RE: How i fix it
Not sure from the photo but I guess it's the Z seam you're seeing. On objects with edges, the slicer will do its best to hide it in those edges but on round surfaces like this, there's no place to hide it. If you can print the object in vase mode, there's no seam. But most functional prints won't work well in vase mode. So best you can do is to play with the seam position in Print Settings->Layers and Perimeters->Advanced. I usually set it to Aligned for cylinders like this. Or you can then paint-on seam function to put it where it is least visible. In many cases you'll have to do post processing aka sanding and polishing to make it completely disappear.
