120-to-124 Film Adapter
thingiverse
This is an adapter to use 120 film in old 124 film cameras. To successfully use this adapter, you'll need to print four of them out, total. Use two on your current roll of film and then apply the other two on a spare 120 spool - potentially from another roll of 120 film. I highly recommend avoiding rafting if possible since the fit in the camera will be quite tight, so when using rafting, exercise caution to ensure it is fully removed.
