This is a can holder I made to fit within the Gridfinity system. It is deeper than the others I had found and has an internal can contour. There is a small hole at the bottom so even if the can is sweating it won't stick to the bottom. The idea of it being so beefy was to give it a bit of insulation in lieu of a koozie.
