January 12 & 16

I did a little work on the Grasshopper definition for the Twisted Bead. This is a little more suitable for making vases. Just draw the driving curves, move the base point to control scale, and set the amount of twist and the number of surface texture repeats. I usually work in Rhino to tweak the form generated by the Grasshopper definition. The CageEdit command is good to adjust the overall form quickly. That's how I shaped the elliptical opening at the top.

The STL is meant to be sliced with "spiral vase" mode (or just omit infill and top layers).
