I claim the ornamental design for a mold swab testing tip, as shown and described.
FIG. 1 is a bottom perspective view of a mold swab testing tip, showing my new design;
FIG. 2 is an enlarged top perspective view thereof;
FIG. 3 is a left-side elevational view of FIG. 2;
FIG. 4 is a right-side elevational view of FIG. 2;
FIG. 5 is a front elevational view of FIG. 2, the rear elevational view being a mirror image thereof;
FIG. 6 is a top plan view of FIG. 2; and,
FIG. 7 is a bottom plan view of FIG. 2.
The broken lines showing a handle and mold swab in FIG. 1 illustrate environment of the mold swab testing tip and form no part of the claimed design. The broken lines shown on the claimed portion in FIG. 1 and the broken lines shown in FIGS. 3 and 4 illustrate portions of the mold swab testing tip that form no part of the claimed design.
