thingiverse
This is a grid aligner for the MAX7219 mega board, pcb that I have designed. 64 LEDS 10mm in diameter are arranged in an 8 x 8 matrix, giving a matrix dimension of 105mm square. Based on the standard 32mm sqaure led matrix modules available on the market, which are used to make scrolling LED displays. One image shows the red printed grid aligning the leds, one pic is shown without grid. Printed circuit board is available for purchase from your favourite auction site, just search for MAX7219 mega board and look for the red pcb. Also a video on your favourite video site.Search for the same. Instructions The red one shown in the picture was printed using red 3.0mm PLA 185 degrees C and sliced in Slic3r.
