Those of us who are into 3d printing probably know about Bergman and TigerAce1945's 1/100 scale tanks on Thingyverse.

If you don't then they're a huge collection (literally 100's) of FREE 3d printable military vehicles.

TigerAce1945 has posted on FB that he and Bergman have had most of their models taken off Thingyverse as Wargaming World Limited (the makers of World of Tanks) DMCA’d their models.

WWL recently started selling WoT tanks on Shapeways so I wonder if they're going claim copyright on all 3d printed tanks.
