120-to-124 Film Adapter
thingiverse
124 film was discontinued in 1961. This is an adapter to use 120 film in 124 film cameras. To use this, print four of these adapters. You'll use two on your spool of film and two on a spare empty 120 spool (maybe a used spool from another film). _Note: You'll need to figure out how many turns to wind per picture since the numbers from the 120 film will not show because this is different size. I've found it's about 2.5 turns._
