Hero Me Gen 5 CR-10S Pro Gantry/V6 Hot end by markjhatch

I couldn't figure out how to attach securely the recommended gentry for CR-10S PRO with V6 hot end. Found that espenjohannessen (see https://www.thingiverse.com/thing:4498232 ) had already created a Fusion 360 file for the CR-10S PRO V2, so I modded it for my needs.
I had to lower the mounting positions 1.25mm so that I could touch my hot end to the bed before the X axis supports hit the motor mount in the rear. Makes it a tight fit to tighten up the bottom wheel on the Gantry, but plenty of clearance if you raise the X axis and get to it from under the axis.
Included both the stl and f3d files.
Installation requires removing the gentry and screwing in the adapter from the rear using the captured nuts on the front.
While you have the gantry off, if you don't mind drilling holes and taping them on the top, you can use one of the may generic "L-brackets" for BMD extruders along with a pancake stepper to get a pretty nice direct drive. This design puts the stepper on the back to help provide some better balance on the X axis. This needs to be a pancake stepper to clear the Z axis uprights. See two photos.
NOTE:
After I leveled the bed, I still could not get the Z axis low enough to set Z offset. (I have solid bed mounts and I probably cranked them down to much. )
I could have lowered the Body of the Hero Me another 1mm by moving the mounting holes down, but that would have required disassembly of the X gantry. Instead I found the following thing that provided the clearance needed to lower the Z further:
