Squash ball vibration dampening for Prusa MK3 or any 3030 frame printer

thingiverse

EDIT 010320: Added V2, support for cup has changed to fill whole area, therefore no need to print supports there. I was thrilled with squash balls and this: https://www.thingiverse.com/thing:2172375 It greatly reduced vibrations that overall sound was very low; I even removed the concrete slab, feeling that it's no longer necessary. The original thing worked perfectly fine, but it was just a bit too high for my taste, so I created a quick and ugly remix that works. You can use different configurations; I tested placing all balls inside the frame, which was too wobbly for my taste, so I moved the rear legs outside of the frame, making it stable again. This should work with any 3030 frame also. Mounting hardware per foot: - M4x12 bolt - Washer - 3030 T-nut or sliding nut; you may find some options here also. Tested with single and two yellow dot balls.
