Printable vibration dampers

This is old, but I thought I'd publish it here as well.

Print 2pcs of "Vibration damper 4mm.stl", get 1 piece of rubber O-ring 25x3mm and superglue it in between the plastic flanges. The O-rings you can get from your local hydraulic maintenance shop and should cost you less than an euro. I used round ones, but flat could probably hold better, because it would have more contact with the glue.
To ease with assembly, I have included a printable file with hole dimensions corresponding to Nema 17
