Watch the video for the description and the instructions about this thing. https://www.youtube.com/watch?v=sHNiz1mrfxI&feature=youtu.be Here are the cliff notes.. This is an all 3d printable LED candle that has an engineered switch that requires 2 paperclips and some copper tape. This example can be used as pumpkin lights - xmas ornaments - emergency lights or in this case somebody requested that I make a 3D printed hero clix barrier that looks like energy. Of course what better for energy than LIGHT.... This also has a 3mm acrylic adapter that you can use to make little LED signs I attached an example that look like an energy burst or flame. You would need a laser cutter for that piece however. The mechanics behind the switch is the interesting part- Use and abuse it all you want and see what else you can make from it.
