110 Film Cartridge V2

This is a reusable 110 film cartridge. My original design is for a "fast" film speed, but I have added a "slow" speed cartridge too. You can cut 35mm film into 110 by cutting it in half (in the dark, carefully). Various people on Etsy sell 35mm to 110 splitters, or you can make your own. 

I would add some flocking tape to the entrance of each spool for extra light protection. I would also fully tape the seam in gaffer tape or black duck tape to keep the light out.

I made this so my wife can shoot her Minolta Zoom 110 SLR with cut down 35mm film, and so I can develop the film at home. There is a notch in the lid so the Zoom110 SLR will work with unperforated film.

Print in black filament. You may want to increase your extrusion multiplier to make sure it's light tight. I printed this in green to make it easier to see a photograph.

Changes for v2:

Simplified lid design so it prints without small features that can cause gaps when printed. 

Thickened outer rim of lid to make it stronger and more light tight. 

Refined spool design and gear teeth.

The base cartridge is unchanged, so print the old version with the new lid and spool if you want a slow cartridge.
