12V Outlet Bezel

The dash on my Kawasaki Teryx has a "knockout" for a 12V outlet to be installed. I cut out the hole in the dash per the knockout...but I had not checked the actual diameter of the usb/voltmeter that I assumed was the same size as a 12V outlet.
The hole was too big for my usb/voltmeter, so I made up a quick bezel for the front and back. The front one has a slight bevel to it.
Holes are 29mm, with a 50mm outside dimension. I think 5 or 6mm thick for the front, and 4 for the rear.

Works fine, and looks like it was made for it.:)
