This is an 3D Printed universal DIY 12V Battery Pack. With the additional Bluetooth Amplifier board screwed on top, it becomes a great, very compact technical package for a speaker built. But it also can just be a Battery Pack for everything you can imagine. It is made out of 3 18650 Batteries which are connected in Series. The special thing about this Design is, that you can just exchange the Batteries when they lose their capacity or when they are broken. This wouldn’t be possible with soldered Batteries. This is an Open Source Project. You can download all the printing files from thingiverse and built your very own Battery Pack.
The Printing Files are for SLA (for example the Elegoo Mars) and FDM Printers.
