What is MakerTools3D?

MakerTools3D is a free set of web tools that turn images into printable files, with a clear focus on multicolor printing. The main one, Image to 3MF, takes a PNG or JPG, reduces it to between 2 and 16 colors and exports a 3MF where each color is a separate part you can assign to a filament in OrcaSlicer or Bambu Studio. You can click the source image to pin exact filament colors, set the final width, thickness and mm per pixel, and choose a flat multicolor plate or a relief where each color gets its own height. Fully transparent PNG pixels are left out of the mesh, so the background disappears and inner gaps become real holes, which is handy for keychains and badges.

The other tools cover image to heightmap and image to lithophane (both STL or 3MF), a PNG to SVG tracer for slicer modifiers, and a converter from textured GLB models to Snapmaker Orca FullSpectrum 3MF. The most unusual one is Apply Image to Model: you load an STL or 3MF you already have, place an image on a chosen face, then move, scale and rotate it before downloading a colored 3MF.

It suits owners of AMS-style and multi-toolhead printers who want logos and signs without painting in the slicer. The domain was registered in May 2026, so the site has little track record.

What you can make

• Multicolor logo plates and signs
• Keychains, tags and badges with cutout outlines
• Color images applied to an existing STL or 3MF
• Heightmap relief plates
• Flat lithophanes
• FullSpectrum 3MF files from textured GLB models
