UM3DPF - universal modular 3d-printable frame generator

What

This generator can be used to create 3D-printable frame structures for all kinds of things, like electronics boxes (perhaps even a frame for a small 3D printer), Mario cubes, etc. :) (You can also create other rectangular cuboids, not just cubes.)

It has a hole pattern all around it in 20mm increments, where you can (create and) attach all kinds of things. One reason to choose a distance of 20mm was that quite a few components that are meant for 20xx (2020, 2040, etc.) aluminum extrusion profiles could either be directly attached or modified to fit with little effort.

A word of warning

First of all, consider this experimental! I've used it to generate a small test frame, and everything works as intended, but it would be a good idea to a) visually check the generated model for sanity and b) print a test piece (ideally a corner, cut in your preferred slicer).

How

1. Download and open the file UM3DPF - universal modular 3d-printable frame.scad in OpenSCAD.
2. Un-hide the customizer.
   
3. Change the customizer settings to your liking.
   
4. Choose if you want a "tank frame" or not (default = regular frame). The regular frame panels are only joined in the corners. The "tank frame" lets you add additional assembly holes. Here, three per side.
   
5. But be careful if you generate a "tank frame" with additional assembly holes! They could collide with the attachment holes!
   

I'm sure there are things that could be solved better or in a more elegant way. Never the less, I hope this comes in handy for someone. :)
