Kossel Mini XL vibration damper

Printing the first times with my Kossel XL, I found out that there are some pretty noisy low frequency things going on. You did not here that right next to the Printer, but in the next room. So I wanted some very soft vibration dampers, but the Kossel should still stand stable on the table.
These Dampers work and fit really good. Still stable and a lot less noisy.
