This is a very simple bezel to mount a 1.3in OLED display to a panel. You cut a hole in the panel for the leads and drill four holes for the 2-56 mounting screws and sandwich the display between the panel and the bezel. The purple bezel was printed on a Ultimaker 3 and the blue on a Makerbot Replicator+
no idea - what was in the printer at work PLA
I used wet or dry sandpaper with water to get a smooth finish on the front of the bezel. I started with 320 grit and ended with 1500 grit.
