nice tut, good way to do it, and great job of explaining it. 2 pieces of constructive criticism, however.
1. I beleive you mean inches, and not mm in the size description of the front piece. cause .3 x 2.1mm is alot smaller than the front clip
2. please, please take some clear pics. my eyes seriously hurt from trying to focus what I'm looking at. you're holding the camera too close to the body. pull the camera away from it, and then crop the edges out in MS Paint before you post the image. it really takes away from what really is a great tutorial!
