"Russian" auto level holder

I came up with this method of installation for the following reasons.
1) I do not need an auto-level sensor anymore. I have modified carriage Y, X, Z on my printer. And I installed the glass on the table. My printer has no more errors, which should correct the auto-level.
2) The inductive sensor is more accurate than a mechanical switch.
3) I already have an inductive sensor, I already paid for it, it should work.
