Spool Rollers for Printrbot Simple Tower

thingiverse

The parts securely attach to the tower's bearings on the Printrbot Simple; they suit spools ranging from 65mm to 90mm in width. Although it may seem that the long rollers are sagging, they are extremely rigid due to the tower piece's design. The maximum load per roller is only 0.6kg at most. A bench vise is ideal for pressing the bearings in place, and parts print well with PLA material.
