@NiwlCraft@mastodon.art that happens when there are long distances and the filament cools down and pulls the edges up. Try brims! Or mouse-ears if there are sharp edges (just a 1 layer circkle around where the warp happens). Using a glue-stick of some kind (made for petg of course) as a bind/release agent might help as another "throw money at the problem" option
