I’ve made and shared plenty of 3d models for the 3D printing community. People can certainly make it a job, and that’s perfectly reasonable. But, I will never be interested in a community of for-profit model makers. If their goal is to make money off me, it’s not a community, I’m just a customer. The point of the community is to learn and share information, to help people and be helped in return. If that time is ‘work’ for you, don’t do it. Or make content and sell it on YouTube, do what you want, I’m just not interested in it.
