The file 'Customizable Aquarium Lid Frame For 5.5 Gallons 3D Printer Model' is (stl) file type, size is 855.0B.
I needed a vented lid for my 5.5 gallon aquarium and couldn't find any that had openings for the lift tubes my under gravel filter uses, so I came up with this.
Instructions:
Print 6 of these, glue two pieces to each other with a mesh of your preference sandwiched between.
Leave whichever opening you need clear for your filter, lift tubes or airstone + tubing.
IMPORTANT:
This part is not designed for rimless tanks, I do not use those. You'll have to rescale for that and probably design some sort of lip to keep it from sliding off and dipping into the water.
In a standard 5.5 gallon, the plate will comfortably slot into the dip in the rim designed for a glass lid.
