3D printed cylinder showing no backlash

Published 2014-12-24
Cylinder printed with direct Y drive mod on my Solidoodle 2. The light reflects almost perfectly uniformly off the cylinder as I rotate it, showing that both the flat and the pointy bits caused by the belt drive backlash are gone (Yea! Huzza!).
