Hi Mike, A worm gear is going to be very challenging, but not impossible, because the feature is a repeating pattern. I would suggest using the same process as scanning a sphere in the volumetric accuracy vid in this post MetroY videos and comparison with SermoonS1 , and if you are still having issues, the second thing i would do is attach something that is not symmetric e.g. a bolt through the axle with some sort of rigid flag on either end, etc Get a bit creative with the approach but just make it unsemetrical so that there is enough of difference in the views. Good luck, and let me know how you get on
