This is an amazing story. Thanks to Jeremy Simon, who you probably remember from other interesting stories of 3D printed hands, a 10 year old girl named Sierra has assembled a 3D printed Cyborg Beast hand for a Science Fair. Her goal is to show the world how 3D printing can benefit humans and animals. This is just what the world needs, more of... girls like Sierra, and Jeremy Simon.
