This is an add-on bezel for the PiFinder V2. Its purpose is to simply fill in the gaps between the OLED and the front dress plate.

NOTE
A word of caution. These OLED displays have a somewhat fragile glass cover plate. Do not force the fit of this bezel so please check the fitment. You may need to do some trimming as the PiFinder build has somewhat variability where the display is located relative to the PCB/Front Bezel/UI Hat when soldered in.
