Here is an idea,
Go to your local cigar store and get an empty cigar case with plexiglass lid. Put your model in it and keep it clean, protected and the dust off. Also, I plan to do this, you can find pictures to match the model and past them to the back, sides, top and botton and have a small diorama.
On this one I plan to put a country background, sky above, a road on the bottom and disappearing on the two ends.
