How to print a inclined hole feature correctly

WHChu 2021-6-18 570

Hi

As I need to print a large model with a hole in the center on my Anycubic Mono X, I had tried to print a small model first (see attached file). I found that the printed hole size is 0.3~0.4mm smaller than the 3D model.  I have already applied for tolerance compensation, but there is no change.  I would like to know is there any setting on the program or method that can reduce such difference.


Thanks!
