4x4x4 PL9823 LED Cube Base

This is a base/case that I designed for my 4x4x4 PL9823 RGB Cube. The cube itself is mounted on a 10cm x 15cm protoboard and this base is designed around that.
This was created in Tinkercad, so if you need to make changes you can grab a copy there: https://www.tinkercad.com/things/9YMhCBPISxb
As far as the build, there are a few good PL9823 RGB Cube builds over on YouTube and instructables, so I won't reproduce their work. LED's and Protoboard came from Amazon:
Protoboard - https://www.amazon.com/gp/product/B06ZYZMM3H

The microphone came from Adafruit: https://www.adafruit.com/product/1063
The project runs on a Arduino Mega, for now it's running the latest VU Meter code from Cine-Lights channel on Youtube: https://www.youtube.com/channel/UCOG6Bi2kvpDa1c8gHWZI5CQ/feed - be sure to check it out, great inspiration there. There's also a build video in the feed for a cube like this one, if you need s
