1029更新：修正了风嘴比原装低的问题，现在已经和原版几乎一致，效果图就不更新了，另外我发现用ABS打印可以比原版轻很多，

bambu的工业设计非常不错，细节设计也很到位，不过我有点设计师强迫症，看到喷头外壳下面的棱线和风道的棱线元素不一致，总觉得很别扭，所以为了满足我自己强迫证所以我把它设计成了上下呼应，只是外观修改，如果你也很喜欢使用原装风道，又和我一样有点点强迫症，喜欢可以一起打印，推荐使用官方的耗材PAHT-CF耗材，当然你也可以实用ABS打印，关于支撑和支撑屏蔽我已经设置好了，并且早期都测试过没问题。已上传自己完全重建的STEP源文件。

1029 Update: Fixed the problem of the air nozzle being lower than the original, now it's almost the same as the original, so I won't update the rendering, plus I found out that printing with ABS can be a lot lighter than the original.

bambu's industrial design is very good, the details of the design is also in place, but I'm a bit of designer OCD, see the prongs below the nozzle shell and the prongs of the duct elements are not consistent, always feel very awkward, so in order to satisfy my own obsessive compulsive so I designed it to echo the top and bottom, just the appearance of the modification, if you are also very much like to use the original ducts, but also a little bit of OCD, like me, like to be able to Print together, recommended to use the official supplies PAHT-CF supplies, of course, you can also practical ABS printing, about the support and support shielding I have set up, and early are tested without problems. Have uploaded their own completely rebuilt STEP source files.

注意：

1.原装风道的拆解并不容易，由于上壳和黑色风道在卡扣处有胶水，所以拆解替换需要一定的耐心；

2.需要一颗M2X2的N52磁铁；另一个M4X2的N52磁铁;

3.再少许胶水滴在磁铁处，注意磁力方向一致；

Attention:

1.The disassembly of the original air duct is not easy, because the upper case and the black air duct have glue at the snap, so disassembling and replacing requires some patience;

2. need a M2X2 N52 magnet; another M4X2 N52 magnet;.

3. and then a little glue drops at the magnet, pay attention to the same direction of the magnetic force;
