Like this one, maybe, as mfleming already pointed out...

It would be better a completed sealed box, up, down, left and right. One of it's cover should be removable, hold by screws, in order to replace dead battery or bad circuit.
The mini-USB conector, which should be accessible by hole in the HP41 case, can be placed on side of that case, aligned wth HP41 hole.
