Summary
This design showcases how a compliant parallel-guiding mechanism can behave identically to a rigid-body one while being made of a single uniform part. The attachment holes are sized to fit a standard LEGO technic pin.
Analysis of compliant mechanisms can be difficult due to nonlinearities in their behavior. Fortunately, a method of analysis developed by Dr. Larry Howell known as the Pseudo-Rigid-Body Model (PRBM) allows many compliant mechanisms to be treated like their rigid counterparts.
