This is a more complex iteration of the EspDeck in order to allow control of multi room audio systems (or anything else you want to use it for). There are two top panel iterations, one for 9 mechanical key switches, and one for 8 key switches and one rotary encoder. When printing, use one top or the other for your build. The top plate should be printed with at least a 0.16mm layer height. This helps with the home assistant logo printing cleanly. If you want a multi color print, swap filaments on the second layer, that way the background of the logo will be the second color. Source files and schematics can be found on GitHub.

I wrote a blog post on my design process and assembly of it as well here.
