I've heard (and seem) many a horror story about PETG and was ready for hours of troubleshooting. Generic PETG settings in Prusaslicer and honestly this print couldn't be much better! There's a few layer inconsistencies, but those should be pretty trivial to fix after I get a temp tower done.

I did exactly one print with PETG which was a benchy and it came out great. But I only have roll of PETG and I'm dreading to think what will happen if I try to use it again since it's been sitting there for 2 years. I did put it in a resealable bag with some desiccant but even so. Most of the time I think I'm better off with PLA, but if I ever have something that will sit in the sun or otherwise get warm, I might go over to PETG for it.
