Approximate project cost: <$20 Max print dimensions 120 x 80 x 80mm This little Bluetooth stereo speaker is super fun and easy to print and build! It has a much smaller print envelope than our first Bluetooth speaker project making it ideal for those smaller print beds. But don’t let its size fool you as it still packs a little punch! Features Bluetooth connectivity, an inbuilt FM radio, USB and SD card support, an inbuilt microphone for hands free talk and even a remote control! Powered by a single rechargeable lithium-ion battery you can take this unit anywhere, and your tunes will be pumping for hours! (Approximately 10 hrs playback).
