Watch This 5-Year-Old Throw Out the First Pitch Thanks to a 3D-Printed Hand

This heartwarming video shows 5-year-old Hailey Dawson throwing out the first pitch at Camden Yards before a baseball game where the Orioles beat the Oakland Athletics 4-2.

The hand was produced by a 3D printer and designed by engineering students at the University of Nevada Las Vegas.  The hand is operated by wrist movement — when Dawson bends her wrist to a down motion, the fingers grasp. When she raises her wrist, the fingers release. Simple, but effective.

Dawson was born with Poland syndrome, which means that her pinky and thumb are undersized, and her middle three fingers aren’t useful.

The files to create the hand, called Robohand, are open source and free — so with your own 3D printer, you can create your own.
