NOTE - this is very much a v0.1 - it works and I have used it and it works but needed to modify after printing (shave down the battery holder and make the 12v input a bit bigger, and the USB output a bit smaller and the mounts for the 12v to 5v need to be further apart) and haven't made those mods to the models.
