The ornamental design for a self-leveling laser level, as shown and described.
FIG. 1 is a top, front, right perspective view of a self-leveling laser level showing our new design.
FIG. 2 is a bottom, rear left perspective view thereof.
FIG. 3 is right side elevation view thereof.
FIG. 4 is a front elevation view thereof.
FIG. 5 is a left side elevation view thereof.
FIG. 6 is a rear elevation view thereof.
FIG. 7 is a top plan view thereof; and,
FIG. 8 is a bottom plan view thereof.
The broken lines in the figures illustrate portions of the self-leveling laser level that form no part of the claimed design. The stippling in the figures provides surface shading that merely clarifies contours of the surface and does not indicate surface texture, material, or color.
