I just published a new design to help mount the ST-V sound board, with requisite Darksoft Dark Knight multi, inside the Lions3 acrylic case. Hopefully this will help those of us that had the case and later upgraded to the newer multi and sound board consolidate everything into one nice package.

Just a note: I designed this considering the value of all the boards inside, and the weight of everything combined. With that said, I used aluminum standoffs instead of 3d printed standoffs, and the instructions will reflect that. My printer is an Ender 3 and I didn't trust the material, especially considering all the broken PLA toys constantly on my desk.. :) If anyone want's to remix and make a standoff pack for it, I'm all for that, it's just not for me. I'd be happy to help with some measurements as needed.

Additionally, to have a fully fleshed out solution, see my recent post about an integrated selector for the case, and the helper board used to make the sound board wiring, as well as fans have a nice place to plug without having to tap them from the board somewhere:
