Stanley Pint Lid

Modification to a Stanley Beer Pint 16 oz Stacker Cup Lid to narrow the opening and employ a vent hole.

The original design (credit to baddan18) works great, but I wanted a little more closure to keep my coffee warm while reducing the saw dust that could fall into it. Also, because of the narrowed opening, I put a small, but effective, vent hole on the opposite side. Nothing too fancy; just a little tweak to a good design.
