Google Nest Wifi Router or Point Wall Mount. This is for the 2nd gen (released in 2019, rounded edges, and branded as Nest Wifi).
The shape and cable arrangement is designed to fit both of the devices. The point will have a little extra room so if you want it to be super sturdy put in a piece of sticky tape on the back, but it should hold just fine without.
This is a new and improved design from my previous one.
