Great work! It 'obvious that the horizontal joint cannot function to keep suspended an adjacent panel. In fact, not yet available to the last Minori’s post, the joint was simply designed to not allow the movement of the panels on the x-y plane. However, the joint 2 is still much more effective and durable. In my opinion, the solution of the square cutouts, it seems more effective than that based on the spheric joint, because it get the compression stresses in a way perfectly vertical. And It gives me the impression of a less precarious balance.
About the post of Minori. I could not understand how the left and right panels can be suspended (being only 45x45), and I'm not entirely sure there is a joint (made by 6mm plywood), capable of supporting such an effort. I suppose that with horizontal panels of various sizes (45x45 - 45x90 - 45x180) might be possible to make projections and lintels, but the horizontal joints would still be under great efforts.
It seems like the lateral force resistance is the issue in this joint system, as expected. As I have mentioned, finger joint is not really good in terms of taking lateral force, unless the direction is carefully mixed. I guess you guys need to check a bit larger scale (more extension of both in vertical and horizontal directions) to check the structural feasibility. Also, please note that the actual construction will be done by the CNC Router, not laser. Router cannot cut a sharp internal corner - there will always be a radius of cutting bit remained. To make finger joint really effective especially against the vertical stress, you need to make a special cut-in at the sides of finger joint corners. Please develop such cutting pattern as a basic detail, if you guys want to proceed this scheme.
I believe horizontal joint system appearing here needs fundamental reconsideration. The current cutting/interlocking method is quite doubtful to be effective, and also the nature of joint is too different from the vertical joint system. Please come up with more effective and conceptually coordinated idea.
