3D Printers can be noisy machines, when in use in a close environment it can become particularly annoying.
These handy dampers go in-between your motor and frame, and reduces the noise and vibrations of your machine.
This is achieved by having a 3mm rubber ring in-between two steel plates. This rubber rings absorbs the vibrations and stops them from being amplified by the frame.
One of the flanges has threaded 3mm holes, whilst the other has 3.3mm non-threaded holes.
