54mm Portafilter Funnel Sit on Top

thingiverse

I wanted to create a customized funnel for my 54mm portafilter (specifically Breville style) that would make dosing and tamping a seamless process, minimizing mess in the process. I designed this funnel to sit perfectly on top of the portafilter's lip, allowing me to use a standard 54mm tamp just like normal. When printing, you can slightly downsize the file to achieve a light press fit that keeps the funnel securely in place. This is still a work in progress, and I plan to update the file as I discover new ways to improve its functionality.
