This isn’t just a mass produced speaker in a 3D printed case, but instead the speaker itself that has been 3D printed. Over complexity has been avoided to make a fun, simple, and sturdy little speaker. When connected to an Arduino, it pushes out a decent amount of volume and sound quality for its size. It can also play regular music with a proper driver.
Materials List:
Very thin magnet wire, 30+++ gauge — the resistance of the coil should be around 10Ω
Six 6×32 half-inch machine screws, two 6×32 nuts
Three 3×12 mm neodymium magnets
