This is a simple 3D-printed dosing ring designed to fit onto the Zerno dosing cup and streamline the espresso workflow.
Instead of using the dosing cup and a separate dosing funnel, this ring lets you use both functions together:
Attach the printed ring to the Zerno dosing cup.
Place the dosing cup directly onto the portafilter basket.
Transfer the coffee into the basket.
Lift off the dosing cup — the printed ring stays on the portafilter and acts as a dosing funnel.
Perform WDT without needing to swap accessories.
The goal is simple: fewer accessories, fewer steps, and a faster WDT workflow.
Designed specifically around the Zerno dosing cup and standard espresso portafilter baskets.
