Nice model. =) It'll be great for the convention I'm going to next week.
Printed mine in black ColorFab PLA/PHA at 0,2mm. I might reprint it at a higher resolution because some of the buttons didn't turn out as nicely as I had hoped. My only criticism is that the hinge is a bit brittle. Would've preferred it to be a tube that you insert a thin steel wire into. Way more durable that way.
