Helicone ( Two types)

This is my latest work generated from a OpenJscad script.
You can make your own at :https://gitpharm01.github.io/designs/helicone/part1.html
I made a short tutorial video for it: https://youtu.be/3WLPjUSuZbM

Here's the demo for the 15 layer version on YouTube: https://youtu.be/GrstCvFnpjA

This time I made two different shapes on each side of the layers to make it more interesting.
All parts can be printed properly without using support.
Only the rod require several loos of brim to adhere on the printing platform.
