This is bowden extruder which can adjust tension of spring easily with M3 allen wrench.
It is for MK7 and MK8 drive gear and 688ZZ(8x16x5) bearing.
edit
I have now put 1Km through the extruder with no issues
Remixed to use a standard push fit with a 1/8th(10mm) thread and now M6
Filament is guided all the way through inside extruder, designed to use pfte all the way to the drive gear.
It is 17mm thick with a 2mm recess for the motor and designed to mount on the wall, depending on the mounting the bolt size might differ.
I used Four 25mm M3 bolts. with enough length to mount it to a 5mm panel.
Depending on mounting style and drive gear, you will need to print out the following.
Arm part a & b and base to suit drive gear.
Face mounting.
Spring adjust short
Motor mount.
Spring adjust long and cover
