This stuff really amazes, not so much the fact that a prosthetic thumb can be 3D Printed, afterall we have seen so many other awesome things printed out this year, but the fact that the savings are almost unbeleivable. This prosthetic thumb was printed out by a man who refused to purchase a real prosthetic because of the $5,000 price tag. Instead, what did he do? He used his 3D Printer to print out a thumb that was probabyl better than the one the doctors offered. Price tag? About $25.
