I made this to clear my counter and still let me have a month of espresso single dosed out. I roast my own coffee and use different rows for the different kinds of coffee. It has a print in place bearing so that it can spin around. An o-ring provides tension to keep tubes from falling out. The tubes can be pulled out, used, and reinserted at the top to FIFO (First In First Out) the tubes. I use different color test tuvbe lids for arabica and robusta beans.
The model prints in 2 parts so that no supports are needed.
