After thinking about the file I had created for an hour I decided to make one small modification. I created an eight sided post in the middle of the starburst. The eight sides would hold the LED lights and the post would support the top of the tree. I decided it would be simpler to route it as part of the original file than to build it later. The material was going to wast anyways.
Normally this is the kind of thing I think of far too late Maybe experience is making me wiser. We can only hope.
