## What is 3D File Viewer?

PrintPeek is a fast, private viewer for STL, OBJ, 3MF, PLY, and ZIP 3D model files.

Open a model from Files, Mail, Safari, AirDrop, or the share sheet, then inspect it with a clean 3D preview. PrintPeek is designed for short maker workflows: preview the model, check the basic details, export a clean image or mesh format, and move on.

Main features:

- Preview STL, OBJ, 3MF, PLY, and supported models inside ZIP files
- Rotate, move, and scale models with simple gestures
- Switch between solid, edge, and transparent display modes
- Use front, top, side, and isometric view presets
- Check bounds, file size, face count, surface area, and volume
- Export PNG previews, OBJ, DAE, and DXF files
- Save PNG previews to Photos
- Works locally with no account, ads, or cloud upload

PrintPeek is intentionally focused. It is not a CAD editor, slicer, mesh repair tool, or printer control app. It is built for quickly checking and sharing 3D model files on iPhone and iPad.

The free version opens smaller files. PrintPeek Pro is a one-time unlock for larger files and export features.
