Free online STL splitter

2 followers

Multipart3D is a free online STL splitter. Open an STL or a painted 3MF, cut it into parts that fit your 3D printer, add connectors so the pieces go back together, and export the parts for your slicer. There is nothing to install, no account, and no upload: the model stays in your browser tab from start to finish.
