Ultimaker 2 filament guide

pinshape

This is a custom take on ppyromann's design, with Pully remaining the same but featuring a unique center shaft that fits snugly into the 608 bearing. To assemble it, all you need is a M3x20 screw and an M3 lock nut to secure everything in place. If you're looking for bearings, head over to your local skate shop and ask if they have any spare 606 bearings lying around. Chances are, they'll be happy to hand you a few free "old" ones!
