Twisted polygon Vase mode container

After someone posted in a Thingiverse forum for my printer asking about the "spiralize outer contour" function I became curious. I made this design and printed it. After a significant amount of figuring I got the dimensions to work so the top and bottom screw together. The top needs to be about 1.5 to 2 mm larger than the bottom. In vase mode a bottom layer is printed and it prints a single wall, no matter the design.
