This is my version for the extruder filament driver for my QU-DB
extruder (1.75mm filament), where I wanted to have more force applied to
the filament.

I guess this set will also work on MK7 extruder too, but may be there is room problems.

I have added an extra 8mm spring to apply more force to the filament.

Also I have change the bearing to hold a 624 bearing.

Parts that you will need:

- These two STL prints

- x2 Spring 8mm diameter.

- x1 M3 screw to hold the bearing

I used the original qu-db drive gear but I wasn't very happy with it, so
finally I changed to the MK7 drive gear which gave me better grip and
results. Also with the MK7 i could decrease the stepper current so the
motor runs cooler now ;)
