rear mounted 60mm cooling fan for wanhao di3

I was looking for performance of the 60mm fan and with a view of nozzle, I finally decided to draw one by myself.
Pla printed.
Pls use support type touching buildplate.
You need a 16mm m4 screw to secure the whole.
To be sure of its good performance is a PID tuning is required.
