As soon as your friends find out you have a 3D printer everyone starts putting in request. One friend in particular asked for a Mr. Handy Key chain. I pulled the model from Fallout 3 and tried to print full 3d but quickly found out those tiny little legs snap off in an instant. So I cut it in half and put it on a base.
Update: It was pointed out the base is a bit phallic so I added a square version.
