10-30 volt DC laptop power supply

Build like http://www.thingiverse.com/thing:1483629, but use https://smile.amazon.com/gp/product/B017SM1O98/ref=oh_aui_detailpage_o01_s00 for the board.

Make sure you print the correct version; most will want the 12v version which has a normal powerpole configuration (you can still put 5-32 volts in and it should work)
