Notes
- Datum: shaft axis on Z at x=0, y=0; back terminals on z=0, output face up.
- Motor can Ø12.0 with flats to 10.0 (z=2.8..16.8); gearbox 12.0 × 10.0 × 9.0 (z=16.8..25.8).
- Output shaft Ø3.0 D-shaft, 10.0 long, flat 0.5 deep.
- Two M1.6 tapped holes in the gearbox face at (+3.8, +2.8) and (−3.8, −2.8), 9.44 apart diagonally.
- Same outside for HP, MP and LP 6V and every ratio except 1000:1 (12.0 mm gearbox); carbon-brush (HPCB) and extended-shaft versions are longer and not modelled.
- Exact nominal mm; terminals modelled as tabs, the small rear boss is not modelled.
