The original Espresso dosing funnel by joochung is excellent, however I have the smaller 54mm portafilter used in my Breville Bambino espresso machine. I adjusted the sizing and the cutouts to accommodate my portafilter design
Printer:
Bambu Lab X1-Carbon
Rafts:
No
Supports:
No
Resolution:
.12mm
Infill:
15%
Filament:
eSun PLA+, Black
Notes:
Printed at 15% infill using black PLA + from eSun at .12mm layer height. Others are obviously fine as well. I went with a smaller layer height to get better resolution on the funnel angle, but I ran test prints at up to .28mm layer heights and it works fine if you don't care about the resolution as much and just want a faster print.
Updated using solidworks since I hate working with the SCAD files. I converted the original design from joochung into a solidworks file, then updated the dimensions and made 3 cutouts for the 54mm breville portafilter.
