I bought the Google WiFi Mesh routers for my home but, in order to spread them out properly in the house, I had to create a wall mounted holder.
With it, you can have them in any wall, as long as you have a power outlet/socket around.
The 3D printing should not need any supports, but it might be good to add them to the bottom of the round “neck”, as it's diameter is considerably big and it still under 45 degrees.
The author marked this model as their own original creation.
