Watering Tank Spike (Tested)

Model Overview

This is a functional, one-part automatic plant watering spike designed for easy printing and instant use. It allows users to upcycle standard plastic beverage bottles into a slow-release root irrigation system. Because it is printed as a single solid piece, there is zero risk of leaks or weak joints.

Key Design Features

• Integrated Universal Threads: The top collar features pre-modeled internal threads designed to fit standard plastic bottle caps (e.g., PCO 1810 / 28mm soda and water bottles).
• Reinforced Spike: A long, tapered conical stake that easily pierces into the soil, providing enough structural stability to support bottles up to 1.5 liters.
• Optimized Drip Holes: Features a vertical row of five precisely modeled 2mm holes. This size provides a steady, reliable water flow and is large enough to resist clogging from fine soil particles.

How to Use Guide

1. Prepare the Bottle: Fill a clean plastic beverage bottle with water.
2. Attach the Spike: Screw the 3D-printed watering spike firmly onto the bottle opening.
3. Insert Into Soil: Push the spike deep into the flower pot or garden soil next to your plant.
4. Create an Air Vent: Poke a tiny pinhole in the absolute bottom (now the top) of the plastic bottle. Crucial step: Without this vent hole, a vacuum will form and water will stop flowing!
