Do the prints slowly release microplastics into the water that kill the urchins?
- If they used PLA(made of cornstarch) which is common for fdm 3d printing then theres no threat of microplastics from what ive read. it is biodegradable, but very slowly.
  
  Makes sense. People that are serious about fish tanks don't mess around
  
  I doubt it's 100% cornsarch. I work in the plastics industry and there's all sorts of travesties going on. We also have a line of cornstarch-made products, but they're all scams when it comes to "recycling" and "being biodegradable".
  There's definitely plastic in it.
  
  From what I've read PLA is only biodegradable under very specific conditions. I looked into it and you have to send it to a recycling center designed for PLA and its expensive to do so. I would assume microplastics would still be present too. Even though it can be sourced from plant matter its still plastic.
- About the same level of concern that feeding your dog dry food is. If not even smaller.
  
  But how can I push an agenda if it doesn't?
- Of course, for that is the way of things

There's something terrifying about a sea urchin wearing a hat slowly approaching you.

- At any point in time there is an urchin getting closer to you
  
  But it's distance to you is not monotonic so it's alllll goooood.
- Scale it up and it's a Dark Souls boss

In Stardew Valley, you can put hats on sea urchins if you put them in an aquarium.
