The file '35mm Film Cartridge To 120 Adapter 3D Printer Model' is (stl) file type, size is 199.1KB.
The adapter made by boymeetsmill
did not work in my Mamiya C330. The original design had a solid end rather than holes on both sides.
[Printing Note]: The interior distance of the spool (height of film) is set to exactly 35mm. If your printer is not properly calibrated [like mine], you may have to scale the spool. This distance ended up being ~34.7mm for me; after scaling by 1.013, it ended up being ~35.1mm which worked nicely.
