Wanhao i3 Back Plate for 80mm and 70mm Fan

This is my design of a Wanhao Duplicator i3 (v2) back plate for use with 70mm or 80mm fan for your choice.

Mod recomendations:
1) Take cover with fan off a power supply and install without cover
2) for 80mm back plate will have to cut inner side of fan body to fit the back plate mounting holes
3) will have to cut some plastic off a switch to fit.
4) Get a reobus (fan speed controller), set speed to 30-40% Now you wont hear it anymore.
5) Will need a longer M3x10 screws
