Scavenger Hunt Box

This is a small box with enough room to hold a key. This key will be used to open a later box, which will have another clue. This is all for a scavenger hunt. The top lid and front will slide out of the base. In addition, it will have text on the top telling the user which way to slide it open. It was made using only makerbot 3d printers.
This box could also be used to hold something else small, like a flash drive or some earrings. It is durable, and water resistant, however it will not stop whatever is in it from getting wet. It should be pretty smooth.
Tolerances were already set.
