Epicyclic3-4

This design is a modification to https://cults3d.com/en/3d-model/home/epicycloid3-1. I did like that design and wanted to try it out on something larger, but when I did that I was not happy with how the results looked. So I decided to use an old trick of combining forward and reverse twists to the basic shape, and this is the result. Because there are so many small printhead moves this version takes a long time to print. That's what happens with lots of small detail.
