Free 3D printing tools
Small, fast utilities for everyday 3D-printing jobs — convert file formats, inspect models, match colours. No signup, no upload; everything runs on your device. Built by the team behind Layerpaint.
3MF ⇄ STL Converter
Drag in a 3MF and download a clean STL — or an STL and get a 3MF. Preview it in 3D first. Converts in your browser, nothing uploaded.
Open converter →STL Viewer
Open and inspect STL, OBJ and 3MF models right in the browser — rotate, zoom, and read off triangle counts and dimensions.
Filament Colour Matcher
Paste a hex or pull colours from an image and find the closest real filaments across Bambu, Polymaker, Prusament and more.
Want to add colour to your model? Layerpaint paints per-region colours onto STL, OBJ and 3MF and exports a Standard 3MF your slicer prints in multiple filaments.
