ffleurey modeled this awesome Gravitrax element and shared it on Thingiverse so other 3D printer owners can print it out:

Unfortunately, ffleurey does not explain how he built the electrical circuit. Since the recommended solenoid threatens to die at higher voltages, and it has not enough force at the specified voltage, I designed a simple circuit that solves this problem.
