## Overall (mm)

| length | width | height |
|---|---|---|
| 90.0 | 25.05 | 25.0 |

**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. Body 90.00 × 25.05 × 25.00 mm (length × depth × height) with full-round ends; datum is the body centre, bottom on z=0, lenses facing +Y.
- Back face: two M3 threaded holes 45.0 mm apart, at x = ±22.5, mid-height; maximum screw insertion 3 mm.
- Bottom: one 1/4-20 UNC tripod hole on the body centreline in X; its front-to-back position is not dimensioned for the D435 (modelled at the centre) and the 9 mm depth is taken from the D436 drawing. Verify before relying on it.
- Front (not modelled, all on the lens centreline, from the 1/4-20 centreline): left imager / depth origin −17.5, RGB −32.5, IR projector +11.5, right imager +32.5 (50 mm baseline). Depth start 4.2 mm behind the front glass.
- Not modelled: end radii and the USB-C port. D435i uses the same drawing; D435f/D435if are about 25.8 mm deep.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)

| feature | exact | mates with | fit | files |
|---|---|---|---|---|
| rear mounting holes | 2 × M3, 45.0 apart, mid-height, 3 max insertion | M3 screws ≤ 3 mm into the body | designed | all |
| tripod thread | 1/4-20 UNC, bottom face, on the X centreline | 1/4-20 camera screw or tripod | designed | all |

## Sizes

| feature | x mm | position | size |
|---|---|---|---|
| M3 hole 1 (back) | -22.5 | z 12.5 | M3, 3 max |
| M3 hole 2 (back) | 22.5 | z 12.5 | M3, 3 max |
| tripod (bottom) | 0 | centreline | 1/4-20 UNC |
| left imager (depth origin) | -17.5 | front | — |
| right imager | 32.5 | front | — |

## Questions

**How big is the RealSense D435?**

90 × 25 × 25 mm (90.00 × 25.05 × 25.00 mm per the drawing).

**How do you mount a D435?**

Two M3 holes in the back, 45 mm apart, max 3 mm screw insertion; or the 1/4-20 tripod hole underneath.

**Where is the depth origin?**

At the left imager, 17.5 mm from the 1/4-20 centreline; the stereo baseline is 50 mm.
