Labyrinth Gift Box - Tiny Money Keychain Puzzle

I really enjoyed the original gift box that sneakypoo created (https://www.thingiverse.com/thing:201097), but wanted a smaller version with the possibility as a key chain. I shrank it by 50 percent of the height and modified to fit while adding an optional lid with a key ring.

It held my US dollar nicely when quartered and rolled (fold in half and then in half again and roll it up).
