Identifying a broken part

Hi.

I was cleaning out the bottom of my H2C after a print fail involving a large gridfinity grid coming loose when it was almost finished and wrapping itself round anything it could!

I found this in the bottom, clearly not an artefact of the grid, it being metal and all, so I am thinking that it has to come from the tool head or somewhere. Has anybody got an idea as to what it might be and where I might find instructions on how to replace it?

It seems to be made of some sort of sprung steel which I believe may have been curved before it was stretched out towards the right and snapped.

On the left-hand side of the image, attached to the spring steel is a rubber pad.

The whole piece as stretched here is about 15 mm across, and the rubber pad is about 10 x 5 mm.

Thanks..

I believe that may be the nozzle flow blocker.

It comes with some spares, but you can get replacements here: Flow Blocker | Bambu Lab US Store
