Just finished designing this - a life size (i think) borderlands 2 pistol ammo box with opening hatch/door.
Print out the strongest card your printer can handle. Prints on A4 - that’s why it’s 3 separate images.
The main challenge is working out how to build it 
as i forgot to take pictures when i was making up. sorry.
You should be able to work it out from the pictures and a little common sense!

The finished box
One end, with information
Open door/hatch
Print out these sheetson A4 card:
PAY ATTENTION BELOW FOR VAGUE INSTRUCTIONS!
The latch system that prevents the door from opening all the way - doesn’t need to be exact, just as long as you create a lump that sticks out
Glue the door on like this - only the bit with circles needs to be glued.
If you want, you can cut out each circle to add more depth to the model, but this takes a while
Lightly squeeze the sides of the door in to fit through the hole, when you release the pressure, the sides should come back.
add shading lines if you want
Your box is finished!
