Hemi-demi-sphere with corner support tabs

In trying to print VeryWetPaint's interlocking sphere with PLA, I was having trouble with two sharp points of the base curling up, preventing everything from fitting together. This version includes tabs on the corners to help with bed adhesion. After the print, the tabs are easy to break off.

My print settings were 0% infill, 2 perimeter layers, no raft. Simplify3D sliced the tabs nicely - they are separate bodies, but are close enough to stick to the main part.
