There's a couple YT creators I really like, one of them makes incredible products and sells them from the design side, the other one is running an large and automated print farm.

Two different angles on the problem, but both are using YT for at least some of their distribution problem. I'm not a big fan of 20 printers + flex-dragons sold on social media, since it feels like a low-skill hustle, but adding content creation seems like it could work. Thanks for pointing that out!
