i3 8mm Leadscrew upgrade Z Axis motor mounts for 42mm high motors

Update 8/14/2016

I'm not using a top bearing for the leadscrews (right now), so I removed that bit to make the upper shaft holders quicker to print. I widened the smooth rod hole by .3mm and added a strain relief gap as in the motor mounts.

I also added the missing anti-backlash nut recess on the right X-end piece and again widened the smooth rod holes by .3 mm

Initial Summary

I purchased these Z Axis motors with integrated 8mm Leadscrew - http://www.ebay.com/itm/142038182961, but the motors are 42mm high vs the 47mm of the original motors, so I increased the thickness of the mounts so I wouldn't have to re-drill the mounting holes on my frame.

Also, the smooth rod hole was a little small on the original, so I widened it by .1mm and added an expansion cutout.
