Aquarium Filter Box

This filter tank has an input pipe (diameter 11mm inner, 14mm outer) accepting water that is typically the output from another filter (ie Fluval). You then place water polishing medium (ie Purigen granules) in this box (do not fill more than half-full with granules), and it purifies the water before returning it to the tank. Works with a Fluval U1 underwater filter as the input. Detach the output spout they supply, and push fit this print in its place. The 3D printed filter box contains a number of internal baffles to maximise the filtration effect. Please consider giving this model a BoostBoost MeA boost costs you nothing to give, but both raises the profile of the model so others can find it too, and provides me with funds to help cover the costs of designing and improving models. Every boost is very much appreciated. Thank you! Fluval U1 filter (NOT the printed unit!)
