This direct drive mount is a remix of the "TEVO Tornado Bondtech BMG direct drive mount (remix)", https://www.thingiverse.com/thing:3995514 by QCPassed.
It will fit the Ender-3 but should also fit the TEVO Tornado as well as the CR-10(S), all with the same X-carriage and hotend design.
There was an offset of the BMG extruder's outlet and the stock hotend's inlet of
1.5mm in +X and 1.7mm in +Y direction.
I changed the extruder mount accordingly, which was quite easy possible thanks to QCPassed delivering the Fuision 360 file with his remix.
In addition I added a cable mount. Please check if the cable touches the right Z-strut when moving to max Y direction. I changed Y-max to 220mm in the Marlin firmware.
F3D and STEP files were added as well.
Added images to show how to orient the object on the bed. I put a support blocker over the BLTouch mount including the carriage mount holes.
I set "support everywhere" in PrusaSlicer/Slic3r.
