Sources

https://www.imsfiltri.com/IMS-competition-Catalogue.pdf (archived) — Official IMS Filtri competition catalogue, read firsthand 2026-07-13. Its B70 (Ø 70 mm border, tamper 58 / 58.4 mm) list is headed 'E61 & compatible groups like ...' and names ECM among the brands — a basket maker classifying ECM as an E61 / 58mm brand and publishing the measured fitment. This is the measured basis for the diameter here.
https://www.ecm.de/en/products/mechanika-max-ii/ (archived) — Official ECM product page, read firsthand 2026-07-15. Confirms the Mechanika MAX II as a heat-exchanger machine with an 'additionally heated brew group', shipping a 'portafilter with double spout' and 'portafilter with single spout'. ECM's page does not print a portafilter diameter or the name 'E61', which is why this sits at the measured tier.
