Nice! Fan of the movie here! I'll print this.
Actually it's not the mass, that counts. The ones with the hollow center have more moment of inertia for the Z axis so the will spin longer. Try to print them with thicker walls and no infill. ;)

I still run 13.03 most of the time. That version still uses skeinforge as the underlying slicer.
I recently installed 14.01 and I have been testing that. Sorry for the late reply. I haven't been on the site in a while.
