Da Vinci Code Cryptex

In the book -the Da Vinci Code- a cryptex plays an important role. The cryptex is a cylinder with an important document in it, protected by a code word which can be set by turning rings around the cylinder. This thing contains the files to print the parts which make a fully functional cryptex which can be printed on a 3D printer.

Three other cryptex designs are on thingiverse: http://www.thingiverse.com/thing:1751, http://www.thingiverse.com/thing:2695, http://www.thingiverse.com/thing:2708,
