This is a "useless box". If you're unfamiliar with them, they are basically just a fun project to make and serve no purpose other than to turn themselves off when you turn them on. See the video for demonstration.

First... I should say that there are probably better boxes on this site...

Please edit this in Autodesk 123D Design before making one! The STL provided is for display only, do not attempt to print this as 1 piece.
The files will likely need adjustment depending on how your printer works.. do some test slices. I had to do some sanding/filing to make it all fit together nicely. I'm sharing the 123D files so that any adventurous tinkerers out there can edit the design to suit their needs or use as inspiration for their own project... this isn't a "turnkey" print! :)

1) The motor stand will need to be adjusted if you use a different diameter motor than I did
2) I sanded/filed some things quite a bit after printing. I've adjusted some of the things I sanded, but have not printed another to test fit!
3) I'd recommend slicing it up and printing parts to make sure things fit for you.

Mine works awesome... here's a vid:
