Door cushion

I use this door cushion at the dorms to lower the sound of the doors closing behind. We have those self-closing and self-locking doors everywhere and it's simply impractical to always unlock the kitchen. So the lock is always extended to prevent the doors from locking in. This produces a loud bang every time the doors slam against the frame. This cushion aims to solve that problem and through my testing I'd say it's very successful at that.

The one in pictures has been in continuous use for 9 months. You can see the wear and tear on it but it's still fully functional. I suggest doing 4 layer walls and above 10% hexagonal infill if you print this out yourself.
