Or a a sausage.

What capacitive touch film exists that is cheap enough that you'd want to use it, will bond to glass, resist being gouged (because it will be), will resist temperatures of well over twice the boiling point of water without sustaining damage or losing adhesion, can be removed and replaced without destroying the glass, and doesn't require specialized equipment or knowledge to install and connect?

At the time I was playing around with one and thought it might be worth looking into. Capitative touch sensors actually don't need people. I may be wrong on this, but I think they detect anything with a different capacitance than air.

These gloves can trigger it.

If you attach the sensor to the nozzle (easy) and get the bed to act as the trigger (tricky) it could be used as the probe.

I was hoping someone else might have some ideas on this part. I tried a few things (i.e. Kapton, and an aluminum build plate) but it wasn't as reliable as I would have liked.
