    Hello, I need to get some LED lights to go into some of my 3D prints. I want them to be able to be run from a USB port. I have looked into turning 5v into 2.4v with a voltage divider, but I would really like to find some little circuit boards that will fit inside some of my smaller prints. I can't seem to find anything like this anywhere, any suggestions?

    2.4V will work ok for some leds but it will burn up or shorten the life of others
