I am looking for a feature which creates a border for the top layers. To explain, sometimes when there is another object that is higher than the main infill and the top layers start to print, the top layer creates the border for that object. What happens in reality is that if the infill is low (the lower the worst it become), it has no edge to catch the filament to, and it just "falls" leaning on the infill wherever it is. This can be fixed if the slicer will add a perimeter that the filament will be able to "catch" when extruding.
Is there anywhere an option for that ?
