They say good things come in small packages, but that's assuming this amazing little Team Fortress 2 sentry gun even comes in a package. It's a custom job, so it may just come bubble-wrapped!
Either way, it's the work of the supremely-talented Psychobob, a whiz with the 3D printer whose work we've featured here before.
Unlike previous pieces, this one's actually for sale (unpainted) from his store for $25. What's col is that, just like the "real" thing, his guns are upgradeable, with add-on parts available which can take the gun from level 1 all the way up to level 3.
