Electronics and Makerbeam work well together as it is possible to slide the PCB into the beams. Unfortunately, the boards are filled to the edge with electronics and the beams are conductive so mounting a printed circuit board on PCB standoffs (or spacers) could be an easy solution. Our pack contains 4 spacers, 4 nuts, 4 bolts (6mm) and 4 washers. They are all M3 size to complement MakerBeam. You can use the same hex nut driver to fasten the spacers, you do not need another tool.
