So, I was happily punching away, and being incredibly delicate with the parts, so I wasn't inspecting the undersides. I flipped them as a bunch, so when I was popping out the front wall, my fingers were touching yucky. Anyhow, I flipped it over and found this! Is this...normal? I mean, it looks terrible, the gap is kind of big, and I don't know if it is expected, or if there is a foolproof way to fix it. I don't think it should be like this...but what do I know!
I can't upload the picture...here is the link http://imgur.com/a/IIJ5s Thanks!
