Your wall thickness is .18mm. This is too low. Zortrax will not slice (the process of converting a 3d model into layers for the printer to understand) anything below .5mm.
Learning to increase wall thickness is fairly easy once you start to learn your software of choice.
I recommend you start with something like Sketchup, which is free. The tape measure tool will tell you how thick your walls are, you need to work on making them at least .5mm. Youtube is the best place to go for tutorials.
