I saw this on Google images with a note under it stating that it is a functioning combination lock which has been 3D Printed. I have researched the piece but couldn't really find too much on it, other then the design on Thingiverse that anyone can download and use to print out their own functioning lock: http://www.thingiverse.com/thing:2047
