Wanhao i3 mini FanDuct with FanCover

Rework of the impressing desing of MAL_0703 to replace the stock fan mounting and improve part cooling - made it shorter (and a bit simpler), no need for shortening anymore - changed holes for mounting screws to long holes for individual adjustment as there seem to be different versions of hotend mounts around - added a cover for the fan - duct printed with 0.2/25% - cover printed with 0.15/25% - everything mounted using stock parts Cooling effect is significant. After printing and mounting the duct I went for the cover. I think I would not have been able to print the 0.5 mm Wanhao-logo with stock setup. Tried similar stuff a few times and thought the printer would lack accuracy.
