I needed a station that fits on Prusa Mini (just rotate it by 45°) for portafilter, funnel and tamper.
I have used it with this funnel https://www.printables.com/model/1220401-coffee-funnel-51mm and AliExpress tamper.
I was using it for years, until I sold the DeLonghi EC 685.M DEDICA coffee maker, it worked for me well.
