Albert Manero said he was stuck in traffic listening to the radio when he heard an interview with a man who built 3-D-printed mechanical hands.

Alex Pring was born with one arm. His other extends to his forearm and stops. As he started growing up and going to school, he had some questions about his limb difference.

Alex Pring’s story first made the news when he was a little boy. Pring's mother wanted to find a prosthetic for her son who was born missing most of his right arm. With the help of some student engineers at the University of Central Florida, he was gifted a 3D-printed one for free in 2014.
