3D Model Viewer

3D Model Viewer is a compact utility for inspecting 3D models on your Android device, letting you open files you have downloaded or load models directly from your browser or file manager. The app focuses on fast, reliable previews: tap and drag to rotate a model, pinch to zoom, and switch to a VR view when you want an immersive look. Because it can become the default handler for STL, OBJ and PLY files, it streamlines the workflow for designers, students, and 3D-printing hobbyists who need to check geometry on the go without a desktop application.

Key Features

⭐ 3D Model Viewer opens downloaded models or files directly from your browser and file manager for instant previewing.

⭐ Native support for common 3D formats: STL, OBJ and PLY.

⭐ Intuitive touch controls—tap and drag to rotate models, pinch to zoom for detail inspection.

⭐ Built-in VR mode lets you view models in compatible headsets such as Cardboard and Daydream.

⭐ Option to set the app as the default handler for supported file types so models open automatically.

Advantages

✅ 3D Model Viewer offers a simple, uncluttered interface that makes previewing models quick and straightforward.

✅ VR support provides an easy way to examine scale and depth in an immersive view.

✅ Supports the widely used STL, OBJ and PLY formats, covering most common model files.

✅ Integration with browsers and file managers speeds up workflows by opening models directly from other apps.

Disadvantages

❎ Limited to viewing only—there are no built-in editing, measurement, or annotation tools.

❎ Supports only three file formats, so less common model types are not handled.

❎ VR functionality depends on compatibility with specific headsets such as Cardboard and Daydream.
