Z-probe for hotend ribs E3D V6 & V5

Well everytime I try to fasten it , it shatters, maybe I use to brittle filament.
Still I publish this, to give others some ideas.
the 20mm should fit on the ribs of the hotend of a V6, and the 25mm for a V5.
the square on the botttom is intended for a microswitch.
