I have a Jewel Vision 180 aquarium which has a large rectangular cutout for feeding the fish. This unfortunately doesn't allow my automatic fish feeder to attach anywhere. Its just precariously balanced on the edge.
It also presents a fairly large opening for fish to splash or snails to escape!
This thing fits the hole with a small overlap on top to keep moisture out and presents an attachment for the feeder to screw onto. It also has a funnel inside so a smaller opening is open to the tank.
Jet Black / Tangy Orange
Using the settings, the supports just pulled straight off. No other post printing was required.
