I have designed 2 sizes of 9.5 mm reels that can be 3D printed. The small one is 80 mm diameter and the larger one is 140mm diameter. They both consist of 2 parts that can be pressed together, no glue needed.
I’ve developped these reels so I can easily transfer the film from a Pathé Baby enclosed reel on to a reel that I can use with my 9,5mm projector/scanner.
