Case to house the Panel Due and 4.3" LCD. The "L" brackets are meant to be glued in place in case you decide to mount it differently than I have shown.
I printed mine with the face up so that I would get the nice printed surface but that meant that I had to print with supports. If you like the finish that your build plate leaves on your part then print face down and no supports are needed.
If you need the model for the 4.3" panel and Panel Due shown in the renders head over to my GrabCAD for the step files.
