Hydroponic Fill Screen

*Update 2014-1-23: Noticed there was a small hole at the base of the screen, Fixed topology printing right now will post results.

This is a fill screen for this http://www.thingiverse.com/thing:210983 drain fitting by Vik. This keeps any growing medium like coco pellets or hydroton from clogging the drain and getting into your reservoir. If you like, I can make extensions that will allow you to print a complete ebb and flow adapter kit.
