Help needed to create a high-quality STL file from 2D image

I’ve been trying for several weeks to create a 3D model based on this image, but I haven’t been able to achieve a satisfying result.
So far, I’ve generated a grayscale map using Depth Anything V2 in 16-bit, then converted it to 3D in Blender. However, I can’t manage to produce a model with good details.

Could someone help me with this and, most importantly, teach me how to do it properly?

Thank you in advance!

Hi, try using ReliefMaker. Download the trial and watch the tutorials. In less than half an hour you will have your excellent stl to send to your CAM.
