UPDATE - Included new (untested rear plate). I wasn't very happy with the clamp version to hold the belt. This is more HeroMe-ish. If you try it out, please let me know how it works. I have one ready to test but I just haven't had the time.
I just confirmed this will work with the H2 V2.
This is the current mounting setup I'm using for my BIQU H2 extruder on an MGN12H linear rail. It's rock solid.
I made this so I could easily remove the extruder without having to deal with removing the actual mount point to the rail. Use M3 screws on back belt clamps. The tolerance should be tight enough to hold it well.
BLTouch Offset is -39mm for X and 0 for Y. The assembly moved the nozzle forward 9mm from center on they Y axis.
