I printed it on my Replicator in ABS using your settings and it did fine when I removed the supports. I did use an exacto knife to help it along and to carve out some of the star shapes, they went a little funky on me. I'm going to try it again tomorrow with a smaller layer height (and different color). Any speed suggestions? I was thinking of slowing it down a bit. I also might make some ABS glueÂ andÂ fill in the bottom ridges. I haven't had my machine for very long so I am still learning!

200_stars_with_support.stl solved the problem; the support is built into the file. After printing the support material is easily removed by pulling at the corners of the structure so as to peel it off the sphere.
The ornament is meant to be printed on a raft. I printed it on a Replicator with 3 shells and 10 per cent infill. Because of the large number of holes. and as the walls are only 1.5 mm thick, the ornament is essentially solid. The ornaments are 70 mm in diameter and weigh approximately 16 grams.
The openSCAD code takes hours to execute on my machine and the printing time for the ornament with support is about 3 hours. The support structure ensures that the base of the sphere has a nice finish.
