I created this mount for the new style M2 with the V4 hot end. I have three 3D printers and I'll never attempt another print without a BLTouch installed. Perfect adhesion every time and never have to level a bed again. I use multiple materials for print plates and can switch between them at will without re calibrating my Z stops, etc. Hope that this helps you out. Of course you have to modify the Marlin code per the instructions that come with the BL Touch.
Choose supports from build plate only if your software allows., Print with the side that contacts the extruder motor on the bed.
I found the core design of the filament guide on a makergear forum (sorry, can't remember who posted it) and modified it to include the BLTouch bracket.
