I've installed the "Extra Objects" addon in blender a while ago and didn't pay it much attention - but yesterday I played with the meshes and immediately fell in love with the honeycomb mesh since I really like hexagonal structures - I extruded it with the "Solidify"-Modifier and twisted it around with the help of an empty and the "Simple Deform"-Modifier.
