Printrbot Simple Z-Axis Stabilizer and Filament Guide
thingiverse
Most filament guides don't use bearings and don't really work that well, since they're adding too much friction. This thing reduces the z-wobble and guides your filament with close to no friction. Instructions You'll need: 2 x 608 bearings (the skateboard bearings most designs here use) 2 x M3x12 screws (just add nuts to your screws if you only got the M3x16 ones)
