Quiet Retraction Feeder Dual Bowder Extruder for Ultimaker 1

This is a work in progress.

This is a second quiet retraction extruder mount for the Ultimaker 1. It is inspired by http://www.thingiverse.com/thing:53690. The idea is absorb the motor vibrations so that the Ultimaker case does not act as a rosonance body. It is planned to have the second extruder a little higher, so there is space for the filament rolls and also that the filament clamp is accessible.

The second version (quiet retraction high) of the mount is reinforced, in case you want
