Hemi-demi-sphere with corner support tabs
thingiverse
I'm trying to print VeryWetPaint's interlocking sphere with PLA and I'm having trouble with two sharp points on the base curling up, which is preventing everything from fitting together properly. This version includes tabs on the corners to help improve bed adhesion significantly. After printing, the tabs are easy to break off cleanly. My print settings were 0% infill, 2 perimeter layers only, and I skipped using a raft altogether. Simplify3D sliced the tabs perfectly - they're separate bodies but are close enough to stick together with the main part.
