50mm ID Spool centering adapter

This is a thing I made to help center 52 - 60mm spools on the 50mm spool mount from https://www.thingiverse.com/thing:1624641 It will of course work for any 50mm spindle. The parts have a 51mm hole in have a 15 degree ramp. These work great to keep my bowden extruder from making a spool tangle.
