I agree with you totally about the market research... as a seller, without it there is basically no point in trying to build anything because unless there is a market for it it won't sell.
Fact is even outrageously poorly designed stuff can sell if there is a market for it but it is so hard to find out what those buyers are truly after... I guess the everyday small time modelers like us will never know.
I just wish there was a way we could get CGtrader to sell 3D goods at places like Walmart by partnering with them. Think about it. 3D artists could make small time custom 3D prints for kids based on their favorite toys.
Online 3D is just too small a market but Toys that people can buy where they shop every day and require 3D artists to make them would really make a huge difference in earnings. That would be the way to make a fortune but I have no idea how one would go about introducing something like that...
I have been wanting to get into that for years but I just don't have the financial resources or connections to get it up and running.
Basically we could bring custom 3D printable toys to Walmart or shopping malls. One could even partner with the Apple or Microsoft stores too who already have clients interested in 3D.
