83-Year-Old Inventor Designs Inexpensive Open-Source Filament Extruder

Never too late to invent something great:

Hugh Lyman, an 83-year-old retiree from Enumclaw, Washington, won The Desktop Factory Competition with his design for a low-cost, open-source machine capable of turning resin pellets into inexpensive filament for 3D printing. The competition, sponsored by Inventables, Kauffman, and the Maker Education Initiative, required that the parts used to make the machine could cost no more than $250.
