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.)

Overhangs are always difficult in 3D printing and your part cooling fan makes a huge difference in this. Also your print speed and temperature are factors.
This model however can also be printed sideways, you’ll have lower bed adhesion but it won’t have any overhangs this way.
