Micro 4/3 Body Cap Lens using Fujifilm Quicksnap Flash lens with Simple Helicoid by likangning

Ultra-compact ~30 mm toy lens for Micro 4/3, like a 30 mm body cap lens.
This uses the lens from a Fujifilm Quicksnap Flash disposable camera.
The lens is held together using stitches, since I didn't want to require screws for this project and I wasn't confident my printer could print any other fastening system well enough. There's also some black electrical tape on the insides to block out light leaks.
The helicoid itself uses 4 pegs in rails instead of a full screw-and-thread design. The sides of the pegs are about as smooth as any filament-based printer can print, so while this design is fiddly to assemble, it doesn't need as much sanding work as a full screw-and-thread.
