About STL Splitter

Free online STL splitter. Cut large STL or 3MF models into pieces that fit your printer bed, add interlocking pegs, and export—no upload, no signup. STL Splitter is a free browser tool for 3D printing. Load an STL or 3MF, pick your printer from 70+ presets, and it cuts the model into bed-sized parts with optional interlocking pegs. Everything runs locally in your browser, so files are never uploaded. No account, no watermark.
