gcode file different from the stl file (cura 15.04.6)

Hi,

At the end of printing with my Ultimaker 2, I got a box full with PLA: the gcode file does not match the stl file.

Please see attached zip file (the zip file include stl and gcode files)

I don't understand why.

Thanks for answer.

Some faces of your mesh are inside-out. This causes Cura to be confused what the inside of your model is and what the outside is. I've fixed the model for you in Blender.

Thanks for answer,

I don't understand how I create the problem: in sketchup, I made an empty box (like a soap box), then I drill holes, then I cut the box (the role of the box is to contain a PCB). One piece was OK in Cura, and the other one, no, although the two sides appear correct in the stl files.

The problem is sketchup, it's very bad for 3D modeling physical models. Because it does not keep a proper representation of what is "inside" and what is "outside". Causing Cura to be confused.
