Hi PD! I'd say you were ambitious, and trying to clear up a problem. I looked inside myL2360DW and saw nothing that looked like that. However, I looked at the toner cartridge and saw something that resembled a part of what you show here, but since it was inside the toner cartridge I could not see the whole thing. If it is the same piece, it's hard to imagine how it would've migrated out of the toner cartridge. I am attaching an image, which may or may not make sense. If we have the same toner cartridge (TN-660), you will see this on the left side of the unit when you remove it from the drum unit. Good luck!
