Since the 1940s, many companies around the world have created small three dimensional plastic puzzles known as "keychain puzzles". These puzzles usually consisted of around six puzzle pieces, and when correctly assembled, created a keychain figurine. I've reproduced three of my favorite keychain puzzles from my youth; the dog, the giraffe (ok, maybe my wife's favorite as well, sigh) and the elephant. And if you wish to customize these puzzles I've also included the Autodesk Fusion 360 CAD files for each.
