printing a single walled object

[ml3dprints]

Is there a certain setting to print a single walled object? I can't see a print preview for this, and therefore it won't print the object. I have a .4mm nozzle and default extrusion width set.

I think I found my answer viewtopic.php?f=9&t=57.

I will try that.
