Battery Cover for Crystal IS33 Mark III Prototype

It always irked me that the 3 ribs seemed to be on the wrong side to actually grip when sliding and the four little tabs were just too weak. There was no need to have a taper! Just keep a constant thickness for better strength. The channel for screws was an especially nice touch, no fancy shapes required.
