>>3811398I 3d printed adapter for the 35mm canister and used a regular 120 spool for the take-up. I traced out the 35mm film across the focusing screen and cut it out of paper for framing. The rz will auto count once you have some film loaded but you end up wasting a bunch before hand because of the 120 backing paper. I just set it to multi exposure, took a frame, until it got to frame one then it was fine. There was some overlap in the first couple frames though. With the bulk I plan on cutting the exact length and securing it to a used 120 roll, that way there will be no waste and I can take out the film after instead of in a dark bag.
