Little rubber ring

I had this little rubber grommet or ring show up in my machine one day. I picked it up and saved it, but never had any issues from the GF so didn’t think much of it. Well I recently got a new unit because of lid hinge issues. When the new one showed up another rubber ring showed up in the same place as the last. Again I am still not having any problems with the GF funtioning.
I really just wanted to know if anyone else has had one of these show up and/or know where it came from. I don’t know if it is going to cause any issues down the road.

It’s part of the screws that secure the glowforge for transport. Just put it with your other important orange and red bits.


Shouldn’t there be 2 then?

Yes, there are two. The other one is probably still attached to the screw lock.

ill look, thanks for the quick replies!

Thanks everyone! @happygreens7, here’s a picture of the knob it came from.
