Almost a chuckle

Wow, that brings back memories. Slackware 3.x was my into to Linux in the '90s.

I know it’s probably sacrilege, but I avoid the need for one of these by grinding half a dose, tamping a bit then grinding the rest and finishing the tamp. I’m using a Breville Barista Express so couldn’t (easily) use one of these even if I wanted to.

I’m curious how you retain the magnets in it? Are they printed in, or mechanically added later? (I know very little about 3d printing, this just came up in my top-6-hour feed)
