https://home.lamarzoccousa.com/product/basket-advanced-precision/(archived) — Official La Marzocco Home (USA) product page, read firsthand 2026-07-04. Describes the stainless steel filter basket ('Advanced precision for consistent extraction. Superior material & finish with zero defects.') available in 7g, 14g, 17g and 21g sizes, and states verbatim that it 'Fits all La Marzocco portafilters.' The page does not print a numeric diameter or depth; the 58mm figure follows from La Marzocco's own statement on the Linea Micra page that its Home-line portafilters take 'standard 58mm tampers'.
