High-detailed smoothable pen.
Done with Blender 2.63 and rendered with
Blender Cycles render.
Included two .blend files one with render setup and one without render setup.
The pen is one part and the mesh is build from quads
and few triangles. In files (.stl, .3ds) the mesh is build from triangles.
In .blend files cycles render materials included.
The color can be change easily.
All files were tested.
