STL Generator

Advanced tool to convert images into print-ready 3D models. From a PNG or SVG file, it generates a solid STL with independent height control for the image, base, border and text. Automatically adds a base and border around the image, custom text with its own height, and supports filament colour changes during printing via Z-height pauses in your slicer (such as PrusaSlicer). Designed for FDM printing and users who want clean, predictable results without CAD software.

How to use it

1. Upload a PNG, JPG, or SVG image.
2. Adjust the threshold until you see the mask you want.
3. Configure dimensions and optional layers (base, border, text).
4. Click "Generate STL" and download the file.
5. Import into Cura, PrusaSlicer, or Bambu Studio and set filament change events at each Z height.
