Small, functional Bluetooth speaker, consisting of a battery holder, amplifier, bluetooth module, and a speaker. No supports are needed for printing the box; however, a brim may be useful for the feet. I glued the speaker and the battery holder into the box using hot glue. The front is also glued to the main body. Links to the electronic components:

Speaker: i used an old 55m (8ohm 2w) speaker i had laying around.
You'll also need four M4 screws and nuts. Make sure to insert the nuts before gluing the front panel to the body.
