Super 8 Film spool/reel holder - Halter/Dorn fuer Super 8 Filmrollen

Fits a Super 8 Reel very tight. Inside is prepared for a 4mm metal pole (e.g. Fischertechnik axis).
An additional 3mm hole at the side could be used to block the reel from slipping of the notch. But as I said, mine printed fine in ABS (2% extra).
