I designed this key holder for the printables contest "Models with Magnets":
https://www.printables.com/contest/381-models-with-magnets
This key-shaped holder uses 3 magnets (Ø10mm) to hold your keys
The length of the magnets can be up to 12mm
You can mount the holder to your wall by using two flat head screws (no screws will be visible) or simply use some double-sided tape
