I'm just going to print some round buttons that have a stick going down to the real buttons. I may make the button holes bigger, though, in version 3.0. I'm going to experiment with making some clips, as well, to clip the board down and the case. Right now both are connected via friction, which works fine, except if you were to drop it everything would go flying everywhere. Plus, the friction parts would ware out after a while, and it's stop holding together. Best to clip it down.
