Once everything is working, add your external enclosure, and optionally hot/super-glue some tripod mounts to the case edges. I printed them in black PET at the fastest draftest possible settings which still took 3+ hours – the caveat was the enclosure holes were less than great, which is something I can live with, print yours in PLA at finer detail if you want a nice perfect case.
The lid mounts with any thin screws you may find in your junk box. I ended up adding a little hot glue to the edges to ensure a solid bond between the case and the display:
Enjoy your new portable display!
