Origami Tessellation: Antimatter Chambers
This tessellation builds off the concept of using a small hex twist on bisected axes. A conventional hexagonal twist is turned on the axes that follow a triangle grid. However, you can also twist them offset from the grid. Doing this opens up new options with what shapes you can combine them with and how. In this case, I did rhombus twists around the hex. What happens next is pretty cool. We add open back hexagons off of the points of the rhombuses. Once you get that first set of central rhombuses in place, it's not too difficult from there. On the reverse side of the tessellations are the offset hex twists and some parallelograms. Crease pattern is included below.
