From Under the Sea Fridge Magnets

thingiverse

In keeping with the aquatic theme, here's some fridge magnets. A whale tail, shark fin, and I couldn't resist another octopus arm, they might work out nice as wall hooks as well. These should be scaled to fit a 12mm x 3mm magnet (with a wee bit of wiggle room), they might require some strong ones given the relative size of them.
