I designed this for the purpose of having something I can quickly print that uses little plastic, but, demonstrates 3D printing. I can print these in about 6 minutes and give them away. It's a simple Smiley Face FOB with its tongue sticking out. NOTE: I realized that the circular tab at the top wasn't flush with the bottom - that's been fixed.Smile2F.stl is the one you want. The other is just there for posterity Print Give away Print again.
