Stacking 4 Oscopes on top of a high shelf? are you serious? please reconsider, your work is worth reading.
What's the problem? Haven't you ever been in a lab before? The parts can be stacked and this is provided for by the manufacturer. Besides, everything's screwed down, don't worry. I need short signalling pathways to connect the scopes to each other, there are not many possibilities left. And - between you and me: when I'm standing in front of it, the top scope is barely at eye level. This is the art of photography, not a high shelf
If you don't have any problems, you can build your own...
