My first attempt at a container resembling a woodturning in Fusion 360.  It looks particularly good in the metallic silk PVA.  

I've included the gcode file I generated in Cura which has both parts together, with a skirt.  If setting your own parameters I recommend using a concentric fill, especially with metallic PVA.  I used a wall thickness of 1.4 mm.

It will print with no supports as the inside is shaped without any overhang.
