Splitters and Mergers can be stacked and belts can be connected above them.
With Splitters this works completely fine but the Visible Model of the Mergers is slightly higher. This results in the Merger clipping through a belt placed above it (using stacket splitters / mergers or 1 high poles).
Placing two Mergers on top of each other and looking at them from the side results in them clipping into each other.
I think the Mergers should not have clipping when placed above each other and belts on top of Mergers should not clip into the merger.
PS: This is only visual, functionally it all works
