In response to a Thingiverse Group member seeking a good 3D printable Orrery model, FAA Air-Frame design and repair specialist Joel Leathers got to work. Leathers, who owns 8 desktop 3D printers, designed the working mechanical model of the Solar System, featuring Venus, the Earth, and the Moon rotating around our Sun. The Orrery includes 10 parts that are 3D printed, as well as a motor to spin the planets. Check out more about the design process here: http://3dprint.com/88344/3d-printed-...-solar-system/
