Combination safe, 8 rolls, >200 Billion possibilities

Update 29/11/2015 : New rolls, now works fine, you can change the code as you wish

8 rolls cryptex, > 200 billions possibilities.
Work in progress, you'll need to do a little bit of filing and sanding to make it work.
Print every part in .25mm except the letters (wheel_0), 0.15 to ensure they are readable.

Need to improve the rolls system, had to glue wheels together to avoid slippage, so code cannot be changed once decided. Will be fixed soon.

body0 and cap2 should be glued together,
