The ornamental design for a support for a desk, as shown and described.
FIG. 1 is a perspective view showing the rear, left side, and top of two supports for a desk showing my new design; and,
FIG. 2 is an enlarged perspective view of one such support for a desk.
The right side elevational view is a mirror image of the left side, and the front elevational view is a mirror image of the rear. The bottom view is not shown because it forms no part of the claimed design. The desk, brackets, and fasteners are shown in broken lines for illustrative purposes only and form no part of the claimed design.
The characteristic feature of the design resides in the application of a part having the appearance of an automotive shock absorber to the support for a desk.
