Tile2

This is an example of how the 3 way joint would tile a hexagonal plate. The plate has stretch fabric in the middle. The bars are mostly 0.9 ft to 1.1 ft long. 3/4 inch EMT with 3/8 inch grade 7 bolts and washers. The trusswork on the ends could be further refined to facilitate plugs and sockets so that many plates can be fitted together. Hopefully a plate could be moved by one person and flat pack on a trailer. Cylinder is a 6 ft person for scale.
