Scouts have embarked on a tech-centric mission of goodwill that can literally reach out and grab you.

By now you’ve probably heard about 3-D printing and how it’s making the unimaginable tangible (also affirming for many: Star Trek could indeed predict the future). You may have even read about the Venturers and Scouts who are leading efforts to create 3-D printed hands for children born with partially formed arms.

But do you know how these helping hands, along with the Scouts who create them, are changing the world for kids who are born without limbs?

In a video from Mic, Daisy Rosario reports 1,000 babies a year in the U.S. are born with a missing or partial limb. Before 3-D printing, prosthetics that compensated for limbs were rare and expensive. Expensive enough to inspire a South African carpenter, who had lost fingers in an accident, to collaborate with an innovative prop designer to refine the 3-D printable hand.

Now, Scouts are part of a worldwide group of volunteers who were initially recruited to the cause in a fittingly 21st Century manner (via YouTube comments – check it out in the video). The outcome? Prosthetic hands that would have cost thousands of dollars only to be quickly outgrown by kids who need them now cost less than $50 to make. Through e-Nable, kids can get the prosthetics at no cost.

The Boy Scouts of America has a history of encouraging kids to change the world for the better by exploring careers in science, technology, engineering, and math (STEM) fields. Both STEM activities in existing programs and the pilot STEM Scouts program challenge children to innovate and serve others.
