20W 3D-printed flashlight

A custom 3D printed flashlight with a mount that I designed for fun.

It's as of yet untested, so print at your own risk.

Thermals have been simulated and should be within spec, but once again, do at your own risk.

To build you'll need the parts below, the printed body of the flashlight, and some M3 and M4 hardware, and some thermal paste.
