Just a quick update. The project is working as expected and living under my desk (see pics below). I definitely should have added a power and reset switch to the design, but other than that I’m happy with how it turned out. The code can easily be tweaked if the 6 defaults I created aren't to your liking. 

Eventually I’ll add step by step instructions to repeat the design, and I'll push a 3D model for a case. No guarantees on a timeline for this, as its low on my priority list now. Feel free to drop a comment though if you’re waiting on the files to recreate the widget... if there’s some interest, I can push it out sooner.
