Testing 3D Printer

Temprature, Speed, Z zero offset .... so many thing affects my 3D printer to print a perfect thing. I just have no time and goint to crazy after hours of waiting and printer give me a trash ...

So I decide to create this complicated model to test my printer, the complcated model should be relative small, and doesn't cost too much time for tuning.

Maybe you thing I'm crazy, yup, I'm crazy I think ....
