3-way Irrigation Plant Spike for Mini Pump (5/16" / 8mm)

thingiverse

This is the watering spike I use for my solar powered ESP32 automated irrigation system. It is designed to work with 5/16" or 8mm tubing and a small DC water pump. It provides even water distribution across many spikes. Single line or in a loop. When the spike's small reservoir fills, the water passes more easily to fill the next in the loop. This isn't a sprinkler. It is to be used in a slow process of watering, waiting, and sensing moisture. There are many ways to configure the loop and vary depending on one's desired setup. The air intake piece can be used with spikes you want to be filled first. Lesser resistance = more water there. Print in less than 0.2mm layer height with cooling, no supports needed.
