Bluetooth Speaker with a SURPRISING trick!
3D Print your own moduler Bluetooth Speaker with cool disco lighting and modular speaker design
At its core is the main speaker - everything is contained in the main box including the Lithium Ion batteries, recharging circuit, bluetooth receiver and amp. You'll also find both a standard USB and USB C port to re-charge your other devices.
This is where it gets cool though: Assemble the second 'slave' speaker for a louder system and it’s connected as simply as sitting it on-top. Magnets hold it in place and the Pogo pins form the electrical connection!
