A 2x5x1 Gridfinity holder I've made to fit the portafilter of my Oster Prima Latte Touch on my cutlery drawer. Maybe it's compatible with other portafilters, share in the comments if so, I would be glad to know. I'm also uploading an A1 Mini profile with a dovetail cut of the model so it can fit in its table, just print and snap the parts together, that's how I've made it.
