Prosthesis

Holden Mora shows his new hand, and a pumpkin spice cookie.

Seven-year-old Holden Mora's hand is something that Iron Man might envy. It's bright red, and appears indestructible. Holden was born with something called Symbrachydactyly, and his hand didn't develop properly in the womb.

The 3D hand was created specially for Holden by a UNC  biomedical engineering student, Jeffrey Powell. Powell didn't use high-tech prosthetic engineering tools to create the hand. He used a 3D printer.
