Reverse Bowden Bracket for PC4-M10 taper thread fittings--mounts on Nema 17 pattern.

I designed this to allow me to add reverse bowden to my Anycubic Chiron that I converted to direct drive.  May work on other ender style printers also.  It simply fits where the old bowden extruder motor used to go.  Secure with M3 x 10mm screws and hex nuts.

The STL is already in print orientation.  No supports should be needed.   Print at .15 to .1mm layer height with a well tuned printer to create usable threads.  Do not overtighten the fitting.

Added in version REV-A which has an added feature to stop the bowden tube from slipping in the other way.  I have yet to test this version, though.

finally had time to test out REV-A and it works great.
