Anti-slip rubber feet on my ETA Crystela Digi kettle were very worn out and it kept sliding on the kitchen top. I designed this model as a copy of the original feet. It fits perfectly and provides good anti-slip effect.

This should be printed from TPU. The softer the used TPU, the better will be the anti-slip effect.

I used 3DJake TPU 95A and it works quite well.
