Charlotte and Catherine, students at NuVu and Beaver County Day School, invented an unique prosthetic hand. They called it the Ratchet hand. Each hand can be printed on a 3d printer for about $5; much cheaper than conventional prosthetic hands. 

Yesterday, a reporter from NECN stopped by to shoot a feature about Charlotte's and Catherine's Ratchet Hand. They were joined by Leon and his father. Leon is a 13 year-old boy whose left hand is not fully developed. It is missing all fingers; except for the thumb. Leon has used RoboHands before but was excited to try out the Ratchet Hand. It provides a new set of functionalities; as compared to the standard RoboHand. Leon used the Ratchet Hand to easily draw a picture of a smiley face in front of NECN's rolling cameras.

Leon is excited to continue working with the teens at NuVu and trying out different prosthetic hands; like for example a hand specifically designed to fit into a baseball glove. His father said that it will make playing this sport much more enjoyable for Leon.
