How to Open Your ButterySpace Bookmark ZIP
What's in the download, which file to open where, how to use it in mainstream slicers, and how to add your own colors. The files are geometry, and you choose the colors in your slicer.
When ButterySpace finishes generating your bookmark, you download a ZIP file. Here's exactly what's inside, which file to reach for, and how to get printing without confusion.
What's inside the ZIP
The ZIP contains exactly two files: the same bookmark geometry in two formats.
- bookmark.3mf: the model in 3MF project format, readable by Bambu Studio, OrcaSlicer, PrusaSlicer, and Cura.
- bookmark.stl: the same geometry as a single combined body, for the broadest slicer compatibility.
Both files describe a single combined object in shared millimetre coordinates, so there's nothing to align. Drop one file into your slicer and you're done. There is no SVG in the ZIP; the bundle is designed for 3D slicers.
Important: these files are geometry only. ButterySpace does not assign, bake in, or auto-load any colors. If you want a multi-color bookmark, you add the colors yourself in your slicer. It takes a minute, and our Bambu Studio color guide walks you through it.
Opening it in Bambu Studio
Open bookmark.3mf (or the STL, either works) in Bambu Studio. The bookmark loads as a single object. You choose your printer, filament, and layer settings as usual.
By default it prints in one color. To print the design in more than one color, use Bambu Studio's own color tools (the Color Painting brush, or a filament change by height) to paint the bookmark however you like. Nothing is set up in advance, so the colors are entirely your choice. The step-by-step color guide covers both methods.
Opening it in OrcaSlicer, PrusaSlicer, Cura, or another slicer
Open bookmark.stl. It's a single combined body, so there's no import-as-assembly step and nothing to align. Just import the file. The 3MF opens in these slicers too, but the STL is the simplest path.
As in Bambu Studio, the model arrives as plain geometry. For a multi-color print, use your slicer's own color or multi-material tools (color painting, or a per-height color change) to assign colors yourself. For a single-color print, just slice and go.
A note on color
It's worth repeating because it's the most common question: the bookmark is not pre-colored. The download gives you a clean, two-sided bookmark shape. Whether you print it in one color, two colors, or a rainbow is decided entirely in your slicer, with your filaments. We hand you the geometry; you bring the color.
A note on print settings
The bookmark download gives you the model files. You choose your printer, filament type, layer height, and other slicer settings. Those aren't baked in. The bookmark should look good across a range of common configurations, but your specific setup will determine the final print quality.
