Gents and gals,
I have been making and selling cnc patterns for several years now. I have also shared patterns that were either tests or for fun. I only ask that the patterns themselves are not sold but you are welcome to make and sell any physical items carved from them.
Most cnc software can convert grey scale depth map images to STL or other 3d format files. If not, there are several online sites that can do the same.
Hopefully of use to someone.
