This is an abstract shape that reminds me of driftwood, especially because the "grain" of the model adds to the design. With multiple view ports, it's interesting to see the ball in different positions.
For one print, I used an oil based paint marker to paint the ball black.
UPDATE: I added a version I printed with black PLA, sanded, spray painted black and then painted the ball with gold. It reminds me of Japanese lacquerware.
I used ReplicatorG on my MakerBot Replicator2 with the Replicator 2 slicing defaults and the following settings with white MB PLA:
Infill = 10%
Layer Height = 0.200
Shells = 1
Feedrate = 40
Travel Feed = 55
Temperature = 220
