Overall (mm): length 124.9, width 84.3, height 51
- Logitech MX Master 3 wireless mouse (2019) measures 124.9 × 84.3 × 51 mm (4.92 × 3.32 × 2.01 in) according to Logitech; mouse, length × width × height; Logitech prints this as 124.9 mm H × 84.3 mm W × 51 mm D, where its 'height' is the front-to-back length and its 'depth' is the thickness.
- MX Master 3, 3 for Business and 3S share the same published shell size, so mouse docks and holders carry over.
- No CAD file: the maker publishes only overall sizes, and a plain box or cylinder is not useful design geometry. The table is the published data; parts with real geometry have their own pages.
