Bowl (vase mode) simple Freecad design

When looking for bowls, I could not find any that are meant to be printed in vase mode (model must have closed top). 
 

After pushing my printer to its limits with cura and spiralize outer contour, I found that I was able to print 3mm wide and 1mm tall with a stock 0.4mm nozzle setup. 

This creates strong parts with minimal artifacts, and decent speed.

Settings:

Layer height: 0.8mm

Layer width: 2.4mm

Spiralize outer contour:yes

Bottom layers: 3 (for equal thickness of walls and bottom)

Speed: 15mm/s (extruder should not skip)

Increase nozzle temp when at higher speeds.
