Original file worked well but only one screw aligned with the carriage, and the Z-offset would shift occasionally. CAD isometric view shows what features were tweaked.
The fan style or mounting tabs changed and required carving a little notch out of the fan recess
BLTouch mounting holes now self tap with original mounting screws
The author remixed this model.
Change log:
added tab and hole above BL touch bracket, use original mounting screw
made BLtouch mounting holes smaller for self tapping with stock machine screws
removed notch in back right corner of fan slot
