Surface skimming overflow box and plug for Imagitarium Pro Deluxe 3.7G AIO Cube

A surface skimming overflow box and a plug for the lower hole in an Imagitarium Pro Deluxe 3.7 gallon AIO cube aquarium. The overflow box includes an outer set of teeth to retain a small piece of screen, in the case you need to keep small animals (in my case fish larvae) from going over into the rear chamber.

Version 1.1 update: made the fingers a little taller and changed the geometry/angle between the clip to better seal on the bottom side of the overflow box. This helps especially with low flow pumps like the stock one.
