This speaker box is designed for a 50mm speaker, 4 vape batteries, and a Bluetooth amp. Magnets hold everything together. Please remix and tweak it to your needs. I put some foam from the packaging of my print in the box to help with the box vibrating. Makes a slight difference.

Makes for a nice speaker while working.

The speaker is glued in place and the batteries are held and charged in side the box. There is a micro usb to power the speaker and/or charge the batteries.
