This is actually a test part I made to check out some geometry I adapted from an Italian jewelry maker. He created a Grasshopper layout to make bracelets based on twisted Voronoi patterns. I helped him get his layout working and then combined some of it with some vase geometry of mine to make this part.

Since it is full of holes I don't think this part is particularly useful. But it looks rather cool so I thought I'd post it. This one prints in about 4 hours @ 0.200 mm layer height. I'm thinking about making a larger one, and perhaps add the inside surface to make a solid part that could hold something.
