- Logitech MX Ergo wireless trackball measures 132.5 × 99.8 × 51.4 mm (5.22 × 3.93 × 2.02 in) according to Logitech; trackball, length × width × height; Logitech prints this as 132.5 mm H × 99.8 mm W × 51.4 mm D, where its 'height' is the front-to-back length and its 'depth' is the thickness.
- The size of the removable tilt plate is not published separately.
- 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.
