3d TOUCH PRINTER SUSPENSION

Hi there,
I have my big 3D touch printer on my desk at work and the vibration from the machine was driving me crazy and the noise transmitted through the desk.
So I did come across people putting squash balls as feet on their makerbots so
I adapted the idea for my 3D printer.
The feet are simply tubes that fit snuggly in the aluminium feet.
then I fitted some doggy tennis balls (I think they are the same as the squash balls in diametre)

Anyway the noise has decrease and i have no more v
