business card holder
Customize business card holder, you can add two leds to make the flash light, also cover the back of the leds so the light won't light from the back. I use some hot glue and acrylic paint to cover the back side, feel free to improve it. You can cover wire to your liking. I add at the end a print of my channel, you can customize the plate.
