127 film spool
by Hein, published
Spool for 127 film. This is a nearly obsolete film format, film in this size is hard to come by. It is possible to cut down 120 film to 127 size or to buy a bulk roll of 46 mm film and backing paper. Still, you need a spool to wind the film on. If you don't have old spools (or the slightly-too-wide plastic spools made by Efke jam in your baby Rolleiflex), this 3d model might help you.
This is the first 3d model I ever made. Not tested yet. Comments welcome!
