About this 3D model

For all information please refer to the original Design "Ultimaker quiet retraction" http://www.thingiverse.com/thing:53690. These are only the changed parts I used. Thank you maxy for the great design. Update 1th Aug 2013: Changed holes to be smaller, because the motor slipped down all to the end of the holes after a while. Even when fastening the screws each print. Sadly I had to move back to the original design from Ultimaker, because the PLA bend too much over time.
