The last time we ran into Ben Heck, the tinkerer extraordinaire was waxing poetic at Maker Faire about the Raspberry Pi and cheese curds. One more thing he also talked about, however, was his latest 3D printer project, which he now explains in greater detail in the latest episode of the Ben Heck Show. Improvements made to the device include use of a Birdstruder for easier access to the filament and the ability to print off an SD card if you don't have a computer handy. The 3D printer also sports an expanded 200-square-millimeter print area with a solid copper cover for added sturdiness and accuracy. As usual, size matters for Mr. Heckendorn so the device got a boost in portability, now neatly folding James Bond-like into a briefcase that measures 18 x 14 x 4.2 inches. Interested in a briefcase printer of your own? Well, Heckendorn mentioned during the Maker Faire interview that he's already working on an improved version and thinking about putting it up on Kickstarter so hope springs eternal. In the meantime, you can glean more details about the device by checking out the video after the break.
