Clicking Life Counter

Updated - Use v3 of all parts, the new rotor has easier to read, deeply embossed numbers. The pin has been replaced with threads and a nut.

Inspired by Gnietschow's 'Spinning Life Counter' http://www.thingiverse.com/thing:399483

I basically tried to make the design beefier. I also added numbers directly onto the rotors. I added grips to make it easier to turn the rotors.

v2 of the end, makes the pin a little skinnier, and longer
