I added a holder for an 18mm diameter inductive or capacitive sensor and its cable.
The only other change was to lower the profile behind the zip ties and add a bit of material at the weakest point of the piece.
I use this holder for an LJ18 A3–8-Z/BX /NPN sensor on my Ender 3.
My parameter for the auto bed leveling in marlin:
X_PROBE_OFFSET_FROM_EXTRUDER -55 //X can be OK for your Ender3
Y_PROBE_OFFSET_FROM_EXTRUDER -18 //Y can be OK for your Ender3
Z_PROBE_OFFSET_FROM_EXTRUDER -.82 // always calibrate yourself!
Don't forget to enable Z_SAFE_HOMING!!!
Always be careful when changing the endstop or homing settings!!!
You can easily destroy your printer!!!
Use at your own risk!
Don't set a metal bed clamp at this corner ;)
