What is the shape and degree of the beehive case?

1, the hive is like two pieces of paper filled with eggs, pieced together. One end of the honeycomb has a hexagonal opening, so the honeycomb chassis is designed for better ventilation.

2. All obtuse angles of the chassis rhombus composed of these beehives are designed as 109 28, and the angle can make the structure between chassis play a better role.
