Norwich Castle is the site of the latest exhibition for Build Your Own: Tools for Sharing, which also includes a very special from e-NABLE, where numerous volunteers help to 3D print prosthetic limbs for at least eight children in need of replacement limbs. There are three 3D printers on site at Norwich Castle, and the 3D prosthetics take 30 hours to make. Parents are taught how to assemble the 3D printed prosthetics themselves, and they are provided at a cost of as little as £10, or $16.70 USD.
