Open 3D Model Viewer – Free, Open-Source productivity tool for 3D designers, 3D printing enthusiasts and game programmers.

Download (v1.1, Windows 32 & 64 Bit)

Installer-less version (ZIP, Windows 32 or 64 Bit)

Massive 3D Format support

Powerful 3D Viewer and basic editor for 40+ file formats, including OBJ, 3DS, BLEND, STL (more info), FBX, DXF, LWO, LWS, MD5, MD3, MD2, NDO, X, IFC and Collada. One of only a few independent FBX Viewers.

Rapid User Interface

The Model Viewer has a tabbed UX so multiple scenes can be open at the same time. 3D views are split in up to four viewports. Different camera modes (orbit, FPS or axis-aligned) are available for each viewport. New files are loaded in the background.

Coming soon: Mesh repair for 3D printing

Soon there will be 3D-printing specific tools to fix any issues that could impact 3D printing quality.

Edit & Fix

Common glitches such as inproper normal vectors, flipped UV coordinates (or textures) or degenerate geometry can be fixed directly in open3mod.


Export scenes, parts of scenes and textures to a multitude of destination formats, including OBJ, PLY, 3DS, Collada and STL.

Skeletal Animation

Plays even complex skeletal animations. Individual frames can be locked, playback speed is adjustible and scene transformations can be inspected anytime.

Hierarchy Inspector

Deep looks into the scene hierarchy, targeting 3D developers who need to integrate 3D scenes into their engines.
