Simple Dummy Man 3d model, not rigged. Only OBJ file published for the 3d model. I don't think any one could require any other 3d applications file types than OBJ. Because OBJ files are universal file type and can be opened with any 3d software. By the current situation the 3d model could be used as base mesh for sculpting. If you wish you can use it for stock image scenes after simple rigged it.
