Hi jjuasjjuas2. The push-fit has a M5-thread, which is inserted in the manually tapped hole on the extruder plate. The instructions say: "Use M5 screw tap to cut thread for push-fit bowden connector on base plate..." ;-)
Currently I don't have STLs for MK7 drive gears, because I haven't got any reliable dimensions of it, sry :(
You may download and change the .scad file according to your dimensions and export suitable STLs. Just use the free software OpenScad.
