Rusty first aid box made out of an old mints case.
Cut down to size, kept the lid so it could be opened. Removed the base and glued it into the new box.
Sliced the outer plastic off a small electrical wire and used it to cover where I'd cut the tin and to also hold the base in.
Then painted with brushes. The white '+' symbol is cut out of some waste decal vinyl.
im sure its been done but have not seen it. I just printed a road map that i shrunk down and folded like a map i now have a scale road map of my region"thumbsup"
