Bolivian toymaker restores limbs with 3D prosthetics

As a kid growing up in poverty in rural Bolivia, Roly Mamani built his own toys.

Now a 34-year-old engineer, he 3D prints limbs for Indigenous compatriots scarred by life-changing accidents.

One of their beneficiaries is 59-year-old Pablo Matha, who lost his vision and right hand seven years ago in a mining accident involving dynamite.

Matha says the prosthesis "is a great gift." He now plays the guitar to earn a living.
