This is a set of refrigerator magnets featuring the popular online game Portal.
Print the "guy" in black.
Print One portal in blue and one in orange/red.
I used Hot glue to adhere the guy parts to the portal.
I used magnets out of old hard drives hot glued in place. You may not need/want such beefy magnets.
