Mike Noto: Ring Model

^ This model is updated to 3D print. The gem has been removed so that I can attempt to inlay a real piece of soapstone into the physical model.

This was my first attempt at printing the ring. I would like to go back and scale up the ring slightly and reprint it in wax with a much higher level of detail compared to the ABS plastic.

I'm having an issue with this raised section (the part that is Turquoise in the render) I would like to offset the top surface inward so I could make the gem inlaid. I Tried offsetsrf, scale, scale3d, and a few other commands but nothing is working for me. I'm really unsure how to go about it since it curves on all 3 planes.

I also cannot fillet the wood portions (reference render) or even booleon union them to adjacent surfaces. I believe that if it is left as it is, the ring will not print.

I could not make the render 17 x 11, instead it is 17 x  9.56 at 150 DPI. It seems the proportions are
constrained and I cannot find a setting to change it.

I also think I'm doing something wrong with the Make2D command, there are a few lines missing.
