I have a PCB designed but still want to improve it so I won't be sending the order in yet but this is more or less how it will look like. I wanted to add USB C but I already have a long micro USB cable I use with my current version so it will just be easier to use micro USB. The space inside the enclosure is quite tight for anything tall like the female header. Some right-angle headers might help so I can easily disconnect the neopixels from the board.
