That’s my personal PC, so I don’t care about looks, I mostly want a strong connection to the whole notebook’s bottom casing so I won’t break it by touching that part of it while taking it up by it.

I have superglue, hot glue, metal sheets, can purchase screws and such, am not limited of basic supplies, but I have no idea how a pro would go about it.

Deeper description: it’s occured to the bottom part of a notebook holding most hardware. The corner itself is empty so no hardware there. It broke off in one piece, but have itself two still intact details - one is a part of a flat surface that you put your hands on while working, the second is a bit rounded reaching the bottom.

I came to think I want to fix it with some sheet where it is flat, and then glue it to it’s curvy bottom.
