door stopper for cats (defined gap)

thingiverse

When our cat enters the room, she opens the door very wide. Which is not wanted to keep the bedroom dark and cool. So I added a small piece with some 6mm magnets to the door (just clip on with some foam tape) and a magnetic counterpart on a arm to the wall. This generates a soft stop of the door at a small gap, wide enough for our cat to enter. The door can still open and close fully. Looks silly, but it works :) Fits all on a 200mm printer bed and prints without support. (Orientate the tip in the holes upwards) Screw all together with M4x30 screws and some nuts, insert 6mm diameter magnets (max. 4mm high) - done Have a good long sleep in on weekends on me!
