About this 3D model

I have recently taken up a new hobby, clay modelling, more to the point modelling with cold porcelain, and as an owner of a 3D printer, I can make tools that will help make all different types of shapes etc. This is one of the tools, it's a kind of flattener, but it's a bit more, you can cut out an oval shape, or sections of, on one side is a smooth(ish) serface to flatten the clay, on the opposite side I have put some grooves, to put cool looking lines into the clay. I hope someone gets some use from it. Thanks for looking :-)
