Overature PETG is a good filament with a mid-range dimensional tolerance of ±0.03mm and currently priced great on Amazon for only $18.99 for a 1 kg spool. The price was for the White PETG that I tested, other colors varied from $17.99-22.99, still great value. There used to be a limit in the colors Overature offered in their PETG but that seems to have changed with Amazon listing a wide variety of color choices. My test prints came out great, especially on my Prusa MK3S+ and printing directly from my Sunlu S1 Filament Dryer. I live in an area that has frequent high humidity so I try to keep PETG dry for best results. However, I did run a test after letting the filament sit out a week, which was hot and humid, without a change in print quality.
Buy For: Higher-than-average dimensional accuracy at a great price.
