Watering connector for PET bottles.
new version release 2019/6/30:
The original design, when pouring water into the bottle, is easy to overflow and can only be added slowly. Because the air in the bottle creates resistance. The new design has an air duct that is subtly hidden in the handle for smooth water injection. please download the second file, v2.
