Four-Links – another Buckminster Fuller streamliner, Arrowhead teardropper, 3D printing and classic car restoration, Iowa trucking museum

* What car guys most know Buckminster Fuller for is the Dymaxion three-wheeled streamliner, but perhaps more car guys would be familiar with him if his plan to build a four-wheeled streamliner with engineering genius Harry Miller had come to fruition. AutoWeek’s Graham Kozak had more on those plans this week.

* Speaking of three-wheeled streamliners, the Los Angeles Times found this never-before-published photo of the Arrowhead teardrop car in its archives this week.

* Perhaps one day soon we can feed the plans to one of the above two cars into a big ol’ 3D printer and see a complete car come out the other end. Or so postulates Dan Carney in a Popular Mechanics article on 3D printing that’s been making the rounds this week.

* In eastern Iowa with time to kill? Richard Fleener of LegendaryCollectorCars.com recently was and decided to spend that time in the Iowa 80 Trucking Museum.

* Finally, it’s all about context.
