I have a Petsfang Duc and Ender 3 Pro (with a standard fan). Now I purchased two 5015 - I want to print Petsfang Duc for 5015. But I found Hero Me Fanduct now I don’t know which one to print from them. What's better? Also, you and Petsfang have a version for one 5015 and two - which is better (I just start typing, I understand very little)
