Mouse case for a Logitech 903 lightspeed wireless mouse. I printed it in PLA no supports. 1.75 mm filament fits in the hinges. Superglued some 3 x 10 mm magnets in the magnet holes. It's definitely not as snug as I'd like though, my 903 still rattles a bit inside the case.

v2 I fixed a problem with the magnets. I haven't printed this yet though. Original was way too big for magnets since I'm a scaredy cat. Toned that down so it's a smaller fit. Also raised the surface so the magnets are closer to each other for a stronger hold.
