Make sure your 3d printer is using food safe plastic.
I tend to advise people not to use 3d printer for this because it's cheaper just to buy food safe pipe instead

Using PETG. I believe it’s generally better for food contact compared to PLA. Worst case, I’ll plant flowers. 😜🌸
Coating it with a layer of epoxy will also work. Its food safe and you can even get brands that have been certified to prove it
