Vibration eliminator for Geetech Prusa i3 Pro B - Printer Vibration dumpers

My printer was annoyingly noisy, I tried to put something beneath, foams,rubber ... nothing, so I used a rubber rings 12mm diameter and 8 mm height. Designed a simple elements holding rubber rings in place. It works like a suspension and now my printer is much quieter.
Not sure about fast printing but so far ... after first tests it looks promising.
Works with Geeetech i3 Pro B plywood or aluminium or plastic frame up to 5.6mm thick.
Single rubber tube version and double rubber tube for bette
