One day I noticed that the humble Propane or LPG gas bottle is pretty much an exact large-scale version of a Lego Mini-fig head. So I decided to cheer up my BBQ bottle with a little Lego lovin'. - so cool :p
I finally got around to building a keychain holder for Amy and I. 3 magnets hold it fairly well. Each keychain brick is held on by two studs. Slopes below mean you can just push on the bottom of the brick to remove.
