Rock Tumbler Ball Mill by TwitchyMcJoe Thingiverse
Jun 21, 2017 Just a simple rock-tumbler or ball mill that I needed to crush clay into powder.ball-mill Dealer, Fote. All it needs is balls inside of it and a belt/rubber band. I was thinking of adding a gear-drive mechanism later with a cam that would jostle the contents around. This is the simplest form.
