Very great thanks to ggenter to inspire me with his "Synology DS216PLAY Vibration Damper". I used it to dampen my Prusa i3 MK2 but i recognized quickly that the unsymmetrical weight distribution of the printer was not compatible with the one kind of damper.

Because the printer is heavier in the back we need stiffer springs there and some softer in the front. Furthermore we have to consider that the power distribution unit on the back right side is the heaviest corner.

In order to that i reworked the damper and made it to a parametrical model with variable wall thickness.

By trying out different settings I am now by the following distribution:

Front: 1,1mm Spring
Back right: 1,2mm
Back left: 1,1mm

I have noticed that the spring got squeezed after a time in fact of permament weight support. If thats the case just replace the concernong spring with one a step stiffer.

Hope you like it. In my case it killed noisy vibrations almost absolutly. I now only hear the fan.
