UPDATE: Simple dual fan mount for MK8 direct drive extruder

thingiverse

This is a never revision based on my simple fan holder: http://www.thingiverse.com/thing:1423957 It is designed to mount two 40mm fans at the extruder to cool down the object. It replaces one of the spacers between the heat sink and the fan on the side. I printed it as it is in PLA with 0.2mm height, 10% infill and without support. After printing, I drilled the holes for the fans up to 4mm UPDATE: I uploaded V5, which is the latest and greatest. The fans are now moved a bit to the left to be more aligend with the extruder and give a better and give a more consistend cooling to the part. Over that, I made the holes for the screws bigger so that you don't need to drill them up. So basically, you can now use it directly after printig. There is no picture yet, but you can see the difference in the STLs. Side note: I printed my holder in PLA, which is not the best choice for a part which is next to the hot end. Acutally, it began to be very soft and deformed during a print (very slow printing speed, large 1st layer, 240deg at hot end for filaflex, fans disabled for 1st layer). Now, I have the fan enabled from start and the problem is gone (and my printing quality has also improved).
