OK, I ran a couple using MeshCAM. Used the original huge file. Scaled in MeshCAM to 3"x3". I had to scale the Z down to fit my board thickness, so I lost some detail.
The wood is called either Goiabao or Guatambu. It's left over flooring from my house. They called it Brazilian maple, but it comes up under both names on different web sites. I tend to think Goiabao is correct, though.
