The 3D Printed Gyroman

Dr. John Jameson created a unique walking toy which made use of a metal flywheel and pivoting legs to create a silly, walking forward motion robot. The design won him a Mattel toy competition, but while Mattel went on to patent the design, they shelved the idea and it never debuted in the U.S. market. Now as the original patents expire, Jameson's friend Jeffrey Kerr decided to update the design and make it 3D printing ready as a tribute to his pal's ingenuity. It's now a fully open-sourced, 3D printed toy design that can be downloaded in a variety of iterations from Thingiverse.
