Prusa Z Rod Constraint
thingiverse
Inspired by the Z rod constraints on the Makergear Prusa. You can print 2 or 4 of these and use them to eliminate all Z wobble on your Prusa. I've included some before-and-after photos from cubes but the REAL visual proof will be when I reprint the OH shot glass. BEFORE! http://www.thingiverse.com/image:63205 AFTER! http://www.thingiverse.com/image:63204 SAME GCODE! Instructions Print, stuff with one 608 bearing each. Works OK for 5/16ths too. A C-clamp may help you fit the bearings.
