Super 8mm Film Spindle Adapter
thingiverse
This contraption was cobbled together using Tinkercad. Fiddle with it online https://www.tinkercad.com/things/4mTVylLUolj Not ideal (it sprang to life over Sunday brunch), but it manages to accommodate my ProMaster 8mm film editor. I happened to be without one of the adapter spindles and found that common adapters sometimes tucked away in old films weren't functioning well at all. This invention converts the smaller squared-off spindle on 8mm movie viewers to super 8mm core size. The slot is for the retaining lever to fold over neatly into place. Savor it while you can, as odds are good no one is editing film anymore.
