This is an adaption of the EVA2 Klicky Probe Mount by Jlas1 (https://github.com/jlas1/Klicky-Probe) for the EVA3.
Print with screw side facing upwards and bed plate support (might also work without support, though not tested).
Update 2022-05-25: The previous version was a bit too low and did not work well with the frame mount. The new version is 5 mm shorter, therefore higher.
Here are my settings for this Probe Mount on a RatRig V-Core 3 400 with SF Mosquito Clone:
[probe]
x_offset: -27
y_offset: -25
z_offset: 1.015
klicky_variables:
variable_docklocation_x: 6
variable_docklocation_y: 7
