This is a 3D‑printed coffee portafilter and dosing ring set, specially designed for coffee enthusiasts—practical tools that enhance efficiency and ensure consistent espresso extraction.

Portafilter: Featuring a dual‑layer, stepped design, the base securely snaps onto the grinder’s dispensing spout or hand‑held portafilter, effectively preventing coffee grounds from spilling while also doubling as a fragrance cup.

Dosing Ring: A disc‑shaped tool with a handle, used to evenly distribute coffee grounds within the portafilter or dosing cup, preparing the grounds for the subsequent tamping step.

• Precise Powder Control: When paired with single‑dose grinding, this system allows for exact control over coffee powder weight, ensuring consistent results with every brew.
• Anti‑Spray Design: The portafilter’s sealed construction eliminates coffee dust scattering during grinding, keeping your work surface clean and tidy.
• Uniform Dosing: The dosing ring efficiently breaks up clumps in the dosing cup, creating an even coffee bed density and preventing channeling during extraction.
• Highly Customizable: As a 3D‑printed product, you can freely choose from a variety of colors and materials—such as food‑grade PLA or PETG—or even adjust the dimensions to perfectly match your specific equipment setup.
