Eureka Mignon and a bottomless portafilter.

Grinders are one of the keys to exceptional espresso. Discuss them here.

Has anyone figured out a way to have the bottomless portafilter sit handsfree while grinding?

I use a funnel and have it set up to just barely balance. However, the funnel tilts a bit and some grinds spray out. Plus it's teetering on falling.

Maybe need to 3D-print a holder? I grind i to a dosing cup and pour into the portafilter after

I tried with a magnetic dosing funnel but it wasn't high enough to prevent a mess. Went back to using the dosing cup and realized the shaking I had been doing when transferring to the portafilter was a very effective de-clumping technique so I have since removed the de-clump fork inside the grinder which was a source of retention.

A 3D printer and neodymium magnets are your friend..!!

I found a Robot-specific DF64 mod to solve a similar problem on Thingiverse - there are probably already solutions out there for the Eureka Mignon too.

Thanks. I'll search for a 3D printed optioned. I tried the magnetic funnel and it still tilted.

I also plastidipped the fork hoping the stickiness would hold it better. That made it worst :(.

Magnetic dosing funnel works fine with the Specialita. But you have to adjust the fork height properly. And if you get an inclined stand, you need to ben the forks to bring the portafilter level again.

Yeah, I tried adjusting the height and angle of the forks. No luck. I think the plastidip made it stickier so it tilts more.
