Simplest spool adapter

Simplest spool adapter

Description

Yet another spool adapter, this time specifically for Raiscube 3D printer, but can be useful for other brands as well. The adapter has an ID=24mm and OD=57.5 / 56.8mm for the spools I have. Internal surface is a donuts-like half circle, so it touches the shaft at only one thin line. In fact, spool rotates freely, no more sudden moves, or stuck. The outer surface has a -0.5 deg taper, it is a press fit to the spool. Print & enjoy :)
