Water Changer Adapter for Aqueon/Python Water Changers for aquarium. I actually haven't tested this with a python system but I am pretty sure they are the same threads, so If you have any problems let me know! It is essentially a male GHT (Garden Hose Thread) to a male 13/16-27 adapter for your sink. If your sink doesn't fit the adapters included with the Python/Aqueon kits and you have tried all of the adapters, this might work for you! If you don't know your faucet dimensions, you may as well print it and test it out anyway, it's only 5 grams of filament and about an hour to print. Make sure to read all print settings and notes!
