move or rotate the text/image around.

5)  Alternatively, you can import image files to use in place of numbers and letters. I have included a number of image file you can use however if you wish to use your own, read the section called "ABOUT USING IMPORTED IMAGE FILES" (below).

6)  "Text Settings" and "Other Settings" set the default values used for all ten faces. However, you can override these values by using the "Custom Settings" menus to give each face its own custom style.
    The "Custom Settings" menus are always active but when the sliders are dragged as far left as possible, they will use the default vales.

7)  When you've finished your design press the "Render" button F6. Rendering can take a while especially if your importing images. Once the render is complete, save your custom Outter_Ring as a STl file by pressing the "Export as STL" button F7 and choose a name and location for the new .stl file.

8)  You're all done!
 */
/********* ABOUT USING IMPORTED IMAGE FILES **********//*

Imported images are converted into depth values and embossed or debossed onto the ring. Black pixels have zero depth. White pixels have either positive or negative depth, depending on what value you gave the "Depth" setting.

    The image file manipulations listed below can be done with a very basic image editor, such as Microsoft Paint (which will already be installed on your PC)

1)  Images should be a [6:5] ratio (e.g., width=120pixels, hight=100pixels).  This will stop them being squashed or stretched when imported into OpenSCAD.

2)  I wouldn’t recommend using images much bigger than 120 x 100  as it will have a significant impact on preview & render times.

3)  The background colour of your image should be black so that it's flush with the surface of the ring. If your design is black on a white background, "invert" the colours.

4)  The images need to saved as .png files. OpenSCAD cannot read .JPG or any other image format.

5)  The images being to be used must be saved in the same folder as this scad file in order for the scad file to find them.

6)  To add an image to the ring simply open the "Input Images" menu and type the name of the image you wish to use into one of the text boxes*/

I'd like to create a design that produces an interference pattern from overlapping lines. I'm envisioning two sets of lines, each radiating from their own center point, but offset from each other, all within a rectangular frame. Each line will be a rectangle, and I'll want to control their height, width, length, and the spacing between each line. This should be in 3D, and I want to be able to control how thick the overall 3D design is.

Here are the specific parameters I'd like to control:

*   **`height`**:  The overall height of the 3D extrusion.
*   **`lineWidth`**: The width of each individual line.
*   **`lineLength`**: The length of each individual line (extending from the center point).
*   **`xOffset`**: The horizontal distance between the center points of the two line sets.
*   **`numLines`**: The number of lines in each set. This will determine the line density, and therefore how dense the interference pattern is.

I'm imagining a pattern that looks something like the sample I've seen, but I want more control over all of those aspects. I'd like this to be generated as an OpenSCAD design, and it shouldn't require any specific libraries.

zonk.scad:
```
// zonk resolution test

// height
height1 = 1;

// line width
width1 = .5;

// radius
radius1 = 40;

// offset
xoffset1 = 5;

// number of lines
lines1 = 60;

step = 180 / lines1;

module do_line(angle) {
	rotate(angle)
		square([width1, radius1 * 2], true);
}

linear_extrude(height= height1) {
	for (angle = [step : step : 180]) {
		do_line(angle);
		translate([xoffset1, 0])
			do_line(angle);
	}
}

Hi! I'm looking to design some custom sewing machine spools and spool clamps, and I'd like to use OpenSCAD for that. I’ve got a Singer Professional XL-1000, and it has some quirks with larger thread spools – the tension is too high, which leads to broken needles. I'm hoping these designs will solve that problem. I've seen some great examples out there, but I need something tailored to my specific machine.

For the spools, I need a design that can be easily adapted for different thread amounts, so it'd be great if it were parametric. The key dimensions I'm thinking of to start with are:

*   **spool_radius**: The main radius of the spool core, let's start at 5.6 mm.
*   **spool_height**: The height of the spool, initially at 60.0 mm.
*   **lip_radius**: The radius of the top and bottom lips, let's start at 8.8 mm.
*  **lip_height**: The height of the top and bottom lips, at 2.0 mm.
*   **spindle_radius**: The radius of the center hole, this should be around 3.6 mm.

The spool will have a cylindrical core and top and bottom lips that extend outwards. The lips should be wider than the core and the transition between the lip and the core should be smoothly tapered.

For the spool clamp, I also need it to be parametric, so I can make adjustments later. The key parameters I see are:

*   **id**: The inner diameter of the clamp. I need this to be 5 mm for my machine.
*   **od**: The outer diameter of the clamp, maybe around 8.5 mm to start.
*   **cut_w**: The width of the cut in the clamp, I'm thinking 1 mm as a starting point.
*   **h**: The height of the clamp, 5 mm should work.

The clamp will be a cylinder with a slit cut into the side that allows it to open slightly and grip the spool. It also has an internal hole which would fit on the machine.

Could you help me create two OpenSCAD files for these, one for the spool and another for the clamp? I don’t need anything too fancy, just a basic design with these parameters that I can adjust later.

With this spool you can re-spool thread from bigger spools, which have too much
mass and tend to cut off or break your needle. Unfortunately its not fully automatic,
because you have to use your fingers to guide the tread while respooling, to make
sure, that the spool is evenly filled, becuase the respooler is originally designed
to spool the under-thread-spool.

I'd like to create a parametric speaker enclosure, similar to what I've seen done with a project called NOMOON. It's a spherical design, and I want to be able to control a bunch of parameters. I'm looking for OpenSCAD code that I can use to generate the enclosure, and ideally, it would be able to handle the following:

**General Sphere Parameters**

*   The user should be able to either specify the internal sphere diameter directly, or the internal volume in liters, and the code should calculate the diameter from the volume if it's not provided.
*   I need to set the wall thickness of the sphere.
*   I'd also like to include a marking thickness which I believe will add decorative bands to the outside.
*   I would also like to have an additional trenching or carving depth to make the band detailing more pronounced.

**Speaker Hole & Mounting**

*   There should be a parameter to set the speaker hole diameter.
*   I also need a parameter to define the diameter of the inset area around the speaker hole (speaker mount diameter).
*   I also need to control how far the speaker mount is inset into the sphere.
*   The speaker hole should be angled, and I need a parameter to control the angle.
*   I want an option to create a notch for speaker terminals. If that is enabled I need to set the notch's width, height and how far it's inset from the speaker hole, as well as an angle to rotate the notch into position.
*  There should also be a parameter to compensate for the countersink depth using extra wall thickness.

**Screw Holes**

*   I need to define the spacing between diagonally opposing screw holes.
*  I also need the ability to define the number of speaker screw holes.
*  And of course, the diameter of the screw holes themselves.

**Bass Port & Bottom**

*   There should be an option to include a bass port or not.
*   If a bass port is included, I need to set the internal diameter and the length of the port. I would also like to set the wall thickness of the port.
*   If the bass port isn't being used, I need to be able to specify the diameter of a flat area on the bottom of the sphere for easy printing.

**Wire Holes**

*   I'd like the ability to add up to two wire holes, each with its own diameter and angle.

**Other Considerations**

*   I'd like the code to be configurable with `$fn` to control the sphere resolution.

Essentially, I want a flexible OpenSCAD script that can generate variations of this spherical speaker enclosure, so I can tune it to different drivers and printing needs. I hope that is clear enough, thanks.

I think I would benefit from the use of BOSL2 for its enhanced functionality; but if you think there is a better choice I will happily consider it.

Hi, I'm looking to generate a test print for evaluating my 3D printer's part cooling, specifically its ability to handle unsupported bridges. I've been using a simple cantilever-style test, but I'd like something a bit more flexible and customizable.

I'd like an OpenSCAD design that generates a series of cantilevered bars, each extending further than the last. The bars should be stacked vertically, with each level offset slightly from the previous one. Here are the parameters I'm thinking of, and I want all of them to be user adjustable:

*   **Maximum Overhang Length:** The length of the longest cantilever.
*   **Overhang Increment:** The amount each cantilever increases in length compared to the one below it.
*   **Bar Height:**  The height of each bar.
*   **Bar Width/Support Column Size:** The width of each cantilever bar, which should also be the size of the central supporting column (where it's attached to the base).
*   **Base Size:** The overall size of the base the structure sits on.

The basic idea is to have each cantilever alternate whether it starts at zero offset on one edge and extends forward or starts extending from a certain offset to the other edge. If it is more convenient, it'd also be okay to just have it extend forward from one side rather than alternate. Each bar should be a rectangular prism and each level of the print should have a unique height.

Could you help me generate the OpenSCAD files for this design? I'm looking for something I can easily tweak for different cooling tests.

[Assistant]
Cantilever_Test_v1-0.scad:
```

// Length of longest overhang
_maxOverhang = 30;

// Length difference between each overhanging bar
_increment = 3;

// height of each bar
_height = 2;

// size of the center column (also the width of each bar)
_size = 4;

module make() {
	maxLevel = floor(_maxOverhang/_increment);
	union() {
		for(level = [0:maxLevel]) {
			assign(length = level * _increment) {
				translate([level%2==0 ? -length : 0, 0, _height * level])
					cube([length+_size, _size, _height]);
			}
		}

		// base
		translate([-_size,-_size,0])
		cube([_size*3,_size*3,0.3]);
	}
}

make();

I'd like to design a candle-powered carousel, but I need help creating the OpenSCAD files. I have a basic idea of the parts and how they fit together, but I'm not very good with the coding.

The carousel will have several parts: a base, a top, a fan, a shaft, and a decorative snowflake piece. The base will hold a candle and have a lip for the protective glass. The top will mirror the base, and also have a lip for the glass. The fan will sit on top of a shaft, which will be supported by a hook. And then, the decorative snowflake can be mounted anywhere.

For the base, I envision a cylindrical base with a raised candle holder section in the center. I'd like to have a lip that extends out to support the glass cylinder and a recessed section inside. I'd like to have the ability to have squares or circles in the recessed section of the base.

The top is essentially the same design as the base but no candle holder section. It needs the lip for the glass and the recessed section with the square/circle option.

The fan will be a circular design with several blades. I'm thinking something like 12 fan blades equally spaced, each a little like a curvy propeller.

The shaft will be a simple cylinder and needs a hook to hold it at the appropriate position. I'd like it to be designed so that it's easy to attach the fan to the shaft.

The snowflake will be a six-pointed star shape, created by combining rotated cubes and some smaller connecting details.

The overall design should be parametric, with variables for:

*   `glass_radius`: The radius of the glass cylinder (default to a standard 2-liter bottle radius - 54.6mm)
*   `glass_height`: The height of the glass cylinder (default to standard 2-liter bottle height - 120mm)
*   `candle_radius`: The radius of the candle holder base (default 20mm).
*   `candle_height`: The height/depth of the candle holder base (default 10mm).
*   `design_pattern`: A boolean variable to switch between square and circle patterns in the base and top (default to true, meaning squares).
*   And then a part variable. This will be "first", "second", "third", "fourth", or "fifth" for the base, top, fan, shaft, and snowflake, respectively.

Could you please generate the OpenSCAD code for each part, using these parameters and descriptions? Could the design also use the `linear_extrude` and `rotate_extrude` features?

I'm not asking for any external libraries. Just a parametric design using base OpenSCAD features.

Hey, I need help designing a customizable witch or wizard hat. I've got some figurines I want to put hats on, and I'd like the design to be parametric so I can easily adjust it for different sizes.

Specifically, I'm envisioning a classic witch hat shape: a cone for the main body and a flat brim. Here's the basic structure and the parameters I'd like to be able to control:

*   **Height:** The overall height of the cone part of the hat.
*   **Cone_Radius:** The radius of the base of the cone.
*  **Brim_Radius:** The radius of the brim of the hat
*   **Brim_Thickness:** The thickness of the brim
*   **Hole_Radius:** The radius of the hole at the base of the hat, where the figurine's head goes in.

I want the cone to be a true cone and the brim to be a flat cylinder. I don't need any complex curves or shapes.  Could you create an OpenSCAD file that lets me adjust these parameters? I'm new to coding, so please keep it simple!

[Assistant]
Customizable_Witch_Hat.scad:
```
Height = 14.4;
Cone_Radius = 6;
Brim_Radius=9;
Brim_Thickness=1;
Hole_Radius=5;

	translate([0,0,0]) scale([1,1,Brim_Thickness]) cylinder(r=Brim_Radius);
	translate([0,0,0]) scale([1.2,1.2,1.2]) cylinder(r1=Cone_Radius/1.2, r2=0, h=Height/1.2);
	}
	union()
	{
	translate([0,0,0]) scale([1,1,1]) cylinder(r1=Hole_Radius, r2=0, h=Height/1.2);
	}

Hi, I'm looking to design a case for a Blizzard authenticator, you know, the little digipass thing. I'd like the case to be parametric so I can adjust it if needed. I want to be able to specify the overall dimensions (height, width, depth), how much larger the case should be than the authenticator itself, the position and size of the button cutout, screen cutout and the keyring hole. I'd like to use rounded corners on the body of the case too.

I'd like to be able to specify the following:

*   `h`: Total height of the authenticator (and the case should fit this).
*   `w`: Total width of the authenticator.
*   `d`: Total depth of the authenticator.
*   `oversize`: How much larger the case should be than the authenticator in all directions. This will allow me to make a slightly looser or tighter fit.
*   `chord_w`: The width of the rounded end on the keyring side of the authenticator.
*   `keyring_hole`: Whether to include a keyring hole (true/false).
*   `project_keyring`: How far the keyring hole extends (or projects) from the main body.
*   `keychain_dia`: The diameter of the keyring hole.
*   `keychain_outset`: How far the keychain hole extends beyond the body of the case.
*   `button_d`: How high the button sticks up on the authenticator (to be used for the cutout).
*   `button_dia`: The diameter of the button (to be used for the cutout).
*   `button_inset`: How far the center of the button is from the edge of the device (to be used for the cutout).
*   `two_buttons`: Whether to create cutouts on both sides for buttons. This might be needed in the event that the case can be put on upside down.
*   `lcd_w`: How wide the screen is (for the cutout).
*   `lcd_h`: How high the screen is (for the cutout).
*   `lcd_inset`: How far the edge of the screen is from the edge of the device (for the cutout).

I would also like to include a dovetail joint on the case so I can easily combine it with another part later. I'd need the dovetail to be parametric in terms of width, depth, angle, and z-angle. I'd want to have a separate module for this dovetail. I think I need a module for the main body of the authenticator as well as another module for the case with cutouts, then one more for the dovetail as well. The case should make the cutouts for all the buttons and the LCD, but I would like an option to turn that off. The rounded shape on the keyring side should also be parametric.

Could you provide me with a set of OpenSCAD files that achieve this? I don't need any libraries for this.

Hey, I need an OpenSCAD design for a rotor protector for a quadcopter. I've got some basic parameters in mind and a general shape I'm going for, inspired by this design I found: `asctec_pelican_rotor_protector.scad` (I've included it below for your reference).

Essentially, it's a quarter-circle section of a ring with a supporting spoke going to the center. I'd like this to be parametric so I can easily adjust the size and other features later.

Here are the key parameters I need to control:

*   **`thickness`**:  The width of the ring and the spoke (the structural thickness).
*   **`height`**: The z-height (vertical thickness) of the protector.
*   **`outer_radius`**: The outer radius of the ring.
*   **`hole_diameter`**: The diameter of the screw holes for mounting.
*   **`hole_distance`**: The diagonal distance between the centers of the mounting holes (they're arranged in a square pattern).

The design should have:

*   A quarter-circle section with a ring-like structure (i.e., an outer circle and an inner circle, with thickness defined above.)
*   A spoke connecting the midpoint of the outer arc of the ring to the center, for added support.
*   Four mounting holes arranged in a square pattern centered on the origin of the quarter circle section and using the `hole_distance` parameter.
*   Everything should be designed using modules to make it easy to modify and re-use.

I'm also trying to keep things relatively simple, so I think I can handle making multiple copies and rotations of these quarters myself to get a full protector.  I don't need the full thing in a single part for this.

Here's the code I was basing it off:

```
$fn = 50*1;

// Width of the beams
thickness = 5;

// z-Height of the part
height = 5;

// Radius of the outer circle
outer_radius = 150;

// Diameter of the holes for the screws
hole_diameter = 3.3;

// Diagonal distance between the holes
hole_distance = 19;

module outer_quarter_circle() {

	difference() {

		linear_extrude(height = height)
		circle(r = outer_radius);

		translate([-outer_radius/2,-outer_radius/2])
		linear_extrude(height = height)
		square([outer_radius,outer_radius], center = true);

		translate([outer_radius/2,-outer_radius/2])
		linear_extrude(height = height)
		square([outer_radius,outer_radius], center = true);

		translate([-outer_radius/2,outer_radius/2])
		linear_extrude(height = height)
		square([outer_radius,outer_radius], center = true);

	}

}

module inner_quarter_circle() {

	difference() {

		linear_extrude(height = height)
		circle(r = outer_radius-thickness);

		translate([-outer_radius/2,-outer_radius/2])
		linear_extrude(height = height)
		square([outer_radius+2*thickness,outer_radius+2*thickness], center = true);

		translate([outer_radius/2,-outer_radius/2])
		linear_extrude(height = height)
		square([outer_radius+2*thickness,outer_radius+2*thickness], center = true);

		translate([-outer_radius/2,outer_radius/2])
		linear_extrude(height = height)
		square([outer_radius+2*thickness,outer_radius+2*thickness], center = true);

	}

}

module Hole(diameter, depth, placement=[0, 0, 0]) {

	placement_offset=depth < 0? [0, 0, depth] : [0, 0, 0];
	translate(placement+placement_offset)
	linear_extrude(height=abs(depth))
	circle(r=diameter/2);

}

difference() {

	union() {

		difference() {
			outer_quarter_circle();
			inner_quarter_circle();
		}

		linear_extrude(height = height)
		circle(r = hole_distance/2+hole_diameter/2+thickness);

		rotate([0,0,-45]) {
		translate([0,outer_radius/2,0])
		linear_extrude(height = height)
		square([thickness,outer_radius-thickness/2], center = true);
		}

	}

	Hole(hole_diameter, height, [hole_distance/2, 0, 0]);

	Hole(hole_diameter, height, [0, hole_distance/2, 0]);

	Hole(hole_diameter, height, [-hole_distance/2, 0, 0]);

	Hole(hole_diameter, height, [0, -hole_distance/2, 0]);

}
```

Could you create that for me?

I'm looking to design a customizable LED strip for a project. I've got a basic idea, but I'd like some help fleshing it out with a parametric OpenSCAD model.

The core of the design is a strip that holds a specified number of LEDs. Each LED should be represented by a small cylindrical base, topped with a rounded dome. I've got some rough dimensions: the base of each LED is about 3mm radius, 1mm high, then a cylinder with a radius of about 2.5mm and a height of 5.1mm, then a 2.5mm radius sphere on top. The whole LED shape should be a hull of those parts.

The LEDs are to be spaced evenly, with about 15mm between each LED (center to center). The strip itself should be a rectangular base, with a thickness of 5mm, a width of 8mm, and a length based on the number of LEDs, plus some extra length on either side for mounting. Specifically, I need 15mm of extra strip length before the first LED and 5mm of extra strip length after the last LED. Also, there should be 10mm thick end-caps at both ends which are of equal width and height as the base strip, except they extend 5mm upwards beyond the base.  Additionally, there should be a thinner strip (3mm thick, 2mm height) running along the bottom of the main strip.

Finally, I need two screw holes at the ends of the strip.  These should be countersunk through the main strip. I was thinking that a 1.8mm radius cylinder, rotated 90 degrees and 10mm deep would work. The centers of these should be 5mm in from each end of the main strip along the length and 5mm up from the bottom of the main strip (or 5mm from the bottom of the main strip + the thin support strip, if that is easier).

I'd like the design to be parametric, where I can easily specify the number of LEDs I need. Could you generate the OpenSCAD code for this? I'm not looking for any extra libraries this time.

    *   `Height`: Height of the holder above the base
    *   `BaseHeight`: Height of the base
    *   `BackAngle`: Angle of the back of the holder (0-15 degrees)
    *   `InnerAngle`: Angle of the inner part of the holder (0-3 degrees)
    *   `WallThickness`: Thickness of the walls
    *  `OutsideBand`: An offset for the inner cutout of the front of the holder.
*   **Charger Dimensions:**
    *   `ChargerX`: Width of the charger
    *   `ChargerZ`: Thickness of the charger
    *   `CSlack`: Tolerance/gap around the charger
    *   `CScrewDiameter`: Diameter of the charger mounting screw
    *  `CScrewCountersinkDiameter`: Diameter of the charger mounting screw countersink
    * `CScrewCountersinkDepth`: Depth of the charger mounting screw countersink
    *   `CScrewHoleLeft`: Boolean for whether to include a screw hole on the left of the charger hole.
    *   `CScrewHoleRight`: Boolean for whether to include a screw hole on the right of the charger hole.
*   **Mounting Parameters:**
    *  `holediameter`: Diameter of the wall mounting holes.
    * `countersink`: depth of the wall mounting hole countersink.
    * `HoleDepthModifier`: An offset for depth of the wall mounting hole.
*   **Text Parameters:**
    *   `TextYModifier`: Vertical offset for text position.
    *   `font`: Font for the engraved text, using a font from the `Write.scad` library. I'd like to be able to specify "write/orbitron.dxf", "write/Letters.dxf", or "write/BlackRose.dxf".
    *   `font_size`: Size of the font.
    *   `text_depth`: Depth of the engraved text.
    *  `text`: The text to engrave.

I'd like the design to include the mounting holes on the back of the holder and the screw holes and countersinks for the charger. Also, could you ensure that the code uses the `Write.scad` library?

I'd like to design a parametric bag clip, similar to the one I saw on Thingiverse, but I want to start from scratch and I have some specific requirements. I want to be able to adjust all of the important dimensions, and the design should consist of two interlocking pieces, an "inside" and an "outside" part.

Here are the parameters I need to control:

*   **`part`**: A string that specifies if I'm generating the "inside" or "outside" piece. This would be a dropdown or similar in a customizer, with options like "Inside" and "Outside".
*   **`_length`**: The overall length of the clip, in millimeters. I need to be able to specify this as an integer or a decimal number between about 30 and 360 mm
*   **`_width`**: The width of the clip (thickness) in mm.
*   **`_outsideThickness`**: The thickness of the material on the outside clip piece, in millimeters.
*   **`_insideThickness`**: The thickness of the material on the inside clip piece, in millimeters.
*   **`_hingeGap`**: The gap between the inside and outside pieces at the hinge, in millimeters. This can be positive, zero, or negative to control how tightly the parts fit together.
*   **`_labelText`**:  A string of text that will be placed on the outside of the clip. If empty, no text should be rendered.
*  **`_labelFont`**:  The font that will be used for the label text. This should be selected via a dropdown and come from a library I'll specify later. Let's include the ability to use these options: "Orbitron", "Basic", "KneWave", "BlackRose", and "Braille".
*   **`_labelThickness`**: The depth of the label. Positive values will extrude the label, negative values will emboss it.
*   **`_labelHeightPercent`**: The height of the label as a percentage of the overall clip width. Should be an integer value from 1 to 100.
*   **`_labelDirection`**: 0 or 1. If 1, the text starts at the hinge; if 0, it starts at the clip end.
*   **`_labelSpace`**: The space between letters in the text label, as a floating point value.
*   **`_curvature`**: A number between 10 and 100 (inclusive) that controls the curvature of the clip. 10 would be a very flat clip, and 100 would be a semicircle.
*   **`_hingeDiameter`**: The diameter of the hinge, in millimeters.
*   **`_hingeAngle`**: The angle covered by the hinge section, in degrees. This should be a value between 180 and 300 degrees.
*  **`_clipAngle`**: The angle covered by the clip end, in degrees. This should be between 90 and 180.
*   **`_clipExtension`**: The amount in mm that the inner clip is longer than the outer, to help control the tightness of the clip closure.

I need the following modules to do the work of creating the clip:
* `smallArc`: Generates an arc with specified inner and outer radii, angle, and depth. This doesn't include rounded ends.
* `roundArc`: Generates a similar arc but with rounded ends.
*   `outerClip`: Generates the outside part of the clip, including the main curved body, hinge, and clip section, as well as optional label.
*   `innerClip`: Generates the inside part of the clip with the correct hinge and an extended body to help close the clip.
*   `make`: A module that instantiates either the inner or outer clip based on the `part` variable, and also sets up the necessary offsets so that the center of the main arc is located at 0,0,0.
I would like this to be parametric, so that I can adjust the size of the clip.  For the fonts, please use the `write/Write.scad` library, since it has some fonts I would like to use. I expect to run the code with OpenSCAD. I also expect that your code will define all of the above-mentioned variables as well.

I'm looking to design a wall-mounted hook for hanging shop vac tubes, and I want it to be parametric so I can easily adjust it for different tube sizes. I'd like to have a couple of options for the wall plate: one plain and one with a more decorative design.

Specifically, the design should include:

*   **A Hook:** This part will hold the tube. It should be a sort of a wedge-shaped structure with a cutout that matches the tube's diameter. I need to be able to specify the tube's outer diameter (OD), the depth of the wedge, and the total height of the hook.
*   **A Wall Plate:** This is the part that mounts to the wall. I want to have two designs for this:
    *   **Plain Plate:** A simple rectangular plate. I need to specify the thickness of the plate and the overall height.
    *   **Fancy Plate:** A more decorative plate with rounded corners created using `hull()` to smoothly transition between a set of cylinders, and additional sets of cylinders that connect each other smoothly as well.
*   **Mounting Holes:** There should be two mounting holes in the wall plate for screws. I need to specify the diameter of the holes, the distance between the holes, and the inset from the edges of the plate. I also need to add a small recessed counter bore and relief pockets in the back of the plate.
*   **Offset:** The hook part should be offset slightly from the wall plate, and I need to be able to specify this offset distance.

I'd like the design to be created in OpenSCAD. Please use appropriate $fn values for generating smooth curves and circles.

I'm hoping for a solution that includes some comments that explain what each section does. I'm thinking that two separate .scad files would be easiest - one for the mounting plate, and one for the main assembly. However, if you can do everything in one file, that's fine too. I'd also like to be able to toggle between the fancy and plain plate options using a simple variable.

I'm open to suggestions on how to improve this design as well if you have any. Thanks!
