Ender 3 S1 Fan Duct Simple Improvement

prusaprinters

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
