Prusa i3 Hephestos noise reduction feet

A Foot for the BQ Prus i3 Hephestos for noisereduction and making sure that it doesnt rock on it's metal frame and the Y-axis' feet.

I also stuck some Foam to the bottom to decrease vibrations on the hollow ikea desk and squeezed some filaflex-scraps to give it a tight fit.

It should fit just fine with PLA without any filing.
