Pla can get brittle if exposed to a ton of moisture, so if it’s expected to flex, another option should be preferred- ASA, comes to mind.
But if there no real load on this box…. Pla or petg would be fine.
I a rack-hanger thing for my shaving stuff that has held up admirably for years.
I've had pla plant identification sticks outside for 3+ years in the sun, rain, and snow. One with a clear spray one without. Neither has deformed barely at all. Agreed, if it has no load it should be perfectly fine.
I'd be more concerned about heat on PLA than anything else. Black PLA, or inside a car... makes prints all droopy and sad.
