@xabean Nice! Nerds of a feather! :D
@jws at some point I might figure out how to embed magnets? Haven't done it yet, because the single print I made of it has worked out Well Enough[tm] 🤣

@xabean I was thinking something like that, and didn't for the same reason.

I downloaded a model from printables for the 49mm portafilter my Zacconi uses, but it didn't have enough of a "lip" and would slide off when I was stirring with a distribution tool, so I re-did it with some gaps for the "ears" like you did.

@jws love it. Small interactions like this was why I shared, thank you for sharing your design!
