Just bought my first batch of beams, great stuff. What I would like to see as new products is
- rubber or plastic plugs, maybe squarish to joint two beams slot to slot. The ridges in the slot would probably provide enough friction for is to stay put. This would allow you to join small 8x8 beams in corners easily, as well as joining a 8x8 with a 8x24 to create a t shape.
- some stuff to be able to fit a pcb snugly into the threaded slot. It occurred to me that you could create a perfect slide-in box for a pcb this way.
