Realistically speaking, what are some ways to make money with a 3d printer?
lve seen people on ebay and etsy sell ps4/ xbox controller racing accessories, mailbox flags, and COVID 19 respirator shit but most of those ideas are already taken.
It's not like l can pull any random thing off 3d printing websites like thingiverse, print them, and sell them as my own because most of that stuff is under a creative commons license. So the best thing to do is to come up with something completely original within solidworks or something like that.
What would be something that your average CONSOOMER would buy that normally isn't available and would appeal to them?
