The knife fight scar isn’t part of the model. Wondering if that line is the z seam?
My PETG prints were not tuned well, they had bunch of warts (bad retraction/priming?) on the inside wall. The outer surface was smooth, of course what we want is a smooth inside surface, I just sanded down the warts to get smooth enough finish I could live with.
Next time though… I’d look at the slicer preview before printing and maybe tweak z seam corners to help hide retraction/priming issues.
My wart stricken part had “Hide Seam”, maybe “Smart Hiding” would have worked out better?
Seam Corner Preference = Hide Seam
Seam Corner Preference = Smart Hiding
