About this 3D model

I remixed the original Z axis carriage to add longer arms and an additional set of holes. I also opened up the bearing location by 0.1 mm. Clamps and Bearing Rod Supports are the same as the original design but presented here for convenience. I like the 10mm bearing rods because they add more stiffness to the Z axis carriage. The longer arms and extra mount points further stiffen the Z axis carriage. I suggest that you print the bearing clamp laying down and with supports in the square opening. Update 12-24-2016:I decided to make the bearing clamp more robust, eliminate the countersunk screw hole, and rotate it 90 deg. so it is laying down. Both the original and V2 are posted.
