Cone spool holder

My favorite spool holder concept - using it on all my printers.

This remix includes:

1. A mount for a 2020 profile
2. The cone attaches on two 608 bearings, and has a hole for a friction adjustment screw


With two 608 bearings even the 3kg spools will rotate very smoothly. Sometimes, especially with a new spool, too easy rotation may lead to filament escaping the spool and tangling around the 8mm thread rod. Thus the primitive friction adjustment system :) .
