How to level your bed on ender 3 v2 / other 3d printers - easy process-manual on the fly levelling

please show me your calibration prints! I am on instagram as uh...I think its lost.in.tech - with dots between.
Well I was thinking about levelling and what can I say, I got a little carried away.
Levelling is a slow drawn out exercise we all have to do far too often, and I felt like we need a bit more than a sheet of paper and trial and error.
Please comment if you have anything to say!
