In Cura I scaled to 90% to fit it; turned it upside down; switched off infill bottom; set bottom/top thickness to 2.4 (no idea if that will be enough);set layer height to .3 and print speed to 40mm/s (probably can go faster); set nozzle width to .8mm (ie use a .8 nozzle). Print time is shown as 7hr 23min. When you look inside the vase the bottom will no doubt be a mess. Looking at the bottom from the outside it will be fine once the bottom/top thickness is tuned.

Hi Warderoid, the object as it is won't fit my UM2 build plate in cura, some scaling down is needed for the model to "become blue" in Cura.
My suggestion, if you regularly have to print such large pieces, is to get the Olson Block and use a 0.6-0.8 nozzle. This will let you print much faster, at an higher layer height, without fear of underextrusion.
Otherwise you could try layer height 0.2, speed 40 for inner shell/outer shell/infill and see if your times get better. Then print at 220°C.
The problem is that you have some quite steep overhangs in the upper part of the model. Raising the temp or speed too much will not help quality.
However for such big pieces with relatively low details, a bigger nozzle is the real solution as it lets you keep the temp down while still achieving good speeds and layer height.
For the Olson Block see this thread:
