Once again I say thanks to Hyungsoo Kim who's posting on the Grasshopper forum provided the basic definition for this part. I added additional Grasshopper components, a top and bottom surface, and changed the geometry a bit and make the part 3D printable. My AAtom2 delta-style printer took a little over 24 hours to print this part at a layer height of 0.200 mm and print speed of 100 mm/sec.
Here's a short 3D rotation video showing the part: https://www.youtube.com/watch?v=VB9xIXqSA1A. The second photo shows the dish with tortellini, cashews, and dried apricots. Not the most appetizing combination, but it's what I had readily available.
