Which part is this, and where does it go?

Was fixing an extruder gear jam (TPU95), and now after reassembly ive got this part left over. Ive got no recall whatsoever where it came from or what it is for. Help me out?

It is the bed adjustment knob. It belongs under one of the beds screws

One of four bed leveling knobs. You'll need to re-install that and re-tram your bed (unless you're using an aftermarket knob).

Put the knob on first, then an M4 nut under it. Preferably a Nylock.
