A colleague asked me to make him this piece. Modelled in 2 sessions. First session is WIP file, which kinda works, but the grinder stone wobbles, as well as the hooks need to be thinner and a bit shorter. Adjusted those requests in the second version and here it is.

Colleague is happy with the 2-d file, so marking it as finished.

I recommend to use soldering iron at 220 deg celsius and quickly rub it over region with supports to melt together pieces of extrusion left. It will reduce chance of you swallowing a piece of plastic while drinking.
Or use paper filters. I don't really care :-D
