Since i use the Mk7 extruder wheel i had to move some holes. Also the hose fiting is an M6 thread

I have not tested it yet but it seems to grip the filament good enough.

Update!

I have tested this and it grips the filament good. Now i need to make and alternate main body to accommodate Ninjaflex.
