Quiet Retraction Feeder Dual Bowder Extruder for Ultimaker 1

thingiverse

This project is still under development. It features a second quiet retraction extruder mount for the Ultimaker 1, inspired by http://www.thingiverse.com/thing:53690. The purpose of this design is to minimize vibrations that might cause the Ultimaker case to act as a resonance body. The second version (quiet retraction high) of the mount is reinforced for added strength and leaves more space between the filament roll and extruder. Both designs are compatible with 608z bearings. To create an extruder, you need either 2x quiet_retraction_second_estruder.stl and the middlepiece or 2x quiet_retraction_high.stl and the middlepiece. For the bowden clamp, use http://www.thingiverse.com/thing:17027, and for the large motor gear, use http://www.thingiverse.com/thing:25501. The smaller gear is included with the extruder stl. The vibration absorption provided by this design is impressive; it significantly reduces retraction noise to a minimum. Please share your feedback!
