This design optimization is for people who has cooling efficiency problem with his S1 and you don't want to add any weight to this super heavy Sprite thing.
Since I found that the S1 has more stringing than the V2 has. I made some investigations and experiments and found that the stock fan duct has a little bit deviated blowing direction. And I made an improved design that can significantly decrease the stringing. Please print with ABS or PETG to avoid thermal deformation.

 

這個設計是在不升級Ender3 S1吹料風扇的前提下,把吹料嘴的角度做小小的改良,讓風更準確的吹向印件熱點上,實測對爬坡架橋品質以及減少牽絲都有良好的效果,但因為它太接近加熱塊了,建議使用PETG或是ABS等更耐熱的材料印製以免變形。列印底部接觸面積很小,建議可以設大約5mm的裙邊以免倒塌
