Kansas teen uses 3-D printer to make hand for boy

Mara Rose Williams:

When he was 4 years old, he took apart his mother’s dining room table and gliding ottoman.
Last year, he built a computer, pretty much from scratch.
But it’s what the 16-year-old Louisburg High School junior made about two months ago that has him most excited these days. Not because it was so challenging, but because it’s already changing the life of a family friend’s 9-year-old son who was born without fingers on one hand.
Using a 3-D printer at the Johnson County Library, Wilde made a prosthetic hand that opens and closes and can even hold a pencil.
Just ask young Matthew how he feels about Wilde.
“He’s awesome,” the boy said, thrusting his mechanical hand high above his head.
