I wanted larger sizes than available, so I made it so you can have more sizes. 3u is available as STL, other sizes can be made using OpenSCAD. Since it is supposed to be 100% compatible with LeIN's model, you can only adjust the size using the customizer; if you want more control over the attributes you can make changes to the source code.

Label is currently a PrusaSlicer file, because it was quick and easy. I'll update this if I decide to make it an OpenSCAD model.

I recommend that you use it with the top designed by LeIN.
