After doing some research on the different options, I began investigating a solution using Piwall (piwall.co.uk). Following their instructions, I have set up a two screen display using three Raspberry Pi's connected on a private network. Extending this to more screens will be simple as the software is easily configurable.
ok, since the 3D printer can't do the CEIT logo on the top of the case I've redesigned it to have the roof missing in the shape of the logo. I'm not so sure about the support structures for the letters, I still can't decide if it looks good or bad.ceit_raspberry_pi_case_top_correct_scale.stl
Just a small adjustment to the model for the top of the raspberry pi case.
I've finished a full draft of the case and battery pack with a method to attach them together. I didn't get to see if all the spacings of the raspberry pi case were correct because the printer was having some trouble, but from the one component that did print (albeit very warped), The spacing between some of the ports seems correct.
