This is the Useless Machine by shiftux with some modifications: Print all of the parts. You will maybe need some support at the lids. All other parts can be printed wihtout support. I designed my parts with 3mm holes for M3 bolts. Maybe you have to rasp the hinges for a better function and add a little hole to the motor mount. You can also add a rubber band to support the closing. The wiring diagramm can be found here: http://9x20lathe.blogspot.ch/2010/01/components-and-schematic-for-useless.html
