just a case for my spare computer mouse its 62 mm wide and 125 mm long if your mosue is bigger then that you will need to scale it up in your printing software, i sue a rubber band to keep it closed

you might need to sand the sides of the joints to make the fit together, also you need to melt or glue the pins to the outside pices of the joint, the joing covers are kinda useless i jsut think it makes the whole thing look more neat
