I lost the battery cover for my wireless mouse and got tired of the battery and USB receiver falling out. The cover is a pressure fit and is a little difficult to take off. I recommend printing in PETG. PLA tends to deform over time.
Also fits the Blackweb wireless mouse Model: BWA18HO017. Thank you @Nebjoe88_1400712 for testing.
