Unable to find a prosthetic hand that fit him him properly, Leonardo Viscarra, a 14-year-old boy from Bolivia, decided to build one himself, using 3D-printing technology.
Leonardo was born with an undeveloped left hand. As a fetus in his mother’s womb, the boy’s right hand was caught in the placenta and unable to develop properly. He was diagnosed with amniotic band syndrome at birth, and could never use his left hand for basic tasks like picking up or grabbing objects. However, an incident during his childhood sparked an interest in assembling and building things, which ultimately helped him achieve his goal of one day gaining almost full use of his undeveloped hand.
