(moved) lens gear

thingiverse

This design has been moved to YouMagine (https://www.youmagine.com/designs/labeled-lensgear-set-for-geared-follow-focus). The reason for the move can be found in this blog post (http://marcuswolschon.blogspot.de/2014/01/leaving-thingiverse.html). It's a lens gear for a 65mm lens to use with a follow focus, and adapting it to smaller lenses should be easy. The gear has a 0.8mm pitch and 97 teeth to the full circle, compatible with standard follow focus equipment. The designer printed their own gears as they are sold for high prices. You can find a related blog post (http://marcuswolschon.blogspot.com/2011/05/3d-printed-geared-follow-focus.html) and a video in action (http://youtu.be/bRS5ZIMN15A). An update includes the addition of a counter-gear for easier construction, using an M8 trapped nut and shaft.
