The e-NABLE project is a non-profit volunteer international organization that determined to change the way prosthetics are designed and created. Celebrating its second year, the e-NABLE’s “Helping Hands” initiative attempts to supply people with missing or deformed limbs with prosthetics, designed and built by its team of knowledgeable volunteers. It’s also an open source project that believes in sharing design information that can benefit everyone. One of its volunteers is Samer Najia, a do-it-yourself master craftsman and IT consultant who, along with his mechanical engineering and big heart, has donated his expertise to the project. Dan and I ask Samer about his experience with building prosthetics along with his own personal hobbies of building aircraft and improving existing maker tools.
