Hey, that's neat! I use a scrap piece from a previous employer. It's a 2inch tall stainless steel combiner ring. Definitely not as cool as yours and definitely not light enough for magnetic holds. You win lol
Yeah but yours isn't made of plastic so I think we can both find things to be pleased about.
Thanks for the kind words!
Oh, for sure! It is annoying having to hold it as I work with it. But, I don't have a 3D printer, so I did what I could with the tools at my disposal. I am happy with it :)
If it's at all magnetic (I know some stainless isn't) then you could probably just slap a neodidlium magnet on either side to hold it. Or you could make something to locate the phlangey things on the portafilter and attach them to the outside of the ring? Could even be as simple as 4 nails with the tips ground off?
I have neodymium magnets from another project. I should do that. They're about 2cm in diameter, but I can probably cut them to size.
I am by no means sure of this, but wouldn't cutting them throw off the magnetic alignment?
No. The magnetism comes from macroscopic ordering of microscopic features.
Basically you know how if you strap magnets together you get big magnet? small magnet is smaller magnets strapped together.
Magnets are very fragile though and cutting them is hard.
I've broken several of them, and they kept their magnetism. Neodymium magnets are like friggin glass in their fragility, though.
