The challenge
A big idea.
Built one print
at a time.
Brock is 15, smart, a lot of fun, and always up for a challenge. He has Duchenne muscular dystrophy, and he brings his curiosity and sense of fun to the things he takes on—including running his own business.
Last Christmas, Brock started his 3D-printing business. Now he has a big idea: earn enough profit from the products he makes to buy the iPhone Duo before preorder day. That means turning each print, each sale, and each new lesson into progress toward his $1,999 goal.
ChatGPT is helping along the way with business advice and guidance—from designing products and troubleshooting prints to working out pricing, increasing profits, and finding ways to reach more customers. Brock is putting those ideas to work, one sale at a time.
We reached the original goal together! We’re continuing to sell, and buying a clicker supports what comes next. Spreading the word helps more people discover what Brock is making. Share this page with a friend, tell someone his story, and help Brock see how far this idea can go.
