A trained Mechanical Engineer and lifelong tinker, Garrett chose to attend Cal Poly San Luis Obispo's engineering proram because they had a 3D printer... back when they were called "rapid prototypers". "The first time I held something I designed and 3D printed, my mind exploded. Just hours earlier my idea was just a thought - and now it's a thing I'm holding." Now, years later, Garrett brings his love of tinkering, inventing, engineering, and 3D printing to the Makershop community.
