Urchin Hats

Urchin Hats are a goofy little 3D printed accessory made for saltwater urchins. Just place the hat on top of the urchin and it will usually grab it and carry it around the tank for a while.

Urchins naturally like to hold things for cover and camouflage, so this is a fun way to lean into that behavior while adding a silly prop to your aquarium. It also makes it a lot easier to spot where your urchin is.

How to Use

  • Gently place the hat on top of the urchin until it grabs it.
  • Let the urchin carry it around the tank.
  • If it drops the hat later, just place it back on again.

Important Notes

  • This is a novelty accessory made for fun.
  • Some urchins will hold it longer than others.
  • Because this is a 3D printed part, minor surface texture or visual variation may be present and does not affect normal use.
