Ultimaker fanduct V2 for use with the V2 hotend, solidworks 2013 and step file includedInstructions:- print with the opening of the fan in the direction of the fan for good cooling of the print- since this print has steep angles, you get better results printing this with your ultimaker tilted (about 20-30 degrees)- *** IMPORTANT *** use nylon spacers between aluminium and fan, otherwise PLA can become too soft during printing and deform towards the hotend
