It's the Roccat Vulcan Pro.
And while we're on the topic, thought to share (if allowed by the new rules, not sure) that I made a video on how I embedded that sensor panel of mine into my desk - it's in German, but YouTube has some great auto-translation. Not selling it or the design, don't worry. Just here to get and share ideas, so others can be inspired and inspire me.
And I sincerely hope, that spirit will continue in this forum & thread.
