Split STL and 3MF files to fit your 3D printer
PartFit 3D is a free, browser-based STL and 3MF splitter for 3D printing. Orient oversized models, apply repeated planar cuts, and check every resulting part against a configurable printer build volume and safety margin. Each result gets a clear Fit or Too Large status, plus mesh and topology checks before export.
Model processing stays local in your browser, so no account, CAD installation, or model upload is required. Export slicer-ready STL or 3MF parts, then open them in Bambu Studio, Cura, PrusaSlicer, or another slicer to generate G-code.
