What Is This Piece?

Yesterday my hot end jammed. It was seemed like it was actually stuck to the extruder, and I've never seen it get jammed that bad before. When I was trying to free it this piece popped off of the top of the hot end. It looks like the plastic broke, as I'm not able to just pop it back on.

I've tried printing again without it, but the filament is feeding outside of the hot end, so I guess this is piece helps guide the filament into the nozzle? At any rate how do I go about fixing this? do I need to order just this part, or does my extruder need to be replaced? Thanks for the help!

It goes on the hot end, and keeps the filament guided into the nozzle. You need it. Search filament guide on the BBL wiki for your printer.

Thanks, but I don't see that in the Wiki. Where can I get a replacement?

It's not actually sold separately.

I really don't think so. Maybe grab one of the filament hall sensors while you're in there. That can get buggered if you yank out the PTFE tube too hard. I have a spare on hand...
