That's pretty good detail for no dots. The scanner I borrowed was the creality ferret. It was "OK" but I didn't have a lot of time to learn the nuances and had to give it back. I'd like to try one that has blue light scanning at some point.
I actually made and used a probe for one of my CNC machines years ago and wrote a macro to record the points in space to make the point cloud, then turned it into mesh in blender to export STL files for printing. Pain in the *** but it worked. Fun times lol.
