AA to C size Battery Adapter

This allows you to insert a AA size battery and use that battery in places that require a C size battery.  I like to keep lithium AA's in my flashlights, because the alkaline batteries freeze and leak in the winter in Ohio.  I had one flashlight that takes C cells.  I downloaded a few of the other adapter available and I didn't like how they fit.  So I designed my own.  My design uses slightly less plastic then the others and does not require any supports.
