Sorry, don't understand the question and/or comment.
Occasionally I share patterns that I make from 3d modeling practice, doodling or experimentation. Also occasionally, I ask the community what type of pattern they would like for me to share. In this case, the only suggestion, so far, was for a grader.
The grey scale height map image can be thrown into different cnc software packages like Aspire or miscellaneous 3d software (free to expensive) and converted to an STL for cnc routing or laser engraving.
