Viewers
Open any 3D printing file in your browser
Every viewer opens the file on your own device, shows it in 3D and gives you the real size in millimetres. Use them to check a download before printing, to look at a CAD file without CAD software, or to see what a slicer will do.

G-code viewer
Check a print before it starts: every layer, line and travel move in 3D, coloured by feature, with print time and filament. Reads plain .gcode, Prusa binary .bgcode and Bambu .gcode.3mf plates, so you can preview a downloaded print file without the slicer that made it.
3MF viewer
Opens Bambu Studio, PrusaSlicer and OrcaSlicer projects without installing them: every object with its name and filament colour, the plates of Bambu projects, the true size in mm and a measuring tool. Handy for MakerWorld and Printables downloads.
STEP file viewer
Look at CAD files without CAD software. Parts and assemblies exported from Fusion, SolidWorks, Onshape or FreeCAD open with their part tree, colours and real sizes, so you can check a design someone sent you.
STL viewer
The quick check for an STL: size in mm, volume, estimated filament weight, whether the mesh is watertight, and measuring between any two points. If it looks tiny, the file was probably drawn in inches.
OBJ viewer
OBJ files from Blender, 3D scans and asset stores, with their MTL colours. OBJ stores no unit and no fixed up direction, so the viewer lets you set both and shows the size in mm.
GLB and glTF viewer
GLB and glTF models from the web, AI 3D generators and Sketchfab, with their textures, materials and animation. Shows the real size and exports to STL or 3MF when you want to print one.
