Spring vibration Isolator

I moved to a new home and the floor is shaky. The printer would shake when walking around in my lab. I designed these to help stop that. They do not remove all of it but it is much better with the 16 X 16 X 2 inch concrete paver.

These can be used for isolating Sub woofers from the floor and many other uses.

They can take up to 9 springs. 3 each was enough to support the concrete and printer.

I got the springs at amazon. They are the same yellow springs used for bed leveling.
