    A border that runs through every layer, so the plates line up by their edges.

    4Size and thickness

    Detail

    Grid spacing for the outlines, not a minimum printable width. Finer detail uses more memory. The nozzle check below flags potentially fragile detail without changing your portrait.

    Choose the usable size for your printer; leave room for brims and excluded areas in the slicer.

    5Export

    Choose the files that match your printing method. Both downloads include the same layered portrait.

    Multicolor printer

    One multipart model with a filament slot for each nonempty shade.

    Manual changes or separate pieces

    A ZIP with a combined STL, separate layer STLs, 3MF, preview and instructions.

    Add a photo to enable the download.

    In Bambu Studio, match filament slots to your chosen colors and select a printer and process before slicing. The 3MF is not a ready-to-print profile.

    To resume a design, choose the same photo first, then load its settings. Settings files do not contain the photo.
