Trouble with Slic3r calibration

The left is over-extrusion without doubt. Are you printing inner perimeters first or outer? Each perimeter will overlap the others so that you get good adhesion horizontally, so you might expect some pushing out if you're over-extruding a little. I'd try dropping the extrusion multiplier by 0.2mm incrementally on successive prints until you get a good wall.

In the solid cube ( the one on the left) there is only 1 perimeter.

What do you mean by dropping it by 0.2mm? The extrusion multiplier is either a factor or a percentage, not a distance. Can you please clarify?

Thanks.
