Surprisingly good approximation of single gyroid made from overlapping equal-handed helices

Here’s a neat little construction of the single gyroid as the union of perpendicular overlapping helices. All are equal-handed, clearly emphasizing the chiral nature of the single gyroid.

Feel free to use, but please give credit to the following work (where this construction is described in the appendix).
