old tea pot Free 3D model

Old teapot from my summer cottage. I created 3d-model in my favorite Autodesk Inventor. And after unwrapping in 3dMax I put it into Substance Painter. Where I combined several standard materials ("Steel Rough", "Iron Old", "Steel Gun Mat", "Steel Rust Surface") with layers, masks and environment ("tomoco_studio"). I tried to use to build-in I-ray render in SP, but my pc is not strong enough for this, so i exported all textures to images and imported them to 3dMax mental ray. Such software labyrinth ;-), because of my strange skills.
