Trammel of Archimedes Desktop Spinner

A Trammel of Archimedes with three sliders, where the center of the sliders is fixed and the channels rotate. Makes for a fun little desktop spinning toy. The result is essentially a pair of gears with a 2:1 gear ratio. Unlike a pair of traditional gears, they both rotate in the same direction. Website: Patreon: #lego #engineering #trammel
