3D printing stories

 
The holidays tend to sneak up on most of us, which is interesting given the proliferation of holiday-themed stuff that surrounds us this time of year. Nonetheless, we'd be remiss to pretend like it doesn't. It most noticeably sneaks up on our bank accounts, as we scramble to get everyone from our boss to our brother the perfect gift.

Heck, if that's not what 3D printers are for, then I've haven't the slightest idea why we've got them.
