I claim the ornamental design for a controller housing, as shown and described.
FIG. 1 is a top perspective view from above of the claimed design of a controller housing;
FIG. 2 is a right side view of the claimed design of FIG. 1;
FIG. 3 is a left side view of the claimed design of FIG. 1;
FIG. 4 is a front side view of the claimed design of FIG. 1;
FIG. 5 is a rear side view of the claimed design of FIG. 1;
FIG. 6 is a top side view of the claimed design of FIG. 1; and,
FIG. 7 is a bottom side view of the claimed design of FIG. 1.
The ornamental design which is claimed is shown in solid lines in the drawings. The broken lines in the drawings form no part of the claimed design. Broken lines formed by unequal length dashes (i.e., dash-dot) define bounds of the claimed design. The article is shown with a symbolic break in its length. The appearance of any portion of the article between the break lines forms no part of the claimed design.
