I disassembled the mouse to fix the bent aluminum from dropping it and it works, but sticking the bottom part to the plastic battery tray is hard. What is strong enough to hold the plastic and alunium together?

After cleaning off the old glue from both sides I would recommend just using hot glue as it’s fast give it a good 15 min and it’s done.
