This is version 2.0 of another flashlight, https://www.thingiverse.com/thing:2581075
UPDATE: a newer version of this, with a copper pipe heatsink, is here: https://www.thingiverse.com/thing:2957437
The problem with the previous one was that while it was easy to assemble, electrical connections were difficult to make internally and finnicky. When biking with the light, it would flicker due to vibrations of the bike.
The new version has internal structures to support a 1.6mm / 14 awg diameter solid copper wire, commonly found in household mains wiring. The connection method is much more sturdy. See pictures for the wire bending.
Non-printed Ingredients:
1 protected 18650 cell
1 LED flashlight "drop-in", 26.5mm version. You can buy them from aliexpress, the ultrafire.com site, dealsextreme, etc etc. You want the ones with a reflector and a driver board already built in.
