This is a 2x1 Gridfinity baseplate designed to hang on the side of an aquarium. I wanted an easy solution to hold my fish food so I adapted a simple 2x1 baseplate, so this will interface with any Grifinity bin/holder than can fit in that footprint. The clearance for the hanger is 8mm, so any glass 8mm or thicker will be unlikely to fit.

This most recent version is designed to no longer need any support material, but this results in it being shorter. I may make another further revision that is "taller" that has a lower center of mass when hanging over the side so the the Gridfinity bins don't sit taller than the edge of the tank.
