\begin{tabular}{lll}
Geometrical feature & Effect & Recommendation\\
\hline
Cube's size \texttt{d} & Increasing the cube's size increases the rotational stiffness & Should be make as large as possible\\
Strut length \texttt{L} & Changes the stiffness and coupling of the system (by changing the effect of the flexible joint bending stiffness) & Trade-off between higher stiffness and lower coupling\\
