My adaptation of this Z axis. I made a few minor tweaks to some of the parts to fit my SmartCore. I removed the 'extra' belt mounts on the front of the bed carriers. This makes them dedicated to the left or right side, but I think it looks better.
I also remixed the left bottom corner holding the motor. The remix can be found here: http://www.thingiverse.com/thing:1327913
Thanks AndreasL for this great improvement of the original SmartrapCore!
