'Tony Stark' delivers bionic arm to child

Manero, a #CollectiveProject college student, founded Limbitless.  His company builds and prints, on a 3D printer, low-cost bionic limbs for children around the world.

Alex is 7 and he was born with a partially developed right arm, The Collective Project's video explained. Despite that, Alex still loves his super heros and riding his bike like any other 7-year-old.

Manero has also allowed the plans for the arm to be downloaded to allow anyone with a 3D printer to make one themselves.  The cost of the plans - nothing.  The cost of the supplies run about $350, much less than a traditional prosthetic.
