I would like to briefly share my experiences. I first printed the tank with PETG from eSUN, using the normal settings. I have a P1S. Unfortunately, the tank was leaking afterwards. i put water in the tank and placed it on a towel for a few hours. the towel was wet. I had also printed a self-watering pot with elegoo Rapid PETG. This was also not leak-proof. So I assumed that it couldn't be the filament. I then put the elegoo Rapid PETG in the dryer for 8 hours (the eSUN was empty anyway). I increased the walls and bottom layer by 1. the new print then worked. i put water back in the tank overnight and placed the whole thing on a towel. the towel is still dry after 2 days! For the elegoo Rapid PETG I used the Bambulab PETG HF settings. Front door closed, top door/cover rised by maybe 1cm. i always just clamp something between the handle for opening and the housing of the printer. otherwise a great model and i'm already looking forward to giving it away.
