All-Aluminum Espresso

This was a super-quick project I did during a short obsession with coffee. I used the MITERS CNC mill to drill tons of tiny holes in the bottom of the aluminum espresso machine head on the right. My operating procedure was to pack coffee into the head, pour boiling water on top, then quickly bolt the pressure head on, and pressurize the system with the canister on the left. You can see my results in the tube!
