I needed this mount for my ERCF system. I designed this and tested it and all fits up perfectly on my end. Remove the 3 countersunk screws on the extruder mount and install this with an M3x10mm bolt. Print as shown in the pictures. 3-4 perimeters, 15% infill, I highly suggest a stiff filament for this. I used CF-PA with great results. The bowden fitting threads in with modeled threads(m6).
