Those that follow either Thingiverse or 3D art will likely be familiar with Dizingof. Asher Nahmius is a Thingiverse Superstar famous for beautifully confusing 3D math art, but in an odd case of copyright infringement he removed all of his files from the site. Nahmius felt his intellectual property was used in a manner by Stratasys and 3D Systems that violated its Creative Commons – Attribution – Noncommercial License. Models that Nahmius uploaded to Thingiverse under that license were printed on a Stratasys printer and displayed at a Stratasys booth without attribution, and a similar incident occurred involving 3D Systems.
