## Overall (mm)

| length | width | height |
|---|---|---|
| 50.0 | 50.0 | 70.0 |

**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## Notes

- Exact nominal dimensions. Base 50 × 50 mm, 43.5 mm tall (41.0 body + 2.5 step); datum is the base centre, bottom face on z=0; interface and USB connectors on the −X face.
- Scanner head Ø42 (largest of the Ø42 / Ø40 / Ø37.5 head diameters), from the base top to 70.0 mm overall height.
- Measuring window: the band from 46.0 to 64.0 mm above the base bottom (18 mm tall); keep it clear all round for the scan.
- Two M3 threaded holes in the bottom face, 6 mm deep, at diagonal corners of a 40 × 40 mm square centred on the base: (+20, −20) and (−20, +20).
- Modelled: base, head, M3 holes. Not modelled: connector openings, base corner rounds, window recess and cable notch.
