What the heck is this dangling part on my X1C?

What the heck is this dangling part on my X1C ?

Just appeared today after starting a print…

Its the WiFi Antenna. It looks she come loose.

Thanks - I didn’t explore too much since the printer was actively printing.

Wonder if a bit of Kapton tape would be acceptable to reattach it?

Yeah, why not. But I think you can attach it again without additional tape. Its a simple PCB. You can press it with a bit of force back in place.
