Here's a simple mounting plate that attaches to the back of Justin's Google WiFi mount so it can be securely attached to a pole or any non-flat thing that a zip tie can reach around. The radius is 45mm which should work for most things, but here's the Fusion 360 model if you'd like to modify the radii for the pole and zip tie channels.

Print Instructions:

Default slicer settings. Dealers choice. Print with it oriented as modeled to get the best finish on the radius.

Parts List:

• (1) Pole Mount Adapter Plate
• (2) 4mm x 8mm Flat Screws
• (2) M4 Nuts
• (3) Zip ties

Assembly:

Attach the mounting plate to Justin's bracket using the (2) M4 screws and nuts. Slide (3) zip ties into the channels, wrap around thing and pull tight. Boom, mounted.
