Aquarium lid hinge

Converting a top fin "awaken" half-moon aquarium to a terrarium for some dwarf geckos. This will keep them from escaping out of the hob cutout as well as gives an additional access hatch for feeding, cleaning, and other husbandry needs. The flat, back piece is attached to the aquarium lid permanently to give support, and the top flap will remain free to move. Not tested yet, YMMV.
