If you're printing display pieces in PLA, I find that using 4 outer shell layers plus lightning infill will give you much sturdier models that are easier to remove supports from without breaking, and use a lot less filament than standard settings.

Maybe everybody else has been doing this all along, but I often find myself just using the default settings (which in Bambu Slicer is 2 shell layers, and I think it's also 2 in Cura) along with a bunch of infill that doesn't do much for it structurally. I wouldn't necessarily use these settings for anything load-bearing, but when I'm just printing display models, they're great, and the models feel really solid. I also haven't yet broken anything printed with these settings while removing supports.

Anyway, just thought I'd share. Hopefully someone finds it useful.
