its broken in 2, and the place where the screw goes is broken i had to open it but the screw was so stripped it was beyond un screwing anyone willing to sell / give for free a nerf deploy battery tray cover?
try some Gorilla Glue brand epoxy. It’s two part and it is at least as strong as that plastic. Lightly sand the parts where you’ll glue them, and make sure to spread a little onto plastic past the break for extra strength. Can always paint it if you don’t like the look. Its what I use for plastic repairs. I think it is called Gorilla Weld.
If you have a 3D printer, you may be able to make a copy of the part in a 3D modeling software, then print it out.
