I also got improperly sized case, where PCBs won't fit.
The case can be assembled and my Rasspberry Pi fits (hard), but TFT and Piscreen PCBs cannot.
They are about 1 mm too wider than the distance between rectangular holes in smaller case sides.
The sizes are the same as dhylands wrote, only my Raspberry Pi model A is 55.7 mm.
Could you send me properly sized smaller sides of the case? (With not less than 56.8 mm between holes.)
By the way, there were no styluses in the parcel, it would be nice to get them too.
Yet the lack of them is not as show stopping as the too small case.
