This is a tiny 120 pinhole camera that I designed for a photographic school. The camera is entirely 3D printed, and everything clicks together with compliant clips and locks with the exception of the shutter blade which pivots on a length of filament. The lens itself can be made from a piece of aluminium or brass foil with a tiny pinhole in the center. The design also incorporates a threaded tripod mount and a sliding window to view what film frame you are on.
