This is my simple project box I use as a template for my gadgets.

Features:

• many parameters, e.g. tolerance, wall thickness, hole sizes
• no overhangs with >45 degree slope
• lid stays firmly in place
• waterproof if you add silicon sealant
• optional pcb+cable mount

The customizer doesn't work as of 2022/10 because Thingiverse's OpenSCAD is too old. Just get a modern OpenSCAD on your own computer instead
