BLM LED Substrate

Here is an LED BLM substrate- you can put it in your window or if you have a battery pack you can attach it to your backpack for some peaceful protesting. It is made for an LED string that I already had, the one shown in the photograph. The LED diameter is 8mm and the shaft diameter is 14mm. I printed each letter separately and glued them to the connecting brackets with thick beads of hot glue.
