Printing bins/boxes that come out flimsy with thin walls.

[Lime green]

I'm having issues printing bins/boxes that keep coming out with thin flimsy walls. I'm using a Anycubic Chiron with .2mm nozzle. My layer height is .2, wall line width .4, wall thickness 1.2, wall line count 7, Top surface skin layers 1, top bottom thickness 2, top layers 5.
