Thing is when you are publishing model on CGtrader you have to choose between "CGI models" and "3D print models".
But naturally many of these "CGI models" also can be printed.
So instead of two big separated categories there should be "Printable" option for publishers for ALL models.
Other thing is that majority of publishers probably don't know anything about printing and would abuse this option a lot even for non-printable stuff just to get more sales.
