- A LEGO plate is one third of a brick: 3.2 mm tall on the 8 mm grid.
- 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.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
