Convert STEP to STL
Open the STEP, choose Export → STL and the file is ready for your slicer. The conversion runs on your computer, so the design never ends up on someone else's server.

Questions
Is the conversion free?
No: exporting is a Pro feature (Pro Online from €6.99 a month). Opening and viewing the STEP is free.
Will the STL have the right dimensions?
Yes. STEP files are almost always in millimetres and the STL keeps the same dimensions, at whatever scale you chose.
Can I convert just one part of the assembly?
Yes. Hide the other parts before exporting.
