<p>The wall thickness is 1,2mm but the lip is only 0,6mm thick. How will the 0,4mm nozzle solve this?</p>

<p>Alternatively I could choose a 0,8 mm thick lip, but then the connecting end should be 0,4mm that is too thin. </p>

Nozzle diameter is almost always less than extrusion width.

I'd say you should experiment with [Slic3r](http://slic3r.org/)

it can manage extrusion in very sophisticated way

it can overextrude if you need a line wider than actual nozzle size
as same as it can underextrude if needed
it can even change extrusion continuously while extruding one line

here are simple examples

i use [mattercontrol](http://www.mattercontrol.com/)

take a look here - this is the same object the same layer and the same settings

**please notice - this object has wall thicknes exactly 2 times nozzle diam**

here is what i get with

* native MatterControl slicer engine which gives this slice
