New in this version: Lasercut the parts from 3mm wood (except for the \"circuit board\" which needs 1mm wood). Assemble the electronics on the 1mm wooden board (or however you prefer), put the servo in the designated hole, connect all the wires and assemble the box.If you mount a microswitch of the same type I made room for, use 6 of the spacers included on sheet 2 to give it the proper distance from the mounting board in the box (3 on each M3 screw).Remember to glue/tape/fasten the flat cable running from the switch, so it doesn't come off after too much fiddling to align everything...The wooden arm should hit the switch when mounted with small screws to the servo arm, but I've had varying degrees of luck with returning the arm to the correct position where the lid closes all the way, so YMMV...By the way: All credit goes to Saskview on Instructables http://www.instructables.com/id/The-Most-Useless-Machine/
