Do not put it into high-temperature liquids, otherwise the PLA will melt
Don't put boiling things in it if the PLA melts.

When printing, I suggest setting the wall thickness to 2mm, the infill density to 80%, and the print accuracy to 1mm, 2mm, or 3mm
You can set it according to your preferences

For printing, I recommend a density of 80 for 100 walls of 2 mm, with a printing fineness of 1 mm, 2 mm, or 3 mm.
Do as you please.
