Print 2 of the grid parts from opaque material. Print 2 end panels and 1 center panel from translucent material. The two grid parts are connected with the center panel, then the end panels go on either end. This assembly sits down on the 8x32 LED matrix. On the back of the matrix board I used double sticky foam tape to attach a lexan panel cut to match the matrix frame (83mm x 323mm). Leave channels between the pieces of tape for the LED power wires. I used clear packing tape to attach the layers together, then used the foam tape to attach rare earth magnets to the rear corners to mount the panel in my computer case.
