Flash Drive Cryptex - Combination Lock for your data

Make your USB stick physically safe by printing a combination lock for it. The NSA won't stand a chance!

This is still a work-in-progress. It does work, but there are still some things that need improvement. I would be happy to hear your ideas and thoughts.

Please also take a look at the customizable rings for version 1

Again, I would be happy if you'd leave a comment.
