I was so happy with squash balls and this: https://www.thingiverse.com/thing:2172375
It dampend so much vibrations that overall sound was very low, i even did take concrete slab away, i feel that no need for that anymore.
Original thing worked fine, it was just a bit too high for my taste, so i made quick and ugly remix, it works :)
You can use different configurations, i tested that all balls was placed to inside of frame, it was too wobbly for my taste, so i moved rear legs to outside of frame and now it is stable again.
This should work any 3030 frame also.
Mounting hardware per feet:
- M4x12 bolt
- 3030 T-nut or sliding nut, you may find some thing here also.
Tested with single and two yellow dot balls.
I did print it with 0.15mm resolution, 5 perimeters, 5/5 layers, in position as shown in stl, used supports only from build plate.
You may play with settings and rotate model.
