About this 3D model

I created this music visualizer box as a birthday present for my friend. This project is based on another DIY project where a led strip was mounted on the wall to visualize the music https://www.youtube.com/watch?v=2ilgsEC2wig&t=1s&ab_channel=AlexGyver . I've modified the project to fit into the box and be powered by the battery. The main changes to the original project are: I've changed the Arduino code so the LEDs light up correctly; I've added battery using the power bank electronic plate I bought online and some battery cells from Aliexpress. For assembly, I've used m3 bolts and threaded inserts. The lid part is glued to the top part.
