We meet Eric Harrell, who brought his collection of functional 3d-printed car engines and transmissions to this year’s Maker Faire! Eric shows us his 1/3rd scale engines, which he designs from reference schematics and measurements to highlight how real engines work. Eric has also made his files available online for anyone to make their own replicas!
