Self-watering plant container spike for PET bottles

This print helps you feed water to your plants even when you away from home. 

By keeping some water in the tray, the soil will suck up water to the plant when needed. The PET bottle will then refill the tray when the water gets low enough to let air into the bottle. The bottle will stop refilling the tray automatically when the water level raises above the bottle opening.

Reusing PET bottles, like a Coca-Cola bottle, is a great way to maximize the utility our plastic resources.

I recommend printing the spike on the side for maximum strength, allthough it can be printet with the spike pointing upwards without problem too. 
No supports needed, but if you have problems with print not sticking to the bed put on a brim.

Here's a quick guide to how to use it.
