3DR Solo DC Charger

I made a newer version of this - https://www.thingiverse.com/thing:2781475

The charger that comes with the Solo require AC power which makes it impractical on the road. This allows me to charge a pack with my car, but realistically isn't all that practical since it takes over an hour to charge a depleted pack. Nonetheless, it's been made and it does function.
