Boxes.py
A Python based generator for laser cut boxes and other things.
It features both finished parametrized generators as well as a Python API
for writing your own scripts. It features finger and (flat) dovetail joints,
flex cuts, holes and slots for screws and more high level functions.
These are the available generators:
