3D Models Previewer

3D Previewer — see every 3D model you own, instantly.

Point it at any folder and it finds every STL, 3MF, OBJ, FBX, GLB and glTF file inside, grouped by folder with real 3D thumbnails. Click one to spin it in full 3D, with its true size in millimetres, triangle count, estimated weight and filament cost, and whether it fits your printer's bed.

Tidy a messy download folder in minutes: find duplicate files, move, rename and delete (with Undo and a Trash), tag favourites and add notes. Check models before you print with a mesh-health check, a cross-section view and a measuring tool. Preview lithophanes lit from behind. Combine several parts onto one 3MF plate and open it straight in your slicer. It also reads Bambu, Orca and Prusa 3MF projects (plates, filament colours, print times), makes turntable videos and printable catalogues.
