Auto-watering flowers water tower from Gravity Falls

thingiverse

The Gravity Falls Water Tower is an ingenious creation that makes watering your flowers a hands-free task. To bring it to life inside, simply attach the opening lid, and then insert a water bottle into its hollow interior. For this clever system to work seamlessly, two essential conditions must be met: 1. All tubes must remain above the water level in the pot at all times. 2. The top tube that signals when water has reached its maximum level must be positioned directly above a tube where water flows freely.
