Summary

Cryptex from the Da Vinci code
Design based on the following instructable:
http://www.instructables.com/id/How-To-Make-a-Cryptex/
Made in Siemens NX 9.0
Printed with a Printrbot Simple Metal

Instructions

cryptex outer wheel and inner wheels should be joined together (I used an epoxy resin) such that the hole of the inner wheel is underneath the character of interest. The wheels will not be centered when the inner wheel is placed inside the outer wheel, orient them as depicted in the picture, otherwise the pins may not have enough room to rest when the wheels are scrambled

cryptex slider with base should have 4 pins in total, each long enough to fit in the slider, the inner cylinder with base, and the inner wheel, but not so long as to hit the outer wheel
