FT-6 Vibration Dampening Kit

I noted the X axis belts tend to vibrate a lot which has caused variation/texture on surfaces of printed items.

Part of the problem came from the idler bearings on the x axis were not perpendicular due to unbalanced forces of the belt. So the belt was riding the lip on the pulley and causing a vibration. So I made jig to pull the idler perpendicular.

The second part of the problem came from the belt vibrating just due to its natural frequency. So I made a tab that dampens the vibration.
