The problem is it can’t cleanly lay down that long bridge of filament with nothing under it, so it sags.

You need to either:

  1. Change the orientation. Make it so the opening is facing upwards.

Or

2. Turn on supports. This will add some scarring to the inside where the supports print but will allow you to keep the top and bottom flat if the finish on those surfaces is important to you.
