I claim the ornamental design for a faucet, as shown and described.
FIG. 1 is a perspective view of the claimed design;
FIG. 2 is a side view of the design of FIG. 1;
FIG. 3 is another side view of the design of FIG. 1;
FIG. 4 is a front view of the design of FIG. 1;
FIG. 5 is a rear view of the design of FIG. 1;
FIG. 6 is a top view of the design of FIG. 1; and,
FIG. 7 is a bottom view of the design of FIG. 1.
The ornamental design which is claimed is shown in solid lines in the drawings. The broken lines in the drawings are for illustrative purposes only and form no part of the claimed design. Broken lines formed of unequal length dashes (i.e., dash-dot) define bounds of the claimed design.
