	#Method 2 - Solderless version uses conductive paint. 3D print conduits for conductive paint, put components into small holes on other side, bending leads for good contact. Resistivity of the commercial conductive paint is 1 ohm per inch - workable for logic circuits but not power circuits above 1A. Instructable - [https://www.instructables.com/id/3D-Printing-3D-Print-A-Solderless-Circuit-Board/]. Compare to resistance of copper, perhaps 1000x less?
