I designed this to fit a 1.5" OLED display into a 52mm gauge pod that I had laying around so I could add a small arduino-controlled info display to my car.

This fits a 1.5" OLED display. I purchased this one, but I am sure there are others with identical dimensions.

The display fits pretty securely because I printed with ABS and inserted the display before it completely cooled. I added a layer of tape over the back for extra security and mounted it in the pod with double-sided tape.
