World's first working, 3D printed flashlight with plastic circuits

This really was the first functional design I ever made after developing the world's most conductive filament. It also turns out that Functionalize F-Electric is still the only filament available, which is conductive enough to print a nice looking, compact, flashlight out of these files, which we use regularly when walking our dog in the dark, (gotta clean up after her :), or exactly as the keychain flashlight it's meant to be.
