Fully printed bearing spool holder

This spool holder was designed for a 2kg spool of 300x80mm.
My previous spool holder wasn't smooth enough, and couldn't handle the weight.

All parts were designed for 0.2mm layer height, and for a 0.4mm nozzle.
The bearing is a multi-body .stl and contains the 3 parts that comprise the housing for the rollers.
You need to print 23 rollers for the bearing, or 46 in total.

This design is very demanding of your printer. There is no clearance between the non-moving parts, and the rollers on
