This is a simple guard or bumper for a corner of a wall. Our dryer door hits the corner and has knocked some paint of already, I didn't want it get worse. I'm surprised that I didn't find anything like this already made. I made it in tinkercad. I just used 3M command strips to stick it on the wall.
I used NinjaFlex for this print, but ABS or PLA would still work.
8% infill to give it the springiness of a soft rubber.
Update: Arranged the part in the orientation that I printed and found it worked the best.
