Y-Axis Tensioner

This Y-AxisTensioner is a modification of http://www.thingiverse.com/thing:367760. I modified it to be a direct replacement for the existing bearing mount of my RepRap G3D (Prusa i3 design from Gadgets3D).
I changed the following from the original design:
- width to accommodate a single bearing (instead of 2)
- a recess in the screw plate to keep it in position
- a hole that allows the embedded nut to be pushed out (removed)
- an inset for the bearing bolt nut
