Anet E12: X belt tensioner

I found out after printing MrCrankyface's that the main part wouldn't allow the slider to reach my belt due to the divider wall (end cap). This design removes that wall and provides a better fit for the E12 X-gantry rail.

Hardware you will need:
2x - reuse rail mounting hardware
1x - reuse roller bearings and hardware
1x - M4x60mm Hex Socket cap screws
2x - M4 Self-Locking Nylon Insert Hex Lock Nuts
2x - M4 washers

1. Press fit the M4 locking nuts into the slider and adjuster knob.
