This is a 3D printed Speaker that you can print at home. All you need is some enameled copper wire and a magnet! Parts have been printed with the LumiPocket 3D printer (http://www.indiegogo.com/projects/lumipocket-affordable-high-quality-3d-printer/)This is a good stress test for your printer since you will be printing the membrane itself and it is 0.1mm thick! A good resin-based 3d printer should handle this. Parts shown in the photo were printed with the LumiPocket, a compact and affordable 3d printer you can find on IndieGoGo!
