Flashforge Creator X Active Cooling Fan
This is a remix of a fan that was posted on here but I currently can not locate it. Anyways, I like using PLA and needed a simple fan for one extruder. I also only use one extruder on my Creator so I took off the fan from my second extruder and put on this shroud. I've gotten really good results with this design. The only drawback is that the fan is on at all times but this hasn't reduced my print quality. Simply set your second extruder temperature above 50(i have mine set to 60) and print away!
