I designed and drew an intake lip only for CHANGESUN Ø 120mm 4 blades .I do not have plan of intake lip for HAOYE FAN.
Which type intake lip would like to have? See post: 35,72,75!
There is a SOLID EDGE student version. It is a free CAD program.You can save here your plan in the .stl file then printed it .
I can send mine file if it help you.
