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.
Mamani funds the endeavour with the money he makes from selling robotic toys he makes – his other passion, which, after building his first remote-controlled toy car as a child, he never abandoned.
