An open-source 3D printed Prosthetic Leg That Grows With its User
⚠️ IMPORTANT - This is a concept, NOT a medical device ⚠️
This design is an experimental concept, shared for educational and developmental purposes only. It is not certified, approved, or tested for clinical, medical, or long-term use. It was not designed or evaluated by medical professionals and meets no medical-device regulations. It is not a substitute for professionally fitted prosthetic care.
A prosthetic can cost thousands of dollars, and for a child that cost repeats every time they outgrow it. For a lot of families, that puts it out of reach. This is our attempt at an alternative: an adjustable, low-cost, fully 3D printed prosthetic leg concept designed to grow with its user instead of being outgrown.

CAN YOU HELP?
If you work in prosthetics, orthotics, or medicine — or you know someone with a 3D printer and a little design know-how — we’d love your help turning this into something clinical-grade that anyone could print at home.
