I am the owner of e3D hotend v5 direct drive and am thinking of getting the SeeMeCNC EZstruder extruder as my direct drive system. Does your product snugly fit EZStruder ABS injection molded plastic part? I checked your drawing of the groove mount against J-Head and it's a bit different. (I have a J-Head groove mount perfectly fit with EZStruder though) I search online and I havenn't seen anyone mounting E3D directly to EZStruder. I am a bit concerned here.
