I designed this portafilter funnel, because I didn’t find any that looked nice, cleared my mill and had magnets instead of using the lugs of the portafilter. So I made this nice funnel.
You’ll need 6mm diameter magnets with 3mm thickness for this design. Thicker magnets could be easily remixed into this design. Thinner would be too weak for me. Stop the print in the planes with the overhangs for the magnets , insert them and resume the print.
UPDATE: I added a model with 2mm thickness, if it's easier to source for you. Haven't tested the magnetism on that particular variant yet. Please slice it for your own needs. The insert pauses aren't defined yet.
It’s tested with the ECM Portafilter, but it should work with any 58mm/E61 portafilter out there.
The author marked this model as their own original creation.
