Curving edge above 45 degree overhang

This is how the part printed. The bottom edges are supposed to be straight lines.

Here it is from the bottom. No problems with bed adhesion. The curve is after the 45.

This part is just over 200mm long on this edge. It may be hard to tell from the pictures but the edge after the 45 is curved out and downward. The top edge and the edge on the bed are straight.

Polymaker PETG printed on MK3 print temp 240c-230c bed temp 90-70c. Also curved with supports.

Has anyone seen this before? Any thoughts on how to fix?
Thanks

Warp - my guess is a thermal effect caused by disparate cooling of different part layers during build up. An enclosure might help by allowing better thermal control.

Warping does occur even with PET(G). I use an enclosure and the ambient temperature reaches 60° C and above, but it still happens unless you make use of support structures. The latter does help quite a bit.
