Business card box made of business cards

I discovered instructions for making a six-sided cube from business cards. It results in weird flaps on the outside, so I modified it to make the box above.

For this box, you'll need 5 business cards and 4 pieces of double-stick tape. Follow the folding instructions here, but fold 5 cards instead of 6. (You don't need a top piece.) Follow the assembly instructions, but make sure all of your flaps stay to the inside instead of the outside. Use tape to stick down the two loose flaps on the inside bottom and the two side flaps at the top.
