Photo to 3D bookmark: multicolor STL and 3MF

Turn an image into a colorful 3D bookmark. Adjust the crop, choose your filaments and download the design with its print plan.

What this tool does

  • Images reduced to 2–6 colors, depending on available content.
  • Crop, zoom and rotate before generating the bands.
  • Editable palette and customizable stacking order.
  • Closed STL or multipart 3MF, always with a color change plan.

How it works

  1. 01

    Choose and crop your image

    Load a JPG, PNG or WebP. The crop fills the bookmark without stretching the image. Move, rotate and zoom to frame the subject.

  2. 02

    Set colors and dimensions

    Choose the color count and assign your filament colors. Adjust width, height, corners, tassel hole and band thickness.

  3. 03

    Download and prepare the slice

    The ZIP contains your model and a file listing swap heights. Use 0.2 mm layers to follow the plan and verify the swaps in your slicer.
