Questions
How do I convert STL to 3MF?
Drop your STL file in the box. 3MF is already picked, so press Download.
Why use 3MF?
It's smaller than STL and stores units, so slicers like Bambu Studio and PrusaSlicer load it at the right size.
Is my model uploaded?
No. The file is converted in your browser.
