The story below follows a 13-year-old named Zac Waters who spent a summer using 3D printing to build a custom wheelchair for a 21-month-old girl, showing how youthful curiosity, accessible design, and open-source thinking can deliver practical, life-changing results.
Thirteen is an awkward, energetic age for many kids, yet Zac Waters focused that energy into something rare and useful. He learned from online resources about 3D printing, joined the design community, and set his sights on a problem that matters: mobility for a toddler with disabilities. Instead of treating the hobby as just a pastime, he applied real-world problem solving and produced a functioning device.
MakeGoodNOLA, a nonprofit design lab, had already made headway by creating the world’s first fully 3D-printed pediatric wheelchair and choosing to give its designs away rather than lock them behind patents. That choice matters because pediatric wheelchairs often cost thousands of dollars and require replacement as a child grows. By sharing designs freely, community-minded builders and families with access to printers can adapt, repair, and recreate devices affordably.
Waters had a home 3D printer and the curiosity to learn more from makers online, and MakeGoodNOLA’s open approach gave him the template and inspiration to attempt a full-scale, kid-sized project. He didn’t stop at replicating a design; he adapted it to meet the specific needs of the child in question. The chair was made in the girl’s favorite color and included functional upgrades like a tray table and a removable cupholder.
While some 13-year-old boys spend their summer playing sports or swimming at pools, Zac Waters spent his time designing a 3D printed custom wheelchair for a 21-month old girl.
After watching a YouTube channel about 3D printing, Waters felt inspired to make a difference using his passion of 3D printing.
The technical details mattered to him: the wheelchair’s footrest and headrest are adjustable and designed to expand as the child grows, which helps delay the need for a costly replacement. Waters also accounted for medical equipment by strengthening the chair’s back to carry heavier loads when needed. Those practical touches are the difference between a novelty and a genuinely useful assistive device.
Waters dedicated his summer to designing, 3D printing, testing, and assembling a custom wheelchair for a young girl. His favorite part of 3D printing is putting the pieces together, and this chair was no exception. The project took roughly 300 hours.
Commitment like 300 hours of work shows how makerspace culture can translate into sustained projects rather than weekend experiments. The build process—design iterations, test fitting, and assembly—teaches critical thinking in a hands-on way, and it produces something tangible that improves someone’s life. That combination of skill development and social impact is what modern STEM outreach hopes to deliver.
Open-source design in assistive technology opens doors beyond one-off charity builds. When labs and volunteers share plans and educate others on how to use them, communities gain the capacity to support more children and adults who need affordable solutions. It also lowers barriers for tinkerers and students who don’t come from wealthy backgrounds but want to contribute practical fixes.
The result here is a kid-sized wheelchair that costs far less than commercial pediatric models and can evolve as the child grows. For families facing repeated purchases because of growth spurts, adaptable printed parts and modular design are real financial relief. That practical framing is what makes community-driven design relevant beyond feel-good headlines.
Stories like Zac’s highlight the power of youthful initiative combined with shared resources and mentorship. They also show how modest tools—a consumer 3D printer, online tutorials, and a generous nonprofit blueprint—can add up to meaningful change. If more kids and communities had access to the same guidance, the number of custom, low-cost assistive devices in circulation could grow quickly.
Hands-on tinkering and open design are not a panacea, but they are workable, scalable parts of a broader solution for assistive technology. The combination of empathy, skill-building, and free designs means that motivated people can turn curiosity into concrete help. That’s the kind of practical civic effort that makes a measurable difference in individual lives and local communities.
