Nanohex Bumper

A dedicated bumper (props guard) in order to avoid crashing propellers in walls.
Designed with Openjscad.org on my lenovo yoga book.
Tested, works pretty well, doesn't break, at least with my tests involving many crashes on hard ground and walls.
I had to create various prototypes to adjust it correctly and make it solid yet flexible with PLA.

Don't forget to reverse the model upside/down before printing it.
