If you need to modify the STL model, you can do so using its several designing tools. Furthermore, it lets you convert STL to other 3D files like GLB, FBX, 3MF.

STL files are everywhere. When there’s something to 3D print, it’s probably going to be an STL. Which, as long as the model is good just as it is, is no trouble at all. But sooner or la… ...

With this change, one can now drag .stp or .step files directly into PrusaSlicer for printing. First, a brief recap. In the world of 3D models there are two basic kinds: meshes and CAD models.
