Espresso 58mm Dosing Ring Funnel

thingiverse

We need coffee to sharpen our senses, but we need that same precision in order to make the coffee? That's a catch 22 is there ever was one. Here's a dosing ring funnel tool to move the espresso grounds all into the right place. Designed for a standard commercial size portafilter (fits 58mm). It's overall dimmensions are 75.3mm x 29mm. Has contoured walls for better grip and less slip. Sorry I only have a 58mm size, 'cause that's the only portafilter size I got for designing with.
