UK-based college student Tom Fothergill noticed that his mother's electric whisk uses a gear system--and that it could function better. Fothergill has knowledge in the areas of electrical and mechanical engineering, and put that to use in redesigning the whisk, settling on a 3-bladed design that could improve mixing speeds. Designed using Solid Edge CAD software and printed on a Creatbot Fullscale 3D printer, Fothergill's 3D printed electric whisk uses electronics from a cordless screwdriver and 9 separate 3D printed parts. He's made the design available for download on Thingiverse. Read more about his design process here: http://3dprint.com/86221/3d-printed-electric-mixer/
