My friend ground some sprues in his basement. The dust got into his air vents and now his whole house smells like plastic. He's kinda freaking out about it.
Have you ever noticed how many hobbies create a tiny mess that spreads way further than you planned? It's like glitter or sawdust. We get into something fun and don't think about the cleanup until it's too late. This happens with everything from sanding drywall to cutting foam. It feels like modern life is full of these small, invasive particles we're just supposed to deal with. The plastic dust is just the latest version of that.
