I'm still experimenting with the best colors, and am trying to reach a combination of four colors so that you don't have to stay near the printer and change rolls in the AMS. This is a tentative combination that seems to work well. Feel free to experiment!

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

Filaments Used:
PLA+ Esun Brown
PLA+ Skin
PLA BambuLab Basic BambuLab Green
PLA White

Swap Instructions:
Start with Brown
At layer #7 (0.64mm) swap to Skin
At layer #9 (0.8mm) swap to BambuLab Green
At layer #11 (0.96mm) swap to Skin
At layer #12 (1.04mm) swap to White
At layer #21 (1.76mm) swap to BambuLab Green for the rest.
