About this 3D model
I used paused at layer height to do the color change, but with an AMS I'm sure it can be done cleaner! 0.18-0.28 should work great! This is eSun PLA+, but I think PETG or ABS would be better. I am currently using Orcaslicer so I cannot post print profiles at this time, but I may try to in the future.
