In short, I sure can't explain it well, especially with a language barrier. That being said, I recreated something close I guess, here's a pdf. Basically, make 3 long skinny triangles, offset them by 60 degrees, draw a symetrical hexagon over them, offset the hexagon flush to itself, find how much center moved, then do step and repeat functions to get the distribution you need for the hexagons.
You can take this pdf and just adjust line thickness to tune it to your liking... kinda
