Decided to house the screen and PI in a case so dusted off the 3D printer and this is the first draft.
Repositioned the PI to the edge of the base so the phono and power sockets face backwards.
Network and USB ports on the left.
Bought a cable to go from the PI to the screen but turns out the screen is not using the standard format so 'tweaked' the cable I bought and now all is good as can be seen below:
Will design a new case which will allow me to easily add sides and back.
