I feel like im stymieing myself ive seen some great models on this site but when i do them they some come out with a really stepped edge. this is my current STL export setting it could be improved but i dont know where to start.
From your photo, it looks like you have a slight curve to the surface of your model and that is resulting in stepping. To prevent the stepping, either remove the curve and make it flat, or make the curve more pronounced. increasing the triangle count won't help.3D Printing Engineer | Shapeways
