Drill'nChill

When you're hankering for a cold drink but all you've got is warm, enter the Drill'nChill. Snap this puppy onto the rim of an aluminum beverage can, chuck it into your drill and spin it in ice water for a minute or two. Works good! The hardware is a 1/4" flathead machine screw with associated washer and nut. And, so you don't damage your manicure in removing this thing from the can, I include a tool to PopOff the Drill'nChill! It uses a U.S. 5 cent coin as a tooth (21.1mm in diameter and 2mm thick). #ELEGOO3DPSummer

Added a lock washer to the hardware assembly.
