I used the ColorMix shading app to add shading to the original spiral pot.

Learn more about Prusa ColorMix in the blog article.
To correctly open the 3MF project file (which includes virtual extruders), make sure to use PrusaSlicer 2.9.6 beta (or newer), which introduced support for color mixing. In older PrusaSlicer versions, the model would instead only use normal extruders.
Printed on PrusaXL using Prusament PLA Azure Blue and PineappleYellow, at 0.15mm layer height. You could print even at 0.1mm layer height to improve the ColorMix result (smoother shading).
The author remixed this model.
Added MMU color shading.
