Electronics and makerbeams work good together. It is possible to slide the PCB into the beams. Unfortunately this not always works well. The boards are filled to the edge with electronics and the beams are conductive. Mounting a printed circuit board on PCB standoffs (or spacers) could be an easy solution.
We are working to get these in our shop right now. Selling them as a small kit including the four standoffs, four bolts, four nuts, four washers.
Here are some pictures.
