My Klipper config: https://github.com/spajo/n3p 

This mounts both Eddy and stock probes to the extruder if you need flexibility or are just experimenting.  I used threaded inserts to make the eddy a little more rigid. 

I will probably switch back to using this adapter as it also fits Neptune 3P-series after I finish experimenting with this setup.

Eddy Duo/USB has quite a bulky cable so to avoid dragging it on print surface I also designed a cable guide that replaces original X-axis limit switch cover.

18.01.2025: Added no-inserts version

I used BTT and Elegoo provided models of Neptune3Plus and Eddy to make measurements.
