The new arm was created by John Peterson using designs from e-NABLE, an online community that uses crowdsourced design to build custom prostheses. Liam’s mother said the new arm is much more functional than previous models he’s used. Unlike typical prostheses, which can run upwards of $9,000, Liam’s new prostheses cost $50 and can be refit as he grows older. It also is customizable, with interchangeable attachments that can be 3D printed to spec.
Excellent. Wonders abound.
