fan mount for wanhao i3 v2.1

had a problem with my dii cooler i printed out for my i3 v2.1 as it wouldnt fit after id replaced the heat block with a china ebay cheap one as thats all i had. and with a 12v 40w china ebay 99p heater as the hot end had to have a 6mm one not the stock 6.25mm as it wouldnt fit. well i was using my blower fan strapped to the printer and well that didnt cut it so i decided to model one up for my exact build and wow its awsome works a treat and the fan just slots in and thrusts air through well. lo
