Polaroid 110A to 120 film adapters

thingiverse

These adapters help with converting a Polaroid 40 series roll film camera to use 120 film. To use, you'll need a 35mm film rewind knob which will need to be drilled through the bottom of the camera were the negative roll used to be situated. This engages with the adapter with the 11mm inset hole and mounts onto an empty 120 spool. The adapter with the 4mm end (adapter1) mounts onto the other end and sits in the takeup spool end. The single piece dome shape adapter (adapter2) mounts onto the bottom of the full roll of film. A piece of 10mm soft foam is glued between the two remaining pieces and mounted onto the other end of the roll of film and placed into the depressions where the positive roll film used to be situated. A 6x9 or 6x6 film mask should be made so the film won't curl toward the lens and be out of focus. The camera needs to have the light barrier cut through to let the film through, and the edges of the camera need to be sealed with black craft foam to seal out light. The switch also needs taping to keep out light, and a hole drilled into the pressure plate to view the film counter.
