Design made entirely in Fusion 360.
Bottom cylinder has 51mm in diameter, fits perfectly a 52mm coffee filter/sieve. This design was made to be used with Zelmer ZCM2052B / ZCM2052R (Piano 13Z014) coffee machine - and it works. For final use i had to sand a little bit of bottom edge - but i think it's due to poor setting of Z-offset in my 3d printer :). Rest worked just fine.
