Coffee powder hopper compatible with 51 mm, 53 mm, and 58 mm portafilters; lightweight design with a print time of approximately 1 hour per unit.

While some powder adhesion is inevitable due to material properties and FDM layer lines—though the amount is minimal—it has been effectively controlled thanks to adaptive layer height adjustments.

Modeled in Fusion 360; since creating purely circular designs felt a bit repetitive, I opted for this ice cream cone–shaped design 🍦—which also enhances grip comfort.

After verification, the dimensions should be compatible with most 51 mm, 53 mm, and 58 mm portafilters. However, if your specific portafilter still doesn’t fit perfectly after printing, we recommend fine‑tuning the dimensions slightly using scaling—this will ensure a seamless, custom fit.
