Camera Lens-Hood SMILE attachment - 58mm Canon T3i

I came up with this idea while printing off a lens hood for my Canon Rebel T3i.
It's a decoration that can be attached using the same ring as the hood. You can put words, or design something with bobbles to make a child laugh or pay attention as you go for that perfect shot and get them to look right at the lens.
I've included the basic ring, as well as the "SMILE" version that I made in the attached files.
NOTE: This could mess with some people who use the "Auto" features on their camera. Such as Auto Focus, Light etc. The ring rotates as you zoom and focus, so it may not always be the right way up, and might block your auto focus beam. So it's not perfect, but good for a laugh.
Fits a 58mm Canon lens.
Enjoy!
