Due to a design flaw, the air outlet cover of the Xiaomi Air Purifier 2 cannot be easily removed, making it impossible to clean the blades. I used pliers to remove the original air outlet cover and then printed a replacement one. The printed air outlet cover was attached with double-sided tape. The angle of the air outlet cover in the picture differs from the original by 2.72 degrees. The issue has been fixed in the released files.
