I really hated the key holder I had next to my door, so I created this in an evening using magical elements called "mag-nets!"

It works like a charm and can accommodate at least three sets of keys, I haven't attempted to put more than that up there.

Print out the two pieces and insert magnets into the holes. You'll probably want to glue them in (I did) and then glue the lid to the base.

I attached this to the wall with double sided foam used for mounting pictures, but I've provided the Autodesk 123D Design file if you'd like to play with it more.
