I printed this model in Polymaker PETG, i printed Martins Hydroponic tower but could not find a suitable plant cup that i like, this was just for fun, no special print profile needed use your own judgement, the holes are small and they work well, I used panty hose to line the cups with so i could fill with dirt, feel free to let me know what you think, I am not in competition and i am still learning but i printed a bunch of these and they all came out great.
