For something like this, PLA would be fine. If you wanted to be careful, you might get a food grade filament to make sure nothing nasty leaches into the water, but it would probably be fine in that aspect as well.
If PLA gets brittle with humidity, how would submerging it in water not make it brittle (faster)? Is there something about the hearing and cooling that changes the structure of PLA?
