Supports are needed per the original model. This is for someone who needs their Eero 6 Pro mounted to the left (or the right if you flip it in your slicer) of their vertical wall socket, as opposed to the original, which had only a horizontal socket. This is for a socket that only has one screw in the center.
The author remixed this model.
I've added a cord wrangler and a single screw socket. Supports are needed per the original model.
