I'm not a modeler by many means, and getting this right wasn't as easy as just creating a hexagon. I had to change the top and bottom of the hexagon from an ngons to triangular faces. However, once I got that squared away, it worked! It's nothing impressive by any means, but it's a very simple shape that was missing that I wanted and figured if I wanted it, someone else would and I'd share it. =)
This is what 7 look like alongside a default square. You can download it on GitHub. Hopefully this helps someone else out.
