模型模仿的是消防中常用的上喷水幕喷头。

模型接口直径24mm，是光孔。如果想要螺纹的话，这里提供了原始模型文件，可以自行更改。

我设定的支撑是树状支撑，切片时需要较长时间。模型打印完拆支撑的时候需要小心一些，最好使用水口钳/老虎钳等工具来辅助完成。

The model imitates the commonly used upper water curtain nozzle in firefighting.

The model interface has a diameter of 24mm and is a light hole. If you want a thread, the original model file is provided here for you to modify it yourself.

I set up a tree-like support, which takes a long time to slice. Be careful when removing the support after printing the model, it's best to use water pliers/tweezers or similar tools to assist in the process.
