马自达 MX-5 空调直吹冻手，出风口添加扩散器，完美解决冻手的问题。

之前做的挡风板也有效，但是不够美观，所以做了扩散器。

建议使用 ASA、ABS 等材料，获取良好的耐热变形效果。

The air conditioning of Mazda MX-5 blows directly on the hands, causing them to freeze. Adding a diffuser to the air outlet perfectly solves the problem of freezing hands. 
The wind deflector we made before was effective, but not aesthetically pleasing, so we made a diffuser. 
It is recommended to use materials such as ASA and ABS to achieve good heat deflection resistance.
