I made a Maker Faire Robot charm/keychain on a modular magnetic system that is compatible with my other charm designs (ex. Superintendent, Blue Team, etc..). I also included measurements for the face piece if you want to make a custom one, all I ask is to credit me in some way.

Things you will need: 1" diameter key ring, 6x2mm magnets, Super glue
