Useless Box/Machine

I know the useless box is an old concept and that there are a few on here but I figured I post it on here anyways. I made this about two years ago because none of the useless boxes on here looked clean nice. They were all fairly clunky and required to many parts and hinges. I came up with something fairly small, compact, withe the batteries loacted inside the box. It's really easy to print and assemble if you know how to solder and read a basic schematic.
