Hi, i just discover your inductive probe mount, i did mine quite differently and did not have so much issue about space (i did not need to grind the probe), but did have a small verticality issue, how do you ensure the verticality in your design? only through gravity?
I am actually looking to upgrade my probe holder and thinking of a mix of our options,
Have a look here: https://www.thingiverse.com/thing:3193744

Can you adjust easily the height of the probe?

But that nice to see other way to solve the same issue :)

Kossel - Non-invasive Inductive probe mount

I was susing a capacitive probe. So there wa only an 18mm version avaiable. Nothing thinnesr. Inductive doesn't work on Ultrabase.
Regarding verticality, I just mounted it and it looked straight! ;)
Height adjustment is just done by manually puishing it into the mount. The rest is done with the potentiometer for sensitivity.

Actually, in the end I reverted to the provided microswitch solution as capacitive probes tend to drift over temperature thus producing eratic results affecting the correct Z-height. Now with Marlin 2.0.x and an SKR 1.3 32 Bit board, the Linear plus runs better than ever! Even with just a microswitch for calibration ansd levelling.

You can follow my guide using an optocoupler

https://www.thingiverse.com/thing:3028563 (just power it with 12 V, should work. Maybe you have to adjust resistor.)

Or you attach a voltage divider ( basically two resistors in the ratio 7:5 6K8, 4K7 between 12V and Sensor output) to the output of the Sensor.

This looks like promising, how do you wire / connect this to trigorilla though?

Really cool mod! Is the results comparable to the original calibration sensor? This seems a lot more convenient.

It definetly is. And you don't forget to take the sensor off anymore and don't crush the thing into the bed! :D
Using the same sensor on my Ender 3 - absolutely brilliant performance as well.
