Vibration damper, for noise reduction

thingiverse

This device minimizes background noise by preventing vibrations from being transmitted to the worktable, which would otherwise amplify them. It's a good idea to set the brim distance to zero millimeters or install skirts, so that the part securely adheres to the print bed. A damper was introduced for Prusa I3 wood models on July 14th, 2017.
