Bolivian teen Leonardo Viscarra, who grew up without his left hand, has designed and built his own prosthesis using a 3D printer, presenting his remarkable project from the city of Cochabamba on Saturday.
Leonardo, who is 14-years-old, was diagnosed with amniotic band syndrome, a birth defect due to which a baby may be born with stunted fingers, toes, or limbs. His new hand, which he printed at school, is made of thermoplastic works with nylon threads that collect movements from his wrist and transmits them to the prosthetic fingers.
