Now that the camera is once again pointed at the 3D printers, it occurs to me that a very useful thing to have would be an indicator light of some kind on each printer giving some clue as to whether the printer is in use or not.
I think there is a plugin for Octoprint that can operate LED strips. That might work. Possibly with a manual switch to turn on a “broken” indicator. ( I think it would have to be manual. Or maybe an input into the same plugin could be used to signal something other than “running”, “idle”, or “out of filament”.
I haven’t got either of my printers up to the point of actually needing OctoPrint yet, so I haven’t explored the lighting options myself. I’d bet someone in thge group has though.
