Meet Andy Barrett, 13, who turned school 3D printer into a small business

Most 13-year-olds walk into middle school tech lab thinking about passing their next assignment or making something cool to toss into their backpack. Andy Barrett, an eighth-grader at Granville Middle School in Ohio, saw something entirely different when he looked at his school's 3D printer. He saw an opportunity to build a business that could actually help people. Armed with basic design software, brightly colored plastic filament, and a personal drive to make a difference, Andy launched a micro-business right from his classroom. He designed, printed, and sold roughly 150 custom fidget toys to fellow students, teachers, and neighbours.
