Rich is embarking on a fairly long bike trip in a few weeks – Seattle to Portland – and thought including some 3D printed gear on his ride would be a fun endeavor. His first idea was a printed belt drive, but the more he looked at that idea the less realistic it seemed. He finally hit upon the idea of creating a 3D printed bike shifter, and after an afternoon of engineering and printing, the shifter ended up working very well.
