13-year-old turns school 3D printer into business for epilepsy awareness

When Andy Barrett looked at his school’s 3D printer, the 13-year-old did not see just another classroom machine. He saw a way to build a business that could help people.

The eighth-grader at Granville Middle School in Ohio designed, printed and sold about 150 custom fidget toys to students, teachers and neighbors. Rather than spend the money on himself, Andy directed every cent of his profits to epilepsy awareness and research.

The project began in a technology and engineering class. Andy saw that his classmates were interested in fidget toys, which can help people focus, manage stress or keep their hands occupied. He decided to create his own designs, customize them and sell them directly within his community.

After receiving approval from his teachers, Andy learned the design software and tested different shapes, hinges and textures. The work involved clogged nozzles, peeling plastic and failed prints, followed by hand-finishing to remove excess material and smooth rough edges. Friends tested early versions, and Andy adjusted the designs until the toys became sturdy and comfortable to use.

Interest spread through the school, turning occasional sales into a steady stream of orders. Andy began tracking customers and money while fitting the work around his classes. Reaching 150 sales gave him a functioning business built from his school laboratory, with its profits supporting epilepsy awareness and research.
