Based off the Makerbot Nut & Bolt demo piece, I expanded it to fit a standard sized drink can.

Make sure to print with at least 2 shells.

To achieve this, I printed the nut, then printed the mug and paused it at about 75% to screw the nut on and resume printing.

If you want to deboss something on the underside, I recommend a depth of 1mm.
