If you are experimenting with the standard MAX7219 matrix modules, (pcb 32mm x 50mm approx), this is a simple joiner bar to daisy chain them together. You will need M3 x 8mm long screws and preferably M3 nyloc nuts so they don't come undone. The bar narrows to allow the soldered connections from the MAX7219 chip to be fully seated. Instructions 3D printed in PLA. 0.3mm Layer height.
