Abstract: Embodiments herein are directed to a portable diagnostic tool. The portable diagnostic tool includes a tool body, a first hexagonal shape, a second hexagonal shape, and a plurality of legs. The tool body has four peripheral edges, a top face and a bottom face positioned on an opposite side of the tool body. The first and second hexagonal shapes are disposed within the tool body extending through the top face and the bottom face. The second hexagonal shape is larger than the first hexagonal shape. Each of the plurality of legs extend from the same one of the four peripheral edges. Each of the plurality of legs are spaced apart and extend an equal length. Each one of the plurality of legs has a first surface and a second surface. The second surface has a tapered portion with respect to the first surface.
