troll money container

My friend tricked me into an unfaire bet and I made this container to give him his money....

The 3D printed parts are PLA 200 micron and they are very basic to print. 

You can watch the video I made for this here: video

To make this you need:

- some super glue - hex bolt M6x140mm with full thread    http://goo.gl/IZXfho

Depending how hard you want it to be to open you can buy different quantities of lock nuts.
