I printed this with the stock shroud, installed it and printed again to compare the difference in print quality -- I thought this would improve the 'back' of the prints, but it actually made it worse. I think the ring is just a bit too restrictive. As others have said, a stronger fan might fix this, but maybe if the ring was larger it might fix this?
