About this 3D model
As the 2BEIGH3 Printer is a large unit, there are times when I want to take advantage of very small nozzle sizes. To do so, I designed a 2:1 gear reduction system that uses the standard mounting holes. A second requirement was to maintain the belt path. To accomplish this, two idlers are used. The Belt System for the 2BEIGH3 is the XL 3/8" .200" style. Operation is best demonstrated in a video: https://www.youtube.com/watch?v=pD0TGcQcKG0&feature=plcp
