Innovative Marine Water Riser

Not even really sure what to call this, water riser, overflow gate, display riser, etc... Anyways, This keys into your overflow on your innovative marine nano tank which causes the water to rise in your display tank to a higher level. I was unhappy with the height of water in my Fusion 30L so I decided to make this and raise the water level to a more "aesthetically pleasing" height. I'm unsure if this will key into other size overflows, so if you print this for yours and it works let me know so I can add update the post.

Confirmed:
