Matthew Shields flashes a smile and high-fives Mason Wilde with the prosthetic on his right hand. Born without fingers on that hand, Matthew, 9, now uses his Robohand to open doors, carry books and catch a ball—thanks to Mason, 17, who made the device with a 3-D printer at the Johnson County Library in Overland Park, Kan.
“It definitely made me proud,” says Mason, a junior at Louisburg (Kan.) High School. Matthew’s mother, Jennifer Shields, noticed last fall that her son’s birth defect was making the third-grader self-conscious and affecting him socially. But even with health insurance, the single mother knew she couldn’t afford a professionally made prosthetic.
Researching online, Jennifer found Robohand, the mechanical hand invented by South African carpenter Richard van As, who lost four fingers in a circular saw accident, and theatrical props maker Ivan Owen, in Bellingham, Wash. The pair posted the free digital design last year on thingiverse.com. “I looked at the plans, but had no idea how to do it,” recalls Jennifer, 43.
Her teenaged son Mason, however, eagerly accepted the challenge. A straight-A student who aspires to be an engineer, he previously had read about three-dimensional printer technology. “I downloaded all the files and spent about three hours scaling the hand to fit Matthew,” Mason says.
