Cage cube for water filter compatible with 5/16" I.D clear tube

This cage cube can be used to add a water filter to your irrigation system. It will fit a 5/16" I.D clear tube which I used on a [WiFi-controlled plant irrigation system](http://www.thingiverse.com/thing:1677925) connected to the Internet of Things.

* A water filter is highly recommended to avoid clogging the irrigation system.
* 5/16" I.D x 7/16" O.D Clear Tube is perfect for those small **80GPH Aquarium water pumps** found on [Amazon](https://www.amazon.com/dp/B01DVV8B78/ref=sr_1_6?ie=UTF8
