An excellent resource for 3D models is Thingiverse. Here modelers have shared thousands of free 3D models for use, many of which can be printed on 3D printers. Recently, I found several models of dinosaur skeleton puzzles including a Velocirapter. Normally these puzzles are made of wood, but printing in dark grey PLA (polylactic acid or polylactide) yields a model just as terrifying as the real thing!
