Rich Olson was needing a new shifter for his bike, instead of heading down to the bike shop to buy one he just fired up the 3D printer and printed up a new one. It is a friction based shifter which I remember having and preferring more than the click shifters you tend to see these days. With a friction shifter you simply move it to the position you want instead of clicking through the gears and hoping that the click placement is exactly where you need it. Rich has made his files available so you can also print your own if you have a printer handy.
