I created this set of Hueforge bookmarks so that all four bookmarks can be created with the same layer settings at once. This print uses six colors, but due to Hueforge's layered printing, you can still print using a single AMS or without AMS.
If you don't have an AMS, you just need to replace the filament manually every time it needs replacing. If you only have one AMS, the process is a bit more difficult.
Cut the model normally, but add a pause at the 11th layer (0.96mm) before the color turns orange, to swap one of the two completed colors (light blue, dark blue, or black) and swap orange and white. Before starting the print, you need to decide which slot to replace with which color, so don't forget the slots you've chosen for orange and white.
