3D-printed gun folds and shoots paper planes

Why would you fold and throw your paper planes by hand when you could get this beautiful machine to do it for you?

Some people are passionate about coffee. Others about books, movies or games. There are, to paraphrase a certain timeless tale, as many passions as there are people. Dieter Michael Krone's passion is paper aeroplanes.

The Düsseldorf-based mechanical engineer is one of the world's leading authorities on the art of folding paper to make it glide. He has written a book on the subject. He has given a university lecture. He has an extensive website which lists the best materials for building paper aeroplanes; a history of paper aeroplanes; an essay on the physics of paper aeroplane flight; and, of course, a number of instruction sets for paper aeroplanes of his own design.

And, it turns out, he's also something of a mad genius, as detailed on his YouTube channel. There, you can find a paper aeroplane made out of a burger box, an exploration about whether a paper aeroplane can carry an egg, paper aeroplanes that can embed themselves into a dartboard, and this magnificent creation.

Dubbed the A6 v1.0, it's a 3D-printed thing of beauty. Like a printer, it holds a stock of paper which, one by one, it folds into a paper plane, then shoots into the air.

"A little tinkering from me that shows what you can do with 3D printers today. Most parts of this paper airplane machine gun had printed by fabberhouse.de (the rest of them are to buy via Internet or hardware store)," Krone wrote in the video description. "By the way, I use a cordless screwdriver from China for driving."

He hasn't listed specifications for printing your own anywhere on his website that we could see, or indeed any further information about its construction, but one thing's for sure: if he were to put this thing on Kickstarter, we'd be there in a heartbeat.
