(moved) lens gear

THIS DESIGN HAS BEEN MOVED TO YOUMAGINE:
https://www.youmagine.com/designs/labeled-lensgear-set-for-geared-follow-focus

Reasons:
http://marcuswolschon.blogspot.de/2014/01/leaving-thingiverse.html

This is a lens gear for a 65mm lens to use with a follow focus.
Adapting this to smaller lenses should be trivial.

0.8mm pitch, 97 teeth to the full circle.
I tested these to be compatible with industry standard follow focus equipment of the same pitch.

(These gears are sold for obscene prices, so I printed my own.)

Update:
To make construction with this part easier, I also added the counter-gear for it.
Ready with an M8 trapped nut and tapering to make inserting nut and shaft easier.
I choose a very thick M8 shaft to allow cheap and readily available 608 skateboard-bearings to be used.
(The rounding between trapped nut and gear is to increase strength.)
