The task of effectively creating this illusion in three dimensions, without resorting to hidden openings or gimmicky twists, seemed daunting until a Netherlands-based designer named Ulrich Schwanitz succeeded in printing the object recently. But Schwanitz, who posted a YouTube video of his design achievement in action, wouldn’t share his secret with the world. Instead, he made his “impossible triangle” available for purchase through Shapeways, a company that fabricates custom 3D designs, for $70.

Within weeks of Schwanitz’s “discovery,” however, a 3D modeler (and former Shapeways intern) named Artur Tchoukanov watched the video and figured out how to recreate the shape. He then uploaded instructions to Thingiverse, an open-source repository of 3D models and content. BoingBoing picked up the story (well, part of it), and “wrongly” credited Tchoukanov as the initial creator of the object.

The same day the story ran, Schwanitz sent Thingiverse a DMCA takedown notice and…
