the front end of Cura 2.x with UM2 does not allow you to change the nozzle size beyond 0.8mm, but you can tweak the "line width" settings. Also the temperature is not easy to change without making a bunch of filament setting in the UM2 firmware. So these files can help get you started on tweaking setting to print nice vases like my sine wave vase. I have shared my CURA 2.x profiles for vase with a bottom and vase without. Start with the vase setting before going to the vaseBase.
