It seems that I finally cracked it. My adjustable honeycomb should fit all bees. (100% parametric)
The idea is that basic parameter values can be set in a spreadsheet (like element radius, wall between elements, number of rows and columns).
Although provided here for hexagons as a primary shape, the approach can be useful for circles, and other shapes as well. In this manner pipe bundles for heat exchangers could be designed.
Suggestions for improvement are most welcome.
