13-Year-Old Turns School 3D Printer Into Fidget Toy Business for Epilepsy

A Middle School Tech Lab Becomes a Factory

Most eighth-graders see their school's 3D printer as a tool for class projects. Andy Barrett saw it as a business. The Granville Middle School student in Ohio started designing and printing fidget toys on the school's equipment, sold roughly 150 of them, and donated all the proceeds to epilepsy awareness.

The story is not just about a kid making money. It is about a school 3D printer doing exactly what advocates have promised for years: giving someone the tools to turn an idea into a physical product without leaving their neighborhood.

The Print:able Challenge Connection

Barrett's project was part of the Make:able Challenge, a global competition organized by PrintLab and Autodesk. This year's edition drew 1,200 students from 16 countries. The challenge asks participants to design and 3D print an assistive device for someone with a disability or daily challenge.

Barrett did not just build a fidget toy for the sake of it. He designed the toy for a specific person: a St. Louis woman who needed a way to keep her hands occupied independently. The device lets her eat chips without assistance. That is a small but genuine improvement in daily autonomy, and it is the kind of outcome the competition was built to encourage.

What It Actually Takes to Run a Print Business From School

Printing 150 fidget toys is not trivial on a school machine. It means managing print queues, dealing with failed layers, and keeping the filament path clear between classes. Barrett had to work within the constraints of shared equipment and school schedules. He also had to handle the sales side: pricing, orders, and delivery to classmates and neighbors.

The financial result was modest. Fidget toys sell for a few dollars each. The total revenue was not life-changing, but the donation to epilepsy awareness made the project visible in a way that school assignments usually are not. Barrett got local press coverage and a feature in the Times of India, which is unusual for a middle school 3D printing project.

What This Says About 3D Printing in Schools

Barrett's story is a useful counterpoint to the narrative that 3D printing is only for engineers or industrial users. A school lab, a free design tool, and a student with time on his hands are enough to produce something useful. The Make:able Challenge framework gives that effort structure and a real-world audience.

The assistive device angle is also worth noting. Most 3D printing coverage focuses on printers themselves: faster speeds, bigger build volumes, new materials. Barrett's project flips that. The printer is just the means. The output is independence for someone who did not have it before.

Whether Barrett keeps printing after the competition ends is an open question. He has already seen what the process looks like from design through delivery. That is more experience than most adults get with additive manufacturing, and it came from a machine most students only use once a semester.
