Three years ago, Paul McCarthy began searching for an inexpensive yet functional prosthetic hand for his son Leon, who was born without fingers on one of his hands.
After coming across a video online with detailed instructions on how to use a 3D printer to specifically create prosthetic hands, he had a brilliant idea. This dad decided to create a custom hand that would eventually help his son with little things we normally take for granted, like picking up a water bottle or riding a bike.

A normal prosthesis would have cost the family in upwards of $30,000, but Mr. McCarthy says the 3D printed hand cost him $5-$10 to create.
That cheap cost will easily allow the pair to experiment with different designs and change the size of the prosthetic as Leon grows older.
