# 3D preview and printer-ready 3MF

After you open a file, the report shows the model in 3D.

- **Drag** to turn it, **scroll or pinch** to zoom, and use **Top**, **Front** and **Side** for flat views with the sizes marked.
- **Pick your printer** under the preview. A green line means the model fits its bed and height; red says which size is too big. Turning it 90° on the bed counts.
- **3MF for your printer** puts the model in the middle of the bed with the quality you pick (Standard, Fine, Draft or Strong) and no brim, ready for your slicer. See [Printers and 3MF downloads](/docs/guides/printers-and-3mf).
- **STL** and **GLB** downloads are beside it, and the camera button saves a screenshot.

The 3D view is only available for a file you've opened in this session; a saved report keeps its numbers, not the model (unless you kept the original file).
