Filament roller guide for Anet A8

I hung all my filament on the side of the cabinet that my printer is on (https://www.thingiverse.com/thing:2775181) so I needed a low resistance guide to steer my filament up and over the top of my printer and back down to the extruder. I quickly drew this up and it's not pretty but it works GREAT. It uses two 608zz bearings, one to swivel and the other as a roller for the filament. I used a 16mm long piece of m8 threaded rod to hold the bearing and screw the two halfs of the roller together.
