Tevo Tornado squash ball anti vibration feet

My version of the squash balls for the Tevo Tornado.
Improvements:
- no screws, just put them under the original feet and they will stay in place
- more than half of the ball free to swing and damp
- indents on all 4 sides. Place them directly in X/Y direction to allow even more room
- enough space under the printer for tools, but not unstable sametime

V6 is a little bit reinforced.
