Lomo Tank Adapter for "Bucket Processing"

thingiverse

This is a light-tight funnel for the Lomo UPB-1A film processing tank, used for processing 16mm and 8mm motion picture film. I’m calling it a “bucket adapter” because it provides an escape route for folks who can’t get the Lomo reels loaded in the dark. They can screw the bucket adapter into the Lomo’s lid and stuff their film inside for “bucket processing.” (Without this adapter, you would need to insert the reels and spindle to make the tank light-tight. But that leaves no place to stuff the film if you're using the bucket method.) NOTE: I wouldn't recommend stuffing a whole 100ft roll of film in there using the bucket method. 50ft is more sane. The top piece is a raised disc with a pocket for a nylon bolt that attaches to the drain on the bottom. The drain has a labyrinth so the chemistry can pass through but the light should be blocked. This part still needs some testing to make sure it doesn’t fog film, but I’m hoping it will help relieve Lomo anxiety, especially for beginners!
