Free browser tool that splits oversized STL/3MF models into bed-sized parts with interlocking joints. No upload, files stay on your device.

I kept running into oversized STL and 3MF models that would not fit my printer bed. Other splitters wanted a file upload or a desktop install, and I did not want to send models off my machine. I built a free in-browser tool that splits files locally into bed-sized parts with interlocking joints, so the files never leave the device.
