Fluval Flex Feeder Hole Cover (9 gallon)

Didn't like the models available online so I made my own. Easy to pick up and deters cats. Wanted it to be vented for airflow to prevent mold bring in fresh air. Also wanted a solid piece that didn't require supports. This was designed for the 9 gallon Fluval Flex might make some tweaks later but turned out great first try.
