Can you get just one of these masses to oscillate?

Each of these masses is designed to have a different resonant frequency. Moving the base at different frequencies will cause different masses to oscillate.
I initially designed this as a class demo for an undergraduate Dynamic Systems class. Being able to shake the system by hand is a great way to understand frequency response.
I would recommend printing at full scale. As designed, the flexures are all .8 mm (two nozzle widths).
