Scince I got my QR extruder by Bondtech my prints got far more consistent. Also I can print with up to 180mm/s.

The design is published on youmagine. If you want a kit with all parts please write an e-mail to info@s-technologies.eu.

But there is one thing, which I didn´t like. It was the noise. When the extruder retracted the filament it made a loud squeegee noise.

For people, which have their printer in the garage or a other kind of working room this doesn´t matter. But mine is standing in my apartment so this is really annoying.

So I figured out that the hole printer works like a big resonance body.

So how to get rid of this vibrations? Damping is the solution. I had the idea of an rubber ring out of flexible filament which damps all vibrations from the motor.

This is the main idea of my construction. The outer and the inner part of the extruder mount is connected by a two part flexible ring.

For more reliability I used M3 inserts for the threads.

So what do you need:

5 M3 inserts

3 M3x30

2 M3x6

For the installation disconnect the electric plug. Mount the main plate in the position of the original Extruder Use the orignal screw and a nut on the other side.

Mount the outer PLA ring to the main plate. But one of the outer ring stops over the shaft. Place the two flexible ring parts around the extruder gear box and insert the pack in the outer ring. Place the outer ring stop on the other side an screw all together.
