I needed to switch lanes on the Multiboard on a tight space. Sharp turns weren't an option due to cable thickness and the curved Channels needed too much space. So I modeld these channel with a footprint of 2x2 and 3x3 as you can see an the picture. 

The 3x3 one works fine with only two of the mounts. But the middle one can be helpful, if you need to align one opening over the edge of the grid.

As Base Grid you'll need the Multiboard Grid:

To connect it, you'll need at least one of the Standard Underware Connectors:
