Update1:
I have added second version for bottom of print head now you can attach bed leveling sensor (in my case it's Omron proximity sensor 4mm M12). It's connetced to duet board as E0 endstop. Works perfectly like on video :D
Update2:
I have redesigned X, Y and part of Z axis also, changed X and Y endstops to proximity sensor, new extruder carriage, 33% bigger print dimensions (from 200x300x500 to 250x350x500)
