Uruguayan Manos de Héroes is a foundation which prints hands and arms using 3D technology for people across Uruguay. It has provided more than 100 free prostheses, particularly for those who are economically vulnerable. For Mia Rodríguez, an 11-year-old Uruguayan girl, the first thing she did when putting on her prosthetic hands was drawing a kitten. “Now I can hold the pencil with one hand," says Rodríguez. "Before, I had to do it with both hands because my fist wouldn’t close."
