Duplicator i3 belt & chain relief

I noticed my belt was being shaved by my printer bearing blocks and decided to use bearings instead of cutting the blocks which would void my warranty. Using Traxxas standard bearings 5x11x4mm I made the bracket to where it barely pushes the belt out of the way, but does the job. I had seen a x axis chain relief part before an so I thought I add one.

NOTE: this limits your printer on the x axis to about 7.4 inches instead of 8 because the bearing will hit the wall and cause the belt to slip.
