Cryptex simplified (locked secret container)

-----------------------------------------------------------------------------------------------------------------
This is a simplified CRYPTEX (a locked container) , a cryptex without any numbers printed on. This feature leaves the user free to create the combination he would like in an original way! Add SYMBOLES, LETTERS, DRAWINGS, DOTS....GET CREATIVE !!!

To give you inspiration, i drew one little dot on each roulette, and when the dots are in a specific pattern, the lock will open and reveal its content. (see picture above)

I MUST SAY THIS ISNT THE BEST CRYPTEX OUT THERE FOR A FEW REASONS
here's why:
-Roulettes needs to be really straight to open it (SAND DOWN the sides of the rectangles)
-A little bit too much space between the roulettes and the body
-The first rectangle needs a little sanding down
-Able to see the location of the notch on the first rou
