First PETG 3d print in a while. Main body seems fine but overhangs are not. Unsure why. Need to investigate. (it’s a phone stand, the central portion swings out and makes a triangle, holding phone in that curve.)

PETG usually needs some cooling for overhangs but not too much - try 30-40% fan speed just for those sections while keeping it minimal for the rest of the print to maintain layer adhesion.
