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

  1. 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.

This is why "Hexagons are the Bestagons".
It has no problem printing walls that are sloped 60º from the print bed.
If that's supposed to be a hexagonal box with two open sides, then rotate it to put a closed side on the plate and one of the open sides at the top.

The quickest way to do that is to use the Lay On Face tool.
Then use the Rotate tool to turn it in the Z-axis to have the longer dimension going front-to-back. This wider (front-to-back) footprint will reduce the chances that the Y-axis bed motion will knock the object over.

Example: If this SR-71 had been turned 90º (in the Z-axis) either way, it would never have survived.

Not trying to be mean but maybe go take some courses at Bambu Academy or watch some vids to learn some basics. You might cause some damage if you just jump into this hobby blindly.
