I tried printing in both PLA and ABS and the PLA is way better.
In general I used the default settings in Simplify3D for the "medium" quality print. I made these tweaks:
LAYER TAB: Top solid layers 4; Bottom solid layers 4; Outline/Perimeter 4; 1st layer height 100%, 1st layer width 100%, 1st layer speed 30%
INFILL TAB: external fill pattern - concentric
OTHER TAB: outline underspeed 50; solid infill underspeed 50; support structure underspeed 80
None!! Yay!! It prints all in one piece, spinning part and all.
