Ryobi 18V Battery Powerstation Adapter

I have a ton of Ryobi 18V batteries that could be used to supply power during an outage or a camping trip. I've developed more high-end ones in the past ( https://www.thingiverse.com/thing:416... ). I found a small simple design on thingiverse (https://www.thingiverse.com/thing:410... ) and remixed it by adding a cover ( https://www.thingiverse.com/thing:456... ). This current design makes a cover that adds regulated 13.8VDC output to a cigarette socket.
