This is a great project.
In the United States, there are approximately 1.7 million people living with limb loss. Many of them are children. This statistic is even greater if you take into account the world as a whole. Limbitless Solutions is a non-profit organization that creates affordable prosthetic devices for children. Using 3D printing, the company is able to offer affordable prosthetic arms that are functional and capable of gripping objects. Right now, children without limbs can get arms that look like they belong in The Avengers, but even more options are coming soon.
