The mechanical components are the piezo apparatus (case and piezo caps) and the enclosure (for the BeagleBoard-xM and piezo drivers). All the parts in the images below, with the exception of the piezo elements, are 3D printed.
The piezo discs are mounted on the bottom part of the case (on the supports). The small tip of the piezo caps is glued on the center of piezo elements. The top of the case then goes over the whole thing and is secured by two 4-40 screws.

The enclosure shown here is designed to hold electrical components such as BeagleBoard-xM, the four piezo drivers (DRV8662EVM) and the custom made board.
