Magnetic Key Box

A box that fits most standard-size keys and that can be magnetically attached to something. Parametric Fusion 360 archive included.

The use case is hiding a spare key outside your house in case you ever end up without your keys or if you need to let someone enter while you're not there.

Just add a pause to insert magnets during printing or use the provided 3mf file.

Magnet diameter is 8mm but you can change this in the parametric design.
