Description
My printer is upstairs, so the vibration from the printer travels downstairs. To combat this (completely removed the issue) I designed and trialled these.
This will work with a prusa etc, but you'll have to make/design your own mounting piece.
UPDATE: The housings are now a tighter fit to the spring (should still be loose though). and the spring has been increased in pitch.
UPDATE: PLA springs probably aren't the way to go, they lose their springiness over time, and would need to be reprinted.
Thinking some of the problem could be that the orca weighs so much and is almost maxing out the spring with just it's weight. I've uploaded a taller, heavier duty spring that I'll try at some point.

Instructions
Print springs and top piece with support, remove support, put springs on feet of orca. Bolt/Screw/Nail bases down to worktop/wooden board.
Requires 4* bases, 4*springs, and 4*'feet'.
Note that this removes vibration, but will allow the printer to 'wobble' about, this shouldn't affect print quality, as the whole printer is moving, not individual axis's.

Nice Idea, I use a pair of 3 x 11/2 studs and some closed cell foam mat to damp my Orca in relation to the desk and then my downstairs. Might try this though, maybe with some real die springs, not sure I would trust the printed ones for too long :)
I was using vibration mat (2mats, 20mm thick each) only, while this deadened some of the vibration, most was still getting through. With springs, all of the energy is absorbed by the spring, which compresses/flexes, and stops the vibration even getting to the wooden board shown, let alone through to the floorboards.
However, as this energy is transferred to movement by the spring, the printer is able to wobble about on the springs. This does not effect print quality that I've noticed, largely due to the Orca 0.43 having such a solid y-axis.
