Sea Urchin Mouse Hat

If you have a salt water sea urchin and want them to look fly, give them a hat! Salt water sea urchins like to put things on top of their heads to feel safe, and you can add some flair to your aquarium by giving them cute little hats to wear! I used transparent PETG filament for my print. PETG filament is reef safe and does not float, so your urchin will be able to hold on to their new piece of flair and you won't have to worry about pollution or leeching from the plastic!
