Clear tube support for window planter - 7/16"

Clear Tube support for Window planter. Compatible with 7/16" O.D clear tube which I used on a [WiFi-controlled plant watering system](http://www.thingiverse.com/thing:1677925).

* I've designed this clear tube support using [this window planter found at Lowes](http://www.lowes.com/pd/Garden-Treasures-23-75-in-x-6-in-Box/3915184). It may not fit some other planters. *Use it at your own risk*.
* 5/16" I.D x 7/16" O.D Clear Tube is perfect for those small **80GPH Aquarium water pumps** found on
