This is a basic filter cover for the Fluval Spec V all in one aquarium. The cover is designed to be printed simply and then placed on top of the filter utilizing the slot. This slot is just wide enough to accommodate for the filter wall, while also not being intrusive to the rest of the tank. There is a slot removed for cable management to the side of the tank. It is also accommodating to aftermarket lights. I recommend printing with the top flat face down as it will eliminate the need for supports.
