Tiny, robust useless box!

This build uses cheap standard components; design was done from scratch with two main targets:
- robust operation => 3mm wall thickness
- easy, fast printing => small overall size, minimum support requirements

Components needed:
- Arduino nano 168, 5V
- 9g standard tower servo
- 10k resistor
- on / off switch, 3A 125V, 5x8 housing
- USB cable
- some super glue to mount printed arm to servo arm
- 4 nuts M3
- 2x M3x12 used as a hinge for the lid
- 2x M3x16 to close the box
- optio
