The ornamental design for a mechanical outputcomponent of a 3D printer kit, as shown and described.
FIG. 1 is a front elevational view of a mechanical output component of a 3D printer kit;
FIG. 2 is a rear elevational view of FIG. 1;
FIG. 3 is a left side view of FIG. 1;
FIG. 4 is a right side view of FIG. 1;
FIG. 5 is a bottom plan view of FIG. 1; and,
FIG. 6 is a perspective view of the mechanical output component of a 3D printer kit.
The broken lines shown in the figures illustrate portions of the mechanical output component of a 3D printer kit that form no part of the claimed design, except that the broken lines illustrating an electrical input component of the 3D printer kit and the connecting wires are environmental features which also do not form part of the claimed design.
