I have a number of 3d files that I am trying to print on my printer, yet the problem i am facing is the normals inverting. I've tried various software to include MeshLab Maya (currently toying with) Netfabb Studio I need all the normals facing the same way in order for it to print properly, but whenever I try to reverse the normals, the opposite side then becomes the problem. I have tried the conform feature in MAYA as well and it still wont work. Can someone please show me how to get the normals to face all the same way, without the other side of the object becoming the issue as well? here is the files I am working with.
