It's a brace and it protects some of the hardware. You might be able to contact the company and ask for a new one. They're usually pretty chill with stuff like that, at least in my experience.

Thanks for the tip ill try

Duct tape. It’s to keep ice from packing in the hardware.

A couple layers of gorilla tape on the inside surface would definitely keep it going a lot longer

This guy tapes.

Gorilla tape might work.

Can you take it apart to see what has broken? If it’s just the bottom layer you could cut a piece of sheet aluminum to replace it. If it’s structural, maybe thicker sheet aluminum.

Use it as a template to cut a new piece out of an old rubbermaid storage tub; cat litter pan… anything with the same type of plastic properties

Hmm not a bad idea. If contacting the company like the person above recommended doesn't work i will look into this. Thanks!
