Renkforce RF-1000 Double Fan upgrade

The Conrad Renkforce RF-1000 3D Printer has a tiny fan and a very massive extruder. I had a lot of issues with the small fan and decided to upgrade it with two 60mm Fans, so that the extruded filament can cool and doesn't get reheated a lot by the big extruder.
Please read the Instructions before printing!
