About Open3D: STL & 3D Model Viewer
Whether you're a 3D-printing hobbyist checking an STL before slicing, a 3D artist previewing a GLB or FBX, or a CAD user opening a STEP or DXF, Open3D Viewer opens it instantly — without the paywalls and login screens other 3D viewers force on you.
SUPPORTED 3D FILE FORMATS
• Mesh: STL, GLB, GLTF, OBJ, PLY, 3MF, FBX, DAE, 3DS, USDZ
• CAD: STEP / STP, IGES / IGS, DXF
Export & convert
Turn OBJ, PLY, 3MF, FBX, DAE, 3DS and more into STL for 3D printing or
GLB for sharing. Files save straight to your Downloads folder — no
extra apps, no online converter, everything happens on-device.

About Open3D: STEP GLB STL 3D Viewer
STEP viewer. STL viewer. GLB viewer. OBJ viewer. FBX viewer. DXF viewer. 3MF viewer. USDZ viewer. All in one 3D model viewer app.
Looking for a STEP viewer for Android without installing Fusion 360? An STL viewer that just opens the file? A GLB viewer that doesn't ask you to register? Open3D Viewer opens STEP, STL, GLB, OBJ and ten other 3D file formats instantly. Tap a file in Gmail, Drive, Downloads or any file manager and pick Open3D — the model loads in seconds.
THE 3D FILE FORMATS OPEN3D VIEWER OPENS
CAD formats: STEP / STP, IGES / IGS, DXF
Mesh formats: STL, GLB, GLTF, OBJ, PLY, 3MF, FBX, DAE, 3DS, USDZ
Export & convert
Turn OBJ, PLY, 3MF, FBX, DAE, 3DS and more into STL for 3D printing or
GLB for sharing. Files save straight to your Downloads folder — no
extra apps, no online converter, everything happens on-device.
One app covers STEP viewer, STL viewer, GLB viewer, OBJ viewer, FBX viewer and DXF viewer on Android.
STEP VIEWER AND CAD VIEWER
CAD files like STEP, IGES and DXF used to need AutoCAD, Fusion 360 or SolidWorks. Open3D Viewer is a STEP viewer and DXF viewer for Android — open a .stp, .step, .igs or .dxf attachment on your phone in seconds. The geometry tessellates to a mesh so you can rotate, zoom and inspect on the go, without a CAD subscription.
WHO USES OPEN3D VIEWER
CAD engineers open STEP and DXF files from Fusion 360, SolidWorks, AutoCAD or FreeCAD on their phone without a paid seat. 3D printing hobbyists check STL and 3MF files before slicing in Bambu Studio, PrusaSlicer, OrcaSlicer or Cura. 3D artists preview GLB, OBJ, FBX and DAE files from Blender, Sketchfab or Maya without booting a laptop. AR enthusiasts drop USDZ and GLB models into their living room.
