Chade. start cutting off those triangle tabs, and glue a strip just wind enough behind the piece, the other wise, after first side dries, can then be glued to that flat surface sticking out. on the nozzles would have been able to form them into perfectly shape cones, and the seem would be virtually invisible. As the parts get bigger,, this misalignment gets more pronounced, and the problem of white edging appears. By cutting out the tabs, and using the strip method, the surface are on the same plane, and you have no white edges, if you are careful, and have cut the parts perfectly,
the seams disappear, and turn into panel lines. I suggest giving it a try. It will take your models to the next level!
