This a remix of Tech2D's Hypercube E3D extruder mount with M18 probe. I didn't like any of the ones I saw because they seemed a bit clunky so I created this solid piece.

I used the following settings for Marlin firmware:

define X_PROBE_OFFSET_FROM_EXTRUDER 28 define Y_PROBE_OFFSET_FROM_EXTRUDER -5 define Z_PROBE_OFFSET_FROM_EXTRUDER 0
