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.)

Assuming prusaslicer, go to print speed settings, and look for “slow down on overhangs”. Also, under filament > cooling, there’s an option to increase fan speed on overhangs.
You can use the top left menu on the layer view to check that the fan and print speed are actually adapting properly to the overhangs.
