Pinhole For Canon

Hi

I'm 14 and I made this pinhole "lens" for my canon camera using 123d Design.
I've included 2 files: 1 with my name and 1 without.
I just designed this for my personal needs, so don't expect too much from it.
Please note: the one without my name doesn't have a smooth edge.
Just look at the models and you'll see!
Please read the txt file in the downloads!

Judging by the comments I can see that the hole is too big for some, though for me it worked fine.

PLEASE KEEP IN
