I don't have a 3D printer, and really, really don't care whether or not you can print a gun using one. But try to censor information about it, and I'll mirror it on my seedbox for as long as I can, just to piss you off.

You can see where this is going, and it doesn't have a happy ending.
If you do make one of these though, for the love of God embed a chunk of metal. These things wouldn't be legal without it (metal detectors).
Why you have to explain anything? As far as I know, you do not owe anybody to prove that you possess anything you have legally, if they suspect it is illegal they have to prove it.
