But there’s a problem: the feeler gauges are protected from rust by a thin film of oil, so I expect I have contaminated the print bed in the process

How Thick is a Piece of Paper?
Following discussion on a Facebook group, I decided to find out what my actual Z offset gap is and ordered a set of feeler gauges.
0.05mm

Re: How Thick is a Piece of Paper?
I've had some thoughts on this.
The "thickness of a piece of paper" is a rule of thumb; the actual correct Z offset will allow sufficient gap for the full amount of filament to be extruded (as calculated by the slicer), while not being any greater than necessary so that the filament makes good adhesion with the print bed.
We will only know the gap is too small if the extruder clicks while printing layer 1, so what we need is a single layer test file for calibrating Z offset.
