This is version 2 of the GMA 1347 Audio Panel.
 
It's a step up in aesthetics, combining a detailed 3D printed shaped body into which a laser etched panel fits. The buttons also have etched faceplates in this version for a more detailed and professional finish. All parts are backlightable.
 
This design is available with resin 3D printed Button Cases that guarantee that the laser-etched button faceplates and the LED tactile switches fit. This should help avoid the many people who struggled with their printer calibration. With these buttons also being resin printed, they come out smooth, which helps in the operation by ensuring the layer line ridges do not interfere with the close tolerance parts.
