Instruction to it:-

1. A box with can be hidden compartments.
2. There is a box with many compartments, out of which, only one can be opened without a key. Its cover is the file named "box cover".
3. There is a circular emptiness that would be filled in with the part printed in the fille names "circular holder". It is crucial to print the "key", because without it it will be very hard for anyone to open the compartment easily.
4. The file named "hidden opener" is what'll actually hide all the bottom compartments. Insert it in the space provided on the top of the box. Use the key to open the "hidden opener" or it will be the same as opening the "circular holder without its key.

I assure you that opening the structures using the "key" will be very hard to open without it.

*Remember before printing, it has my name on it*
