I leave my doors open pretty often and I would rather they don't slam open/shut in the wind. Easy to print and works with 10mm x 3mm magnets commonly found on Amazon. Magnet holes are 1mm deeper than the magnet itself to avoid chipping on the metal. Recommend you glue the magnets into the slots using E6000. This printed without supports using ABS on my BambuLab X1C.
I made two different versions - one with countersunk screw holes for pan head screws, and another that works with double-sided tape.
