Blueprint - 1x1 Omni-Directional Stacker

This Stacker Platform takes input from 3 sides and puts the output out the fourth. It does not matter wich side is chosen as input. Layer 1 always goes to the bottom and Layer 2 always to the top. Also Channel Number stays the same. If you input the left most Channel in Layer 1, it will be stacked together with left Channel from Layer 2 from any side, does not matter. But never with input from another Channel of any side. There is also enough space at the output to change the Layer.
