Automatic aquarium refiller

This is a automatic aquarium refiller designed to work with pet bottles. As the water level of the aquarium drops below the refiller it will refill the aquarium. its great for when you go on vacation or if you just don't like refilling your aquarium too often. you will need a rubber o-ring to make a proper seal. i recommend using asa/abs or petg. PLA will not work well.  The print orientation is also very important to insure strength. check the included print profile.
