In my current project, I'm using the boxed versions of certain operations. The amsmath package provides convenient \boxtimes and \boxplus operators for this, which are the same size as \square.
However, I haven't been able to find a box with a slash (i.e. set-minus symbol). Is there a straightforward way I could make one, e.g. by somehow removing one of the lines from \boxtimes, or overlaying \square with an equally-sized slash symbol? The straightforward \not\square looks rather dreadful:
. \cancel\square looks somewhat better, but the line still extends beyond the edges of the square:
