About
Converts .3mf files to Snapmaker U1 format, right in your browser. Two ways to use it: AUTOMATIC: Download a .3mf from any site (MakerWorld, Printables, Thingiverse, etc.) and the extension intercepts it, lets you adjust the filament mapping, and saves the converted file. MANUAL: Click the extension icon and drop in a .3mf you already have on disk. Works with files from any slicer: • Bambu Lab / OrcaSlicer • PrusaSlicer / SuperSlicer • Standard 3MF format • Generic files (falls back to single PLA filament) Features: • Filament mapping UI with color picker (56 presets + hex input) • Drag-and-drop slot reordering • Automatic Tree Support detection • Recognizes files already configured for U1 and skips unnecessary conversion • Preserves original filename (saves as "Model Name-U1.3mf") • Option to download the original unconverted file • Handles any number of filaments, maps them to the U1's 4 slots Everything runs locally in your browser. No data is sent anywhere, no account required, no server involved. The converted file opens in Snapmaker Orca for final slicing. Open source: https://github.com/ericreid/3mf-to-u1
