Notes

  • The LEGO system is built on an 8 mm square grid; a brick body is 9.6 mm tall, three plates of 3.2 mm.
  • Numbers come from a museum write-up that cites LEGO's own patent for the 4.8 mm stud.
  • 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.
