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.

Printed on an Elegoo Neptune 3 Pro running Klipper using Overture PETG

Model by Fotis Mint. Took about 15 hours at 0.12mm layer height
