Portafilter Funnel 58mm

I wanted a portafilter funnel to keep more of my ground coffee in the portafilter and less on the kitchen bench. Especially when WDTing. I couldn't find any on Thingiverse that was exactly want I wanted, so I designed one.

This one has been designed so the grinds can also be tamped through the funnel. The small inner lip is there to prevent grinds sitting on the rim of the basket.

Print it upside down so no support is needed.
