Disclamer: I didn't originally designe this for the MakeAnthing3D challenge but here goes. 

here is my first submission for MakeAnything3D's puzzle challenge 

I designe this based on a wodden puzzle I saw previously. It works on the simple consept that many other puzzle boxes use, a hidden mechanisem to unlock the box, namely a hidden maze.  

The objective of this Puzzle is to try to get the Inner block peice out then get the lid off so as to be able to access the compartment. 

This puzzle was made to be both fun and preactical. Fun as it's a puzzle and practical as you can store valuables in it and have them be safely lock in there by the puzzles of the box.

Some asembly is require and it would, admitedly, spoil the solution of this puzzle. However that is just due to the nature of how the mecanisem works.

Furthermore, this was made to use as little glue as possible, only needing it to connect the Lid lock pin and Lid lock dial together. The rest of the components should be able to be press fitted together and stay together with friction. And the locks on the wall, the dial lock on the lid and the inner box are suposed to be able to slide freely. 

A more detail instruction manual can be found in the PDF here

This also mostly does not need suports. It only requires it in the lid, the lid lock pin for the slots on the sides of it, and the inner block for the mazes and the latches. 

I hope you all enjoy my creation.
