I claim the ornamental design for an oven corner, substantially as shown and described.
FIG. 1 is a top, front perspective view of an oven corner;
FIG. 2 is a front side view of an oven corner;
FIG. 3 is a back side view of an oven corner;
FIG. 4 is a right side view of an oven corner;
FIG. 5 is a left side view of an oven corner;
FIG. 6 is a top side view of an oven corner;
FIG. 7 is a bottom side view of an oven corner; and,
FIG. 8 is a top, front perspective view of an oven corner, the view showing the design of the oven corner within an oven.
The broken lines showing portions of the design in all figures is included for the purpose of illustrating environment and unclaimed features and forms not part of the claimed design. In FIGS. 1 through 7 of the oven corner is shown with a symbolic break in its length. The appearance of any portion of the oven corner between the break lines forms no part of the claimed design.
