Be careful with 3D printed parts in your plant system. You can't know what kind of additives are in there and what leeches into your plants.
I would never trust anything 3D printed in contact with food or plants that produce food.
Never mind that bacteria will accumulate in the layer lines easily.
I've started using sauce buckets from local snackbars as plant pots. As long as they're kept out of direct sunlight it should be safe long term.
This is shocking and unexpected. That sucks so hard, as I have just finished printing the tower. But I am very thankful, because without you, I would have probably ingested unhealthy chemicals. Thank you very much.
I will choose a PETG brand with a food safety certificate and avoid Creality PETG.
Edit: I also just learned that the hotend nozzle needs to be switched out, too. Brass contains lead, which is very unhealthy. Switching it out with Stainless Steel.
