Hi There, I'm absolutely new and am starting to learn. I've used cura a little and have printed basic parts. But now I'm trying to design my own RC Plane, and am having problems. I need help solving why I have missing layers. I've tried increasing the size of my object but I keep having the same missing walls. Can someone help me or direct me to what I need to do next to problem solve this. I've looked at various forum topics on missing layers but none seem to help me.
I've attached the .stl file and pictures from Cura.
I really appreciate any help or direction on this.
