I call this “Dragon of the Sea” created with Hueforge. I used Sunlu Shiny Silk Grey and Bronze (Looks gold) but silver and gold can be used. I included layer heights if you want to experiment with other colors. I recommend changing the Orange if you do. Also included is a print profile for if you do not own an AMS, I added pauses to the appropriate layer heights for filament change. Let me know if you find any issues.

To use 5 filaments with 1 AMS:

Select the AMS slot containing black for the 5th color.
When Black layers are done printing, switch out the Black filament for 5th color.
