Summary

A door stopper that doesn't need any drilling. Just put it against a wall.

It is slightly angled to match the door's angle, and thanks to its custom shape, it can gradually stretch in order to perfectly absorb shocks and preserve the wall and the door.

Designed to be printed with TPU. I'd recommend using only 3 top and bottom layers and 15% honeycomb or grid infill in order to get enough elasticity. But that really depends on your TPU filament brand.
