With the original file, the alignment between the ring and the nozzle isn't good.
I think it's specific to the ender 3 pro version. So I have adapted the STL file to be good.

This remix have two versions that impact the ring angle. On my ender 3 pro with the 90° original angle the ring isn't horizontally aligned with the print head, i have corrected this with a -2.5° correction.
I don't know if it's specific to my printer or if it's general.
