Dampener spring - Pyramid shape, no supports
Wanted to get some sort of TPU dampener for flat vibrating things for a while. That'll do it.
Can be used with hard drive cases that vibrate a lot.
I recommend to print half of the spikes inverted because otherwise they'll all curl along in the same direction and bend (still will dampen tho).
For a hard drive TPU 95A 6 pieces without mirroring wasn't enough so either make more with mirroring, or use a stronger TPU, but then there's a chance to get vibrations again.
