Case for EiBotBoard (EBB)

This is a small case for the [EBB from Brian Schmalz](http://www.schmalzhaus.com/EBB/).
I was not satisfied with the unprotected EBB at the [EggBot](http://shop.evilmadscientist.com/productsmenu/tinykitlist/171-egg-bot) from [Evil Mad Scientist](http://www.evilmadscientist.com).
So I've created a small housing for the pcb.
