improve the edges
I tried to print a cube but as you can see the edges are not sharp. I'm printing with Kossel Mini & Simplify3D I left the default values for the configuration Kossel Mini. Medium resolution Pla 1.75 Nozzle 0.4 Extruder Wade Bowden. You can do something in the settings of Simplicy3D to obtain sharper edges? Thank you
Re: improve the edges
Get a smaller nozzle 
The edges are going to have the same radius as your nozzle, so there's not much you can do to avoid that.
