How does a stacked multi-color bookmark save filament on an AMS?

Each color is its own height band, so no layer ever contains two filaments. The printer only purges when it moves up to the next band — a few swaps for the whole print instead of one per color per layer.

Can I print it on a single-extruder printer?

Yes. Download the single STL and add a filament change at each swap height listed in the tool. The print pauses, you swap spools, and the next band prints in the new color.

Can I snap the photo to the filament colors I already own?

Yes. Snap to my colors maps every pixel to the nearest slot color you picked, so the print matches your AMS loadout. That matching mode is included with Plus and Pro.

Photo

Bold posters, logos, and book covers work best. Busy photos flatten into blobs — that is the look, so crop tight on the subject.

Base

The photo is split into 4 regions; each slot just chooses the filament for its region, so any custom color works. The small swatch restores the color the photo actually had.

Bands are multiples of 0.2 mm layers. 0.4 mm hides the color underneath with most PLA; go thicker for light colors over dark, or thinner for a flatter feel.

Why stacked bands, not side-by-side colors

One filament per layer. Slot 1 prints the whole base. Slot 2 prints a band on top of it everywhere slot 2, 3, or 4 should show. Slot 3 covers slot 3 and 4 areas, and so on. No layer mixes filaments, so an AMS purges only 3 times for the entire bookmark instead of on every layer.
Single extruder works too. Download the STL, then add a filament change in your slicer at each start height listed above (0.2 mm layers). The printer pauses, you swap the spool, and the next band prints in the new color.
Slot order is stack order. Higher slots become raised relief, lower slots sit in the valleys. Use the arrows to move a color up or down; the most common color makes the cheapest base.
Opaque filament. Bands of 0.4 mm (two layers) cover the color below with normal PLA. Light or translucent filament over dark may need 0.6 mm. Matte prints read cleanest.
The Bambu / Orca 3MF loads as one object with one part per slot, each already assigned to its AMS slot. Every export also includes a print-plan.txt with the swap heights. Downloads use one of your 3 free exports per design; re-downloading the same design in another format is free.
