I want to create a box for storing Nintendo DS game cards. I've got a few specific requirements for how it should look and function. I’d like the design to be parametric, meaning I can easily adjust dimensions and other values.

The box needs to hold a variable number of DS game cards, let's say from 1 to 20 cards. There should be enough space between the cards so the user can easily see each of them. I want to be able to adjust the space between cards, as well as how much the first card is visible.

The dimensions of the cards are approximately 34.95mm long, 32.75mm wide, and 3.8mm thick. But I want to add some extra space around each card, let's call it "fuzz," of 0.7mm on each side. The design should account for this extra space in the box.

There needs to be a groove at the bottom of the box. This groove is meant for a rubber band to hold the cards in place during transport. The height and width of this groove should also be adjustable, and should default to about 2mm high and 3mm wide. The box's overall height is dictated by the number of cards, and additional box height should also be a variable that can be easily changed, defaulting to 15mm. I want rounded corners on the main box, using a sphere radius to smooth them. Default to 3.

Finally, the main box should have a cutout to reduce material and weight. I'd like to control how much of a cutout there is, say with a value from 0 to 1 (where 1 is a full cutout, 0 is no cutout). The cards themselves should be positioned so that the entire face of the first card is visible.

Can you generate an OpenSCAD file (or files, if needed) that includes these features and parameters? I'm expecting the design to use the hull() operation, and be a "difference" of a hollowed out box with card slots and a rubber band groove. I'm not using any custom libraries so no need to account for that.

Alright, I've got a really cool idea I'd like to turn into a 3D-printable design. I'm working on a device that uses light-sensitive resistors, specifically CdS cells, to create a thermal image that you can feel. Basically, when light hits the cells, they heat up and that heat map can be used to represent an image. I've built a basic prototype with a 5x5 array, but I want to make something more practical and robust.

So, here's the gist:

I need an OpenSCAD design for a handheld device that houses an array of CdS cells. This will be the "sensor" part of the device. This array will need to be supported by a base, probably plastic of some kind. I need this to be parametric so I can adjust things later.

Here's what I'm thinking for parameters:

*   **`cell_rows`:** The number of rows in the CdS cell array (e.g., 5, 8, 10 etc.).
*   **`cell_cols`:** The number of columns in the CdS cell array (e.g., 5, 8, 10 etc.).
*   **`cell_diameter`:** The diameter of each CdS cell (in mm).
*   **`cell_spacing`:** The spacing between the center of each CdS cell (in mm).
*   **`base_thickness`:** The thickness of the base supporting the array (in mm).
*   **`wall_thickness`:** The thickness of any outer walls or housing (in mm).
*   **`overall_width`:** The width of the entire sensor assembly.
*   **`overall_height`:** The height of the entire sensor assembly.
*   **`overall_depth`:** The depth of the entire sensor assembly.
*   **`corner_radius`:** The radius of any corner rounding (in mm).
*   **`battery_type`:** A choice of common battery types, and the model should automatically accommodate the geometry of that battery type. Something like `AA`, `AAA`, `9V`, and some button cell sizes might be good.
*   **`battery_compartment_depth`:** The required depth for the battery compartment
*   **`switch_hole_size`:** the hole size for a typical 3PDT toggle switch.
*   **`switch_hole_depth`:** The depth of the switch hole.
*   **`usb_charge_port`:** An option to include a USB-C or micro-USB port that can handle charging a battery.

I'd like a few design constraints.

*   The CdS cells should be flush with the top of the base or slightly recessed.
*   The design needs to accommodate the battery specified via `battery_type` and a switch.
*   There should be an optional housing for electronics and wiring.
*   If a USB port is added, it should be on the side of the device and properly recessed.
*   I'd like to have rounded corners on the housing.
*   The design should be able to be split into two parts, perhaps a "sensor" top and a "base" bottom, for easy assembly.

I think that's everything. Let me know if you have questions. I'd like the output as an OpenSCAD file. I'm not sure if this needs a custom library, but I know there is a battery library in MCAD, that might be useful.

I'm looking to create a customizable set of cube gears that interlock and animate. I need a few different parts: a center block, two differently sized bevel gears, and pins to hold it all together.

Here's a breakdown of what I need:

*   **Center Block:** A cube with cutouts on each face that fit the gear assemblies. The cutouts should be angled to match the gear's mounting position.
*   **Large Gear:** A bevel gear with the option to add text on the flat sides perpendicular to the gear face. It connects to the center block via pins. I want to be able to customize the text on each of these sides.
*   **Small Gear:** A smaller bevel gear that meshes with the large gear. It also connects to the center block with pins.
*   **Pins:**  Cylindrical pins with a lip on each end to secure the gears to the center block. They should be slightly longer than the combined thickness of the gear and cutout, and should fit snuggly (but not too tight) in the pinholes.
*   **Assembly:** An assembly module that will position and rotate the gears correctly. It would be nice if this could also be animated for preview purposes.

Here are some parameters I want to control:

*   **Object:** A selector to render any one of the individual parts or the assembly. (Center, Large Gear, Small Gear, Pin, Assembly)
*   **Gear Type:** I would like to use pre-determined tooth counts and gear ratios. I'd want options for 18 & 9 teeth, 9 & 6 teeth, and 18 & 15 teeth. The gear parameters should be calculated from an algorithm or look-up table, or the provided constants in this message.
*   **Cube Size:** The overall size of the cube structure.
*   **Pin Tolerance:** A variable to adjust the fit of the pins (a larger number means a looser fit).
*  **Pin Gap Ratio:** The ratio between the pin's length that's inside the gears and the pin's shaft diameter.
*  **Backlash:** Space between gear teeth to keep them from binding.
*   **Text:** Custom text for the large gear's flat sides. This will include three separate words.
*   **Font:** Customizable font for the text on the large gear.
* **Build Plate Size:** Support for different printer sizes.

I need to use the `involute_gears.scad` module from the `MCAD` library for the bevel gears. I'll also need something like the `Write.scad` module to be able to render text from a DXF font (like the included example uses, `Letters.dxf`). I'll also need something to define the pin geometry like the example code uses.

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

I want to design a golf tee that can have custom text added to it. I've got some basic ideas for the shape already.

The tee itself should consist of three main parts: a short, wide cylinder as the base, a sloped, cone-like section that transitions to the tee peg, and the tee peg itself which should be a smaller cylinder. The tee peg's top should have a narrow, rounded top. The base cylinder should have a flat top.

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

*   The text itself (of course!)
*   The font used for the text (I'd like to be able to specify a .dxf file for the font). I'll be using a custom font, so I'll have to provide that later.
*   The size of the text, which should be modifiable
*   Spacing between the letters of the text
*   The height of the main body of the tee (the height of the cylinder portion of the tee)
*   The radius of the base cylinder
*   The length and radii of the conical section between the base and the tee peg.
* The radii of the tee peg
*   The overall height of the tee (so it's easy to set the text location)

The text should be wrapped around the tee, so each letter is upright as it goes around. It should begin at the same z-height as the top of the base cylinder, or slightly below that.

I'm not sure if it would be easier to have the text as a separate module (it probably would be!).

For the text generation, I'd like to use the `write/Write.scad` library.

Hey, I'd like to design a golf tee with some customization options. I need it to have a main cylindrical body, a wider base with a rounded bottom, and a thinner, tapered top section. I'd like to add customizable text that's wrapped around the main cylinder.

Here's what I'm thinking:

**Core Tee Design:**
*   A main cylinder that's about 12mm high and 1.5mm in radius.
*   A base that's a short, hollow frustum (cone with top and bottom cut off). The frustum should be 2mm high, have a bottom radius of 2.5mm, a top radius of 1.5mm. I need the bottom of the frustum to be rounded - maybe using a partial sphere to create that rounded bottom. This piece should be centered on the end of the main cylinder.
*   A tapered top section, starting at the top of the main cylinder, that's 6mm high, tapering from 1.5mm radius to 0.2mm radius.
* All cylinders and spheres should have $fn=50 for smooth curves

**Text Customization:**
*   I'd like an option to enable or disable the text.
*   The text should be wrapped around the main cylinder of the tee.
*   The text should be able to be any text.
* I want to choose the font from a predefined list - "Letters.dxf", "orbitron.dxf", "BlackRose.dxf", and "braille.dxf". The default should be orbitron.dxf.
*   I need to control the size of the text, with a default height of 2.
* There also should be space between the letters of 1.3mm by default.
* The text should use the `write/Write.scad` library.
* The text should be placed at `[0,6,-26.5]` be a radius of 7mm, and a height of 66mm, be rotated 90 degrees, have a thickness of 1.3, and a boldness of 1.
* The text should be a cylinder with a letter cut out.

I think that's everything, let me know what you think.

I'm looking to create a rounded rectangular case, something similar to a small box with rounded edges, that will open along one side like a clamshell. I want it to be parametric so I can easily adjust the dimensions.

I have a basic idea of how to create the rounded cube using the `hull()` function with spheres, but I need help putting the whole thing together with a hinge and a way to close it.

The design should have the following features:

*   A main body consisting of a rounded rectangular box.
*   A lid, also a rounded rectangular box, which mirrors the main body and is connected by a hinge. The hinge should be integrated, not requiring extra parts.
*   A lip/edge on the lid to allow it to close securely onto the base.
*   The box should be hollow, with a specified wall thickness.
*   The parameters I need to be able to adjust are:
    *   overall x, y, and z dimensions (length, width, and height)
    *   rounding radius for the corners
    *   number of facets for the sphere approximations (to adjust smoothness)
    *   wall thickness
    *   hinge thickness
    *   lip size

I’m not super particular about the specific hinge design; something simple and functional is fine. I'd like the box to open along the y-axis. The lid should connect along the top edge and rotate along that edge.

I'd really like for this to be a single, well-organized OpenSCAD file that includes all of the necessary modules. I'm comfortable using modules rather than classes to avoid having to install a separate library like dotSCAD.

I'm looking for an OpenSCAD design for a customizable cable junction enclosure. I'd like it to be a clam-shell design, so two halves that fit together, allowing cables to be placed inside without needing to disconnect them. I need to be able to adjust things like the overall size, the number and size of cable entry/exit holes, and how the two halves are fastened together.

Specifically, I'd like to be able to set:

*   **Component:** Whether I'm generating the case, the lid, or both for visualization.
*   **Number of Cables:** The number of cable entry/exit points around the circumference.
*   **Cable Diameter:** The diameter of the cables entering or exiting.
*   **Overall Height:** The total height (depth) of the enclosure.
*   **Enclosure Diameter:** The overall diameter of the enclosure.
*   **Number of Standoffs:** The number of standoffs for securing the two halves with screws.
*   **Standoff Inner Diameter:** The diameter of the screw hole within the standoff.
*   **Mounting Holes:** Options to include mounting holes in the center, top, bottom, left, and right of the case, with adjustable diameters for each.

I'm also thinking there should be a few 'advanced' options I can control:

*   **Wall Thickness:** The thickness of the enclosure walls.
*   **Lip Thickness:** The thickness of the inner lip on the lid that mates with the case.
*   **Tolerance:** A small gap between the lid lip and the inside of the case to prevent it from being too tight.
*   **Standoff Outer Diameter:** The outer diameter of the standoffs (I don't expect I'll need to change this often.)
*   **Standoff Angle Offset:** The angle offset of the standoffs from the cable entry holes, so I can move them if needed.
*   **Countersink:** Option for countersunk holes in the lid.
*   **Countersink Diameter:** Diameter of the countersink.
*   **Countersink Depth:** Depth of the countersink.

For printing, it should be easy to print without supports. I would like the standoffs to be in a circle evenly spaced around the inner edge of the enclosure. The cable holes should be cutouts. I also think it would be good for the cable holes to use sphere-cutouts, as mentioned in the provided documentation, instead of cylinders so that it is easier to seal with some compound. Please provide separate SCAD files for the case and lid, as well as a single file that can display both for visualization. I don't need any external libraries for this, just standard OpenSCAD functionality.

Hey, I'm looking to design a golf tee with some text wrapped around the middle section, and I'd like it to be parametric so I can easily adjust things like the text, size, and spacing.

Essentially, I want a golf tee that has a standard shape: a thin, cylindrical base, a wider, frustum-shaped middle section, and then a thinner, peg-like top. I need the ability to control the radii and heights of each section, and the text should be extruded outwards (or inwards, I'm open to either) from the middle frustum section.

For the text, I want to specify:
- The text itself (obviously!)
- The font to use. I'm hoping you can use some standard fonts or ones from a library that is easy to integrate, or maybe even create a simple text rendering system. I can supply an image if it makes more sense for me to draw the font.
- The size (height) of the text.
- The thickness of the text extrusion.
- The spacing between the letters.
- The vertical position of the text on the frustum.

Additionally, I'd want parameters to control:
- Overall tee height
- Diameters and heights of each section (base, frustum, top).
- The rotation of the tee, and also the rotation of the text.
-  The ability to have no text.
-  A color parameter for the tee (and maybe text).

I'd like the whole thing to be a single module where all these parameters can be set. I know that some libraries exist for text rendering, so you could use those to start with, maybe even the `write` library. The library also has options to control font boldness, so include that too.

Could you generate the OpenSCAD code for this?

I need an OpenSCAD design for a small cube with cutouts on each face. Two opposing faces should have an "M" cutout, and the other two opposing faces should have an "O" cutout.  The cutouts should go completely through the cube.

The design should be parametric, so I can easily adjust the dimensions of the cube, the size of the cutouts, and also how deep the "M" cutouts go (they will need to be less deep than the cube in order to create the correct letter form).

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

*   `size`: The overall side length of the cube, in centimeters.
*   `M_Slit_Width`: The width of the cutouts that form the "M", in millimeters.
*   `M_Slit_Height`: The height of the cutouts that form the "M", in millimeters.
*   `O_Width`: The width of the "O" cutout, in millimeters.
*   `O_Height`: The height of the "O" cutout, in millimeters.
*   `Clip_O_To_Match_M_Slits`: A boolean flag (0 or 1). If 1, the edges of the "O" cutout that go toward the "M" edges should be clipped to the same depth as the "M" cutouts. If 0, the O should go all the way through.
*   `Upside_Down`: A boolean flag (0 or 1). If 1, the cube should be flipped upside down (along the Z axis).

The design should be based on a central cube and then use `difference()` operations to remove the cutouts. The "M" should be made from multiple cubes that are subtracted.

It shouldn't rely on any external libraries.

Hey, I'm trying to design a parametric terracotta pot in OpenSCAD, and I could really use some help. I want the pot to have adjustable height, radius, and drainage hole size, so I can easily create different sizes. I've got a basic idea of how I want it to look, kind of like a traditional terracotta pot with a bit of a lip at the top and a base.

Specifically, I'm thinking the pot will have a main cylindrical body, a slightly flared lip at the top, and a drainage hole at the bottom. I also want to create a separate, matching base plate that can be placed underneath the pot.

Could you create the OpenSCAD files for this? I need the code to be fully parametric based on the variables height, radius, and drainHole. I'd also like a way to control the smoothness of the curves, maybe using the $fn variable, but I'd want that to be a user-defined variable too. I think it's called `$fn` in OpenSCAD. I'd also like the base plate to have a slight lip where it contacts the main pot to prevent it from sliding off the main pot.

Ideally, the files should include modules for each part - the main pot (including the lip and internal cavity), the drainage hole, and the base plate so that they are clear and modular. The overall design should be very similar to the `parameticPot.scad` file I included. I don't need any complex features, just a good, clean, parametric model of a simple terracotta pot.

I'm not using any libraries right now, so all code should be pure OpenSCAD. Let me know if you need any clarification on what I'm trying to do!

[Assistant]
parameticPot.scad:
```
height = 50;
radius = 30;
drainHole = 5;

$fn=100;

// for the outside of the pot
module outside()
{
	cylinder(height, radius*0.9, radius, false);

	translate([0,0,height])
	cylinder(height*0.3, radius*1.1, radius*1.1,true);
}

// for the inside of the pot
module inside()
{
	translate([0,0,height*0.1])
	cylinder(height*1.2, radius*0.8, radius*0.955, false);
}

//drainage hole
module hole()
{
	translate([0,0,-1])
	cylinder(height*1.2, drainHole, false);

		translate([0,0,height*0.1])

I'd like to design a parametric hyperboloid structure in OpenSCAD, and I'm hoping you can help me generate the necessary code.

The core of the design will be a hyperboloid created using a ruled surface. The surface is defined by two elliptical paths, one at the bottom and one at the top. The lines connecting points on these ellipses form the structure. I'd like to be able to control several parameters:

*   **Height:** The overall height of the hyperboloid.
*   **Bottom Radius:** The radius of the ellipse at the bottom.
*   **Top Radius:** The radius of the ellipse at the top.
*   **Phase Angle:** A phase shift between the bottom and top ellipses, causing the hyperboloid to twist. This angle is in degrees.
*   **Thickness:** The thickness of the struts (lines) forming the ruled surface.
*   **Eccentricity:** The eccentricity of the ellipses, allowing them to be stretched in the Y-direction (or any direction).
*   **Number of Struts:** The number of struts or steps around the ellipse, affecting the density of the lines.
*   **Sides:** The number of sides used to approximate cylinders in the structure.
*   **Base:** I'd like to have optional base and top rings to clean up the edges of the ruled surface. These should have:
    *   **Base Height:** The height of the bottom base ring.
    *   **Base Width:** The width of the bottom base ring.
    *   **Top Height:** The height of the top base ring.
    *   **Top Width:** The width of the top base ring.
    *  **Offset:** An offset to control how far the hyperboloid extends into the base rings.

It would be very helpful if the base rings were created using differences of cylinders to provide a clean way to generate the rings. I’d like to have all these parameters modifiable via variables at the top of the OpenSCAD file.

Could you please create the necessary OpenSCAD code to achieve this? I think it'd be best to start from scratch, and I'd like you to generate all the files, including the main one which will call any libraries. I do not think any libraries are needed.

Thanks!

Hey! I'm looking to design a custom keyring, and I've got a pretty good idea of what I want, but I need some help with the OpenSCAD code.

I'd like the keyring to have an oval shape, sort of like a squashed sphere. I want to be able to control the overall size, especially its width and height. Also, it should have a hole for attaching to keys, which I'd want to be able to easily adjust for position and diameter.

The main thing I'm after, though, is adding text vertically on the surface of the keyring. I need to be able to specify the text, the font, the size of the letters, and the spacing between letters. I’d like the text to be centered along the oval shape. I need it to use the `write` function from the `Write.scad` library.

I'd also like to control the thickness of the font.

Also, while this version won't be using an image, I may want to add one in the future. Could the code be flexible enough so I can do that later? Maybe with an option to load an image and wrap it around the keyring’s surface?

Could you create a parametric OpenSCAD file for this?

I'd like to create a customizable oval-shaped keyring with text on it, and I'll need a parametric OpenSCAD file for this.

Here are the specific features I'm looking for:

**Shape:** The base of the keyring should be an oval shape, formed by a stretched sphere. I want to control the overall scale of this oval. I also want control over the stretching along each of the x, y and z dimensions.

**Hole:** I need a circular hole at the top of the oval for the keyring. The diameter and position of this hole should be adjustable.

**Text:** I'd like to add text to the keyring. This text should be customizable, including:
    *   The actual text itself
    *   Font selection (I'd like to use the Write.scad library for this and have access to font options like "orbitron", "BlackRose", and "braille")
    *   Text size (height of the letters)
    *   Text thickness
    *   Spacing between letters
    *   The position of the text along the x and z axis.  Specifically, I need the text to be rendered along the z axis such that it is flat on the side of the oval. And I need control over its position to be able to move it along the x axis. I need a parameter to control the offset of text along the z-axis from the front of the oval.
    *  The ability to center the text in the given space.

I'd like to be able to turn the text on or off with a simple variable, as well as control the color of the text.

Could you provide a parametric OpenSCAD file that allows me to adjust these parameters? I'll be using `Write.scad` for font rendering.

I'd like to design a golf tee with some text wrapped around it. The text should extrude out from the tee's surface. I'd like the design to be parametric so I can adjust the size and the text easily.

Specifically, the golf tee itself will have a standard shape, with a thin cylindrical base, a wider, conical section in the middle, and then a narrower, tapered section at the top. I'd like to be able to set the overall height and diameter of the tee.

The text will be placed around the middle of the tee, and it should extrude outwards from the main body of the tee. I want to be able to control the text, the font, size and the thickness of the extrusion, as well as control the spacing between the letters. I'd like to have a selection of fonts available, like 'Knewave', 'Letters', 'Orbitron', 'BlackRose' and 'Braille'.

I need to use the `write/Write.scad` library to handle the text extrusion.

I'd like a customizable bottle design, similar to the one I saw on SKS Bottle's website. I'm hoping to be able to adjust a few key parameters:

*   **Resolution:** The overall smoothness/detail level of the bottle's curves. I'd like to be able to pick between 12, 24, 36, 48, or 96 facets for the curves.

*   **Sides:** The number of sides for the bottle, influencing if it's more of a cylinder or a polygon, let's go with a range of 3, 4, 5, 6, 7, 8, 12, 24, and 48 sides as options. I'd like to have a "Round" option for this as well which would probably translate into a very high number of sides for rendering purposes.

*   **Total Bottle Height:** The total height of the bottle, adjustable from 20mm to 320mm.

*   **Shoulder Roundedness:** The radius of the rounding at the bottle's shoulder. I'm thinking values between 3 and 30 mm would work well.

*   **Bottle Width:** The overall diameter of the bottle itself, ranging from 35mm to 120mm.

*   **Bottom Weight:** This would allow us to adjust the bottom diameter of the bottle. Positive values should increase the bottom width relative to the rest of the bottle, and negative values should narrow it, adjustable from -30mm to 30mm.

*   **Rounded Bottom Radius:** The radius of the curve on the bottom of the bottle, between 0.1mm to 15mm.

*   **Neck Height:** The height of the neck section of the bottle, probably adjustable from 19mm to 40mm.

*   **Opening Diameter:** The inside diameter of the bottle's opening, adjustable from 16mm to 70mm. This needs to be less than the bottle width.

*  **Threads:** This defines the neck finish. I'd like the option for 4 and 9 (corresponding to 415) as options - if you could add some comments as to the meaning of each number that would be helpful.

*   **Oblong Proportions:** Let's try an "ooblong weight" parameter for squishing the bottle into an oval. It should range from 0 to 10, with 0 being a perfect circle.

*   **Cap:** A simple on/off option for including a matching cap.

I'd like this as a single .scad file if possible and I'd also like for the threads to be based on the module for screw threads from the provided .scad, I don't want to import other libraries if I can avoid it.

Hey! So, I'm looking to make a traffic cone shaped birthday cake holder, and I want to be able to customize it easily. I've got some basic parameters in mind, like the size of the base, the cone's height and its top and base diameters, and the wall thickness of the cone itself. Basically, it's a flat square base with a hollow traffic cone on top. The cone part should be hollow to fit a birthday candle in the center.

I'm hoping you can generate an OpenSCAD file for me that will create this object. It should be parametric, so I can easily change these values and re-render. Specifically, I want variables for:

*   `base_size`: the size of the square base
*   `cone_base_size`: the diameter of the cone at its base
*   `cone_top_size`: the diameter of the cone at the top
*   `cone_height`: the height of the cone
*   `wall_thickness`: the thickness of the cone walls and the base

I also need the final object to be a single solid object (not separate parts).

I don't have a preference on libraries to use, but I figure you might find some useful functions in the BOSL2 library.

Let me know if you need anything else from me.

[Assistant]
traffic_cone_bday_cake.scad:
```
$fn=200;
base_size=16;
cone_base_size=15;
cone_top_size=7;
cone_height=20;
wall_thickness=1.2;

difference() {
	union() {
		translate([-base_size/2,-base_size/2,0]) cube([base_size,base_size,wall_thickness]);
		cylinder(r1=cone_base_size/2,r2=cone_top_size/2, h=cone_height);
	}
	translate([0,0,-0.01]) cylinder(r1=cone_base_size/2-wall_thickness,r2=cone_top_size/2-wall_thickness, h=cone_height+0.02);
}

Hey, I'm looking to get a custom battery box designed for 3D printing using OpenSCAD. I've got some specific requirements, and I'd like it to be parametric so I can easily adjust things later.

Essentially, I need a battery holder for AA batteries, and the key thing is that I want to be able to specify how many cells it holds. It should have screw mounting points, a way to run the output wires, and little cutouts to aid battery removal. I'd like the battery compartments to be oriented in a row, like cells in a standard AA battery holder.

Here are the basic requirements and some desired features:

**Parametric Design:**
*   **`cell_count`**:  The number of AA batteries the holder should accommodate. This should be a primary parameter controlling the length of the holder.

**Physical Layout:**
*   **Battery Compartments:** Cylindrical depressions to hold the batteries, with a bit of extra space for easy insertion/removal. Spacing to match the size of AA batteries.
*   **Spring Contacts:** Cutouts for the typical spring contacts at the positive terminals of the batteries.
*   **Solder Flanges:** Cutouts where the battery terminals on the box would be soldered to wires.
*   **Mounting Points:** Screw mounting points using cylindrical standoffs with counterbored mounting holes. The mounting points should be on the sides of the battery box.
*   **Output Wires:** A channel/cutout to run output wires from either end of the battery holder.
*   **Polarity Markings:**  Simple plus and minus markings near each battery contact and bottom terminal.
*   **Battery Removal:**  A cutout at the top edge of the battery box to allow for an easier time removing batteries.
*   **Rounded Edges:** Slightly rounded edges, as much as is reasonable, on all edges of the box and other features.

**Additional Notes:**
*   I am not concerned about internal structural supports.
*   I don't have a specific thickness in mind for the box walls and features, so you can make them reasonable for 3D printing.
*   I would like the overall dimensions to be reasonable for a project using a small to medium-sized robot, but I don't have specific dimensions to provide - I'm happy to provide that feedback.

I think those are the core things. I'm looking for a complete OpenSCAD file that can generate the whole model, and I'd like to avoid using any external libraries if possible (for ease of use). Can you create this?

I'd like to create a design with two main modules, both similar but with some differences.

Module 1 should be a linear extrusion of a 2D shape, with a height of 8, and color `[1,0.3058823529411765,0.9176470588235294]`. The 2D shape is a polygon with the following points and paths:
```
points = [
[-5.05,6.45]
,[-4.05,7.45]
,[3.95,7.45]
,[4.95,6.45]
,[4.95,-6.55]
,[3.95,-7.55]
,[-4.05,-7.55]
,[-5.05,-6.55]
,[-3.05,6.45]
,[-4.05,5.45]
,[-4.05,-5.55]
,[-3.05,-6.55]
,[2.95,-6.55]
,[3.95,-5.55]
,[3.95,5.45]
,[2.95,6.45]
]
paths = [
[0,1,2,3,4,5,6,7],[8,9,10,11,12,13,14,15]]
```
Module 2 is also a linear extrusion, but with a height of 5 and color `[0.2,0,0.4]`. Its 2D shape is a polygon with these points and paths:
```
points = [
[-4.50,5.85]
,[-3.40,6.85]
,[3.05,6.95]
,[4.25,5.75]
,[4.30,-5.75]
,[3.25,-6.90]
,[-3.45,-6.75]
,[-4.50,-5.70]
]
paths = [
[0,1,2,3,4,5,6,7]]
```

The convexity should be 10, twist should be 0, and the fragment count `$fn` should be 10 for both modules.  Could you please generate the OpenSCAD file(s) for this?

Hey! I've got a design in mind and need your help generating the OpenSCAD code for it. I want to start with a cube, centered, and I'll subtract a sphere from it, also centered. Then, I want to add another shape that's the intersection of a smaller sphere and a slightly smaller cube, also centered. Finally, I want to translate that entire combined shape up on the Z axis and then scale everything up.

Specifically:

*   The main cube should have sides of 3 units.
*   The sphere being subtracted should have a radius of 2 units.
*   The smaller sphere for the intersection should have a radius of 1.3 units.
*   The smaller cube for the intersection should have sides of 2.1 units.
*   The whole design should be translated +1.5 units on the Z-axis.
*   The final result should be scaled by 10.

Can you create the OpenSCAD code for that? I don't need any fancy libraries for this, I think it can all be done with the built-in primitives. Let me know if you have any questions!

[Assistant]
test_thingi.scad:
```
function main() {
   return union(
      difference(
         cube({size: 3, center: true}),
         sphere({r:2, center: true})
      ),
      intersection(
          sphere({r: 1.3, center: true}),
          cube({size: 2.1, center: true})
      )
   ).translate([0,0,1.5]).scale(10);
}

```
