The ornamental design for an appendageprotector, as shown and described.
FIG. 1 is a perspective view of an appendage protector, showing my new design in condition of use;
FIG. 2 is a top plan view of the appendage protector in an open position;
FIG. 3 is a front elevation view of the appendage protector; and,
FIG. 4 is a bottom plan view of the appendage protector similar to FIG. 2 in an open position.
The human form shown in broken lines in FIG. 1 is for the purpose of illustrating environment that forms no part of the claimed design. The broken line on the appendage protector represents claimed stitching.
