ABOUT · STEP

The STEP file (.step / .stp) is a standard 3D CAD format that retains dimensional and topology data. Compatible with major CAD software including Fusion 360, SolidWorks, and FreeCAD.

  • Full-scale solid (mm units)
  • Editable dimensions and post-processing in CAD
  • Convertible with a slicer for 3D printing
