PartFit 3D is a private, browser-based STL and 3MF splitter for 3D printing. Orient oversized models, make repeated plane cuts, check every result against a configurable printer build volume and safety margin, inspect mesh issues, and export slicer-ready STL or 3MF parts. Model processing stays on your device, with no upload or account required.
