this is based off the bo1/bo2 aether mystery box. the brown that i used is not the actual color of the mystery box from the game. i didnt get the dimensions right for the box either. enjoy!

size: about 5.8 x 2 x 1.6 inches

one gray square gets glued to the top of the lid and the bottom of the lid, and the other gray squares get glued to the front and back of the box.

put the lid on the box then align and glue the 2 hinges to the back of the box. 

use the hinges on the lid as a reference to where to put the hinges.

make sure not to glue the hinges to the lid, just the backside of the box.

the hinges should sit flush with the top of the lid

there are holes in the side of the box to make handles. i used 550 cord, but you can use something else.

the hole diameter is 0.2 inches.
