Compliant door stop

Due to its shape it is able do be deformed in such a way that it moves almost like flexible material. This makes it realy gentle on the door but ensures it staying firmly put. The barbs on the lower side provide additional grip, especially on carpet.

PLA works just fine and i had never any issues. PETG and every other material might be fine as well.

I use the one with ridges on the top side for more grip but you might prefer the sleek one without ridges
