I think you do deserve it--freedom is preserved by thousands of tiny acts every day.
I'm quite aware of the 3-D printer craze and was keenly following it (Fab-at-home, reprap, MakerBot). I've got notebooks full of improvements and experiments. It looks like great fun, I just haven't gotten to building yet.

This sort of stuff is sooo much more fun and productive than fighting the president over nonsense--that's part of my frustration politically. I wish they'd just finally let us alone so we could do cool stuff, not constantly distracted and worrying about their schemes.
