Knurled AA battery container with screw on lid.

As a Fusion 360 exercise with knurling and threads, I created a knurled AA battery container with a screw on lid. It holds 7 AA batteries.

EDIT 2016/7/10: To make it more easy to grip the lid and reach for the batteries, I modified the container in a way that the batteries stick out of the bottom part of the container. Please use the files for V3 if you want these changes.
