Lomo Tank Spiral Sleeve

thingiverse

This is a sleeve/bushing to fit the top wheel of a Lomo tank, allowing you to develop a single roll of 16mm without using the secondary/middle spiral. This may have been in the original set of parts that came with the tank, but mine didn't have one so figured I'd mock one up quick. Helped with loading the film since I could feel the film through the top wheel while in complete darkness, so I knew when it was loaded correctly. Possibly works for the same thing with 8mm.
