Where can I get new parts that was damaged from swollen battery?

Hello, I have a razer blade 15 2021 model and the battery has swollen badly. It's been a while since the purchase, I first removed the battery before it explodes and kills me. But doing so, the screws were damaged and I couldn't open it at all unless I damaged it. So the bottom right part of the cover where the screw's at got crooked, probably not ideal to fully enclose the parts inside. I'm not sure what the bottom cover thing is called, but that is what I'm trying to buy. Does anyone know where I can order that piece?
