Can anyone tell me what this part is?

Can anyone tell me what this part is. I found it in my poop bucket a day or so after a massive clog which may or may not be related…

it appears to be a shield of some kind.

On the reverse side is some adhesive that has apparently let go. On the shown side there is some what looks like residue of some filament.

I’ve felt around in my internal poop chute for any adhesive sticky ness but no joy.

Thank you. That was the right answer.

Best Regards,
