Something broke, help with ID

I've been struggling the last few days to get a decent print. Troubleshooting things on the feed side, I had recently removed to Bowden tube from both connectors and while loading a fresh spool of filament this little bit plunked down from somewhere onto my print bed. Any idea what I broke?

    It looks like it might be part of a microswitch. Would guess it came from the filament runout sensor (which has a microswitch inside). If filament sensor is okay, check the Z and X limit switches.

    As you've been messing with bowden connectors, I suspect that it part of the blue retainer that you press to release the tubing - there is a metal gripper inside the blue plastic part that does the gripping, and they fail - you can buy the blue collars on aliexpress

    100% certain that is from one of the two bowden connectors.
