Utah Teen Spends 300 Hours 3D-Printing Custom Chair for Toddler

Zac Waters, a 13-year-old from Lehi, Utah, turned his summer hobby into a charitable project by creating a custom 3D-printed mobility chair for a 21-month-old child. Inspired by YouTube tutorials, he joined MakeGood, a New Orleans-based nonprofit that supplies free 3D-printed mobility trainers to children with disabilities. Through the organization’s volunteer network, Waters received a match and invested about 300 hours in design, printing, testing and assembly.

The chair includes pink detailing, a detachable cup holder, a tray table, and adjustable foot and head rests, with flexible-material straps for comfort. His grandmother Charlotte Waters provided ongoing encouragement, likening the support to training rails. MakeGood, founded by certified healthcare architect Noam Platt, has delivered over 1,000 such devices and still has hundreds of requests pending.
