So either a broken 3DS or if someone knows of a place selling just the case, that would be fine too. But I would need the nub as well (although I could buy the part separate if need be).
Sadly, DX doesnt have any 3DS cases. A few DS cases but none for the 3DS yet. And I know about the nubs Palmer mentioned. I plan to buy 2 when he starts selling them. They won't have the nub cap unfortunately. I'll have to make one.
