I’m not a modeler or texturer.  I’ve dabbled in it enough to understand workflows, but not practiced enough to make awesome-looking things.  Evidently, with the advent of 3D modeling and 3D printing, a number of sites have popped up where people put up free 3D assets.  For future reference, here is a list of the ones I’ve come across:

  • Archive3D – looks like it is run by Adobe and their Creative Cloud service.
  • CG Trader – marketplace and a place for free downloads.
  • TF3DM
  • Thingiverse – Especially for use with MakerBot 3D printing.
  • TurboSquid – nice filter system by file format, software program, etc.
