Da Vinci Code Cryptex

I've tried other designs like this http://www.thingiverse.com/thing:651654
but the wheels didn't turn ok (so tight), so I designed my own version for this nice toy.
The secret is fixed, I mean, you need to choose 6 numbers and print them. You can change the sequence of these numbers, but you can't fully personalise the secret like other designs.
One advantage, this prints faster (less parts) and the usefull inside diameter is bigger.
Nice prints !
