DasTri creates 3d-Models:
The modells are currently stl-files. On request in colour as obj-files too. You can get the files on servers from DriveThruRPG or Cgtrader for download or Shapeways as printed product.
Some models are available for free to test the quality of the products. You do not have to buy a pig in a poke.
All shown pictures of prints are printed on a Dremel Ideabuilder 3D20 with standard configuration and PLA-filament.
