Many old Gaggia machines used these plastic parts to reduce the wear caused by the Stainless Steel retaining ring and the brass portafilter.
It was a bad design decision, and since retaining rings are hard to come by, this is a great option to give your espresso machines many more years of use.
Print in ABS or ASA. This part will be in contact with heated metal!
I printed with 4 walls and a concentric top surface to have print lines that follow the path the curvature, but other settings should work.
This part fits several machines:
Gaggia Classic V2 2015 (RI9403, SIN035U)
Gaggia New Espresso Dose (RI8153)
Gaggia New Espresso Color / Pure (RI8154, RI9302)
Saeco Nina (SIN026XH)
Saeco Nina Cappuccino (SIN026X)
Saeco Sirena/Starbucks Sirena (SIN025RX)
