About this 3D model

This is a fluidic amplifier from this [patent](http://www.google.com/patents/US3666273). It should have a pretty nice frequency response as it is intended to be used a part of a sound amplifier circuit for a gramophone. If you make several other amplifiers according to the sizes in the patent and wire them up according to the patent, you sould be able to make a completely fluidic acoustic amplifier. Specifications derived from patent: Nozzle size is 0.02" x 0.016" and operating supply pressure is 0.5 PSI. NOTE: this thing is tiny!
