Garden Drip Irrigation System – Version 2

A smarter, more refined solution for hands-free plant watering.
This upgraded drip irrigation device offers precise flow control, making it ideal for home potted plants, garden beds, greenhouses, and even balcony setups. Simply attach it to a standard plastic bottle (soda or water, 0.3L–2L), adjust the valve, and let your plants stay hydrated while you're away.

For proper functionality, do not over-tighten the bottle — allowing a bit of airflow keeps the water moving. If necessary, you can also poke a small hole in the base of the bottle to enhance air intake and water pressure. However, in most cases, just leaving the cap slightly loose does the trick.

Designed for convenience, efficiency, and peace of mind — this is Version 2 of our reliable drip irrigation tool, made for gardeners who like to keep it low-maintenance but effective.

Update: judging by the comments, it is better to update the support threshold to 20 from the existing 30, then after printing you will not have to dig out support from hard-to-reach places
