You sound like a wannabe grandpa “When are my grandkids coming dear, I want to see them before I pass”

Blud actually pulled Correlation doesn’t imply causation out.

Toy production, I have one - the main use is making whatever toys I think are cool. You want more LEGO - 3D print it. You want something to throw something for your dog, 3D print it.

Admittedly those aren’t use cases so much as hobbies. Occasionally you can 3D print a repair for a curtain hook or something. But everyone likes toys, even adults.
