Gaps in thin walls

Printing an object with a nozzle, which is only a few times smaller than the thickest wall, it might be that the slicer leaves a gap in the middle. For example: the wall is 1.5mm, and you are going to print with an extrusion width of 0.6mm, you need to advance some slicer settings for a solid print without gaps. For this reason, adjust the thin wall behaviour and/or the extrusion width in your slicer.
