CR-10 X-Axis Belt Tensioner for larger bearings

This is a remix/remake of donnyb99's belt tensioner my cr-10 had larger id bearings so I made my own. I had to remake most parts except for the knob. On the puller I added a raised lip for the inner race of the bearings to ride on allowing for smoother operation.

Update: 3/3/2018
added a revised bracket and puller for shorter belts
Update: 3/4/2018
