How to use

1. 1 Photograph your plate — lay it flat, shoot from directly above in good light so all four corners are visible.
2. 2 Select your plate size and upload the photo. The app will auto-detect the plate boundary.
3. 3 Adjust the corners — drag the green handles until they sit exactly on the plate edges, then confirm.
4. 4 Mark the dirty spots — use the brush or polygon tool to mark any plastic residue. A 2mm margin is added automatically.
5. 5 Generate & download the 3MF — open the file in your slicer. Each marked area appears as a separate object. Remove the reference frame before printing.
6. 6 Print directly on the dirty plate — the cleanser objects stick to the residue as they print.
7. 7 Let it cool and remove cleanser objects — the residue is removed with the cleanser objects. Repeat if necessary
