And here's a blog post I wrote about why I think it didn't work: http://www.pigsdontfly.com/2013/05/7-things-i-learned-from-u...
If you switched to 3D Printed materials, I think the costs would be much less and you could have funded it with the amount of money you already collected.
Couple of suggestions though: Shipping: if you can analyse where backers are coming from, why not try to cut a deal with stores or brew shops/brew pubs which you could strategically locate where your biggest clusters of customers are. That way you could ship in bulk to single locations, and mail out certificates for backers to go and pick up their beerend. Explain why you're doing this to the backers, and for the stores, send extra they can sell, but they have to hold the reserve amount for backers. Plus you would be sending people to their stores that take their beer storage seriously, so they may turn out to be good customers.
Marketing: Bottle end: maybe change the marketing focus of the product, as you said it can be used for wine bottles, cans whatever. Go all out, dev the 2.0 for glass shelves versions, patent it and sell it to fridge makers
Good luck!
Did you think of partnering with quirky?
P.s. I would love to try printing this on my replicator2
