7. MakerBeam Standoffs or spacers
Electronics and manufacturer beams work well together. It is possible to slide the circuit board into the carriers. Unfortunately, this doesn't always work smoothly. The boards are filled to the edge with electronics, and the carriers are conductive. Mounting a circuit board on PCB spacings or spacers could be a simple solution.
Our package includes 4 spacers, 4 nuts, 4 screws (6 mm), and 4 washers. They are all in size M3 to complement MakerBeam well. This size (M3) means that this product is also well suited for OpenBeam. You can use the same hex nut wrench to secure the spacers. No other tools are needed.
