I had support turned on (which you can see in the background *is* being provided for an overhang that hasn't yet printed), but these two openings in the front needed it, and they didn't get it. You can see the sag. What should I have done so that they too would have been supported?
This is the object being printed: https://www.thingiverse.com/thing:2812350
Please advise.
I'm using PETG using a volcano 0.8mm nozzle at a 0.2mm layer height, 0.96mm width, on a Prusa I3 MK3. I'm running the current version of Simplify3D.
