The tolerance on the original latches are too tight for FDM printers. The hole diameter is only 3.2mm (close fit), but even my Bambu P1S can't accurately hold that tolerance. As a result, moving the latches will rotate the screw itself in the case, causing unnecessary wear on the case. I've increased the hole diameter to 3.4mm (normal fit), which allows the latches to freely rotate AND make installation easier :).
