I couldn't find a simple mount for the .96 OLED screen that I had.
The spacing of the mounting holes is 23.25mm by 23.25mm.
I think that it is overkill to bolt the OLED screen onto a case.
I wanted really simple.
I needed to put it onto a case that also holds an ESP8266 and another case that holds an ESP32.
With this I put a 29mm by 29mm hole in the case in Tinkercad and placed this mount into the hole.
To hold the OLED screen in place I used the tip of a soldering iron and melted the pins down to hold the screen.
In another case I cut a small piece of the foam that protects the pins on an ESP8266 during shipping and put the foam between the back of the OLED and the ESP8266 board and screwed the back of the case on.
And I have included a picture of a case with an ESP8266 and the screen is taped down.
