3D printing - now we can pirate everything!

So I've been getting a little excited by the whole 3D printing thing, I doubt I'm the only one. Need a cover for your phone? Copy your old one, and when it breaks, print a new one! Need some cheap promo products, want to build your own custom gaming army, run out of clothes pegs? All can easily be fixed with the magic replicator of 3D printing. We've already seen people trying to print snowboards (not great...) but as the technology improves and the materials we can use get more versatile there will be almost no limit to what we can make. Then today, I had a quick look on pirate bay (not to do anything illegal I swear) and I notice their new category. Physibles... The blueprints for 3D printable products, and it got me thinking. If I can make a copy of a clothes peg to re-produce as many as I need great, but who's copyright am I using there? And am I allowed to copy it? Surely I would still have to buy new ones instead of copying someone else's design? And then, I could upload the scanned data, and allow other people to use that data to create their own clothes pegs, virtually for free. Now I doubt we have to worry about pegs too much, but what about specific designs, products that manufacturers put hours into, only to have the first buyer upload them and boom, everyones got the latest gadget or gizmo. Sure we can't do metal (yet) but there's plenty of plastic stuff out there. The first that comes to my mind is snowboard bindings, expensive and complex bits of kit, that could effectively be reproduce for a fraction of the cost - but most importantly, with no payment to the original designers. Remember that these sorts of products are not just drawn and made, but years of development go into them, teams of designers and testers making sure they actually work, and do the best possible job. Ok, so with plastics compounds and blah blah, a copied pair won't be the same but I'm sure they'll fix that soon enough too. Models as well, Games Workshop in the UK charges a tonne for little plastic figures for its games, and now we're going to be able to make our own? Those guys are screwed! So what's going to happen if we can download our new shoes without paying for them? Seems like the winners here are going to be the people with the printers and the people making the raw material... How much is one of the those printers? Perhaps it will be a step towards a less capitalist world? If you can't charge us for things, then we can be free to work together?
