The situation:
During ore production I've got 2 sets of 8 belts coming at each other orthogonally. All 16 belts will have the same ore on (the different ones are just for illustrative purposes.) Typically only one set of 8 will be active. The original layout was 11x9 squares but I needed 2 squares more to fit something else in so I moved the next step one further away and spent some time shrinking this one square to be 10 across by 9 high. AKA one wider than the belt lanes intersection on three sides.
What is does:
One belt is taken from the right side, one is taken from the bottom, then merged with a splitter and output onto one belt going left. This doesn't do any balancing just takes whatever is coming from two different directions and sends it away.
My Opinion:
Is it pretty? No. Does it work? Yes.
If it's useful it's here, if you do something better; post it!
