I'm using my Gotek in an external case, so I wanted the screen to be on the top for better readability, I also decided to switch to using the Blackberry style trackball so put that on top too,
With both of those up there and the trackball also replacing the LED, I decided to restyle the base to take away the OLED and LED holes that I wouldn't be using.
The holes for the Blackberry trackball are lined up for the board that I bought from eBay

but I'm guessing most would be a similar size.
The OLED is sized for the 128x32 ones - which are a fairly standard size - it includes a small bracket to hold the oled in place.
It prints easy enough on my Eryone ER20 and that's a terrible printer so it should work for most people.
