I've been wanting a door stop on a door for a while and finally decided to design one. Has a serrated tip for carpet (probably won't work on hard floors) and a clip for the arm to snap into when not in use.

Prints in two pieces, they'll be oriented the best way for printing. I used a 6mm nozzle and 0.4mm layer height.

Needs 2x M3 screws (12mm max) to assemble the arm and bracket, and 4x wood screws to mount it to the door.
