The one good print I had was put in the freezer for ten minutes. It was an item to fix a different issue; the filament dragging on the tower. Based on its shape, it would have been easy to remove without the freezer.
The glider cooled overnight in my living room. It’s so thin at the wings, I figured the PLA would be too brittle to scrape off without damaging it.
I have the z-height adjusted so high that if I raise it .05 it not longer has resistance at all.
