Putting it all together took a bit of trial and error. The original build didn’t take into account that the screen wouldn’t center on the Pi, but would be more offset than expected. To accommodate, I ended up making the left size open by one block width to make room for the ribbon side of the monitor. I also had the power running externally, but shifting the display over inside allowed me to use 90-degree adapters to run the power cable internally. For sound, I’m currently running off a 3.5mm cable that can be accessed in the back. In the future, I might dismantle the current speaker housing and slip the speaker inside between the Pi case and battery for a cleaner build.
